VARIABLE INFLATION SYSTEM FOR VEHICLE SAFETY RESTRAINT

摘要

An inflation system (10) for a gas-operated vehicle occupant safety restraint, such as an air bag (12), comprises an accelerometer (14) and an infrared transceiver (20) for receiving vehicle acceleration information (a) and occupant position information (x), respectively, for use by a processor (22) in selecting which of a plurality of gas generators (28) will be individually initiated, at selected actual times to fire, in a selected order, to provide optimal protection to the occupant in the event of a vehicle crash or marked vehicle deceleration.
