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.

Abstract: An technique is provided for suppressing external force received by a connector from a housing body side, in an airbag apparatus for use in a motorcycle, which has a construction housing an inflator for generating gas for expanding an airbag at a gas-generating section, and a connector for connecting a harness for supplying electric current to an igniting section of the inflator in the housing body. In one form, an airbag apparatus mounted on a two-wheeled motor vehicle is constructed to prevent the retainer wall portion from directly interfering with a connector by intervening a vertical extending portion of a lower holder that holds a lower portion of an inflator at a space between the retainer wall portion and the connector.

Abstract: An air bag apparatus is provided on a motorcycle. The apparatus includes an air bag that is restricted so as not to be expanded toward a body constituent part, and is guided to be expanded toward a rider protection region in the expansion direction by providing the air bag so it is rolled and folded outwardly from the body constituent part of the motorcycle, allowing it to be expanded and inflated toward the rider protection region, which is formed in front of a motorcycle rider, and above the body constituent part of the motorcycle in the case of the forward collision of the motorcycle.
