1. An airbag comprising:
- an airbag body that is formed in a bag shape by joining a peripheral edge of a passenger-facing surface facing a passenger in an inflated state and a peripheral edge of a passenger-opposite surface opposite to the passenger-facing surface in the inflated state;
an inlet of pressurized fluid that is formed on the passenger-opposite surface;
a vent hole that is formed on the passenger-opposite surface and that is configured to communicate inside and outside of the airbag body;
a regulation portion that is provided inside of the airbag body and that is configured to regulate discharge of the pressurized fluid from the vent hole; and
a coupling portion that is configured to temporarily join the passenger-facing surface and the passenger-opposite surface and that is breakable,wherein the regulation portion comprises;
a connecting member that is configured to regulate a thickness of the airbag body in the inflated state;
a vent hole cover that is configured to cover the vent hole and that has one end portion which is supported by the passenger-opposite surface and an other end portion which is joined to the coupling portion; and

Abstract
An airbag includes an airbag body formed by joining front and rear panels, an inlet of pressurized fluid, a vent hole communicating inside and outside of the airbag body, a regulation portion regulating discharge of the pressurized fluid from the vent hole and a coupling portion temporarily joining the front and rear panels. The inlet and the vent hole are formed on the rear panel. The regulation portion includes a connecting member, a vent hole cover and a link member. The connecting member regulates a thickness of the airbag body in the inflated state. The vent hole cover covers the vent hole and has one end portion supported by the rear panel and the other end portion joined to the coupling portion. The link member has one end portion joined to the vent hole cover and the other end portion joined to the connecting member.
