[Docket No. 03-16476; Notice 2]
RIN No. 2127-AJ30
Federal Motor Vehicle Safety Standards; Occupant Crash Protection
AGENCY: National Highway Traffic Safety Administration (NHTSA),
Department of Transportation (DOT).
ACTION: Final rule, partial response to petitions for reconsideration.
-----------------------------------------------------------------------
SUMMARY: This final rule temporarily permits compliance with Federal
Motor Vehicle Safety Standard (FMVSS) No. 208, Occupant crash
protection, according to the test procedures of that standard prior to
the amendments made by the November 19, 2003, final rule.\1\ This
document amends FMVSS No. 208 through the adoption of FMVSS 208a, which
contains these ``old'' test procedures. This final rule permits the
certification of motor vehicles under the ``old'' test procedures until
August 31, 2004.
---------------------------------------------------------------------------
\1\ See, 68 Federal Register 65179.
---------------------------------------------------------------------------
The agency received seven petitions for reconsideration of the
November 2003 final rule, requesting that NHTSA consider modifying
certain requirements of the amended FMVSS No. 208. Specifically,
petitioners asked that the agency reconsider: The seat positioning
procedures for the barrier tests, low risk deployment tests, and other
test procedures; the test procedure for positioning the left foot of
the 5th percentile adult female test dummy (barrier test); the ``chin
on rim'' low risk deployment test procedure; the dummy positioning
procedure for the head-on-instrument panel low risk deployment test
with the 6-year-old test dummy; the definition of Plane C and D in the
dummy positioning procedure for low risk deployment; and the effective
date and content of Appendix A.
Petitioners have indicated that compliance with the amended
requirements of FMVSS No. 208, prior to resolution of petitions for
reconsideration, would cause substantial economic hardship because
certification testing for the model year 2004 fleet has completed. This
rulemaking partially responds to the petitions for reconsideration by
permitting manufacturers to temporarily certify vehicles according to
the test procedures required prior to the effective date of the
November 2003 final rule.
DATES: This final rule becomes effective on January 27, 2004.

IV. Regulatory Analyses and Notices
I. Background
FMVSS No. 208 specifies the performance requirements for the
protection of vehicle occupants in crashes. On November 19, 2003, the
agency published a final rule that responded, in part, to petitions for
reconsideration of the amendments to detailed seat and dummy
positioning procedures we made in December 2001 to our May 2000
Advanced Air Bag Rule. In particular, we amended portions of FMVSS No.
208 regarding seat positioning procedures when using the 5th percentile
adult female test dummy in the barrier test and the low risk deployment
test; when using the 3-year-old and 6-year-old test dummies in the low
risk deployment test; the fore and aft seat location for rear facing
child restraint systems (RFCRSs); and the seat track position for the
low risk deployment test. We also responded to petitions for
reconsideration regarding test dummy positioning procedure issues,
specifically those addressing foot positioning of the 5th percentile
adult female test dummy; positioning out-of-position test dummies; and
positioning of test dummy hands. The November 2003 final rule amended
the definitions of ``Plane C'' and ``Plane D'' as they relate to test
dummy positioning, Point 1 under the low risk deployment tests, and
addressed other reference points and definitions. The November 2003
final rule also amended the list of child
[[Page 3838]]
restraint systems required for certain compliance testing.
II. Petitions for Reconsideration
In response to the November 2003 final rule, the agency received
seven petitions for reconsideration. Petitions were submitted by
Evenflo Company, Inc. (Evenflo), Maserati S.p.A. (Maserati), Alliance
for Automobile Manufacturers (Alliance), TRW Automotive (TRW),
Automotive Occupant Restraint Council (AORC), American Honda Motor Co.,
Inc. (Honda), and Ferrari S.p.A. (Ferrari). Petitioners have asked the
agency to reconsider the following issues.
A. Seat Positioning Procedures
The Alliance has requested that the agency specify a vertical seat
position when determining the seat cushion reference angle.
Specifically, the Alliance requested that the seat be positioned in the
full rear and full down position when determining the seat cushion
reference angle. The Alliance also requested that S16.2.10.3.2 and
S16.2.10.3.3 of FMVSS No. 208 be amended to specify that the reference
point used in these sections is the seat cushion reference point.
B. Left foot--5th percentile adult female test dummy (Barrier test)
The Alliance, Honda, and Ferrari petitioned to permit positioning
of the left foot of the 5th percentile adult female test dummy in a
manner more representative of a ``real world'' configuration. Ferrari
and Honda requested that the left foot be permitted to rest on the foot
rest. The Alliance requested that if spacer blocks are to be required,
then the agency should specify the material properties of the spacer
blocks for consistency in testing. Honda requested that the amendments
for positioning the left foot of the 5th percentile adult female test
dummy adopted in the November 2003 final rule be postponed until
September 1, 2004. The Alliance requested that the amendments for
positioning the left foot of the 5th percentile adult female test
dummy, along with the rest of the November 2003 final rule, be
postponed until September 1, 2005.
C. ``Chin on Rim'' Test Procedure
The Alliance and Honda requested that the agency amend the chin on
rim test procedure to provide for consistency and repeatability in
testing out-of-position drivers. The Alliance requested that for
vehicle models with adjustable and non-adjustable steering wheels, the
adjustable steering wheel should be positioned as close as possible to
the position of the non-adjustable steering wheel. When spacer blocks
are required to position the dummy's chin on the steering wheel, Honda
requested that the agency specify the shape of the blocks. Honda stated
that the pre-test load applied to the neck can vary with the shape of
the spacer blocks. Honda also requested that the amendments for the
``chin on rim'' test procedure adopted in the November 2003 final rule
be postponed until September 1, 2004.
D. Head-on-Instrument Panel Test Procedure
Honda petitioned the agency to permit rotation of the lower legs
when positioning the head of the six-year-old dummy on the instrument
panel, in order to prevent bracing by the feet on the vehicle floor.
Honda stated that this bracing prevents the torso from being rotated
into position.
Honda also requested that spacer blocks be permitted when space is
present between the six-year-old dummy's feet and the vehicle floor.
Honda stated that variation of the feet due to lack of contact with the
floor results in variation in the force required to maintain the thigh
angle. Again with regards to the six-year-old dummy, Honda requested
that the head-on-instrument panel test procedure specify the point and
direction for applying the 222 N force to prevent differences in dummy
position.
Honda further requested that the amendments for the head-on-
instrument-panel test procedure adopted in the November 2003 rule be
postponed until September 1, 2004.
E. Definition of Planes C and D
The Alliance, Maserati, and Ferrari requested clarification of the
procedure for determining the volumetric centers of an uninflated and
statically inflated air bag, which are used to define Planes C and D.
Maserati stated that the new definition of Plane C may alter the
positioning of the dummy in low risk deployment testing by 50 mm and
that the effect of this altered position on compliance is unknown at
this time. The Alliance stated that one of its members has reported
that the redefined Plane C may alter the positioning of the dummy by 30
mm.
The Alliance requested that the effective date for the amended
definitions of Planes C and D be postponed to September 1, 2005.
Ferrari requested a two year lead time and Maserati requested a three
year lead time. AORC has requested that the agency revert to the
previous method for defining Planes C and D.
F. Appendix A
Evenflo and TRW have requested that Appendix A be amended to
reflect child restraint systems (CRSs) currently manufactured and
available for retail purchase. Evenflo stated that several of the
discontinued CRS models in Appendix A are no longer available. TRW
petitioned the agency to create a separate Appendix to indicate which
CRSs will be used in testing through at least 2006. To facilitate the
use of automatic suppression systems based on weight detection, Honda
petitioned the agency to limit the weight of CRSs. Honda also
petitioned the agency to permit 18 months of lead time for the amended
Appendix A.
