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.
