Abstract
An airbag for protecting an occupant includes a panel forming the airbag and having an occupant counter surface with a head counter portion to face a head of the occupant when the airbag is inflated. A recess portion is formed in the head counter portion when the airbag is inflated. The airbag also includes a regulation member for regulating inflation of the head counter portion toward the occupant. The regulation member forms the recess portion by regulating inflation of the head counter portion toward the occupant upon inflation of the airbag. The regulation member is configured to release regulation after a predetermined time from a moment when the airbag starts inflation.
