Abstract

A vehicle roof having a roof opening system having a cover element which is displaceable between a closed position, in which a roof opening is closed, and an open position, in which the roof opening is open; displacement kinematics for displacing the cover element on either side of a vertical longitudinal center roof plane, each displacement kinematics may have a guide rail, a first kinematic unit guided in the guide rail, and a second kinematic unit guided in the guide rail; and a set of drive cables for the two kinematic units, the first kinematic unit may have a first deploying lever which is adjustable between a raised position and a lowered position, and the second kinematic unit may have a second deploying lever. The first kinematic unit has a securing slide which is guided in the guide rail and secures the first deploying lever in its lowered position.

First claim

The invention claimed is:

1. A vehicle roof having a roof opening system comprising:
a cover element which is displaceable between a closed position, in which a roof opening is closed, and an open position, in which the roof opening is open;
displacement kinematics for displacing the cover element on either side of a vertical longitudinal center roof plane, each displacement kinematics comprising a guide rail, a first kinematic unit guided in the guide rail, and a second kinematic unit guided in the guide rail; and
a set of drive cables for the two kinematic units, the first kinematic unit comprising a first deploying lever which is adjustable between a raised position and a lowered position, and the second kinematic unit comprising a second deploying lever,
wherein the first kinematic unit comprises a securing slide which is guided in the guide rail and secures the first deploying lever in its lowered position,
wherein the securing slide has a securing protrusion at the front, the securing protrusion interacting with a mating securing element to secure the first deploying lever in its lowered position, the mating securing element being disposed on the first deploying lever or on a component fixed to the cover element, and
wherein the mating securing element has a groove on its underside, the groove engaging a stop element when the cover element is in the closed position, the stop element being disposed on the guide rail and holding the cover element in position in the longitudinal roof direction.

2. The vehicle roof according to claim 1 , wherein the securing slide is a drive slide of the first kinematic unit, the drive slide actuating the first deploying lever.

3. The vehicle roof according to claim 1 , wherein the mating securing element is a securing cam or journal which is disposed on the deploying lever and which extends perpendicular to the guide rail.

4. The vehicle roof according to claim 1 , wherein the set of drive cables comprises a first drive cable, which is driven by a first drive motor and drives the first kinematic unit, and a second drive cable, which is driven by a second drive motor and drives the second kinematic unit.

5. The vehicle roof according to claim 1 , wherein a sliding element is disposed on the second deploying lever, a guide track of a cover support of the cover element being guided on the sliding element when the cover element is being displaced.
