Abstract:
1. An inflator for an airbag comprising: a first bottle containing a pressurized oxidisable gas and a second bottle containing a pressurized oxidising gas, the first and second bottles being connected with a structure providing a chamber with at least one outlet for communication with such vehicle airbag, the first and second bottles each having a first discharge opening sealed by respective sealing means sealing off the interiors of the first and second bottles from the chamber, the inflator including first operating means which can be activated to cause or allow the seals provided by the sealing means to be broken to allow the gases from the first and second bottles to pass into the chamber and thence via the outlet or outlets into such airbag, at least one of the first and second bottles having a further discharge opening, sealed by its own sealing means, the inflator including further operating means operable with a different timing from the first operating means, or operable in a sub-set of the circumstances in which the first operating means is operable, for causing or allowing the seal provided by the sealing means for the further discharge opening to be broken to allow gas to escape from the further discharge opening into the chamber and thence to the airbag.
