ABSTRACT:
The window winder for a slidable window, especially a window capable of being lowered into the window shaft of an automobile, has a threaded cable displaceably guided in a tension resistant and compression resistant manner in a guide tube. The threaded cable engages, in a two part drive casing, a drive pinion which is non-rotatably keyed to a drive shaft journalled in the two half casing of a gear wheel drive equipped with a drag spring brake. The threaded cable is directly or indirectly connected to the window by one or more entraining devices fixed to the cable and penetrating through a longitudinal slit in the guide tube. The guide tube is a slit metal tube in the region of the path of movement of the entraining devices and elsewhere is a plastic tube connected to the drive casing and the metal tube in a non-displacing, non-rotatable manner by means of sleeves injection molded onto the plastic tube. The two parts of the drive casing are injection molded from plastic material and their parting plane is situated outside the threaded cable passing through the casing and outside the drive pinion between the drive pinion and the drag spring barke. The guide duct guides the threaded cable substantially in alignment with the internal surface of the guide tube and open towards the drive pinion and the parting plane is disposed in one casing part and the sleeves which receive the guide tube are formed integrally with the casing part.
