Abstract

A motor-vehicle door latch has a housing and a locking mechanism in the housing having an inside locking lever displaceable between a locked position in which the latch is locked and an unlocked position in which the latch is unlocked. An output element rotatable about an axis on the housing is formed with a spiral main groove having a pair of ends and with a transverse connecting groove extending between the ends. A pin mounted directly on the locking lever rides directly in the spiral groove. A reversible electric motor can rotate the output element so that the pin travels between the ends of the spiral groove for displacing the locking lever into the locked position when the pin engages one of the groove ends and for displacing the locking lever into the unlocked position when the pin engages the other of the groove ends. A locking element connected to the inside locking lever displaces same manually between its positions with movement of the pin along the connecting groove between the spiral groove ends.
