Abstract
An airbag includes a front portion having an upper part for receiving a head of the occupant, a middle part and a lower part. The upper part has an upwardly protruding curved edge without a linear portion, and two laterally protruding upper curved edges. The middle part has two laterally inwardly curved middle side edges extending smoothly from the laterally protruding upper curved edges. The lower part haw two laterally inwardly and downwardly curved lower side edges, and a downwardly protruding curved edge without a linear portion. The lower part has a lateral width greater than that of the upper and middle parts to thereby form laterally projecting portions for receiving occupant's arms. The downwardly extending curved edge at the lower part has a curvature greater than that of the upwardly extending curved edge at the upper part.
