Abstract

A rest element extends along a transverse direction from a passenger side to an opposite driver side and has a rest surface, which faces in a vertical direction, for a user's hand. A shift element is arranged at a driver-side end of the rest element and between the rest surface and an opposite lower side of the rest element, for operating a shift-by-wire gear selection controller. The shift element is configured to be movable along the transverse direction between a stowage position and a shift position. The shift element is arranged immovably with respect to a longitudinal direction in the stowage position and is mounted movably unidirectionally or bidirectionally in the shift position.

First claim

The invention claimed is:

1. A hand rest device for a motor vehicle having a shift-by-wire gear selection controller, comprising:
a rest element extending along a transverse direction from a passenger side of the hand rest device to a driver side of the hand rest device opposite to the passenger side, having a rest surface facing in a vertical direction and configured to receive a hand of a user; and
a shift element, disposed at a driver-side end of the rest element, between the rest surface and a lower side of the rest element opposite to the rest surface, providing input to the shift-by-wire gear selection controller, the shift element being configured to move along the transverse direction between a stowage position with the shift element substantially recessed in the rest element, and a shift position, in which the shift element projects further out of the rest element than in the stowage position, the shift element being mounted immovably in a longitudinal direction when in the stowage position and movable one of unidirectionally and bidirectionally in the longitudinal direction when in the shift position.

2. The hand rest device as claimed in claim 1 , wherein the shift element includes a push-push lock configured to release the shift element out of the stowage position into the shift position when the shift element is pressed into the rest element, and to hold the shift element in the stowage position after the shift element is pressed in again.

3. The hand rest device as claimed in claim 1 , wherein the shift element includes a finger rest region projecting out of the rest element in the longitudinal direction, at least when the shift element is in the shift position.

4. The hand rest device as claimed in claim 1 , wherein, when the shift element is in the shift position, the shift element is mounted monostably with respect to the longitudinal direction.

5. The hand rest device as claimed in claim 1 , further comprising a shift control providing input to the shift-by-wire gear selection controller when the shift element is in the shift position by responding to a first deflection of the shift element along the longitudinal direction by generating a reverse shift signal indicating selection of a reverse gear and by responding to a second deflection of the shift element along the longitudinal direction, opposite to the first deflection, by generating a forward shift signal indicating selection of a forward automatic gear.

6. The hand rest device as claimed in claim 1 , wherein the driver-side end of the rest element is held only by the rest element and is configured to be graspable by the user.

7. The hand rest device as claimed in claim 1 , further comprising:
a bottom region facing the lower side of the rest element with the rest element extending over the bottom region; and
a screen having a display area configured to display pixel-based display graphics in the bottom region of the hand rest device.

8. The hand rest device as claimed in claim 7 , further comprising a screen control configured to control the screen to display on the display area a gear selection mode set at the shift-by-wire gear selection controller.

9. The hand rest device as claimed in claim 1 ,
further comprising at least one of an additional mechanical button and an operating panel having a touch-sensitive surface, and
wherein, in the shift position, the shift element is only released for movement along the longitudinal direction at least one of after and during actuation of the at least one of the additional mechanical button and the operating panel with the touch-sensitive surface.

10. The hand rest device as claimed in claim 1 , wherein a start-stop function for starting and stopping an engine of the motor vehicle is integrated in the shift element by the hand rest device being configured to keep the engine in a switched-off state in the stowage position of the shift element and to operate the engine in the shift position of the shift element.

11. A motor vehicle, comprising:
a driver seat;
a passenger seat;
a central console between the driver seat and the passenger seat;
a shift-by-wire gear selection controller; and
a hand rest device, disposed in the central console, including
a rest element extending along a transverse direction from a passenger side of the hand rest device to a driver side of the hand rest device opposite to the passenger side, having a rest surface facing in a vertical direction and configured to receive a hand of a user; and
a shift element, disposed at a driver-side end of the rest element, between the rest surface and a lower side of the rest element opposite to the rest surface, providing input to the shift-by-wire gear selection controller, the shift element being configured to move along the transverse direction between a stowage position and a shift position with the shift element substantially recessed in the rest element in the stowage position and the shift element projecting further out of the rest element in the shift position than in the stowage position, the shift element being mounted immovably in a longitudinal direction when in the stowage position and movable one of unidirectionally and bidirectionally in the longitudinal direction when in the shift position.

12. The motor vehicle as claimed in claim 11 , wherein the rest element of the hand rest device is immovable relative to the central console.

13. The motor vehicle as claimed in claim 11 , wherein the shift element includes a push-push lock configured to release the shift element out of the stowage position into the shift position when the shift element is pressed into the rest element, and to hold the shift element in the stowage position after the shift element is pressed in again.

14. The motor vehicle as claimed in claim 13 , wherein, when the shift element is in the shift position, the shift element is mounted monostably with respect to the longitudinal direction.

15. The motor vehicle as claimed in claim 14 , further comprising a shift control providing input to the shift-by-wire gear selection controller when the shift element is in the shift position by generating a reverse shift signal indicating selection of a reverse gear in response to a first deflection of the shift element along the longitudinal direction and by generating a forward shift signal indicating selection of a forward automatic gear in response to a second deflection of the shift element along the longitudinal direction, opposite to the first deflection.

16. The motor vehicle as claimed in claim 15 , wherein the driver-side end of the rest element is held only by the rest element and is configured to be graspable by the user.

17. The motor vehicle as claimed in claim 16 , wherein the hand rest device includes
a bottom region facing the lower side of the rest element with the rest element extending over the bottom region, and
a screen having a display area configured to display pixel-based display graphics in the bottom region of the hand rest device.

18. The motor vehicle as claimed in claim 17 , further comprising a screen control configured to control the screen to display on the display area a gear selection mode set at the shift-by-wire gear selection controller.

19. The motor vehicle as claimed in claim 17 ,
wherein the hand rest device includes at least one of an additional mechanical button and an operating panel having a touch-sensitive surface, and
wherein, in the shift position, the shift element is only released for movement along the longitudinal direction at le
