Air bag device
First Claim
1. An air bag device in which a folded air bag having a sewn portion along its outer periphery and an inflator are supported on a retainer, and which is adapted to make the air bag expanded and deployed into a vehicle compartment by a gas generated by the inflator upon collision of a vehicle,wherein the air bag comprises a plurality of base fabrics which are sewn together at outer peripheries thereof, wherein a base of the air bag fixed to the retainer and the outer periphery of the air bag are connected to each other by a connecting member in the process of folding the air bag, and when the air bag is expanded, it breaks the connecting member, said connecting member extending diametrically inwards from the outer periphery of the air bag so as to be sandwiched between the base fabrics, and further including a fixing ring which fixes the base of the air bag, the retainer and the inflator together, said fixing ring being disposed between said base fabrics, and said connecting member being connected to said fixing ring as disposed between said base fabrics.

Abstract
An air bag is formed by sewing a first basic fabric opposed to an occupant and a second basic fabric on the opposite side, at a sewn portion along an outer peripheries of the fabrics. The air bag is folded in a longitudinally longer shape, and an oblong restricting member is wound around a central portion of the air bag to fix the air bag in a bundling manner, and then the air bag is vertically folded. In the process of expansion of the air bag, the air bag bundled by the restricting member is first expanded vertically and then expanded laterally after breakage of a breaking portion of the restricting member which cannot withstand a tension. Thus, by providing the restricting member, the shape and direction of the air bag can be controlled as desired in the process of deployment.
