Abstract

A vehicle far side airbag device includes: a splitting portion at a front side of a seat cover, at a side section at a vehicle center side of vehicle seatback, extends along a height of the seatback; an airbag inside the side section, deploys toward an outside of the side section while splitting the splitting portion, to protect an occupant from head to abdomen; a diffuser housed at a lower and rear side within the airbag, ejects gas from an inflator from an upper end opening and a lower end opening; and a tensioning cloth fixed to both a seatback frame and a location at a lower end of the splitting portion, is superimposed on the airbag in a stored state. A portion of the tensioning cloth is positioned further to a seatback lower side than the lower end opening of the diffuser in a deployed state.

First claim

What is claimed is:

1 . A vehicle far side airbag device comprising:
a predetermined splitting portion that is formed at a front portion side of a seat cover, at a side section at a vehicle width direction center side of a seatback of a vehicle seat, and that extends along a height direction of the seatback; an airbag that is stored inside the side section, that inflates and deploys toward an outside of the side section while splitting open the predetermined splitting portion on being supplied with gas, and that protects an occupant from a head to as far as an abdominal region; a diffuser that is housed at a lower portion side and a rear portion side within the airbag, and that ejects gas generated by an inflator from an upper end opening and a lower end opening; and a tensioning cloth that is fixed to both a seatback frame and a location at a lower end side of the predetermined splitting portion, that is superimposed on the airbag in a stored state in a seat side view, and in which at least a portion of the tensioning cloth is positioned further to a seatback lower side than the lower end opening of the diffuser in a deployed state of the diffuser.

2 . The vehicle far side airbag device of claim 1 , wherein:
the airbag is partitioned into a front bag section and a rear bag section by a partitioning section formed with a communication hole; and the diffuser is housed inside the rear bag section.

3 . The vehicle far side airbag device of claim 1 , wherein:
the tensioning cloth is disposed so as to be positioned further to an upper side of the seatback than a lower end of the airbag in the stored state.

4 . The vehicle far side airbag device of claim 1 , wherein:
the tensioning cloth is disposed in a position superimposed on the lower end opening of the diffuser in the deployed state, and a lower end of the airbag in the stored state in the seat side view.

5 . The vehicle far side airbag device of claim 4 , wherein:
the lower end of the airbag in the stored state is set further to an upper side of the seatback than the lower end opening of the diffuser in the deployed state.

6 . The vehicle far side airbag device of claim 4 , wherein:
the tensioning cloth is disposed in a position superimposed on the lower end of the airbag in the stored state in the seat side view, and is disposed such that the entire tensioning cloth is positioned further to the lower side of the seatback than the lower end opening of the diffuser in the deployed state.
