Abstract
An airbag has the first bag expanding from an upper portion of an instrument panel toward a passenger, and the second bag disposed at a front part of the first bag. The first and second bags are respectively formed of two panels. The first bag has a length smaller than that of the second bag in the lateral width direction. When the second bag expands, the second bag abuts against a windshield or a ceiling of a passenger compartment, and contacts the upper body of the passenger for supporting.
