Abstract

Airbag housings that each house an airbag are respectively provided beneath the lateral face of the driver's seat backrest and the lateral face of a front passenger seat backrest inward in a vehicle width direction. The airbags are inflatable and deployable inwardly in the vehicle width direction as well as in a fore-and-aft direction and a vertical direction of the vehicle.

First claim

The invention claimed is:

1. An airbag device used in a vehicle having seats disposed apart from each other in a vehicle width direction, the airbag device comprising:
an airbag that is disposed in each of at least one pair of adjacent seats,
wherein the airbags of the at least one pair of adjacent seats are inflatable and deployable substantially simultaneously between the adjacent seats, and
wherein the airbags of the at least one pair of adjacent seats include a far side face including a contact region, each far side face of the airbags is contactable with each other in the contact region,
wherein the airbags are inflatable and deployable such that the contact region of the far side face of each airbag is equally disposed in relation to the seats in a fore-and-aft direction of the vehicle, and
wherein an outer surface of the inflated and deployed airbag includes a far side face being an inner-side face of the airbag in the vehicle width direction, the far side face including an anti-slipping agent being applied thereto.

2. The airbag device according to claim 1 , wherein
each of the airbags of the at least one pair of adjacent seats, when inflated and deployed, includes a portion facing the adjacent seat, the portion having a substantially planar shape extending in a fore-and-aft direction and a vertical direction of the vehicle, and
the portion in the substantially planar shape of one of the airbags of the at least one pair of adjacent seats is contactable with the portion in the substantially planar shape of the other one of the airbags of the at least one pair of adjacent seats, which has inflated and deployed from the adjacent seat.

3. The airbag device according to claim 2 , wherein each of the airbags of the at least one pair of adjacent seats is inflatable and deployable from a lateral face of a backrest that is provided in the corresponding seat, the lateral face facing the adjacent seat.

4. The airbag device according to claim 3 , wherein each of the airbags of the at least one pair of adjacent seats is inflatable and deployable backward from the backrest of the corresponding seat.

5. The airbag device according to claim 1 , wherein each of the airbags of the at least one pair of adjacent seats is inflatable and deployable from a lateral face of a backrest that is provided in the corresponding seat, the lateral face facing the adjacent seat.

6. The airbag device according to claim 5 , wherein each of the airbags of the at least one pair of adjacent seats is inflatable and deployable backward from the backrest of the corresponding seat.

7. The airbag device according to claim 1 , wherein an outer surface of an inflated and deployed airbag includes:
a near side face that is connected to an inflator and being an outer-side face of the airbag in the vehicle width direction;
a front face being a front-side face of the airbag in a fore-and-aft direction of the vehicle; and
a rear face being a rear-side face of the airbag in a fore-and-aft direction of the vehicle.

8. The airbag device according to claim 7 , wherein opposing near side faces of two airbags are in a substantially linear shape that extends in a fore-and-aft direction of the vehicle in a plan view.

9. The airbag device according to claim 1 , wherein opposed faces of two airbags are in a substantially linear shape that extends in a fore-and-aft direction of the vehicle in a plan view.

10. An airbag device used in a vehicle having seats disposed apart from each other in a vehicle width direction, the airbag device comprising:
an airbag that is disposed in each of at least one pair of adjacent seats,
wherein the airbags of the at least one pair of adjacent seats are inflatable and deployable substantially simultaneously between the adjacent seats,
wherein the airbags of the at least one pair of adjacent seats include a far side face including a contact region, each far side face of the airbags is contactable with each other in the contact region,
wherein the airbags are inflatable and deployable such that the contact region of the far side face of each airbag is equally disposed in relation to the seats in a fore-and-aft direction of the vehicle, and
wherein the far side face includes an anti-slipping agent being applied thereto such that the far side face of a first air bag of the airbags and the far side face of a second air bag of the airbags do not slip when contacting each other when the airbags are inflated and deployed.

11. An airbag device used in a vehicle having seats disposed apart from each other in a vehicle width direction, the airbag device comprising:
an airbag that is disposed in each of at least one pair of adjacent seats,
wherein the airbags of the at least one pair of adjacent seats are inflatable and deployable substantially simultaneously between the adjacent seats, and
wherein the airbags of the at least one pair of adjacent seats include a far side face including a contact region, each far side face of the airbags is contactable with each other in the contact region,
wherein the far side face includes an anti-slipping agent applied thereto.

12. The airbag device according to claim 11 ,
wherein each of the airbags of the at least one pair of adjacent seats, when inflated and deployed, includes a portion facing the adjacent seat, the portion having a substantially planar shape extending in a fore-and-aft direction and a vertical direction of the vehicle, and
wherein the portion in the substantially planar shape of one of the airbags of the at least one pair of adjacent seats is contactable with the portion in the substantially planar shape of the other one of the airbags of the at least one pair of adjacent seats, which has inflated and deployed from the adjacent seat.
