Abstract

A motor-vehicle door latch has a housing, a lock fork on the housing engageable with a door bolt, and a release pawl engageable with the fork. An actuating mechanism is connected to the release pawl via a coupling part displaceable on the housing so that in a decoupling position of the part actuation of the actuating mechanism does not affect the release pawl. A central locking element is displaceable on the housing generally parallel to a predetermined direction, is formed with a cutout opening transversely of the direction and having locking and unlocking flanks directed oppositely at least generally in the direction, and is formed to each side of the cutout with an abutment surface directed generally perpendicular to the direction. A locking mechanism jointly movable with the locking element is connected between the central locking element and the coupling part for displacing the coupling part into the decoupling position on displacement of the central locking element into its locked position and for displacing the coupling part into the coupling position on displacement of the central locking element into the unlocked position. A drive body rotatable about a drive axis has an e…
