Abstract: A vehicle seat, in particular a rear seat, has a backrest with a backrest cushion having a ventilation layer through which air can flood, and with at least one ventilator for ventilating the cushion. The ventilator sucks up air from the rear space of the backrest cushion and blows it into the ventilation layer. The ventilation layer is divided into a lower and upper section by an air barrier running in the transverse direction of the seat. At least one ventilator is assigned to the lower section of the ventilation layer and at least one further ventilator with an air-conveying direction the other way around with respect to the air-conveying direction of the first ventilator is assigned to the upper section of the ventilation layer.

Abstract: A vehicle seat for a motor vehicle has a cushion core and ventilation ducts which run along and inside a seat surface and/or backrest surface, and each have a constant cross section ventilation channels are essentially arranged transversely to the ventilation ducts, have a constant cross section, penetrate the entire thickness of the cushion core and extend from the ventilation ducts as far as a rear wall facing away from the seat surface and/or backrest surface. A predetermined arrangement of the ventilation ducts and/or ventilation channels defines regions in the cushion core which are ventilated to different extents and are adapted to a ventilation requirement of a standard vehicle occupant.

Abstract: A series of components is provided for a vehicle seat of a motor vehicle. Each vehicle seat has a cushion core with ventilation ducts running along and inside a seat surface and/or backrest surface. Ventilation channels are arranged essentially transversely to the ventilation ducts, penetrate the entire thickness of the cushion core and extend from the ventilation ducts as far as a rear wall facing away from the seat surface and/or backrest surface. For a passively ventilated vehicle seat, the ventilation channels are connected in a flow-permeable manner to the surroundings via an opening in the ear wall, whereas, in an actively ventilated vehicle seat, at least one fan is provided and at least one ventilation channel is closed.

Abstract: A motor vehicle seat includes padding which is assigned to a backrest or a seat cushion and includes a lower padding part, a ventilation layer which rests on the lower padding part and through which air may flow, and an air-permeable, upper padding layer arranged above the latter, the padding covered by upholstery and provided with stitching along which the upholstery is connected to the upper padding layer via fastening device(s), and the ventilation layer extending into side parts of the padding and having a virtually unchanged thickness in the region of the stitching. The upholstery and the upper padding layer are fastened to the lower padding part along the stitching via the fastening device(s) bridging the ventilation layer.

Abstract: In a motor vehicle seat having a backrest, the padding of which includes a ventilation layer through which air can flow with the aid of a fan of a ventilation device, the backrest provided on its rear side with a soft trim part from which at least one air inlet opening for the ventilation device has been left open. The air inlet opening is arranged in the upper region of the soft trim part of the backrest and in the region of overlap with the associated fan of the ventilation device, the air inlet opening covered by a covering arranged on the soft trim part.
