Abstract

A cushioning for a vehicle seat has a cushioning layer and a ventilation layer which covers this cushioning layer and through which air flows. A plurality of air ducts completely penetrate the cushioning layer and are open on the backside of the cushioning layer and in which one miniature fan respectively is arranged for blowing air into the ventilation layer. For ventilating cushioning areas which, because of sitting aids arranged in the cushioning layer, are not suitable for a direct ventilation, the end of the air ducts assigned to these cushioning areas which faces the ventilation layer is constructed such that a portion of the air flow penetrating the air duct enters into the open cross-sectional surface of the ventilation layer.
