Actuating device for a parking brake of a motor vehicle

Abstract

The invention relates to an actuating device for a parking brake of a motor vehicle, with at least one lever which is operatively connected to the parking brake via traction means and which is mounted such that it can pivot between a rest position and a brake application position about a first pivot axis which is positionally fixed with respect to the vehicle body. A rod is coupled to the lever such that it can pivot about a second pivot axis which is moveable with respect to the vehicle body and is parallel to the first pivot axis, the rod bearing a handle element and being mounted on the vehicle body such that it can pivot about a third pivot axis, which is positionally fixed with respect to the vehicle body, and such that it can be displaced along its longitudinal direction.

Claims

1. An actuating device for a parking brake of a motor vehicle, the motor vehicle having a vehicle body, the device comprises: at least one lever operatively connected to the parking brake, the at least one lever having a rest position and a brake application position, anda rod coupled to the at least one lever, the rod having a handle element;wherein the at least one lever is arranged such that the at least one lever can pivot between the rest position and the brake application position about a first pivot axis which is positionally fixed with respect to the vehicle body; the rod coupled to the at least one lever can pivot about a second pivot axis, the second pivot axis being moveable with respect to the vehicle body and substantially parallel to the first pivot axis; andthe rod is arranged on the vehicle body such that it can pivot about a third pivot axis which is positionally fixed with respect to the vehicle body such that it can be displaced along its longitudinal direction.

2. The actuating device as claimed in claim 1, further comprising a second rod wherein the respective first and second rods are coupled such that they can pivot about the second pivot axis.

3. The actuating device as claimed in claim 2, wherein the first and the second rod are connected rigidly to each other in an arrangement parallel to each other.

4. The actuating device as claimed in claim 3, wherein the first and the second rod are connected rigidly to each other in an arrangement parallel to each other via the handle element.

5. The actuating device as claimed in claim 1, wherein the rod is case mounted in a sliding bearing which is coupled to the vehicle body.

6. The actuating device as claimed in claim 5, wherein the sliding bearing is coupled pivotably to a support arm which is positionally fixed with respect to the vehicle body and extends essentially into the region of the first pivot axis.

7. The actuating device as claimed in claim 2, wherein the first and the second lever are connected rigidly to each other in an arrangement parallel to each other.

8. The actuating device as claimed in claim 1, wherein the rod is mounted on the lever and on the vehicle body in such a manner that the angle between the rod and the lever coupled thereto is not more than 90° over the entire pivoting travel of the lever from the rest position to the brake application position.

9. The actuating device as claimed in claim 1, wherein the handle element moves only in one direction over the entire pivoting travel of the lever from the rest position to the brake application position.

10. The actuating device as claimed in claim 1, wherein the handle element moves only in preferably in the driving direction.
