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.

A vehicle seat, comprising:
- a cushion integratable into at least one of a seat part and seat back, said cushion including a ventilation layer through which air is flowable, the ventilation layer being a coarse-mesh spacing knit;
- a plurality of air supply channels arranged in the cushion, first sides of which terminate at a side of the cushion opposite a side facing a seating surface and second sides of which extend up to the ventilation layer;
- a plurality of electrically powered miniature fans, one fan being arranged in each air supply channel for blowing air into the ventilation layer;
- exhaust air channels provided in the cushion, said exhaust air channels extending from the ventilation layer and terminating freely at one of lower and rear sides of the cushion.
A vehicle seat, comprising:
- a ventilation layer formed in the vehicle seat;
- air supply channels arranged to supply air to a first side of the ventilation layer which is opposite to a second side facing a seating surface of the vehicle seat;
- at least one exhaust channel receiving air from the first side of the ventilation layer, said exhaust channel having an exhaust end apart from the air supply channels to maintain incoming and outgoing air streams separate from one another, wherein the air supplied to the first side and the air received from the first side flow in substantially different directions.
