[Docket No. NHTSA-2006-23848]
RIN 2127-AJ84
Federal Motor Vehicle Safety Standards; Head Restraints
AGENCY: National Highway Traffic Safety Administration (NHTSA),
Department of Transportation (DOT).
ACTION: Final rule; partial response to petitions for reconsideration.
-----------------------------------------------------------------------
SUMMARY: This document responds, in part, to petitions for
reconsideration of the December 2004 final rule amending our head
restraints standard. The amended standard contains new requirements
applicable to head restraints voluntarily installed in rear outboard
designated seating positions. Because of the time constraints faced by
vehicle manufacturers in certifying voluntarily installed rear outboard
head restraints to the new requirements, we are bifurcating our
response. This document addresses those issues we feel are most time
sensitive. In particular, we are responding to those petitions asking
the agency to delay the application of the new requirements to
voluntarily installed rear outboard head restraints. This final rule
delays the date on which the manufacturers must comply with the
requirements applicable to head restraints voluntarily installed in
rear outboard designated seating positions from September 1, 2008 until
September 1, 2010. The remaining petitions for reconsideration will be
addressed in a separate notice.
DATES: Effective Date: The amendments made in this rule are effective
May 8, 2006.
Petitions: Petitions for reconsideration of the amendments made by
this rule must be received by April 24, 2006.
ADDRESSES: Petitions for reconsideration should refer to the docket and
notice number of this document and be submitted to: Administrator,
National Highway Traffic Safety Administration, 400 Seventh Street,
SW., Washington, DC 20590.

I. Background
On December 14, 2004, we published in the Federal Register a final
rule (December 2004 final rule) upgrading Federal Motor Vehicle Safety
Standard (FMVSS) No. 202, ``Head restraints.'' \1\ The standard, which
seeks to reduce whiplash injuries in rear collisions, was upgraded to
provide better whiplash protection for a wider range of occupants. For
front seats, the final rule established a higher minimum height
requirement, a requirement limiting the distance between the back of an
occupant's head and the occupant's head restraint (backset), as well as
a limit on the size of gaps and openings within head restraints. There
were also new requirements for height, strength, position retention,
and energy absorption. In addition, the final rule established new
requirements for head restraints voluntarily installed in rear outboard
designated seating positions, and added certain requirements specific
to rear head restraints capable of folding or retracting into a ``non-
use position'' to accommodate stowable rear seats, or to increase
rearward visibility. The upgraded provisions were designated FMVSS No.
202a.
---------------------------------------------------------------------------
\1\ See 69 FR 74848.
---------------------------------------------------------------------------
In response to the final rule, vehicle manufacturers expressed
concern that adoption of the rear seat head restraint requirements
would reduce vehicle
[[Page 12146]]
utility by interfering with or even reducing the ability to provide the
sort of folding seats currently available in ``multi-configuration''
vehicles such as vans and multipurpose passenger vehicles.
II. Petitions for Reconsideration
We received eight petitions for reconsideration of the December 14,
2004, final rule. These petitions were filed by the Alliance of
Automobile Manufacturers (Alliance), Syson-Hille and Associates (Syson-
Hille), Keiper, Johnson Controls (JC), BMW, Ford Motor Company (Ford),
and DaimlerChrysler (DCX). GM filed comments in support of the Alliance
petition, and Kongsberg Automotive (Kongsberg) submitted a late
petition.
The petitions from the Alliance, Syson-Hille, Keiper, JC, BMW,
Ford, DCX and Kongsberg requested revisions to the final rule in the
areas of backset measurement and limit, height measurement and limit,
clearance between the head restraint and roofline, measurement of the
gap between the head restraint and seat back, retention test procedure,
dynamic test alternative, energy absorption tests, and owner's manual
requirements. Many petitioners also argued for delaying the September
1, 2008, effective date for all new requirements. Our response to these
particular issues will be addressed in a subsequent notice.
