Airbag filling arrangement
First Claim
1. An arrangement for filling a flexible container essentially instantaneously with a gas mixture upon the occurrence of powerful retardation forces, wherein the container upon being filled with the gas mixture functions as a force-absorbing cushion for protection against injury, and wherein the arrangement includesa high-pressure vessel containing a gas mixture consisting essentially of hydrogen and helium,a conduit which connects the pressure vessel to the container,a mechanical opening device for opening the connection between the vessel and the container upon the occurrence of a retardation force which exceeds a smallest value, anda retardation meter, and wherein the gas mixture which fills the flexible container consists essentially of helium and hydrogen.

Abstract
The present invention relates to an arrangement for filling a flexible container with gas essentially instantaneously upon the occurrence of powerful retardation forces, wherein the gas-filled container functions as a force-absorbing cushion for protection against injury. The arrangement includes a gas-filled high-pressure vessel, a conduit which connects the pressure vessel to the container, a mechanical opening device for opening the connection between the vessel and the container upon the occurrence of a retardation force which exceeds a smallest value, and a retardation meter. The arrangement is characterized in that the vessel is filled with a gas which exhibits a reversed Joule-Thomson effect.
