The present invention relates to an airbag comprising: an inflator; and a cushion in which gas generated from the inflator flows in and is developed, wherein the cushion comprises a rupture unit which is torn to limit internal pressure as gas generated from the inflator is discharged, where a torn end is angularly formed. The airbag can be controlled with a structure of the cushion itself without an extra internal pressure controller, and has the same work process with existing airbags. A number of components are reduces since an extra tedder or a device is not needed. Accordingly, improvement of performance, convenience, simplification of processes, and cost reduction caused by decrease of a number of components and lightening are possible. |
