Abstract
Abstract An impact receiving cushion which includes an upper or outer soft quick recovery foam element, preferably of polyurethane, superposed on and adherent to a lower or inner harder liquid proof foam element, preferably of closed cell polyethylene. The upper foam element receives the impact, partially encompasses and exerts a drag on the impacting device butyl transmits such part of the impact as it does not absorb to the lower harder and less resilient foam elements. An outer enclosing cover of fabric or the like may be provided to reduce the soiling of the foam elements in use.
