Abstract
An airbag and an airbag device, which are capable of readily improving expansion characteristics of the airbag and reducing manufacturing cost, are provided. An airbagfor occupant at passenger's seat includes a first bagand a second bagwhich is provided inside of the first bag. An outside top face portionof the first bagand an inside top face portionof the second bagare brought into a sheet-like intimate contact with each other, and are detachably jointed at the jointing portion. The jointing portionis comprised of a breakable seam line. Gas is supplied into the second bagto thereby expand the first bag, and is supplied into the first bagvia a gas distributing portionto thereby expand the first bag. In a case where an occupant exists at a predetermined position, the jointing portionbreaks away, and the first bagthen expands to its maximum. In an OOP state in which the occupant exists in the proximity of the airbag device, a head part of the occupant holds the outside top face portionand disallows breakage of the jointing portion, so that expansion of the first bagto the occupant side can be restrained and the occupant can be protected with an appropriate force.
