Abstract: The implementation of dual-stage inflators in some production vehicles is quickly becoming a common reality. A dual-stage inflator has two firing squibs that can fire independently, simultaneously or in a delayed mode. This tailorability provides the ability to fire a low level, high level or staged delay level depending on the impact velocity or other means. For each restraint condition, the inflator output threshold speeds are identified. A biomechanical gray zone, for each injury assessment reference value, is defined based on occupant performance. The upper and lower bound of each biomechanical gray zone is associated with a type of occupant, inflator output, belt restraint and injury parameter.

The surface comprises a top portion and two side portions (8) on either side of the top portion, and the top portion and at least one of the side portions are shaped so as to present a countered surface to the seat belt webbing. Preferably, the central area (7) of the top portion is raised, and the central area (9) of one or both side portions (8), is recessed, but the opposite contour arrangement could be provided with the central area of the top portion recessed and the central area of one or both side portions raised.

Abstract: A safety apparatus including an air bag (20). The air bag includes a first (22) and second (24) panel of flexible, impermeable material, each panel having a respective peripheral edge (23,25). The first and second panels are joined together along a structural first joint (110), which extends along a substantial portion of the peripheral edges to define an inflatable chamber (26) therebetween. The first joint (110) is subject to a peel load as the first and second panels are urged apart as the chamber is inflated. The apparatus also includes inlet means (32, 44) for communicating inflation gas into the chamber. A pressure barrier (100) is located within the chamber, for preventing inflation gas from bearing against the first joint. In the preferred embodiment, the pressure barrier is not subject to the peel load as is the first joint.

Abstract: A force sensor (50, 50′, 50a) generates a signal indicating the usage of a seat belt. A cylindrical housing (70, 70′) has a wall (72) and a bottom (74) which define an internal cavity (124). The bottom has an opening (76) through it. A cable anchor (90) is slidably received within the cavity and is connected to a cable (54). The cable has one end secured to the cable anchor and another end connected to an anchor point. A magnet (120) is connected to a top of the cable anchor and is movable with the cable anchor. The cable anchor is biased to resist motion of the cable anchor toward the bottom of the housing. A magnetic sensor (200) for generates a signal indicative of the distance between it and the magnet. A sensor housing (180) is connected to the housing and is positioned on the housing to position the magnetic sensor a determinable distance from the magnet at a null position. A housing end cap (150) is secured to the housing for enclosing an open end of the housing.

The wedge(22) is preferably integral with the housing cover (8). This housing makes fitting of the gas generator easier and improves the seal between it and the pretensioner thus improving performance.

Abstract: A vehicle occupant safety device (20) comprising: an air bag (70) initially in a folded configuration and when inflated by inflation gases expands to an inflated configuration to protect the occupant; an inflator (50) for providing inflation gases to inflate the air bag; a shroud (80) comprising a plurality of frangible straps, preferably loosely positioned about the exterior of the folded air bag for controlling the trajectory of the inflating air bag by initially restricting the forward extension of the air bag by interaction with the shroud (80) and thereafter directing the air bag to inflate along a passageway defined by the shroud which is oriented at a downward angle relative to the occupant. Once the air bag exits the shroud it is free to inflate laterally and upwardly to protect the occupant. In one embodiment the shroud includes a tearable strap (140).
