A motor vehicle door lock comprises a ratchet-type mechanism having a pawl and a rotary latch. The motor vehicle door lock is also provided with a release lever for the ratchet-type mechanism and at least one actuation lever and a blocking element. The blocking element brings about a mechanical connection during normal operation and a mechanical separation, when operating in the event of an accident, between the actuation lever and the release lever. According to the invention, the blocking element is configured as a coupling lever mounted on the actuation lever, which pivots independently from the actuation lever applied with spring force when operating in the event of an accident.
