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 arrangement so as to be adjustable in height, and a electromotive drive unit 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 set into rotation with respect to the tooth segment for adjusting the seat height of the seat part relative to the guide track arrangement. To this end, the output pinion is arranged on the first rocker and the tooth segment is arranged stationary on the guide track arrangement or on the seat part.
