A motor vehicle door closure includes a locking mechanism having a rotary latch and a locking pawl for locking the rotary latch. The door closure also includes a blocking pawl for blocking the locking pawl when engaging, a release lever for releasing the locking pawl, and a locking lever that blocks the locking mechanism at least in the event of acceleration forces of a predetermined magnitude occurring, for example in an accident (impact). The release lever and the locking lever are arranged about an axis. This results in a particularly simple lock design.
