Abstract

An adjustment lever deceleration assembly for a steering column includes an adjustment lever rotatable between a locked position and an unlocked position. The adjustment lever deceleration assembly also includes a component positioned proximate the adjustment lever, the component rotating at a speed less than a rotational speed of the adjustment lever during adjustment between the locked position to the unlocked position. The adjustment lever deceleration assembly further includes an adjustment lever decelerator integrally formed with the adjustment lever, the adjustment lever decelerator positioned on the adjustment lever to contact the component during rotation of the adjustment lever toward the unlocked position, wherein the adjustment lever deflects and absorbs energy upon contact with the component.

First claim

Having thus described the invention, it is claimed:

1. An adjustment lever deceleration assembly for a steering column comprising:
an adjustment lever rotatable between a locked position and an unlocked position;
a component positioned proximate the adjustment lever, the component being a stationary, non-rotatable portion of a lower jacket of the steering; and
an adjustment lever decelerator integrally formed with the adjustment lever, the adjustment lever decelerator positioned on the adjustment lever to contact the component during rotation of the adjustment lever toward the unlocked position, wherein the adjustment lever deflects and absorbs energy upon contact with the component, the contact between the adjustment decelerator and the component limiting the rotational movement of the adjustment lever, wherein the adjustment lever decelerator is a cantilevered finger extending from an edge of the adjustment lever to a free end of the cantilevered finger.

2. The adjustment lever decelerator assembly of claim 1 , wherein the adjustment lever and the adjustment lever decelerator are a single, molded component.

3. The adjustment lever decelerator assembly of claim 2 , wherein the adjustment lever and the adjustment lever decelerator are a plastic injection molded component.

4. The adjustment lever decelerator assembly of claim 1 , wherein the adjustment lever moves forward in a direction of the steering column during movement toward the unlocked position.

5. The adjustment lever decelerator assembly of claim 1 , wherein the adjustment lever moves rearward in a direction of the steering column during movement toward the unlocked position.

6. The adjustment lever decelerator assembly of claim 1 , wherein the free end of the cantilevered finger contacts the component.

7. The adjustment lever decelerator assembly of claim 1 , wherein an edge of the cantilevered finger contacts the component.

8. A steering column assembly comprising:
a jacket assembly;
an adjustment lever rotatable between a locked position and an unlocked position; and
an adjustment lever decelerator integrally formed with the adjustment lever, the adjustment lever decelerator positioned on the adjustment lever to contact a stationary portion of the jacket assembly during rotation of the adjustment lever toward the unlocked position, wherein the adjustment lever deflects and absorbs energy upon contact with the jacket assembly, the contact between the adjustment decelerator and the component limiting the rotational movement of the adjustment lever, wherein the adjustment lever decelerator is a cantilevered finger extending from an edge of the adjustment lever to a free end of the cantilevered finger.

9. The steering column assembly of claim 8 , wherein the adjustment lever and the adjustment lever decelerator are a single, molded component.

10. The steering column assembly of claim 9 , wherein the adjustment lever and the adjustment lever decelerator are a plastic injection molded component.

11. The steering column assembly of claim 8 , wherein the adjustment lever moves forward in a direction of the steering column assembly during movement toward the unlocked position.

12. The steering column assembly of claim 8 , wherein the adjustment lever moves rearward in a direction of the steering column assembly during movement toward the unlocked position.

13. The steering column assembly of claim 8 , wherein the free end of the cantilevered finger contacts the jacket assembly.

14. The steering column assembly of claim 8 , wherein an edge of the cantilevered finger contacts the jacket assembly.
