Abstract

The operating device (10) for a vehicle is provided with a housing (12) having a front wall (14). On the front wall (14) there is at least one operating element (18) which can be operated manually starting from an initial position for the purpose of inputting a command or activating a function. The operating element (18) has associated therewith a switch (32) having a switching member (36) upon which the operating key acts when manually operated. A supporting element (24) is also situated in the housing (12) at a distance from the operating element (18), on which supporting element (24) the switch (32) associated with the operating element (18) is situated, wherein the supporting element (24) has a flexible bar (40) having an upper surface (42) facing the operating element (18) and a lower surface (44) facing away from the upper surface (42), and the switch (32) is situated on the flexible bar. Finally, the operating device (10) is provided with an adjustment member (46) which acts upon the flexible bar (40) to adjust the bending position of the flexible bar (40) relative to the operating element (18) in the initial position thereof and to maintain and thus stabilize the flexible bar (40) in the adjusted bending position thereof when the operating element (18) acts upon the switching member (36).

First claim

The invention claimed is:

1. An operating device for a vehicle, comprising:
a housing having a front wall,
at least one operating element which, starting from an initial position, is adapted to be manually actuated for inputting a command or for activating a function,
a switch associated with the operating element and having a switching member upon which the operating element acts when being manually actuated,
a supporting element arranged in the housing at a distance to the operating element,
wherein the supporting element comprises a flexible bar having an upper side facing the operating element and a lower side facing away from the upper side,
wherein the switch associated with the operating element is arranged at the flexible bar, and
an adjustment member acting upon the flexible bar for adjusting the bending position of the flexible bar relative to the operating element in its initial position and for keeping and thus stabilizing the flexible bar in its adjusted bending position when the operating element acts upon the switching member.

2. The operating device according to claim 1 , wherein the switch comprises a switching member adapted to be moved by the operating element along a stroke up to a switch triggering position, and that the flexible bar is adapted to be both displaced into a bending position by means of the adjustment member and fixed in said bending position, wherein, in the bending position, the stroke has a presettable length, in consideration of compensation of manufacturing and/or of assembly tolerances of the housing, of the operating element and of the switch.

3. The operating device according to claim 2 , wherein the adjustment member is configured as an adjustment screw having a threaded shaft and which is in threading engagement with a reference element positioned relative to the flexible bar of the supporting element, and that by turning the adjustment screw the flexible bar is adapted to be bent.

4. The operating device according to claim 2 , wherein the adjustment member is configured as an adjustment screw having a threaded shaft and which is axially held in a turnable manner at a reference element positioned relative to the flexible bar of the supporting element, that the threaded shaft of the adjustment screw is in threading engagement with the flexible bar, and that, when the adjustment screw is turned, the flexible bar is adapted to be bent.

5. The operating device according to claim 2 , wherein the adjustment member acts upon the flexible bar at a position arranged in alignment with the extension of the moving axis, extending through the switch, of the operating element of the switching member when the latter is actuated.

6. The operating device according to claim 2 , wherein the switch is arranged on the upper side of the flexible bar facing the operating element, and that the adjustment screw rests upon the lower side of the flexible bar facing away from the upper side and in a manner flush with the switch.

7. The operating device according to claim 2 , wherein an electrically or electromechanically or electromagnetically operating feedback unit for a tactile feedback of a valid manual actuation of the operating element.

8. The operating device according to claim 1 , wherein the adjustment member is configured as an adjustment screw having a threaded shaft and which is in threading engagement with a reference element positioned relative to the flexible bar of the supporting element, and that by turning the adjustment screw the flexible bar is adapted to be bent.

9. The operating device according to claim 1 , wherein the adjustment member is configured as an adjustment screw having a threaded shaft and which is axially held in a turnable manner at a reference element positioned relative to the flexible bar of the supporting element, that the threaded shaft of the adjustment screw is in threading engagement with the flexible bar, and that, when the adjustment screw is turned, the flexible bar is adapted to be bent.

10. The operating device according to claim 1 , wherein the switch comprises at least two contacts electrically connected in a switch triggering position, or that the switch is configured as a path sensor which operates in an optical, capacitive, resistive or inductive manner.

11. The operating device according to claim 1 , wherein the adjustment member acts upon the flexible bar at a position arranged in alignment with the extension of the moving axis, extending through the switch, of the operating element of the switching member when the latter is actuated.

12. The operating device according to claim 1 , wherein the switch is arranged on the upper side of the flexible bar facing the operating element, and that the adjustment screw rests upon the lower side of the flexible bar facing away from the upper side and in a manner flush with the switch.

13. The operating device according to claim 1 , wherein an electrically or electromechanically or electromagnetically operating feedback unit for a tactile feedback of a valid manual actuation of the operating element.
