ABSTRACT:
An inflatable vehicle occupant restraint (10) includes a first panel (44) of woven fabric, a second panel (40) of woven fabric, and a seam (52) at which the first and second panels (44, 40) are fastened to each other. The seam (52) includes a folded part (80) of the first panel (44) and a folded part (70) of the second panel (40). The folded part (80) of the first panel (44) includes two lapped plies (82, 84) of the first panel (44). The folded part (70) of the second panel (40) includes two lapped plies (72, 74) of the second panel (40). The folded parts (80, 70) of the first and second panels (44, 40) overlap each other so as to define a double-lapped part (89) of the seam (52) which includes four lapped plies (82, 84, 72, 74) of the first and second panels (44, 40). A first row ( 94) of stitches fastens the four lapped plies (82, 84, 72, 74) of the first and second panels (44, 40) to each other. A second row (90) of stitches is spaced from the double-lapped part (89) of the seam (52) and fastens the two lapped plies (82, 84) of the first panel (44) to each other.
