Gas generator used with vehicle safety equipment, e.g. safety belt tighteners and airbags, includes resilient connection between casings forming pressure-dependent flow opening

摘要

A resilient component (58) intervenes between the second and third casings (34, 36). In the initial state, this secures the second casing to the cover (38). In the operational state, movement of the second casing relative to the first (32), forms an opening (46) for flow. Its cross section is pressure-dependent.
