AIRBAG AND AIRBAG DEVICE

摘要

A vent hole communicating with an air chamber is opened in an airbag main body. A cover is disposed outside the air chamber of the airbag main body with respect to the vent hole. One end of the tether is connected to the cover via the vent hole, and the other end is connected to the airbag main body. If the tether is not pulled by the airbag main body, the vent hole is reliably opened to discharge gas to the outside. If the tether is pulled by the deployed airbag main body, the cover is partially drawn into the vent hole so that the cover is ensured to be in tight contact with the edge of the vent hole so as to reliably seal the vent hole.
