Abstract
An elbow or knee pad and a method of making the same are disclosed. The pad includes an elasticized sleeve to surround the joint to be protected and a pad assembly fastened to the sleeve. The pad assembly includes a fabric covering over a polyurethane foam backing. A recess is formed in the polyurethane by pressing a hot die into it and a dense, modified polyurethane is cast in the recess. The combination of polyurethane foam and dense, modified polyurethane provides superior shock absorption and protection from impact.
