Abstract: A closure is supported on a vehicle body for generally vertical bodily shiftable movement between open and closed positions relative to an opening in the vehicle body by a hinge arm supported on the vehicle body for pivotal movement about a first axis of the latter. The weight of the closure produces on the hinge arm about the first axis a gravitational turning moment which is counterbalanced by a hinge counterbalance according to this invention including a torsion rod with a crank thereon, an intermediate lever pivotally supported on the vehicle body, a connecting link between the torsion rod and the intermediate lever, cam means on the intermediate lever and follower means on the hinge arm. The torsion rod through the connecting link produces a primary turning moment on the intermediate lever while the cam means and follower means cooperate to produce a secondary turning moment on the hinge arm of magnitude varying in inverse proportion to the magnitude of the primary turning moment.
