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.
