Abstract

An instrument panel component includes a wall, a first projection, and a second projection. The wall is configured to be supported by the instrument panel. The first and second projections are supported by the wall and extend in a common direction away from the wall. The length of the first projection is different than the length of the second projection and both projections are of a different material than the material of the wall.

First claim

What is claimed is:

1. An instrument panel assembly comprising:
an instrument panel;
an energy absorbing element supported by the instrument panel and including a wall;
a first projection and a second projection each disposed between the wall and the instrument panel, the first and second projections extending in a common direction, the first projection being above the second projection; and
the first projection having a first density and the second projection having a second density different than the first density.

2. The instrument panel assembly as set forth in claim 1 further comprising a base connected to the first and second projections and connected to the wall.

3. The instrument panel assembly as set forth in claim 2 wherein the base is adhered to the wall.

4. The instrument panel assembly as set forth in claim 2 wherein the first and second projections are cantilevered from the base.

5. The instrument panel assembly as set forth in claim 2 wherein the first and second projections are integrally formed with the base.

6. The instrument panel assembly as set forth in claim 1 wherein the first projection includes a receptacle and a plunger, the receptacle defining a cavity and the plunger presenting a tapered surface disposed in the cavity.

7. The instrument panel assembly as set forth in claim 1 wherein the first projection is formed of a first material and the second projection is formed of a second material different than the first material.

8. An instrument panel assembly comprising:
an instrument panel;
an energy absorbing element supported by the instrument panel and including a wall;
a first projection and a second projection each disposed between the wall and the instrument panel, the first and second projections extending in a common direction, the first projection being above the second projection;
the first and second projections being of a different material than a material of the wall;
the first projection has a first density and the second projection has a second density different than the first density; and
a base connected to the first and second projections and connected to the wall, wherein the base is between the wall and the first and second projections.

9. The instrument panel assembly as set forth in claim 8 further comprising a housing defining a chamber and a cover supported by the housing and covering the chamber, wherein the wall is a part of the housing.

10. The instrument panel assembly as set forth in claim 8 wherein the base is adhered to the wall.

11. The instrument panel assembly as set forth in claim 8 wherein the first and second projections are cantilevered from the base.

12. The instrument panel assembly as set forth in claim 8 wherein the first and second projections are integrally formed with the base.

13. The instrument panel assembly as set forth in claim 8 wherein the first projection has a first length and the second projection has a second length different than the first length.

14. The instrument panel assembly as set forth in claim 13 wherein the first projection and the second projection are designed such that the first projection, and not the second projection, contacts the instrument panel and deforms upon application of a first amount of force to the energy absorbing element, and such that the first projection and the second projection contact the instrument panel and deform upon application of a second amount of force to the energy absorbing element, the second amount of force being greater than the first amount of force.

15. The instrument panel assembly as set forth in claim 14 , wherein the first amount of force is based on a 5th percentile female, and the second amount of force is based on 95th percentile male.

16. The instrument panel assembly as set forth in claim 8 wherein the first projection extends along an axis and includes ribs spaced from each other along the axis.

17. The instrument panel assembly as set forth in claim 8 wherein the first projection includes a receptacle and a plunger, the receptacle defining a cavity and the plunger presenting a tapered surface disposed in the cavity.

18. The instrument panel as set forth in claim 8 wherein the first projection has a first material and the second projection has a second material different than the first material.
