Abstract

A steering wheel assembly includes a steer-by-wire steering wheel and a central axis about which the steering wheel rotates to control the direction of travel of a motor vehicle. The steering wheel assembly also includes (a) a support arm, the steering wheel being coupled to a first end of the support arm so as to permit rotation of the steering wheel about the central axis of the steering wheel and (b) an interior trim portion, wherein the second end of the support arm is slidably coupled to a track of the interior trim portion. The track is configured such that the steering wheel is movable relative to the interior trim portion from a first deployed position in which a first occupant of the vehicle steers the steering wheel to a position away from the first deployed position.

First claim

What is claimed:

1. A steering wheel assembly comprising:
a steer-by-wire steering wheel including a central axis about which the steer-by-wire steering wheel rotates to control direction of travel of a motor vehicle;
a support arm comprising a first end, a second end and a boss at the second end, the steer-by-wire steering wheel being coupled to the first end of the support arm so as to permit rotation of the steer-by-wire steering wheel about the central axis; and
an interior trim portion comprising a track, wherein the track comprises a pair of spaced apart channels either side of an aperture through which the support arm extends, and wherein the boss extends into each of the pair of spaced apart channels,
wherein the second end of the support arm is slidably coupled to the track and the track is configured such that the steer-by-wire steering wheel is movable relative to the interior trim portion from a first deployed position in which a first occupant of the motor vehicle steers the steer-by-wire steering wheel to a position away from the first deployed position, and,
wherein the steer-by-wire steering wheel is movable relative to the interior trim portion from the first deployed position to a stowed position in which the steering wheel is stowed in or on the interior trim portion.

2. The steering wheel assembly of claim 1 , wherein the track comprises a first track portion and the first track portion extends in a longitudinal direction of the motor vehicle.

3. The steering wheel assembly of claim 2 , wherein at least a portion of the track is curved such that the second end of the support arm follows a curved path.

4. The steering wheel assembly of claim 3 , wherein the at least said portion of the track is curved when viewed in a lateral direction.

5. The steering wheel assembly of claim 4 , wherein the track at least partially follows an outer surface of the interior trim portion.

6. The steering wheel assembly of claim 5 , wherein the track extends into an inner space of the interior trim portion.

7. The steering wheel assembly of claim 6 , wherein the interior trim portion further comprises a recess in an underside of the interior trim portion, the recess being configured to receive the steer-by-wire steering wheel.

8. The steering wheel assembly of claim 7 , wherein the steer-by-wire steering wheel is rotatable about a further axis at the first or second end of the support arm, the further axis being orthogonal to the central axis of the steer-by-wire steering wheel.

9. The steering wheel assembly of claim 8 , wherein the steering wheel is movable relative to the interior trim portion from the first deployed position to a second deployed position in which a second occupant of the motor vehicle steers the steer-by-wire steering wheel.

10. The steering wheel assembly of claim 9 , wherein the track comprises a second track portion and the second track portion extends in said lateral direction of the motor vehicle.

11. The steering wheel assembly of claim 1 , wherein the support arm is elongate.

12. The steering wheel assembly of claim 11 , wherein the support arm is curved.

13. The steering wheel assembly of claim 12 , wherein the support arm projects upwards and rearwards from the second end to the first end of the support arm in the first deployed position.

14. The steering wheel assembly of claim 1 , wherein the steering wheel assembly further comprises a selectively releasable lock configured to selectively lock the second end of the support arm relative to the track in the first deployed position.

15. The steering wheel assembly of claim 14 , wherein the steering wheel assembly is configured such that the selectively releasable lock is prevented from unlocking unless the motor vehicle is stationary or the vehicle is in an autonomous mode.

16. The steering wheel assembly of claim 1 , wherein the steering wheel assembly further comprises electrical contacts provided in the track and the second end of the support arm such that at least one of power and data is transmitted to or from the steer-by-wire steering wheel when in the first deployed position.

17. The steering wheel assembly of claim 16 , wherein the steering wheel assembly further comprises sliding electrical contacts provided between the track and the second end of the support arm such that at least one of power and data is transmitted to or from the steer-by-wire steering wheel as the second end of the support arm slides in the track.

18. The steering wheel assembly of claim 1 , wherein the steering wheel assembly further comprises one or more bearings provided between the second end of the support arm and the track.
