Abstract: The invention relates to a life-saving garment whose material comprises a buoyant heat insulator (1), preferably an air bladder sheet, as well as to a method of manufacturing said garment. Manufacturing of life-saving garments involves a plurality of working steps, thus increasing the price of a garment. An object of the invention is to provide a simple and effective life-saving garment whose manufacturing costs are low.The garment substantially comprises two essentially continuous, human-shaped material sheets, affixed to each other only by means of an edge joint (2). One side of the garment is provided with a watertight zipper (3) as well as with a face opening (4), adapted to prevent water from flowing in the opening. The garment preferably consists of two suits placed one inside the other, the top suit being turned inside out, said joints (2) of the suits being confined in an air space (5) between the suits.

Abstract: A method of making a seam in laminated textile fabric. The edges of a pair of sheets of fabric are separately stitched with reinforcing stitching and the stitched edges are then positioned in lapping relation. A layer of a thermoadhesive is interposed between the lapping edges and on the application of heat and pressure to the lapping edges the thermoadhesive layer will melt and permeate the fabric, as well as the stitching, to provide a tight and waterproof seam.
