Window raiser for a drop window

摘要

A window raiser possesses, for driving a drop window, a pivotably mounted main lever (9). However, the latter is not driven directly by a pivoting drive, but on the contrary with the interposition of a pivoting lever (3) having a guide body (7) which engages into a guide slot (8) of the main lever (9). This design makes it possible, with a constant driving torque, to increase the lifting force acting on the drop window, immediately before the drop window is closed completely. <IMAGE>
