11. An airbag cushion comprising:
an occupant side panel configured to face an occupant when expanded and deployed;
a steering side panel that is opposite the occupant side panel; and
a side panel that connects the occupant side panel and the steering side panel at an outer edge of the occupant side panel and the steering side panel, wherein the side panel is formed as a single elongated panel with both ends of the side panel connected together at an upper end of the airbag cushion, wherein, when the airbag cushion is in an expanded and deployed state, a width in a front-to-back direction of an upper edge portion of the airbag cushion is greater than a width in the front-to-back direction of a lower edge portion of the airbag cushion; and
a tether extending in the front-to-back direction inside the airbag cushion to connect the steering side panel and the occupant side panel, wherein the tether is connected along a circular or elliptical shape sewing line near a center of the occupant side panel, wherein the tether forms a recessed part near the center of the occupant side panel when the airbag cushion is in the expanded and deployed state, and wherein a substantially flat part is formed in an area above the recessed part of the occupant side panel and is configured to come into contact with a face of the occupant, wherein a length of the tether causes the substantially flat part to be substantially vertical when the airbag cushion is in the expanded and deployed state.
