Abstract: Control apparatus is provided for an electromechanically operated closure panel such as used for sun roofs of automobiles and the like. The control apparatus includes a reversible electric motor drivingly connected to move the closure panel between a closed position and respective slidably retracted and pivoted open positions. In order to accommodate for the differences in relative movement between the electric motor and the closure panel during movement between the closed position and the tilted position, as compared to the movement between the closed position and the slidably retracted position, the invention provides a control mechanism for controlling the speed of the electric motor so as to reduce the same during tilting movement of the closure panel.

Abstract: A control device for a motor-driven closure panel, for instance an automobile sunroof panel whose closed position is an intermediate position between an open, retracted position and another open, pivoted position, the circuitry for the reversible motor including an impulse relay operating a control switch in one of the two motor connections, the relay coil being connected in parallel to the motor and between the control switch and the pole reversing switch, a position-responsive switch cutting off the relay circuit whenever the panel moves out of its closed position and energizing the impulse relay whenever the panel reaches the closed position. An improved switch arrangement prevents the panel from being stuck in a position in which the reversible motor becomes inoperative.
