In a preferred form, with a recessed portion of a retainer being fitted to a handlebar body portion, the airbag device is mounted and secured to the handlebar by a body mounting member.

Abstract: A technique is provided effective in preventing liquid from flowing from the exterior of an airbag cover into an airbag housing in a motorcycle airbag apparatus with a structure in which the airbag opening of an airbag housing is covered with an airbag cover. In one form, an airbag apparatus mounted to a motorcycle is constructed such that the upper end of a retainer wall is dispose above webbing through holes so as to prevent liquid influx from the exterior of a module cover through the webbing through holes into a retainer.

Abstract: A technique is provided that is effective in preventing a decrease in the strength of an airbag cover that covers the airbag housed in a housing and that is torn open along a tear line by the deploying force of the airbag. In one form, an airbag apparatus mounted to a motorcycle has a tear line that is torn open by the deploying force of an airbag at an erect portion of a module cover.

Abstract: A technique is provided effective in protecting the tether that connects the airbag to the vehicle in an airbag apparatus mounted to a motorcycle. In one form, an airbag apparatus mounted to a motorcycle has a bent portion having a smooth surface at a position where webbings for tethering an airbag to the vehicle body is in contact with a retainer.

Abstract: A technique is provided that is effective in smoothing the airbag deploying motion of an airbag apparatus to be mounted to a motorcycle. In one form, an airbag apparatus mounted to a motorcycle is constructed to hold the loose portions of elongated webbings that join an airbag to the vehicle body in a predetermined bunched state as a folded portion while the airbag is housed, and to release the hold upon the deployment of the airbag.

Abstract: A technique is provided that is effective in easily draining liquid entering the interior of a housing for housing a prefolded airbag of an airbag apparatus mounted to motorcycles. In a first form, an airbag apparatus mounted to a motorcycle has an opening at the bottom of a retainer, through which the water entering a retainer can be drained to the outside of retainer.

Abstract: A technique is provided that is effective in increasing occupant retraining performance of an airbag apparatus to be mounted to a motorcycle in a vehicle accident while reducing the size of an airbag. In one form, an airbag of an airbag apparatus mounted to a motorcycle includes a first airbag portion that deploys into the region of the occupant restraining region around the lumbar part of a rider; a second airbag portion that deploys into the region of the occupant restraining region around the chest of the rider; and an interference preventing portion that prevents interference with the arms of the rider with the first airbag portion and the second airbag portion.

In one form, an airbag apparatus mounted to a motorcycle is constructed to hold the loose portions of elongated webbings that join an airbag to the vehicle body in a predetermined bunched state as a folded portion while the airbag is housed, and to release the hold upon the deployment of the airbag.

Abstract: 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.
