Sunshade device for a transparent vehicle part and vehicle roof with a sunshade device

The sun shield has an extractable visor part (5), which can be moved towards a front or rear edge (9,13) of e.g. a roof opening. The visor part can be moved in longitudinal direction of the vehicle while in original or partially extracted positions. The part is mounted on a cross strut (7), which can be moved in longitudinal vehicle direction. A second extractable visor part (11) is provided for a part of the roof opening, which is not covered by the first part. There is a drive for one or both visor parts and/or the strut.
