Abstract

A modular headliner assembly (10) includes an inflatable vehicle occupant protection device (14) adapted to inflate away from a roof (18) of a vehicle (12) into a position between a side structure (16) of the vehicle and a vehicle occupant. The modular headliner assembly (10) also includes a headliner (36) for covering an interior portion (38) of the roof (18) and at least one support device (40) for supporting the inflatable vehicle occupant protection device (14) and the headliner in the vehicle (12). The support device (40) includes a bracket (42) having a portion (44) connectable to the inflatable vehicle occupant protection device (14), fastener (202) for connecting the headliner (36) to the bracket, and a fastener (222) for connecting the bracket to the vehicle (12).

2. Apparatus as recited in claim 1, further comprising a fill tube having a portion located in said inflatable vehicle occupant protection device, said fill tube directing inflation fluid into said inflatable vehicle occupant protection device to inflate said inflatable vehicle occupant protection device, said portion of said bracket being connectable to said fill tube and said inflatable vehicle occupant protection device.

3. The apparatus recited in claim 2, further comprising an inflation fluid source for providing said inflation fluid for inflating said inflatable vehicle occupant protection device, said fill tube directing said inflation fluid from said inflation fluid source into said inflatable vehicle occupant protection device.

4. Apparatus as recited in claim 2, wherein said portion connectable to said fill tube and said inflatable vehicle occupant protection device comprises a clamp portion of said bracket, said clamp portion extending around portions of said fill tube and said inflatable vehicle occupant protection device and clamping onto said fill tube and said inflatable vehicle occupant protection device.

5. Apparatus as recited in claim 4, wherein said bracket further comprises a flange portion extending from said clamp portion, said flange portion receiving said second fastening means.

6. Apparatus as recited in claim 5, wherein said bracket comprises a single piece of metal material, said clamp portion comprising a portion of said metal material plastically deformed around said fill tube and said inflatable vehicle occupant protection device to clamp onto said fill tube and said inflatable vehicle occupant protection device.

7. Apparatus as recited in claim 6, wherein said portion of said metal material plastically deformed around said fill tube and said inflatable vehicle occupant protection device comprises a portion of said metal material bent around said fill tube and said inflatable vehicle occupant protection device.

8. Apparatus as recited in claim 1, further comprising a housing for enclosing said inflatable vehicle occupant protection device in a stored position, said at least one support device being connectable to said housing.

9. Apparatus as recited in claim 8, wherein said bracket extends through said housing to help connect said at least one support device to said housing.

10. Apparatus as recited in claim 8, further comprising a fill tube having a portion located in said inflatable vehicle occupant protection device, said fill tube directing inflation fluid into said inflatable vehicle occupant protection device to inflate said inflatable vehicle occupant protection device, said portion of said bracket being connectable to said fill tube and said inflatable vehicle occupant protection device, said portion of said fill tube being enclosed in said housing.

11. Apparatus as defined in claim 1, wherein said inflatable vehicle occupant protection device has a generally elongated configuration extending along the side structure of the vehicle near the intersection of the side structure and the vehicle roof, said headliner having a longitudinal edge extending along the side structure of the vehicle near the intersection of the side structure and the vehicle roof, said at least one support device connecting said inflatable vehicle occupant protection device to said headliner along said longitudinal edge.

12. Apparatus as recited in claim 11, wherein said at least one support device comprises a plurality of support devices spaced along said inflatable vehicle occupant protection device, said plurality of support devices connecting said inflatable vehicle occupant protection device to said headliner along said longitudinal edge.

13. Apparatus as recited in claim 1, wherein said second fastening means connects said bracket to the side structure of the vehicle.

14. Apparatus as recited in claim 1, wherein said second fastening means connects said bracket to a pillar of the vehicle.

15. Apparatus as recited in claim 14, wherein said pillar is one of an A pillar, B pillar and C pillar of the vehicle.

16. Apparatus as recited in claim 1, wherein said second fastening means comprises a threaded fastener.

17. Apparatus as recited in claim 1, wherein said first fastening means is a fir tree fastener.

18. The apparatus recited in claim 4, wherein said clamp portion includes overlying portions of said bracket interconnected with each other by a third fastening means, separate from said first and second fastening means.

19. The apparatus recited in claim 9, wherein said portion of said bracket connectable to said inflatable vehicle occupant protection device bracket is enclosed within said housing, said second fastening means extending through a portion of said bracket positioned outside said housing to connect said bracket to the vehicle structure.

20. Apparatus for supporting an inflatable curtain module and a headliner in a vehicle, the inflatable curtain module including an inflatable curtain and a fill tube having a portion located in said inflatable curtain, said apparatus comprising:

a bracket having a first portion deformed around a portion of said inflatable curtain and said fill tube to clamp onto said inflatable curtain and said fill tube;

a second fastener separate from said first fastener extendable through said bracket to connect said bracket to the vehicle.

21. A modular vehicle headliner assembly comprising:

a vehicle headliner;

an inflatable curtain module; and

a bracket for connecting said inflatable curtain module to said headliner, said bracket having a first portion clamped onto said inflatable curtain module to connect said inflatable curtain module to said bracket;

at least one first fastener extendable through said headliner and said bracket to connect said headliner to said bracket; and

at least one second fastener separate from said first fasteners extendable through said bracket to connect said headliner and said inflatable curtain module to the vehicle, said first fasteners being removable to allow removal of said headliner while leaving said inflatable curtain module connected to the vehicle via said bracket.
