Abstract

The airbag apparatus includes an airbag provided with a flap element for opening and closing an exhaust hole. The flap element includes a flap and an adjusting belt. The leading end region of the adjusting belt is sewn to the flap by a generally straight sewn seam and acts as a joint portion to the flap. The root region of the adjusting belt is joined to an open / close mechanism. A first terminal of the sewn seam disposed proximate a root region of the joint portion is located farther away from the open / close mechanism relative to a second terminal disposed proximate a leading end of the joint portion. The sewn seam is configured rupturable from the first terminal when the airbag inflates with the adjusting belt engaged with the open / close mechanism to separate the joint portion of the adjusting belt from the flap body so the flap uncovers the exhaust hole.

Description

technical field [0001] The present invention relates to an airbag device having an airbag configured to suppress internal pressure when inflated. Background technique [0002] At present, as an airbag device, as shown in JP-A-2000-43672, there is a structure in which a discharge hole is formed on the airbag to discharge part of the inflation gas, and the discharge hole can be connected to the opening and closing control device. The sheet member is opened and closed, and the opening and closing of the discharge hole is controlled in accordance with the seating position and body shape of the passenger, thereby suppressing the internal pressure when the airbag is inflated. [0003] In this airbag device, there is a structure in which a substantially annular stitching portion is provided along the entire circumference of the discharge hole, and a liner made of a disturbable sheet material and set to a size capable of closing the discharge hole is provided. , sewn on the airbag ...
