Abstract: An air bag device is provided for a vehicle provided with at least two rows of seats including a front seat and a rear seat arranged in a front-rear direction, and configured such that relative positions of the front seat and the rear seat in the front-rear direction are changeable. The air bag device is mounted on a rear surface of a seatback of at least the front seat. The air bag device includes an air bag which is deployed rearwardly into a shape having a cavity portion therein in a vehicle side view by gas to be supplied from an inflator. The air bag includes a shape holding member for holding the air bag itself in a shape having the cavity portion therein against a gas pressure of an inner space of the air bag, when being deployed.

Abstract: An airbag of a rear-seat airbag device includes an deployment part which is deployed from a seatback of a front seat toward the vehicle rearward side and then toward a vehicle downward-and-forward side up to the seatback when the airbag is inflated and deployed, and the deployment part includes a stretch portion which is stretchable according to a tension acting on a tip portion of the deployment part when the airbag is inflated and deployed.

Abstract: The use state of the seatbelt is warned in the start-warning mode during the specified start-warning period of time after the starting of the power source of the vehicle. The warning by the warning device is disabled when the specified start-warning period of time has lapsed after the power source starting (step S15). The warning device to warn the use state of the seatbelt are enabled for the specified period of time (step S17-S20) when the use state of the seatbelt detected by the seatbelt use-state detecting device changes during the operation of the vehicle power source (step S12). When the seatbelt is changed from its state of use to its state of non-use, the warning is conducted with the harder warning stimulation characteristic (steps S18, S19). Accordingly, there can be provided the seatbelt use-state warning device which can warn the driver properly.
