ABSTRACT:
A seat belt retractor includes a housing having laterally spaced first and second housing walls and a belt reel journaled for rotation by a reel shaft extending between the housing walls. A ratchet plate is attached to each end of the reel. A lock bar extends between the housing side walls and has locking teeth at the ends thereof adapted for selective engagement with the ratchet plates upon pivotal movement of the lock bar toward the ratchet plate. A release member is provided to forcibly disengage the lock bar from engagement with the ratchet plates and includes laterally spaced first and second abutment portions which respectively extend between the ratchet plate and the adjacent housing wall to overlie the locking teeth of the lock bar in spaced relation therefrom. A manually actuated release lever moves the release member into simultaneous engagement with the locking teeth at both ends of the lock bar to forcibly disengage the lock bar from engagement with the ratchet plates to permit belt unwinding rotation.
