Abstract

An air-bag housing comprising a rectangular frame (1) defining an opening and having a mounting arrangement in the form of flanges (7) to mount the frame in position within a motor vehicle. The frame supports a housing-forming element (21) formed, for example, of fabric. This forms a housing having walls (71, 72) and a floor. The walls (71, 72) are formed seamlessly by folding the fabric in half about a fold-line, and tucking one end of the fold-line into the other end of the fold-line, and inserting the frame between the pieces of fabric to lie adjacent the fold-line. The floor is formed by a plurality of floor-forming tabs (25, 26, 35, 36 etc) carried by the fabric forming the side-walls of the housing. The tabs are folded inwardly to at least partly overlie each other and are secured in position to form the floor of the housing by studs (15, 16, 17, 18) provided on the inflator which pass through co-aligned apertures (27, 30, 38, 39) in the floor-forming tabs (25, 26, 35, 36 etc).
