ABSTRACT:
A resilient or shock-absorbing bumper for vehicle, which bumper is characterized by its simple, low cost and compact construction, and by being free of movable mechanical parts, and, consequently, which does not need any maintenance to preserve its operativeness. This resilient vehicle bumper includes an elongated rigid channel member of U-shape transverse cross-section defining an open side and an opposite side securable to a vehicle, an elongated rubber membrane mounted in the channel member, projecting from the open side thereof, and having transverse internal partitions dividing the membrane into a series of closed cells serially arranged along the channel member, and sand filling alternate cells, while the other cells are empty to allow lateral bulging of the sand-filled cells in the empty cells upon impact against the rubber membrane. Reinforcing bars are embedded longitudinally in the front portion of the rubber membrane.
