Claim 24:
25. A method of forming a 3-dimensional ventilated trim cover for a vehicle seat, said method comprising:
forming a stacked assembly of an upper textile layer, an air permeable thermo-moldable foam interlayer, a first thermoplastic polyurethane (TPU) film, and a scrim backing layer, said air permeable thermo-moldable foam interlayer compression moldable with a compressive force in a range of about 150 psi to about 250 psi and a temperature in a range of about 104° C. to about 127° C., said upper textile layer comprising one or more of a fabric, perforated vinyl, and/or perforated leather, said scrim backing layer comprising a woven or non-woven textile, and said first TPU film including at least one air passageway through said first TPU film;
placing said stacked assembly between a lower 3-dimensional mold tool and an upper 3-dimensional mold tool;
lowering said upper 3-dimensional mold tool towards said lower 3-dimensional mold tool and applying compressive pressure in a range of about 150 psi and 250 psi on said stacked assembly to compression mold said stacked assembly;
heating at least a portion of one or more of said mold tools to a temperature range of about 65° C. to about 160° C. for about 90 seconds to about 10 minutes to form said 3-dimensional ventilated trim cover from said stacked assembly;
removing said upper 3-dimensional mold tool from said formed 3-dimensional ventilated trim cover; and
removing said formed 3-dimensional trim cover from said lower 3-dimensional mold tool.
