| Zusammenfassung: | An inflator (10) for inflating a vehicle occupant protection device (34) comprises a vessel (12) containing stored gas (54) and ignitable material (62). The vessel (12) has a portion (30) that provides a first opening for fluid to flow from the vessel when the pressure in the vessel reaches a predetermined pressure. The inflator (10) also comprises an igniter (72) for igniting the ignitable material (62) and increasing the pressure in the vessel (12). The inflator (10) also comprises a control part (40) upstream of the portion (30) for controlling fluid flow to the first opening. The control part (40) defines a second opening (46) that increases in size as the pressure in the vessel (12) increases. |
