Foldable hardtop for vehicle

The roof has a rear window (7) pivotably mounted with respect to a rear upper edge of a rear trunk (6) so that the window is lowered when front and rear semi-roofs (4, 5) cover a cab interior. An upper part of the trunk is completely covered by the roofs. Two rear side panels (13) are vertically situated on both sides of the window. Each panel is raised and lowered in the trunk, when the roof is deployed and retracted, respectively.
