SLIDING DOOR SYSTEM FOR A VEHICLE

The invention relates to a sliding door system (1) for a motor vehicle, comprising a frame with a door opening in a side wall of the motor vehicle, a door opening in the frame, and a sliding door (2) and a second door (T) for closing off the door opening, wherein no body column is arranged between the sliding door (2) and the door (T). In order to open and close the door opening, the sliding door (2) can be moved, by means of a guide device (3) with guide rails (5,6,7), along a path, which is non-linear relative to the vehicle body, in a closing direction (s) from an open position into a closed position, and said sliding door (2) can be fixed in the closed position by means of a closing device. In order to simplify the sliding door system, it is proposed that a rear guide rail with respect to the closing direction, in which the sliding door is movably mounted with a rear end region with respect to the closing direction, has an S-shaped profile with a rear end section with respect to the closing direction which is arranged approximately parallel to the larger side face of the sliding door in the closed position, and that the closing device comprises a closing mechanism, by means of which the front end region of the sliding door with respect to the closing direction can be detachably fastened to the longitudinal frame.
