Ventilated vehicle seat assembly

A vehicle seat assembly, comprising:

• a seat back including a seat back foam cushion therein having front and rear surfaces, said seat back foam cushion having a plurality of air channels formed therethrough from the front to rear surface;
• a porous trim cover material positioned adjacent the front surface of the seat back foam cushion;
• a rear flow channel formed along said rear surface in fluid communication with said plurality of air channels, wherein said rear flow channel comprises a porous cushion member through which air flows while the porous cushion member cushions a vehicle occupant;
• means for moving air through the porous cushion member for moving heat and moisture away from the porous trim cover material, said means for moving air comprising a first impeller positioned in fluid communication with said rear flow channel for creating a vacuum for drawing heat and moisture away from said trim cover material;
• a lower seat including a lower foam cushion therein having top and bottom surfaces, said lower foam cushion having a plurality of air holes formed therethrough from the top to the bottom surface;
• a bottom flow channel formed along said bottom surface in fluid communication with said plurality of air holes, wherein said bottom flow channel comprises a porous cushion member through which air flows while the porous cushion member cushions the vehicle occupant;
• and
• means for moving air through the bottom flow channel comprising a second impeller positioned in fluid communication with said bottom flow channel for drawing heat and moisture away from the trim cover material.
