Vehicle roof with a movable closing element

The adjustable sliding roof has a front part, behind which there is a rear part (14). The front part runs along a fixed guide rail to pass under the rear part. A side membrane (70) is fitted below the rear part and behind the gutter (122), both sides, and taken into the guide fixed to the roof. It moves back with the front part of the sliding roof and protects the system against possible jamming by foreign bodies etc.
