摘要

Gas generator for use in impact protection device for protecting the occupants of a vehicle has a cylindrical shape with a central part forming a gas generation chamber, in the form of a pressure chamber (10), and a filter chamber (3). The chambers are sepd. by a perforated disc or ring (50), with lugs formed on the periphery to exert sealing pressure on the gas generation chamber and to hold the filter in place. ADVANTAGE - Long-term sealing at the interface between chambers is assured.
