ABSTRACT:
A seat belt retractor includes a rotatable spool around which a seat belt is wound for storage and from which the seat belt is unwound for use. A ratchet wheel is fixed to the spool. A locking pawl is movable between a disengaged position spaced from the ratchet wheel to an engaged position engaging the ratchet wheel to prevent rotation of the spool in a belt unwinding direction. A cinch mechanism includes an actuator member which is movable from a retracted position to an extended position to move the locking pawl from the disengaged position to the engaged position. A web follower or sensor member is engageable with the seat belt and is movable in response to winding and unwinding of the seat belt. As the seat belt is unwound, the web follower pivots from a first position to a second position. As this occurs, an overcenter spring pivots the actuator member from the retracted position to the extended position, with a snap action, to move the locking pawl into engagement with the ratchet wheel.
