ROOF SYSTEM

A roof system comprises a stationary part configured for a roof opening from above. A panel is configured to close the roof opening and open the roof opening. The stationary part includes a frame extending along at least a substantial part of a circumference of the roof opening and being attached to the fixed roof of the vehicle. Guide rails extend in longitudinal direction substantially parallel to opposite sides of the roof opening and substantially within the longitudinal length of the roof opening. The guide rails are slidably supporting an operating mechanism for the panel and are attached to the frame. The guide rails extend at least partly below the frame, at least in points of attachment where the guide rails are attached on their outer sides to the frame. The points of attachment are positioned below an area adjacent the longitudinal sides of the panel, when in closed position.
