ABSTRACT:
A motor-vehicle door latch has a lock fork engageable with a door bolt and a release pawl engageable with the fork. A lever mechanism connected to the release pawl can operate the release pawl. A locking element pivoted on the housing about an element axis and operatively connected to the lever mechanism is formed with an outwardly open notch and is displaceable for decoupling the lever mechanism from the release pawl in the locked position of the locking element and for coupling the lever mechanism to the release pawl in the unlocked position of the locking element. A cutout lever is pivotable on the housing about a cutout axis and a drive body rotatable about a drive axis parallel to the element and cutout axes has an eccentric pin extending parallel to the axes. The pin is engaged in the notch and is engageable with the cutout lever. An inside handle is permanently connected to an inside latching lever to actuate it, is operatively connected to the cutout lever, and has an end engageable with the mechanism to actuate same only in the normal position of the cutout lever. This inside latching lever is operatively unengageable with the mechanism in the cutout position of the cutout lever. A motor can rotate the drive body and thereby orbit the pin about the drive axis to displace the cutout lever between the cutout and normal positions, and to displace the locking element between the locked and unlocked positions.
