Embodiment Construction

[0031] figure 1 A vehicle seat 1 is shown schematically with a seat part 2 and a backrest 3 connected to the seat part 2 , wherein the inclination of the backrest can be adjusted. The seat part 2 is arranged longitudinally adjustable via a rail arrangement 4 on a vehicle floor of a vehicle (not shown) and is height-adjustably connected to the rail arrangement 4 via a rocker pair 51 , 52 .

[0032]Rocker pairs 51 , 52 each formed by two parallel rockers are pivotally connected on the one hand to the seat part 2 and on the other hand to the rail arrangement 4 and in this way are connected to the seat part 2 and the rail arrangement. The arrangements 4 together form a quadruple linkage to allow adjustment of the seat height of the seat part 2 relative to the rail arrangement 4 . For this purpose, the pair of rockers 51 , 52 can be pivoted parallel to each other along the pivoting direction V to raise or lower the seat part 2 relative to the rail arrangement 4 by pivoting the pai...

Abstract

The invention relates to a vehicle seat comprising a seat part for providing a seat surface for a seat occupant, a guide track arrangement for the longitudinally adjustable arrangement of the vehicle seat in a vehicle and a height adjustment device comprising a plurality of rockers which are pivotably coupled to the seat part and the guide track arrangement and which connect the seat part to the guide track so as to be adjustable in height, and a drive unit powered by an electric motor for driving a first rocker of the plurality of rockers. The drive unit has an output pinion which engages in a toothing of a tooth segment and can be made to move in rotation with respect to the tooth segment in order to set the seat height of the seat part relative to the guide track arrangement. To this end the output pinion (531) is disposed on the first rocker (51a) and the tooth segment (552) is disposed immovably on the guide track arrangement (4) or on the seat part (2). In this way a vehicle seat is created which also enables the arrangement of a drive unit powered by an electric motor in a space-saving manner on a so-called tunnel side of a vehicle seat and at the same time can provide a reliable support for loading forces.

Description

technical field [0001] The invention relates to a vehicle seat according to the preamble of claim 1 . [0002] The vehicle seat includes: a seat portion providing a seating surface for a seat occupant; a rail arrangement for longitudinally adjustably arranging the vehicle seat in the vehicle; and a height adjusting device for adjusting the vehicle seat seat height. The height adjustment device includes a plurality of rockers pivotally coupled to the seat portion and the rail arrangement, wherein the rockers connect the seat portion to the rail arrangement to enable height adjustment. To drive a first of these rockers and to adjust the seat part relative to the rail arrangement to adjust the height of the seat, the height adjustment device comprises an electric drive unit comprising an output pinion, the output The pinion engages in the toothing of the tooth segment and is rotatable relative to said tooth segment to adjust the seat height. Background technique [0003] In ...
