Vehicle seat with cooling/heating device

Abstract

Disclosed herein is a vehicle seat with a cooling/heating device. The vehicle seat comprises electric fans respectively equipped in a lower portion of a seat cushion and a rear portion of a seat back to intake indoor air within the vehicle, cushion members respectively provided in the seat cushion and the seat back and formed with air-supply pathways to supply air induced from the seat cushion and the seat back to an upper portion of the seat cushion and to a front portion of the seat back, air-spreading layers respectively layered on an upper portion of the cushion member provided in the seat cushion and on a front portion of the cushion member provided in the seat back to spread air induced through each of the air-supply pathways, heating pads respectively layered on the air-spreading layers, with a heating line disposed therein, and with a plurality of ventilation holes punctured through each of the heating pads between serpentine sections of the heating line along the heating line, and seat covers respectively layered on the heating pads and having a plurality of air discharge openings formed on the surface of the seat cover.

1 . A vehicle seat including a seat cushion and a seat back with a cooling/heating device, the vehicle seat comprising: 
 electric fans respectively equipped in a lower portion of the seat cushion and a rear portion of the seat back to intake indoor air within a vehicle into the seat cushion and the seat back;    cushion members respectively provided in the seat cushion and the seat back and formed with air-supply pathways to supply air induced from the seat cushion and the seat back to an upper portion of the seat cushion and to a front portion of the seat back;    air-spreading layers respectively layered on an upper portion of the cushion member provided in the seat cushion and on a front portion of the cushion member provided in the seat back to spread air induced through the air-supply pathways by an area corresponding to at least an area of the vehicle seat contacting the hip and the back of a person seated in the vehicle;    heating pads respectively layered on the air-spreading layers, with a heating line disposed therein to generate heat when electric power is applied to the heating line, and with a plurality of ventilation holes punctured through each of the heating pads between serpentine sections of the heating line along the heating line; and    seat covers respectively layered on the heating pads and having a plurality of air discharge openings formed on the surface of each of the seat covers, through which air supplied through the air-spreading layers and the ventilation holes of the heating pads is discharged.    
   
   
       2 . The vehicle seat as set forth in  claim 1 , wherein the electric fans are equipped at the left and right sides of the front side of the lower portion of the seat cushion and at the left and right sides of the rear side of the upper portion of the seat back, respectively, and are controlled to have at least two speeds according to variable speed control by a control switch.  
   
   
       3 . The vehicle seat as set forth in  claim 1 , wherein each of the air-spreading layer comprises hexagonal-shaped upper and lower nets with synthetic resin yarns connected between the upper and lower nets in a serpentine shape to provide air permeability and elasticity.  
   
   
       4 . The vehicle seat as set forth in  claim 1 , wherein the heating line of each of the heating pads is controlled to have at least two temperature levels according to variable temperature control by a control switch.  
   
   
       5 . The vehicle seat as set forth in  claim 1 , wherein a sealing pad is provided between each of the cushion members and each of the air-spreading layers, and has apertures at positions corresponding to the air-supply pathways.  
   
   
       6 . The vehicle seat as set forth in  claim 1 , wherein a porous spongy member is positioned between each of the heating pads and each of the seat covers.  
   
   
       7 . A vehicle seat including a seat cushion and a seat back with a cooling/heating device, the vehicle seat comprising: 
 electric fans respectively equipped in a lower portion of the seat cushion and a rear portion of the seat back to intake indoor air within a vehicle into the seat cushion and the seat back;    cushion members respectively provided in the seat cushion and the seat back and formed with air-supply pathways to supply air induced from the seat cushion and the seat back to an upper portion of the seat cushion and to a front portion of the seat back;    air-spreading layers respectively layered on an upper portion of the cushion member provided in the seat cushion and on a front portion of the cushion member provided in the seat back to spread air induced through each of the air-supply pathways by an area corresponding to at least an area of the vehicle seat contacting the hip and the back of a person seated in the vehicle;    heating pads respectively layered on the air-spreading layers, with a heating line disposed therein to generate heat when electric power is applied to the heating line, and with a plurality of ventilation holes punctured through each of the heating pads between serpentine sections of the heating line along the heating line;    seat covers respectively layered on the heating pads and having a plurality of air discharge openings formed on the surface of each of the seat covers, through which air supplied through the air-spreading layers and the ventilation holes of the heating pads is discharged;    an air contamination-detecting sensor to detect a contaminated state of air within the vehicle;    an anion generator to generate anions by applying a high voltage from a high voltage generating part to an anion generating part consisting of a brush-shaped conductive bundle of fibers; and    a controller having an anion generator driving circuit to drive the high voltage generating part when signal data detected by the air contamination-detecting sensor has a value higher than that of reference data previously stored in a memory after comparing the signal data with the reference data.    
   
   
       8 . The vehicle seat as set forth in  claim 7 , wherein the anion generating part is equipped to the air-supply pathway.  
   
   
       9 . The vehicle seat as set forth in  claim 7 , wherein the air contamination-detecting sensor is equipped in a space between the seat and a floor of the vehicle.
