An air bag (10) includes a main panel (40) which defines an inflation fluid volume for receiving inflation fluid. The main panel (40) includes a generally rectangular front portion (230) comprising four side panels (60, 62, 64, 66) and having an opening (232) for connection with an inflation fluid source. The main panel (40) includes a rectangular back portion (240) for engagement with the vehicle occupant, and four pleat portions (250, 260, 270, 280). The front portion (230) and the back portion (240) of the main panel (40) provide the air bag (10) with a generally pillow-shaped configuration when inflated. The air bag (10) has four corners when inflated. Each one of the pleat portions (250, 260, 270, 280) of the main panel (40) is disposed at a respective corner of the air bag (10). The pleat portions (250, 260, 270, 280) are disposed between the front portion (230) and the back portion (240) of the main panel (40) when the air bag (10) is deflated. The pleat portions (250, 260, 270, 280) are disposed outside of the pillow-shaped configuration when the air bag (10) is inflated.
