Openable motor vehicle roof with improved sliding head liner guide arrangement

Openable motor vehicle roof, comprising:

• at least one cover which can close a roof opening and which can be raised out of a cover closed position into a cover raised position;
• a sliding head liner located under the at least one cover and moveable concomitantly out of a closed position into a raised position when the at least one cover is raised with the sliding headliner, so that the at least one cover and the sliding head liner jointly clear a ventilation gap, the sliding head liner being slideable furthermore from its closed position into an open position so that the sliding head liner can clear the cover or the roof opening at least for a large part;
• an elongated guide element along which the sliding head liner can be moved into and out of its open position and including a movable end on which the sliding head liner is held in its closed position and, in the liner raised position, is entrained during motion of the sliding head liner between the closed and raised positions, the elongated guide element including a stationary area and a transition area between the stationary area and the movable end;
• a movable holding device mounted on the elongated guide element to hold the sliding head liner on a side on which the sliding head liner can clear the ventilation gap in the raised position of the sliding head liner;
• wherein the sliding head liner is pushed in the stationary area away from the movable end through which or into which the holding device is pushed during motion into the open position of the sliding head liner, in the direction perpendicular to the roof to hold the sliding head liner stationary with respect to the roof, the guide element being flexible at least in the transition area between the stationary area and the movable end.
