An inflatable cushion 110 of an airbag cushion system 100 has an internal chamber 112, the internal chamber having an opening 113 allowing fluid communication between the internal chamber and an adjacent chamber 111 of the cushion. The cushion also has a throttle arrangement 114, configured to restrict flow of gas from the internal chamber through the opening to the adjacent chamber during an impact event. The throttle may permit flow of gas from the adjacent chamber to the internal chamber during inflation (figure 2A) and restrict flow of gas from the internal chamber to the adjacent chamber to a deflation flow rate (figure 2B), possibly when the inflated internal chamber is struck by an occupant. The throttle may comprise an unbiased check valve with one or more apertures (318, figure 3). The airbag cushion may comprise first and second internal chambers (412, 422, figure 4), each provided with separate throttles (414, 424) possibly providing different deflation flow rates.
