摘要： PROBLEM TO BE SOLVED: To provide an elastomer air bag constituted sufficiently resistant to tensile stress at inflation. SOLUTION: A front panel 12 and a rear panel 14 both made of an elastomer are joined together to compose an air bag 10. Regarding the rear panel 14, the direction showing large tensile strength is identified as up and down direction. On introducing the gas from an infrator to the folded body of the air bag 10, the film adhered portion probably suffering large tensile stress will show superior resistance to the stress. Moreover, the air bag cannot enlarge its own bulk compred with the ones using thick panel films.

摘要： PROBLEM TO BE SOLVED: To provide an elastomer air bag having a structure with superior resistance to an impulsive tensile stress during its inflation. SOLUTION: A front panel 12 and a rear panel 14 both made of an elastomer are joined together to compose an air bag 10. In the central portion of the rear panel 14, a reinforcement film 20 is adhered to the rearpanel 14 so that the film elongates over the whole length of the rear panel 14. On introducing the gas from an inflator to the folded body of the air bag 10, the film adhered portion probably affected with large local tensile stress will show superior resistance to the stress.

摘要： PROBLEM TO BE SOLVED: To provide a resin air bag formed into a predetermined folded shape. SOLUTION: An air bag 1 is formed into a bag shape by overlapping a resin sheet (front panel) 2 constituting the front face and a resin sheet (rear panel) 3 constituting the rear face together and connecting their circumference parts together. The folded air bag 1 is stored in a fabric bag or a case with a lid or wrapped by a wrapping cloth so as to be kept in the folded shape. Then, the folded air bag 1 is inserted into a heat processing device so as to be heated to the temperature lower than a softening point of the resin sheets 2, 3 by 10-20 deg.C, and kept at that temperature for 1-10 minutes desirably, and then, cooled down. In this way, the air bag 1 is formed into a folded shape, so that it is kept folded when it is pulled out from the bag/case or unwrapped from the wrapping cloth.

摘要： PROBLEM TO BE SOLVED: To orient a connection part between synthetic resin sheets constituting an air bag to the inner panel direction when the air bag is inflated. SOLUTION: An air bag 1 is formed by connecting a resin sheet round front panel 2 to a resin sheet round rear panel 3 provided with an inflator insertion opening 4 in the center. The thickness of the front panel 2 is thicker than that of the rear panel 3, so that a connection part 5 is oriented to the inner panel direction when the air bag 1 is inflated.

摘要： PROBLEM TO BE SOLVED: To connect synthetic resin sheets constituting an air bag together very firmly. SOLUTION: In an air bag 1, a round front panel 2 made of a synthetic resin sheet, a round rear panel 3 which is made of a synthetic resin sheet and is provided with an inflator insertion opening 4 in the center, are connected together by means of a connecting resin 5. The circumferential edge part of the front panel 2 is protruded outward from the circumferential edge part of the rear panel 3. In the front panel 2, the connecting resin 5 is connected to the end face and to the inside face. In the rear panel 3, the connecting resin 5 is connected to the end face and to the outside face. In the corner angle part in which the outer circumferential face of the connecting resin 5 and the rear panel 3 side face cross each other, a recessed stepped part is extended along the outer circumferential face.

摘要： PROBLEM TO BE SOLVED: To provide an elastomer air bag having a structure preventive of local inflation. SOLUTION: A reinforcement film 20 is adhered where strong gas pressure will act locally. On introducing the gas from an inflator to the folded body of the air bag 10, the film adhered portion probably affected with larde pressure will not then inflate locally.

摘要： PROBLEM TO BE SOLVED: To obtain air bags that are safe to human bodies and have stabilized performances in no need of organic solvent by forming a coating layer of a specific silicone-modified thermoplastic polyurethane resin on the surface of a woven fabric. SOLUTION: The base cloth for air bags is prepared by forming a coating layer that is a silicone-modified thermoplastic polyurethane resin containing 5-40 wt.% of a siloxane component prepared by reaction between a polyol, for example, poly(ethylene adipate), a polyisocyanate, for example, 4,4'- diphenylmethane diisocyanate, and an active hydrogen-bearing polysiloxane represented by the formula (R1a-R1f are each a 1-8C alkyl or an aryl; R2a-R2f are each an alkylene or a divalent substituent bearing an ester linkage or an ether linkage; (n) is 5-20), and when necessary, a chain extender, in a thickness of 10-100 μm on the surface of a woven fabric.
