    摘要: An apparatus (20, 100) comprising: a driven gear (102) operatively linked to a spool of a retractor (20) to rotate the spool (24) in a direction of retraction to cause a seat belt (31) wound thereabout to retract; an arcuate tube (108) having a flat exit end (302) proximate the gear; a flexible chain (130), moveable within the tube, having a front end (134a) initially maintained out of engagement with the first gear and pushed into engagement with the first gear to cause same to rotate; a piston (600) for pushing the chain (130) into engagement with the gear thereby causing the gear to rotate and catching mechanism for retaining the chain after it has exited the exit end of the tube.
