Inflatable fabrics comprising basket-woven attachment points between fabric panels
First Claim
1. An inflatable fabric comprising two layers of fabric in first discrete areas and at least one single layer of fabric positioned at a second discrete area, wherein the two layer(s) and the single layer meet at an interface, the single layer being comprised in part of a two-by-two basket weave pattern adjacent the interface.

Abstract
All-woven inflatable fabrics having areas of two layers and attachment points or “seams” where single layers of fabric are formed. Such single fabric layers may be constructed solely through the utilization of basket weave patterns. These specific single fabric layers provide a relatively effective manner of reducing air permeability within the entire fabric article by decreasing the possibility of yarn shifting upon inflation of the inflatable fabric. Alternatively, the presence of at least a second single fabric layer area adjacent to the first and separated by and narrow double fabric layer area can further reduce the possibility of yarn shifting in the first single fabric layer area. Such a fabric may be utilized in numerous and various applications wherein fabric inflation is desired or necessary. In particular, the inventive fabric may be incorporated within an airbag cushion.

7. An inflatable fabric comprising at least one non-rectangular seam, the seam being formed in part by a curved narrow discrete single layer area and a least one adjacent two layer area within the inflatable fabric, wherein the single layer area and the two layer area meet at a single/double layer interface, the single layer area being formed from a basket weave having an even number of yarns.
