TITLE: FMVSS INTERPRETATION

TEXT: This is in reply to your letter of June 28, 1972, in which you requested formal confirmation of the interpretation of S4.3(c) of Motor Vehicle Safety Standard No. 209 given you informally on June 22.

The requirements of S4.3(c) apply to bolts used to secure the pelvic restraint of a seat belt assembly. They do not apply to bolts used to secure the upper torso restraint. Bolts for the upper torso restraint are therefore regulated with respect to their strength only by the assembly performance requirements of S4.4(b).

The reference to "shoulder bolts" in S4.3(c) relates to the design of the bolt and not to the manner of its use. Pelvic restraints are often attached to the vehicle by such bolts, hence the reference to them.
