Abstract
An air bag (10) comprises an adhesive material (60) located between and interconnecting first and second panels (40, 50). A stitching section (70) extends through the first panel (40) and through the adhesive material (60) and through the second panel (50) to block relative movement between the first and second panels. The adhesive material resists separation of the yarns (56, 58) of the panels (40, 50). The adhesive material (60) also fills thread openings (94) in the second panel (50) around the stitching section (70).