The Alliance requested that the agency develop a procedure for
installing CRSs equipped with lower anchorages and tether attachments.
The Alliance stated that artificially tight installations can cause
some occupant classification systems to misclassify the occupant. The
Alliance also requested the effective date for the revised Appendix A
be postponed until September 1, 2005.
III. Final Rule
The agency set a January 20, 2004 effective date for the amendments
to the FMVSS No. 208 seat and dummy positioning procedures in the
November 2003 final rule. The petitions filed by Evenflo, Maserati, the
Alliance, TRW, AORC, Honda, and Ferrari have asked the agency to
reconsider several aspects of that rulemaking. NHTSA is currently
considering all seven petitions.
Given that the January 20, 2004 effective date occurred mid-model
year, the agency has determined that it is appropriate to first
partially respond to petitions concerning the effective date of the
November 2003 final rule. Manufacturers are currently required to
certify at least 20 percent of all vehicles manufactured between
September 1, 2003 and August 31, 2004 as fully complying with the
advanced air bag requirements, unless advanced credits are utilized.
These production dates roughly correspond with the model year 2004
fleet. Much of the testing that manufacturers conduct to certify
compliance of the 2004 model year fleet has already been done. Although
we believe the new positioning procedures result in more accurate and
repeatable dummy placement, the new procedures could result in a test
dummy being placed differently relative to the air bag than it was
during vehicle certification. As a result, it is possible that injury
criteria could be exceeded under the new procedures, even though they
were
[[Page 3839]]
not exceeded in certification testing. If so, manufacturers may need to
make minor modifications to their designs to assure compliance with the
new requirement. However, we note that no petitioner provided
comparative test data between old and new dummy positions. Nor did any
manufacturer state that they could not comply with the test
requirements using the new dummy positions. Nonetheless, the agency is
permitting compliance according to the testing procedures required by
FMVSS No. 208 immediately prior to the November 2003 amendments.
This document adopts FMVSS No. 208a, which contains the pre-
November 2003 final rule test procedures. Manufacturers may rely on the
test procedures in FMVSS No. 208a until August 31, 2004, after which,
the manufacturers will be required to meet the new requirements of
FMVSS No. 208. (The November 2003 amendments to Appendix A already have
an effective date of September 1, 2004.) If a manufacturer opts to
certify a vehicle according to the procedures in FMVSS No. 208a, it
must certify using all of the relevant seat and dummy positioning
procedures in FMVSS No. 208a in place of the corresponding test
procedures in FMVSS. No. 208. We have decided against any further
extension of the old procedures because we believe the new positioning
procedures should not require any more than minor modifications by
affected manufacturers. Other issues raised in the petitions for
reconsideration will be addressed by the agency in a separate document.
The agency believes that a partial response to the petitions for
reconsideration is necessary so motor vehicle manufacturers do not face
substantial economic hardship associated with certain new requirements
of the amended FMVSS No. 208. As discussed in the petitions, the
updated requirements of FMVSS No. 208 may necessitate retesting and
recertification of occupant protection systems. By permitting
compliance according to the old test procedures until August 31, 2004,
vehicle manufacturers may avoid mid-model year product changes that
would otherwise result from the November 2003 final rule, which went
into effect on January 20, 2004.
NHTSA expects that all other issues raised in the petitions will be
fully addressed prior to the new, September 1, 2004 effective date. In
the event, however, that these issues have not been resolved, all
affected manufacturers will be required to meet the new requirements.
Effective dates of agency final rules are not stayed due to outstanding
petitions for reconsideration of those rules.
IV. Regulatory Analyses and Notices
A. Economic Impacts
Executive Order 12866, ``Regulatory Planning and Review'' (58 FR
51735, October 4, 1993), provides for making determinations whether a
regulatory action is ``significant'' and therefore subject to Office of
Management and Budget (OMB) review and to the requirements of the
Executive Order. The Order defines a ``significant regulatory action''
as one that is likely to result in a rule that may:
(1) Have an annual effect on the economy of $100 million or more or
adversely affect in a material way the economy, a sector of the
economy, productivity, competition, jobs, the environment, public
health or safety, or State, local, or Tribal governments or
communities;
(2) Create a serious inconsistency or otherwise interfere with an
action taken or planned by another agency;
(3) Materially alter the budgetary impact of entitlements, grants,
user fees, or loan programs or the rights and obligations of recipients
thereof; or
(4) Raise novel legal or policy issues arising out of legal
mandates, the President's priorities, or the principles set forth in
the Executive Order.
This rulemaking document was not reviewed under Executive Order
12866. It is not significant within the meaning of the DOT Regulatory
Policies and Procedures. It does not impose any burden on manufacturers
and effectively extends the compliance date for existing regulatory
requirements for an additional seven months. The agency believes that
this impact is so minimal as to not warrant the preparation of a full
regulatory evaluation.
B. Regulatory Flexibility Act
Pursuant to the Regulatory Flexibility Act, we have considered the
impacts of this rulemaking action will have on small entities (5 U.S.C.
601 et seq.). I certify that this rulemaking action will not have a
significant economic impact upon a substantial number of small entities
within the context of the Regulatory Flexibility Act. The following is
our statement providing the factual basis for the certification (5
U.S.C. 605(b)). This action will not have a significant economic impact
on a substantial number of small businesses because it does not
significantly change the requirements of the November 2003 final rule.
Small organizations and small governmental units will not be
significantly effected since the potential cost impacts associated with
this rule remain unchanged from the November 2003 final rule.
C. Environmental Impacts
We have not conducted an evaluation of the impacts of this final
rule under the National Environmental Policy Act. This rulemaking
action effectively extends the date by which the manufacturers must
comply with the newly upgraded requirements of FMVSS No. 208. This
rulemaking does not impose any change that would have any environmental
impacts. Accordingly, no environmental assessment is required.
D. Executive Order 13132 (Federalism)
E.O. 13132 requires NHTSA to develop an accountable process to
ensure ``meaningful and timely input by State and local officials in
the development of regulatory policies that have federalism
implications.'' E.O. 13132 defines the term ``Policies that have
federalism implications'' to include regulations that have
``substantial direct effects on the States, on the relationship between
the national government and the States, or on the distribution of power
and responsibilities among the various levels of government.'' Under
E.O. 13132, NHTSA may not issue a regulation that has federalism
implication, that imposes substantial direct compliance costs, and that
is not required by statute, unless the Federal government provides the
funds necessary to pay the direct compliance costs incurred by State
and local governments, or NHTSA consults with State and local officials
early in the process of developing the proposed regulation.
This final rule will not have substantial direct effects on the
States, on the relationship between the national government and the
States, or on the distribution of power and responsibilities among the
various levels of government as specified in E.O. 13132. Thus, the
requirements of section 6 of the Executive Order do not apply to this
rule.
E. The Unfunded Mandates Reform Act
The Unfunded Mandates Reform Act of 1995 (Pub. L. 104-4) requires
agencies to prepare a written assessment of the costs, benefits and
other effects of proposed or final rules that include a Federal mandate
likely to result in the expenditure by State, local or tribal
governments, in the aggregate, or by the private sector, of more than
$100
[[Page 3840]]
million annually. This action, which permits manufacturers to rely on
test procedures required prior to the November 2003 upgrade for an
additional seven months, will not result in additional expenditures by
state, local or tribal governments or by any members of the private
sector. Therefore, the agency has not prepared an economic assessment
pursuant to the Unfunded Mandates Reform Act.
F. Paperwork Reduction Act
There are no information collection requirements in this rule.
G. Regulation Identifier Number (RIN)
The Department of Transportation assigns a regulation identifier
number (RIN) to each regulatory action listed in the Unified Agenda of
Federal Regulations. The Regulatory Information Service Center
publishes the Unified Agenda in April and October of each year. You may
use the RIN contained in the heading at the beginning of this document
to find this action in the Unified Agenda.
