Abstract

A mounting mechanism for an inflatable restraint system includes at least one pair of flat mounting members extending from an inflatable restraint module and adapted to extend through at least one pair of apertures in a support structure. The mounting mechanism also includes a bushing disposed over and cooperating with each of the at least one pair of flat mounting members to form a round pin. The mounting mechanism further includes a spring housing adapted to be disposed adjacent the support structure and a spring disposed in the spring housing to engage the flat mounting members to attach the inflatable restraint module to the support structure.

Claims

1. A mounting mechanism for an inflatable restraint system comprising:

at least one pair of flat mounting members extending from an inflatable restraint module and adapted to extend through at least one pair of apertures in a support structure;

a bushing disposed over and cooperating with each of said at least one pair of flat mounting members to form a round pin;

a spring housing adapted to be disposed adjacent the support structure; and

a spring disposed in said spring housing to engage said flat mounting members to attach the inflatable restraint module to the support structure.

2. A mounting mechanism as set forth in claim 1 wherein said bushing has a generally cylindrical main body portion and has a flange at a bottom thereof.

3. A mounting mechanism as set forth in claim 1 wherein said bushing has a tapered distal end and a notch extending generally perpendicular to a longitudinal axis of said bushing.

4. A mounting mechanism as set forth in claim 1 wherein said bushing has a slot extending longitudinally therein to receive one of said at least one pair of flat mounting members.

5. A mounting mechanism as set forth in claim 1 wherein said bushing includes a pair of attachment windows located on opposed sides of said flange.

6. A mounting mechanism as set forth in claim 5 wherein said flat mounting member includes two locking hooks located on opposed sides thereof to cooperate with said attachment windows.

7. A mounting mechanism as set forth in claim 1 wherein said bushing is made of a plastic material.

8. A mounting mechanism as set forth in claim 7 wherein said plastic material contains a lubricant.

9. A mounting mechanism as set forth in claim 1 wherein said flat mounting member has a step thereon to locate said bushing relative to said flat mounting member.

10. A mounting mechanism as set forth in claim 2 wherein each of said at least one pair of flat mounting members has a generally planar main body portion and a widened head portion.

11. A mounting mechanism as set forth in claim 10 wherein said main body portion includes a tapered distal end and a slot elongated in a direction generally perpendicular to a longitudinal axis thereof.

12. An inflatable restraint system for a vehicle comprising:

a steering wheel having a support plate with at least one pair of apertures extending therethrough;

an inflatable restraint module having at least one pair of flat mounting members extending through said at least one pair of apertures; and

a mounting mechanism comprising a bushing disposed over and cooperating with each of said at least one pair of flat mounting members to form a round pin, a spring housing disposed adjacent said support plate, and a spring disposed in said spring housing to engage said flat mounting members to attach said inflatable restraint module to said support plate of said steering wheel.

13. An inflatable restraint system as set forth in claim 12 wherein each of said at least one pair of flat mounting members has a generally planar main body portion and a widened head portion.

14. An inflatable restraint system as set forth in claim 13 wherein said main body portion includes a tapered distal end and a slot elongated in a direction generally perpendicular to a longitudinal axis of said main body portion.

15. An inflatable restraint system as set forth in claim 14 wherein said bushing is generally cylindrical in shape and has a flange at a bottom thereof.

16. An inflatable restraint system as set forth in claim 12 wherein said bushing has a tapered distal end and a notch extending generally perpendicular to a longitudinal axis thereof.

17. An inflatable restraint system as set forth in claim 16 wherein said bushing has a slot extending longitudinally therein to receive on of said at least one pair of flat mounting members.

18. An inflatable restraint system as set forth in claim 16 wherein said flat mounting member includes two locking hooks located on opposed sides thereof.

19. An inflatable restraint system as set forth in claim 18 wherein said bushing includes a pair of attachment windows located on opposed sides of said flange to cooperate with said locking hooks.

20. An inflatable restraint system for a vehicle comprising:

a steering wheel having a support plate with a plurality of apertures extending therethrough;

an inflatable restraint module having a plurality of flat mounting members extending through said apertures, wherein each of said flat mounting members has a generally planar main body portion and a widened head portion, wherein said main body portion includes a tapered distal end and a slot elongated in a direction generally perpendicular to a longitudinal axis of said flat mounting members; and

a mounting mechanism comprising a bushing having a slot extending longitudinally therein to receive one of said flat mounting members to transform said flat mounting members into a round pin, a spring housing disposed adjacent said support structure, and a spring disposed in said spring housing to engage said flat mounting members to attach said inflatable restraint module to said support plate of said steering wheel.
