A vehicle airbag includes a main panel to form a main chamber deployed toward an inner part of a vehicle, and a protrusion panel provided outside the main panel to form at least one protrusion chamber that communicates with the main chamber and protrudes toward the inner part of the vehicle based on the main chamber. The protrusion panel is folded to have a wrinkle part when the vehicle airbag is not inflated.

An airbag device for a vehicle including at least one airbag housing interface chamber that attaches to an airbag housing; at least one airbag cushion chamber downstream of the at least one interface chamber; an elbow that fluidly connects the housing interface chamber with the cushion chamber and configured so that it controllably regulates gas flow into the at least one airbag cushion chamber; the elbow having an internal configuration, which includes at least one opening that permits back and forth gas flow between the elbow and the at least one airbag cushion chamber, and which controls the directional deployment of the airbag cushion chamber so that upon deployment the downstream end of the cushion chamber exits an airbag housing outwardly in a first direction and then in at least one second direction, so that the direction of deployment of the cushion chamber changes in direction to thereby wrap at least partially around a structure of a vehicle of the vehicle and at least temporarily interpose the cushion chamber between any occupant and the vehicle structure.

A vehicle occupant protecting device including: an airbag that is accommodated at an upper portion of a vehicle seat, that receives a supply of gas from an inflator and is inflated and expanded toward a seat front side, and that includes a front inflating portion, which is inflated at a seat front side with respect to a head portion of a vehicle occupant, and a pair of left and right lateral inflating portions, which are connected to the front inflating portion and are inflated at sides of the seat with respect to the head portion, the airbag being structured as an integral bag body that covers the head portion; and reinforcing portions that extend in a seat vertical direction at an interior of a seatback, and that connect an upper portion and a lower portion of a seatback frame that structures a frame of the seatback.

An occupant protecting device including: a seat provided in a vehicle, the seat including a seat cushion, a seat back, and a headrest, and the seat being provided with an air bag that inflates and deploys at least to a front and both of left and right sides of a head of a seated occupant; and a control device that in the case of having detected or predicted a collision of the vehicle, causes the air bag to inflate and deploy, and in the case that the seat is facing an opposite side to a collision side when the collision has been detected or predicted, delays a timing of causing the air bag to inflate and deploy more compared to in the case that the seat is facing the collision side.

[Problem] To provide a side airbag apparatus capable of quickly and properly restraining a passenger in the initial stage of deploying an airbag, along with a vehicle seat including this side airbag apparatus. [Resolution means] The airbag includes: a first chamber which is deployed towards the front of the side support part of the seat; a second chamber which starts being deployed inside the first chamber in the vehicle width direction prior to this first chamber; and a gas guide which is arranged in the first chamber so as to introduce the expansion gas (emitted from the inflator) into the second chamber. An internal vent hole, through which the expansion gas introduced by the gas guide flows into the second chamber, is formed at the boundary part between the first chamber and the second chamber. The second chamber includes: an upper region and a lower region; and an intermediate region disposed between the upper region and the lower region. In addition, at least one of the upper region or the lower region is configured to be deployed so as to protrude more to the front of the vehicle than the intermediate region.

A seatbelt device is provided with a webbing and a bag body. The webbing is applied to the body of a vehicle occupant. The bag body includes a first layer at a webbing side and a second layer at an opposite side from the webbing, with the first layer disposed therebetween. The bag body is provided along a length direction of the webbing, fixed to one side of a thickness direction of the webbing and supported by the webbing, and disposed between the webbing and the body of the vehicle occupant in a state in which the webbing is applied to the body of the vehicle occupant. The bag body is inflated by fluid being supplied thereinside. A joined portion at which the first layer and second layer are locally joined together is formed in the bag body. The inflation of the bag body is controlled by the joined portion.

A vehicle occupant protection device has an airbag main body that is formed as a single integrated bag body that covers a head portion of a vehicle occupant and includes a forward-inflating portion housed in a headrest or in a seat back of a vehicle seat, and which inflates and deploys when supplied with gas, and which inflates on a seat front side of the head portion, and a pair of left and right side-inflating portions which inflate on seat side portions of the head portion. This vehicle occupant protection device also has a sub-bag portion that is provided in at least one of the forward-inflating portion and the side-inflating portions, and that, when an internal pressure inside the airbag main body reaches a predetermined value or greater, inflates after receiving an inflow of gas from at least one of the forward-inflating portion and the side-inflating portions.

An airbag includes a mounting region, a protection inflatable region and an intermediate region disposed between the mounting region and the protection inflatable region. An area of the airbag from the protection inflatable region to the intermediate region is formed of two panels that are continuous with each other at leading end regions of the panels apart from the mounting region and the two panels in that area are connected at opposite edges by a joint. The protection inflatable region includes at the leading end a folded region that is formed by bringing the leading end regions of the two panels closer to the mounting region so as to form four or more layers of the panels, such that the folded region includes at least two inflatable spaces between the layers and a crease that is continuous with the joint.

A vehicle includes an occupant seating area and a body side having a first pillar and a second pillar disposed vehicle-forward of the first pillar. An airbag is mounted to the first pillar and inflatable to an inflated position. The airbag includes a side lobe extending from the first pillar toward the second pillar in the inflated position. The airbag includes a front lobe extending cross-vehicle from the side lobe vehicle-forward of the occupant seating area in the inflated position.

A front air bag for a vehicle is provided. The air bag includes an air bag cushion that has of a plurality of chambers and a gas flow passage that supplies each of the chambers with gas of an inflator. A variable valve selectively closes or opens the gas flow passage. Additionally, a controller determines a type of vehicle collision and operates the variable valve based on the collision type.
