ABSTRACT:
Impact is attenuated by a hollow resilient elongated one-piece body formed by a substantially flat reinforced rear wall, a top wall and front, side and bottom walls defining a cavity which is filled with water. A plurality of apertures are provided in the top wall, each of which apertures is defined by resilient walls and is closed by at least one resiliently deformable flap member adjacent to and covering the aperture. In response to a strong impact against the front wall of the body, a series of physical steps occur which result in deflection of the flap members from, followed by water from the cavity upwardly through, the apertures. The flap members return to a position adjacent to and covering the apertures after impact.
