4 . The airbag cushion of claim 2 , wherein the first pocket panel and the second pocket panel are provided separately from the main panel.

5 . The airbag cushion of claim 2 , further comprising a first tether connected between an end of the pocket portion and an inner surface of the airbag cushion.

6 . The airbag cushion of claim 2 , further comprising a second tether connected to an inner surface of the airbag cushion located orthogonal to a side surface of the pocket portion.

7 . The airbag cushion of claim 6 , wherein the second tether comprises:

a first end connected to a middle portion of the first pocket panel; and

a second end connected to an inner surface of the main panel facing a front upper portion of the pocket portion.

8 . The airbag cushion of claim 6 , wherein the second tether comprises:

a first end connected to a middle portion of the second pocket panel; and

a second end connected to an inner surface of the main panel facing a rear lower portion of the pocket portion.

9 . An airbag comprising:

an airbag cushion configured to be deployed within a vehicle cabin downwardly from a roof of a vehicle toward a front of a passenger of the vehicle; and

a pocket portion having a concave space at a portion of the airbag cushion and configured to support a head of the passenger when the airbag cushion is deployed,

wherein the airbag cushion comprises a main panel and a pair of side panels respectively disposed at two opposed sides of the main panel,

wherein the pocket portion has an entrance including an opening located at a middle portion of the main panel, and is embedded, in a pocket shape, within the airbag cushion,

wherein the pocket portion includes a first pocket panel and a second pocket panel that are joined together, and has a predetermined area at the middle portion of the main panel, in a front-to-back manner,

wherein both side surfaces of the first pocket panel and both side surfaces of the second pocket panel respectively are connected to each other such that the pocket portion has a pocket shape,

wherein the first pocket panel and the second pocket panel are symmetrical with respect to a boundary line at which the first pocket panel and the second pocket panel are connected to each other, and

wherein the first pocket panel and the second pocket panel are folded along the boundary line, and sewn together at both side surfaces thereof.
