Abstract

A far side airbag device comprising: a side airbag provided at a side section on a vehicle center side of a seatback, the side airbag comprising a rear inflation section and a front inflation section that inflates and deploys when supplied with gas through a communication path formed at a boundary with the rear inflation section; a fixing structure that fixes the side airbag to a seatback frame at the rear inflation section; and a tension cloth that receives tension and deploys accompanying inflation and deployment of the side airbag, wherein a vehicle front-rear direction front end side of the tension cloth is connected to the side airbag and a rear end side of the tension cloth is connected to the seatback frame, and in a deployed state, the tension cloth covers at least a portion of the rear inflation section as viewed from a side of the seatback.

Claims

1. A far side airbag device comprising:

a side airbag provided at a side section on a vehicle center side of a seatback in a vehicle width direction, the side airbag comprising a rear inflation section that inflates and deploys when supplied with gas and that restrains at least rear parts of the chest and abdomen of a seated occupant, and a front inflation section that inflates and deploys when supplied with gas through a communication path formed at a boundary with the rear inflation section and that restrains at least front parts of the chest and abdomen of the seated occupant;

a fixing structure that fixes the side airbag to a seatback frame at the rear inflation section; and

a tension cloth that receives tension and deploys accompanying inflation and deployment of the side airbag, wherein a vehicle front-rear direction front end side of the tension cloth is connected to the side airbag and a vehicle front-rear direction rear end side of the tension cloth is connected to the seatback frame, and in a deployed state, the tension cloth covers at least a portion of the rear inflation section as viewed from a side of the seatback.

2. The far side airbag device of claim 1, wherein:

the rear inflation section includes a shoulder restraint portion that restrains the shoulder region of the seated occupant in an inflated and deployed state; and

the tension cloth deploys to cover at least a portion of the shoulder restraint portion as viewed from the side of the seatback.

3. The far side airbag device of claim 1 comprising, as the tension cloth:

an outside tension cloth with the rear end side thereof connected to a portion of the seatback frame positioned to the rear side of the fixing structure in the vehicle front-rear direction, and that deploys at the seat width direction outside of the side airbag.

4. The far side airbag device of claim 3, wherein:

in plan view, a peripheral length of the outside tension cloth from a connection location with the side airbag to a connection location with the seatback frame is the same as or less than a peripheral length of the side airbag from a fixing location with the seatback frame to the connection location with the outside tension cloth.

5. The far side airbag device of claim 1, comprising, as the tension cloth, an inside tension cloth that deploys at the seat width direction inside of the side airbag.

6. The far side airbag device of claim 1, wherein:

the front inflation section includes a portion that inflates and deploys to the upper side of the rear inflation section in a vehicle up-down direction; and

the tension cloth deploys to cover at least an upper portion of the rear inflation section.

7. The far side airbag device of claim 1, wherein:

a length of the tension cloth in the vehicle up-down direction at the rear end side of the tension cloth is shorter than a length of the tension cloth in the vehicle up-down direction at the front end side of the tension cloth.

8. The far side airbag device of claim 1, wherein the front end side of the tension cloth is connected to the side airbag at a boundary between the rear inflation section and the front inflation section.

9. The far side airbag device of claim 5, wherein:

at least one out of the rear end side of the outside tension cloth or a rear end side of the inside tension cloth is connected to the fixing structure.

10. The far side airbag device of claim 1, wherein the front end side of the tension cloth is connected to the front inflation section.

11. The far side airbag device of claim 3, comprising, as the tension cloth, an inside tension cloth that deploys at the seat width direction inside of the side airbag.
