Abstract
An inflatable gas bag for a restraining system in vehicles is provided in its wall with at least one predefined relief opening which remains sealed up to a predetermined internal pressure of the gas bag and is freed only when this internal pressure is exceeded. The gas bag therefore has the desired hardness in the initial phase of the restraining operation and thereafter effects an energy absorption by controlled discharge of the gases through the relief opening.
