Gas generator for vehicle airbags etc. has compressed gas chamber divided into main, auxiliary chambers connected via openings closed by elements adaptively opened to set outlet gas volumetric flow

摘要

The device has a generation chamber(s), an outflow chamber, a chamber(s) holding compressed gas and controlled devices for opening connections between the gas generation or compressed gas chamber and the outflow chamber. The compressed gas chamber is divided into a main chamber and at least one auxiliary chamber for connection via connection openings closed by closure elements that are adaptively opened to set the outlet gas volumetric flow. The device has at least one gas generation chamber (12), an outflow chamber (14), at least one chamber (24) holding compressed gas and opening devices for opening the connections between the gas generation chamber or compressed gas chamber and the outflow chamber in a controlled manner. The compressed gas chamber is divided into a main chamber (26) and at least one auxiliary chamber (28) for connection via connection openings closed by closure elements (34) that are adaptively opened to set the outlet gas volumetric flow.
