A bi-lobular air bag (14) has first and second lobes (232 and 234) defined at least partially by a central recess (230). The air bag (14) includes a central panel (210) formed in an endless loop and including a longitudinal slit (276) that at least partially defines an opening (270) in the central panel. First and second side panels (212 and 214) have peripheries (290) interconnected with respective edge portions (250 and 252) of the central panel (210). A recess panel (216) has a periphery (286) interconnected with portions of the center panel on opposite sides of the longitudinal slit (276). The recess panel (216) is folded and has overlying portions interconnected to form a pleat (306) that helps define the first and second lobes (232 and 234) of the air bag (14).
