Abstract
The airbag has a front portion, in which a front chamber is formed, a rear portion, in which a rear chamber is formed, and a partition, which partitions the front and rear chambers from each other. The partition has a communication passage for connecting the front and rear chambers to communicate to each other. A pressure regulating valve is located in the passage. At an early stage of a supply period during which an inflator supplies inflation gas to the airbag, the valve is closed to restrict flow of the inflation gas from the rear chamber to the front chamber via the passage. The valve is opened during the supply period to permit the inflation gas to flow therethrough. A front portion of the airbag is roll-folded, while a rear portion is accordion-folded. The airbag front portion and the airbag rear portion are located in front of the inflator.
