Airbag, preferably OPW airbag, for a vehicle

An airbag configured to be set from an uninflated state to an inflated state by an inflation operation to protect an occupant of a vehicle,

• wherein the airbag has at least two fabric layers which are connected to one another in such a way that a central inflow region forming a first airbag chamber and at least two wing regions forming respective second airbag chambers extending away from or radially from the inflow region are formed, so that during the inflation operation of the airbag, a gas can first flow into the central inflow region and then from the central inflow region into the respective wing regions,
• wherein distal end portions of the at least two wing regions are connected to one another via a flat tensioning element, so that during the inflation operation of the airbag the distal end portions move in a depth direction of the airbag away from the inflow region or move axially away from the central inflow region and in the inflated state of the airbag stretch or radially tension the flat tensioning element in the depth direction away from the inflow region or axially spaced from the central inflow region,
• wherein the airbag is configured as a one-piece woven (OPW) airbag with warp threads and weft threads woven into the woven fabric layers in the central inflow region and the respective wing regions, and
• wherein the warp threads and weft threads are woven together in such a way that the airbag forms the central inflow region in two layers and the respective wing regions in three layers, wherein in a first partial region (ETB) between a respective wing region and a second partial region which extends towards and finally forms the inflow region, the warp and weft threads of the second fabric layer emerge from the second fabric layer and float completely between the first fabric layer and the third fabric layer and are incorporated in the first fabric layer or in the third fabric layer in the second partial region.
