An airbag (10) has a first tier of material (11) and a second tier of material (12). The second tier (12) at least partially overlaps the first tier (11). The first and second tiers (11, 12) are joined together by one or more rows of a sealed stitch seam (20). The sealed stitch seam (20) has a plurality of thread stitches (30) extending from one exterior side (14) through to the opposite exterior side (16) of the at least partially overlapped first and second tiers (11, 12). The thread stitches (30) are coated in each exterior side (14, 16) with a seam coating material (40). The seam coating material (40) is either applied over the stitches (30) on one exterior side (14 or 16) and flows through to the opposite side (14 or 16) through thread holes (52) formed upon the creation of the seam (20) or is applied to both exterior sides (14, 16) and flows into the thread holes (52) to encapsulate and seal the seam (20). |
