Abstract: A restraining device is described incorporating an inflatable bag positioned in a vehicle to restrain persons in a vehicle and prevent them from colliding with objects when the vehicle is subjected to collision accelerations. The bag incorporates passageways therein which are connected to a gas source; the gas source, when actuated, inflates the passageways, thus extending the bag and drawing air into the bag from the atmosphere within the vehicle. A unidirectional valve permits the air to enter the bag, but prevents its escape in the event the pressure within the bag exceeds that of the atmosphere within the vehicle, such as by the impact of a person with the bag.
