Abstract

A steering column assembly includes a jacket assembly, a mounting bracket, and a first telescope guide. The jacket assembly defines a first guide slot. The mounting bracket is disposed on the jacket assembly and has a first portion disposed opposite a second portion and a third portion extending between the first portion and the second portion. The first portion has a first rail received within the first guide slot. The first telescope guide is disposed between the first guide slot and the first rail.

First claim

What is claimed is:

1. A steering column assembly comprising:
a jacket assembly defining a first guide slot;
a mounting bracket disposed on the jacket assembly, the mounting bracket having a first portion disposed opposite a second portion and a third portion extending between the first portion and the second portion, the first portion having a first rail received within the first guide slot; and
a first telescope guide disposed between the first guide slot and the first rail.

2. The steering column assembly of claim 1 , wherein the first guide slot is disposed between a first jacket lip and a first jacket stiffness rail.

3. The steering column assembly of claim 1 , wherein the first telescope guide has a first wall disposed opposite a second wall and a third wall extending between the first wall and the second wall.

4. The steering column assembly of claim 3 , wherein the first rail has a first surface disposed opposite a second surface and an engagement surface extending between the first surface and the second surface.

5. The steering column assembly of claim 4 , wherein the first wall is disposed substantially parallel to the first surface and the second wall is disposed substantially parallel to the second surface.

6. The steering column assembly of claim 4 , further comprising a plastic component injected within a cavity formed by the first telescope guide and the first rail.

7. The steering column assembly of claim 6 , wherein the plastic component engages at least a portion of the first wall, the second wall, the third wall, the first surface, the second surface, and the engagement surface.

8. The steering column assembly of claim 7 , wherein the plastic component fixedly positions the first telescope guide relative to the first rail.

9. A steering column assembly comprising:
a jacket assembly having a body, a central element extending from the body, and a support portion disposed on the central element, the body, the central element, and the support portion defines a first guide slot and a second guide slot disposed opposite the first guide slot;
a mounting bracket having a first portion disposed opposite a second portion, the first portion having a first rail configured to be received within the first guide slot and the second portion having a second rail configured to be received within the second guide slot;
a first telescope guide disposed between the first guide slot and the first rail; and
a second telescope guide disposed between the second guide slot and the second rail.

10. The steering column assembly of claim 9 , wherein the first telescope guide has a first wall disposed opposite a second wall and a third wall extending between the first wall and the second wall.

11. The steering column assembly of claim 10 , wherein the third wall has a raised section extending towards a first wall distal end and a second wall distal end.

12. The steering column assembly of claim 11 , wherein the first rail has a first surface disposed opposite a second surface and an engagement surface extending between the first surface and the second surface.

13. The steering column assembly of claim 12 , wherein the engagement surface includes a first segment extending from the first surface towards an intersection point and a second segment extending from the second surface towards the intersection point.

14. The steering column assembly of claim 13 , wherein the raised section extends towards and is spaced apart from the engagement surface.

15. The steering column assembly of claim 9 , further comprising a plastic component injected between the first telescope guide and the first rail.

16. The steering column assembly of claim 15 , further comprising a plastic component injected between the second telescope guide and the second rail.

17. The steering column assembly of claim 16 , wherein during operation of a linear actuator the jacket assembly is configured to translate relative to the mounting bracket along a first bearing surface of the first telescope guide and a second bearing surface of the second telescope guide.

18. A method of manufacturing a steering column assembly comprising:
providing a mounting bracket, the mounting bracket that includes:
a first portion having a first rail;
a second portion disposed opposite the first portion, the second portion having a second rail;
a third portion extending between the first portion and the second portion;

providing a second jacket assembly that receives a first jacket assembly, the second jacket assembly that includes:
a body,
a central element extending from the body, and
a support portion disposed on the central element, the body, the central element, and the support portion defining a first guide slot and a second guide slot;

inserting the second jacket assembly within the mounting bracket such that the first rail is received within the first guide slot and the second rail is received within the second guide slot;
inserting a first telescope guide between the first guide slot and the first rail;
inserting a second telescope guide between the second guide slot and the second rail, each of the first telescope guide and the second telescope guide includes:
a first wall;
a second wall disposed opposite the first wall; and
a third wall extending between a first wall proximal end and a second wall proximal end, the third wall having a raised section extending towards a first wall first end and a second wall first end.

19. The method of claim 18 , further comprising injecting a plastic component between the first telescope guide and the first rail to join the first telescope guide to the first rail.

20. The method of claim 18 , further comprising injecting a plastic component between the second telescope guide and the second rail to join the second telescope guide to the second rail.
