Partial-opening device for a motor-vehicle door element

1. A partial-opening device for a motor-vehicle door element, the partial-opening device comprising:

an electric drive,

an actuating element comprising a pushing element which acts on the door element, and

a gearing arranged between the electric drive and the actuating element,

wherein the actuating element is moved by the electric drive and by the gearing such that the door element is at least partially opened by the actuating element, and

wherein the gearing has a drive lever, and the drive lever is arranged on an outer end of the actuating element that is adjacent to the door element,

wherein the gearing further includes an actuating lever that drives the drive lever, and

wherein in a closed position of the door element the actuating lever engages with the drive lever at a first engagement region, in a partially-open position of the door element the actuating lever engages with the drive lever at both the first engagement region and at a second engagement region, and in an open position of the door element the actuating lever engages with the drive lever at the second engagement region.

2. The partial-opening device according to claim 1 , wherein the drive lever is pivotably fastened to the actuating element.

3. The partial-opening device according to claim 1 , wherein the actuating element has at least one guiding region and one partially opening region.

4. The partial-opening device according to claim 3 , wherein the drive lever is fastened to the actuating element in the partially opening region of the actuating element.

5. The partial-opening device according to claim 3 , wherein at least the partially opening region is formed at least partially from a metallic material.

6. The partial-opening device according to claim 3 , wherein the guiding region comprises two thirds of the actuating element and the partially opening region comprises one third of the actuating element.

7. The partial-opening device according to claim 1 , wherein the actuating element is formed at least partially from plastic.

8. The partial-opening device according to claim 1 , further comprising an adjusting lever, wherein the drive lever is actuated by the adjusting lever.

9. The partial-opening device according to claim 1 , wherein when the door element is in an open position, a bearing point of the drive lever protrudes at least partially from an opening of a car body for the partial-opening device.

10. The partial-opening device according to claim 1 , wherein the actuating element is constructed in at least two parts.

11. The partial-opening device according to claim 1 , wherein when the door element is in an open position, a bearing point of the drive lever protrudes completely from an opening of a car body for the partial-opening device.

12. The partial-opening device according to claim 1 , wherein a ratio of a first radius of rotation of the actuating lever to a second radius of rotation of the drive lever is 1:2.

13. The partial-opening device according to claim 1 , wherein the electric drive engages with the gearing via a Bowden cable.

14. A motor-vehicle door element comprising:

the partial-opening device according to claim 1 ,

an electrically unlockable lock, and

a control unit that operates the partial-opening device to open the electrically unlockable lock.

15. The motor-vehicle door element according to claim 14 , wherein when the door element is in an open position, a bearing point of the drive lever protrudes completely from an opening of the door element for the partial-opening device.
