    • 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.
    • 一种设备(20,100),包括:从动齿轮(102),其可操作地连接到牵开器(20)的卷轴,以沿着缩回方向旋转所述卷轴(24),从而使安装带(31)卷绕在其上以缩回 ; 具有靠近齿轮的平坦出口端(302)的弓形管(108) 柔性链条(130),其在管内可移动,具有最初保持与第一齿轮不接合的前端(134a)并被推入与第一齿轮接合以引起其相转动; 活塞(600),用于将链条(130)推动与齿轮接合,从而使齿轮旋转并且在链条退出管的出口端之后用于保持链条的机构。
