Abstract
An automobile window lift mechanism having a lift arm assembly for raising and lowering a window along a travel path between an open and closed position, a pinion gear for supplying rotative force from a motor or manual handle for actuating the lift arm assembly, and a gear train interconnecting the pinion gear and the lift arm assembly to provide a substantially instantaneous increase in mechanical advantage and window closing force as the window engages an upper seal in the closed position. The gear train includes a gear reduction configuration and/or an increased lever effort arm to increase the mechanical advantage only during the closing movement of the window as it engages the upper seal.
