A cover member (25) for covering an air bag storage portion (22a) of a seat back (22) is formed by sewing up a seat-back front cover element (25a), side cover element (25b), etc. An air bag module (30) is stored in a module container (50) that is located in the air bag storage portion (22a). The module container (50), which is formed of a flexible sheetlike material, includes two opposite side portions (50a, 50b), which extend individually along two opposite side faces of the air bag module (30), and a rear end portion (50c), which extends along the rear end face of the air bag module (30). Front end portions (51) of the module container (50) are sewn together with the seat-back front cover element (25a) and the side cover element (25b) in a sewing portion (40) between the cover elements (25a, 25b). The sewing portion (40) and the front end portions (51) of the module container (50) open when the air bag (30) inflates. |
