具有张紧器驱动器的带卷收器
摘要：
本发明涉及用于座椅带(30)的带卷收器(10)，包括用于卷绕和展开座椅带的带卷轴(20)和张紧驱动器，所述带卷收器包括以下部件：气体发生器(60)、连接到所述带卷轴(20)的驱动装置(40)、和连接所述气体发生器和所述驱动装置的连接装置(50)，其中所述连接装置具有导管(70)和位于所述导管中的多个推力构件(80)，所述构件在所述气体发生器已经被触发之后被加速并且直接地或间接地驱动所述驱动装置以便卷绕所述带。根据本发明，在所述气体发生器(60)和所述推力构件(80a、80b、80c)的至少一个的面向所述气体发生器的侧(80a’)之间，至少一个密封元件(100a、100b、100c)布置在所述导管(70)中，所述密封元件靠在所述导管的内侧上。
摘要（英）：

The invention relates to a belt retractor (10) for a seat belt (30), comprising a belt reel (20) for winding and unwinding the seat belt, and a tightening drive, comprising the following: a gas generator (60), a drive device (40) connected to the belt reel (20), and a connecting device (50), which connects the gas generator and the drive device, wherein the connecting device has a guide tube (70)and a plurality of thrust members (80) located in the guide tube, said members being accelerated after the gas generator has been triggered and directly or indirectly driving the drive device for winding the seat belt. According to the invention, at least one sealing element (100a, 100b, 100c) is disposed in the guide tube (70) between the gas generator (60) and the side (80a') facing the gas generator of at least one of the thrust members (80a, 80b, 80c), said sealing element resting against the inside of the guide tube (70).
