ABSTRACT:
A bumper bar is projected by hydraulic actuators, which communicate with a chamber, which is separate from the actuators and contains hydraulic liquid. The chamber and a floating piston are integrated in the bumper bar. This arrangement permits compact cushioning means to perform a large projecting stroke so that a correspondingly large distance for deceleration is available.
