## Abstract

A drive device for a pivotable vehicle flap includes a flap part associated with the vehicle flap, a body part associated with a vehicle body and a hinge arrangement which hingedly connects the flap part and the body part, the hinge arrangement allowing the flap part to be pivoted about a first axis of rotation for opening and closing the vehicle flap and about a second axis of rotation for raising the vehicle flap into a pedestrian protection position. The device drive also includes a first actuator for opening and closing the vehicle flap during normal operation, a second actuator for raising the vehicle flap into a pedestrian protection position and a coupling device for coupling the first actuator to one of the flap part and the vehicle flap. The coupling device includes a fastening part and a first coupling element coupled to the first actuator.

## Claims

### Claim 1

A drive device for a pivotable vehicle flap comprising:
a flap part associated with the vehicle flap;
a body part associated with a vehicle body;
a hinge arrangement which hingedly connects the flap part and the body part, the hinge arrangement allowing the flap part to be pivoted about a first axis of rotation for opening and closing the vehicle flap and about a second axis of rotation for raising the vehicle flap into a pedestrian protection position;
a first actuator for opening and closing the vehicle flap during normal operation;
a second actuator for raising the vehicle flap into the pedestrian protection position; and
a coupling device for coupling the first actuator to one of the flap part and the vehicle flap, comprising a fastening part which is fixedly connected to the one of the flap part and the vehicle flap and a first coupling element coupled to the first actuator, wherein the first coupling element is moveable from a locking position to a release position by moving in a translational manner relative to the fastening part, wherein it is possible for the first coupling element to rotate about a third axis of rotation relative to the fastening part in the release position.

### Claim 2 (depends on 1)

The drive device according to claim 1, wherein the fastening part comprises a holding device which locks the first coupling element in the locking position in a rotationally fixed manner relative to the fastening part.

### Claim 3 (depends on 2)

The drive device according to claim 2, wherein the holding device comprises at least a first holding element and a second holding element, which engage around the first coupling element in the locking position.

### Claim 4 (depends on 1)

The drive device according to claim 1, wherein a mechanical securing element secures the first coupling element in the locking position against moving in a translational manner relative to the fastening part.

### Claim 5 (depends on 4)

The drive device according to claim 4, wherein the mechanical securing element is released when the second actuator is actuated, by breaking a predetermined breaking point, so that the first coupling element can move in a translation manner relative to the fastening part.

### Claim 6 (depends on 1)

The drive device according to claim 1, wherein the first coupling element has an inner recess for guiding the first coupling element relative to the fastening part.

### Claim 7 (depends on 6)

The drive device according to claim 6, wherein the inner recess extends longitudinally so that the first coupling element is guided at least in a first portion of its translational movement.

### Claim 8 (depends on 6)

The drive device according to claim 6, wherein the inner recess is an elongated hole.

### Claim 9 (depends on 6)

The drive device according to claim 6, wherein a bearing element which is fixedly arranged on the fastening part passes through the inner recess.

### Claim 10 (depends on 9)

The drive device according to claim 9, wherein the bearing element is arranged in the locking position at a first end of the inner recess and, in the locking position, is arranged at a second end of the inner recess opposite the first end.

### Claim 11 (depends on 10)

The drive device according to claim 10, wherein the third axis of rotation is formed by the bearing element.

### Claim 12 (depends on 9)

The drive device according to claim 9, wherein the third axis of rotation is formed by the bearing element.
