Abstract
Abstract A woven fabric having a plurality of layers, there being outer layers and one or more intermediate layers between the outer layers, tying the outer layers together in such a way as to provide pockets extending warpwise in a generally honeycomb relation to prevent the outer layers from spreading beyond a limited distance when inflated, the opposite edges of the fabric being brought together by one outer layer joining another outer layer opposite it and providing a larger chamber which when inflated will provide a bulge at the opposite edges of the fabric extending lengthwise or warpwise of the fabric.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
136 words
A woven fabric comprising a plurality of layers including outer layers with at least one intermediate layer extending substantially coextensively weftwise of the outer layers and between said outer layers and secured alternately to one outer layer and the other outer layer at least one of the securings being by weaving the layers together warpwise thereof, said opposite outer layers being joined at their opposite warpwise extending edges forming a chamber between said outer layers, said intermediate layers being tied to said outer layers at points spaced weftwise thereof with the ties adjacent the edges spaced from the edges a greater distance than the intermediate ties between said intermediate layers and the outer layers whereby a larger unsupported section is formed along the edges to provide a thicker section along the opposite warpwise edges when inflated.
Claim 2
Dependent Claim
136 words
A woven fabric comprising a plurality of layers including outer layers with at least one intermediate layer extending substantially coextensively weftwise of the outer layers and between said outer layers and secured alternately to one outer layer and the other outer layer at least one of the securings being by weaving the layers together warpwise thereof, said opposite outer layers being joined at their opposite warpwise extending edges forming a chamber between said outer layers, said intermediate layers being tied to said outer layers at points spaced weftwise thereof with the ties adjacent the edges spaced from the edges a greater distance than the intermediate ties between said intermediate layers and the outer layers whereby a larger unsupported section is formed along the edges to provide a thicker section along the opposite warpwise edges when inflated.
Claim 3
Dependent Claim
52 words
A woven fabric as in claim 1 wherein there are two intermediate layers extending between the outer layers, said intermediate layers being secured together by weaving and one intermediate layer being secured to one outer layer by weaving and the other intermediate layer being secured to the other outer layer by weaving.
