In this case, the form-locking fastening acts identically except for the operative connection provided for the displacement of the movable roof part between the support rail and the drive slide. To this end, according to the invention, a fastening device is provided that is assigned to the carrier strip. Depending on the travel movement of the drive slide provided for the displacement of the support rail between the closed position, the ventilation position and the open position, the fastening device is displaceable between a fastening position and a release position. In the fastening position, the carrier rail is positively fastened on the drive slide at least in the vertical direction by means of the fastening device. In this case, the form-locking fastening is preferably formed directly between the carrier rail and the drive carriage and/or between the carrier rail and the movable roof part. A firm connection is provided between the member and the drive slider. The form-locking fastening at least in the vertical direction prevents the carrier rail and the roof part fastened thereto in the ready-to-assemble state from being damaged in the vertical direction in the event of a crash. is torn off, and the inner cavity of the motor vehicle is exposed upwards. In the released position, however, the mentioned form-locking fastening is eliminated. As a result, the support rail can be displaced between a closed position, a ventilating position and an open position by means of the travel movement of the drive slide. In the closed position, the movable roof part is closed flush and aligned with the rest of the roof of the motor vehicle. In the ventilation position, the rear region of the movable roof part moves vertically upwards. In the open position, the movable roof part is displaced vertically upwards and longitudinally rearwards, such that the roof opening of the motor vehicle is released. The fastening position of the fastening device is preferably only assumed in the closed position of the movable roof part or of the carrier rail and in the corresponding displacement position of the drive slide on the rail arrangement. middle. During the travel movement of the drive slide for the displacement of the support rail in the direction of the ventilation position and/or the open position, the fastening device is simultaneously displaced into its release position.

The refinement of the invention ensures the fastening of the movable roof part, which can be securely connected to the cover carrier, even in the event of a crash-induced failure of at least one fastening element. For this purpose, the form-locking fastening is formed directly between the cover carrier and the drive slide by means of the fastening device. Preferably, the cover carrier is non-detachably assembled with the movable cover part. For example, the cover carrier can be joined to the underside of the movable cover part by means of surrounding foam or contact foam made of plastic. The carrier strip is assembled with the cover carrier by means of at least one fastening element. The at least one fastening element is preferably configured in the form of a screw for forming a screw connection between the carrier strip and the cover carrier.

This enables a particularly particularly space-saving design of the fastening device. This is because the arrangement on the underside of the drive slide can save structural height in the vertical direction. If the first fastening element is formed by a longitudinally extending recess and/or a longitudinally extending projection of a vertically extending wall section of the cover carrier and/or of the carrier strip, In the event of a crash, the first fastening element engages with the aforementioned wall section of the drive slide at least in the vertical direction in a form-locking manner.

In a further refinement of the invention, the second fastening element is formed by a metal or metal-reinforced wall section of the drive slide. This ensures that the fastening device is subjected to high loads in the event of a crash. As a result, a reliable form-fitting fastening of the cover carrier and/or of the carrier rail in the event of a crash is achieved. Independently of this refinement of the invention, the first fastening element is also preferably formed by a metal or metal-reinforced section of the cover carrier and/or of the carrier profile.

In a further refinement of the invention, the drive slide is produced as a metal-plastic composite component and has a metal insert at least partially encapsulated by plastic injection molding, wherein the second fastening element is the The drive slide is formed by metal inserts or is reinforced by means of the metal inserts. The rail walls extend in a transverse direction. A particularly advantageous design is possible through the production of the drive slide as a metal-plastic composite component and the accompanying configuration of the second fastening element. This is particularly the case with regard to the mechanical loadability of the second fastening element.

Furthermore, the invention relates to a roof system for a motor vehicle with at least one drive system as described above.
