A folding top compartment lid, in particular a folding top compartment lid with an integrated engine bay lid, is pivoted into an open position and into a closed position by a so-called four-bar hinge arrangement. An actuating device is articulatedly connected to a rear and a front setting-out lever of the four-bar hinge mechanism, which actuating device is coupled to a locking device which contains locking hooks. The actuating device with the setting-out levers can be activated by a hydraulic cylinder so as to pivot into the open and closed positions in such a way that the folding top compartment lid can be moved from the locked closed position into an unlocked open position and back from the open position into the closed position.
