1. A motor vehicle door lock comprising:
a locking mechanism that includes a rotary latch and a pawl,
an electric drive for operating the locking mechanism, and
an actuating lever chain that is implemented between the electric drive and the locking mechanism to selectively couple the electric drive and the pawl of the locking mechanism,
wherein the actuating lever chain includes a coupling element and a link through which the coupling element is moveable from a consistently assumed coupled position in which the electric drive and the pawl are coupled to a decoupled position in which the electric drive and the pawl are decoupled with the aid of a manually actuatable emergency actuating element,
wherein the emergency actuating element acts on the coupling element by moving a portion of the coupling element through the link, and wherein the coupling element includes a pin, and the emergency actuating element engages the pin of the coupling element and guides the pin through a slot within the link to move the pin between the coupled position and the decoupled position.
