Abstract

Die Erfindung betrifft ein Schließzylinder, insbesondere für Türschlösser von Kraftfahrzeugen, mit einem inneren, Zuhaltungen aufweisenden Zylinder, der mit einer den Zylinder umschließenden Freilaufhülse zusammenwirkt, wobei die Freilaufhülse den Zuhaltungen entsprechende Ausnehmungen aufweist und in einem äußeren, festen Gehäuse drehbar gelagert ist, ferner mit einer Kupplungseinrichtung und einem Rastmittel, welche bei einem definierten Drehmoment auf die Freilaufhülse die Rastverbindung zwischen dem Gehäuse und der Freilaufhülse lösen und zugleich eine Entkopplung zwischen dem Zylinder und einem nachgeschalteten Schloss steuern, sowie mit einer auf den Zylinder wirkenden, bevorzugt als Schenkelfeder ausgebildeten Rückstellfeder. Eine einfache, baulich günstige und eine zuverlässige Rückstellfunktion herstellende Schlosskonstruktion wird dadurch erzielt, dass die Rückstellfeder (30) funktionell zwischen den Zylinder (12) und die Freilaufhülse (14) eingeschaltet ist.

The invention relates to a lock cylinder, in particular for door locks of motor vehicles, having an inner, tumblers having cylinder which cooperates with a cylinder enclosing the freewheel sleeve, wherein the freewheel sleeve has the tumblers corresponding recesses and is rotatably mounted in an outer, fixed housing, also with a coupling device and a latching means, which solve the latching connection between the housing and the freewheel sleeve at a defined torque on the freewheel sleeve and at the same time control a decoupling between the cylinder and a downstream lock, as well as acting on the cylinder, preferably designed as a torsion spring return spring. A simple, structurally favorable and a reliable reset function producing lock construction is achieved in that the return spring (30) functionally between the cylinder (12) and the freewheel sleeve (14) is turned on.
