Abstract
A vehicle seat has an upholstery which is integrated in both eat part and in the backrest. A ventilation layer is provided through which air can flow, and an air-permeable upholstery cover spans the surface facing the sitting person, as well as having devices for ventilating the ventilation layer. For improving the sitting climate comfort, which also includes a rapidly effective cooling of the seat surfaces heated by sun radiation when the vehicle is entered and the removal of the transpiration moisture, and also for avoiding disturbing air connection hoses between the vehicle seat and the air-conditioner, the ventilation layer is arranged on an upholstery layer. Devices for ventilating the ventilation layer have a plurality of electrically driven miniature fans integrated in the upholstery layer. One miniature fan respectively is arranged in an air duct penetrating the upholstery layer from the underside to the ventilation layer. The distribution of the air ducts takes place so that a uniform, area-wide ventilation of the ventilation layer is ensured.