H. Plain Language
Executive Order 12866 requires each agency to write all rules in
plain language. Application of the principles of plain language
includes consideration of the following questions:
--Have we organized the material to suit the public's needs?
--Are the requirements in the rule clearly stated?
--Does the rule contain technical language or jargon that is not clear?
--Would a different format (grouping and order of sections, use of
headings, paragraphing) make the rule easier to understand?
--Would more (but shorter) sections be better?
--Could we improve clarity by adding tables, lists, or diagrams?
--What else could we do to make the rule easier to understand?
If you have any responses to these questions, please forward them
to Chris Calamita, Office of Chief Counsel, National Highway Traffic
Safety Administration, 400 Seventh Street, SW., Washington, DC 20590.
I. National Technology Transfer and Advancement Act
Under the National Technology and Transfer and Advancement Act of
1995 (NTTAA) (Pub. L. 104-113), ``all Federal agencies and departments
shall use technical standards that are developed or adopted by
voluntary consensus standards bodies, using such technical standards as
a means to carry out policy objectives or activities determined by the
agencies and departments.'' This document permits temporary compliance
with FMVSS No. 208 according to test procedures prior to amendments
made in the November 2003 final rule. No new standards or procedures
are adopted by this document.
J. Privacy Act
Anyone is able to search the electronic form of all comments
received into any of our dockets by the name of the individual
submitting the comment (or signing the comment, if submitted on behalf
of an association, business, labor union, etc.). You may review DOT's
complete Privacy Act Statement in the Federal Register published on
April 11, 2000 (Volume 65, Number 70; Pages 19477-78), or you may visit

571.208a Optional test procedures for vehicles manufactured between
January 27, 2004 and August 31, 2004.
For vehicles manufactured between January 27, 2004 and August 31,
2004, a manufacturer may, at its option, comply with certain
requirements of Standard No. 208 in accordance with the test procedures
set forth in this Sec. 571.208a instead of the corresponding test
procedures in Sec. 571.208.
S1 through S15 [Reserved] See Sec. 571.208, S1 through S15.
S16. Test procedures for rigid barrier test requirements using 5th
percentile adult female dummies.
S16.1 General provisions. Crash testing to determine compliance
with the requirements of S15 of this standard is conducted as specified
in the following paragraphs (a) and (b).
(a) Belted test. Place a 49 CFR part 572 subpart O 5th percentile
adult female test dummy at each front outboard seating position of a
vehicle, in accordance with the procedures specified in S16.3 of this
standard. Impact the vehicle traveling longitudinally forward at any
speed, up to and including 48 km/h (30 mph), into a fixed rigid barrier
that is perpendicular within a tolerance of 5
degrees to the line of travel of the vehicle under the applicable
conditions of S16.2 of this standard.
(b) Unbelted test. Place a 49 CFR part 572 subpart O 5th percentile
adult female test dummy at each front outboard seating position of a
vehicle, in accordance with the procedures specified in S16.3 of this
standard, except S16.3.5. Impact the vehicle traveling longitudinally
forward at any speed, from 32 km/h (20 mph) to 40 km/h (25 mph),
inclusive, into a fixed rigid barrier that is perpendicular within a
tolerance of 5 degrees to the line of travel of
the vehicle under the applicable conditions of S16.2 of this standard.
S16.2 Test conditions.
S16.2.1 The vehicle, including test devices and instrumentation, is
loaded as in S8.1.1 of FMVSS No. 208.
S16.2.2 Movable vehicle windows and vents are placed in the fully
closed position, unless the vehicle manufacturer chooses to specify a
different adjustment position prior to the time the vehicle is
certified.
S16.2.3 Convertibles and open-body type vehicles have the top, if
any, in place in the closed passenger compartment configuration.
S16.2.4 Doors are fully closed and latched but not locked.
S16.2.5 The dummy is clothed in form fitting cotton stretch
garments with short sleeves and above the knee length pants. A size
7\1/2\W shoe which meets the configuration and size specifications of
MIL-S-21711E (see S4.7) or its equivalent is placed on each foot of the
test dummy.
S16.2.6 Limb joints are set at one g, barely restraining the weight
of the limb when extended horizontally. Leg joints are adjusted with
the torso in the supine position.
S16.2.7 Instrumentation shall not affect the motion of dummies
during impact.
S16.2.8 The stabilized temperature of the dummy is at any level
between 20.6 C and 22.2 C (69
F to 72 F).
S16.2.9 Steering wheel adjustment.
S16.2.9.1 Adjust a tiltable steering wheel, if possible, so that
the steering wheel hub is at the geometric center of its full range of
driving positions.
S16.2.9.2 If there is no setting detent at the mid-position, lower
the steering wheel to the detent just below the mid-position.
S16.2.9.3 If the steering column is telescoping, place the steering
column
[[Page 3841]]
in the mid-position. If there is no mid-position, move the steering
wheel rearward one position from the mid-position.
S16.2.10 Driver and passenger seat set-up.
S16.2.10.1 Lumbar support adjustment. Position adjustable lumbar
supports so that the lumbar support is in its lowest, retracted or
deflated adjustment position.
S16.2.10.2 Other seat adjustments. Position any adjustable parts of
the seat that provide additional support so that they are in the lowest
or most open adjustment position.
S16.2.10.3 Seat position adjustment. If the passenger seat does not
adjust independently of the driver seat, the driver seat shall control
the final position of the passenger seat.
S16.2.10.3.1 If the seat is adjustable in the fore and aft and/or
vertical directions, move the seat to the rearmost position at the full
down height adjustment. If the seat cushion adjusts fore and aft,
independent of the seat back, set this adjustment to the full rearward
position. If the seat cushion contains a height adjustment, independent
of the seat back, set this adjustment to the full down position. Record
a seat cushion reference angle.
S16.2.10.3.2 Using only controls which move the seat fore and aft,
move the seat to the full forward position. If seat adjustments other
than fore-aft are present and the seat cushion reference angle changes
from that measured in S16.2.10.3.1, use those adjustments to maintain
as closely as possible the angle recorded in S16.2.10.3.1.
S16.2.10.3.3 If the seat height is adjustable, determine the
maximum and minimum heights at this position, while maintaining, as
closely as possible, the angle recorded in S16.2.10.3.1. Set the seat
at the midpoint height with the seat cushion reference angle set as
closely as possible to the angle recorded in S16.2.10.3.1. Mark
location of the seat for future reference.
S16.3 Dummy seating positioning procedures. The 49 CFR part 572
subpart O 5th percentile adult female test dummy is positioned as
follows:
S16.3.1 General provisions and definitions.
S16.3.1.1 All angles are measured with respect to the horizontal
plane unless otherwise stated.
S16.3.1.2 The dummy's neck bracket is adjusted to align the zero
degree index marks.
S16.3.1.3 The term ``midsagittal plane'' refers to the vertical
plane that separates the dummy into equal left and right halves.
S16.3.1.4 The term ``vertical longitudinal plane'' refers to a
vertical plane parallel to the vehicle's longitudinal centerline.
S16.3.1.5 The term ``vertical plane'' refers to a vertical plane,
not necessarily parallel to the vehicle's longitudinal centerline.
S16.3.1.6 The term ``transverse instrumentation platform'' refers
to the transverse instrumentation surface inside the dummy's skull
casting to which the neck load cell mounts. This surface is
perpendicular to the skull cap's machined inferior-superior mounting
surface.
S16.3.1.7 The term ``thigh'' refers to the femur between, but not
including, the knee and the pelvis.
S16.3.1.8 The term ``leg'' refers to the lower part of the entire
leg including the knee.
S16.3.1.9 The term ``foot'' refers to the foot including the ankle.
