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).

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 (200) interconnects portions (220 and 230) of the protection device (14) and is rupturable to permit the interconnected portions to move relative to each other. The tear stitching (200) includes a break point (210) and first and second segments (212) that extend away from the break point. The tear stitching (200) is arranged on the protection device (14) such that tension forces acting to rupture the tear stitching act primarily on the break point (210) so that the tear stitching ruptures first at the break point and then along the first and second segments (212) of the tear stitching.

Abstract: An apparatus (10) includes an inflatable vehicle occupant protection device (14) that includes a first panel (160) with at least one first vent opening (142). A second panel (144) secured to the first panel (160) includes a base portion (150) and a door portion (156). The base portion (150) includes at least one second vent opening (200) and is folded to position the door portion (156) between the first panel (160) and the base portion (150). The door portion (156) has an open condition positioned away from the vent openings (142, 200) permitting inflation fluid to vent through the vent openings. The door portion (156) has a closed condition positioned between the first and second vent openings (142, 200) blocking inflation fluid from venting through the first and second vent openings. The door portion (156) is movable to the closed condition when the protection device (14) deploys.

Abstract: An apparatus (10) for helping to protect an occupant (20) of a vehicle (12) includes an inflatable vehicle occupant protection device (14) inflatable from a stored condition to a deployed condition in which the protection device is positioned between an instrument panel (36) of the vehicle and the vehicle occupant. The protection device (14) includes upper portion (142) and a lower portion (144), each of which is at least one of rolled and folded. The upper portion (142) and the lower portion (144) are positioned overlying each other when in the stored condition. A deployment flap (120) includes a sheet of material having a first end portion (130) secured to the vehicle. The deployment flap (120) has a central portion (134) that wraps around the lower portion (144) and a second end portion (132), opposite the first end portion (130), that is tucked under the lower portion while the protection device (14) is in the stored condition.

Abstract: An apparatus for helping to protect an occupant (15 or 16) of a vehicle (17) includes an inflatable vehicle occupant protection device (10) and an inflation fluid source. The inflatable vehicle occupant protection device (10) has a stored, deflated position and an inflated position. The inflation fluid source provides inflation fluid to inflate the inflatable vehicle occupant protection device (10). The inflatable vehicle occupant protection device (10) has a first panel portion (501) for, when the inflatable vehicle occupant protection device (10) is inflated, protecting an adult size vehicle occupant (15). The inflatable vehicle occupant protection device (10) has a second panel portion (502) for, when the inflatable vehicle occupant protection device (10) is inflated, defining a downwardly open pocket (520) for receiving a portion of a child size vehicle occupant (16).
