  • Kinetic energy absorbing pad
    Patent number: 4227593
    Abstract: A pad adapted to sustain an impact load by stepwise absorption of kinetic energy. The pad incorporates a collapsible, i.e., crushable core adapted to undergo stepwise deformation under the force of the impact load. Stepwise deformation of the core provides, during impact load application, a significant lowering of the peak dynamic load sustained by the pad and applied to the pad support. The normally encountered high buckle-initiating peak loads are entirely avoided by the present pad.
