A seat belt retractor has a seat belt shaft and a control cam mounted thereon, and an electrically actuatable locking device (100) which stops the control cam (21) relative to the seat belt shaft (20) by engagement of the locking lever (2) into the tooth system (26) of the control cam (21), the locking lever (2) has a first arm (16) and thus forces a pawl to perform a movement in which the pawl is fixed to the vehicle and locks the seat belt shaft in the pull-out direction by means of a tooth system which engages with the seat belt retractor, and wherein the locking lever (2) has a lever arm (22) which projects outwards from the first arm (16) and which engages with the first arm (16) and thus forces the pawl to perform a movement in which the tooth system is fixed to the vehicle and locks the seat belt shaft in the pull-out direction. The locking lever (2) has a lever arm (23), on which a first end of a first spring (4) acts, which preloads the locking lever (2) into a position in which the locking lever engages with a locking tip (25) arranged at the end of the locking arm (23) into the tooth system (26) of the control cam (21). Furthermore, a projection (200) is provided on the housing (1) of the locking device, which projection is shaped such that the first spring (4) abuts against the projection independently of the position of the locking lever (2) and is transversely preloaded with respect to the spring force exerted on the lever arm (22).

    一种座椅安全带卷收器,该座椅安全带卷收器具有座椅安全带轴和安装在其上的控制凸轮,以及可电致动的闭锁装置(100),该可电致动的闭锁装置(100)通过该闭锁杠杆(2)接合至该控制凸轮(21)的该齿系统(26)中来使该控制凸轮(21)相对于该座椅安全带轴(20)停止,并且因此迫使锁定爪执行运动,在该运动中该锁定爪通过以接合至该座椅安全带卷收器的齿系统中,该齿系统固定至该车辆,并且在拉出方向上闭锁该座椅安全带轴,其中‑该闭锁杠杆(2)具有杠杆臂(22),该杠杆臂从该第一臂(16)向外突出,并且第一弹簧(4)以第一端作用在该杠杆臂上,该第一弹簧将该闭锁杠杆(2)预加载到某个位置,在该位置,该闭锁杠杆与设置在闭锁臂(23)的端部的闭锁尖端(25)接合至该控制凸轮(21)的该齿系统(26)中。此外,突出部(200)设置在该闭锁装置的该壳体(1)上,该突出部成形为使得该第一弹簧(4)独立于该闭锁杠杆(2)的该位置抵靠该突出部,并且相对于施加在该杠杆臂(22)上的该弹簧力被横向预加载。
