Automotive vehicle seat and blower module for such an automotive vehicle seat

Abstract

An automotive vehicle seat for accommodating a blower module, wherein the automotive vehicle seat is designed as a “unitary seat” and comprises all necessary components in an already prefabricated state for supplying hot or cold air to the seat so as to equip or retrofit said seat in case of need with the blower module.

We claim:  
     
         1 . An automotive vehicle seat comprising: a seat cushion part including a substantially horizontal seat surface, and a backrest substantially perpendicular thereto, said seat cushion part and said backrest comprising an air-permeable, breathable surface cover facing the body to be accommodated, wherein 
 said surface cover has disposed thereunder a knitwear which comprises an air-permeable cover layer, a base layer and a multitude of spacers which connect said two layers and keep them spaced apart to let the air, which has been blown into said knitwear at a desired location, exit out of said surface cover, the air being distributed as uniformly as possible over the whole area,    said knitwear has arranged therebehind or thereunder a support body which preferably consists of a plastic foam and has formed therein air flow channels which at the inlet side terminate in a chamber and at the outlet side into said knitwear, said channels being open over their whole lengths, and wherein    and, said chamber is formed by a recess formed in said support body to accommodate a blower module in said chamber.    
     
     
         2 . A blower module for use in an automotive vehicle seat according to  claim 1 , characterized by 
 an air intake opening,    at least one blow-out opening,    a radial blower which at the inlet side communicates with said air intake opening,    a heat register comprising electric heat resistors,    an electronic controller,    one temperature sensor each arranged in the intake tract and the blow-out tract, respectively, which are connected as actual value sensors to said electronic controller, and wherein 
 said units are constructionally arranged side by side in one plane.  
   
     
     
         3 . An automotive vehicle seat comprising: 
 a seat cushion part including a substantially horizontal seat surface, and    a backrest substantially perpendicular thereto, said seat cushion part and said backrest comprising 
 an air-permeable, breathable surface cover configured to face a person's body when the person is seated on the seat,  
 a knitwear which is located under said surface cover and which comprises an air-permeable cover layer, a base layer, and a plurality of spacers which interconnect said cover layer and said base layer and which maintain a spacing therebetween to let air, blown into said knitwear, exit out of said surface cover, the air being distributable at least generally uniformly over an entire surface area of the surface cover,  
 a support body which is located at least one of under and behind said knitwear and which is formed at least in part from a plastic foam having formed therein air flow channels, said air flow channels having an inlet side which terminates in a chamber and an outlet side opening into said knitwear, said air flow channels being open over entire lengths thereof, said chamber being formed by a recess in said support body and being configured to accommodate a blower module.  
   
     
     
         4 . The automotive seat according to  claim 3 , further comprising a blower module including 
 at least one intake tract terminating at an air intake opening,    at least one blow-out tract terminating a blow-out opening,    a radial blower which having an inlet side which communicates with said air intake opening,    a heat register comprising electric heat resistors,    an electronic controller, and    temperature sensors which are arranged in said intake tract and said blow-out tract, respectively, and which are electronically connected to said electronic controller, wherein said blower, said heat resistors, said electronic controller, and said temperature sensors are constructionally arranged side by side in one plane.
