ABSTRACT:
A vehicle body window regulator of the disclosure incorporates a toggle linkage that is selectively moved between extended and overlapping positions to maintain a window in open or closed positions. The toggle linkage includes a pair of links that are pivotally connected to each other about a first axis, with one of the links pivoted about a second axis to a control member connected to the window, and with the other link selectively driven on a frame of the regulator about a third axis for movement that positions the linkage in either its extended or overlapping position. The first axis moves across a line between the second and third axes as the linkage is moved to either the overlapping or extended position, and the linkage then engages a frame stop to cause a locking action that prevents window movement due to forces applied directly to the window. A one-way clutch preferably drives the linkage and positions the window in partially open positions. This clutch also aids the locking action of the linkage in preventing window movement from its open or closed positions. A door which incorporates the window regulator has a fixed upper window and a movable lower window. The regulator frame is mounted below a downwardly and forwardly projecting portion of the fixed upper window and the control member includes a long leg that extends rearwardly for connection to the lower window as well as a short leg that is connected to the toggle linkage about the second axis. The control member is pivotally supported on the frame by a pivotal counterbalance at the juncture of its long and short legs and is pivoted by the linkage to move the lower window vertically.
