Airbag and airbag apparatus
First Claim
1. An airbag, including a vent hole and a restriction mechanism for restricting outflow of gas through the vent hole, whereinthe vent hole is formed in a surface opposite to an occupant facing surface of the airbag in the inflated state or in a side surface of the airbag in the inflated state, whereinthe restriction mechanism comprises:
- a lid member which is disposed inside the airbag to cover the vent hole; and
a tethering member which extends inside the airbag to connect the lid member and said occupant facing surface, whereinwhen the airbag is inflated, the lid member is prevented from moving to outside of the airbag and is overlaid on said vent hole by the tethering member so that the vent hole is closed or slightly opened, andas an occupant collides with the inflated airbag to depress said occupant facing surface, the lid member is pushed out of the airbag through the vent hole by the inner gas pressure of the airbag so as to open or widely open the vent hole.

Abstract
An airbag and an airbag apparatus in which a vent hole is in a closed state or a slightly open state until an occupant plunges into the airbag and the vent hole becomes to an open state or a widely open state when the occupant plunges into the airbag. The inside of the airbag 10 is partitioned by inner panels 22A, 22B into a first chamber 1 centrally located and a second chamber surrounding the first chamber 1. A vent hole 18 is formed in a rear panel 14 to allow the communication between the second chamber 2 and the outside of the airbag. A lid member 60 is provided to cover the vent hole 18 from the inside of the rear panel 14. A tether (tethering member) 70 connects the lid member 60 and the inner panels 22A, 22B. When the airbag 10 is inflated, the tether 70 is tensioned to prevent the lid member 60 from moving out of the airbag 10.
