Arrangement for ventilation of a vehicle seat

Abstract

The invention relates to an arrangement for ventilation of a vehicle seat, which arrangement comprises an air-distributing material and an electric heating element comprising at least one electrically conductive component arranged in a pattern in conjunction with at least one support, where the vehicle seat comprises a bottom part which is adapted for ventilation by blowing air in or sucking air out via at least one passage through the bottom part and on through the said air-distributing material. According to the invention, the said support, heating element and air-distributing material are manufactured as an integrated arrangement adapted for mounting in conjunction with the said vehicle seat, the said air-distributing material being designed as at least one unit which is dimensioned for mounting in a correspondingly designed cutout in the vehicle seat. By means of the invention, an improved arrangement for heating and ventilation of a seat in a vehicle is obtained.

1 . Arrangement for ventilation of a vehicle seat, which arrangement comprises an air-distributing material and an electric heating element comprising at least one electrically conductive component arranged in a pattern in conjunction with at least one support, where the vehicle seat comprises a bottom part which is adapted for ventilation by blowing air in or sucking air out via at least one passage through the bottom part and on through the said air-distributing material wherein the said support, heating element and air-distributing material are manufactured as an integrated arrangement adapted for mounting in conjunction with the said vehicle seat, the said air-distributing material being designed as at least one unit which is dimensioned for mounting in a correspondingly designed cutout in the vehicle seat.  
   
   
       2 . Arrangement according to  claim 1 , wherein the said support is designed as a layer of which the external dimensions exceed the dimensions of the said cutout, an edge portion of the support being defined, which overlaps a gap between the outer edge of the air-distributing material and the inner side of the cutout.  
   
   
       3 . Arrangement according to  claim 2 , wherein the said edge portion defines a seal for the said gap in order at least substantially to prevent the said air flowing through.  
   
   
       4 . Arrangement according to  claim 2 , wherein the said edge portion is designed with means for anchoring the support to the said seat.  
   
   
       5 . Arrangement according to  claim 1 , wherein the support consists of foamed polyurethane.  
   
   
       6 . Arrangement according to  claim 1 , wherein the support consists of air-distributing material.  
   
   
       7 . Arrangement according to  claim 6 , wherein the said electrically conductive component is attached between supports consisting of a first layer and a second layer of air-distributing material.  
   
   
       8 . Arrangement according to  claim 6 , wherein the said electrically conductive component is located inside a support consisting of a layer of air-distributing material.  
   
   
       9 . Arrangement according to  claim 1 , wherein it comprises an airflow-guiding material layer arranged between the said support and the said air-distributing material.  
   
   
       10 . Arrangement according to  claim 9 , wherein the said material layer consists of a glue layer of which the thickness is selected depending on the permitted air flowthrough through the said support material at the position of the said material layer.  
   
   
       11 . Arrangement according to  claim 1 , wherein it is moreover used in a back part belonging to the vehicle seat, which part is adapted for ventilation by blowing air in or sucking air out via at least one opening through the air-distributing material.