S16.3.1.10 The longitudinal centerline of a bucket seat cushion is
determined at the widest part of the seat cushion. Measure
perpendicular to the longitudinal centerline of the vehicle.
S16.3.1.11 For leg and thigh angles use the following references:
S16.3.1.11.1 Thigh--a straight line on the thigh skin between the
center of the \1/2\-13 UNC-2B tapped hole in the upper leg femur clamp
(see drawings 880105-504 (left thigh) and 880105-505 (right thigh),
upper leg femur clamp) and the knee pivot shoulder bolt (part 880105-
527 in drawing 880105-528R & 528L, sliding knee assy. w/o pot).
S16.3.1.11.2 Leg--a straight line on the leg skin between the
center of the ankle shell (parts 880105-609 & 633 in drawing 880105-
660, ankle assembly) and the knee pivot shoulder bolt (part 880105-527
in drawing 880105-528R & 528L, sliding knee assy. w/o pot).
S16.3.2 Driver dummy positioning.
S16.3.2.1 Driver torso/head/seat back angle positioning.
S16.3.2.1.1 With the seat in the position determined in S16.2.10,
use only the controls which move the seat fore and aft to place the
seat in the rearmost position, without adjusting independent height
controls. If the seat cushion reference angle automatically changes as
the seat is moved from the full forward position, maintain, as closely
as possible, the seat cushion reference angle in S16.2.10.3.1, for the
final forward position when measuring the pelvic angle as specified in
S16.3.2.1.11.
S16.3.2.1.2 Fully recline the seat back, if adjustable. Install the
dummy into the driver's seat, such that when the legs are positioned
120 degrees to the thighs, the calves of the legs are not touching the
seat cushion.
S16.3.2.1.3 Bucket seats. Center the dummy on the seat cushion so
that its midsagittal plane is vertical and coincides with the vertical
longitudinal plane through the center of the seat cushion.
S16.3.2.1.4 Bench seats. Position the midsagittal plane of the
dummy vertical and parallel to the vehicle's longitudinal centerline
and aligned with the center of the steering wheel rim.
S16.3.2.1.5 Hold the dummy's thighs down and push rearward on the
upper torso to maximize the dummy's pelvic angle.
S16.3.2.1.6 Place the legs at 120 degrees to the thighs. Set the
initial transverse distance between the longitudinal centerlines at the
front of the dummy's knees at 160 to 170 mm (6.3 to 6.7 in), with the
thighs and legs of the dummy in vertical planes. Push rearward on the
dummy's knees to force the pelvis into the seat so there is no gap
between the pelvis and the seat back or until contact occurs between
the back of the dummy's calves and the front of the seat cushion.
S16.3.2.1.7 Gently rock the upper torso relative to the lower torso
laterally in a side to side motion three times through a 5 degree arc (approximately 51 mm (2 in) side to side)
to reduce friction between the dummy and the seat.
S16.3.2.1.8 If needed, extend the legs slightly so that the feet
are not in contact with the floor pan. Let the thighs rest on the seat
cushion to the extent permitted by the foot movement. Keeping the leg
and the thigh in a vertical plane, place the foot in the vertical
longitudinal plane that passes through the centerline of the
accelerator pedal. Rotate the left thigh outboard about the hip until
the center of the knee is the same distance from the midsagittal plane
of the dummy as the right knee 5 mm ( 0.2 in). Using only controls which move the seat fore
and aft, attempt to return the seat to the full forward position. If
either of the dummy's legs first contacts the steering wheel, then
adjust the steering wheel, if adjustable, upward until contact with the
steering wheel is avoided. If the steering wheel is not adjustable,
separate the knees enough to avoid steering wheel contact. Proceed with
moving the seat forward until either the leg contacts the vehicle
interior or the seat reaches the full forward position. (The right foot
may contact and depress the accelerator and/or change the angle of the
foot with respect to the leg during seat movement.) If necessary to
avoid contact with the vehicles brake or clutch
[[Page 3842]]
pedal, rotate the test dummy's left foot about the leg. If there is
still interference, rotate the left thigh outboard about the hip the
minimum distance necessary to avoid pedal interference. If a dummy leg
contacts the vehicle interior before the full forward position is
attained, position the seat at the next detent where there is no
contact. If the seat is a power seat, move the seat fore and aft to
avoid contact while assuring that there is a maximum of 5 mm (0.2 in)
distance between the vehicle interior and the point on the dummy that
would first contact the vehicle interior. If the steering wheel was
moved, return it to the position described in S16.2.9. If the steering
wheel contacts the dummy's leg(s) prior to attaining this position,
adjust it to the next higher detent, or if infinitely adjustable, until
there is 5 mm (0.2 in) clearance between the wheel and the dummy's
leg(s).
S16.3.2.1.9 For vehicles without adjustable seat backs, adjust the
lower neck bracket to level the head as much as possible. For vehicles
with adjustable seat backs, while holding the thighs in place, rotate
the seat back forward until the transverse instrumentation platform of
the head is level to within 0.5 degree, making
sure that the pelvis does not interfere with the seat bight. Inspect
the abdomen to ensure that it is properly installed. If the torso
contacts the steering wheel, adjust the steering wheel in the following
order until there is no contact: Telescoping adjustment, lowering
adjustment, raising adjustment. If the vehicle has no adjustments or
contact with the steering wheel cannot be eliminated by adjustment,
position the seat at the next detent where there is no contact with the
steering wheel as adjusted in S16.2.9. If the seat is a power seat,
position the seat to avoid contact while assuring that there is a
maximum of 5 mm (0.2 in) distance between the steering wheel as
adjusted in S16.2.9 and the point of contact on the dummy.
S16.3.2.1.10 If it is not possible to achieve the head level within
0.5 degrees, minimize the angle.
S16.3.2.1.11 Measure and set the dummy's pelvic angle using the
pelvic angle gage (drawing TE-2504, incorporated by reference in 49 CFR
part 572, subpart O, of this chapter). The angle shall be set to 20.0
degrees 2.5 degrees. If this is not possible,
adjust the pelvic angle as close to 20.0 degrees as possible while
keeping the transverse instrumentation platform of the head as level as
possible by adjustments specified in S16.3.2.1.9 and S16.3.2.1.10.
S16.3.2.1.12 If the dummy is contacting the vehicle interior after
these adjustments, move the seat rearward until there is a maximum of 5
mm (0.2 in) between the contact point of the dummy and the interior of
the vehicle or if it has a manual seat adjustment, to the next rearward
detent position. If after these adjustments, the dummy contact point is
more than 5 mm (0.2 in) from the vehicle interior and the seat is still
not in its forwardmost position, move the seat forward until the
contact point is 5 mm (0.2 in) or less from the vehicle interior, or if
it has a manual seat adjustment, move the seat to the closest detent
position without making contact, or until the seat reaches its
forwardmost position, whichever occurs first.
S16.3.2.2 Driver foot positioning.
S16.3.2.2.1 If the vehicle has an adjustable accelerator pedal,
adjust it to the full forward position. Rest the right foot of the test
dummy on the undepressed accelerator pedal with the rearmost point of
the heel on the floor pan in the plane of the pedal. If the foot cannot
be placed on the accelerator pedal, set it initially perpendicular to
the leg and then place it as far forward as possible in the direction
of the pedal centerline with the rearmost point of the heel resting on
the floor pan. If the vehicle has an adjustable accelerator pedal and
the right foot is not touching the accelerator pedal when positioned as
above, move the pedal rearward until it touches the right foot. If the
accelerator pedal in the full rearward position still does not touch
the foot, leave the pedal in that position.
S16.3.2.2.2 If the ball of the foot does not contact the pedal,
change the angle of the foot relative to the leg such that the toe of
the foot contacts the undepressed accelerator pedal.
