Die Steuerung für das Aus- und Einrücken der Brems- und
Feststelleinrichtung des Kraftwagentürfeststellers umfaßt eine mit der
Spindel 2 im Eingriff befindliche und drehbar in einer vorderen Abteilung
24 des Feststellergehäuses 3 gelagerte Steuermutter 25, eine dieser

bzw. 22 entspricht, relativ zum feststehenden Teil 19 des
Feststellergehauses 3 verschoben wird, so daß die Steuermutter 25 durch die
Spindel 3 angetrieben wird, obwohl sich die Brems- und
Feststelleinrichtung noch in ihrer eingerückten Haltestellung befindet. Die
so erzwungene Drehbewegung der Steuermutter 25 wird vermittels der
Viskokupplung 26 in ein Antriebsmoment für das Ritzel 27 umgewandelt,
welches seinerseits vermittels des Zahnrades 29 einen Rotationsantrieb der
Excenterwelle 28 bewirkt, so daß der an der Excenterwelle 28 angeordnete
Verstellexcenter 8 entgegen der ihn beaufschlagenden Wickelfeder 10, 11

der Tür das während der Türbewegung durch die Kombination Spindel 2
und Steuermutter 25 erzeugte Drehmoment zusammen, so daß die
Viskokupplung 26 keine Antriebsleistung mehr auf das Ritzel 27 übertragen
kann, mit der Folge, daß die Wickelfedem 10, 11, die Excenterwelle 28 und
