Abstract

An adjustable steering column assembly includes a steering column with an outer jacket moveable along an axis. An instrument panel is coupled to the outer jacket. An instrument panel hood is connected to the instrument panel and the outer jacket. A support bracket includes a pair of support arms including flanges, with a first mounting component and a second mounting component connected to the flanges. The outer jacket is slideably coupled to the first mounting component and the instrument panel is slideably coupled to the second mounting component. The support bracket is pivotable about a pivot axis between an upper limit and a lower limit. A spring is attached to the support bracket for biasing the support bracket toward the upper limit. Coordinated movement between the instrument panel and the outer jacket is possible and the load from the instrument panel is diverted from the outer jacket to the support bracket.

Claims

1. An adjustable steering column assembly for a vehicle, said assembly comprising:

a steering column having an outer jacket moveable along an axis;

an instrument panel coupled to said outer jacket for coordinated movement with said outer jacket along said axis; and

a support bracket having a first mounting component coupled to said outer jacket supporting said outer jacket during said coordinated movement relative to said first mounting component and a second mounting component coupled to said instrument panel supporting said instrument panel independently of said outer jacket during said coordinated movement relative to said second mounting component for alleviating any loads associated with said instrument panel from said outer jacket during said coordinated movement of said instrument panel and said outer jacket.

2. An assembly as set forth in claim 1 wherein said outer jacket is slideably coupled to said first mounting component for movement along said axis.

3. An assembly as set forth in claim 1 wherein said instrument panel is slideably coupled to said second mounting component for movement along said axis.

4. An assembly as set forth in claim 3 including a rail connected between said second mounting component and said instrument panel for slideably coupling said instrument panel to said second mounting component to facilitate said movement along said axis.

5. A assembly as set forth in claim 4 wherein said rail further includes a slide track mounted to said second mounting component and a slide arm slideably connected to said slide track with said instrument panel connected to said slide arm for slideably coupling said instrument panel to said second mounting component.

6. An assembly as set forth in claim 5 including an instrument panel mounting bracket for connecting said instrument panel to said rail.

7. An assembly as set forth in claim 5 including a bracket connecter mounted between said slide arm and said outer jacket for facilitating said coordinated movement of said instrument panel and said outer jacket.

8. An assembly as set forth in claim 1 including an instrument panel hood substantially enclosing said instrument panel and connected to said instrument panel and said outer jacket for facilitating said coordinated movement of said instrument panel with said outer jacket.

9. An assembly as set forth in claim 1 wherein said support bracket further includes a pivot pin defining a pivot axis for coordinated movement of said outer jacket and said instrument panel along said pivot axis between an upper limit and a lower limit.

10. An assembly as set forth in claim 9 including a spring coupled to said support bracket for biasing said support bracket toward said upper limit.

11. An assembly as set forth in claim 1 wherein said first mounting component includes a mounting pin.

12. An assembly as set forth in claim 11 wherein said outer jacket includes a support bracket tab defining a generally elongated slot with said mounting pin disposed within said slot for slideably connecting said outer jacket to said support bracket.

13. An assembly as set forth in claim 12 wherein said first mounting component further includes a retaining ring for retaining said mounting pin in said slot.

14. An assembly as set forth in claim 1 wherein said second mounting component further defines a channel.

15. An assembly as set forth in claim 14 including a rail disposed within said channel of said second mounting component.

16. An assembly as set forth in claim 15 wherein said instrument panel is mounted to said rail for slideably coupling said instrument panel to said support bracket.

17. An assembly as set forth in claim 1 wherein said support bracket further includes a pair of support arms with each of said support arms further including a flange.

18. An assembly as set forth in claim 17 wherein said second mounting component is connected between said flanges.

19. An assembly as set forth in claim 18 wherein said first mounting component is further defined as a pair of first mounting components with one of said first mounting components connected to each said flange extending outwardly from said flanges in different directions from said second mounting component.

20. An assembly as set forth in claim 1 including a locking mechanism coupled to said steering column for preventing said coordinated movement of said outer jacket and said instrument panel.
