Abstract

Claims (26)

1 . A setting-open device for a motor vehicle door including a door leaf, the setting-open device comprising:

an electric-motor drive,

a lever mechanism including a short lever and a long lever, and

an actuating element,

wherein the actuating element is configured to act on the door leaf,

wherein the actuating element acts on the door leaf with a travel-dependent force along an actuation travel of the actuating element,

wherein the electric-motor drive acts on the actuating element by interposition of the lever mechanism,

wherein the lever mechanism acts on the actuating element by way of at least the short lever and the long lever,

wherein the electric-motor drive includes an electric motor and a gear wheel rotated by the electric motor, wherein the gear wheel includes an axle,

wherein the short lever and the long lever are mounted on the axle of the gear wheel of the electric-motor drive, and

wherein the actuating element is designed as a one piece rigid linearly movable actuating slide, and the short lever and the long lever directly engage and act on the linearly movable actuating slide.

2 . The setting-open device according to claim 1 , wherein the actuating element includes an end pin, and

wherein the short lever directly acts on the end pin of the actuating element.

3 . The setting-open device according to claim 1 , wherein the actuating element includes a cantilever, and

wherein the long lever directly interacts with the cantilever of the actuating element.

4 . The setting-open device according to claim 1 , wherein the short lever and the long lever directly act on the actuating element successively.

5 . The setting-open device according to claim 4 , wherein starting from an end position, the actuating element is configured to be first directly acted on by the short lever and then by the long lever.

6 . The setting-open device according to claim 1 , wherein the short lever and the long lever form an angular distance, and

wherein the angular distance is 20° to 40°.

7 . The setting-open device according to claim 1 , wherein the short lever includes a first stop edge and the long lever includes a second edge, and

wherein the linearly movable actuating slide is equipped with a first stop contour configured to directly interact with the first stop edge and a second stop contour configured to directly interact with the second stop edge.

8 . The setting-open device according to claim 7 , wherein the first and second stop contours are spaced apart such that the first stop edge of the short lever directly acts on the first stop contour before the second stop edge of the long lever directly acts on the second stop contour.

9 . The setting-open device according to claim 1 , wherein the gear wheel is part of a reduction gear mechanism.

10 . The setting-open device according to claim 1 , wherein at least one of the actuating element, the short lever, and the long lever is plastic.

11 . The setting-open device according to claim 1 , further comprising a housing including a linear guide configured to support the linearly movable actuating slide.

12 . The setting-open device according to claim 11 , wherein the housing is sealed.
