Abstract
An apparatus for protecting a vehicle occupant comprises an Air bag having a stored deflated condition and an inflated condition for protecting a vehicle occupant. The apparatus also comprises an actuatable inflator (20, 320) for, when actuated, directing inflation fluid into the air bag. An energizable initiator (28, 228, 328) actuates the inflator (20, 320) upon energization. The initiator (28, 228, 328) comprises a foil, bridge section (126) and a flyer section (142). The foil bridge section (126) heats and explodes, in response to energization of the initiator (28, 228, 328), to propel the flyer section (142) to actuate the inflator (20, 320).
