Abstract

An apparatus for helping to protect an occupant of a vehicle seat includes an airbag defining an inflatable volume for receiving inflation fluid from an inflator having first and second ends. The airbag has a first sleeve configured to receive the first end of the inflator and a second end configured to receive the second end of the inflator. The first and second sleeves extend from the airbag.

First claim

What is claimed is:

1. An apparatus for helping to protect an occupant of a vehicle seat, comprising:
an airbag defining an inflatable volume for receiving inflation fluid from an inflator having first and second ends, the airbag having a first fabric sleeve configured to receive the first end of the inflator and a second fabric sleeve configured to receive the second end of the inflator, the first and second sleeves extending from the airbag, wherein the first sleeve is formed from a first panel folded over itself and inserted between second and third panels of the airbag defining the inflatable volume: and
stitching extending through the first, second, and third panels.

2. The apparatus recited in claim 1 , wherein the first sleeve comprises multiple layers of fabric material stitched together and extending from the airbag.

3. The apparatus recited in claim 1 , wherein the stitching comprises:
first stitching extending from a first end positioned on the first sleeve to a second end positioned on a periphery of the second and third panels; and
second stitching extending from a first end positioned on the first sleeve to a second end positioned on the periphery of the second and third panels, wherein the first ends of the first and second stitching extend parallel to one another.

4. The apparatus recited in claim 3 , wherein the second ends of the first and second stitching overlap one another on the periphery of the second and third panels.

5. The apparatus recited in claim 3 , wherein the portions of the first and second stitching positioned on the first sleeve extend along a length thereof.

6. The apparatus recited in claim 3 , wherein the portions of the first and second stitching positioned on the first sleeve extend parallel to a fold line over which the first panel is folded over itself to form the first sleeve.

7. An apparatus for helping to protect an occupant of a vehicle seat, comprising:
an airbag defining an inflatable volume for receiving inflation fluid from an inflator having first and second ends, the airbag having a first fabric sleeve configured to receive the first end of the inflator and a second fabric sleeve configured to receive the second end of the inflator, the first and second sleeves extending from the airbag, wherein the first sleeve comprises a base extending from a periphery of the airbag, an opening for receiving the first end of the inflator, and tabs aligned with the opening and positioned on opposite sides of the inflator.

8. The apparatus recited in claim 7 , further comprising a clip for extending around the tabs and the first end of the inflator for securing the same together.

9. The apparatus recited in claim 7 , wherein first stitching extends around the opening.

10. The apparatus recited in claim 9 , wherein second stitching extends around the first stitching and through the tabs.

11. The apparatus recited in claim 1 , wherein the airbag comprises a center side air bag.

12. An apparatus for helping to protect an occupant of a vehicle seat, comprising:
an airbag defining an inflatable volume for receiving inflation fluid from an inflator having first and second ends, the airbag having a first sleeve configured to receive the first end of the inflator and a second sleeve configured to receive the second end of the inflator, the first sleeve being formed from a first panel folded over itself and inserted between second and third panels of the airbag defining the inflatable volume, wherein first stitching extends from a first end positioned on the first sleeve to a second end positioned on a periphery of the second and third panels, wherein second stitching extends from a first end positioned on the first sleeve to a second end positioned on the periphery of the second and third panels, the first ends of the first and second stitching extending parallel to one another.

13. The apparatus recited in claim 12 , wherein the second ends of the first and second stitching overlap one another on the periphery of the second and third panels.

14. The apparatus recited in claim 12 , wherein the portions of the first and second stitching positioned on the first sleeve extend along a length thereof.

15. The apparatus recited in claim 12 , wherein the portions of the first and second stitching positioned on the first sleeve extend parallel to a fold line over which the first panel is folded over itself to form the first sleeve.

16. The apparatus recited in claim 12 , wherein the first sleeve comprises a base extending from a periphery of the airbag, an opening for receiving the first end of the inflator, and tabs aligned with the opening and positioned on opposite sides of the inflator.

17. The apparatus recited in claim 16 , further comprising a clip for extending around the tabs and the first end of the inflator for securing the same together.

18. The apparatus recited in claim 16 , wherein first stitching extends around the opening.

19. The apparatus recited in claim 18 , wherein second stitching extends around the first stitching and through the tabs.

20. The apparatus recited in claim 19 , wherein the airbag comprises a center side air bag.

21. The apparatus recited in claim 1 , wherein each of the first and second sleeves has a stitched connection with the airbag.

22. The apparatus recited in claim 1 , wherein at least one of the first and second sleeves is formed from a panel extending into the inflatable volume of the airbag.
