Abstract (en)

[origin: WO0227133A1] A liftgate force control assembly (20) adjusts the force required to move a liftgate (12) that is pivotally secured to a motor vehicle (10) using a hinge (14). The liftgate force control assembly includes a track (42) that is fixedly secured to the motor vehicle. A follower (46) is movably secured to the track. A strut (34, 36) has a movable end (26, 28) and a secured end (30, 32). The secured end (30, 32) is pivotally secured to the liftgate (12) and the movable end (26, 28) is pivotally secured to the follower (46). The strut (34, 36) defines a moment with respect to the hinge that secures the liftgate to the motor vehicle. A motor (50) is connected to the follower (46) to move the follower (46) along the track (42) changing the moment of the strut such that the force required to move the liftgate (12) changes as the moment changes.