S16.3.2.2.3 Place the left foot on the toe-board with the rearmost
point of the heel resting on the floor pan as close as possible to the
point of intersection of the planes described by the toe-board and
floor pan, and not on the wheel-well projection or foot rest.
S16.3.2.2.4 If the left foot cannot be positioned on the toe board,
place the foot perpendicular to the lower leg centerline as far forward
as possible with the heel resting on the floor pan.
S16.3.2.2.5 If necessary to avoid contact with the vehicle's brake
or clutch pedal, rotate the test dummy's left foot about the lower leg.
If there is still pedal interference, rotate the left leg outboard
about the hip the minimum distance necessary to avoid the pedal
interference. If the left foot does not contact the floor pan, place
the foot parallel to the floor and place the leg as perpendicular to
the thigh as possible.
S16.3.2.3 Driver arm/hand positioning.
S16.3.2.3.1 Place the dummy's upper arms adjacent to the torso with
the arm centerlines as close to a vertical longitudinal plane as
possible.
S16.3.2.3.2 Place the palms of the dummy in contact with the outer
part of the steering wheel rim at its horizontal centerline with the
thumbs over the steering wheel rim.
S16.3.2.3.3 If it is not possible to position the thumbs inside the
steering wheel rim at its horizontal centerline, then position them
above and as close to the horizontal centerline of the steering wheel
rim as possible.
S16.3.2.3.4 Lightly tape the hands to the steering wheel rim so
that if the hand of the test dummy is pushed upward by a force of not
less than 9 N (2 lb) and not more than 22 N (5 lb), the tape releases
the hand from the steering wheel rim.
S16.3.3 Passenger dummy positioning.
S16.3.3.1 Passenger torso/head/seat back angle positioning.
S16.3.3.1.1 With the seat in the position determined in S16.2.10,
use only the controls which move the seat fore and aft to place the
seat in the rearmost position, without adjusting independent height
controls. If the seat cushion reference angle automatically changes as
the seat is moved from the full forward position, maintain as closely
as possible the seat cushion reference angle in S16.2.10.3.1, for the
final forward position when measuring the pelvic angle as specified in
S16.3.3.1.11.
S16.3.3.1.2 Fully recline the seat back, if adjustable. Install the
dummy into the passenger's seat, such that when the legs are 120
degrees to the thighs, the calves of the legs are not touching the seat
cushion.
S16.3.3.1.3 Bucket seats. Center the dummy on the seat cushion so
that its midsagittal plane is vertical and coincides with the vertical
longitudinal plane through the center of the seat cushion.
S16.3.3.1.4 Bench seats. Position the midsagittal plane of the
dummy vertical and parallel to the vehicle's longitudinal centerline
and the same distance from the vehicle's longitudinal centerline as the
midsagittal plane of the driver dummy.
S16.3.3.1.5 Hold the dummy's thighs down and push rearward on the
upper torso to maximize the dummy's pelvic angle.
S16.3.3.1.6 Place the legs at 120 degrees to the thighs. Set the
initial
[[Page 3843]]
transverse distance between the longitudinal centerlines at the front
of the dummy's knees at 160 to 170 mm (6.3 to 6.7 in), with the thighs
and legs of the dummy in vertical planes. Push rearward on the dummy's
knees to force the pelvis into the seat so there is no gap between the
pelvis and the seat back or until contact occurs between the back of
the dummy's calves and the front of the seat cushion.
S16.3.3.1.7 Gently rock the upper torso relative to the lower torso
laterally side to side three times through a 5
degree arc (approximately 51 mm (2 in) side to side).
S16.3.3.1.8 If needed, extend the legs slightly so that the feet
are not in contact with the floor pan. Let the thighs rest on the seat
cushion to the extent permitted by the foot movement. With the feet
perpendicular to the legs, place the heels on the floor pan. If a heel
will not contact the floor pan, place it as close to the floor pan as
possible. Using only controls which move the seat fore and aft, attempt
to return the seat to the full forward position. If a dummy leg
contacts the vehicle interior before the full forward position is
attained, position the seat at the next detent where there is no
contact. If the seats are power seats, position the seat to avoid
contact while assuring that there is a maximum of 5 mm (0.2 in)
distance between the vehicle interior and the point on the dummy that
would first contact the vehicle interior.
S16.3.3.1.9 For vehicles without adjustable seat backs, adjust the
lower neck bracket to level the head as much as possible. For vehicles
with adjustable seat backs, while holding the thighs in place, rotate
the seat back forward until the transverse instrumentation platform of
the head is level to within 0.5 degrees, making
sure that the pelvis does not interfere with the seat bight. Inspect
the abdomen to insure that it is properly installed.
S16.3.3.1.10 If it is not possible to orient the head level within
0.5 degrees, minimize the angle.
S16.3.3.1.11 Measure and set the dummy's pelvic angle using the
pelvic angle gage (drawing TE-2504, incorporated by reference in 49 CFR
part 572, subpart O, of this chapter). The angle shall be set to 20.0
degrees 2.5 degrees. If this is not possible,
adjust the pelvic angle as close to 20.0 degrees as possible while
keeping the transverse instrumentation platform of the head as level as
possible as specified in S16.3.3.1.9 and S16.3.3.1.10.
S16.3.3.1.12 If the dummy is contacting the vehicle interior after
these adjustments, move the seat rearward until there is a maximum of 5
mm (0.2 in) between the contact point of the dummy and the interior of
the vehicle or if it has a manual seat adjustment, to the next rearward
detent position. If after these adjustments the dummy contact point is
more than 5 mm (0.2 in) from the vehicle interior and the seat is still
not in its forward most position, move the seat forward until the
contact point is 5 mm (0.2 in) or less from the vehicle interior, or if
it has a manual seat adjustment, move the seat to the closest detent
position without making contact, or until the seat reaches its forward
most position, whichever occurs first.
S16.3.3.2 Passenger foot positioning.
S16.3.3.2.1 Place the passenger's feet flat on the toe board.
S16.3.3.2.2 If the feet cannot be placed flat on the toe board, set
them perpendicular to the leg center lines and place them as far
forward as possible with the heels resting on the floor pan.
S16.3.3.3 Passenger arm/hand positioning.
S16.3.3.3.1 Place the dummy's upper arms in contact with the seat
back and the torso.
S16.3.3.3.2 Place the palms of the dummy in contact with the
outside of the thighs.
S16.3.3.3.3 Place the little fingers in contact with the seat
cushion.
S16.3.4 Driver and passenger adjustable head restraints.
S16.3.4.1 If the head restraint has an automatic adjustment, leave
it where the system positions the restraint after the dummy is placed
in the seat.
S16.3.4.2 Adjust each head restraint to its lowest position.
S16.3.4.3 Measure the vertical distance from the top most point of
the head restraint to the bottom most point. Locate a horizontal plane
through the midpoint of this distance. Adjust each head restraint
vertically so that this horizontal plane is aligned with the center of
gravity (CG) of the dummy head.
S16.3.4.4 If the above position is not attainable, move the
vertical center of the head restraint to the closest detent below the
center of the head CG.
S16.3.4.5 If the head restraint has a fore and aft adjustment,
place the restraint in the forwardmost position or until contact with
the head is made, whichever occurs first.
S16.3.5 Driver and passenger manual belt adjustment (for tests
conducted with a belted dummy)
S16.3.5.1 If an adjustable seat belt D-ring anchorage exists, place
it in the manufacturer's design position for a 5th percentile adult
female with the seat in the position specified in S16.2.10.3.
S16.3.5.2 Place the Type 2 manual belt around the test dummy and
fasten the latch.
S16.3.5.3 Ensure that the dummy's head remains as level as
possible, as specified in S16.3.2.1.9 and S16.3.2.1.10 and S16.3.3.1.9
and S16.3.3.1.10.
