Abstract

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.
