ABSTRACT:
A window regulator for driving two sliding window panes, such as of a truck rear window, in opposing directions has a housing containing two linear actuator, one driving each of the sliding panes. The first actuator has opposite ends engaged with a drive drum and a midpoint engaged with the first sliding pane, and the second linear actuator has opposite ends engaged with the drive drum and a midpoint engaged with the second sliding panes. The drive drum has two parallel, spiral grooves, one receiving each of the linear actuators. The first and second linear actuators pass around pulleys and guide blocks attached to the housing and follow separate paths within the housing such that rotation of the drive drum in one direction pulls on respective first ends of the first and second linear actuators to draw the sliding panes toward one another, and rotation of the drum in the opposite direction pulls on respective second ends of the linear actuators to draw the panes away from one another. The regulator housing is adapted to be attached to the fixed panes of the window assembly outboard of the sliding panes or to some other stationary structure of the vehicle surrounding the window opening.
