Abstract

A motor-vehicle door latch has a latch mechanism, a locking lever movable between a locked position and an unlocked position, a motor drive, and a blocking lever engageable with the locking lever. The locking lever can be decoupled from the blocking lever during fast unlocking so that the locking lever can move into its unlocked position. A spring-loaded force-transmitting lever is coupled to the drive so as to, when displaced thereby in one direction, entrain the locking lever for fast unlocking and so as to, when displaced by the drive in an opposite direction, deflect.
