Abstract

The object of the present invention is a drive unit for a motor vehicle component with an electromotor ( 5 ) and a rotatable output element ( 7 ). Furthermore, a blocking element ( 9 ), which can be acted on by an actuator ( 10 ), is provided for interacting with a protrusion ( 15 ) on the output element ( 7 ). According to the invention, the protrusion ( 15 ) detaches the blocking element ( 9 ) from a stop ( 17 ) at the start of a rotational movement of the output element ( 7 ). Thus, the blocking element ( 9 ) is transferred into a blocking position with the aid of the actuator ( 10 ) in which the blocking element ( 9 ) blocks a rotation of the output element ( 7 ) beyond a specified point.

First claim

The invention claimed is:

1. A drive unit for a motor vehicle component, comprising:
an output element having a protrusion,
an electromotor provided for rotating the output element,
an actuator,
a blocking element which is acted on by the actuator and engageable with the protrusion, and
a stop that is fixed to a housing of the drive unit, wherein the blocking element is engageable against the stop when in a resting position in which the stop prevents movement of the blocking element,
wherein the protrusion engages the blocking element to disengage the blocking element from the stop and move the blocking element out of the resting position during a rotational movement of the output element, and
wherein after the blocking element is disengaged from the stop, the blocking element is moved by the actuator into a blocking position in which the blocking element blocks the protrusion and rotation of the output element beyond a specified point.

2. The drive unit of claim 1 , wherein the blocking element situated in the blocking position is transferred by a cessation of force of the output element into a resting position adjacent on the stop.

3. The drive unit of claim 1 , wherein the blocking element is pivotably accommodated in a guide.

4. The drive unit of claim 3 , wherein the guide is integrally formed with the stop.

5. The drive unit of claim 1 , wherein the blocking element has two legs that each have a longitudinal axis that is 90 degree relative to the longitudinal axis of another one of the two legs.

6. The drive unit of claim 5 , wherein one leg of the blocking element is formed at one end as a blocking nose interacting with the stop and at another end as a curved contour interacting with the protrusion.

7. The drive unit of claim 6 , wherein the stop and the blocking nose have forms fitting into one another in a tongue-and-groove connection.

8. The drive unit of claim 7 , wherein another leg of the blocking element is configured as a bearing eye pivotably accommodated in a guide.

9. The drive unit of claim 5 , wherein one of the two legs of the blocking element is configured as a bearing eye pivotably accommodated in a guide.

10. The drive unit of claim 9 , wherein the blocking element is equipped with a pin on which the actuator engages.

11. The drive unit of claim 6 , wherein another leg of the blocking element is configured as a bearing eye pivotably accommodated in a guide.

12. The drive unit of claim 5 , wherein the blocking element is equipped with a pin on which the actuator engages.

13. The drive unit of claim 1 , wherein the blocking element is equipped with a pin on which the actuator engages.

14. The drive unit of claim 13 , wherein the actuator element is formed as a spring.

15. The drive unit of claim 13 , wherein the actuator element is formed as a storage lever sensing a position of a locking mechanism.

16. The drive unit of claim 1 , wherein the actuator element is formed as a spring.

17. The drive unit of claim 1 , wherein the actuator element is formed as a storage lever sensing a position of a locking mechanism.

18. The drive unit of claim 1 , wherein the blocking element and the stop have a tongue-and groove connection therebetween whereby the blocking element is fittingly received within the stop.
