ABSTRACT:
An energy absorbing bumper (20) for a vehicle includes an elastomeric bumper module (24) having a longitudinally extending impact face (25) and upper and lower walls (26,27) extending laterally therefrom toward a rear support plate (21) which is attachable to the vehicle and which engages the upper and lower walls (26,27) of the module (24). A plurality of longitudinally spaced upper ribs (31) extend from the impact face (25) and generally laterally along the upper wall (26) toward the rear support plate (21). A plurality of similarly longitudinally spaced lower ribs (32) extend from the impact face (25) and generally laterally along the lower wall (27) toward the rear support plate (21). A longitudinal rail (34) extends from between the upper and lower ribs (31,32) on the impact face (25) toward the rear support plate (21). Upon impact against the impact face (25), the module (24) thereby absorbs the energy of the impact.
