ABSTRACT:
A seat belt retractor (10) has a rotatable spool (50) on which seat belt webbing (16) is wound. Rotation of the spool (50) results in rotation of an actuator gear (170) which drives an actuator ring (200). The actuator gear (170) and actuator ring (200) control movement of a cinch lever (130) to an actuated position to move a lock pawl (100) into engagement with a ratchet wheel (90) to block rotation of the spool (50) in a belt withdrawal direction (58). When all the belt webbing (16) is wound on the spool (50), a blocking member (230) on the actuator ring (200) moves the cinch lever (130) against a vehicle deceleration sensor lever (118) to minimize rattling of the sensor lever and of an inertia mass (112). A projection (216) on the actuator ring (200) ensures proper movement of the cinch lever (130) from the actuator ring (200) onto a cam surface (194) of the actuator gear (170). A spring (182) on the actuator gear (170) allows the actuator gear to assume a correctly timed rotational position when the belt webbing (16) is fully withdrawn from the spool (50).
