ABSTRACT:
A method for making a portion of a vehicle seat or back having a surface contour of predetermined shape by placing a sheet of an impermeable film against one side of a portion of a sheet of a permeable cloth fabric to make an impermeable composite portion of a fabric trim material. The composite portion is then positioned on a forming tool having a shaped upper surface complementary to the predetermined shape desired for the final product. A vacuum is then drawn between the forming tool and the impermeable composite portion so as to draw the portion into conformity with the shaped upper surface of the forming tool. A foam bun having an adhesive coated surface is then positioned against the portion on the forming tool. Heat is then applied to deteriorate the impermeable film thus enabling the adhesive to bond the cloth fabric material to the foam bun and maintain the desired shape.
