Patent attributes
An airbag configuration technology which contributes to intensive protection of a rider of a motorbike in case of accident, and other technologies related thereto are provided. An airbag apparatus including an airbag and an elongated webbing for anchoring the airbag to the vehicle body side is mounted to a motorcycle as a motorbike. The airbag is deployed and inflated while projecting toward a rider protecting area in case of a front collision of the motorcycle. The webbing holds the front side of the airbag with respect to the vehicle body via an extending portion which abuts against the outer surface of a front-side panel-forming cloth from the back side of the vehicle body when deployment and inflation of the airbag are completed, so that the movement of the airbag toward the front of the vehicle body is restricted by a tensile strength of the webbing, and the movement of the airbag in the direction of projection is allowed in the process of deployment and inflation of the airbag.
