Abstract: A power operating system for opening and closing a vehicle liftgate (12) has a pair of drive units (22, 22') supported on the vehicle roof and connected to the liftgate (12) for opening and closing the liftgate (12). Each drive unit (22, 22') includes a housing (38, 60) having a curved track (80) and a curved gear rack (48) that is bodily movable endwise in the housing (38, 60) and guided by the curved track (80), the rack (48) also serving as the drive link between the housing (38, 60) and the liftgate (12). The combined rack and drive link is extended and retracted by a pinion gear (40) that is journalled interiorly in the housing and engages the teeth of the curved gear rack (48). The pinion gear (40) is rotated by the output shaft (62) of the motor (24), which in turn is fastened to the side of the housing (38, 60). The motor (24) is a reversible electric motor and is adapted to be operably coupled to the vehicle ECU unit and preferably includes an internal transmission and electrically operated clutch controlled by the ECU unit.
