An inflatable airbag assembly comprising: a housing to be mounted at a seatback of a seat of a vehicle; an inflator; and an inflatable airbag cushion to receive inflation gas from the inflator and to deploy from a packaged state within the housing to a deployed state extending forward from a side of the seatback, wherein the inflatable airbag cushion in the deployed state is to be positioned laterally adjacent to a vehicle seating position, the inflatable airbag cushion comprising: a first chamber to be inflated by the inflation gas to be positioned in the deployed state to receive one or more of a shoulder and a pelvis of an occupant seated in the vehicle seating position and moving in a transverse direction relative to a longitudinal axis of the vehicle, wherein first chamber in the deployed state forms a substantially toroidal shape defining an inner toroidal region positioned to receive a thoracoabdominal region of the occupant moving in the transverse direction relative to the longitudinal axis of the vehicle; and a first contact panel disposed across the inner toroidal region and coupled to the first chamber, wherein in the deployed state, at least a portion of the first contact panel is disposed between at least a portion of an occupant-facing side of the first chamber and the vehicle seating position; wherein upon inflation of the first chamber, the first chamber produces a first tension in the first contact panel the first tension configured to provide a first resistance to movement of the thoracoabdominal region of the occupant; characterized in that the inflatable airbag cushion further comprising a second contact panel disposed across the inner toroidal region of the first chamber and coupled to the first chamber; wherein the first contact panel and the second contact panel in combination with the first chamber define a second chamber; at least one of the first contact panel and the second contact panel comprises an orifice; and wherein upon deployment of the inflatable airbag cushion, air is drawn into the second chamber. a housing to be mounted at a seatback of a seat of a vehicle;
