ABSTRACT:
An inflatable vehicle occupant restraint confinement having separate inner and outer inflatable chambers formed from a single sheet of material. Fluid port means communicating with both the inner and outer chambers is provided in the form of a cylindrical diffuser. The method of making the confinement includes folding a flat pattern of a single layer of material about its midline and seaming the margins except for a portion adapted for receiving the port means. The folded wall of the confinement thus formed is then folded inwardly to form a pocket and define new folded margins of the pocket which are then seamed together to form the pocket into an inner chamber and an outer chamber formed by the remainder of the material surrounding the inner chamber.
