ABSTRACT:
A method of making a seat component including the steps of sewing marginal edges of a plurality of cover material pieces with a plastic strip disposed between exterior surfaces of the marginal edges in a configuration coincident with a elongated sharply concave styling character line to form a seam in which a line of stitches extends through the marginal edges of the cover material pieces and a reduced thickness central portion of the strip along a severance line thereon or slightly outwardly thereof, applying a tape of imperforate material along the interior surface of the seam, positioning a sewn and taped panel of the cover pieces so that the exterior surface thereof is in facing relation to mold face of mold member, inserting an exterior edge portion of the strip into an elongated slot in the mold surface so as to accurately locate the seam of the panel along the elongated sharply convex styling character line, foaming a foamable material so as to adhere a body of foamed material to the interior surface of the panel while the exterior surface is held by vacuum in conformity with the mold surface, removing the panel and then removing the exterior edge portion of strip along the severance line thereof from the panel, a seat formed with one or more such components.
