Abstract

A steering wheel of a motor vehicle, with a hub arranged parallel to a longitudinal axis, and with a segment of a steering wheel rim comprising a rim portion. The rim portion is attached to the first spoke, which is attached to the hub, and the rim portion is attached to a second spoke, which is attached to the hub in a manner rotatable about a pivot axis running parallel to the longitudinal axis and offset in relation thereto. A steering device of a motor vehicle comprising a steering wheel.

First claim

The invention claimed is:

1. A steering wheel for use in a motor vehicle and configured to rotate about a steering column, the steering wheel comprising:
a hub defining a substantially cylindrical axis arranged parallel to a longitudinal axis defined by the steering column and defining a pivot axis extending parallel to and offset from the longitudinal axis;
a first spoke attached to the hub;
a second spoke; and
a steering wheel rim provided with a segment including a rim portion attached to the first spoke and the second spoke, wherein the second spoke is attached to the hub so that the second spoke is configured to rotate about the hub and pivot about the pivot axis.

2. The steering wheel of claim 1 , wherein the first spoke is rigidly attached to the hub.

3. The steering wheel of claim 2 , wherein the first spoke is molded to the hub.

4. The steering wheel of claim 2 , wherein the first spoke is disposed perpendicular to the longitudinal axis.

5. The steering wheel of claim 1 , wherein the hub defines a first terminal detent configured to engage the second spoke when the second spoke rotates from a first position to a second position.

6. The steering wheel of claim 1 , further comprising:
a locking device configured to lock the second spoke with respect to the hub.

7. The steering wheel of claim 1 , further comprising:
an electromotive adjustment device configured to rotate the second spoke.

8. The steering wheel of claim 1 , wherein the rim portion has an arcuate shape, a first end, attached to the first spoke, and a second end, attached to the second spoke, wherein the first end is opposite the second end.

9. The steering wheel of claim 1 , wherein the steering wheel rim includes a second segment parallel to the first spoke.

10. The steering wheel of claim 1 , further comprising:
a personal protection device disposed in the hub.

11. The steering wheel of claim 1 , wherein the rim portion is mounted with respect to the hub so that the rim portion displaceable along a direction parallel to the longitudinal axis.

12. A steering device for use in a motor vehicle, the steering device comprising:
a steering column defining a longitudinal axis and a pivot axis parallel to and offset from the longitudinal axis;
a hub coupled to the steering column and configured to rotate about the longitudinal axis;
a first spoke attached to the hub;
a second spoke; and
a steering wheel rim provided with a segment including a rim portion attached to the first spoke and the second spoke, wherein the second spoke is attached to and rotatable about the hub and configured to pivot about the pivot axis.

13. A steering wheel for use in a motor vehicle and configured to rotate about a steering column, the steering wheel comprising:
a hub configured to be coupled the steering column and rotate with respect to a longitudinal axis defined by the steering column;
a first segment including,
a first rim portion having an arcuate shape,
a first spoke, and
a second spoke, wherein the first spoke the second spoke each extend between the hub and the first rim portion; and

a second segment including,
a second rim portion having an arcuate shape,
a third spoke, and
a fourth spoke, wherein the third spoke the fourth spoke each extend between the hub and the second rim portion,

wherein the first segment and the second segment are configured to collectively move between a use position and a stowage position, in the use position the first rim portion and the second rim portion are disposed in a common plane and in the stowage position the first rim portion and the second rim portion are spaced apart from one another with respect to and along the longitudinal axis.

14. The steering wheel of claim 13 , wherein the first spoke and the third spoke are each configured to pivot about a pivot point defined by the hub towards the longitudinal axis.

15. The steering wheel of claim 13 , wherein an end of the first rim portion engages an end of the second rim portion when the first segment and the second segment are each in the use position.

16. The steering wheel of claim 13 , wherein the first spoke and the second spoke are each configured to rotate about the hub.

17. The steering wheel of claim 16 , wherein the third spoke and the fourth spoke are each configured to rotate about the hub.

18. The steering wheel of claim 17 , wherein as the first segment and the second segment move from the use position to the stowage position, the second spoke rotates in a first rotational direction and the third spoke rotates in a second rotational direction, wherein the second rotational direction is opposite the first rotational direction.

19. The steering wheel of claim 16 , wherein as the first segment and the second segment move from the use position to the stowage position, the first spoke overlaps the second spoke.

20. The steering wheel of claim 13 , wherein the hub defines a first guide and a second guide each circumferentially extending along at least a portion of the hub, wherein the first guide and the second guide are spaced apart from one another with respect to the longitudinal axis, wherein the first spoke and the second spoke each extend from the first guide and the third spoke and the fourth spoke each extend from the second guide.
