The air sack includes a wall defining an interior region of the air sack. The wall is formed to include an air loss opening in fluid communication with the interior region of the air sack. The apparatus also includes a flow control assembly having a conduit in fluid communication with the interior region of the air sack and with the interior region of the manifold. The flow control assembly also includes a check valve mounted in the conduit to prevent the flow of pressurized fluid through the conduit from the interior region of the air sack to the interior region of the manifold.
