The invention relates to a belt tensioner (1) for a safety belt system, comprising a motor (2), an inertial mass (3), a transmission (4), a movable belt fastening point (5) and a switchable clutch (6). The motor (2) enables rotational movement of the inertial mass (3). A switchable clutch (6) is arranged between the motor (2) and the belt fastening point (5) such that, in a first switching state, the inertial mass body (3) and the belt fastening point (5) are kinematically decoupled from one another, and, in a second switching state, the transmission (4) kinematically couples the inertial mass body (3) to the belt fastening point (5), in this way, a rotational movement of the inertial mass body (3) is converted into a predetermined movement of the belt fastening point (5).
公开了一种用于安全带系统的带拉紧器(1),该带拉紧器具有马达(2)、惯性质量体(3)、传动装置(4)、可运动的带紧固点(5)和可切换的离合器(6)。马达(2)能够使惯性质量体(3)旋转运动。可切换的离合器(6)布置在马达(2)与带紧固点(5)之间,使得在第一切换状态下,惯性质量体(3)和带紧固点(5)在运动学上彼此脱联,并且在第二切换状态下,传动装置(4)将惯性质量体(3)与带紧固点(5)在运动学上联接,从而使得惯性质量体(3)的旋转运动被转化为带紧固点(5)的预定运动。
