Airbag and airbag device

An airbag that is normally accommodated in an instrument panel in a folded state and is inflated and deployed between a windshield and an occupant by gas being supplied thereto in an emergency, the airbag comprising:

• rectification means that is disposed in the airbag and controls the flow of the gas;
• wherein the rectification means comprises:
• a first opening at a lower, rearward portion of the rectification means through which the gas is supplied generally in a first direction such that part of the airbag at the occupant side is pressed against the instrument panel;
• a second opening at an upper, rearward portion of the rectification means through which the gas is supplied generally in a second direction such that the airbag is lifted upward;
• and
• a third opening at a lower, forward portion of the rectification means through which the gas is supplied generally in a third direction to a base end portion of the airbag at the windshield side located in front of the airbag,
• wherein the first, second and third directions are different from each other and arranged such that the airbag is inflated and deployed at a position suitable for restraining the occupant by the gas supplied from the second opening;
• the position of the airbag is stabilized by the gas supplied from the first opening;
• and the airbag is kept from bending by the gas supplied from the third opening to allow the airbag to be self-supporting when inflated and deployed without using a reaction force from the windshield.
