a) a first fitting part affixable to a vehicle seat, in use, and a second further fitting part affixable to a vehicle backrest, in use, and which first and second fitting parts can be pivoted relative to one another around a pivoting axis, in use;

b) the first fitting part and the second fitting part include respective gearings which provide a part of a wobble gearing and roll on one another under the influence of an eccentric device which is rotatable around the pivoting axis, and which includes an eccentric ring, on which two wedge segments with a wide end surface and a narrow end surface that cover regions of the eccentric ring lie, arranged in a mirror image, and which wedge segments are forced away from one another in the sense of an increase in eccentricity by a spring element that rests against the wide end surface of the wedge segments;

c) the eccentric device bears the first fitting part, while the second fitting part bears the eccentric device;

d) a rotating adjustment element provided for the eccentric device and having an irregular recess for a fixed connection with an actuating rod;

e) carrier elements for the fixed connection of the eccentric ring with the rotating adjustment element being provided between narrow end surfaces of the wedge segments;

f) an additional carrier element being provided for a fixed connection of the eccentric ring with the rotating adjustment element is provided between wide end surfaces of the wedge segments; and

g) the rotating adjustment element being guided in a radially movable manner on the eccentric ring by means of the carrier elements and by the additional carrier element.
