SEAT BELT RETRACTOR ASSEMBLY WITH POST EMERGENCY SPOOL RELEASE ABSTRACT An emergency spool release for use with a seat belt retractor mechanism is shown wherein the seat belt mechanism includes a spool (20) for storing a belt (26) which restrains the passenger of a vehicle during an emergency. The belt, which is urged into a retracted position by a spring, is restrained in the protracted position in an emergency by the automatic engagement of a locking pawl (28) against ratchet teeth (24) found on the periphery of the spool. The automatic engagement is accomplished by an inertia locking system. To disengage the locking system after it locks, the locking pawl (28) in the seat belt mechanism of this invention is capable of a rotational motion to engage the ratchet teeth (24) under the urging of the inertia locking device and of a transverse motion under the urging of a manual unlocking device such as a lever (62) for post emergency release. The lever (62) is attached to the locking pawl (28) and spring biased into the automatic position. Actuation of a lever either manually or by a second lever mechanism causes the transverse motion of the locking pawl to unlock the seat belt mechanism in the post emergency condition.
