Abstract

One variation may include a roof rail air bag having a bulge portion constructed and arranged to extend medially into the occupant cabin of a vehicle a distance greater than the remaining portion of the roof rail air bag. Another variation may include a roof rail air bag having a bulge portion constructed and arranged to extend into the occupant cabin of a vehicle the bulge portion extending a distance so as to overlap at least a portion of an area to be protected or blocked by an inflated driver'"'"'s side frontal air bag or passenger side frontal air bag. In one variation, the bulge portion may be integrated into the roof rail air bag cushion design. In another variation, the bulge portion may be a separate bulge air bag which may be deployed adjacent the roof rail air bag.

Claims

1. A product comprising:

a roof rail air bag having a first side constructed and arranged for deployment adjacent a vehicle door and having an opposite second side constructed and arranged to be nearest an occupant cabin of a vehicle, the second side being constructed and arranged so that in an inflated condition the roof rail air bag has a bulge portion which, during deployment in a vehicle, extends medially into the occupant cabin of the vehicle a distance greater than the remaining portion of the roof rail air bag.

2. A product as set forth in claim 1 further comprising a vehicle, and wherein the vehicle includes a passenger'"'"'s side roof rail and a driver'"'"'s side roof rail, and wherein the vehicle includes at least one of a driver'"'"'s side frontal air bag or a passenger'"'"'s side frontal air bag, the roof rail air bag being connected to one of the passenger'"'"'s side roof rail or the driver'"'"'s side roof rail, and wherein the bulge portion of the roof rail air bag overlaps a portion of the passenger'"'"'s side frontal air bag or driver'"'"'s side frontal air bag.

3. A product as set forth in claim 1 further comprising a vehicle, and wherein the vehicle includes a passenger'"'"'s side roof rail, wherein the vehicle includes a passenger'"'"'s side frontal air bag, the roof rail air bag being connected to the passenger'"'"'s side roof rail, wherein the bulge portion of the roof rail air bag extends in front of the passenger'"'"'s side frontal air bag.

4. A product as set forth in claim 1 further comprising a vehicle, and wherein the vehicle includes a driver'"'"'s side roof rail, and wherein the vehicle includes a driver'"'"'s side frontal air bag, the roof rail air bag being connected to the driver'"'"'s side roof rail, wherein the bulge portion of the roof rail air bag extends in front of the driver'"'"'s side frontal air bag.

5. A product as set forth in claim 1 further comprising a vehicle, and wherein the vehicle includes a passenger'"'"'s side roof rail, and wherein the vehicle includes a passenger'"'"'s side frontal air bag, the roof rail air bag being connected to the passenger'"'"'s side roof rail, wherein the bulge portion of the roof rail air bag extends behind the passenger'"'"'s side frontal air bag.

6. A product as set forth in claim 1 further comprising a vehicle, and wherein the vehicle includes a driver'"'"'s side roof rail, and wherein the vehicle includes a driver'"'"'s side frontal air bag, the roof rail air bag being connected to the driver'"'"'s side roof rail, wherein the bulge portion of the roof rail air bag extends behind the driver'"'"'s side frontal air bag.

7. A product as set forth in claim 1 further comprising a vehicle, and wherein the vehicle includes a passenger'"'"'s side roof rail, and wherein the vehicle includes a passenger'"'"'s side frontal air bag, the roof rail air bag being connected to the passenger'"'"'s side roof rail, wherein the bulge portion of the roof rail air bag extends behind the passenger'"'"'s side frontal air bag and adjacent an instrumental panel or dashboard of the vehicle.

8. A product as set forth in claim 1 further comprising a vehicle, and wherein the vehicle includes a driver'"'"'s side roof rail, and wherein the vehicle includes a driver'"'"'s side frontal air bag, the roof rail air bag being connected to the driver'"'"'s side roof rail, wherein the bulge portion of the roof rail air bag extends behind the driver'"'"'s side frontal air bag and adjacent an instrumental panel or dashboard of the vehicle.

9. A product comprising a roof rail air bag having a bulge portion constructed and arranged to extend medially into an occupant cabin of a vehicle a distance greater than a remaining portion of the roof rail air bag.

10. The product of claim 9 wherein the bulge portion extends from a first side of the roof rail air bag at least twice the distance of the remaining portion of the roof rail air bag.

11. A product comprising a roof rail air bag having a bulge portion constructed and arranged to extend into an occupant cabin of a vehicle the bulge portion extending a distance so as to overlap at least a portion of an area to be protected or blocked by an inflated driver'"'"'s side frontal air bag or a passenger'"'"'s side frontal air bag.

12. A method comprising providing a roof rail air bag having a bulge portion constructed and arranged to extend medially into an occupant cabin of a vehicle a distance greater than the remaining portion of the roof rail air bag, folding one portion of the bulge portion over at least one other portion of the bulge portion and thereafter rolling the roof rail air bag up.

13. A method as set forth in claim 12 further comprising attaching an air bag inflator to the roof rail air bag.

14. A product comprising:

a bulge air bag constructed and arranged for deployment adjacent a portion of a roof rail air bag nearest an occupant cabin of a vehicle, the bulge air bag being constructed and arranged so that in an inflated condition the bulge air bag extends medially into the occupant cabin of the vehicle a distance greater than the roof rail air bag.

15. A product as set forth in claim 14 further comprising a vehicle, wherein the vehicle includes a passenger'"'"'s side roof rail and a driver'"'"'s side roof rail;

wherein the vehicle includes at least one of a passenger'"'"'s side frontal air bag or a driver'"'"'s side frontal air bag;

wherein the vehicle includes at least one of a passenger'"'"'s side roof rail air bag or a driver'"'"'s side roof rail air bag;

wherein the roof rail air bag and the bulge air bag are connected to at least one of the passenger'"'"'s side roof rail or the driver'"'"'s side roof rail; and

wherein the roof rail air bag is attached to a first inflator and the bulge air bag is attached to a second inflator.

16. A product as set forth in claim 15 wherein the bulge air bag overlaps a portion of the passenger'"'"'s side frontal air bag or the driver'"'"'s side frontal air bag.

17. The product of claim 14 further comprising a vehicle, wherein the vehicle includes a passenger'"'"'s side roof rail and a driver'"'"'s side roof rail;
