Abstract

Adjusting device for a front lid, with an actuator for raising the rear edge of the front lid, wherein the actuator is configured as a coupling mechanism having a first drive with a rotation-locked lever connected to a push rod in an articulated fashion and a second drive with a rotation-locked lever connected to a push rod in an articulated fashion, wherein the two push rods have a common attachment point, via which they are connected to the front lid.

First claim

What is claimed is:

1. An adjusting device for a front lid, with an actuator for raising a rear edge of the front lid, the actuator comprising:
a coupling mechanism comprising a first drive having a rotation-locked lever connected to a first push rod in an articulated fashion and a second drive having a rotation-locked lever connected to a second push rod in an articulated fashion, wherein the first and second push rods are connected with one another at a common attachment point which is in turn connected to the front lid.

2. The adjusting device of claim 1 , wherein the first and the second drive comprise an electric motor.

3. The adjusting device of claim 2 , wherein the electric motor comprises a reduction gear.

4. The adjusting device of claim 1 , further comprising a leg attached to the front lid, wherein the common attachment point of the first and second push rods is connected to the leg.

5. The adjusting device of claim 4 , wherein the leg is constructed as a U-shaped profile.

6. The adjusting device of claim 1 , further comprising a control device configured to control the first and the second drive in a coordinated fashion.

7. The adjusting device of claim 6 , wherein the control device is configured to control the first and the second drive so as to move the front lid to a raised and horizontally rearward displaced pedestrian protection position or to an even further raised and even further horizontally rearward displaced type damage position.

8. The adjusting device of claim 6 , wherein the control device is configured to control the first and the second drive so as to move the front lid to a service position where the rear end of the front lid is supported in an abutment that is fixed in relation to the vehicle body.

9. A motor vehicle comprising at least one adjusting device for a front lid, with an actuator for raising a rear edge of the front lid, the actuator comprising:
a coupling mechanism comprising a first drive having a rotation-locked lever connected to a first push rod in an articulated fashion and a second drive having a rotation-locked lever connected to a second push rod in an articulated fashion, wherein the first and second push rods are connected with one another at a common attachment point which is in turn connected to the front lid.

10. The motor vehicle of claim 9 , comprising two adjusting devices arranged at opposite sides of an engine compartment.
