Abstract
An airbag cushion including: a steering-side panel positioned on a steering wheel side; an occupant-side panel positioned on an occupant side; and a side panel connecting an edge of the steering-side panel and an edge of the occupant-side panel to form a side part of the airbag cushion. The steering-side panel has a shape to conform to the steering wheel, and the occupant-side panel has an inverted triangular shape having a larger area than the steering-side panel. The airbag cushion in an expanded and deployed state has a cross-sectional area that gradually increases from the steering-side panel toward the occupant-side panel in a cross section orthogonal to an axial direction from the center of the steering-side panel toward the center of the occupant-side panel.
