Abstract: An apparatus for opening and closing a deck lid of a vehicle body includes a jack-screw type drive unit having two elongated relatively rotatable drive elements which are threadably engaged for bi-directional displacement. An electric motor engages the rotatable drive element. A first mounting device pivotally connects the rotatable drive element to a relatively fixed point on the vehicle. A second mounting device pivotally connects the non-rotatable drive element to the deck lid, or vice versa. The motor is energized to affect bi-directional control of the drive unit while enabling low back-drive effort. A concentric spring counters loading due to the weight of the deck lid.

Abstract: The present invention provides a drive mechanism for a vehicle lift gate. The drive mechanism includes a housing including a first end securable to a vehicle frame and an opposite second end securable to a lift gate. The drive mechanism further includes a spring disposed for movement within the housing along the axis between the first and second ends and biasing the first end axially relative to the second end. A damper extends around the housing for absorbing energy released by rapid axial movement of the spring relative to the housing.
