System for inflating a vehicular gas bag (10) with gas from a bottle of compressed gas (12) against an occupant (13) in an emergency include a gas pressure sensor (39) having a sensor input (20) coupled to compressed gas in the bottle prior to an emergency, and having a sensed pressure output (21).

System for inflating a vehicular gas bag (10) with gas from a bottle of compressed gas (12) against an occupant (13) in an emergency include a gas pressure sensor (39) having a sensor input (20) coupled to compressed gas in the bottle prior to an emergency, and having 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 and inverse to the variable gas inlet passage (see 37 vs. 34), and having a gas venting passage variator (23) coupled to the sensed pressure output. A compressed gas release (25) having a compressed gas outlet (26) on the bottle is connected to the gas inlet passage (15) and to the variable gas venting passage (16). The gas pressure sensor (21) may be temperature-compensated (46-48). Gas discharge from the bottle (12) to the bag (10) may be shaped, such as with the aid of a temporary compressed gas flow restriction (52, 54, 55), for a more controlled gas discharge from the bottle or for a more gentle inflation of the gas bag.
