Abstract:
A system for impact absorption for an automotive vehicle having a chassis, a front end, a front bumper, and a rear end, said system comprising:at least one front impact receiving member having a front end and a rear end, said receiving member being secured to the vehicle's chassis at said front end of the vehicle proximate said front bumper; a rear absorption device having a front and a rear end, said device being secured to the chassis proximate the rear end of the vehicle; a cable fastened between said receiving member and said rear end of said absorption device; a pulley having a rotational axis and having said cable arrayed over said pulley, the pulley being interposed between the receiving member and said rear absorption device; and a deformable pulley support having one end connected to the pulley and another end connected to the vehicle chassis, said support adapted to translate said rotational axis of said pulley from a first position to a second position in response to, and in the direction of a colliding force directed perpendicular to the front end of the vehicle, said colliding force forcing the receiving member toward the rear end of the vehicle thereby causing a tensioning force on the cable that collapses said deformable pulley support in the direction of the colliding force and causes the absorption device to collapse in a direction opposite the direction of the colliding force.
