Abstract

A vehicle seat assembly includes a seat back with a seat back foam cushion therein having front and rear surfaces. The seat back foam cushion includes a plurality of air channels formed therethrough from the front to rear surface. A lower seat includes a lower foam cushion therein having top and bottom surfaces. The lower foam cushion includes a plurality of air holes formed therethrough from the top to the bottom surface. A porous trim cover is positioned over the seat back foam cushion and lower foam cushion. A first impeller is positioned in fluid communication with the plurality of air channels for creating a vacuum for drawing heat and moisture away from the trim cover material. Similarly, a second impeller is positioned in fluid communication with the plurality of air holes in the lower foam cushion for creating a vacuum for drawing heat and moisture away from the trim cover material. A porous cushion member is provided within the seat back foam cushion and lower foam cushion for allowing air to flow therethrough while providing cushioning support for the vehicle occupant.