The remaining petitions for reconsideration pertained to the
requirements for optional rear head restraints. The Alliance argued
that recently many new vehicles have been designed such that the rear
seats retract into the floor. The head restraints on these seats can be
lowered to a position nearly flush with the top of the seat back,
allowing the seat to be stowed without head restraint removal. The
Alliance argued that the new requirements applicable to folding rear
head restraints are so stringent that it would be impossible for
manufacturers to provide rear head restraints that can retract enough
to allow flat-folding rear seats. Ford argued that strong customer
demand for vehicle functionality requires rear seats with folding or
otherwise stowable seats and stated that the current requirements are
not reasonable, necessary or practicable.
The Alliance, BMW, and DCX requested that the manually stowed non-
use position compliance option originally in the NPRM be reinstated
except that the required torso angle change should be no more than 5
degrees. The Alliance commented that the final rule prohibits designs
that meet the 10-degree torso angle requirement from the NPRM even
though those designs could provide occupants with an obvious physical
cue that the head restraint is not properly positioned. The Alliance
added that design work on seats that meet the NPRM criteria are well
underway by some companies, and those companies would experience
hardship if those designs are prohibited by the final rule.
The Alliance petitioned the agency to allow non-use positions of
less than 700 mm, and in-use adjustment positions between 700 and 750
mm. In effect, this petition is asking the agency to lower the minimum
height requirement for rear seat head restraints from 750 mm to 700 mm,
while maintaining that the head restraint be capable of reaching 750
mm. In addition, the Alliance requested that the clearance between the
head restraint and roofline be clarified to ``inside of the
headliner.'' The Alliance commented that a clearance of at least 50 mm,
with the roof in place, is needed in the rear seat outboard locations
to permit convertible roof mechanisms to operate freely. DCX requested
that during the roof folding process a clearance of 10 mm be permitted.
Finally, the Alliance and DCX petitioned that NHTSA modify the
effective date to require 80 percent compliance with FMVSS 202a
beginning September 1, 2008, and 100 percent beginning September 1,
2009, with carry forward credits as has been allowed in other NHTSA
rulemakings. The Alliance commented that the effective date set forth
in the final rule does not provide sufficient lead-time for design
modifications to mechanisms that allow for conversion of passenger
compartments to cargo areas. The Alliance further stated that certain
vehicle models that are past final design release will continue in
production beyond the September 1, 2008, effective date, but would
require extensive changes to comply with the mandatory FMVSS 202a
requirements. DCX commented that the phase-in would alleviate the need
for design and development activity to occur all at once, and
potentially eliminate short seat production runs.
GM \2\ submitted additional comments on the final rule requesting
additional lead-time to permit development of the Global Technical
Regulation on head restraints. GM argued that without relief from the
existing requirements, an unintended consequence of the final rule
would be that manufacturers may opt not to install head restraints in
rear seats instead of installing head restraints that present stowage
incompatibility or visibility concerns. The Alliance \3\ submitted
additional comments in support of GM's position.

III. Response to Rear Seat Lead-time Issues in Petitions
This document responds only to those portions of the petitions
regarding the lead-time for manufacturers to meet the requirements for
head restraints voluntarily installed in rear outboard seating
positions. Resolution of the remaining petition for reconsideration
issues will be addressed in a subsequent notice.
We agree that manufacturers need additional time to design manually
retractable rear head restraints that meet the new performance
requirements. In meetings with DCX \4\, Ford \5\, and GM \6\, the
petitioners stated that the final rule adversely impacts the design of
head restraints for stowable seating. For example, DCX argued that
saddle-type (shingle-type) head restraints, often used on stowable
folding seats, would not meet the minimum height requirement when
adjusted to their lowest position, and would not meet the non-use
position criteria. Ford argued that a flat vehicle floor is a key
requirement of consumers that would be affected if the final rule were
not amended. GM argued that less stringent criteria with respect to
non-use positions is preferable to a situation where vehicle operators
are forced to remove the rear head restraint to fold the rear seats. GM
argued that the standard should be amended to permit seat designs that
allow consumers to keep the head restraint attached to the seat when
folding, because it will help reduce the risks of improper head
restraint installation, non-installation, and potential seat damage.

\6\ Docket number NHTSA-2004-19807-17.
