Abstract
An athletic protective pad comprising a foam body composed of a layer of open cell foam and a first and second layer of closed cell foam and having a foam chest portion, a foam shoulder member and a hinge attaching the chest portion to the shoulder member, with the chest portion and shoulder member each presenting a periphery. The hinge member includes tape attached to an outer surface of the foam body across a portion of the peripheries of the chest portion and shoulder member to allow the shoulder member to rotate in a first direction relative to the chest portion and preventing rotation thereof in a second direction. The first and second layers of closed cell foam are secured to opposing surfaces of the open cell foam layer, with the layers presenting a sandwich configuration. The layer of open cell foam has a first thickness and the layers of closed cell foam each have a second thickness, where the first thickness of the open cell foam is approximately 1.8 times the second thicknesses of the closed cell foam to maximize the trapped air content within the layer of open cell foam and thus, improve the pad's impact resistance.
