AIRBAG APPARATUS FOR VEHICLE

摘要

The present invention discloses an airbag device for a vehicle. The airbag device for a vehicle comprises a vent hole, which is formed in an airbag cushion and discharges expansion gas inside; a cover, which is arranged on the outer side of the airbag cushion and is separated from the vent hole by tensile force in order to switch between the opening of the vent hole and the closing of the vent hole by being attached to the vent hole; a tether, which is connected to the cover in one end and is fixed inside the airbag cushion in the other end in order to supply tensile force to the cover through the vent hole; a tether guide, which supports the tether by being arranged on the inner surface of the airbag cushion, and which is structured so that the tether can pass through the inner side of the airbag cushion while being slid on the side; and a sealing unit, which supports the tether by being arranged between the vent hole and the tether guide, and which is structured so that the tether passing through the tether guide can pass through the sealing unit.
