Abstract: An improved safety apparatus (10) is used in association with a belt (16) which restrains movement of an occupant of a vehicle. The belt (16) is taken up by and paid out from a retractor assembly (22). Upon the occurrence of vehicle deceleration greater than a predetermined deceleration, a solenoid assembly (132) operates a clamp assembly (28) to grip the belt (16) and prevent paying out of the belt. In one embodiment of the invention, the retractor assembly (22) includes a sensor assembly (54) which operates a retainer assembly (56) to prevent withdrawal of the belt from the retractor assembly when the deceleration of the vehicle is in excess of a predetermined deceleration. The sensor assembly (54) is mounted on a movable carriage (32) in the retractor assembly (22). Although the clamp assembly (28) and the retractor assembly (22) may be used in many different locations in a vehicle, they are advantageously located on the back (24) of a vehicle seat (12).

Abstract: A vehicle seat belt retractor (10) has a spool (20) on which seat belt webbing (26) is wound. An externally-toothed ratchet wheel (50) is rotatable with the spool (20) in a belt withdrawal direction (22). A first pawl (70) is supported on a housing (12) for pivotal movement about a first axis (72) into engagement with the ratchet wheel (50) to block rotation of the ratchet wheel (50) in the belt withdrawal direction (22). An inertia member (62) supported on the housing (12) is movable in response to vehicle deceleration greater than a predetermined deceleration to pivot the first pawl (70) into engagement with the ratchet wheel (50) and thereby block rotation of the ratchet wheel (50) and the spool (20) in the belt withdrawal direction (22). A second pawl (90) is supported on the housing (12) for pivotal movement relative to the ratchet wheel (50) about a second axis (92) spaced from the first axis (72).
