ABSTRACT:
A unique protective knee pad is disclosed which is comprised of one-piece molded resilient polyurethane foam. The pad has a special U-shaped sole with a transverse bar through the middle portion and a transverse bar at the rear. Two cavities are created by the transverse bars which are adapted to entrap air when the wearer is in the operative kneeling position thereby cushioning the delicate parts of the patella and upper shin, by preventing the outwardly extending portion of the knee from coming into contact with the ground.
