Abstract
A window lift system (10) includes a support bracket structure (12) including gear structure (18, 20). A fixed rack structure (22, 24) is associated with the gear structure. A motor (16) is carried by the support bracket structure and the motor has a rotatable shaft. A gear train (28, 30, 32, 34) is associated with the shaft and with the gear structure such that rotation of the shaft moves the gear train, with the gear train driving the gear structure so as to move the support bracket structure with respect to the rack structure.

16. A window lift system comprising:
-
a support bracket structure including gear structure, the gear structure including an input gear in engagement with an output gear, a window carried by the support bracket structure, a fixed rack structure associated with the gear structure, the rack structure including a pair of racks in spaced relation, each rack having gear teeth, each of the output gear and the input gear engaging gear teeth of an associated rack, a motor having a rotatable shaft, a gear train including a pinion associated with the shaft;
at least first and second intermeshing gears disposed on associated shafts, the shafts being in parallel relation, the first gear having an axis coaxial with an axis of the input gear and the second gear having an axis coaxial with an axis of the output gear; and
a third gear engaged by the pinion, the third gear engaging the second gear,wherein rotation of the shaft and the pinion rotates the third gear which rotates the second gear causing the first gear to rotate, thereby driving the input gear and moving the support structure and window with respect to the racks. - View Dependent Claims (17, 18, 19)
