To provide a motorcycle airbag device that contributes to the stabilization of the deployment behavior and the deployment posture of the airbag. An airbag device mounted on a motorcycle having a gas generator that generates an expansion gas, where the airbag is expanded by the expansion gas, and by deploying in front of the occupant, restrains forward movement of the occupant. Furthermore, the airbag has a stepped portion that protrudes forward when deployed and is supported by a structural portion around the top of the handlebars of the motorcycle.

Motorcycle airbag device

The configuration of an airbag module according to the present invention includes an airbag cushion, an inflator equipped in this airbag cushion, and housing for stowing this airbag cushion, wherein the housing has a convex polygonal shape in cross-section and has an opening on the upper side, and when the airbag cushion expands and deploys, a first pair of mutually opposed side surfaces expand separating from each other, the airbag module further comprises a cover covering the opening and side surfaces of the housing, and of the cover, the upper surface portion that covers the opening of the housing is formed with a first weak portion that extends in the longitudinal direction of the upper surface portion, is weaker than the area surrounding thereof, and is cleaved by the separation of the first pair of side surfaces.

Airbag module

To enable a retainer to be easily manufactured in accordance with a position where an inflator is disposed. In an airbag device for a saddled vehicle including: a retainer provided behind a head pipe; an inflator; and an airbag accommodated in the retainer, the airbag being configured to be expanded by gas released by the inflator and deployed in front of a passenger, the retainer has a box shape formed by assembling a plurality of components, the inflator is disposed to be offset outward in a vehicle width direction relative to the head pipe, the first component covers the inflator from a vehicle front side, a second component is provided behind the head pipe, and a third component is provided on a side of the passenger and is fitted to the second component and the first component from a back side.

Airbag device for saddled vehicle

A representative configuration of an airbag module including a folded or rolled airbag cushion, an inflator provided in the airbag cushion, and a case type housing for stowing the airbag cushion, wherein the housing is rectangular shaped in cross-sectional view and includes a first member forming at least one side wall of the rectangular shape, a second member that forms the remaining two or more side walls of the rectangular shape, and a rotational shaft connecting the first member and the second member enabling mutual relative rotation, and upon expansion and deployment of the airbag cushion, one of either the first member or second member rotates relative to the other around the rotational shaft causing the opening of an upper part of the case type housing to open up.

A configuration of the airbag module according to the present invention is an airbag module including an airbag cushion that is folded or wound, an inflator equipped in the airbag cushion, and a case-shaped housing where the airbag cushion is stowed. Herein, the housing includes four side walls, the upper part thereof being open; one side wall of the four side walls and two side walls positioned and connected on both sides thereof; and two extendable walls and at the opening above the four side walls that are in a folded state prior to expansion and deployment of the airbag cushion and open up when the airbag cushion expands and deploys.

To realize disposition of a retainer that can improve an occupant comfort of a passenger of a saddled vehicle. In a saddled vehicle including: a vehicle body including a head pipe that supports a steering system and a down frame that extends downward from the head pipe; a retainer provided behind the head pipe; an inflator; and an airbag accommodated in the retainer, the airbag being configured to be expanded by gas released by the inflator and deployed in front of the passenger, the retainer is provided with a fastening portion that fastens the retainer to the vehicle body, and the fastening portion includes a plurality of fastening members.
