An airbag 14 comprises a hub 16 defining an inflation chamber inflatable to an inflated position, and inflatable fins 20 connected to the hub and spaced from each other around a circumference of the hub, where each of the inflatable fins extends radially from the hub in the inflated position. The hub may include panels (17, figure 5) spaced apart from each other around the circumference of the hub in an alternating arrangement with the fins. The hub may include openings (54) so that the fins are in fluid communication with the hub, or alternatively the fins may be inflated independently of the hub. First and second sides (56, 58) of the fins may be connected by means of tethers (64). Alternatively the tethers may be connected to the hub and extend across the openings to the fins (figure 6). The airbag may be supported by a roof 26 of a vehicle 10, such that when inflated it extends down into the vehicle. The airbag may serve to cushion the impacts of several people sat facing each other when driving in an autonomous mode.
