Abstract
An inflator () is disclosed for use in a safety device within a motor vehicle, for example, for inflating an air-bag. The inflator comprises at least one gas outlet () having an initial predetermined gas flow area. The or each gas outlet incorporates a deformable part () which is configured to deform, in response to a predetermined gas pressure, so as to increase the gas flow area of the gas outlet. The deformable part () may be surrounded by a slot () which initially constitutes the outlet. The deformable part includes a neck () which bends so that the deformable part () opens like a flap. The invention is particularly suited for incorporating in a hybrid multi-stage gas generator comprising two or more pyrotechnic charges that can be actuated in combination or independently. The variable-area gas flow outlet provides an arrangement to vary the cross-section or area of a gas flow passage in response to a high pressure of gas.
