<p>An energy absorbing bumper assembly including a mounting means defined by metal mounting plates adapted for attachment to a vehicle and an elongated shell made of elastomeric material disposed adjacent or forwardly of the mounting plate. A pair of urethane energy absorbing block pairs are disposed adjacent the center line of the bumper assembly between the front face of the shell and the mounting plate. Each block pair includes first and second members which are spaced vertically apart and define a cavity adjacent and interiorly the front face of the shell. A second pair of energy absorbing urethane block pairs are disposed adjacent the ends of the assembly between the front face of the shell and the mounting plate. The block pairs define the first bumper means for absorbing a first quantity of energy resulting from specified impacts. A second bumper means of elastomeric material for absorbing a different quantity of energy resulting from impacts other than the specified impacts is disposed within the cavity and extends longitudinally along the shell.</p> |
