ABSTRACT:
A cable window regulator assembly is mounted to a carrier panel. At least four pulleys are spaced around the carrier panel, each rotating around an axis substantially perpendicular to the carrier panel. A lift plate assembly is displaced away from the carrier panel and is constrained to travel in a closure plane solely by the closure panel. An upper and a lower cable is trained around a first pair of the pulleys. One end of each of the upper and lower cables is affixed to a drive assembly; the other end of the upper and lower cables is affixed to the lift plate assembly on opposite sides near opposing edges of the lift plate assembly. Engaging the drive assembly causes the lift plate assembly to move towards either an open or a closed position. A follower cable, affixed to the lift plate assembly at opposite sides thereof and trained about a second pair of the pulleys, maintains coordinated travel of the lift plate assembly.
