Abstract

The invention relates to a shift operating element, specifically for a motor vehicle, having an actuation surface which can be moved by the manual application of force by means of an element, wherein the element is specifically the finger of a human hand. The shift operating element comprises a sensor which interacts with the actuation surface such that the sensor, upon the movement of the actuation surface by means of the element, generates a signal. The signal is specifically employed to shift and/or trigger a function, in the manner of a shift signal. A mechanical damping and/or restoring element is provided which interacts with the actuation surface upon the movement thereof. The mechanical damping and/or restoring element is a constituent of the sensor, specifically the mechanical damping and/or restoring element is integrated into the sensor.

First claim

The invention claimed is:

1. A shift operating element having an actuation surface which can be moved by manual application of force by a finger of a human hand, and having a sensor which interacts with the actuation surface such that the sensor, upon the movement of the actuation surface by the finger of the human hand, generates a signal, wherein the signal is employed to shift and/or trigger a function, in a manner of a shift signal, wherein a damping and/or restoring element is provided, which interacts with an actuation element arranged on the actuation surface upon the movement thereof, wherein the damping and/or restoring element is a constituent of the sensor and the damping and/or restoring element has a connecting surface comprising elastic spring arms, wherein, on the spring arms, two approximately centrally arranged, mutually opposing and approximately rectangular surfaces are arranged for interaction with the actuation element wherein the rectangular surfaces constitute a first sensor electrode, and wherein a nub is configured on the rectangular surfaces, for interaction with a stud on the actuation element.

2. The shift operating element as claimed in claim 1 , wherein the actuation element acts on the damping and/or restoring element, wherein the damping and/or restoring element, upon the application of force to the actuation surface, moves in an approximately plane-parallel manner, and wherein upon the movement of the actuation surface, the actuation element can interact with the damping and/or restoring element in order to generate a signal.

3. The shift operating element as claimed in claim 1 , wherein the damping and/or restoring element functions as the first sensor electrode for the sensor, wherein a further second sensor electrode is provided for the sensor, such that the two sensor electrodes constitute a capacitive sensor, and wherein the variation in the mutual clearance between the two sensor electrodes, associated with the movement of the damping and/or restoring element, alters the capacitance of the sensor, wherein the variation in the capacitance of the sensor is then employed to generate the signal.

4. The shift operating element as claimed in claim 3 , further comprising a circuit board, wherein the damping and/or restoring element is fitted to and/or arranged on the circuit board, wherein the damping and/or restoring element is electrically contacted with the circuit board to constitute the first sensor electrode, wherein the second sensor electrode is constituted by printed conductors in the form of copper surfaces, on the circuit board, and wherein the first sensor electrode on the damping and/or restoring element, by the application of force on the actuation surface, moves in an approximately plane-parallel manner to the second sensor electrode on the circuit board.

5. The shift operating element as claimed in claim 1 , wherein the damping and/or restoring element is a mechanical damping and/or restoring element.

6. The shift operating element as claimed in claim 1 , wherein the damping and/or restoring element is configured as an elastic element in the form of a leaf-spring spring element, wherein the elastic element incorporates in the connecting surface contact surfaces of an approximately H-shaped design, for the purposes of electrical contacting with a circuit board.

7. The shift operating element as claimed in claim 1 , wherein the damping and/or restoring element is comprised of a metal, and wherein the damping and/or restoring element is manufactured in the form of a stamped and bent part.

8. The shift operating element as claimed in claim 1 , further comprising a housing, wherein the actuation surface constitutes a substantially closed surface of the housing, and wherein the damping and/or restoring element and/or a circuit board are arranged in the interior of the housing.

9. The shift operating element as claimed in claim 1 , wherein the damping and/or restoring element is a constituent of an inductive sensor, a magnetic sensor, or a Hall type sensor.

10. A shift operating element according to claim 1 for a motor vehicle.

11. The shift operating element as claimed in claim 1 , wherein a mechanical damping and/or restoring element is integrated into the sensor and/or the sensor is integrated into the damping and/or restoring element.
