and a knee side face restraint airbag that is disposed in a folded state at an outside in a vehicle width direction at an inside of a vehicle interior member, that inflates and deploys towards a vehicle cabin inside upon being supplied with gas generated from the inflator, and that restrains an outer lateral-side of a knee of a seated occupant. ## Claims ### Claim 1 A knee side face restraint airbag device comprising: an inflator that generates gas upon actuation; and a knee side face restraint airbag that is disposed in a folded state at an outside in a vehicle width direction at an inside of a vehicle interior member, that inflates and deploys towards a vehicle cabin inside upon being supplied with gas generated from the inflator, and that restrains an outer lateral-side of a knee of a seated occupant. ### Claim 2 (depends on 1) The knee side face restraint airbag device of claim 1, wherein: the knee side face restraint airbag is disposed in a folded state within a door trim of a side door, inflates and deploys from the door trim towards the vehicle cabin inside upon being supplied with gas generated from the inflator, and restrains the outer lateral-side of the knee of the seated occupant. ### Claim 3 (depends on 2) The knee side face restraint airbag of claim 2, wherein: an airbag module configured so as to include the inflator and the knee side face restraint airbag is supported by an impact beam that is disposed between a door outer panel and a door inner panel of the side door. ### Claim 4 (depends on 2) The knee side face restraint airbag device of claim 2, wherein: a speaker is installed to the side door; and the knee side face restraint airbag is configured so as to inflate and deploy from a speaker installation location towards the vehicle cabin inside. ### Claim 5 (depends on 1) The knee side face restraint airbag device of claim 1, wherein: a thickness along the vehicle width direction of the knee side face restraint airbag when inflated and deployed is set so as to be a distance from a door trim design face to the outer lateral-side of the knee of the seated occupant or greater. ### Claim 6 (depends on 1) The knee side face restraint airbag device of claim 1, wherein: the knee side face restraint airbag is configured such that when inflated and deployed the knee side face restraint airbag covers at least an area of up to and including a radius of 100 mm centered on a position located 200 mm further towards a vehicle rear and 500 mm further towards a vehicle top than an intersection point of a footrest provided in a foot space and a floor panel. ### Claim 7 (depends on 4) The knee side face restraint airbag device of claim 4, wherein: the knee side face restraint airbag removes or destroys a speaker grille portion of the speaker provided in a door trim design face and is inflated and deployed towards the vehicle cabin inside. ### Claim 8 (depends on 1) The knee side face restraint airbag device of claim 1, wherein: the knee side face restraint airbag is disposed in a folded state at an outside in the vehicle width direction at an inside of an instrument panel, is inflated and deployed from a design face of the instrument panel towards a vehicle rear and a diagonal lower side upon being supplied with gas generated from the inflator, and restrains the outer lateral-side of the knee of the seated occupant. ### Claim 9 (depends on 8) The knee side face restraint airbag device of claim 8, wherein: an airbag module configured so as to include the inflator and the knee side face restraint airbag is disposed within the instrument panel and is supported through a bracket by an instrument panel reinforcement that extends along the vehicle width direction. ### Claim 10 (depends on 8) The knee side face restraint airbag of claim 8, wherein: in a vehicle installed state, a length along a vehicle up-down direction of the knee side face restraint airbag when the knee side face restraint airbag is inflated and deployed is set to be twice a thickness along the vehicle width direction of the knee side face restraint airbag or greater. ### Claim 11 (depends on 8) The knee side face restraint airbag device of claim 8, wherein: the knee side face restraint airbag does not contact a front end portion of a seat cushion of a vehicle seat on which the occupant sits when inflated and deployed. ### Claim 12 (depends on 8) The knee side face restraint airbag device of claim 8, wherein: the knee side face restraint airbag abuts a front end portion of a seat cushion of a vehicle seat on which the occupant sits when inflated and deployed. ### Claim 13 (depends on 1) The knee side face restraint airbag device of claim 1, wherein: the knee side face restraint airbag is disposed in a folded state at an outside in the vehicle width direction at an inside of a cover of a seat cushion of a vehicle seat on which the occupant sits, causes the cover of the seat cushion to split, inflates and deploys towards a vehicle front side upon being supplied with gas generated from the inflator, and restrains the outer lateral-side of the knee of the seated occupant. ### Claim 14 (depends on 13) The knee side face restraint airbag device of claim 13, wherein: an airbag module configured so as to include the inflator and the knee side face restraint airbag is attached through a bracket to a seat cushion frame that supports the seat cushion. ### Claim 15 (depends on 13) The knee side face restraint airbag device of claim 13, wherein: the cover is configured such that it includes an upper face portion on which the occupant sits, and a side face portion disposed at an outside in the vehicle width direction of the upper face portion; the knee side face restraint airbag is configured such that it splits a sewn portion that runs in the vehicle front-rear direction at a boundary location between the upper face portion and the side face portion, and is inflated and deployed towards a vehicle front side; and the sewn portion is set to run through from a front side portion of the boundary location between the upper face portion and the side face portion of the seat cushion so as to extend past an upper side front end corner portion when running from a seatback side.
