Abstract:
A structure comprising a plurality of elastomeric sheets wherein:(a) each of said elastomeric sheets is formed with a multitude of uniformly spaced holes each of which have a periphery that is symmetrical about its center; and (b) said sheets are stacked upon each other in layers such that at least one passageway of continuous elastomeric material is formed through said structure from a first exterior surface to a second exterior surface parallel to said first exterior surface for dissipating compressive forces applied normal to said first and second exterior surfaces, wherein each of said passageways are located between two parallel lines that extend through the centers of holes of all of the different layers of elastomeric sheets and wherein said parallel lines form an obtuse angle with said first and said second exterior surfaces.
