ABSTRACT:
An inflatable vehicle occupant protection device system (10, 110) for helping to protect a vehicle occupant in a crash event includes a module (12, 112), which may be mounted in a vehicle and includes an inflatable vehicle occupant protection device (24, 124). A mechanism controls flow of inflation fluid from an inflator (26, 126) to the protection device (24, 124). The mechanism also includes a first igniter (30, 130) and a second igniter (32, 132), which provide for inflation fluid flow from the inflator (26, 126) to the inflatable vehicle occupant protection device (24, 124). The system (10, 110) also includes a crash sensor (14, 114) for sensing a vehicle crash event and providing an activation signal. The igniters (30, 130 and 32, 132) are responsive to the crash sensor (14, 114) over a shared signal path (16, 116 and 18, 118) between the module (12, 112) and the crash sensor (14, 114). A delay device (46, 146) delays actuation of the second igniter (32, 132) for a predetermined time period after actuation of the first igniter (30, 130).
