An occupant protection apparatus can reduce the impact on an occupant as much as possible to securely protect the occupant even when a first-stage ignition means is in failed state. In igniting a first squib 3a for driver seat, if determined that the first squib 3a for driver seat has been diagnosed to be in failed state (S204), a second squib 3b for driver seat in place of the first squib 3a for driver seat is ignited at the time when the first squib 3a for driver seat is normally scheduled to be ignited (S400), then the first squib 3a for driver seat is ignited at the time when the second squib 3b for driver seat is normally scheduled to be ignited (S600), which enables explosion of a driver airbag apparatus 3 without a delay as much as possible to improve the assurance and reliability of occupant protection. |
