Abstract: The present invention is concerned with a double door drive unit with spring closing system wherein the double door is opened by means of a drive unit and closed by spring force. It is characterized in that a toothed rack is guided axially movable on a rotating driven ball screw, said toothed rack operating against the load of a spring actuator, and that the toothed rack is in combing engagement with a pinion, which, in turn is connected to the driving linkage for the double door drive unit in such a way that it is integral in rotation with said driving linkage. This results in a very space-saving design for the device.
