Motorized window regulator,

in particular to the. Installation in doors of motor vehicles

The innovation relates to a motorized window lifter, especially for installation in doors of motor vehicles, with a built-in electric motor in the motor vehicle and a switch at least with a first switch position "raise window" and a second switch position "lower window", its input connections alt a supply voltage source and J 15 whose output terminals are permanently connected to the input terminals of the electric motor.

If no special measures are taken, the lifting of a window in a motor vehicle door requires a greater force than the lowering of this window. The electric motor of a motorized window regulator would therefore raise the window pane much more slowly than it would reduce. To counteract this condition, attempts have already been made to turn the motor through when lifting the disc

a coil spring to assist in lowering the Disk works against the motor and is pretensioned in the process.

The task of the present innovation is to counter this Simpler means that act constantly over long periods of operation, on the one hand, is the closing speed of the window and, on the other hand, too abrupt opening of the window pane in the motor vehicle door impede.

The solution to this problem is possible with a motorized window regulator of the type mentioned in the introduction in that a series resistor is attached to the electric motor which is firmly connected between the one output terminal of the second switch position "lower window" of the container and the one input terminal of the electric motor; characterized check blank in a simple manner different load characteristics of the motorized drive in the Tieise achieve, on the one hand, the full engine power "lift window" in operation can be inserted and on the other hand Fenstersehsibe "SISS (operation" Open window "is not too quickly moved down ^V is.

The series resistor 1 is attached to the electric motor 3.

Advantageously, the electric motor 3 is set in the sense of a maximum closing speed and the series resistor 1 in the sense of a certain ratio of ι closing and opening time of the window 7, whereby sweckaäßigsrvfeiie such a definition of the series resistor 1 is provided, the closing and opening times of the window 7 are the same size.

( ) Fig. 2 shows in more detail the structure of the switch 2 for the case that the series resistor 1 is attached to the electric motor 3. The control knob of switch 2 shown at the top left is shown in the neutral position 0. If it is moved up to the H position ("raise window"), the DC voltage source 9 is connected to the output terminals 21 and 22 of the switch 2. The output terminals 21 and 22 of the switch 2 are firmly and directly connected to the input terminals 31 and 32 of the electric motor 3 without the interposition of the series resistor 1.
