Abstract: A lower stiffener is provided for a bumper of a vehicle. The lower stiffener is mounted on a lower portion of a bumper beam or a front end module (FEM) carrier of the vehicle. The lower stiffener includes a pair of core portions formed by extending in a width direction of the vehicle in an elongated loop shape corresponding to a shape of the bumper of the vehicle, and arranged parallel to each other at a regular interval. A pair of molding portions surrounds the core portions, respectively and a connection portion connects and integrates the pair of molding portions with each other.

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.
