ABSTRACT:
The invention relates to an opening and closing device for a vehicle roof hatch (1). The device according to the invention comprises a stationary bar (4) and a toggle lever system connected to both ends of the bar. One end of the long lever arm (5) of the lever system is connected movably to the bar (4) and its other end of the roof hatch (1). One end of the shorter lever arm (6), which is half the length of the longer lever, is connected stationarily to the bar and its other end to the middle (7) of the long lever arm. The bar is threaded so that one half is threaded in one direction and the other half in the opposite direction. The bar is driven by an electric motor, whereupon the toggle lever system "opens" or "closes", depending on the direction of rotation, and raises or respectively lowers the roof hatch side in question, maintaining the side horizontal at all times.
