AIRBAG APPARATUS

An airbag apparatus includes an airbag configured to be deployed forward of a front of a vehicle body of a vehicle; a collision determiner configured to establish a pre-crash determination when a collision probability with a collision object is equal to or higher than a predetermined threshold; and an airbag deployment controller configured to, in response to the pre-crash determination, give to an inflator a command to supply deployment gas to the airbag and deploy the airbag. The airbag includes front air chambers provided in a front portion of the airbag and disposed in a vehicle width direction, a coupling member configured to couple front end portions of the front air chambers in the vehicle width direction, and a rear air chamber disposed between rear portions of the front air chambers and a front end portion of the vehicle body, and communicating with an inside of each front air chamber.
