It is provided an airbag arrangement for a vehicle-occupant-restraining system, comprising an airbag, wherein at least one airbag layer delimits an inflatable volume of the airbag; and at least one fastening tab, which is connected to the airbag layer and is intended for fastening the airbag on a vehicle component. The entire fastening tab is formed from a different material to that of the airbag layer.

A side airbag device including an airbag (2); an inflator (3); and an inner tube (4) formed of a fabric and covering discharge holes (3a) of the inflator (3). The inner tube (4) protrudes toward a center of the airbag (2) in a deployed state and a first end (4b) is closed in the direction of gas discharge, and second ends (4c) that are in a vehicle height direction of the airbag (2) in the deployed state are open. The inner tube (4) is folded back at a folded-back portion (4d) inside the airbag (2) when the airbag (2) is folded in a case where the side airbag device is installed in a vehicle seat back.
