Abstract

A gas generator includes an ignition charge, at least one ignition element for igniting the ignition charge, a storage chamber containing a compressed gas, which storage chamber is closed by a closure element, and an impact element destroying the closure element under pressure. A piston is provided as the impact element, which piston, after the destruction of the closure element, forms an exit gap with the opening closed by the closure element. The cross-sectional area of which exit gap changes in according to the position of the piston.
