1. An inflatable module comprising:
- at least two breathable fabric layers being sealed together by a seal to form an inflatable cavity, each breathable fabric layer comprising an air impermeable, moisture vapor permeable layer and an adjoining inner reinforcing textile layer, an adhesive, wherein the inner reinforcing textile layers are encapsulated by the adhesive and the air impermeable, moisture vapor permeable layers are in contact with the adhesive, to form the seal between the at least two breathable fabric layers, and a means for inflating said inflatable cavity incorporated into said module.

Abstract
The present invention is an inflatable module which is breathable, i.e. permits the passage of moisture vapor, and which further incorporates a pressure relief means for reducing pressure in the inflated portion should the module be subjected to sudden or excessive stress. In a preferred embodiment of the invention, a pressure relief valve is incorporated as the pressure relief mechanism in the inflatable module. The present invention is further directed to an inflatable module having increased seal strength to make it capable of withstanding the rigors of use.
