- 14. The airbag device as defined in claim 13 further including a reinforcing structure embedded within said profile strip and corresponding in shape to said profile strip.
- 15. An airbag device for a motor vehicle, said airbag device comprising:
- an airbag including an inflatable gas cushion;
- a gas generator for filling said airbag;
- a gas conduction pipe which extends through at least a portion of said airbag;
- a profile strip for accommodating said airbag in a packed condition; and
- a reinforcing structure embedded within said profile strip and corresponding in shape to said profile strip.
- 16. The airbag device as defined in claim 15 wherein said profile strip has two parallel limbs and a web interconnecting said limbs, said web being adapted to the shape of said gas conduction pipe.
- 17. An airbag device for a motor vehicle, said airbag device comprising:
- an airbag including an inflatable gas cushion;
- a gas generator for filling said airbag;
- a gas conduction pipe which extends through at least a portion of said airbag; and
- a profile strip for accommodating said airbag in a packed condition, said profile strip having beads for supporting said gas conduction pipe in said profile strip;
- said airbag and said gas conduction pipe forming a single unit;
- said beads moving away from each other during insertion of said unit into said profile strip and moving toward each other after insertion of said unit into said profile strip to support said unit in said profile strip.
- 18. The airbag device as defined in claim 17 wherein said profile strip includes two limbs and a web, said web being adapted to the shape of said gas conduction pipe and said beads being located on said limbs.
- 19. An airbag device for a motor vehicle, the motor vehicle having a roof and a side structure, said air bag device comprising:
- an airbag comprising an inflatable gas cushion inflatable from the vehicle roof and into an inflated position along the vehicle side structure;
- a gas generator for filling said airbag; and
- an envelope in which said airbag is located in a packed condition;
- said envelope including a profile strip having a U-shaped cross-section, said profile strip having two planar parallel limbs and a web interconnecting said limbs, said envelope forming a shooting channel through which said airbag inflates downwardly between the vehicle side structure and an occupant of the vehicle, said shooting channel defining an unfolding direction of said airbag.
- 20. An airbag device for a motor vehicle, the motor vehicle having a roof and a side structure, said airbag device comprising:
