Abstract:
A door-locking device, in particular for a motor vehicle, comprising an inside door-handle element moveable from a closed position into an open position by an inside door handle being actuated, having an outside door-handle element which moveable from a closed position into an open position by an outside door handle being actuated, and a driver element couplable in a form-fitting manner to the inside door-handle element and/or the outside door-handle element by a coupling and moveable from an uncoupled closed position into a coupled open position by the inside door-handle element and/or the outside door-handle element and by means of which, in the coupled state, a catch of a door lock can be actuated, wherein the coupling is driveable to move counter to a spring force from its coupled position into its uncoupled position by an uncoupling element, and an authorization signal can be directed in a contactless manner to a control unit by a mobile authorization unit, and the outside door handle is assigned a switch by means of which, when actuation of the outside door handle begins, a signal is produceable and directed to the control unit and, when said signal and the authorization signal are present, a drive is activateable by the control unit such that the uncoupling element is driveable to move from its uncoupled position into its coupled position by the drive, wherein displacement of the uncoupling element between the uncoupled position and coupled position is transmittable to a locking button (15) via a transmission element, that the transmission element or the locking button (15) is forced into its respective displacement end position by a bistable spring element, and such a clearance for movement (33) is provided between the uncoupling element and transmission element that, when the movement of the uncoupling element from the uncoupled position into the coupled position begins, the uncoupling element executes a displacement, which is free of the transmission element, until a just sufficiently reliable form-fitting coupling between the driver element and the outside door-handle element has taken place.
