Abstract

The invention relates to a switching-operation arrangement for a motor vehicle, having a movable actuating surface. The actuating surface has an extent along a first axis and a second axis, which are located perpendicularly to one another. The actuating surface interacts with a displacement means such that the actuating surface can be moved linearly, in the direction of a third axis (z), by at least one distance from a starting position into an actuating position, the third axis (z) being located perpendicularly to the first and second axes. The actuating position is in the form of a switching position and acts with switching action on a switching element or a sensor. The displacement means includes a guide means for guiding the actuating surface along the first axis and at least one braced-in elastic element for guiding the actuating surface along the second axis.

First claim

The invention claimed is:

1. A switching-operation arrangement for a motor vehicle, comprising: a movable actuating surface; a displacement means; and one of a switching element and a sensor, wherein the actuating surface has an extent along a first axis (x) and a second axis (y), which are located perpendicularly to one another, wherein the actuating surface interacts with the displacement means such that the actuating surface can be moved linearly, in the direction of a third axis (z), by at least one distance from a starting position into an actuating position, wherein the third axis (z) is located perpendicularly to the first and second axes (x, y), and wherein the actuating position is in the form of a switching position such that the actuating surface, in the switching position, acts with switching action on the one of the switching element and the sensor, wherein the displacement means comprises a guide means for guiding the actuating surface at least one of along and on the first axis (x), and at least one braced-in elastic element for guiding the actuating surface at least one of along and on the second axis (y).

2. The switching-operation arrangement according to claim 1 , wherein one of a length and a width of the actuating surface along at least one of the first two axes (x and/or y) is greater than a distance over which guidance is effected by the displacement means to provide for the movement capability of the actuating surface in the direction of the third axis (z).

3. The switching-operation arrangement according to claim 1 , wherein the elastic element is configured to have a surface and a thickness, such that the elastic element can be elastically deflected perpendicularly to the surface of the elastic element.

4. The switching-operation arrangement according to claim 1 , wherein the displacement means further comprises an actuator, the actuator interacts with at least one of a frame and a spacer, the elastic element is braced on at least one of the frame and the spacer, and the frame is connected to the spacer by means of the elastic element.

5. The switching-operation arrangement according to claim 4 , wherein the spacer is fastened on the actuator by means of a screw connection.

6. The switching-operation arrangement according to claim 1 , wherein the guide means comprises a guide rib and a groove, which interacts with the guide rib, and one of the guide rib and the groove of the guide means is provided on the actuator and the other of the guide rib and the groove of the guide means is provided on the frame.

7. The switching-operation arrangement according to claim 1 , wherein the elastic element comprises one of a stiff plastic sheet and a thin plastic plate.

8. The switching-operation arrangement according to claim 1 , wherein the one of the switching element and the sensor generates a signal on account of the switching action of the actuating surface in the switching position, and the signal serves for at least one of switching and triggering a function of a switching signal.

9. The switching-operation arrangement according to claim 1 , wherein a housing is provided, and the actuating surface is arranged on one side of the housing and can be moved in the direction of the housing.

10. The switching-operation arrangement according to claim 1 , wherein the switching-operation arrangement is a short-stroke button.

11. The switching-operation arrangement according to claim 3 , wherein the thickness of the elastic element is smaller than an extent of the elastic element.

12. The switching-operation arrangement according to claim 4 , wherein the elastic element comprises two parallel elastic elements, which are arranged on mutually opposite sides of at least one of the frame and the spacer.

13. The switching-operation arrangement according to claim 1 , wherein the extent of the actuating surface along the first axis (x) is one of smaller and greater than the extent of the actuating surface along the second axis (y).

14. The switching-operation arrangement according to claim 2 , wherein the movement capability of the actuating surface in the direction of the third axis (z) is free of tilting in relation to the first two axes (x and/or y).

15. The switching-operation arrangement according to claim 5 , wherein the actuating surface is arranged on the actuator, and the actuating surface is mounted as a cap on the actuator.

16. The switching-operation arrangement according to claim 7 , wherein the elastic element is fastened in a braced-in state on at least one of the frame and the spacer, and fastening of the elastic element is effected by means of at least one of welding, adhesive bonding, riveting, screw connection, heat staking/hot stamping, and clamping.
