Abstract
A bumper system includes a tubular beam having front and rear walls, and a plurality of horizontally-extending walls that interconnect the front and rear walls. An energy absorber has a rear surface with a recess shaped to mateably receive and support the beam, and includes end sections that extend to be coplanar with the rear wall of the beam. The end sections cover the front wall and also at least partially cover a top, bottom and ends of the beam, and are constructed to flex and absorb energy to reduce a likelihood of vehicle damage. In one form, the end sections include honeycomb sections that engage beam mounts to transfer impact energy directly to the mounts. In another form, the end sections include cantilevered flanges that extend outwardly from ends of the energy absorber for impact absorption at the vehicle corners.
