Disclosed is a seat belt retractor having: a frame (10); a safety belt reel (12) rotatably arranged in the frame (10) and capable of receiving a safety belt (14); at least one force limiter (16) capable of rotating the seatbelt reel (12) relative to the frame (10) to release the seatbelt (14) while overcoming the braking torque provided by the force limiter (16); and a switchable coupling device (26) having a switching cage (22) and a coupling element (24), the switching cage (22) being displaceable by means of an actuator (28) from an open position, in which the coupling element (24) is held out of engagement with the seat belt reel (12), into a closed position, in which the coupling element (24) engages on the seat belt reel (12). In order to achieve an axially compact design, the seat belt retractor comprises: an adjuster (38) coupled to an actuator (28); and a freewheel (40) coupling the switching cage (22) with the adjuster (38) such that the adjuster (38) is able to displace the switching cage (22) from the open position to the closed position.

    公开了一种安全带卷收器,具有:框架(10);安全带卷轴(12),能够旋转布置在框架(10)中并且能够接纳安全带(14);至少一个限力器(16),能够使安全带卷轴(12)在克服由限力器(16)提供的制动矩时相对于框架(10)旋转以释放安全带(14);以及可切换的联接装置(26),具有切换笼架(22)和联接元件(24),其中切换笼架(22)能够借助于致动器(28)从打开位置被移位至闭合位置,在打开位置中联接元件(24)被保持为与安全带卷轴(12)脱离接合,在闭合位置中联接元件(24)接合在安全带卷轴(12)处。为了实现轴向紧凑的构造形式,安全带卷收器包含:与致动器(28)联接的调节器(38);以及将切换笼架(22)与调节器(38)联接的自由轮(40),使得调节器(38)能够将切换笼架(22)从打开位置移位至闭合位置。
