An airbag, which is a one-piece woven airbag that is 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 a plurality of fabric layers including two fabric layers in certain regions and three fabric layers in other certain regions, wherein the plurality of fabric layers are one piece woven and connected to one another in such a way that a plurality of airbag chambers are formed,
• wherein the airbag chambers in the inflated state are each formed as tubular chambers which extend and/or are arranged in the inflated state in such a way that an outer shape of the airbag assumes a shape of a tube with an oval or elliptical cross-section or a hollow cylinder with a circular or ring-shaped cross-section, and
• wherein the plurality of airbag chambers formed as tubular chambers extend in the inflated state in an axial direction of the airbag formed in the shape of the tube or hollow cylinder and are radially offset with respect to one another in such a way that a group of inner airbag chambers arranged next to one another in a circumferential direction and a group of outer airbag chambers arranged next to one another in the circumferential direction are formed.
