Abstract

A steering wheel assembly (10) contains a dampening system for mitigating vibrations transferred from a vehicle to the steering wheel assembly (10). A plurality of damper spring elements or grommets or damper spring elements (22) are each retained within a corresponding steering wheel support member (330). An air bag module (14) is fixed to a steering wheel (18) while resting upon the damper spring elements (22) for eliminating and/or reducing lateral displacement/vibrations normally attendant to vehicle operation. A horn switch (16) containing a plurality of annular support members (76, 176) may be positioned over the damper spring elements (22), wherein each annular support member (76, 176) is coaxially aligned and positioned over a corresponding grommet (22) to also manage vertical displacement; the air bag module (14) is then fixed over the horn switch 16 and to the steering wheel (18). Movement of the airbag module can actuate the horn switch.

First claim

What is claimed is:

1. An assembly comprising:
a steering wheel including a plurality of support members;
a plurality of damper spring elements or grommets, each damper spring element or grommet retained within a corresponding one of said plurality of support members;
an automotive component fixed to said steering wheel and positioned upon said plurality of damper spring elements or grommets;
a plurality of mounting members extending from said automotive component to secure said automotive component to said steering wheel;
an attachment mechanism retainer wire fixed to said plurality of support members, wherein said plurality of mounting members are fixed to said attachment mechanism retainer wire, for fixing said automotive component to said steering wheel; and
a horn switch seated upon said plurality of damper spring elements or grommets, and retained between said plurality of damper spring elements or grommets and said automotive component.

2. The assembly of claim 1 wherein each mounting member is extending through a respective one of said plurality of support members and is fixed to said steering wheel.

3. The assembly of claim 1 wherein said automotive component is an airbag module.

4. The assembly of claim 1 further comprising:
a plurality of damper spring isolators or spacers, each of said isolators or spacers positioned between the attachment mechanism retainer wire and a corresponding damper spring element or grommet.

5. The assembly of claim 1 further comprising:
an inner annular surface contained within each support member;
a rib formed on a median portion of each of said inner annular surfaces; and
a groove formed on a median portion of an outer periphery of each damper spring element or grommet, wherein said respective rib is mated with said respective groove to retain each of said damper spring element or grommet within each corresponding support member.

6. An assembly comprising:
a steering wheel including a first plurality of annular support members;
a plurality of annular damper spring elements or grommets, each damper spring element or grommet retained within a corresponding one of said first plurality of annular support members;
a horn switch assembly containing an upper switch housing and a lower switch housing, the lower switch housing including a second set of annular support members, wherein each one of the second set of annular support members is fixed over and coaxially aligned with a corresponding one of said plurality of annular damper spring elements or grommets;
an automotive component positioned over said horn switch containing a plurality of mounting members, each mounting member fixed to said steering wheel to secure said automotive component to said steering wheel; and
an attachment mechanism retainer wire fixed to said plurality of support members, wherein each of said plurality of mounting members are fixed to said attachment mechanism retainer wire, for fixing said automotive component to said steering wheel.

7. The assembly of claim 6 wherein said automotive component is an airbag module.

8. The assembly of claim 6 further comprising:
a plurality of damper spring isolators or spacers, each of said isolators or spacers positioned between said lower horn switch housing and a corresponding damper spring element or grommet.

9. An assembly comprising:
a steering wheel including a plurality of hollow support members;
a plurality of damper spring elements or grommets, each damper spring element or grommet retained within a corresponding one of said plurality of hollow support members;
an automotive component fixed to said steering wheel and suspended upon said plurality of damper spring elements or grommets;
a plurality of mounting members extending from said automotive component to secure said automotive component to said steering wheel; and
an attachment mechanism retainer wire biased against said plurality of hollow support members, wherein each of said plurality of mounting members are fixed to said attachment mechanism retainer wire, for fixing said automotive component to said steering wheel.

10. The assembly of claim 9 wherein each mounting member is extending through a corresponding one of said plurality of hollow support members and is fixed to said steering wheel.

11. The assembly of claim 9 further comprising:
a horn switch seated upon said plurality of damper spring elements or grommets, and retained between said plurality of damper spring elements or grommets and said automotive component.

12. The assembly of claim 11 further comprising:
a plurality of damper spring element isolators or spacers, each of said isolators or spacers positioned between a lower horn switch housing and a corresponding damper spring element or grommet.

13. The assembly of claim 9 wherein said automotive component is an airbag module.

14. The assembly of claim 9 wherein said plurality of damper spring elements or grommets comprise a plurality of damper springs.

15. The assembly of claim 9 wherein each of said plurality of hollow support members has an annular surface, and each of said damper spring elements or grommets have a corresponding circumferential periphery for mating with one of said annular surfaces.

16. The assembly of claim 15 further comprising:
an inwardly radially extending ledge or rib formed on each of said annular surfaces; and
an inwardly radially extending groove formed on each of said circumferential peripheries for mating with one of said inwardly radially extending ledges or ribs, thereby retaining a respective one of said plurality of damper spring elements or grommets within a corresponding one of said plurality of hollow support members.
