The invention relates to a tightening device for a safety belt component, comprising a gas generator for generating a compressed gas; a piston drivable by the compressed gas; a pull cord (4) connected to the piston, the pull cord being connectable to a safety belt component displaced during a tightening movement; a tightener tube (5) for receiving and guiding the piston, and a guide block (1) forming a cord guide, in which guide block a receptacle (2) for receiving the gas generator and a pressure chamber (3) fluidically connected to the receptacle (2) are designed, the guide block (1) being connected to the tightener tube (5), the guide block (1) has a pressure chamber (3), and the pull cord (4) extends linearly from the tightener tube (5) through the pressure chamber (3) in the direction of piston movement (6), characterized in that the guide block (1) forms a linear guide (7) which adjoins the pressure chamber (3) and which is designed such that the linear guide (7) extends in the direction of piston movement (6) in the direction of piston movement (6) in the direction of piston movement (6) in the direction of piston movement (6). The guide block (1) is designed such that the pull cord (4) can be led out of the guide block (1) parallel to the direction of movement (6) of the piston on the side opposite the tightener tube (5).

    本发明涉及一种用于安全带部件的收紧装置,所述收紧装置具有用于产生压缩气体的气体发生器;可由所述压缩气体驱动的活塞;连接至所述活塞的拉绳(4),所述拉绳可与在收紧运动中发生位移的安全带部件连接;用于容纳和引导所述活塞的收紧器管(5)和形成绳引导部的导向块(1),在所述导向块中设计有容纳所述气体发生器的容纳部(2)和与所述容纳部(2)流体技术连接的压力室(3),其中所述导向块(1)与所述收紧器管(5)连接,并且所述拉绳(4)在活塞运动方向(6)上从所述收紧器管(5)穿过所述压力室(3)直线延伸,其特征在于,所述导向块(1)形成与所述压力室(3)相接的线性引导部(7),所述线性引导部被如此构造,使得所述拉绳(4)可平行于所述活塞运动方向(6)在与所述收紧器管(5)相对而置的侧面上从所述导向块(1)引出。
