ABSTRACT:
The window in the door of a motorcar may be raised and lowered by means of a lifting mechanism including an electric motor connected to a speed reducing, worm gear transmission and a lifting arm turned by the output shaft of the transmission through further speed-reducing gears. The stroke of the window movement is limited by cooperating fixed, but adjustable abutments on supporting structure and an abutment connected to the output shaft of the worm gear transmission for joint rotation.
