The reduction gear is a planetary gear or includes a planetary gear (13-15).

Abstract (de)

Gegenstand der Erfindung ist ein Kraftfahrzeug-Türschloß o. dgl. mit einer Schloßfalle und einer die Schloßfalle in Schließstellung (Hauptrast und ggf. Vorrast) haltenden Sperrklinke oder mit einer integrierten Rastklinke, mit einem in beiden Drehrichtungen laufenden (reversierbaren) elektrischen Antriebsmotor (5), einem diesem nachgeschalteten Untersetzungsgetriebe (6) und einem vom Untersetzungsgetriebe (6) angetriebenen, mit der Klinke gekuppelten Betätigungshebel zum Ausheben der Klinke, wobei der elektrische Antriebsmotor (5) im Normalbetrieb nur in einer Drehrichtung, der Normaldrehrichtung, arbeitet und mit geringem Untersetzungsverhältnis über ein Normal-Betätigungselement auf die Klinke wirkt, wobei der elektrische Antriebsmotor (5) im Notfallbetrieb in der entgegengesetzten Drehrichtung, der Notfalldrehrichtung, arbeitet und mit deutlich größerem Untersetzungsverhältnis über ein Notfall-Betätigungselement auf die Klinke wirkt. Erfindungsgemäß ist das Untersetzungsgetriebe (6) als Planetengetriebe ausgeführt oder schließt ein Planetengetriebe ein. Insbesondere ist vorgesehen, daß das Untersetzungsgetriebe (6) als Kombination aus Schneckenradgetriebe, Planetengetriebe und Kurvengetriebe ausgeführt ist. <IMAGE>
