OCCUPANT-SENSITIVE VEHICULAR GAS PRESSURE RESTRAINT SYSTEMS

摘要

A system for inflating a vehicular gas bag (10) with gas from a bottle of compressed gas (12) against an occupant (13) in an emergency includes an occupant parameter sensor (17) having a sensed occupant parameter output (24), and a gas flow variator (27) coupled to such sensed occupant parameter output. A gas pressure sensor (18) has a sensor input coupled to compressed gas in the bottle (12) prior to an emergency, and has a sensed pressure output (21). A variable gas inlet passage (15) for the gas bag has a gas inlet passage variator (22) coupled to the sensed pressure output (21) and a variable gas venting passage (16) positioned in circumvention of the gas inlet passage (15) and inverse to the variable gas inlet passage (15), and has a gas venting passage variator (23) coupled to the sensed pressure output (21). A compressed gas release has a compressed gas outlet (26) on the bottle (12) coupled to the gas inlet passage (15), to the variable gas venting passage (16) and to the gas flow variator (27).
