Abstract

A vehicle seat has a cushion integrated in a seat part and/or a backrest, which cushion has a ventilation layer, through which air can flow, and an air-permeable cushion cover spanning the cushion surface. The seat also has at least one ventilator arranged below the cushion for blowing air into the ventilation layer. In order to provide a ventilated vehicle seat construction at reasonable cost for vehicles of the medium to lower price range, the ventilation layer is constructed as an air-permeable cushion support which rests on a cushion carrier only by way of intermediate placement of an air-impermeable pressure distribution layer. The pressure distribution layer has at least one inflow opening for the ventilation air on which the ventilator is arranged below the air distribution layer.
