Actuating device for the folding roof of a motor vehicle

Abstract

An actuating device for opening and closing a folding roof (2) of a motor vehicle with a bearing carriage (3) which is movably supported on a roof-side guideway (4) and which is connected to the movable part (7) of the folding roof (2), and with a drive means which is connected to the bearing carriage (3) by a drive carriage (10) which is supported on the roof-side guideway (11) and a connecting rod arrangement (13, 14) which has a toggle lever (14) and which is controlled by a control guideway (23), on the last portion of the closing path, the connecting rod arrangement (13, 14) steps down the drive motion of the drive carriage (10). To improve the behavior of the actuating device in the closed state, it is provided that the toggle lever (14) of the connecting rod arrangement which is pivotally connected to the pivot arm (15) of the bearing carriage (3) can be moved along the control guideway (23) into a closed position in which it exhibits a self-locking behavior with respect to opening forces which act on the bearing carriage (3) via the roof part (7).
