1. A door lock for a motor vehicle door, the door lock comprising:
a locking mechanism including a catch and a pawl; and
a closing device which acts on the locking mechanism, wherein the closing device has at least one actuation lever that is motor-driven, a driving pawl which interacts with a locking mechanism component, a transmission lever, and at least one unlocking element for mechanically interrupting a force flow between the actuation lever and the driving pawl, wherein the unlocking element acts on a coupling element, which separates the closing device without exerting a force for an emergency unlocking function during which the coupling element is converted from an engaged state to a disengaged functional position,
wherein the coupling element, the actuation lever, and the driving pawl are rotatably mounted on the transmission lever,
wherein in the engaged state, the actuation lever engages the coupling lever such that movement of the actuation lever drives movement of the transmission lever to drive the driving pawl to act on the catch, and
wherein in the disengaged state, the coupling lever is disengaged from the actuation lever such movement of the actuation lever does not drive movement of the transmission lever.
