ABSTRACT:
A lock-up mechanism for a vehicle sensitive automotive seat belt retractor having a shuttle displaceable with the winding and unwinding of the seat belt webbing from the retractor's spool and a lock pawl activated by the shuttle to pivot the retractor's lock bar into engagement with the retractor's lock bar. The lock pawl is pivoted to a reset position by the shuttle disengaging the lock pawl from the retractor's lock bar permitting the webbing to be extracted from the retractor's spool in a normal manner. An overcenter spring holds the lock pawl in either the locked position pivoting the lock bar into engagement with the retractor's ratchet wheel or the reset position with the lock pawl disengaged from the lock bar.
