Abstract

An adjustment mounting bracket assembly for a steering column includes a mounting bracket mountable to a steering column mating element, the mounting bracket having a bracket aperture configured to receive a clamp bolt therethrough, the mounting bracket also having an arcuate slot. The bracket assembly also includes a spacer having a spacer aperture configured to receive the clamp bolt therethrough to align the spacer with the mounting bracket, the spacer having a first engaging feature disposed within the arcuate slot of the mounting bracket and a second engaging feature engageable with a recess of the steering column, disposal of the first engaging feature within the arcuate slot and disposal of the second engaging feature within the recess restricting the degree of freedom of the mounting bracket relative to the steering column.

First claim

Having thus described the invention, it is claimed:

1. An adjustment mounting bracket assembly for a steering column comprising:
a mounting bracket mountable to a steering column mating element, the mounting bracket having a bracket aperture configured to receive a clamp bolt therethrough, the mounting bracket also having an arcuate slot; and
a spacer having a spacer aperture configured to receive the clamp bolt therethrough to align the spacer with the mounting bracket, the spacer having a first engaging feature disposed within the arcuate slot of the mounting bracket and a second engaging feature engageable with a recess of the steering column mating element, disposal of the first engaging feature within the arcuate slot and disposal of the second engaging feature within the recess restricting the degree of freedom of the mounting bracket relative to the steering column.

2. The adjustment mounting bracket assembly of claim 1 , wherein the spacer includes a plurality of engaging features disposed within the arcuate slot.

3. The adjustment mounting bracket assembly of claim 1 , wherein the curvature of the arcuate slot corresponds to a rake adjustment axis of the steering column.

4. The adjustment mounting bracket assembly of claim 1 , wherein the arcuate slot is defined by an innermost wall of the mounting bracket.

5. The adjustment mounting bracket assembly of claim 1 , wherein the arcuate slot is defined by an outer wall of the mounting bracket.

6. The adjustment mounting bracket assembly of claim 1 , wherein the recess of the steering column mating element is located at an end of a lower jacket of the steering column.

7. The adjustment mounting bracket assembly of claim 6 , wherein the end of the lower jacket is the end of the lower jacket configured to be closest to a driver.

8. The adjustment mounting bracket assembly of claim 1 , wherein the steering column mating element is a lower jacket of the steering column.

9. A steering column assembly comprising:
a lower jacket, the lower jacket having a recess located at an end of the lower jacket;
an upper jacket telescopingly engaged with the lower jacket in an axial direction;
a clamp bolt extending through the lower jacket in a transverse direction;
a mounting bracket mounted to the lower jacket, the mounting bracket having a bracket aperture configured to receive the clamp bolt therethrough, the mounting bracket also having an arcuate slot; and
a spacer having a spacer aperture configured to receive the clamp bolt therethrough, the spacer having a first engaging feature disposed within the arcuate slot of the mounting bracket and a second engaging feature engageable with the recess of the lower jacket, disposal of the first engaging feature within the arcuate slot and disposal of the second engaging feature within the recess restricting the degree of freedom of the mounting bracket relative to the steering column.

10. The steering column assembly of claim 9 , wherein the spacer includes a plurality of engaging features disposed within the arcuate slot.

11. The steering column assembly of claim 9 , wherein the curvature of the arcuate slot corresponds to a rake adjustment axis of the steering column.

12. The steering column assembly of claim 9 , wherein the arcuate slot is defined by an innermost wall of the mounting bracket.

13. The steering column assembly of claim 9 , wherein the arcuate slot is defined by an outer wall of the mounting bracket.

14. The steering column assembly of claim 9 , wherein the end of the lower jacket is the end of the lower jacket configured to be closest to a driver.

15. A method of controlling an orientation of a mounting bracket relative to a steering column prior to installation of the steering column into a vehicle comprising:
coupling the mounting bracket to a steering column mating element;
disposing a spacer along an outer wall of the mounting bracket, the spacer having a spacer aperture configured to receive a clamp bolt therethrough to align the spacer with the mounting bracket;
disposing a first engaging feature of the spacer within an arcuate slot of the mounting bracket; and
disposing a second engaging feature of the spacer within a recess of the steering column mating element, wherein disposal of the first engaging feature within the arcuate slot and the second engaging feature within the recess restricts the degree of freedom of the mounting bracket relative to the steering column.

16. The method of claim 15 , further comprising disposing a plurality of engaging feature within the arcuate slot.

17. The method of claim 15 , wherein the steering column mating element comprises a lower jacket of the steering column.
