Abstract

An air bag module comprises an air bag inflator and an air bag inflatable by the air bag inflator. The air bag has a hole to receive the air bag inflator and at least one tab attached to the air bag near the hole to assist in the insertion of the air bag inflator into air bag. The air bag has a heat shield near the air bag inflator.

Claims

1. An air bag module, comprising:

an air bag inflator;

an air bag inflatable by said air bag inflator, said air bag having a first hole and a second hole therethrough, each of said holes sized to receive at least a portion of said air bag inflator; and

a first tab located proximate said first hole and a second tab located proximate said second hole, said first tab foldable over at least a portion of said first hole and second tab foldable over at least a portion of said second hole, said first tab having a third hole and said second tab having a fourth hole wherein said third hole is sized to match said first hole and said fourth hole is sized to match said second hole.

2. The air bag module of claim 1 wherein said air bag inflator comprises a first end and a second end, said first end secured within said first hole and said third hole and said second end secured within said second hole and said fourth hole.

3. The air bag module of claim 1 including a housing wherein said housing has at least one opening to receive at least one tab.

4. An air bag module, comprising:

an air bag inflator;

an air bag inflatable by said air bag inflator, having at least one hole to receive said air bag inflator;

a least one tab attached to said air bag proximate said at least one hole; and

a heat shield located within said air bag, wherein said heat shield comprises fabric sewn to said air bag.

5. The air bag module of claim 4 wherein said air bag has a seam, said heat shield covering said seam.

6. An air bag module, comprising:

an air bag inflator;

an air bag inflatable by said air bag inflator, having a first hole and a second hole, each of said holes sized to receive at least a portion of said air bag inflator;

at least one flap operatively attached to said air bag, said at least one flap securing said air bag inflator to said air bag; and

a housing for protecting said air bag, said housing having at least one slot to receive said at least one flap.

7. The air bag module of claim 6 wherein said at least one flap comprises a first flap located proximate said first hole and a second flap located proximate said second hole, said first flap having a third hole and said second flap having a fourth hole wherein said third hole is sized to match said first hole and said fourth hole is sized to match said second hole.

8. The air bag module of claim 7 wherein said air bag inflator comprises a first end and a second end, said first end secured within said first hole and said third hole and said second end secured within said second hole and said fourth hole.

9. The air bag module of claim 6 including a heat shield within said air bag.

10. The air bag module of claim 9 wherein said heat shield comprises fabric sewn to said air bag.

11. The air bag module of claim 9 wherein said air bag has a seam, said heat shield covering said seam.
