<p>An automobile window lift mechanism having a lift arm assembly (24) for raising and lowering a window (16) along a travel path between an open and closed position, a pinion gear (26) for supplying rotative force from a motor (30) or manual handle for actuating the lift arm assembly (24), and a gear train (28) interconnecting the pinion gear (26) and the lift arm assembly (24) to provide a substantially instantaneous increase in mechanical advantage and window closing force as the window engages an upper seal (20) in the closed position. The gear train (28) 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. <IMAGE></p> |
