Vehicle seat

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.

         9 . A vehicle seat, comprising a backrest having a backrest cushion with a ventilation layer through which air can flood, and at least one first ventilator for ventilating the cushion by sucking up air from the rear side of the backrest cushion and blowing it into the ventilation layer, wherein the ventilation layer is divided into a lower section and an upper section by an air barrier running in a transverse direction of the seat, the at least one first ventilator being assigned to the lower section and at least one second ventilator is assigned to the upper section and operating in an air-conveying direction opposite to an air-conveying direction of the at least one first ventilator. 
     
     
         10 . The vehicle seat as claimed in  claim 9 , wherein backrest cushion has a cushion pad in which at least one upper air duct is provided in the region of the upper section and at least one lower air duct is provided in the region of the lower section of the ventilation layer, air ducts being configured to completely penetrate the cushion pad from a rear side of the backrest cushion as far as the ventilation layer, and the at least one first and second ventilators being respectively assigned to the air ducts. 
     
     
         11 . The vehicle seat as claimed in  claim 10 , wherein the at least one first and second ventilators are operatively arranged in the air ducts.

         13 . The vehicle seat as claimed in  claim 12 , wherein the at least one first and second ventilators are operatively arranged in the air ducts. 
     
     
         14 . The vehicle seat as claimed in  10 , wherein the cushion pad is composed of a rubberized hair layer and an air-blocking layer. 
     
     
         15 . The vehicle seat as claimed in  claim 14 , wherein the at least one first and second ventilators are operatively arranged in the air ducts 
     
     
         16 . The vehicle seat as claimed in  claim 15 , wherein the cushion pad is operatively fixed on a cushion support 
     
     
         17 . The vehicle seat as claimed in one of  claims 9 , wherein the backrest cushion includes a pressure-distributing layer covering the ventilation layer and an air-permeable cushion cover spanning the pressure-distributing layer. 
     
     
         18 . The vehicle seat as claimed in  claim 17 , wherein the at least one first and second ventilators are operatively arranged in the air ducts. 
     
     
         19 . The vehicle seat as claimed in  claim 18 , wherein the cushion pad is operatively fixed on a cushion support. 
     
     
         20 . The vehicle seat as claimed in  19 , wherein the cushion pad is composed of a rubberized hair layer and an air-blocking layer. 
     
     
         21 . The vehicle seat as claimed in  claim 17 , wherein the pressure-distributing layer is a perforated foam material. 
     
     
         22 . The vehicle seat as claimed in  claim 9 , wherein the ventilation layer is a pressure-resistant knitted spacer fabric. 
     
     
         23 . The vehicle seat as claimed in  claim 22 , wherein the at least one first and second ventilators are operatively arranged in the air ducts. 
     
     
         24 . The vehicle seat as claimed in  claim 23 , wherein the cushion pad is operatively fixed on a cushion support. 
     
     
         25 . The vehicle seat as claimed in  24 , wherein the cushion pad is composed of a rubberized hair layer and an air-blocking layer. 
     
     
         26 . The vehicle seat as claimed in one of  claims 25  wherein the backrest cushion includes a pressure-distributing layer covering the ventilation layer and an air-permeable cushion cover spanning the pressure-distributing layer.
