Abstract

Methods, apparatus, systems and articles of manufacture are disclosed for a standoff to be coupled to a telescoping steering column, the standoff configured to be mounted adjacent an end stop opening in the steering column and to prevent a flexible cover mounted above the steering column from entering the end stop opening.

First claim

What is claimed is:

1. An apparatus comprising:
a telescoping steering column having an end stop opening;
a shroud extending over a portion of the end stop opening;
a flexible cover coupled to the shroud and extending toward the end stop opening;
a standoff coupled to the steering column adjacent the end stop opening, the standoff configured to prevent the cover from entering the end stop opening; and
a lever arm configured to breakaway the standoff from the steering column in response to a stroke event of the steering column.

2. The apparatus of claim 1 , wherein a first portion of the standoff extends away from the steering column.

3. The apparatus of claim 2 , wherein the standoff includes a second portion extending away from the first portion of the standoff, the second portion of the standoff configured to cover the end stop opening of the steering column, the second portion of the standoff integrally formed to a distal end of the first portion of the standoff.

4. The apparatus of claim 2 , wherein breakaway of the first portion of the standoff occurs in response to a shearing of the first portion of the standoff.

5. The apparatus of claim 4 , wherein the first portion of the standoff defines a tapered aperture, the tapered aperture to engage a wedge at impact to cause the shearing of the first portion of the standoff.

6. The apparatus of claim 1 , wherein the standoff is composed of a plastic material.

7. An apparatus comprising:
a telescoping steering column having an end stop opening;
a flexible cover mounted above the steering column and extending toward the end stop opening;
a standoff coupled to the steering column adjacent the end stop, the standoff configured to prevent the flexible cover from entering the end stop opening; and
a lever arm configured to separate the standoff from the steering column in response to a stroke event of the steering column.

8. The apparatus of claim 7 , wherein the standoff includes a first portion extending away from the steering column when the standoff is mounted to the steering column.

9. The apparatus of claim 8 , wherein the standoff includes a second portion integrally formed to a distal end of the first portion of the standoff, the second portion of the standoff extending away from the first portion of the standoff, the second portion of the standoff configured to cover the end stop opening of the steering column when the standoff is mounted to the steering column.

10. The apparatus of claim 8 , wherein the first portion of the standoff defines an aperture configured to receive a portion of the lever arm at impact to cause the first portion of the standoff to separate from the steering column.

11. The apparatus of claim 7 , wherein the standoff is coupled to the steering column by a fastener or a press fit.

12. An apparatus comprising:
a telescoping steering column including an upwardly facing end stop opening;
a rigid shroud extending over a portion of the steering column;
a flexible cover coupled to the shroud and extending toward the end stop opening;
a standoff positioned between the cover and the steering column to prevent the cover from entering the end stop opening; and
a lever arm to breakaway the standoff as a result of a stroke event of the steering column.

13. The apparatus of claim 12 , wherein a first portion of the standoff extends away from an axis of the steering column.

14. The apparatus of claim 13 , wherein a second portion of the standoff, integrally formed to a distal end of the first portion of the standoff, extends along the steering column to cover the end stop opening.

15. The apparatus of claim 13 , wherein the first portion of the standoff defines an aperture, the aperture extending along an axis substantially parallel to the axis of the steering column, the aperture having a taper aligned substantially parallel with a taper of a wedge of the lever arm, the wedge to engage the aperture at impact to cause breakaway of the first portion of the standoff.

16. The apparatus of claim 12 , wherein the standoff is positioned adjacent to the end stop opening.

17. The apparatus of claim 12 , wherein the standoff and the steering column are unitary.

18. An apparatus comprising:
a standoff coupled to a steering column, the standoff positioned adjacent an upwardly facing opening formed in the steering column, the opening associated with a telescoping operation of the steering column, the standoff configured to prevent a flexible cover located above the opening from entering the opening, the standoff including a first portion extending away from the steering column, the first portion defining a tapered aperture; and
a lever arm configured to breakaway the first portion of the standoff from the steering column in response to a stroke event of the steering column, the lever arm including a wedge configured to engage the tapered aperture to cause the first portion to breakaway from the steering column, the breakaway caused by a shearing of the first portion.

19. The apparatus of claim 18 , wherein the standoff further includes a second portion extending away from the first portion of the standoff, the second portion of the standoff configured to cover the opening of the steering column.

20. An apparatus comprising:
a standoff coupled to a telescoping steering column, the standoff mounted adjacent an end stop opening formed in the steering column, the standoff configured to prevent a flexible cover mounted above the steering column from entering the end stop opening, the standoff including a first portion extending away from the steering column, the first portion defining an aperture; and
a lever arm configured to separate the first portion of the standoff from the steering column in response to a stroke event of the steering column, the lever arm including a portion configured to engage the aperture to cause the first portion to separate from the steering column.

21. The apparatus of claim 20 , wherein the standoff further includes a second portion extending away from the first portion of the standoff, the second portion of the standoff configured to cover the end stop opening of the steering column.
