Abstract: INERTIA RELEASE FOR BELT RETRACTOR WINDING PREVENTION MECHANISM In a seat belt retractor winding prevention mechanism, the winding prevention pawl is mounted upon a collapsible support mechanism which is collapsed by the onset of a sensed vehicle deceleration condition so that force imposed on the pawl by the windup spring shifts the pawl against a cam which moves the pawl axially out of engagement with the ratchet teeth carried by the reel to thereby release the winding prevention mechanism so that the windup spring will rewind the belt to a taut condition about the occupant.
