    • Vehicle passenger collision protection device comprising an inflatable air bag and an acceleration sensor for determining the event of an impending accident and triggering the inflation of the air bag. The acceleration sensor is connected to the air bag inflation pyrotechnic propellant charge which expansion for the inflation of the air bag whereby the propellant is ignited by the appropriate sensor signal. The sensor activates a fan to run at its maximum power output to remove the combustion gases and particulates which escape from the air bag into the passenger space. The fan may be operated as a blower to force fresh air in or as an exhaust fan to suck contaminated air out of the passenger compartment. The fan is preferably the conventional fan associated with the air conditioning system provided in the vehicle. Alternately, a separate fan is connected to the existing ventilation system and may substitute for or supplement the first fan. In another alternative, the sensor controls the opening of electric windows and/or sunroof to assist the fan in rapid fresh air exchange between the outside ambient atmosphere and the passenger compartment. The fan(s), window(s) and/or sunroof can be started prior to the crash by setting the controller to activate them at a lower deceleration value than the pyrotechnic igniter. Auxiliary (battery) power supply means may be provided to insure fan operation in the event the car battery or electrical wiring is damaged in the crash.
