Abstract

An airbag handling device is disclosed. The handling device may be located adjacent mounting locations of an inflatable curtain airbag. The handling device may be a stiffening member that has a stiffness greater than that of the inflatable curtain. The handling device may also be an inflatable chamber that is inflated separately from the cushioning chamber of the inflatable curtain. The handling device may help prevent twisting of the inflatable curtain between mounting locations and aid in positioning the inflatable curtain during handling or installation into a vehicle.

Claims

1. An airbag handling device, comprising:

a handling member positionable adjacent mounting locations on an inflatable curtain, the handling member having a stiffness greater than the inflatable curtain, such that the handling member is configured to aid in positioning the inflatable curtain during installation within a vehicle.

2. The handling device of claim 1, wherein the handling member is collapsible.

3. The handling device of claim 1, wherein the mounting locations are attachment tabs and the handling member is configured to engage the attachment tabs of the inflatable curtain.

4. The handling device of claim 3, wherein the handling member prevents twisting of the inflatable curtain between attachment tabs during installation of the inflatable curtain within the vehicle.

5. The handling device of claim 3, wherein the handling member is slidably engageable with the attachment tabs of the inflatable curtain.

6. The handling device of claim 1, wherein the handling member is configured to be located outside of the inflatable curtain.

7. The handling device of claim 1, wherein the handling member is removably attachable to the inflatable curtain, such that the handling member is removable after the inflatable curtain is installed in a vehicle.

8. The handling device of claim 7, further comprising a releasable fastener for attaching the handling member to the inflatable curtain.

9. The handling device of claim 1, wherein the handling member is permanently affixable to the inflatable curtain, such that the handling member remains affixed to the inflatable curtain after the inflatable curtain is installed in the vehicle.

10. The handling device of claim 2, wherein the handling member comprises an elongated member having a length sufficient to span a plurality of mounting locations on the inflatable curtain.

11. The handling device of claim 10, wherein the elongated member is comprised of multiple portions arrangeable in a non-linear orientation with respect to each other.

12. The handling device of claim 10, wherein the elongated member has telescoping portions such that the length of the elongated member is variable.

13. An airbag assembly, comprising:

an inflatable cushion having mounting locations disposed thereon, the mounting locations configured to be mounted to a vehicle; and

a twist prevention device that extends adjacent a plurality of the mounting locations to prevent twisting of the inflatable cushion between mounting locations during installation of the inflatable cushion within the vehicle.

14. The airbag assembly of claim 13, wherein the inflatable cushion is an inflatable curtain configured to provide impact protection along a side of the vehicle.

15. The airbag assembly of claim 14, wherein the twist prevention device is contoured to an upper edge of the inflatable curtain.

16. The airbag assembly of claim 14, wherein the twist prevention device is an inflatable twist prevention device.

17. The airbag assembly of claim 16, wherein the twist prevention device is an inflatable chamber, inflatable separate from a cushioning chamber of the inflatable curtain, the inflatable chamber configured to prevent twisting of the inflatable curtain when the inflatable chamber is inflated.

18. The airbag assembly of claim 17, wherein the inflatable chamber is integrated into a fabric of the inflatable curtain.

19. The airbag assembly of claim 17, wherein the inflatable chamber is fixedly attached to the inflatable curtain.

20. The airbag assembly of claim 17, wherein the inflatable chamber is removably coupled to the inflatable curtain.

21. The airbag assembly of claim 14, wherein the twist prevention device is a mechanical component engaged with the plurality of mounting locations.

22. The airbag assembly of claim 14, wherein the twist prevention device is a stiffening member having a stiffness greater than the inflatable curtain.

23. The airbag assembly of claim 22, wherein the stiffening member is engaged with the mounting locations of the inflatable curtain.

24. The airbag assembly of claim 22, wherein the stiffening member is located outside of the inflatable curtain.

25. The airbag assembly of claim 22, wherein the stiffening member is comprised of multiple portions arrangeable in a non-linear orientation with respect to each other.

26. The airbag assembly of claim 22, wherein the stiffening member has telescoping portions such that a length of the stiffening member is adjustable.
