Abstract: An adjusting arrangement for inclination adjustment of a backrest of a seat has two hinges adjustably connecting the backrest with a seat part at each side and having first and second hinge levers associated with the backrest and the seat part and connected with one another by a pivot axle, and a displacing and fixing device determining the position of the hinge lever relative to one another and formed as a wobble drive including an eccentric associated with the pivot axle and retained in a force-transmitting abutment on the pivot axle, wherein the pivot axle is formed as a continuous shaft which connects the hinges with one another and has end portions supporting the hinge levers, the shaft having a recess provided in each of the end portions and receiving the eccentric, and each hinge lever surrounding the eccentric received in the recess.

Abstract: A hinge, particularly for a seat with an adjustable back rest, has two hinge parts and an adjusting and fixing transmission including an internal gear and a spur gear therebetween and an axle provided with an eccentric, wherein the spur gear and the internal gear are formed as cup-shaped members connected for joint rotation with the hinge part, and the cup-shaped member forming the spur gear has teeth on its outer surface, whereas the cup-shaped member forming the internal gear has teeth on its inner surface.
