Abstract
A gas bag protection device comprises a gas bag which has an outer wall made of a first material. The outer wall has at least one outflow opening. A membrane made of an extensible, second material is provided which is fastened to the outer wall and covers the outflow opening in the not fully inflated state of the gas bag. The gas bag protection device further comprises a device provided outside the gas bag and serving for destroying the membrane. The gas bag and the device are arranged spaced so far apart from each other that the membrane meets the device only when a predetermined internal pressure of the gas bag has been reached.
