Abstract
A bumper includes a beam and an energy absorber supported on its face. The beam includes front and rear beam walls, with a pair of apertures in the front beam wall, and further the energy absorber includes a pair of tubular structural columns extending from its front wall through the aperture in the front beam wall to the rear beam wall. By this arrangement, the front wall of the energy absorber receives support from the rear beam wall via the structural columns during a vehicle crash.
