Abstract
An airbag device includes a movement obtaining unit, an airbag, and an airbag controller. The movement obtaining unit is configured to obtain a movement of an occupant in an automobile. The airbag is deployable with different thicknesses into a gap between the occupant and a side portion of the automobile. The airbag controller is configured to restrict the thickness of the airbag that deploys toward the gap so that the airbag is inserted into the gap, if the airbag controller determines that the gap is smaller than a predetermined value on the basis of the movement of the occupant obtained by the movement obtaining unit.
Claims13
An airbag device comprising:
- a movement obtaining unit that is configured to gauge movement of a sitting occupant in an automobile;
- an airbag that is deployable with different thicknesses into a gap between the occupant and a side portion of the automobile;
- and
- an airbag controller that, after a collision detection is received by the airbag controller, is configured to restrict a thickness of the airbag that deploys toward the gap so that the airbag is inserted into the gap, if the airbag controller determines that the gap is smaller than a predetermined value on a basis of a determination by the movement obtaining unit, which determination by the movement obtaining unit is received by the airbag controller after the collision detection is received by the airbag controller, and wherein the movement obtaining unit is configured to obtain a degree of steering of the automobile and calculate movement of the occupant based at least in part on the degree of steering.