---------------------------------------------------------------------------
In meetings \7\ held with the agency in August of 2005, GM proposed
several options for visual cues that a rear seat head restraint is in a
non-use position. These included a permanent label similar to that
already present in some Volvo models, and indicators that deploy only
when the head restraint is in the lowest position. GM suggested that
visual cues such as these could be employed to ensure that consumers
properly adjust rear seat head restraints for use after stowage. A
delay in the final rule is needed for the agency to fully analyze these
cues as an option.

---------------------------------------------------------------------------
[[Page 12147]]
The agency believes that a delay in the effective date of the
requirements applicable to rear head restraints would permit
development of seat designs that meet the new requirements and still
provide for stowage. It is not the agency's intent to discourage
vehicle manufacturers from offering head restraints in rear seats.
Further, because the vehicles that will become subject to the new
requirements in 2008 are either already in production or in the final
design stages, we believe that a delay is necessary at this time.
Without this action, vehicle manufacturers indicated that they would be
forced to remove rear head restraints from MY 2008 vehicles while they
are attempting to resolve the issues raised above.
We considered the option of only delaying the application of ``non-
use'' provisions for the rear seats. However, to allow a position of
non-use below 750 mm, without any limitations, is tantamount to
allowing a height lower than 750 mm. Thus, we believe a 2-year delay in
regulations for the rear seat head restraints will give manufacturers
the extra lead-time needed to address the folding rear seat packaging
issues while implementing the front seat regulations.
NHTSA believes that this delay is a reasonable change. Based on
National Analysis Sampling System (NASS) data from 2001 to 2003, the
distribution of occupants by seating position for all vehicle types
shows that 10 percent of all occupants sit in the second (or higher)
row of outboard seats. Fewer rear seat occupants are exposed to risks
in rear impacts because rear seats are much less likely to be occupied
than front seats. We note that children and small adults derive less
benefit from taller head restraints because their head center of
gravity often does not reach the height of 750 mm above the H point.\8\
Therefore, if we further refine these data to include only occupants
who are 13 years or older, the relevant percentage is reduced to
approximately 5.1 percent. Our conclusions about rear seat occupancy
are further supported by the FRIA (Final Regulatory Impact Analysis)
data, which indicate that out of a total of 272,464 annually occurring
whiplash injuries, approximately 21,429 (7.8 percent) occur to the rear
seat occupants. In sum, only a small percentage of occupants who are
tall enough to benefit from taller head restraints sit in rear outboard
seating positions. Furthermore, without this delay, manufacturers would
likely exercise the option to remove rear seat head restraints
entirely.
---------------------------------------------------------------------------
\8\ The H-point is defined by a test machine placed in the
vehicle seat (Society of Automotive Engineers (SAE) J826, July
1995). From the side, the H-point represents the pivot point between
the torso and upper leg portions of the test machine. It can be
thought of, roughly, as the hip joint of a 50th percentile male
occupant viewed laterally.
---------------------------------------------------------------------------
In light of the foregoing, NHTSA is granting an additional 2 years
for manufacturers to develop designs that comply with the voluntarily
installed rear head restraint requirements. The requirements applicable
to head restraints installed in rear outboard designated seating
positions will become effective September 1, 2010.
IV. Regulatory Analyses and Notices
A. Executive Order 12866 and DOT Regulatory Policies and Procedures
NHTSA has considered the impact of this rulemaking action under
Executive Order 12866 and the Department of Transportation's regulatory
policies and procedures. This rulemaking document was not reviewed
under E.O. 12866, ``Regulatory Planning and Review.'' Although this
document amends the agency's December 2004 final rule, which was
economically significant, NHTSA has determined that this document does
not affect the costs and benefits analysis for that final rule. Readers
who are interested in the overall costs and benefits of head restraints
are referred to the agency's Final Economic Assessment for the December
2004 FMVSS No. 202 final rule (NHTSA Docket No. 04-19807). This notice
has also been determined not to be significant under the Department's
regulatory policies and procedures. The amendments made by this
document provide some relief rather than impose additional costs on
manufacturers or consumers. Their impacts are so minimal that a full
regulatory evaluation is not merited.
