ABSTRACT:
A safety belt system having separate lap and shoulder belts. The belts are attached to a double spool belt retraction mechanism which is spring biased to retract the belts. Each spool has associated with it a ratchet wheel and a pawl movable into engagement with the ratchet wheel to prevent extension of the associated belt under certain conditions. A pendulum type inertial member is associated with each pawl and is operable under certain conditions of vehicle acceleration and attitude to move the associated pawl into engagement with the related ratchet wheel. The system includes a belt tension eliminating mechanism which prevents retraction of the shoulder belt under certain operating conditions and a member associated with each pawl which prevents the pawl from rattling under certain operating conditions.