S16.3.5.4 Remove all slack from the lap belt. Pull the upper torso
webbing out of the retractor and allow it to retract; repeat this
operation four times. Apply a 9 N (2 lbf) to 18 N (4 lbf) tension load
to the lap belt. If the belt system is equipped with a tension-
relieving device, introduce the maximum amount of slack into the upper
torso belt that is recommended by the manufacturer. If the belt system
is not equipped with a tension-relieving device, allow the excess
webbing in the shoulder belt to be retracted by the retractive force of
the retractor.

S22.4.1 Each vehicle that is certified as complying with S21.4
shall meet the following test requirements with the 49 CFR part 572,
subpart P 3-year-old child dummy in both of the following positions:
Position 1 (S22.4.2) and Position 2 (S22.4.3).
S22.4.1.1 Locate and mark a point on the front of the dummy's chest
jacket on the midsaggital plane which is 114 mm (4.5 in) 3 mm ( 0.1 in) along the surface
of the skin from the top of the skin at the neck line. This is referred
to as ``Point 1.''
S22.4.1.2 Locate the vertical plane parallel to the vehicle
longitudinal centerline through the geometric center of the opening
through which the right front air bag deploys into the occupant
compartment. This is referred to as ``Plane D.''
S22.4.1.3 Locate the horizontal plane through the geometric center
of the opening through which the right front air bag deploys into the
occupant compartment. This is referred to as ``Plane C.''
S22.4.2 Position 1 (chest on instrument panel).
S22.4.2.1 If a seat is adjustable in the fore and aft and/or
vertical directions, move the seat to the rear-most seating position
and full-down height adjustment. If the seat cushion adjusts fore and
aft, independent of the entire seat, adjust the seat cushion to the
full-rearward position. If the seat back is adjustable, place the seat
back at the manufacturer's nominal design seat back angle for a 50th
percentile adult male as specified in S8.1.3 of FMVSS No. 208. Position
any adjustable parts of the seat that provide additional support so
that they are in the lowest or most open adjustment position. If
adjustable, set the head restraint in the lowest position.
S22.4.2.2 Place the dummy in the front passenger seat such that:
S22.4.2.2.1 The midsagittal plane is coincident with Plane D.
S22.4.2.2.2 The legs are initially vertical to the floor pan. The
legs and thighs shall be adjusted to the extent necessary for the head/
torso to contact the instrument panel as specified in S22.4.2.3.
S22.4.2.2.3 The upper arms are parallel to the torso and the hands
are in contact with the thighs.
S22.4.2.3 Without changing the seat position and with the dummy's
thorax instrument cavity rear face vertical, move the dummy forward
until the dummy head/torso contacts the instrument panel. If the dummy
loses contact with the seat cushion because of the forward movement,
maintain the height of the dummy and the angle of the thigh with
respect to the torso. Once contact is made, raise the dummy vertically
until Point 1 lies in Plane C. If the dummy's head contacts the
windshield and keeps Point 1 from
[[Page 3849]]
reaching Plane C, lower the dummy until there is no more than 5 mm (0.2
in) clearance between the head and the windshield. (The dummy shall
remain in contact with the instrument panel while being raised or
lowered, which may change the dummy's fore-aft position.)
S22.4.2.4 If possible, position the legs of the dummy so that the
legs are vertical and the feet rest flat on the floor pan of the
vehicle. If the positioning against the instrument panel does not allow
the feet to be on the floor pan, the feet shall be parallel to the
floor pan.
S22.4.2.5 If necessary, material with a maximum breaking strength
of 311 N (70 lb) and spacer blocks may be used to support the dummy in
position. The material should support the torso rather than the head.
Support the dummy so that there is minimum interference with the full
rotational and translational freedom for the upper torso of the dummy
and the material does not interfere with the air bag.
S22.4.3 Position 2 (head on instrument panel).
S22.4.3.1 Place the passenger seat in the full rearward seating
position. Place the seat back at the manufacturer's nominal design seat
back angle for a 50th percentile adult male as specified in S8.1.3 of
FMVSS No. 208. If adjustable in the vertical direction, place the seat
in the mid-height position. If the seat cushion adjusts fore and aft,
independent of the entire seat, adjust the seat cushion to the full
rearward position. Position any adjustable parts of the seat that
provide additional support so that they are in the lowest or most open
adjustment position. If adjustable, set the head restraint in the
lowest position.
S22.4.3.2 Place the dummy in the front passenger seat such that:
S22.4.3.2.1 The midsagittal plane is coincident with Plane D.
S22.4.3.2.2 The legs are vertical to the floor pan, the back of the
legs are in contact with the seat cushion, and the dummy's thorax
instrument cavity rear face is vertical. If it is not possible to
position the dummy with the legs in the prescribed position, rotate the
legs forward until the dummy is resting on the seat with the feet
positioned flat on the floor pan, and the back of the legs are in
contact with the front of the seat cushion. Set the transverse distance
between the longitudinal centerlines at the front of the dummy's knees
at 86 to 91 mm (3.4 to 3.6 in), with the thighs and the legs of the
dummy in vertical planes.
S22.4.3.2.3 The upper arms are parallel to the torso and the hands
are in contact with the thighs.
S22.4.3.3 Move the seat forward, while maintaining the thorax
instrument cavity rear face orientation until any part of the dummy
contacts the vehicle's instrument panel.
S22.4.3.4 If dummy contact has not been made with the vehicle's
instrument panel at the full forward seating position of the seat,
slide the dummy forward until contact is made. Maintain the thorax
instrument cavity rear face vertical orientation, the height of the
dummy, and the angle of the thigh with respect to the horizontal.
S22.4.3.5 If head/torso contact with the instrument panel has not
been made, maintain the angle of the thighs with respect to the
horizontal while applying a force towards the front of the vehicle on
the spine of the dummy between the shoulder joints until the head or
torso comes into contact with the vehicle's instrument panel.
S22.4.3.6 If necessary, material with a maximum breaking strength
of 311 N (70 lb) and spacer blocks may be used to support the dummy in
position. The material should support the torso rather than the head.
Support the dummy so that there is minimum interference with the full
rotational and translational freedom for the upper torso of the dummy
and the material does not interfere with the air bag.
S22.4.4 Deploy the right front outboard frontal air bag system. If
the frontal air bag system contains a multistage inflator, the vehicle
shall be able to comply with the injury criteria at any stage or
combination of stages or time delay between successive stages that
could occur in a rigid barrier crash test at or below 26 km/h (16 mph),
under the test procedure specified in S22.5.
S22.5 Test procedure for determining stages of air bag systems
subject to low risk deployment (low speed crashes) test requirement.
S22.5.1 The test described in S22.5.2 shall be conducted with an
unbelted 50th percentile adult male test dummy in the driver seating
position according to S8 of FMVSS No. 208 as it applies to that seating
position and an unbelted 5th percentile adult female test dummy either
in the right front seating position according to S16 as it applies to
that seating position or at any fore-aft seat position on the passenger
side.
S22.5.2 Impact the vehicle traveling longitudinally forward at any
speed, up to and including 26 km/h (16 mph) into a fixed rigid barrier
that is perpendicular 5 degrees to the line of
travel of the vehicle under the applicable conditions of S8 and S10 of
FMVSS No. 208, and S16 of this standard excluding S10.7, S10.8 and
S10.9 of FMVSS No. 208 and S16.3.5 of this standard.
S22.5.3 Determine which inflation stage or combination of stages
are fired and determine the time delay between successive stages. That
stage or combination of stages, with time delay between successive
stages, shall be used in deploying the air bag when conducting the low
risk deployment tests described in S22.4, S24.4, and S26.
S22.5.4 If the air bag does not deploy in the impact described in
S22.5.2, the low risk deployment tests described in S22.4, S24.4, and
S26 shall be conducted with all stages using the maximum time delay
between stages.

