Claim 13:
14. A ventilated vehicle seat, said ventilated vehicle seat comprising:
a foam base pad including an air channel passing through at least a portion of said foam base pad;
a fan fluidically connected to said air channel and configured for directing airflow through said air channel;
a ventilated seat trim cover formed by compression-molding an upper textile layer of one or more of a fabric, perforated vinyl, and/or perforated leather, an air permeable thermo-moldable polyurethane cellular foam interlayer formulated to be thermo-moldable between about 104° C. and about 127° C., a first thermoplastic polyurethane (TPU) film, and a scrim backing layer of a woven or non-woven textile in a 3-dimensional mold at about 150 psi to about 250 psi compressive force while at least a portion of said foam interlayer is heated to a temperature of about 104° C. to about 127° C. to compression mold said foam interlayer into a 3-dimensional shape;
said first TPU film including a passageway through said first TPU film; and
said ventilated seat trim cover being assembled with said foam base pad such that said passageway in said first TPU film is fluidically coupled with said air channel;
wherein when said fan directs airflow through said air channel, airflow passes between said air channel and said foam interlayer through said passageway in said first TPU film, and airflow passes between said foam interlayer and through said upper textile layer.
