Airbagvorrichtung zum Anbringen an einem Kraftfahrzeug

摘要

In an on-vehicle airbag apparatus including an airbag housing (25) having a breakably weakened portion (25d), an airbag to be stored in the folded state in the aforementioned airbag housing so that the aforementioned weakened portion is broken upon inflation, and an inflator for generating gas for inflating the airbag, the speed of response of air discharge from the airbag is sufficiently enhanced. A shutter (32) that can open and close the air discharge port (31) is mounted on a case (30). The case (30), being formed of rigid material, is hermetically connected to an opening (26a) of the airbag (26) and is provided with the air discharge port (31). A shutter-driving inflator (33) for driving a shutter (32) from the closed position to the opened position when in operation is connected to the shutter (32).
