Abstract
An airbag device to be applied to a vehicle provided with A to C pillars, a door, and a side sill includes an airbag, a collision mode predictor, and a pressure controller. The airbag is deployed from a container to be disposed on a lower side of the side sill to a region on a vehicle-widthwise outside of a side surface of a vehicle body including the door. The airbag includes a first air chamber disposed mainly in front of the B pillar after being deployed and a second air chamber disposed mainly behind the B pillar after being deployed. The collision mode predictor predicts a collision mode of an object with the vehicle. The pressure controller increases or reduces at least either of internal pressures of the first air chamber and the second air chamber independently of the other, based on the predicted collision mode.
Claims15
An airbag device to be applied to a vehicle, the vehicle being provided with
- an A pillar, a B pillar, and a C pillar that are structural members provided in order from a front side on a side surface of a vehicle body of the vehicle and extending in a vertical direction,
- a door provided to be openable and closable at a door opening provided at one or both of a position between the A pillar and the B pillar and a position between the B pillar and the C pillar, and
- a side sill disposed along a lower edge of the door, the airbag device comprising:
- an airbag configured to be deployed from a container to be disposed on a lower side of the side sill to a region on a vehicle-widthwise outside of the side surface of the vehicle body comprising the door, in response to a symptom of collision of an object with the side surface of the vehicle body, the airbag comprising a first air chamber configured to be disposed mainly in front of the B pillar after being deployed and a second air chamber configured to be disposed mainly behind the B pillar after being deployed;
- a collision mode predictor configured to predict a collision mode of the object with the vehicle;
- and
- a pressure controller configured to control an internal pressure of the first air chamber and an internal pressure of the second air chamber,
- wherein, based on the collision mode predicted by the collision mode predictor and after the airbag is deployed, the pressure controller;
- increases or decreases one of an internal pressure of the first air chamber and an internal pressure of the second air chamber independently of the other internal pressure;
- or
- increases or decreases the internal pressure of the first air chamber and the internal pressure of the second air chamber independently of each other.

- a collision mode predictor configured to predict a collision mode of the object with the vehicle;
- a pressure controller configured to, based on the collision mode predicted by the collision mode predictor, increase or reduce one of an internal pressure of the first air chamber and an internal pressure of the second air chamber independently of the other internal pressure, or increase or reduce the internal pressure of the first air chamber and the internal pressure of the second air chamber independently of each other;
- and
- an airbag mover configured to move the airbag in a front-rear direction with respect to the side surface of the vehicle body, based on the collision mode predicted by the collision mode predictor.