B. Regulatory Flexibility Act
We have considered the effects of this rulemaking action under the
Regulatory Flexibility Act (5 U.S.C. 601 et seq.) 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 December 2004 final rule. Instead, this document delays the
effective date of some of the requirements. Small organizations and
small governmental units will not be significantly affected since the
potential cost impacts associated with this rule will not affect the
price of new motor vehicles.
C. National Environmental Policy Act
NHTSA has analyzed these amendments for the purposes of the
National Environmental Policy Act and determined that they will not
have any significant impact on the quality of the human environment.
D. Executive Order 13132 (Federalism)
The agency has analyzed this rulemaking in accordance with the
principles and criteria contained in Executive Order 13132 and has
determined that it does not have sufficient federalism implications to
warrant consultation with State and local officials or the preparation
of a federalism summary impact statement. The final rule has no
substantial effects on the States, or on the current Federal-State
relationship, or on the current distribution of power and
responsibilities among the various local officials.
E. Unfunded Mandates Reform Act
The Unfunded Mandates Reform Act of 1995 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 million annually
(adjusted for inflation with base year of 1995). While the December
2004 final rule is likely to result in over $100 million of annual
expenditures by the private sector, today's final rule makes only small
adjustments to the December 2004 rule. Accordingly, this final rule
will not result in a significant increase in cost to the private
sector.
F. Executive Order 12778 (Civil Justice Reform)
This final rule does not have any retroactive effect. Under section
49 U.S.C. 30103, whenever a Federal motor vehicle safety standard is in
effect, a state may not adopt or maintain a safety standard applicable
to the same aspect of performance which is not identical to the Federal
standard, except to the extent that the state requirement imposes a
higher level of performance and applies only to vehicles procured for
the State's use. 49 U.S.C. 30161 sets forth a procedure for judicial
review of final rules establishing, amending or revoking Federal motor
vehicle safety standards. That section does not require submission of a
petition for reconsideration or other administrative proceedings before
parties may file suit in court.
G. Paperwork Reduction Act
Under the Paperwork Reduction Act of 1995, a person is not required
to respond to a collection of information
[[Page 12148]]
by a Federal agency unless the collection displays a valid OMB control
number. This rule does not establish any new information collection
requirements.
H. 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.
I. Plain Language
Executive Order 12866 requires each agency to write all rules in
plain language. This final rule will not significantly impact the
complexity of FMVSS 202.
J. Executive Order 13045
Executive Order 13045 applies to any rule that: (1) Is determined
to be economically significant as defined under E.O. 12866, and (2)
concerns an environmental, health or safety risk that NHTSA has reason
to believe may have a disproportionate effect on children. If the
regulatory action meets both criteria, we must evaluate the
environmental health or safety effects of the planned rule on children,
and explain why the planned regulation is preferable to other
potentially effective and reasonably feasible alternatives considered
by us. This rulemaking does not involve decisions based on health risks
that disproportionately affect children.
K. National Technology Transfer and Advancement Act
Section 12(d) of the National Technology Transfer and Advancement
Act (NTTAA) requires NHTSA to evaluate and use existing voluntary
consensus standards \9\ in its regulatory activities unless doing so
would be inconsistent with applicable law (e.g., the statutory
provisions regarding NHTSA's vehicle safety authority) or otherwise
impractical. In meeting that requirement, we are required to consult
with voluntary, private sector, consensus standards bodies. Examples of
organizations generally regarded as voluntary consensus standards
bodies include the American Society for Testing and Materials (ASTM),
the Society of Automotive Engineers (SAE), and the American National
Standards Institute (ANSI). If NHTSA does not use available and
potentially applicable voluntary consensus standards, we are required
by the Act to provide Congress, through OMB, an explanation of the
reasons for not using such standards.
---------------------------------------------------------------------------
\9\ Voluntary consensus standards are technical standards
developed or adopted by voluntary consensus standards bodies.
Technical standards are defined by the NHTSA as ``a performance-
based or design specific technical specifications and related
management systems practices. They pertain to products and
processes, such as size, strength, or technical performance of a
product, process or material.''
---------------------------------------------------------------------------
The agency is not aware of any new voluntary consensus standards
addressing the changes made to the December 2004 final rule as a result
of this final rule.
