<p>An air-bagged seat (20) comprises an air bag module (30) in a side portion (22a) of a seat back (22). The air bag module (30) includes a side air bag (32) that mainly spreads out forward in case of a collision of a vehicle. A cover member (25) for covering a side portion (22a) is formed by sewing up a seat-back front cover element (25a) cut in a given shape and a side cover element (25b) at a sewing portion (40), and thread in the sewing portion (40) is adapted to be broken when the air bag unfolds. Mark portions (50) for positioning for sewing operation are formed on edge portions (49) of the cover elements (25a, 25b) at the sewing portion (40). Each mark portion (50) has a projecting shape, such as the shape of a triangle.</p> |
