An airbag cushion assembly, comprising:

• an airbag cushion configured to be positioned for deployment from a vehicle seat;
• and

• a first sew line extending along or adjacent to the first end of the mitt from an upper portion of the airbag cushion to a lower portion of the airbag cushion;
• a second sew line extending along or adjacent to the second end of the mitt from the upper portion of the airbag cushion to the lower portion of the airbag cushion;
• and
• a third sew line extending in between the first sew line and the second sew line from the upper portion of the airbag cushion to the lower portion of the airbag cushion.

An airbag cushion, comprising:

• a plurality of elongated chambers positioned adjacent to one another and extending from a lower end of the airbag cushion to an upper end of the airbag cushion;
• a mitt defined at least in part by a subset of the plurality of elongated chambers, wherein the airbag cushion is configured to deploy by extending in a first direction, bending the airbag cushion to form the mitt, and extending in a second direction at an angle relative to the first direction;
• at least one external tether coupled with the airbag cushion;
• and
