Sec. 571.208 Standard No. 208, Occupant Crash Protection.
* * * * *
S7.1.1.5 Passenger cars, and trucks, buses, and multipurpose
passenger vehicles with a GVWR of 10,000 pounds or less manufactured on
or after September 1, 1995 shall meet the requirements of S7.1.1.5(a),
S7.1.1.5(b) and S7.1.1.5(c).
(a) Each designated seating position, except the driver's position,
and except any right front seating position that is equipped with an
automatic belt, that is in any motor vehicle, except walk-in van-type
vehicles and vehicles manufactured to be sold exclusively to the U.S.
Postal Service, and that is forward-facing or can be adjusted to be
forward-facing, shall have a seat belt assembly whose lap belt portion
is lockable so that the seat belt assembly can be used to tightly
secure a child restraint system. The means provided to lock the lap
belt or lap belt portion of the seat belt assembly shall not consist of
any device that must be attached by the vehicle user to the seat belt
webbing, retractor, or any other part of the vehicle. Additionally, the
means provided to lock the lap belt or lap belt portion of the seat
belt assembly shall not require any inverting, twisting or otherwise
deforming of the belt webbing.
(b) If the means provided pursuant to S7.1.1.5(a) to lock the lap
belt or lap belt portion of any seat belt assembly makes it necessary
for the vehicle user to take some action to activate the locking
feature, the vehicle owner's manual shall include a description in
words and/or diagrams describing how to activate the locking feature so
that the seat belt assembly can tightly secure a child restraint system
and how to deactivate the locking feature to remove the child restraint
system.
(c) Except for seat belt assemblies that have no retractor or that
are equipped with an automatic locking retractor, compliance with
S7.1.1.5(a) is demonstrated by the following procedure:
(1) With the seat in any adjustment position, buckle the seat belt
assembly. Complete any procedures recommended in the vehicle owner's
manual, pursuant to S7.1.1.5(b), to activate any locking feature for
the seat belt assembly.
(2) Locate a reference point A on the safety belt buckle. Locate a
reference point B on the attachment hardware or retractor assembly at
the other end of the lap belt or lap belt portion of the seat belt
assembly. Adjust the lap belt or lap belt portion of the seat belt
assembly pursuant to S7.1.1.5(c)(1) as necessary so that the webbing
between points A and B is at the maximum length allowed by the belt
system. Measure and record the distance between points A and B along
the longitudinal centerline of the webbing for the lap belt or lap belt
portion of the seat belt assembly.
(3) Readjust the belt system so that the webbing between points A
and B is at any length that is 5 inches or more shorter than the
maximum length of the webbing.
(4) Apply a pre-load of 10 pounds, using the webbing tension pull
device described in Figure 5 of this standard, to the lap belt or lap
belt portion of the seat belt assembly in a vertical plane parallel to
the longitudinal axis of the vehicle and passing through the seating
reference point of the designated seating position whose belt system is
being tested. Apply the pre-load in a horizontal direction toward the
front of the vehicle with a force application angle of not less than 5
degrees nor more than 15 degrees above the horizontal. Measure and
record the length of belt between points A and B along the longitudinal
centerline of the webbing for the lap belt or lap belt portion of the
seat belt assembly while the pre-load is being applied.
(5) Apply a load of 50 pounds, using the webbing tension pull
device described in Figure 5 of this standard, to the lap belt or lap
belt portion of the seat belt assembly in a vertical plane parallel to
the longitudinal axis of the vehicle and passing through the seating
reference point of the designated seating position whose belt system is
being tested. The load is applied in a horizontal direction toward the
front of the vehicle with a force application angle of not less than 5
degrees nor more than 15 degrees above the horizontal at an onset rate
of not more than 50 pounds per second. Attain the 50 pound load in not
more than 5 seconds. If webbing sensitive emergency locking retroactive
are installed as part of the lap belt assembly or lap belt portion of
the seat belt assembly, apply the load at a rate less than the
threshold value for lock-up specified by the manufacturer. Maintain the
50 pound load for at least 5 seconds before the measurements specified
in S7.1.1.5(c)(6) are obtained and recorded.
(6) Measure and record the length of belt between points A and B
along the longitudinal centerline of the webbing for the lap belt or
lap belt portion of the seat belt assembly.
(7) The difference between the measurements recorded under
S7.1.1.5(c) (6) and (4) shall not exceed 2 inches.
(8) The difference between the measurements recorded under
S7.1.1.5(c) (6) and (2) shall be 3 inches or more.
