ABSTRACT:
A vehicular impact absorbing apparatus includes a pair of tubular guide rails having a guide slit longitudinally formed at the upper part of each guide rail fixed to the ground. Sliders are movably mounted in the guide rail at predetermined intervals, the upper part of each slider is laid on the upper part of the guide rail through the guide slit. Cushion units are mounted on the upper part of each slider. Each cushion unit is elastically deformed by vehicular impact while retracting along the guide rail. Cushion pins are mounted across the guide rails at predetermined intervals between the sliders that also absorb the kinetic energy of an impact by being broken by the rearward retracting slider. A stopper is installed around the rear end of the guide rail for stopping the retracting cushion units. A successive cushion and deceleration of the impact is possible in this arrangement.
