The invention relates to an airbag module (12) comprising a restraint airbag (30) which is inflated in a situation of restraint and, in an inflated state, has a restraining effect on an occupant (16), and at least one backup member (36, 36a, 36b) which, in a restraining state, is at least in portions in contact with the inflated restraint airbag (30) and is configured so that it backs the restraint airbag (30) and in particular absorbs a force (F) applied to the restraint airbag (30) by contacting a vehicle occupant (16), wherein, in the inflated state, the restraint airbag (30) is interposed between the backup member (36, 36a, 36b) and the vehicle occupant (16), wherein the backup member (36, 36a, 36b) is arranged, in an initial state, on or in the airbag module. The invention also relates to a vehicle seat and a vehicle comprising an airbag module according to the invention.

An airbag apparatus for a vehicle may include first and second inflators each configured to provide an inflation gas; a main cushion connected to the first inflator and deploying toward a passenger when the first inflator operates; a sub cushion connected to the second inflator and deploying along a first side surface of the main cushion to be overlappingly deployed with the main cushion at the first side surface and the front surface of the main cushion when the second inflator operates; and a controller configured to operate the first inflator to deploy the main cushion when a vehicle collision is detected, and configured to operate both of the first inflator and the second inflator to deploy both of the main cushion and the sub cushion when the vehicle collision is detected as an oblique collision at a least a predetermined angle.

An airbag device for a front passenger seat includes an airbag, two inflators each for feeding the airbag with an inflation gas, a case which holds the airbag and inflators, and a retainer which mounts the airbag and inflators on the case. One of the two inflators is a potentially-influential inflator whose inflation gas may influence the other inflator. The retainer includes a holding plate section which is disposed on an inner surface of the airbag, two insert openings for receiving main bodies of the two inflators, and a shielding wall which rises out of a position of the holding plate section between the two insert openings and extends to a vicinity of a height of the top end plane of the main body of the potentially-influential inflator. The shielding wall shields the other inflator from an inflation gas emitted by the potentially-influential inflator.
