  • Publication number: 20060181108
    Abstract: A power-operated system for actuating the rear doors or liftgates of motor vehicles is disclosed. The system includes an articulating strut mounted between a vehicle frame and the rear door. A motor assembly is operatively coupled between the articulating strut and the vehicle frame for changing the angular orientation and, in turn, mechanical advantage provided by the articulating strut. The articulating strut is moved into angular orientations of greater mechanical advantage in order to effect opening of the rear door and lesser mechanical advantage to effect closing of the rear door.

  • Patent number: 7070226
    Abstract: A power-operated system for actuating the liftgates of motor vehicles is disclosed. The system includes a controllable strut with internal locking structure that includes a driver and a valve assembly. The controllable strut is typically mounted on one side of the liftgate between the liftgate and the vehicle's frame. Conventional strut may be mounted on the other side of the liftgate. One end of each strut is connected to a powered articulating arm. To move the liftgate between open and closed positions, the articulating arms move the controllable strut and the other strut between positions of greater and lesser mechanical advantage. During the movements, the locking structure in the controllable strut may be activated and deactivated either cyclically or continuously to momentarily to retain the controllable strut as particular lengths.
