Toothed holding brake for a vehicle door and method for operating a toothed holding brake

A method for operating a toothed holding brake for a door of a vehicle, the method comprising:

• effecting a movement of an armature disk from an unlocked position into a locked position to prevent rotation of a shaft in at least one direction;
• and
• triggering a movement of the armature disk from the locked position into the unlocked position to release the rotation of the shaft in both directions,
• wherein the shaft of the toothed holding brake, at one end, forms a driver element with a driver main surface with a driver toothed rim, which has a plurality of driver teeth,
• wherein the armature disk, which has a first main surface and a second main surface, which is arranged so as to lie opposite the first main surface, an armature disk toothed rim with a plurality of armature teeth being arranged on the second main surface, the armature disk being arranged in the locked position such that the armature teeth engage into the driver teeth, to prevent rotation of the shaft in the at least one direction, and being arranged in the unlocked position such that the armature teeth are arranged spaced apart from the driver teeth to release the rotation of the shaft in both directions,
• wherein a magnet device with a magnet main surface is arranged so as to face the armature disk, the magnet device being configured to move the armature disk between the locked position and the unlocked position, the first main surface of the armature disk and the magnet main surface being arranged so as to run substantially obliquely with respect to one another in the locked position of the armature disk, and
• wherein a detection device is configured to detect the locked position and/or the unlocked position, the detection device being arranged in the region of a first side of the armature disk.