S24.2 Static tests of automatic suppression feature which shall
result in deactivation of the passenger air bag. Each vehicle that is
certified as complying with S23.2 of FMVSS No. 208 shall meet the
following test requirements.
S24.2.1 Except as provided in S24.2.2, conduct all tests as
specified in S22.2, except that the 49 CFR part 572 subpart N 6-year-
old child dummy shall be used.
S24.2.2 Exceptions. The tests specified in the following paragraphs
of S22.2 need not be conducted: S22.2.1.5, S22.2.2.3, S22.2.2.5,
S22.2.2.6, S22.2.2.7, and S22.2.2.8.
S24.2.3 Sitting back in the seat and leaning on the right front
passenger door.
(a) Position the dummy in the seated position and place the dummy
in the right front outboard seat. For bucket seats, position the
midsagittal plane of the dummy vertically such that it coincides with
the longitudinal center line of the seat cushion. For bench seats,
position the midsagittal plane of the dummy vertically and parallel to
the vehicle's longitudinal centerline and the same distance from the
longitudinal centerline of the vehicle as the center of the steering
wheel.
(b) Place the dummy's back against the seat back and rest the
dummy's thighs on the seat cushion.
(c) Allow the legs and feet of the dummy to extend off the surface
of the seat. If this positioning of the dummy's legs is prevented by
contact with the instrument panel, move the seat rearward to the next
detent that provides clearance. If the seat is a power seat, move the
seat rearward, while assuring that there is a maximum of 5 mm (0.2 in)
distance between the vehicle interior and the part of the dummy that
was in contact with the vehicle interior.
(d) Rotate the dummy's upper arms toward the seat back until they
make contact.
(e) Rotate the dummy's lower arms down until they contact the seat.
(f) Close the vehicle's passenger-side door and then start the
vehicle engine or place the ignition in the ``on'' position, whichever
will turn on the suppression system.
(g) Push against the dummy's left shoulder to lean the dummy
against the door; close all remaining doors.
(h) Wait 10 seconds, then check whether the air bag is deactivated.
S24.3 Static tests of automatic suppression feature which shall
result in activation of the passenger air bag system.
S24.3.1 Each vehicle certified to this option shall comply in tests
conducted with the right front outboard seating position at the full
rearward seat track position, the middle seat track position, and,
subject to S16.3.3.1.8, the full forward seat track position. All tests
are conducted with the seat height, if adjustable, in the mid-height
position.
S24.3.2 Place a 49 CFR part 572 subpart O 5th percentile adult
female test dummy at the right front outboard seating position of the
vehicle, in accordance with procedures specified in S16.3.3 of this
standard, except as specified in S24.3.1. Do not fasten the seat belt.
S24.3.3 Start the vehicle engine or place the ignition in the
``on'' position, whichever will turn on the suppression system, and
then close all vehicle doors.
S24.3.4 Wait 10 seconds, then check whether the air bag system is
activated.
S24.4 Low risk deployment tests.
S24.4.1 Each vehicle that is certified as complying with S23.4 of
FMVSS No. 208 shall meet the following test requirements with the 49
CFR part 572 subpart N 6-year-old child dummy in both of the following
positions: Position 1 (S24.4.2) or Position 2 (S24.4.3).
S24.4.1.1 Locate and mark a point on the front of the dummy's chest
jacket on the midsagittal plane which is 139 mm (5.5 in) 3 mm ( 0.1 in) along the surface
of the skin from the top of the skin at the neckline. This is referred
to as ``Point 1.''
S24.4.1.2 Locate the vertical plane parallel to the vehicle
longitudinal centerline through the geometric center of the opening
through which the right front air bag deploys into the occupant
compartment. This is referred to as ``Plane D.''
S24.4.1.3 Locate the horizontal plane through the geometric center
of the opening through which the right front air bag deploys into the
occupant compartment. This is referred to as ``Plane C.''
S24.4.2 Position 1 (chest on instrument panel).
S24.4.2.1 If a seat is adjustable in the fore and aft and/or
vertical directions, move the seat to the rearmost seating position and
full down height adjustment. If the seat cushion adjusts fore and aft,
independent of the entire seat, adjust the seat cushion to the full
rearward position. If the seat back is adjustable, place the seat back
at the manufacturer's nominal design seat back angle for a 50th
percentile adult male as specified in S8.1.3. Position any adjustable
parts of the seat that provide additional support so that they are in
the lowest or most open adjustment position. Position an adjustable
head restraint in the lowest position.
S24.4.2.2 Remove the legs of the dummy at the pelvic interface.
S24.4.2.3 Place the dummy in the front passenger seat such that:
(a) The midsagittal plane is coincident with Plane D.
(b) The upper arms are parallel to the torso and the hands are next
to where the thighs would be.
(c) Without changing the seat position and with the dummy's thorax
instrument cavity rear face 6 degrees forward of the vertical, move the
dummy forward until the dummy head/torso contacts the instrument panel.
If the dummy loses contact with the seat cushion because of the forward
movement, maintain the height of the dummy while moving the dummy
forward. If the head contacts the windshield before head/torso contact
with the instrument panel, maintain the thorax instrument cavity angle
and move the dummy forward such that the head is following the angle of
the windshield until there is head/torso contact with the instrument
panel. Once contact is made, raise or lower the dummy vertically until
Point 1 lies in Plane C. If the dummy's head contacts the windshield
and keeps Point 1 from reaching Plane C, lower the dummy until there is
no more than 5 mm (0.2 in) clearance between the head and the
windshield. (The dummy shall remain in contact with the instrument
panel while being raised or lowered which may change the dummy's fore-
aft position.)
S24.4.2.4 If necessary, material with a maximum breaking strength
of 311 N
[[Page 3851]]
(70 lb) and spacer blocks may be used to support the dummy in position.
The material should support the torso rather than the head. Support the
dummy so that there is minimum interference with the full rotational
and translational freedom for the upper torso of the dummy and the
material does not interfere with the air bag.
S24.4.3 Position 2 (head on instrument panel).
S24.4.3.1 Place the passenger seat in the full rearward seating
position. Place the seat back at the manufacturer's nominal design seat
back angle for a 50th percentile adult male as specified in S8.1.3 of
FMVSS No. 208. If adjustable in the vertical direction, place the seat
in the mid-height position. If the seat cushion adjusts fore and aft,
independent of the entire seat, adjust the seat cushion to the full
rearward position. Position any adjustable parts of the seat that
provide additional support so that they are in the lowest or most open
adjustment position. Position an adjustable head restraint in the
lowest position.
S24.4.3.2 Place the dummy in the front passenger seat such that:
(a) The midsagittal plane is coincident with Plane D.
(b) The legs are perpendicular to the floor pan, the back of the
legs are in contact with the seat cushion, and the dummy's thorax
instrument cavity rear face is 6 degrees forward of vertical. If it is
not possible to position the dummy with the legs in the prescribed
position, rotate the legs forward until the dummy is resting on the
seat with the feet positioned flat on the floor pan and the back of the
legs are in contact with the front of the seat cushion. Set the
transverse distance between the longitudinal centerlines at the front
of the dummy's knees at 112 to 117 mm (4.4. to 4.6 in), with the thighs
and the legs of the dummy in vertical planes.
(c) The upper arms are parallel to the torso and the hands are in
contact with the thighs. S24.4.3.3 Move the seat forward, while
maintaining the thorax instrument cavity rear face orientation until
any part of the dummy contacts the vehicle's instrument panel.
S24.4.3.4 If dummy contact has not been made with the vehicle's
instrument panel at the full forward seating position of the seat,
slide the dummy forward on the seat until contact is made. Maintain the
thorax instrument cavity rear face orientation, the height of the
dummy, and the angle of the thigh with respect to the horizontal.
