The present invention relates to an airbag for a vehicle, preferably an OPW airbag, configured to be set from an uninflated state to an inflated state to protect an occupant of the vehicle. According to the invention, it is provided that the airbag has at least two fabric layers which are connected to one another so as to form a central inflow region forming a first airbag chamber and at least two wing regions which form a respective second airbag chamber and which extend radially from the inflow region, so that during an inflation operation of the airbag, gas can first flow into the central inflow region and can then flow into the wing regions. The distal end portions of the at least two wing regions are connected to each other by a flat tensioning element such that during an inflation operation of the airbag, the distal end portions move axially away from the central inflow region and, in an inflated state of the airbag, the distal end portions of the at least two wing regions move axially away from the central inflow region. The flat tensioning element is radially tensioned at a distance axially spaced from the central inflow region.
本发明涉及一种用于车辆的气囊优选为OPW气囊,该气囊被配置为从未充气状态设置为充气状态以保护车辆的乘客。根据本发明,规定了气囊具有至少两个织物层,它们彼此连接,从而形成形成第一气囊室的中央流入区域和至少两个形成相应的第二气囊室并从流入区域径向延伸的翼区域,以便在气囊的充气操作期间,气体可以首先流入中央流入区域,然后从中央流入区域流入各个翼区域,至少两个翼区域的远端部分通过扁平张紧元件彼此连接,以便在气囊的充气操作期间,远端部分轴向远离中央流入区域移动,并在气囊的充气状态下,在与中央流入区域轴向间隔开的距离处径向张紧扁平张紧元件。
