Abstract
A seat trim cover for an automotive seat is formed into a 3-dimensional shape by compression molding a laminated moldable foam in a 3-dimensional. The laminated moldable foam comprises at least a layer of cellular polyurethane foam compression moldable in a temperature range of about 220° F. to about 260° F. The 3-dimensional mold is heated to a temperature range of about 150° F. to about 320° F. The layer of cellular foam is adhered to a cover material layer and pre-cut into a pre-laminated blank prior to molding into the 3-dimensional shape. Optionally, seat heaters or other components can be integrated with the laminated foam prior to compression molding the seat trim cover.
