Method and apparatus for sewing a plurality of trim pieces together

A method of securing a first and second trim piece together utilizing continuous first and second stitching materials to form a first and second seam respectfully, and a plurality of interwoven first and second strands defining first and second cover materials, respectively, for covering each of the seams, the method comprising the steps of:

• feeding the continuous first stitching material through and between each of a plurality of apertures in the first trim piece along the first seam,
• feeding the continuous second stitching material through and between each of a plurality of apertures in the second trim piece along the second seam,
• looping the first stitching material around the second stitching material between the first and second trim pieces,
• looping the first stitching material around at least a portion of the interwoven first strands between each of the apertures along the first seam of the first trim piece,
• looping the second stitching material around at least a portion of the interwoven second strands between each of the apertures along the second seam of the second trim piece,
• pulling the first cover material against the first seam to cover the apertures in the first trim piece, and
• pulling the second cover material against the second seam to cover the apertures in the second trim piece.

A sewing machine assembly for sewing a plurality of trim pieces, said assembly comprising;

• a needle,
• a first stitching material passing through said needle,
• a moveable vibrator foot,
• a first cover material passing through said vibrator foot,
• a moveable feed dog,
• a stationary plate mounted in close proximity to said feed dog,
• a second stitching material passing through said feed dog,
• a second cover material, and
• guide members for guiding said second cover material through said feed dog.

An automotive seat assembly comprising,

• a first trim piece having a top surface and a bottom surface,
• a second trim piece having a top surface and a bottom surface,
• said first trim piece having an edge portion overlaying an edge portion of said second trim piece along said respective top surfaces,
• each of said first and second trim pieces including a plurality of spaced apart apertures extending through said respective top and bottom surfaces along said edge portions,
• a continuous first stitching material passing through and between each of said apertures along said bottom surface of said first trim piece to form a first seam,
• a plurality of interwoven first strands forming a first cover material,
• said first stitching material looping around at least a portion of said interwoven first strands to pull said first cover material against said first seam and cover said apertures in said first trim piece,
• a plurality of interwoven second strands forming a second cover material,
• said second cover material looping around said first stitching material to pull said second cover material against said bottom surface of said second trim piece to form a second seam and cover said apertures in said second trim piece.

• feeding the continuous first stitching material through and between each of a plurality of apertures in the first trim piece along the first seam,
• looping the first stitching material around at least a portion of the interwoven first strands between each of the apertures along the first seam of the first trim piece,
• pulling the first cover material against the first seam to cover the apertures in the first trim piece,
• feeding the continuous first stitching material through each of a plurality of apertures in the second trim piece along the second seam,
• looping the second cover material around the first stitching material, and
• pulling the second cover material against the second seam to cover the apertures in the second trim piece.
