Abstract

Provided are an aircraft airbag that inflates across a plurality of seats, an airbag device including this airbag, and an aircraft equipped with this airbag device. The airbag has a bag main body extending across three seats and in the left-right direction of the aircraft body, and partition panels that partition the inside of the bag main body into small chambers and corresponding to the seats. Gas from the inflator flows into the small chamber in the middle, and flows into the small chambers through the communication portions above and below the partition panels. When occupants are caught and thereby the pressures in the small chambers reach a predetermined value or more, vent holes open.

Claims

1. An aircraft airbag installed in front of seats of an aircraft, comprising:

a bag main body having a length such that it is continuously disposed in front of a plurality of seats;

one or more partition panels provided so as to partition the bag main body into a plurality of small chambers arranged in the longitudinal direction of the bag and to allow adjacent small chambers to communicate with each other; and

one or more vent holes provided in the bag main body.

2. The aircraft airbag according to claim 1, wherein the same number of small chambers as the number of the seats are provided, and the one or more partition panels are arranged such that one small chamber exists in front of one seat.

3. The aircraft airbag according to claim 1, wherein three or more small chambers are formed, and an inflator installation portion is provided in the bag main body facing the small chamber in the middle in the longitudinal direction of the bag main body.

4. The aircraft airbag according to claim 1, wherein the one or more vent holes are one or more constant-pressure vent holes that open when the pressure in the bag main body reaches a predetermined value or more.

5. The aircraft airbag according to claim 1, wherein the one or more partition panels connect the front part and rear part of the bag main body.

6. The aircraft airbag according to claim 1, wherein fasteners for fastening the ends in the longitudinal direction of the bag main body to an aircraft body member are provided.

7. The aircraft airbag according to claim 1, wherein each small chamber is provided with the vent hole.

8. The aircraft airbag according to claim 1, wherein three or more small chambers are provided,

the small chamber in the middle in the longitudinal direction of the bag main body is not provided with the vent hole, and

the small chambers at both ends in the longitudinal direction of the bag main body are each provided with the vent hole.

9. The aircraft airbag according to claim 5, wherein communication portions that allow adjacent small chambers to communicate with each other are provided between the upper edge and lower edge of each partition panel and the bag main body.

10. An aircraft airbag device comprising:

the aircraft airbag according to claim 1; and

an inflator for inflating the aircraft airbag.

11. An aircraft in which the airbag device according to claim 10 is installed in a wall in front of seats.
