Abstract

A handle device for a motor vehicle door includes a door handle, which is hinged at both ends to an electrically driven movement kinematic system. A first end of the door handle is rotatable outwards via a motor-operated pivot lever. A push rod is hinged to the pivot lever, the other end of which is hinged to a locking lever, which acts on a toggle lever pair. One end of a first toggle lever is mounted on the housing side and one end of a second toggle lever is hinged to a second end of the door handle. The locking lever is designed, in a standby position, to block a movement of the door handle back into a rest position and to permit a movement into an opening position.

Claims (25)

1. A handle device for a motor vehicle door, the handle device comprising:

an electrically driven movement kinematic system, which comprises a motor-operated pivot lever and a push rod, wherein a first end of the push rod is hinged to the motor-operated pivot lever; and

a door handle, which is hinged at first and second ends to the electrically driven movement kinematic system such that the door handle is moveable from a retracted rest position into an extended standby position and back, wherein in the extended standby position, a compressive force acting on the door handle from outside is transferrable to the motor vehicle door, and the door handle is moveable into an opening position by a tensile force;

wherein the first end of the door handle is rotatable outwards by the motor-operated pivot lever, a second end of the push rod is hinged to a locking lever acting on the door handle,

wherein a first end of a first toggle lever and a first end of a second toggle lever are hingedly connected to each other by a toggle hinge, a second end of the first toggle lever is hinged to a rear hinge point of the second end of the door handle, and a second, free end of the second toggle lever is mounted on the housing side and has a rotation axis on the housing side,

wherein the locking lever is configured to block a movement of the door handle back into the retracted rest position in the extended standby position, and to permit a movement into the opening position.

2. The handle device of claim 1 , wherein the first end of the door handle is a front end of the door handle in a direction of the vehicle.

3. The handle device of claim 1 , wherein the motor-operated pivot lever is rotatable about an axis of rotation fixed to the housing by a cam disc actuated by a drive motor.

4. The handle device of claim 1 , wherein the locking lever has a locking tab which is rotatable during a movement from the retracted rest position to the extended standby position, wherein the locking tab abuts the first toggle lever in a sliding manner.

5. The handle device of claim 4 , wherein, in the extended standby position, the locking tab is aligned in a direction of force action of the compressive force acting at a hinge point of the door handle on the first toggle lever.

6. The handle device of claim 1 , wherein the hinge points of the push rod on the motor-operated pivot lever and on the locking lever are selected in such a way that a rotary movement of the motor-operated pivot lever leads to an outward synchronous movement of the door handle at both ends of the door handle.

7. The handle device of claim 1 , wherein when the door handle is moved from the extended standby position into the opening position, a pivot lever-sided hinge point of the door handle remains stationary and the second end of the door handle is rotatable about the pivot level-sided hinge point.

8. A motor vehicle door, comprising:

a handle device, comprising

an electrically driven movement kinematic system, which comprises a motor-operated pivot lever and a push rod, wherein a first end of the push rod is hinged to the motor-operated pivot lever; and

a door handle, which is hinged at first and second ends to the electrically driven movement kinematic system such that the door handle is moveable from a retracted rest position into an extended standby position and back, wherein in the extended standby position, a compressive force acting on the door handle from outside is transferrable to the motor vehicle door, and the door handle is moveable into an opening position by a tensile force;

wherein the first end of the door handle is rotatable outwards by the motor-operated pivot lever, a second end of the push rod is hinged to a locking lever acting on the door handle,

wherein a first end of a first toggle lever and a first end of a second toggle lever are hingedly connected to each other by a toggle hinge, a second end of the first toggle lever is hinged to a rear hinge point of the second end of the door handle, and a second, free end of the second toggle lever is mounted on the housing side and has a rotation axis on the housing side,

wherein the locking lever is configured to block a movement of the door handle back into the retracted rest position in the extended standby position, and to permit a movement into the opening position.

9. The motor vehicle door of claim 8 , wherein the first end of the door handle is a front end of the door handle in a direction of the vehicle.

10. The motor vehicle door of claim 8 , wherein the motor-operated pivot lever is rotatable about an axis of rotation fixed to the housing by a cam disc actuated by a drive motor.

11. The motor vehicle door of claim 8 , wherein the locking lever has a locking tab which is rotatable during a movement from the retracted rest position to the extended standby position, wherein the locking tab abuts the first toggle lever in a sliding manner.

12. The motor vehicle door of claim 11 , wherein, in the extended standby position, the locking tab is aligned in a direction of force action of the compressive force acting at a hinge point of the door handle on the first toggle lever.

13. The motor vehicle door of claim 8 , wherein the hinge points of the push rod on the motor-operated pivot lever and on the locking lever are selected in such a way that a rotary movement of the motor-operated pivot lever leads to an outward synchronous movement of the door handle at both ends of the door handle.

14. The motor vehicle door of claim 8 , wherein when the door handle is moved from the extended standby position into the opening position, a pivot lever-sided hinge point of the door handle remains stationary and the second end of the door handle is rotatable about the pivot level-sided hinge point.
