Abstract: The present invention relates to an airbag including: an inflator; and an airbag cushion which is deployed by gas flowing into the airbag cushion from the inflator, in which the airbag cushion has a burst portion at least a part of which is torn from the airbag cushion so as to form a burst hole through which gas flowing into the airbag cushion is discharged to the outside.

Abstract: Provided is a passenger airbag apparatus that not only allows an airbag cushion to inflate in different sizes, depending on the types and positions of passengers in a passenger seat, but can automate a folding process, because the airbag cushion is made in 2D. The passenger airbag apparatus according to an exemplary embodiment of the present invention includes: a passenger sensor detecting information on the type and position of a passenger in a passenger seat; a controller outputting control signal on the basis of the information supplied from the passenger sensor; a gas generator generating different amounts of gas in response to the control signal transmitted from the controller; and an airbag cushion connected with the gas generator, having a folded portion that is folded and bound, and inflating in different sizes while the folded portion is unfolded in accordance with the amounts of gas supplied from the gas generator.
