Abstract
Abstract A structure of fabric layers is arranged so as to eliminate heat shorts therethrough and comprises a plurality of individually grouped layers, each layer consisting of stacked fabrics. Each of the layers of stacked fabrics is stitched together in quiltlike fashion to form a unitary or integral body. The layers are laid one upon another in offset stitch manner, that is, with the stitch lines of each fabric being disposed intermediate the stitch line of the adjacent fabric so as to avoid a common heat transfer avenue through all layers.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
145 words
The method of assembling a plurality of layers of thermally insulative materials so as to prepare a wearable garment therefrom having substantially no heat leaks at the seams thereof comprising: laying out a first stack of laminae so as to form a first layer, tacking together the laminae of said stack so as to unitize said layer, positioning and tacking additional stacks of laminae so as to form additional unitized layers, positioning said layers, one on top of another with the tacking of each layer disposed in offset relation with respect to the taking of adjacent layers, sewing all said layers together with a common stitch, separating at least the uppermost layer and folding it over said common stitch so as to cover the outer exposed surface of the stitch, and covering the inner surface of the stitch with a heat insulating strip of material.
Claim 2
Independent Claim
145 words
The method of assembling a plurality of layers of thermally insulative materials so as to prepare a wearable garment therefrom having substantially no heat leaks at the seams thereof comprising: laying out a first stack of laminae so as to form a first layer, tacking together the laminae of said stack so as to unitize said layer, positioning and tacking additional stacks of laminae so as to form additional unitized layers, positioning said layers, one on top of another with the tacking of each layer disposed in offset relation with respect to the taking of adjacent layers, sewing all said layers together with a common stitch, separating at least the uppermost layer and folding it over said common stitch so as to cover the outer exposed surface of the stitch, and covering the inner surface of the stitch with a heat insulating strip of material.
Claim 3
Dependent Claim
254 words
An article of manufacture for effectively precluding heat shorts therethrough comprising: a plurality of layers of protective material disposed in surface adjacent relation to one another and secured together by first seam means along a common edge portion thereof to form a layered component of the article having first and second face sides, each of said layers comprising a series of fabric laminae connected together by tacking stitches sewn through each layer at points regularly distributed over the surface thereof so that each of said layers becomes a unitary component of the article, adjacent layers of said layered component being selectively positioned whereby the tacking stitches of one layer is laterally offset relative to the tacking stitches of an adjacent layer so as to thereby obstruct the conductive transfer of heat by said tacking stitches through said layereD component, at least one surface layer of said layered component first face side being folded up and over said seam means so as to constitute a layer for a substantially identical layered component and connected thereto by a second seam means thereby concealing said first seam means from said first face side, and elongate strip means having one longitudinal edge secured to the second face side layer of said layered component and the other longitudinal edge secured to the second face side of said folded over layer thereby covering the second face side of said seam means to insulate same from the conductive transfer of heat through said seam between said first and second face side.
Claim 4
Dependent Claim
254 words
An article of manufacture for effectively precluding heat shorts therethrough comprising: a plurality of layers of protective material disposed in surface adjacent relation to one another and secured together by first seam means along a common edge portion thereof to form a layered component of the article having first and second face sides, each of said layers comprising a series of fabric laminae connected together by tacking stitches sewn through each layer at points regularly distributed over the surface thereof so that each of said layers becomes a unitary component of the article, adjacent layers of said layered component being selectively positioned whereby the tacking stitches of one layer is laterally offset relative to the tacking stitches of an adjacent layer so as to thereby obstruct the conductive transfer of heat by said tacking stitches through said layereD component, at least one surface layer of said layered component first face side being folded up and over said seam means so as to constitute a layer for a substantially identical layered component and connected thereto by a second seam means thereby concealing said first seam means from said first face side, and elongate strip means having one longitudinal edge secured to the second face side layer of said layered component and the other longitudinal edge secured to the second face side of said folded over layer thereby covering the second face side of said seam means to insulate same from the conductive transfer of heat through said seam between said first and second face side.
Claim 5
Dependent Claim
14 words
The article of claim 2 wherein said elongate strip has a reflective coating thereon.
