Abstract
A bumper system for motor vehicles includes an energy absorption assembly that extends generally perpendicular to the direction of vehicle travel and is connected with the longitudinal supports of the vehicle frame by crush boxes. The energy absorption assembly has first and second generally parallel bumper members, which support one another along first and second contact surfaces. The first bumper member is slideably supported by the second bumper member and is configured such that upon impact, the first bumper member is slidingly displaced along the first and second contact surfaces both horizontally relative to the longitudinal supports of the vehicle frame and vertically relative to the second bumper member.
