Abstract: A bowden-cable window-lifter drive including a cable reel in a covered housing. The reel is provided at its end face with drive pins and a coupling component connected to it so as to rotate jointly with a crank bolt engaging between the drive pins. The drive is characterized in that the crank bolt and the coupling component are two separate parts which, in the fully assembled state, are joined by a serration or the like to rotate together. In a pre-assembled condition, only the cable reel, the coupling component and a braking spring are contained in the cable-reel housing. Following installation of the window lifter in the vehicle door, the crank bolt is inserted from the door inner wall into the drive until the serrations at the crank bolt and at the coupling component are aligned.

Abstract: A motor drive unit for a cable window regulator of reduced depth dimension. The drive unit includes two subassemblies which include elements which are combined to form integral assembly pieces. In this manner, the housing of the subassembly can be reduced in dimension and provide a motor drive unit of overall reduced dimension.

Abstract: A motor drive unit for a window regulator. The drive unit is divided into two subassemblies. The first subassembly includes a driven worm gear and a bearing pin. The second subassembly includes a worm wheel having an extended sheath on which a cable driving drum is mounted. When the two subassemblies are fitted together, the worm wheel and worm gear mesh and the bearing pin extends through and supports the worm wheel, sheath and cable drum.
