A seat airbag apparatus for a vehicle and a method of controlling the operation thereof, includes side cushions deployed from the seatback, front cushions configured to be deployed from the side cushions, and inflators for the side cushions and inflators for the front cushions. The deployment operation of the side cushions and the deployment operation of the front cushions are respectively controlled depending on a normal seating mode and a relax mode of an occupant and a side collision and a front collision of the vehicle.

The airbag includes a bag body that deploys and inflates to cover the interior side of the window, and a strap having an upper end attached to an upper window frame, a lower end attached to a lateral frame, and an intermediate portion connected to the body. The strap has an insertion portion, which is inserted through the insertion hole of the body, on the intermediate portion, so that the part from the upper end to the insertion portion is an outer side portion, which is placed on the outside of the body in the inflated state, and the part from the insertion portion to the lower end is an inner side portion. When the inflation of the body is completed, the inner side portion is pressed to the inside of the vehicle by the front edge side inflation portion, and generates tension in the strap and the body.

The present invention provides a roof airbag for a vehicle, the roof airbag including an airbag cushion mounted on a roof panel of a vehicle and configured to deploy downward from the roof panel to a location between front and rear passengers seated while facing one another, a front tether configured to surround an outer portion of the airbag cushion and having one end connected to a front side of the airbag cushion and the other end connected to the airbag cushion, and a rear tether configured to surround the outer portion of the airbag cushion and having one end connected to a rear side of the airbag cushion and the other end connected to the airbag cushion, in which the front and rear tethers surround the outer portion of the airbag cushion while intersecting each other.

A vehicle airbag device comprises an airbag body including a front-rear chamber configured to pass a side of the head of an occupant seated in a vehicle seat and to deploy toward a seat front side as a result of gas being ejected from an inflator actuated, so as to be disposed at the side of the head of the occupant, a leading end chamber is configured to deploy toward a seat width direction inner side from a seat front side end portion of the front-rear chamber so as to be disposed at the seat front side of the head of the occupant, and a shoulder-contact section is configured to contact, from the seat front side, a first shoulder of the occupant so as to restrain the first shoulder, the first shoulder being at an opposite side from a second shoulder of the occupant across which a shoulder belt is worn.

Proposed is a roof airbag that is disposed at the roof of a vehicle and is deployed into an interior space of the vehicle. A bracket is provided to the roof. An inflator is connected to the bracket and configured to discharge an inflation gas when operated. An airbag cushion is provided to an airbag cover connected to the bracket in a foldable way and deployed into an interior space of the vehicle by the inflation gas supplied by the inflator. A tether is configured such that one end thereof is fixed to the roof side, and the other end of which is connected to the airbag cushion. The tether supports the airbag cushion so that, when the airbag cushion is deployed, the airbag cushion is deployed toward a seat.

The present invention provides a seat airbag device for a vehicle, the seat airbag device including an airbag cushion including a lateral chamber positioned at lateral sides of a passenger and configured to be deployed forward from a seatback of a vehicle, a front chamber configured to be deployed forward from an upper side of the seatback to surround the passenger, and an auxiliary chamber configured to be deployed from the front chamber toward a front side of the passenger so as to be positioned between the front chamber and the passenger, and a support tether extending from the seatback and connected to the airbag cushion to support the airbag cushion.

An assembly for a vehicle includes a middle console. The assembly includes a seatback including a vehicle-rearward side. The assembly includes an airbag supported by the middle console. The airbag is inflatable to an inflated position. The airbag in the inflated position includes a middle portion and an extension. The extension extends from the middle portion along the vehicle-rearward side of the seatback.

A seat airbag device for a vehicle is proposed. The seat airbag device includes an airbag cushion including a side chamber deployed forward from a seatback of the vehicle and located at a lateral surface of a passenger and a front chamber deployed from an upper portion of the seatback and arranged to be extended forward of the passenger and to wrap the upper side and front side of the passenger, and a support tether extended from the seatback and connected to the airbag cushion so as to support the airbag cushion.

An airbag apparatus includes two airbags. The airbags are respectively accommodated in side accommodation portions in a seat back. The airbags include two side inflation portions and two front inflation portions. Each airbag further includes a tether. Each airbag includes a non-inflation portion. Each tether includes a pass-through section at which the tether is passed through the non-inflation portion. A portion of each tether between the pass-through section and a distal end is arranged along a rear surface of the front inflation portion. A portion of each tether between the pass-through section and a basal end is arranged along an inner surface of the side inflation portion. The basal end of each tether is configured to be fixed to a rear end of the side inflation portion or the seat back. The distal end of each tether is fixed to a front end of the front inflation portion.

An assembly for a vehicle includes a seat having a seat bottom and a seatback supported by the seat bottom. The seat bottom and the seatback define an occupant seating area. The seat includes an airbag supported by an upper end of the seatback. The airbag is inflatable downwardly from the upper end of the seatback enclosing the occupant seating area between the airbag and the seatback. The seat includes a pyrotechnic device fixed to the seat below the airbag. The pyrotechnic device is connected to the airbag.
