There is proposed a vehicle seat configured to support an occupant (401) in a sitting position, the seat comprising: a squab (27), a backrest (28), and an airbag unit. The airbag unit comprises an inflatable bag (1) and an inflator (34). The airbag comprises an inflatable chamber (8, 9; 208). The airbag further comprises an inflatable guide (2), connected to the inflator and the inflatable chamber. Upon actuation of said inflator, said inflatable guide is at least partially inflated before the inflatable chamber, thereby initially urging the inflatable chamber away from the backrest of the seat. The airbag is configured such that after the inflatable guide is at least partially inflated, the inflatable chamber inflates into a deployed position in which it defines an inflated shroud which extends over said sitting position and provides lateral protection to said occupant of the seat in said sitting position.

A seat-mounted airbag device includes an inflator, an airbag body, and a guide member. The airbag body includes a front-rear chamber and a tip chamber. The front-rear chamber is deployed forward of a seat through a clearance between a window and a head of an occupant from a side portion of a headrest on a window side by gas ejected from the inflator and disposed between the window and the head of the occupant. The tip chamber is deployed inward in a seat width direction from an end portion of the front-rear chamber on a seat front side and disposed forward of a face of the occupant on the seat front side. The guide member protrudes from the side portion prior to deployment of the airbag body and is interposed between the airbag body and the head of the occupant.

The present disclosure relates to an airbag apparatus for a vehicle, which includes: an airbag cushion which is inflated and deployed in a forward direction from both sides of a passenger upon vehicle collision to protect both sides of the passenger; and an inflater configured to generate gas by an impact detection signal and to supply the gas to the airbag cushion, wherein the airbag cushion includes a first airbag configured to protect both sides or one side from passenger's shoulder to passenger's lower body part; and a second airbag configured to protect passenger's head and both sides of passenger's shoulder, and can restrict and protect passenger's upper body and lower body by inflating and deploying the first and second airbags toward both sides of the passenger upon vehicle collision.

A vehicle occupant protection device includes: an airbag main body that includes a front-rear chamber that is deployed to a seat front side along a side of a head of an occupant by a gas ejected from an inflator operated when a collision of a vehicle is detected or predicted, and a tip end chamber that is deployed inward in a seat width direction from an end portion of the front-rear chamber on the seat front side; and a headrest that includes a main body portion that supports the head of the occupant from a seat rear side, and a side portion that is provided on at least a side of the main body portion, that protrudes to the seat front side until a deployment of the front-rear chamber is completed, and that is interposed between the front-rear chamber and the head of the occupant.

An airbag assembly includes: an air bag mounted to a vehicle seat and capable of inflating from an undeployed state to a deployed state, wherein in the deployed state, the air bag extends along the head and torso of an occupant in the vehicle seat arranged to surround the head and torso of the occupant and a strap for mounting the air bag to the vehicle seat and having a first section a second section wherein in the deployed state, the strap is tightened, the first section being mounted to the air bag on an outer surface of the air bag in an extension direction of the air bag and the second section extending on at least one outer side surface of the air bag in a direction at an angle with respect to the extension direction of the air bag

The present disclosure relates to an airbag apparatus for a vehicle, which includes: an airbag cushion which is inflated and deployed in a forward direction from both sides of a passenger upon vehicle collision to protect both sides of the passenger; and an inflater configured to generate gas by an impact detection signal and to supply the gas to the airbag cushion, wherein the airbag cushion includes a first airbag configured to protect both sides or one side from passenger's shoulder to passenger's lower body part; and a second airbag configured to protect passenger's head and both sides of passenger's shoulder, and can restrict and protect passenger's upper body and lower body by inflating and deploying the first and second airbags toward both sides of the passenger upon vehicle collision.

An airbag that prevents heavy interference with the head of an occupant during expansion and deployment even when the occupant is not seated in a vehicle seat in a regular position.

An airbag device 11, including an airbag 12 and an inflator 6 for supplying gas to the airbag 12. The airbag 12 is positioned to the sides of the center in the left-right direction of the vehicle seat 2 and has a pair of chambers 1a physically coupled by a coupling section 12a that deploy forward of the occupant 3 when expansion and deployment are complete. The pair of chambers 1a are respectively independent during expansion and deployment and expand and deploy frontward from both the left and right sides of the vehicle seat 2, having side protecting chambers 1 ab that cover at least the side sections 3b of the occupant 3. The side protecting chambers 1ab are coupled by coupling sections 12a positioned to the sides of the center in the left-right direction of the vehicle seat 2, and the coupling section 12a is thinner than the side protecting chambers 1ab at least during initial expansion and deployment.

A seat-mounted airbag device includes an inflator that is operated when a vehicle collision is detected or predicted and ejects gas and an airbag body that includes a front-rear chamber and a tip chamber. The front-rear chamber is deployed forward of a seat through a clearance between a window and a head of an occupant from a side portion of a headrest on a window side by the gas ejected from the inflator and disposed between the window and the head of the occupant. The tip chamber is deployed inward in a seat width direction from an end portion of the front-rear chamber on a seat front side and disposed forward of a face of the occupant on the seat front side. The airbag body housed in the side portion includes an outward wound portion wound outward in a roll shape with a seat up-down direction as an axial direction.

A seat-mounted airbag device includes a guidance member and an airbag body which includes a front-rear chamber and a distal-end chamber and is accommodated in a side portion of a headrest of a window-side vehicle seat in a state where the airbag body includes an outward winding portion. At the time of a front end collision, the front-rear chamber deploys from the side portion through a gap between the head of an occupant sitting on the window-side vehicle seat and the head of an occupant sitting on a central-side vehicle seat and is disposed in the gap. The distal-end chamber deploys inwardly from a front end part of the front-rear chamber. The guidance member projects from the side portion prior to the deployment of the airbag body so as to be disposed between the airbag body and the head of the occupant sitting on the central-side vehicle seat.

An airbag is installed in a seat, and since an airbag cushion is deployed from an upper side of the seat toward the front of a passenger to expand so as to cover the passenger, the upper body of the passenger is stably restrained. In addition, the airbag cushion is deployed while advancing forward so as not to be interfered with by the passenger by the guide wire, and the binding force of the airbag cushion is secured by the guide wire so that the protection performance for the passenger via the airbag cushion is improved.
