A seat belt retractor has a belt reel rotatably mounted on the retractor housing for belt winding and unwinding rotation. A toothed ratchet plate is carried by the reel. A lockbar is pivotally mounted on a support link which is in turn pivotally mounted on the retractor housing. A latch lever is pivotally mounted on the housing and engages the support link to support the support link at a normal position establishing the lockbar in proximity with the ratchet plate for selective movement between locking and unlocking positions relative the ratchet plate. A handle or the like is associated with the latch lever whereby the occupant may forcibly disengage the latch lever from latching engagement with the support link thereby permitting the seat belt load imposed on the support link by the lockbar to pivot the support link away from the ratchet plate and thereby move the lockbar from the locking position to unlock the reel for a belt unwinding rotation. Springs are associated with the lockbar, the support link, and the latch lever to restore their normal positions.
