an inclination adjustment fitting for seat backs of vehicle seats includes two fitting parts that are connected in a swiveling manner relative to each other via a wobble mechanism driven by an eccentric . the eccentric is formed from an eccentric ring and two wedge segments that are arranged in mirror image and set apart from each other and that in regions cover the circumference of the eccentric ring . the wedge segments are pressed apart by a spring acting against their one end faces for increasing the eccentricity and which are capable of being acted upon against the force of the spring by driving elements between the other end faces . the spring is supported on the eccentric such that the wedge segments occupy a defined position relative to the eccentric ring .
