       20 . The ventilated seat of  claim 19 , wherein the length of the plurality of adjusting devices extends along a width of the body support device that is perpendicular to an expected position of a user's spinal column.  
   
   
       21 . The ventilated seat of  claim 19 , wherein the width of the plurality of adjusting devices is greater at end portions of the plurality of adjusting devices as opposed to a middle portion of the plurality of adjusting devices.  
   
   
       22 . The ventilated seat of  claim 8 , wherein the at least one adjusting device is attached to at least one fluid supply line for pneumatically inflating the inflatable bladder and the at least one fluid supply line includes a valve for controlling air flow to and from the inflatable bladders.  
   
   
       23 . The ventilated seat of  claim 8 , further comprising a heater located adjacent the air-permeable carrier layer and on a side of the air-permeable carrier layer opposite the air-guiding layer.  
   
   
       24 . A ventilated seat comprising: 
 a body support device for a vehicle seat;    an air-permeable carrier layer located over the body support device,    an air-guiding layer located between the air-permeable carrier layer and the body support device, wherein the air-guiding layer is located in a recess formed in the body support device and directly attached to the air feeding device and wherein the air-guiding layer is configured to receive air from an air-feeding device and guide the air through the air-permeable carrier layer; and    at least one adjusting device located between the air-guiding layer and the body support device, the at least one adjusting device including an inflatable bladder to deflect the ventilation device away, towards, or both away and towards the body support device.    
   
   
       25 . The ventilated seat of  claim 24 , wherein the air-guiding layer includes an air-impermeable material comprising a polyurethane film.
