First Claim
1. 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.

Abstract
This invention relates to an air bag system for accommodation behind a vehicle covering. The air bag system contains an air bag, which advances in a main inflating direction when the air bag system is triggered, and a gas generator for supplying the air bag with pressure gas during triggering of the air bag system. The gas generator and the air bag are connected by a gas distributing duct which extends at least partially at an angle with respect to the main inflating direction of the air bag. In this case, the gas distributing duct is formed of air bag material. Furthermore, the invention relates to a manufacturing process and a triggering process for such an air bag system as well as to a motor vehicle having such an air bag system, of which at least the air bag is arranged on a sliding roof frame part.

17. Air bag system for an accommodation behind a vehicle covering, the air bag system comprising:
-
an air bag which advances in a main inflating direction when the air bag system is triggered, said air bag being composed of a flexible material formed into an enclosed integral bag with an axially extending distribution channel integrally formed along one edge of the air bag by part of the bag, said integrally formed distribution channel extending across a major portion of the bag in a direction at an angle to the main inflating direction of the bag, and wherein said integrally formed distribution channel is arranged on the air bag to advance during triggering of the air bag system and emerge first from behind the vehicle covering, the interior of the distribution channel being partially defined by and separated from the remaining interior of the bag by a series of spaced connections which define radial openings therebetween with respect to the axially extending distribution channel to enable communication between the interior of the distribution channel and the remaining interior of the bag, and a gas generator for supplying the air bag with pressure gas during triggering of the air bag system coupled to one end of the axially extending distribution channel so that gas flows axially through the distribution channel and passes radially into the remaining interior of the bag. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)

- 31. The combination of an air bag and a gas generator to be mounted behind a vehicle covering, the air bag being an enclosed integral bag with a portion of the enclosed integral bag formed into a loop that extends longitudinally across a major portion of the bag on one edge thereof, the interior of the loop being separated from the interior of the remaining portion of the integral bag by a series of spaced connections, openings defined between successive connections to enable communication between the interior of the loop and the interior of the remaining portion of the integral bag, the remaining portion of the integral bag being in a folded condition, the gas generator being coupled to one end of the loop such that when gas is generated by the gas generator, the gas flows axially through the loop to be distributed across the integral bag while passing radially out of the loop through the openings into the interior of the remaining portion of the integral bag causing the air bag to extend from its folded condition through a vehicle covering with the loop leading the extension and emerging first from behind the vehicle covering.
