Airbag apparatus

An airbag apparatus to be applied to a vehicle, the airbag apparatus comprising:

• an airbag configured to be deployed forward of a front of a vehicle body of the vehicle;
• and
• circuitry configured to
• establish a pre-crash determination in a case where a collision probability with a collision object is equal to or higher than a predetermined threshold, and
• based on the pre-crash determination, give to an inflator a command to supply deployment gas to the airbag and deploy the airbag,
• wherein the airbag comprises
• front air chambers are bag-shaped and provided in a front portion of the airbag and arranged in line along a vehicle width direction,
• a coupling member configured to couple front end portions of the front air chambers in the vehicle width direction and formed into a strap shape by a flexible material configured to provide restrictive movement of the front end portions of the front air chambers,
• a rear air chamber is bag-shaped, different from the front air chambers, and disposed between rear portions of the front air chambers and a front end portion of the vehicle body, the rear air chamber communicating with an inside of each of the front air chambers, and
• communication openings are openings formed in the rear surface of the front air chambers and the front surface of the rear air chamber in such a manner that the inside of the rear air chamber and the inside of the front air chambers communicate with each other,
• wherein the front air chambers are deployed from the rear air chamber and project forward from the rear air chamber and the front end portion of the vehicle body.

A vehicle, comprising:

• an airbag configured to be deployed forward of a front of a vehicle body of the vehicle;
• a collision determiner configured to establish a pre-crash determination in a case where a collision probability with a collision object is equal to or higher than a predetermined threshold;
• and
• a 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,
• wherein the airbag comprises
• front air chambers are bag-shaped and provided in a front portion of the airbag and arranged in line along a vehicle width direction,
• a coupling member comprising a recessed portion configured to couple front end portions of the front air chambers in the vehicle width direction to contain a collision object and formed into a strap shape by a flexible material configured to provide restrictive movement of the front end portions of the front air chambers,
• a rear air chamber is bag-shaped, different from the front air chambers, and disposed between rear portions of the front air chambers and a front end portion of the vehicle body, the rear air chamber communicating with an inside of each of the front air chambers, and
• communication openings are openings formed in the rear surface of the front air chambers and the front surface of the rear air chamber in such a manner that the inside of the rear air chamber and the inside of the front air chambers communicate with each other,
• wherein the front air chambers are deployed from the rear air chamber and project forward from the rear air chamber and the front end portion of the vehicle body.
