An inflator for a vehicle air-bag, the inflator comprising: a container initially containing a pressurised gas, the container having a vent opening formed in a wall thereof; a rupturable element which covers the vent opening, substantially sealing the interior of the container, the rupturable element being attached to the wall of the container at at least a first location; a first support which is attached to the wall of the container and movable with respect to the wall of the container between a first configuration, in which the first support supports a region of the rupturable element and prevents the rupturable element from rupturing, and a second configuration, the rupturable element being attached to the first support at at least a second location; a second support which, in an initial configuration, supports the first support and prevents the first support from moving from the first configuration to the second configuration, and which, in a final configuration, allows the first support to move from the first configuration to the second configuration; and an activation mechanism which, when triggered, moves the second support from the initial configuration to the final configuration. |
