Abstract: An energy absorbing bumper (10) includes a back plate (11) which is adapted to be attached to a vehicle. An elastomeric module (12) includes an impact face (13) and upper and lower rails (14, 15) extending from the impact face (13). One or more metallic inserts (30) are molded into the rails (14, 15). Each insert (30) includes a plurality of longitudinally extending, laterally spaced bars (31) which intersect a plurality of laterally extending, longitudinally spaced bars (32) to form adjacent rows of openings (33, 34). A fastener (17) extends through at least one of the openings (33, 34) in each insert (30) to attach the rails (14, 15) to the back plate (11). The inserts (30) minimize the possibility of shearing of the module (12) at the area of fasteners (17).
