Zusammenfassung: | A hinge based counterbalance mechanism for operating a hinge of a closure panel of a vehicle to assist in opening and closing of the closure panel between a closed position and an open position about a pivot axis, the hinge drive mechanism including: a hinge having a body side portion for connecting to a body of the vehicle and a panel side portion for connecting to the closure panel, the body side portion and the panel side portion coupled via the pivot axis; a torsion element having a fixed end coupled to the body and a free end coupled to the body side portion, the fixed end inhibited from rotating relative to the free end and the free end able to rotate about a torsion axis of the torsion element; and a mechanical coupling mechanism coupling the free end to the panel side portion, the mechanical coupling mechanism providing for variability in torque output of the torsion element applied from the torsion element to the panel side portion as the hinge moves between the open position and the closed position. |
