Abstract: A bumper system for motor vehicles includes a cross member, and at least one crush box positioned between the cross member and the vehicle frame. Two coupling levers have opposite ends operably and pivotally connected with a crush box and cross member. The coupling levers are arranged in a mutually parallel relationship and oriented at an angle relative to vehicle travel, such that the cross member is supported by the crush box for displacement from a ready position toward the vehicle frame in both horizontal and vertical directions. An energy absorption element constructed from a foam material was positioned between a cross member and the crush box, and is clamped between the coupling levers to selectively resist inward movement of the cross member from the ready position upon impact to absorb impact energy.

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.
