An arrangement for adjustment of seats has a seat support which is connected with rails associated with a vehicle bottom. The front end region of each lateral support member is connected via a swinging member with the associated rail in a pivotable manner. Each swinging member has a toothed rack in which a pinion supported in each lateral support member engages, and the pinion is arranged on a shaft extending through the lateral support members. An actuatable locking device fixes the pinion in the toothed rack together with the seat support in selected positions in stepped manner. For lifting or lowering the front and the rear seat region independently of each other, or together with each other, the rear end region of each lateral support member is also supported on a shaft extending through the seat support and fixedly connected with a pinion associated with each lateral support member. Each pinion engages in a vertically extending toothed rack fixed on each rail, wherein the pinion arranged on the same shaft is fixable by a locking device in selective height positions of the seat support in stepped manner.

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.
