Three dimensional protective pads
First Claim
1. A three dimensional protective pad being constructed as a laminate structure including a first top layer of a neoprene having a nylon skin adhered thereto, said top layer is stretchable in all directions a second layer of a non-stretch neoprene-ethylene-propylene-terpolymer and a styrene butadiene rubber combination adhered under said first layer, a third layer of a viscoelastic polyurethane foam, adhered there under is a fourth layer bottom layer of a neoprene having a nylon skin adhered thereto which is stretchable in all directions, including a hardened polyethylene plate removably attached to an upper surface of said top layer.

Abstract
The invention is concerned with a three-dimensional protective pad which is constructed from a laminate structure having a first top layer of a neoprene/nylon skin combination which is stretchable in all directions. There is a second layer of a non-stretchable neoprene adhered under the first layer. Then there is a third layer of a polyurethane foam of a viscoelastic nature adhered under the second layer. Finally, there is a fourth layer of a neoprene/nylon skin combination which is stretchable in all directions adhered under the third layer. This laminated material is now structured into a three-dimensional shape. Therefore, prior to laminating all of the layers, the second and the third layers are adhered to each other first and then a sectional cut is made through layers, the cut surfaces are then closed by cross stitching through the second layer into the third layer and the cut edges are now glued together. The wider the cut and the shape of the cut determine the pitch of the form of the structure and more than one cut determine the curvature of the three dimensional structure.

- 7. A three dimensional protective pad being constructed as a laminate structure including a first top layer of a neoprene having a nylon skin adhered thereto, said top layer is stretchable in all directions, a second layer of a non-stretch ethylene-propylene diene monomer and a styrene rubber combination adhered under said first layer, a third layer of a viscoelastic foam, adhered there under is a fourth bottom layer of a neoprene having a nylon skin adhered thereto which is stretchable in all directions, wherein said second layer (of non-stretchable neoprene) is larger in its overall dimension than the underlying urethane layer forming a lip there between and the first layer of the neoprene nylon skin combination is larger in its overall dimension than said second layer to thereby leave excess material and wherein said excess material is glued over said lip and to an edge of said urethane layer.
