    • A force limiter in a vehicle occupant restraint system comprises a tube, a piston displaceably arranged in the tube, a traction and thrust devices connected with the piston element, and at least one roller body. The piston has a stop provided thereon and a radial exterior with at least one ramp surface. The roller body on displacement of the piston in a direction of movement travels along the ramp surface up to the stop and is pressed radially outwards into a wall and plastically deforms the wall. The stop has an extension which protrudes in the direction of movement and extends radially outside a point of the roller body which lies furthest opposed to the direction of movement.
    • 车辆乘员约束系统中的限制器包括管,可移动地布置在管中的活塞,与活塞元件连接的牵引和推力装置以及至少一个辊体。 活塞具有设置在其上的止挡件和具有至少一个坡道表面的径向外部。 活塞沿运动方向移动的辊体沿斜面行进直到止动件,并被径向向外压入壁中并使壁发生塑性变形。 止动件具有在运动方向上突出的延伸部,并且径向地位于与主体的移动方向最相对的位置。
