Abstract

The invention presents a vehicle seat with an adjusting mechanism, for example with a height adjustment of the seat area or with a length adjustment of a longitudinal guiding (20, 22), whereas the adjusting mechanism is provided with an electromotor (36), a step-down gear (34) and an adjusting device having a first adjusting element as well as a second adjusting element which may be adjusted relative to the first adjusting element. The adjusting mechanism is additionally provided with a constantly engaged brake (38) that is leading to a braking moment in both senses of rotation of the electromotor (36), the braking moment being calculated so as to be considerably smaller than the active driving moment of the electromotor (36) but so as to be bigger than the passive torques occurring during normal operation of the vehicle due to all kinds of acceleration and loads.
