Estimating the term…
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.
Vehicle seat having a seat part and a backrest, an upholstery which is integrated in at least one of the seat part and the backrest and which has a ventilation layer of material through which air can flow, the ventilation layer consisting of a large-meshed spaced knit and which has an air-permeable upholstery cover spanning a surface facing a seat occupant, and devices for ventilating the ventilation layer, wherein the ventilation layer covers an upholstery layer at least in a body contact area over an entire surface thereof the ventilation devices comprising a plurality of electrically driven miniature fans integrated in the upholstery layer and arranged in air ducts configured to penetrate the upholstery layer from underneath the body contact area of the upholstery layer facing the ventilation layer the air ducts are so distributed in the upholstery layer to cause a uniform, area-wide ventilation of the ventilation layer which is as uniform as possible, and the ventilation layer material constructed and positioned over the air ducts to achieve deflection of the air and maintain flow of the air along a length of and transversely through the ventilation layer.
