Abstract
An middle fabric portion (43) is disposed between a first fabric portion (41) and a second fabric portion (42) that constitute a pouch-shaped air bag (1). The middle fabric portion (43) divides the interior of the air bag (1) into a first compartment (45) and a second compartment (46). The two compartments (45,46) communicate by communicating openings (51) formed at locations near the outer edge of the middle fabric portion (43).

The first fabric portion (41) and the second fabric portion (42) communicate by a middle communicating portion (57) formed between the center communicating portion (53) and an outer edge portion (44). The communicating openings (51) are formed in the middle fabric portion (43), at locations near the outer edge of the middle fabric portion (43). When gas is introduced into the first compartment (45), the gas inflates the first compartment (45) into a flat shape and then flows through the communicating openings (51) into the second compartment (46) located at the occupant's side.
