ABSTRACT:
A window regulator for a motor vehicle is provided. The window regulator is arranged to provide a controlled movement of a window pane between a raised position and a lowered position, the window pane being guided on two opposite edges by guide means. The window regulator comprises a lifting arm slidingly connected to the window pane at one end and pivotable about a point near its other end, means to produce rotation of the lifting arm about the point to produce said controlled movement of the window pane and a control arm slidingly connected to the window pane at one end and constrained at its other end to move in a pre-determined manner in response to pivotal movement of the lifting arm about the said point. The lifting arm and the control arm are pivotally interconnected intermediate their respective ends at a position spaced from the said point and means are provided to bias the window pane towards one of the guide means at least when the window pane approaches its raised position.
