Abstract: Method for analyzing a crash event. The method may comprise receiving an acceleration of a vehicle over a predetermined length of time, the vehicle involved in the crash event, determining a change in velocity of the vehicle based on the acceleration, determining vehicle information relating to the vehicle involved in the crash event, and estimating a damage cost for the vehicle involved in the crash event, and/or estimating injuries to occupant(s) of the vehicle involved in the crash event. Estimating damage cost(s) may include determining crash force information for the vehicle, determining physical-damage characteristics of the vehicle subsequent to the crash event, and calculating the estimated damage cost to the vehicle. Estimating injuries to the occupant(s) may include determining occupant information relating to the occupant of the vehicle, calculating estimated forces exerted on the occupant, and calculating an injury probability for various body portions for the occupant.

Abstract: A method includes the step providing an inflatable vehicle occupant protection device (14) between the side structure (16) of a vehicle (12) and a vehicle occupant (74). A thickness of the protection device (14) is determined by measuring between overlying points on overlying panels (40 and 42) of the protection device at location where an occupant's head having a given mass may contact the device. A pressure is determined as a predetermined function of the thickness of the protection device (14) and of a velocity at which the head may impact the protection device. The pressure has a magnitude sufficient to prevent a head having a given mass from striking the side structure (16) through the thickness of the protection device (14) when the head impacts the protection device at and below the velocity. An inflation fluid source (24) is provided to inflate the protection device (14) to at least the determined pressure.
