An apparatus ( 10 ) for helping to protect an occupant ( 14 ) of a vehicle ( 12 ) includes a housing ( 26 ) and an air bag ( 22 ) supported by the housing. An inflator ( 24 ) is supported by the housing ( 26 ). The inflator ( 24 ) includes a first stage ( 40 ) including at least one first outlet passage ( 44 ) and a second stage ( 50 ) including at least one second outlet passage ( 54 ). The first and second outlet passages ( 44 and 54 ) are provided for discharging inflation fluid into the air bag ( 22 ). An anchor ( 110 ) is secured to the inflator ( 24 ) and at least partially blocks inflation fluid flow through the second outlet passage ( 54 ). The anchor ( 110 ) is configured to disconnect from the inflator ( 24 ) in response to inflation fluid discharged through the second outlet passage ( 54 ) when the second stage ( 50 ) is actuated. At least one tether ( 100 ) has a first end ( 102 ) connected to the air bag ( 22 ) and a second end ( 106 ) secured to the anchor ( 110 ).
