Abstract

An airbag module is provided with a means for securing a leadwire. In one embodiment, the means for securing a leadwire comprises at least one self-closing leadwire clip for securing the leadwire within an airbag housing. As the cover of the airbag housing is closed, the self-closing clip(s) close and secure the leadwire in place.

Claims

1. An airbag apparatus for a motor vehicle, comprising:

an airbag housing connected to an airbag housing cover, the airbag housing cover having an open position and a closed position;

a leadwire routed inside the airbag housing; and

at least one self-closing leadwire clip connected to the airbag housing, the self-closing leadwire clip having an open configuration and a closed configuration, wherein the open configuration of the self-closing leadwire clip corresponds to the open position of the airbag housing cover, wherein the closed configuration of the self-closing leadwire clip corresponds to the closed position of the airbag housing cover, and wherein the self-closing leadwire clip is configured to accept the leadwire in the open configuration and to secure the leadwire in the closed configuration.

2. The airbag apparatus of claim 1, wherein the at least one self-closing leadwire clip is integral with the airbag housing.

3. The airbag apparatus of claim 1, further comprising at least one inspection window permitting visual inspection of the leadwire from outside of the airbag housing while the airbag housing cover is in the closed position.

4. The airbag apparatus of claim 3, wherein the at least one self-closing leadwire clip and the at least one inspection window are integral with the airbag housing.

5. The airbag apparatus of claim 1, wherein the at least one self-closing clip comprises a clip arm.

6. The airbag apparatus of claim 5, wherein the at least one clip arm comprises a hook connected with the clip arm.

7. The airbag apparatus of claim 1, further comprising a hinge connecting the airbag housing cover to the airbag housing.

8. The airbag apparatus of claim 7, wherein at least a portion of the self-closing clip is connected with the hinge.

9. The airbag apparatus of claim 8, wherein the at least one self-closing leadwire clip comprises a clip arm and a protrusion, and wherein the protrusion is connected with the hinge.

10. The airbag apparatus of claim 1, wherein a plurality of self-closing leadwire clips are connected to the airbag housing and are configured to secure the leadwire in the closed position.

11. An airbag apparatus for a motor vehicle, comprising:

an airbag housing having a leadwire routed inside the airbag housing;

an airbag housing cover having an open position and a closed position;

a hinge connecting the airbag housing to the airbag housing cover; and

at least one self-closing leadwire clip comprising;

a clip arm connected to the airbag housing; and

a protrusion connected to the hinge and positioned to extend in the direction of the clip arm, wherein the clip arm and the protrusion form a gap for accepting the leadwire when the self-closing leadwire clip is in an open configuration, and wherein the at least one self-closing leadwire clip responds to a transition of the airbag housing cover from the open position to the closed position by at least partially closing the gap such that the self-closing leadwire clip is in a closed configuration.

12. The airbag apparatus of claim 11, wherein at least one self-closing clip further comprises a hook extending from the clip arm substantially in the direction of the protrusion.

13. The airbag apparatus of claim 12, wherein the shape of the protrusion is substantially symmetrical to the shape of the hook.

14. The airbag apparatus of claim 11, wherein the at least one self-closing leadwire clip at least partially closes the gap between the protrusion and the clip arm before the airbag housing cover completes the transition from the open position to the closed position.

15. The airbag apparatus of claim 11, wherein the at least one self-closing clip responds to a transition of the airbag housing cover from the open position to the closed position by fully closing the gap.

16. The airbag apparatus of claim 11, further comprising at least one inspection window permitting visual inspection of the leadwire from outside of the airbag housing while the airbag housing cover is in the closed position.

17. The airbag apparatus of claim 16, wherein the at least one inspection window is disposed between the clip arm and the protrusion.

18. An airbag apparatus for a motor vehicle, comprising:

an airbag housing;

an airbag inflator assembly at least partially disposed within the airbag housing;

a leadwire routed inside the airbag housing and connected to the airbag inflator assembly;

an inflatable airbag cushion disposed within the airbag housing and connected to the airbag inflator assembly;

an airbag housing cover having an open position and a closed position;

a hinge connecting the airbag housing to the airbag housing cover; and

a plurality of self-closing leadwire clips, each self-closing leadwire clip having an open configuration and a closed configuration, the open configuration of the self-closing leadwire clip corresponding to the open position of the airbag housing cover, and the closed position of the self-closing leadwire clip corresponding to the closed position of the airbag housing cover, wherein the plurality of self-closing leadwire clips accept the leadwire in the open configuration, and secure the leadwire in the closed configuration.

19. The airbag apparatus of claim 18, further comprising at least one inspection window permitting visual inspection of the leadwire from outside of the airbag housing while the airbag housing cover is in the closed position.

21. The airbag apparatus of claim 19, further comprising means for permitting visual inspection of the leadwire from outside of the housing means while the means for covering the housing means is in the closed position.

20. An airbag apparatus for a motor vehicle, comprising:

means for housing an airbag module;

means for covering the housing means, the means for covering the housing means having an open position and a closed position; and

means for securing a leadwire within the housing means, the means for securing the leadwire accepting the leadwire in an open configuration and securing the leadwire in a closed configuration, wherein the open configuration of the means for securing a leadwire corresponds to the open position of the means for covering the housing means, and wherein the closed configuration of the means for securing a leadwire corresponds to the closed position of the means for covering the housing means.
