Abstract
A vehicle pivoting closure assembly has a concealed power actuator remotely operated by a controller to open and close a closure or liftgate. A hinge member of the power actuator is engaged pivotally to a vehicle structure about a hinge axis, and rigidly to the closure. An armature extends pivotally from an elongated linear moving rack about a rack pivot axis and to the hinge member. The armature also pivotally engages the hinge member about a secondary pivot axis disposed parallel to the hinge axis and rack pivot axis. The rack is driven by a pinion gear train powered by a motor through a clutch. The hinge, the rack, the gear train and the motor are all supported by a reinforcement tray forming a modular engaged to the vehicle structure. The tray isolates the extreme dynamic loads placed upon the hinge by the motor, thereby eliminating the need to further reinforce the vehicle structure.
