  • Patent number: 4786102
    Abstract: A vehicle roof having a fixed roof structure through which a roof opening extends and which is closable and selectively openable by a sunroof apparatus having a pair of cover panels which, in a position closing the roof opening, are disposed one behind the other in the vehicle longitudinal direction. The front panel is displaceable from its closed position into an upwardly tilted position and, while upwardly tilted, is rearwardly slidable to a position in which a rear portion of the front cover panel projects over the rear cover panel or, when the rear cover panel (which is detachably mounted) is removed, projects over a rear edge of the roof opening. The construction of the sunroof apparatus enables the roof opening to extend approximately the full length of the fixed roof structure.
