An inflator for an air-bag comprises at least one gas bottle () containing pressurized gas. The gas bottle is sealed by a rupturable foil (). There is a support member () engaging the rupturable foil to maintain it in an unruptured state. The support member () is retained in an initial position by a part () of a piston element () which directly engages the support member (). The piston element () is associated with a squib () to drive the piston element from an initial position to a release position in which the piston element no longer engages the support member (). This permits the support member () to move to a position in which the foil () will rupture to permit gas to escape from the bottle. The preferred embodiment has two gas bottles each sealed by a respective foil each maintained by a support member which directly engages a single piston member.
