Abstract:
Air bag system for an accommodation behind a vehicle covering, the air bag system comprising:(1) an air bag, which advances in a main inflating direction when the air bag system is triggered, a. the air bag being comprised of coextensively overlapped material in sealing relation defining a main body of the air bag, b. a gas distributing duct extending along one edge of the air bag having an inlet at one end and defining an axial flow passage, at least partially at an angle with respect to the main inflating direction, said gas distributing duct being integrally constructed as part of the air bag and integrally interconnected with the main body of the air bag, and wherein the gas distributing duct is arranged on the air bag to advance during triggering of the air bag system and emerge first from behind the vehicle covering, c. a plurality of reinforcing interconnections of the overlapped material transversely spaced apart, relative to the main inflating direction, between the gas distributing duct and the main body of the air bag to define therebetween radial flow passages from the gas distributing duct into the main body of the air bag for enabling inflating gas flowing axially through said gas distributing duct to flow radially out of the gas distributing duct and into the main body of the air bag, and (2) a gas generator for supplying the air bag with pressure gas during triggering of the air bag system that is coupled to the inlet of the gas distributing duct.
