The invention relates to a belt retractor for a seat belt of a motor vehicle, comprising: a belt shaft (2) which is rotatably mounted in a housing frame (1); a profile head (3) which can be locked relative to the housing frame (1); the invention relates to a safety belt retractor (1) comprising a profile head (3) for locking a safety belt shaft (2), a multi-stage first force-limiting device (4), the first force-limiting device (4) being coupled to the profile head (3) and to the safety belt shaft (2), the first force-limiting device (4) allowing a force-limiting relative rotation of the safety belt shaft (2) with respect to the locked profile head (3), and at least one second force-limiting device (5), the force-limiting device (5) being coupled to the profile head (3) and to the safety belt shaft (2). In an initial state, the second force-limiting device (5) is decoupled such that a relative rotation of the belt shaft (2) with respect to the locked profile head (3) takes place without the engagement of the force-limiting of the second force-limiting device (5).

    本发明涉及一种用于机动车辆的座椅安全带的安全带卷收器,该安全带卷收器包括:安全带轴(2),该安全带轴可旋转地安装在壳体框架(1)中;型材头(3),该型材头能够相对于该壳体框架(1)被锁定;多级第一力限制装置(4),其中该第一力限制装置(4)联接到该型材头(3)并且联接到该安全带轴(2),其中该第一力限制装置(4)允许该安全带轴(2)相对于被锁定的该型材头(3)进行受力限制的相对旋转,并且该安全带卷收器包括至少一个第二力限制装置(5),其中,在初始状态下,该第二力限制装置(5)解除联接,使得该安全带轴(2)相对于被锁定的该型材头(3)的该受力限制的相对旋转在不具有该第二力限制装置(5)的受力限制的参与的情况下发生。
