1. An airbag device comprising:
- a bag housing case;
an airbag housed in an deflated, folded state within the bag housing case;
a plate member disposed within and connected to the airbag; and
a bag pressure release mechanism provided in the bag housing case in confronting relation to an inside of the airbag, said mechanism being designed to open the airbag when an internal pressure of the airbag reaches a predetermined pressure after the airbag is inflated, thereby preventing an increase in the internal pressure of the airbag, the plate member being designed such that it covers the bag pressure release mechanism when the airbag is deflated and is released from coverage of the bag pressure release mechanism by an inflating force of the airbag when the airbag is inflated.

Abstract
An airbag device has a bag housing case, an airbag housed in the bag housing case, a plate member provided within the airbag, and a bag pressure release mechanism. When the internal pressure of the airbag reaches a predetermined pressure, the bag pressure release mechanism opens the airbag to prevent an increase in the internal pressure of the airbag. The plate member covers the bag pressure release mechanism when the airbag is in a deflated state. When the airbag is inflated, the plate member is released from coverage of the bag pressure release mechanism by an inflating force.

5. An airbag device comprising:
-
a bag housing case;
an airbag housed in a deflated, folded state in the bag housing case;
a strap member disposed within the airbag and connected to or formed integrally with the airbag; and
a bag pressure release mechanism provided in the bag housing case in confronting relation to an inside of the airbag, said mechanism being designed to open the airbag when an internal pressure of the airbag reaches a predetermined pressure after the airbag is inflated, thereby preventing an increase in the internal pressure of the airbag, the strap member being designed such that it covers the bag pressure release mechanism when the airbag is deflated and is released from coverage of the bag pressure release mechanism by an inflating force of the airbag when the airbag is inflated. - View Dependent Claims (6, 7, 8)
