## 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

### Claim 1

An actuating device for parking brake of a motor vehicle, the motor vehicle having a vehicle body, the device comprises:
a lever operatively connected to the parking brake, the lever being pivotable between a rest position and a brake application position about a first pivot axis which is positionally fixed with respect to the vehicle body; and
a rod coupled to the lever, the rod being pivotable about:
a second pivot axis which is movable with respect to the vehicle body and substantially parallel to the first pivot axis; and
a third pivot axis which is positionally fixed with respect to the vehicle body, such that the rod can be displaced along its longitudinal direction, wherein, the longitudinal direction is parallel to a plane constituted by the second and the third pivot axis; and
a handle element directly attached to the rod;
wherein the rod is mounted on the lever and on the vehicle body such 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.

### Claim 2 (depends on 1)

The actuating device of claim 1, further comprising a second rod, wherein the first rod and the second rod are coupled such that they can pivot about the second pivot axis.

### Claim 3 (depends on 2)

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

### Claim 4 (depends on 3)

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

### Claim 5 (depends on 1)

The actuating device of claim 1, wherein the rod is longitudinally movable in a sliding bearing which is coupled to the vehicle body.

### Claim 6 (depends on 5)

The actuating device of 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 into the region of the first pivot axis.

### Claim 7 (depends on 1)

The actuating device of claim 1, wherein the handle element moves in a substantially circular arc over the entire pivoting travel of the lever from the rest position to the brake application position.

### Claim 8

An actuating device for parking brake of a motor vehicle, the motor vehicle having a vehicle body, the device comprising:
a lever operatively connected to the parking brake, the lever being pivotable between a rest position and a brake application position about a first pivot axis which is positionally fixed with respect to the vehicle body; and
a rod, coupled to the lever and movable through a sliding bearing coupled to the vehicle body, wherein the rod is pivotable about:
a second pivot axis which is movable with respect to the vehicle body and substantially parallel to the first pivot axis; and
a third pivot axis which is positionally fixed with respect to the vehicle body such that the rod can be displaced along its longitudinal direction, longitudinal direction is parallel to a plane constituted by the second and the third pivot axis; and
a handle element directly attached to the rod;
wherein the rod is mounted on the lever and on the vehicle body such 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.

### Claim 9 (depends on 8)

The actuating device of claim 8, wherein the sliding bearing is coupled pivotably to a support arm which is positionally fixed with respect to the vehicle body and extends into the region of the first pivot axis.
