Abstract: PROBLEM TO BE SOLVED: To effectively prevent the increase of the inner pressure of an air bag in the case of abutting of a crewman by, in the manufacture of the air bag composed of a film-shaped bag body having elongation more than 100% at the time of fracture, blow-forming a thermoplastic or thermosetting elastomer to form the film-shaped bag body having a required shape. SOLUTION: In order to effectively ease the increase of the inner pressure of an air bag, the air bag is composed of a film-shaped bag body having elongation more than 100% at the time of fracture. As a method for manufacturing the air bag using an elastomer, a blow-forming method for forming a seamless film-shaped bag body on one stage is applied. In the blow-forming method, at least one kind of thermoplastic elastomer or thermosetting elastomer is formed into the film-shaped bag body having a required air bag shape whose thickness is 10-700μm preferably 100-500μm by a blow-forming process.

Abstract: PURPOSE:To accomplish a shape maintaining function of an air bag and thermal protection of an opening part for an inflator by means of a single sheet of glass fiber fabric by connecting the glass fiber fabric serving as heat resistant fabric and reinforcing fabric to at least the circumference of the opening part for the inflator in an air bag main body fabric. CONSTITUTION:Glass fiber fabric 7 serving as heat resistant fabric and reinforcing fabric is connected to at least the circumference of an opening part 13 for an inflator in an air bag main body fabric 4 by stitching with stitching thread 10. The air bag main body fabric 4 and the glass fiber fabric 7 are integrally fixed in a base plate 3 with an inflator l via a retainer 2 auxiliarily arranged above the air bag main body fabric 4 and the glass fiber fabric 7 by means of a mounting machine screw 11. In this way, a shape maintaining function of an air bag in the operation of the air bag and protection of the opening part for the inflator from high temperature gas generated from the inflator l can be accomplished by means of a single sheet of the glass fiber fabric 7. Therefore, a lightweight, inexpensive, and compact air bag can be provided.

Abstract: PROBLEM TO BE SOLVED: To provide a folding method and the arrangement of vent holes, which ensures reliable expansion in the air bag formed out of a thermoplastic film such as urethane excellent in stretchability and the like. SOLUTION: It is so constituted that this air bag is formed out of a thermoplastic film such as urethane excellent in stretchability and the like, and is provided with an opening 5 for an inflator bored roughly at the center, and with a plurality of vent holes 7 and 7 bored appropriately around the aforesaid opening. In this case, the air bag is folded in two steps, namely, the first half step where it is folded in at the first half folding lines L1 and L2 in the prescribed direction, and continuously the latter half step where it is folded in at the latter half folding lines L3 and L4 perpendicularly intersected with the first half folding lines L1 and L2 respectively. And the air bag is folded in so that a plurality of vent holes 7 and 7 are positioned at places adjacent to the latter half folding lines L3 and L4.
