Vehicle seat with a temperature control unit

Abstract

A vehicle seat with a temperature control unit is composed of a plurality of ditches installed on a surface of a seat pad covered with the second plate having a vent and a divergence department on a surface of a seat pad covered with the first plate, wherein the presence of a plurality of ditches on a surface of a seat pad and a divergence department to diverge a heated or cooled air sent from a blower to each ditch give good ventilation of a heated or cooled air.

1 . A vehicle seat with a temperature control unit comprising:
 a plurality of ditches on a surface of a seat pad;   a blower to send a heated or cooled air to the surface of said seat pad;   a divergence department to diverge an air sent from the blower into said plurality of ditches;   a first plate having non-breathability to cover the surface of a seat pad in said divergence department;   a second plate having non-breathability to cover the surface of a seat pad in said plurality of ditches; and   the second plate partially having a vent making it possible to discharge an air from said plurality of ditches.   
   
   
       2 . The vehicle seat with the temperature control unit of  claim 1  wherein the first plate and the second plate having flexibility. 
   
   
       3 . The vehicle seat with the temperature control unit of  claim 1  wherein the first plate and the second plate are fixed on said seat pad with an adhesive. 
   
   
       4 . The vehicle seat with the temperature control unit of  claim 1  wherein the first plate and the second plate are formed in one body. 
   
   
       5 . The vehicle seat with the temperature control unit of  claim 1  wherein a film-shaped occupant detecting sensor is installed on a surface of the first plate or the second plate.
