A fitting for a vehicle seat includes a first fitting part, a second fitting part, and an eccentric, which is rotatably supported and is driven by a carrier and rotates in the circumferential direction, for driving a relative rolling motion of a spur gear and a ring gear. The eccentric has two wedge segments, which each have a convexly curved outer surface, a concavely curved inner surface, and two lateral surfaces. The lateral surfaces have a distance from each other and the inner surface and/or outer surface has a width that is less than the distance, and a transition area, which reduces the local axial dimension of the particular wedge segment from the distance to the width, is provided between at least one of the two lateral surfaces and the inner surface or the outer surface.
