But it must also be operated manually at least a motor vehicle door lock of the central locking device be possible if the central locking device fails and the motor vehicle door lock from the outside with the help of a key or from the interior out for the purpose of unlocking by the Internal operating lever is operated. This is what the control section does over which the component of the power chain, which in the spiral groove borders, from the locking end position in the unlocking end position can be moved.

Bei dem bekannten Kraftfahrzeugtürverschluß, von dem die Erfindung ausgeht (EP 0 059 658, insbesondere Fig. 6), ist die Anordnung so getroffen, daß der Kontakthebel für die Steuerung und Stromversorgung des elektromotorischen Antriebes mit einem Betätigungsstift in die Spirale der Steuernut einfaßt. Das ist aufwendig und gleichsam ein Umweg, wenn auch vorgesehen ist, daß der Kontakthebel zugleich das Eingangsorgan für die beschriebene manuelle Betätigung darstellt.In the known motor vehicle door lock, of which the Invention is based (EP 0 059 658, in particular Fig. 6) the arrangement made so that the contact lever for the Control and power supply of the electromotive Drive with an actuating pin in the spiral of Bordering control groove. This is complex and quasi a Detour, if it is also provided that the contact lever at the same time the input organ for the described manual Represents activity.

Der Erfindung liegt die Aufgabe zugrunde, bei einem Kraftfahrzeugtürverschluß des eingangs beschriebenen Aufbaus die Hebelkette, und insbesondere die Maßnahmen für die manuelle Betätigung zu vereinfachen.The invention is based, with one Motor vehicle door lock described above Building the leverage chain, and especially the measures for to simplify manual operation.

This avoids the detour via the Contact lever.

Im einzelnen bestehen im Rahmen der Erfindung mehrere Möglichkeiten der weiteren Ausbildung und Gestaltung. Eine bevorzugte Ausführungsform der Erfindung ist dadurch gekennzeichnet, daß das Abtriebselement als ebene Abtriebsscheibe ausgeführt ist, auf der oder in der die Spiralnut und der Steuerabschnitt angeordnet sind, und daß die Abtriebsscheibe sich um einen Mittelpunkt dreht, zu dem der Steuerabschnitt im wesentlichen radial angeordnet ist. Es besteht aber auch die Möglichkeit, das Abtriebselement als eine zylindrische Abtriebswalze auszuführen, auf deren Mantel die Spiralnut schraubenwendelförmig verläuft, wobei der Steuerabschnitt im wesentlichen parallel zur Achse der Walze angeordnet ist.There are several in the scope of the invention Opportunities for further training and design. A preferred embodiment of the invention is thereby characterized in that the output element as a plane Output pulley is carried out on or in which the Spiral groove and the control section are arranged, and that the driven pulley rotates around a center to which the control section is arranged essentially radially. But there is also the possibility of the output element run as a cylindrical driven roller, on the Sheath the spiral groove runs helically, whereby the control section is substantially parallel to the axis of the Roller is arranged.
