Abstract
The present invention is related to a novel inflatable floatation device and a method of forming the same. The device is formed of a one piece double woven fabric having first and second layers which are separable from each other to form a chamber capable of accepting and retaining a gas from an inflation device. The first and second layers are formed by using warps and wefts of yarn that interlace with each other in such a manner as to form separate layers of fabric. The two separate layers of fabric are joined at the periphery of the device via an alteration of the warp and weft interlacing sequence which forms an outer margin. The fabric may be coated with an elastomeric or thermoplastic material to ensure the device is air and water tight.
