摘要： A seat belt retractor for use in a passive seat belt system having one of the belt ends attached to the vehicle door. A belt reel is 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 stop provided on the housing limits movement of the support link in the direction toward the toothed ratchet plate to establish the support link at a normal position wherein the pivot axis of the lockbar is situated over center with respect to the locking face of the lockbar and the pivot axis of the support link. Accordingly, whenever the inertia sensing pendulum moves the lockbar into locking engagement with the ratchet plate, the stop supports the support link and the lockbar against movement by the belt load so that the reel is locked against unwinding rotation. A manually operated handle is connected to the support link and permits the occupant to forcibly move the support link in the direction away from the stop and the ratchet plate so that the pivot axis of the lockbar is moved over center with respect to the support link pivot axis and the face of the lockbar engaging the ratchet plate. Thus, the lockbar is disengaged from locking engagement with the ratchet plate so that the belt may be unwound to terminate restraint of the occupant and permit opening movement of the door.
摘要翻译：一种用于被动安全带系统的安全带卷收器，其具有附接到车门的带端之一。皮带卷轴可旋转地安装在卷收器壳体上用于带卷绕和放卷旋转。带齿的棘轮板由卷轴承载。锁定杆枢转地安装在支撑连杆上，支撑连杆又可枢转地安装在牵开器壳体上。设置在壳体上的止动件限制支撑连杆朝向齿形棘轮板的方向的移动，以在正常位置建立支撑连杆，其中锁定杆的枢转轴线相对于锁定杆的锁定面位于中心以上，支撑链节的枢转轴线。因此，每当惯性感测摆动锁定杆与棘轮板锁定接合时，止动件支撑支撑连杆和锁定杆，防止皮带负载运动，使得卷轴被锁定以解除卷绕旋转。手动操作的手柄连接到支撑连杆并且允许乘员在远离止动件和棘轮板的方向上强制地移动支撑连杆，使得锁定杆的枢转轴线相对于支撑连杆枢轴转过中心并且锁定杆的表面接合棘轮板。因此，锁定杆脱离与棘轮板的锁定接合，使得带可以被解开以终止乘员的限制并允许门的打开移动。
