Abstract

The invention relates to a motor vehicle door handle for locking and/or activating a door of a motor vehicle, having a handle housing and a pulling handle arranged in the handle housing, wherein in a closed position the pulling handle terminates flush with the handle housing and/or rests in the handle housing and can be moved into an operating position in which the pulling handle protrudes outward from the handle housing and it can be gripped from the rear, wherein when the pulling handle is pulled manually in the operating position the door lock and/or the door opens, wherein the pulling handle has two articulation points spaced apart from one another, wherein the pulling handle is mounted at the first articulation point in an articulated fashion at one end of a first rotary lever, and is mounted spaced apart therefrom at the second articulation point in an articulated fashion at one end of a second rotary lever, wherein the two rotary levers rotate about rotational axes in order to move the pulling handle from the closed position into the operating position.

First claim

The invention claimed is:

1. A motor vehicle door handle for actuating a door lock and/or a door of a motor vehicle, comprising a handle housing and a pulling handle arranged in the handle housing,
wherein in a closed position the pulling handle terminates flush with the handle housing and/or rests in the handle housing and can be displaced into an operating position, in which the pulling handle protrudes outwardly from the handle housing and can be gripped from the rear,
wherein when the pulling handle is pulled manually in the operating position the door lock and/or the door opens,
wherein the pulling handle comprises two articulation points spaced apart from each other,
wherein the pulling handle is supported on the first articulation point in an articulated fashion at one end of a first rotary lever and is supported spaced apart therefrom at the second articulation point in an articulated fashion at one end of a second rotary lever,
wherein the two rotary levers rotate about rotational axes, to displace the pulling handle from the closed position to the operating position,
wherein the motor vehicle door handle comprises a locking element, which is indirectly or directly kinematically coupled to the pulling handle and which is engaged in the closed position of the pulling handle and locks the pulling handle, wherein the locking element is displaced into a release position by means of an actuation lever before the actuation lever acts on one of the two rotary levers and pivots said lever about its rotational axis,
wherein the motor vehicle door handle comprises an electric motor drive acting on the actuation lever.

2. The motor vehicle door handle according to claim 1 , wherein the rotational axes run parallel to one another at a distance.

3. Motor vehicle door handle according to claim 1 , wherein the articulation points are arranged successively in an extension direction of the pulling handle.

4. Motor vehicle door handle according to claim 1 , wherein the rotational axes, around which the rotary levers are rotated when the pulling handle is displaced, are arranged successively in the extension direction of the pulling handle.

5. The motor vehicle door handle according to claim 1 , wherein the distance of the two articulation points of the pulling handle and the distance of the rotational axes of the two rotary levers is generally equal, so that the articulation points and the rotational axes of the two rotary levers form corner points of a parallelogram.

6. The motor vehicle door handle according to claim 1 , wherein the actuation lever, which acts on one of the two rotary levers and pivots said lever around its rotational axis, is configured to cause the displacement of the pulling handle from the closed position into the operating position.

7. The motor vehicle door handle according to claim 1 , wherein the locking element is formed by a cam, which is arranged at a front end of a pivot lever coupled to the actuation lever and which displaceable from a latching position into a release position in a link on the handle housing.

8. Motor vehicle door handle according to claim 1 , wherein the motor vehicle door handle comprises at least one spring element which exerts a spring force on at least one of the two rotary levers effective in the direction of the closed position.

9. The motor vehicle door handle according to claim 1 , wherein the motor vehicle door handle comprises an actuation member which directly or indirectly acts on one of the two rotary levers and which pivots said lever around its rotational axis upon manual actuation of the actuating element and displaces the pulling handle into the operating position.
