A hinge, particularly for a seat with an adjustable back, has two hinge parts movable relative to one another about a pivot axis between a plurality of relative positions, a rotatable shaft member defining the pivot axis, and an adjusting device for adjusting the relative position between the hinge part and formed as a transmission, wherein the adjusting device includes an eccentric with an inclined surface and a bearing with an adjusting surface on which the surface of the eccentric abuts. The shaft member together with the eccentric is displacement in an axial direction with the aid of an accumulator for obtaining a radial displacement between the hinge parts. The eccentric is formed as a truncated cone, whereas the bearing has a conical bore with an inclination corresponding to the inclination of the truncated cone of the eccentric and a somewhat greater diameter than the latter, and wherein this inclination has an angle which is smaller than the static friction angle and greater than the sliding friction angle of the bearing pair formed by the truncated cone of the eccentric and the conical opening of the bearing. |
