Abstract
A central locking drive ( ) serves for the actuation of various locking functions of a door lock, especially in motor vehicles' and has two drive members ( ), which are each adjustable between an inoperative position and an activated position. In order to be able to actuate additional locking functions' such as child safety for example, automatically, an additional drive member or expensive detection of intermediate positions of the two drive members has hitherto been necessary. In order to avoid this expense there is provided an operating element ( ), which is moveable between a neutral position and at least one operating position, the attainment of a particular operating position of the operating element ( ) being dependent upon the order in which the two drive members ( ) are activated. The operating element is displaced, for example, by interacting cam elements on the operating element ( ) and the drive members.
