PURPOSE: An air-bag cushion with two chambers is provided to prevent a secondary damage to a face or a neck of passengers by inflating the airbag gradually. CONSTITUTION: An air-bag cushion with two chambers includes a cushion cover(100), partition(120), and a blocking unit(300). The cushion cover is comprised of a front and rear part. The rim of the front part is connected to the rear part to form an internal space. The partition divides the internal space of the cushion cover into a first and second chamber. The first chamber is connected to an inflator. A second chamber is not connected to the inflator. A vent hole of the partition transfers the gas between the first and the second chamber. If the inner pressure of the first chamber becomes over the constant pressure, the blocking unit opens the vent hole to flow the gas from the first chamber to the second chamber.
