Abstract

A door latch for a motor-vehicle central-latch system has a housing, a locking element displaceable on the housing between a door-bolt-holding position and a door-bolt-releasing position, and a pawl displaceable on the housing between a retaining position holding the locking element in its bolt-holding position and a freeing position allowing the locking element to assume its bolt-releasing position. A release lever pivotal on the housing into an actuated position can put the paws into the freeing position. A outside operating lever is pivotal on the housing between actuated and unactuated positions and a main locking lever is pivotal on the housing by an electric motor between locked and unlocked positions. A link engageable between the main locking lever, the outside operating lever, and the release lever serves for, when the main locking lever is in the unlocked position and the outside operating lever is in its unactuated position, coupling the outside operating lever to the release lever to displace same into its freeing position on movement of the outside operating lever into its actuated position. When the main locking lever is in the locked position and the outside operatin…
