The invention relates to a restraint device for an occupant of a motor vehicle, comprising a safety belt (1), which is equipped with a belt tensioner (2), by means of which the tension on the safety belt (1) can be increased. The vehicle seat (3) is equipped with a tubular receptacle (4) as a seat transverse tube, which at the same time accommodates the belt tensioner (2) in the interior thereof. The belt tensioner (2), which is embodied as a linear tensioner, has a coupling element (7) for the safety belt (1), which coupling element can be moved in a tubular receptacle (4) in a translational manner along a movement axis (6), said coupling element being connected to a drive cylinder (9) by means of a stretching device (8). For this purpose, the safety belt (1) is reduced to approximately half of its width by means of the guide element (13) by rolling up the opposite side edges (12), so that the belt tensioner (2) can be placed in a seat transverse tube having a smaller inner diameter without problems.
本发明涉及一种用于机动车的乘员的具有安全带(1)的约束装置,其配备有带张紧器(2),通过该带张紧器可以提高到所述安全带(1)上的拉力。车辆座椅(3)配备有作为座椅横向管的管状容纳部(4),该管状容纳部同时在其内部空间中容纳带张紧器(2)。实施为线性张紧器的带张紧器(2)具有在管状容纳部(4)中可平移地沿着运动轴线(6)运动的用于安全带(1)的联接元件(7),该联接元件借助于拉伸器件(8)与驱动缸(9)连接。为此,安全带(1)借助于引导元件(13)通过卷起相对而置的侧边缘(12)而大约减少到其一半宽度,使得带张紧器(2)可以被无问题地安置在具有较小内径的座椅横向管中。
