  • Publication number: 20060196715
    Abstract: A seat cushion airbag unit is provided at each seat and includes a seat cushion airbag. The seat cushion airbag is disposed in an inboard portion of a seat cushion of the seat so as to support an inboard portion of buttocks of an occupant in the seat. The seat cushion airbag is changed from its inflated state from its shrunk state when the side crash or rollover of the vehicle is predicted by a controller. Thereby, the occupant's head is moved toward the center of the vehicle. Accordingly, the occupant protection device can promptly move the occupant's head toward the center of the vehicle, preventing the head from hitting against the vehicle roof, at the vehicle side crash or rollover.
