ABSTRACT:
An impact attenuating device such as a truck mounted attenuator includes at least two cartridges, which are secured together by flanges and angled backing elements on adjacent portions of the upper and lower sheets of the cartridges. The forwardmost bay of the impact attenuating device includes stiffening elements on the lower surface and deformable elements which come closely adjacent to the lower surface of the impact attenuating device in order to urge an impacting vehicle with having a low bumper height upwardly, toward the center of the impact attenuating device. The end of the impact attenuating device initially struck by an impacting vehicle is covered by a resilient collapsible element having parallel pleats and recessed corners, such that the collapsible element can absorb low energy impacts without damage to the impact attenuating device.
