Abstract
Abstract A bumper assembly for a vehicle includes an elongated impact bar mounted on the vehicle having inner and outer surfaces. A rib, integrally formed at a central portion of the impact bar, projects outwardly from the outer surface and extends a substantial portion of the length of the impact bar. A reinforcing member is mounted on the outer surface of the impact bar and covers a substantial portion of the length of the rib. An energy-absorbing medium is mounted on the outer surface of the impact bar and covers a substantial portion of the lengths of the reinforcing member and the ribs. A fascia is attached to the vehicle and covers the energy-absorbing medium.
