Counterbalanced rear closure for a vehicle
In a preferred embodiment, a dual panel vehicle rear closure assembly is actuated by a cable drive assembly. Cables push a rear panel upward from a closed position to a second position above the roof. The cables may then push both panels forward toward a third position to open a rear opening in the roof. A motor pushes the cables through channels to slide the rear panel. Free ends of cables are guided into cable return tubes. Compression assist springs in the tubes are compressed by the cables when the rear panel is in its closed position and provide a counterbalance force to assist in opening the panel. The compression springs may be shorter than the full cable. The shorter springs can be made stronger for applying the balancing forces to the lower portion of the panel travel.
