Abstract

An airbag (10) has an inflatable chamber (301) defined by a main front panel (12) and a pair of side panels (24), (26). The airbag (10) has a vertically oriented recessed portion (20) on the main panel (12) located on a lower portion of an airbag (10), preferably vertically at or below a gas inlet passageway (30). The recessed portion (20) divides the airbag (10) into two lower lobe portions (40, 42) on each side of the recessed portion (20). Upon inflation an internal tether (50) is attached to the recessed portion (20) and is anchored at or adjacent to the gas inlet passageway (30) thereby limiting forward movement of the recessed portion (20) upon inflation. The airbag (10) is useful as a frontal airbag, particularly a passenger frontal airbag.
