ABSTRACT:
An energy absorbing device adapted to be connected between a motor vehicle bumper and a motor vehicle frame includes a liquid filled cylinder having a piston therein connected to the impact receiving device. The cylinder is provided with a plurality of weakened areas along the length of the cylinder which will rupture in sequence upon application of force by the piston to the liquid, thereby dissipating the force applied to the impact receiving means. A spring or an explosive device may be provided between the piston and closed end of the cylinder or the interior walls of the cylinder may be roughened to provide additional resistance to the movement of the piston within the cylinder. Additionally, the liquid expelled from the cylinder can be channeled through various devices to apply a reverse force to the impact receiving device.
