Two roof elements (10,12) within a roof opening are adjustable between open and closed positions. When in closed position, the two elements engage into each other like a tongue-and-groove connection (14), for relative sealing. The connection consists of partially wedge-shaped tongues (16,18) and corresponding grooves (20,22). At least one of the springs and one of the grooves has an associated seal. One of the roof elements is at least partially transparent, and is of glass or plastic. |
