Airbag and airbag apparatus
First Claim
1. An airbag configured to be inflated and deployed by being supplied with gas into the interior thereof comprising:
- a vent hole formed on an outer shell of the airbag; and
opening and closing means configured to open and close the vent hole,wherein the opening and closing means is configured to maintain the vent hole in a substantially closed state until the inflation and deployment of the airbag are completed, and bring the vent hole into a fully-opened state before a flattening amount of the airbag reaches a predetermined reference value,wherein the opening and closing means includes a vent cover which can cover the vent hole, a tether connected to the vent cover and the interior of the airbag, and an insertion path for the tether formed in the airbag, and the tether is connected to a position which allows the vent hole to be brought into the fully-opened state before the flattening amount of the airbag reaches the predetermined reference value, andwherein the tether is connected to a position where the outer shell of the airbag assumes a state of being retracted inward by a predetermined length in an inflation-and-deployment-completed state of the airbag.
