• the coupling carriage When the sliding door moves out of the middle position, the coupling carriage is moved in the respective opening direction via corresponding driver projections on the sliding door and, depending on the direction of movement, interacts with one of the two unidirectional draw-in devices.
• a pull-in spring of the respective draw-in device is tensioned to a point at which a catch of the draw-in device, on which the coupling carriage engages, is tilted into a locking position.
• the coupling from the coupling carriage to the intake device is released.
• the coupling element moves due to a sloping guide within the feeder away from the Mitauervorsprung the sliding door and is thereby decoupled from the sliding door.
