Abstract An energy absorbing bumper assembly including a shell member or valance having apertures therein and yieldable bumper members for absorbing impact energy located within those apertures. The shell member or valance has spring-like members disposed on the rearward surface thereof such that it will deflect upon impact and thus allow the yieldable bumper members to absorb impact energy. The assembly may be provided with a two-tone appearance, the shell member being one color, such as the color of the automobile to which the assembly is secured, and the bumper members being another color such as black.
