Abstract

A vehicle seat has a cushion integrated into a seat part and/or a seat back. The cushion has a ventilation layer through which air can flow and a cushion cover stretched over the cushion surface facing the seated individual. A plurality of electrically driven miniature fans which are located in air channels to blow air into the ventilation layer that terminate at the underside and rear of the cushion facing away from the cushion cover are provided. The air channels extend up to the ventilation layer. To optimize the ventilation efficiency of the seat ventilation, exhaust air channels are provided in the cushion that extend from the ventilation layer up to the underside or rear of the cushion and terminate freely there.
