ABSTRACT:
An impact absorbing device comprising a hollow polyhedral body formed with a plurality of elongated cutouts in each of its side walls. These cutouts extend in parallel relation in a direction substantially orthogonal with respect to the longitudinal axis of the polyhedral body, and each cutout has one of its longer edges protruding outward and the other longer edge protruding inward. The polyhedral body is subjected to deformation or partial breakage to absorb an impact imparted to a vehicle as when the vehicle collides against another. The device may be combined with a conventional shock absorber to enhance the effect of impact absorption.
