Sliding roof system

1. A sliding roof system comprising:

a frame;

a cover that is movable between a closed position, a ventilation position, and an open position;

a lateral safety screen that is positionable in a covering position to extend to lie to a side of and underneath the cover, wherein the lateral safety screen is attached to the frame, and wherein the lateral safety screen is shiftable between a lowered position, the covering position which is taken by the lateral safety screen when the cover is in the ventilation position, and a release position that the lateral safety screen takes when the cover is in the open position; and

a wind deflector that is shiftable between a lowered position and a lifted position wherein the lateral safety screen is coupled with the wind deflector by a slotted piece guide.

2. The sliding roof system according to claim 1 wherein the slotted piece guide comprises a guide pin on the wind deflector and a guiding slot on the lateral safety screen.

3. The sliding roof system according to claim 1 wherein the wind deflector is biased into the lifted position by a wind deflector spring.

4. The sliding roof system according to claim 1 wherein at an end of the lateral safety screen that faces away from the wind deflector, the lateral safety screen includes a stop that can come into contact with the cover.

5. The sliding roof system according to claim 4 wherein a raising spring biases the end of the lateral safety screen that includes the stop, towards the cover.

6. A sliding roof system comprising:

a frame;

a cover that is movable between a closed position, a ventilation position and an open position;

a lateral safety screen that is positionable in a covering position to extend to lie to a side of and underneath the cover wherein the lateral safety screen is attached to the frame, and wherein the lateral safety screen is shiftable between a lowered position the covering position which is taken by the lateral safety screen when the cover is in the ventilation position, and a release position that the lateral safety screen takes when the cover is in the open position;

a wind deflector that is shiftable between a lowered position and a lifted position wherein at an end of the lateral safety screen that faces away from the wind deflector, the lateral safety screen includes a stop that can come into contact with the cover; and

a raising spring that biases the end of the lateral safety screen that includes the stop, towards the cover, wherein the raising spring acts on a raising lever that is coupled with the lateral safety screen.

7. The sliding roof system according to claim 5 wherein the raising spring is a leg spring.

8. The sliding roof system according to claim 6 wherein the raising lever is pivotally mounted to a guide rail.

9. The sliding roof system according to claim 1 wherein at an end of the lateral safety screen that faces away from the wind deflector, the lateral safety screen includes a stop that can come into contact with the cover, and wherein between the slotted piece guide and the stop is an abutment that couples the lateral safety screen with a guide rail.

10. The sliding roof system according to claim 9 wherein the abutment pivotally receives the lateral safety screen such that the lateral safety screen is able to move to a limited extent.

11. The sliding roof system according to claim 9 wherein the abutment is formed by an abutment stud on the lateral safety screen and an elongated hole on the guide rail.
