ABSTRACT:
An energy absorber adapted to be interposed between relatively movable rigid support and impact receiving elements and including a sheet metal plate of rectangular shape. The plate is provided with two asymmetric spaced U-shaped slots and a pair of spaced parallel slots to divide the plate into a continuous integral outer portion; an asymmetric pair of generally U-shape inner portions, the legs of which are integrally connected to the continuous outer portion by bridging portions; and a center portion of rectangular shape integrally connecting the bights of the inner portions. The outer portion is secured to one of the elements and the center portion is secured to the other by a rigid post. Upon impact loads applied to the impact receiving element, the U-shape inner portions fold relative to each other and the outer portion about the bridging portions and the center portion folds upon itself and relative to the U-shape inner portions to form the energy absorber into generally trapezoidal shape and absorb energy.