S24.4.3.5 If head/torso contact has not been made with the
instrument panel, maintain the angle of the thighs with respect to the
horizontal while applying a force towards the front of the vehicle on
the spine of the dummy between the shoulder joints until the head/torso
comes into contact with the vehicle's instrument panel.
S24.4.3.6 If necessary, material with a maximum breaking strength
of 311 N (70 lb) and spacer blocks may be used to support the dummy in
position. Material should support the torso rather than the head.
Support the dummy so that there is minimum interference with the full
rotational and translational freedom for the upper torso of the dummy
and the material does not interfere with the air bag.
S24.4.4 Deploy the right front outboard frontal air bag system. If
the frontal air bag system contains a multistage inflator, the vehicle
shall be able to comply with the injury criteria at any stage or
combination of stages and at any time delay between successive stages
that could occur in a rigid barrier crash at speeds up to 26 km/h (16
mph) under the test procedure specified in S22.5.
S25 [Reserved] See Sec. 571.208, S25.
S26 Procedure for low risk deployment tests of driver air bag.
S26.1 Each vehicle that is certified as complying with S25.3 of
FMVSS No. 208 shall meet the requirements of S25.3 and S25.4 with the
49 CFR part 572 subpart O 5th percentile adult female dummy in both of
the following positions: Driver position 1 (S26.2) and Driver position
2 (S26.3).
S26.2 Driver position 1 (chin on module).
S26.2.1 Adjust the steering controls so that the steering wheel hub
is at the geometric center of the locus it describes when it is moved
through its full range of driving positions. If there is no setting at
the geometric center, position it one setting lower than the geometric
center. Set the rotation of the steering wheel so that the vehicle
wheels are pointed straight ahead.
S26.2.2 Locate the vertical plane parallel to the vehicle
longitudinal axis which passes through the geometric center of the
opening through which the driver air bag deploys into the occupant
compartment. This is referred to as ``Plane E.''
S26.2.3 Place the seat in the full rearward seating position. If
adjustable in the vertical direction, place the seat in the mid-height
position. If the seat cushion adjusts fore and aft, independent of the
entire seat, adjust the seat cushion to the full rearward position. If
the seat back is adjustable, place the seat back at the manufacturer's
nominal design seat back angle for a 50th percentile adult male as
specified in S8.1.3 of FMVSS No. 208. If the seat cushion contains an
independent seat cushion angle adjustment mechanism, adjust the seat
cushion angle to the middle of the range of seat cushion angles.
Position any adjustable parts of the seat that provide additional
support so that they are in the lowest or most open adjustment
position. Position an adjustable head restraint in the lowest position.
S26.2.4 Place the dummy in the driver's seat such that:
S26.2.4.1 The midsagittal plane is coincident with Plane E.
S26.2.4.2 The legs are perpendicular to the floor pan and the back
of the legs are in contact with the seat cushion. The legs may be
adjusted if necessary to achieve the final head position.
S26.2.4.3 The dummy's thorax instrument cavity rear face is 6
degrees forward (toward the front of the vehicle) of the steering wheel
angle (i.e., if the steering wheel angle is 25 degrees from vertical,
the thorax instrument cavity rear face angle is 31 degrees).
S26.2.4.4 The initial transverse distance between the longitudinal
centerlines at the front of the dummy's knees is 160 to 170 mm (6.3 to
6.7 in), with the thighs and legs of the dummy in vertical planes.
S26.2.4.5 The upper arms are parallel to the torso and the hands
are in contact with the thighs.
S26.2.5 Maintaining the spine angle, slide the dummy forward until
the head/torso contacts the steering wheel.
S26.2.6 While maintaining the spine angle, adjust the height of the
dummy so that the bottom of the chin is in the same horizontal plane as
the highest point of the air bag module cover (dummy height can be
adjusted using the seat height adjustments and/or spacer blocks). If
the seat prevents the bottom of the chin from being in the same
horizontal plane as the module cover, adjust the dummy height to as
close to the prescribed position as possible.
S26.2.7 If necessary, material with a maximum breaking strength of
311 N (70 lb) and spacer blocks may be used to support the dummy in
position. The material should support the torso rather than the head.
Support the dummy so that there is minimum interference with the full
rotational and translational freedom for the upper torso of the dummy
and the material does not interfere with the air bag.
S26.3 Driver position 2 (chin on rim).
S26.3.1 Place the seat in the full rearward seating position. If
adjustable in the vertical direction, place the seat in the mid-height
position. If the seat
[[Page 3852]]
cushion adjusts fore and aft, independent of the entire seat, adjust
the seat cushion to the full rearward position. If the seatback is
adjustable, place the seat back at the manufacturer's nominal design
seat back angle for a 50th percentile adult male as specified in S8.1.3
of FMVSS No. 208. If the seat cushion contains an independent seat
cushion angle adjustment mechanism, adjust the seat cushion angle to
the middle of the range of seat cushion angles. Position any adjustable
parts of the seat that provide additional support so that they are in
the lowest or most open adjustment position. Position an adjustable
head restraint in the lowest position.
S26.3.2 Adjust the steering controls so that the steering wheel hub
is at the geometric center of the locus it describes when it is moved
through its full range of driving positions. If there is no setting at
the geometric center, position it one setting lower than the geometric
center. Set the rotation of the steering wheel so that the vehicle
wheels are pointed straight ahead.
S26.3.3 Locate the vertical plane parallel to the vehicle
longitudinal axis which passes through the geometric center of the
opening through which the driver air bag deploys into the occupant
compartment. This is referred to as ``Plane E.''
S26.3.4 Place the dummy in the driver's seat position such that:
S26.3.4.1 The midsagittal plane is coincident with Plane E.
S26.3.4.2 The legs are perpendicular to the floor pan and the back
of the legs are in contact with the seat cushion. The legs may be
adjusted if necessary to achieve the final head position.
S26.3.4.3 The dummy's thorax instrument cavity rear face is 6
degrees forward (toward the front of the vehicle) of the steering wheel
angle (i.e., if the steering wheel angle is 25 degrees from vertical,
the thorax instrument cavity rear face angle is 31 degrees).
S26.3.4.4 The initial transverse distance between the longitudinal
centerlines at the front of the dummy's knees is 160 to 170 mm (6.3 to
6.7 in), with the thighs and legs of the dummy in vertical planes.
S26.3.4.5 The upper arms are parallel to the torso and the hands
are in contact with the thighs.
S26.3.5 Maintaining the spine angle, slide the dummy forward until
the head/torso contacts the steering wheel.
S26.3.6 While maintaining the spine angle, position the dummy so
that a point on the chin 40 mm below the center of the mouth (chin
point) is in contact with the rim of the uppermost portion of the
steering wheel. If the dummy's head contacts the vehicle windshield or
upper interior before the prescribed position can be obtained, lower
the dummy until there is no more than 5 mm (0.2 in) clearance between
the vehicle's windshield or upper interior, as applicable.
S26.3.7 If the steering wheel can be adjusted so that the chin
point can be in contact with the rim of the uppermost portion of the
steering wheel, adjust the steering wheel to that position and readjust
the spine angle to coincide with the steering wheel angle. Position the
dummy so that the chin point is in contact with the rim of the
uppermost portion of the steering wheel.
S26.3.8 If necessary, material with a maximum breaking strength of
311 N (70 lb) and spacer blocks may be used to support the dummy in
position. The material should support the torso rather than the head.
Support the dummy so that there is minimum interference with the full
rotational and translational freedom for the upper torso of the dummy
and the material does not interfere with the air bag.
S26.4 Deploy the left front outboard frontal air bag system. If the
air bag system contains a multistage inflator, the vehicle shall be
able to comply with the injury criteria at any stage or combination of
stages or time delay between successive stages that could occur in a
rigid barrier crash at speeds up to 26 km/h (16 mph) under the test
procedure specified in S22.5.
