Abstract: A bumper system for reducing injury to a pedestrian struck by an automotive vehicle by lessening the likelihood of pedestrian knee joint damage or underbody entrapment while minimizing the point load applied to the lower leg. The bumper assembly includes a bumper beam having a front surface, cushioning material such as energy absorbent high-density foam disposed on the front surface of the bumper beam, and a pedestrian protection leg spoiler secured to the bumper beam and extending downwardly and forwardly therefrom to position the leading edge of the leg spoiler below the cushioning material. The cushioning material absorbs energy of the initial impact with the leg in the vicinity of the knee, and the leg spoiler contacts the leg at a lower position. The leg spoiler has stiffness characteristics such that the impact load applied by the leg to the leading edge causes the leg spoiler to bend rearward in the manner of a cantilever beam.

Abstract: A bumper system for a motor vehicle includes an energy absorber and a bumper beam connected to the energy absorber and for connection to vehicle structure and having a general B shape. The bumper system also includes a member disposed between the bumper beam and a rail of the motor vehicle to absorb energy during an impact with an object by the bumper system.

Abstract: An energy absorbing bumper assembly is provided, including a tube member and a first energy absorbing element positioned within the tube member, including at least one flange portion that absorbs collision energy by deflecting vertically during collision.

Abstract: A bumper system for a motor vehicle includes an energy absorber and a bumper beam interconnecting the energy absorber and vehicle structure and having a general B shape to absorb energy during an impact with an object by the bumper system.

Abstract: A pedestrian protection apparatus for a truck is provided. The apparatus includes a bumper member mounted to a vehicle, a linkage, a stiffener, an extendible cross-member and an actuator. The extendible cross-member is mounted on a stiffener which in turn is mounted at each end at a first linkage and a second linkage respectively. The pedestrian protection apparatus may extend out from under the vehicle at speeds greater than a predetermined speed in order to prevent injury to a pedestrian in a collision. The linkages are disposed between the extendible cross-member and the bumper.
