A latching fitting for a seat of a motor vehicle, comprising: a base plate which has a plurality of mounting projections; a cover plate rotatable relative to the base plate having an inner toothing; a plurality of blocking arms (40, 140) equally oriented in circumferential direction, each mounted on one of the mounting projections and pivotable between an unlocked position, in which a rotation of the cover plate relative to the base plate is possible, and a locked position, in which a rotation of the cover plate relative to the base plate is blocked; an actuating plate rotatable relative to the base plate, by means of which the blocking arms (40, 140) are movable between the unlocked position and the locked position; a control ring controlling the movement of the blocking arms (40, 140), which has an inner circumferential surface, and a spring which biases the actuating plate in direction of the locked position; the inner toothing having first blocking teeth which have a vertex and are designed in an asymmetrical manner relative to a radial axis which runs through the vertex; each of the blocking arms (40, 140) comprising a blocking portion which has second blocking teeth which mesh with the first blocking teeth in the locked position; each of the blocking arms (40, 140) forming a first control curve which has a first unlocking region, a first locking region, and a first supporting region; the actuating plate forming a second control curve co-operating with the first control curve which has a second unlocking region, a second locking region, and a second supporting region; the inner circumferential surface of the control ring forming a third control curve which has an adjustment region and at least one latching region, at least one of the blocking arms (40, 140) having a control catch which is co-operating with the third control curve, and the control ring having an outer circumferential surface with a toothing for fixation to the base plate or to the cover plate. a base plate which has a plurality of mounting projections; a cover plate rotatable relative to the base plate having an inner toothing; a plurality of blocking arms (40, 140) equally oriented in circumferential direction, each mounted on one of the mounting projections and pivotable between an unlocked position, in which a rotation of the cover plate relative to the base plate is possible, and a locked position, in which a rotation of the cover plate relative to the base plate is blocked; an actuating plate rotatable relative to the base plate, by means of which the blocking arms (40, 140) are movable between the unlocked position and the locked position; a control ring controlling the movement of the blocking arms (40, 140), which has an inner circumferential surface, and a spring which biases the actuating plate in direction of the locked position; the inner toothing having first blocking teeth which have a vertex and are designed in an asymmetrical manner relative to a radial axis which runs through the vertex; each of the blocking arms (40, 140) comprising a blocking portion which has second blocking teeth which mesh with the first blocking teeth in the locked position; each of the blocking arms (40, 140) forming a first control curve which has a first unlocking region, a first locking region, and a first supporting region; the actuating plate forming a second control curve co-operating with the first control curve which has a second unlocking region, a second locking region, and a second supporting region; the inner circumferential surface of the control ring forming a third control curve which has an adjustment region and at least one latching region, at least one of the blocking arms (40, 140) having a control catch which is co-operating with the third control curve, and the control ring having an outer circumferential surface with a toothing for fixation to the base plate or to the cover plate.
