ABSTRACT:
A vehicle window regulator is provided for lifting a window and lowering the window for retraction into a window well in a vehicle door. In the best embodiment the window is supported for lifting and lowering by first, second and third flexible cables, each of which is attached at one end to a take-up mechanism mounted on the window. The first and second cables at the end opposite the take-up mechanism are mounted to an upper portion of the body of the vehicle door, and the third cable at the end opposite the take-up mechanism is mounted to a lower portion of the body of the vehicle door. For lifting the window, the take-up mechanism shortens the first and second cables and simultaneously lengthens the third cable. For lowering the window, the operation is reversed. For vehicle windows and doors having an outwardly convex curvature whereby when the window is raised and lowered the take-up mechanism mounted on the window describes an arcuate path, the third flexible cable is pivotally mounted at the point of attachment to the lower portion of the body of the vehicle door so as to permit lateral deflection of the third flexible cable to maintain its alignment with the take-up mechanism, and; pivotal cable guide pulleys for guiding the first and second cables are attached to the lower portion of the window for guiding the first and second cables to maintain alignment with the take-up mechanism.
