Closure system for high pressure compressed gas container of cold gas generator utilized for automotive airbag, has sealing elements sealing high pressure gas container, where annular space is formed between sealing elements and closure cap

摘要

The system has a narrow annular space formed between two annular sealing elements and a movable closure cap (8) in a resting position, where the sealing elements comprise a seat seal (6) and a lip seal (7). Radial boreholes (5) of a high pressure gas container (1) are located between the sealing elements, which are sealed against the movable closure cap of the closure system. The sealing elements seal the high pressure gas container, and the closure body (2) comprises an aerodynamically designed bottom part (2'), which supports discharge of the gas from the boreholes via a ring.
