ABSTRACT:
The present invention relates to a system for filling an empty flexible container such as an airbag with gas essentially instantaneously when the system or vehicle utilizing such system is subjected to sufficient deceleration forces, such as experienced during a collision. The gas-filled container functions as a force absorbing cushion which protects occupants in the vehicle against injuries. The system includes pressure vessels filled with gas under high pressure, one or more conduits connecting the pressure vessels with the flexible container, provisions for opening the connection between the pressure vessels and the flexible container upon sensing retardation or deceleration forces that exceed some threshold value, a container holding or mixing device, and a retardation meter. The pressure vessels are each sealed by a closure device and each has a respective connection conduit which joins the pressure vessels to the flexible container. One pressure vessel contains oxygen and an inert gas. The other pressure vessel contains inert gas and hydrogen. The inert gas is helium, argon and/or nitrogen.
