Abstract:
An apparatus (10) for helping to protect an occupant (20) of a vehicle (12) includes an inflatable vehicle occupant protection device (14) having a deflated condition and an inflated condition. Tear stitching (200a) interconnects portions (220a, 230a) of the protection device (14). The tear stitching (200a) includes first and second stitch lines (300, 320) positioned next to each other. The first stitch line (300) is adapted to rupture in response to tension of a first magnitude exerted on the interconnected portions (220a, 230a) while inflating to an initially deployed condition. The second stitch line (320) is adapted to remain intact and being capable itself of maintaining the protection device in the initially deployed condition subsequent to rupture of the first stitch line (300) and throughout inflation and deployment of the protection device (14).
