an airbag cushion stored in a folded state in a pedestrian airbag room located between a roof and a headliner of a vehicle, and configured to be deployed to entirely cover both a windshield glass and an A-pillar by being expanded during deployment thereof, wherein the airbag cushion is configured such that a portion thereof corresponding to the windshield glass constitutes a windshield glass chamber and a portion thereof corresponding to the A-pillar constitutes an A-pillar chamber and a thickness of the windshield glass chamber and a thickness of the A-pillar chamber are different from each other;
a cover coupled to the roof by hinging at a portion where the roof extended forward is bent in a direction of the windshield glass, the cover further configured to lift, responsive to an expansive force of the airbag cushion when the airbag cushion is expanded, and thereby open an airbag cushion room in contact with the headliner; and
