Abstract

An airbag and an airbag apparatus includes a vent hole operable to close or open to a small extent until a passenger crashes into the airbag, and open or close to a large extent when the passenger crashes into the airbag. An interior of an airbag is partitioned into a first chamber at a center and a second chamber which surrounds the first chamber by an inner panel. A rear panel includes a vent hole for communicating the second chamber and the outside of the airbag. A lid member configured to cover the vent hole may be disposed on an outer surface of the rear panel. A tether may connect the lid member to the inner panel through the vent hole.
