A dual-stage inflator (52, 54) has squibs (48, 50) that can fire independently, simultaneously or in a delayed mode. This flexibility provide s the ability to fire a low level, high level or staged delay level depending on the impact velocity or other parameters. For each restraint condition, the inflator output threshold speeds are identified. A biomechanical gray zone f or each injury assessment reference value is defined based on vehicle occupant performance. The upper and lower bounds of each biomechanical gray zone are associated with a type of vehicle occupant, inflator output, belt restraint and injury parameter. |
