An apparatus comprises a container (22) that defines a chamber (24) for receiving a mixture of gases. The mixture of gases comprises a combustible fuel gas portion and a noncombustible inflation gas portion for inflating an air bag (B). An outlet passage (100) is formed in the container (22) and provides fluid communication between the chamber (24) and the air bag (B) through a flow area. The outlet passage (100) is initially blocked to prevent fluid flow through the passage. An actuatable first initiator (122), when actuated, effects ignition of the combustible fuel gas portion of the mixture of gases and unblocking of the outlet passage (100) to allow gas to flow into the air bag (B). An actuatable second initiator (202), when actuated, changes the flow area of the outlet passage (100).
