A roof-mounted airbag includes a cushion having a first chamber and a second chamber deployed downward from a vehicle roof while being inflated toward passengers facing each other, and a support chamber deployed between the first chamber and the second chamber and configured to push intermediate portions of the first and second chambers toward the passengers facing each other.

To effectively retain a deployed airbag without increasing installation man hours, in addition to suppressing rotation of this airbag in a direction away from a seat. For example, a side airbag apparatus 1 installed inside a backrest SB of the seat S includes: an airbag 2; an inflator 3 provided inside the airbag 2; a tether 4; and a bracket 5. The airbag 2 is deployed in a first direction in which a base end side 2a thereof is attached to a seat back frame SBF and the tip side thereof is distant from the backrest SB. The tether 4 includes: one end 4a attached to the seat back frame SBF; and the other end which extends in the first direction on the outer surface of the airbag 2 in the deployed state so as to be attached to the part on the tip side 2b of the airbag 2. A bracket 5 is attached to the seat back frame SBF and provided in the direction in which the tether 4 extends. The tether 4 is supported by the front end of the bracket 5.

A roof mounted airbag is proposed. The roof mounted airbag includes: an airbag cushion having an upper portion fixed to a roof of a vehicle and configured to be expanded downward when gas is supplied therein; a vent hole formed on the airbag cushion, and configured to discharge the gas in the airbag cushion to the outside of the airbag cushion during opening of the vent hole; and a closing tether having a first end fixed to the roof of the vehicle, and a second end connected to the vent hole to close the vent hole when tension is applied thereto.

A vehicle center airbag may include a main cushion and a plurality of sub-cushions. The main cushion is mounted on a lateral surface of a seat back and is deployed in a forward direction, being positioned beside a passenger when a side collision occurs. The sub-cushions are configured to communicate with the main cushion and are deployed upwards from the top portion of the main cushion. When the sub-cushions are deployed, they extend in a forward-backward direction of the vehicle and are positioned above the torso of the passenger.

The present disclosure describes a roof airbag apparatus for mobility which protects the occupant seated in the cabin in such a manner that the roof airbag is deployed downward from the cabin roof, and safely protects the occupant from impact in such a manner that the occupant is securely restrained by the airbag as the deployment shape of the airbag is maintained.

A seat airbag apparatus for a vehicle is disclosed. A side cushion is deployed so as to protrude forward from a seatback in order to protect the lateral sides of an occupant, and a front cushion is deployed so as to protrude from the side cushion to the front of the occupant in order to protect the front side of the occupant. The deployment of the side cushion and the front cushion is limited by an upper dual-surface tether structure, formed by an upper-side surface tether and an upper-front surface tether, and a lower dual-surface tether structure, formed by a lower-side surface tether and a lower-front surface tether, thereby increasing force with which movement of the occupant is restricted, thus further enhancing an occupant protection effect.

A vehicle seat of a motor vehicle has a side airbag provided on the vehicle seat, and a tension band assembly which includes a first tension band and a second tension band. The first tension band has an upper end and a lower end. The upper end of the first tension band is fixed in the region of the upper end of the backrest of the vehicle seat while the lower end is arranged in the region of the seat surface of the vehicle seat. The second tension band has an upper end and a lower end. The upper end of the second tension band is fixed in the region of the head support on the vehicle seat while the lower end is rigidly connected to the first tension band below the upper end of the first tension band. The tension band assembly is rigidly connected to the side airbag.

An occupant protection device, protecting an occupant seated in a seat, includes: a seat belt; and an airbag which is arranged in an area of a lap belt in the seat belt. The airbag includes a bag body and a regulatory tether. A thigh abutment surface abutting on a thigh of the occupant is arranged on a lower surface side of the bag body, and an upper body restraining surface restraining an upper body of the occupant is arranged on a rear surface side. The regulatory tether connects a base end to a rear surface side of an upper-lower intermediate portion of the bag body and connects a tip extending downward from the base end to the lap belt side and a length dimension is set a dimension in which a connecting portion connecting the base end of the bag body can be pulled toward the lap belt side.

A side airbag device capable of restricting an occupant from moving to the inner side in the vehicle width direction while restraining the head of the occupant is inflatable and deployable in a space beside an occupant seated in a vehicle seat. The side airbag device includes an inflator configured to generate a gas and a bag-shaped airbag inflatable and deployable in response to the gas upon activation of the inflator to protect a lateral portion of the occupant. The airbag includes a torso protection portion, and a head protection portion configured to be provided above the torso protection portion and inflatable and deployable between an upper portion of a shoulder of the occupant and a lateral portion of a head of the occupant. The head protection portion is bendable at an acute angle relative to the torso protection portion in an inflated and deployed state of the airbag.

A roof airbag arrangement includes an airbag, first and second guide rails, at least one first sliding member and at least one second sliding member. The airbag longitudinally extends along a length between first and second longitudinal sides and laterally extending along a width between first and second lateral sides. The first and second guide rails are on laterally opposite sides of the airbag, and define first and second channels, respectively. The at least one first sliding member is mounted within the first guide rail for translation within the first channel. The at least one second sliding member is mounted within the second guide rail for translation within the second channel. First and second pluralities of tethers connect the first lateral side of the airbag with the at least one first sliding member and the second lateral side of the airbag with the at least one second sliding member, respectively.
