The present invention relates to apparatus for filling an empty, flexible container (8) with gas essentially instantaneously when subjected to powerful retardation forces, wherein the gas-filled container (8) functions as a force-absorbing cushion which protects against injuries, wherein the apparatus includes pressure receptacles (1, 2) which is filled with gas under high pressure, a conduit (5) which connects the receptacles (1, 2) with the container (8), means for opening the connection between the receptacles (1, 2) and the flexible container (8) when subjected to retardation forces that exceed a smallest value, a container-holding device (7), and a retardation meter. The vessel is comprised of two pressure receptacles (1, 2) which are each sealed by means of a closure means and each of which has a respective connection conduit (3 and 4) which joins pressure receptacles (1, 2) to the flexible container (8). One pressure receptacle (1) contains oxygen and an inert gas while the other receptacle (2) contains inert gas and hydrogen, wherein the inert gas is helium, argon and/or nitrogen.

[ What is claimed is:] [1.] A method of filling an empty, flexible container to be provided in a vehicle with a gas when the container is subjected to a powerful retardation, wherein the gas-filled container functions as a force absorbing cushion which protects against injuries, said method comprising the following steps of operation:partly filling the container during a first filling step,sensing a value of a parameter reflecting the size of the container as a result of an object or a person being positioned in the expansion zone of the container, andcontinuing filling of the container during a second filling step if said value indicates that no object or person is positioned within the expansion zone of the container and not performing said second filling step if said value indicates that an object or person is positioned within the expansion zone of the container.
