Abstract
An air-bag arrangement for use in a motor vehicle comprises a gas generator(9) which generates gas when an accident occurs. An air-bag is provided to be inflated by the gas. The air-bag comprises three super-imposed fabric layers(2,3,4), the outer peripheries of which are conjoined by a seam(5). A central aperture(6) in the lower-most layer receives the gas outlet(8) of the gas generator. A plurality of apertures(12) are formed in the intermediate layer and seams(13) interconnect the intermediate layer(3) and the lower-most(2) adjacent the apertures. The seams(13) partially surround each aperture, but are not present in a region(14) which is radially outwardly positioned relative to the center of the intermediate layer(3). This arrangement causes the bag, on inflation, to inflate laterally outwardly before inflating towards the occupant of the vehicle to be protected by the bag.
