Abstract: An automotive seat assembly comprising a trim cover material having a top surface and a bottom surface with a peripheral edge portion extending along one side thereof. A continuous stitching material passes through and between a number of apertures along the trim cover to form a first seam along the top surface and a second seam along the bottom surface. A drawstring cord is overlaid along the top surface of the trim cover between the first seam and the edge portion. The stitching material loops around a continuous first enclosure material to pull the first enclosure material against the cord and the top surface of the trim cover. Similarly, the stitching material loops around the second enclosure material to pull the second enclosure material against the bottom surface of the trim cover.

Abstract: An automotive seat assembly comprising a multitude of trim pieces sewn together along their respective edge portions. A continuous first stitching material passes through and between a number of apertures along a trim piece to form a first seam. A continuous second stitching material passes through and between a number of apertures along another trim piece to form a second seam. The first stitching material loops around the second stitching material between the trim pieces to secure the two trim pieces together. A plurality of interwoven first strands form a first cover material and a plurality of interwoven second strands form a second cover material. The first stitching material loops around the interwoven first strands to pull the first cover material against the first seam and cover the apertures in the trim piece. The second stitching material loops around the interwoven second strands to pull the second cover material against the second seam and cover the apertures in the other trim piece.
