Abstract

The present invention relates to a motor-operated component, in particular in or for a motor vehicle, which comprises at least in regions a material which is permeable to an electric field, and which comprises a sensor-controlled anti-trapping apparatus which contains at least one electrically conductive first sensor electrode which is arranged in the interior of the component in a region which comprises the material which is permeable to electric fields, and which is inaccessible from outside the component.

Claims

1. A motor-operated component, in particular in or for a motor vehicle,

which motor-operated component has, at least in regions, a material which is permeable for an electric field, and

which motor-operated component has a sensor-controlled anti-trapping apparatus which comprises at least one electrically conductive first sensor electrode which is arranged in the interior of the component in a region which has a material, which is permeable for electric fields, and is inaccessible from an outer side of the component.

2. The component of claim 1, characterized in that the anti-trapping apparatus has a contactless proximity sensor, in particular a capacitive sensor.

3. The component of claim 2, characterized in that the proximity sensor has at least one first sensor electrode which is arranged within the component and at least one second sensor electrode which is arranged so as to lie substantially opposite the first sensor electrode when the component is closed.

4. The component of claim 1, characterized in that the first sensor electrode is arranged in a region of the component, the outer face of which is accessible from the outside only in the open state of the component.

5. The component of claim 1, characterized in that the first sensor electrode is arranged in the interior of the component along its edge at risk of trapping.

6. The component of claim 1, characterized in that the first sensor electrode is arranged in a region of the component which has the material which is permeable for the electric field.

7. The component of claim 1, characterized in that the component has an outer face which is accessible from the outside in the open state of the component and an inner face which is provided on a side of the component which faces away from the outer face, the first sensor electrode being arranged on the inner face of the component.

8. The component of claim 1, characterized in that the first sensor electrode is formed by an electrically conductive region within that material of the component which is permeable for electric fields.

9. The component of claim 1, characterized in that the sensor electrode is configured as a conductive coating and/or as a conductive wire electrode and/or as a conductive foil and/or as a conductive sheet metal part.

10. The component of claim 1, characterized in that the sensor electrode is fastened on an inner face of the component by means of an adhesive layer and/or by means of a clip closure and/or by means of a screw connection.

11. The component of claim 1, characterized in that the sensor electrode is embossed and/or pressed into an inner face of the component and/or is vapor-deposited directly onto an inner face of the component.

12. The component of claim 1, characterized in that that material of the component which is permeable for electric fields is plastic.

13. The component of claim 1, characterized in that the component is configured as a tailgate, as a trunk lid, as a sliding door, as a side door and/or as a tilting/sliding roof of a motor vehicle.

14. The component of claim 1, characterized in that the anti-trapping apparatus has a control device which evaluates sensor signals of the sensor electrode and controls the means for protecting against trapping as a function of the evaluation.

15. The component of claim 14, characterized in that the control device is arranged within the component.

16. The component of claim 14, characterized in that the control device is arranged on an inner face of the component and/or in that material of the component which is permeable for the electric field.

17. The component of claim 14, characterized in that the control device is attached without shielding on the side of the first sensor electrode.

18. The component of claim 14, characterized in that the control device is connected to the first sensor electrode via a flat contact.

19. The component of claim 14, characterized in that the control device is a constituent part of a control unit for controlling the opening and/or closing operation of the component.

20. The component of claim 14, characterized in that the motor-operated component moves as a function of a control operation of the control device, the drive motor acting on an adjusting mechanism for an opening and/or closing operation of the component, and the component being connected to this adjusting mechanism via a driver.
