Abstract

Systems and methods are provided for inflatable air pads for aircraft. One embodiment is an apparatus that includes an air pad affixed to a mount within an interior of an aircraft. The air pad includes a front face, a bladder that is inflatable within the air pad, and sides that constrain the front face of the air pad to extend a uniform distance outward from the mount when the bladder is inflated. The apparatus also includes an inflator that is coupled with the air pad and is configured to inflate the bladder from an undeployed volume to a deployed volume.

First claim

What is claimed is:

1 . An apparatus comprising:
an air pad affixed to a mount within an interior of an aircraft, the air pad comprising:
a front face;
a bladder that is inflatable within the air pad; and
sides that constrain the front face of the air pad to extend a uniform distance outward from the mount when the bladder is inflated; and
an inflator that is coupled with the air pad and is configured to inflate the bladder from an undeployed volume to a deployed volume.

2 . The apparatus of claim 1 wherein:
a maximum amount of the uniform distance during inflation of the bladder is between one and four inches.

3 . The apparatus of claim 1 further comprising:
tethers within the air pad disposed between the front face and the mount that constrain the front face to extend the uniform distance.

4 . The apparatus of claim 1 wherein:
the air pad is shaped in a form of a seat back of the aircraft.

5 . The apparatus of claim 1 wherein:
the air pad is mounted to a seat back of the aircraft.

6 . The apparatus of claim 1 wherein:
the air pad includes a gap at a location of a component installed in a seat back of the aircraft; and
the air pad further comprises an additional bladder at an edge of the gap which is inflated by the inflator expands into the gap during deployment.

7 . The apparatus of claim 6 further comprising:
a gap at a location of a display installed in the seat back, wherein the air pad further comprises an additional bladder that covers the display during deployment of the air pad.

8 . The apparatus of claim 1 wherein:
the air pad is mounted to a monument in the aircraft.

9 . The apparatus of claim 1 wherein:
the air pad further comprises vent holes that enable gas to exit the air pad after the air pad has been deployed.

10 . A system comprising:
an air pad affixed to a mount within an interior of an aircraft, the air pad comprising:
a front face;
a bladder that is inflatable within the air pad; and
sides that constrain the front face of the air pad to extend a uniform distance outward from the mount when the bladder is inflated;
an inflator that is coupled with the air pad and is configured to inflate the bladder from an undeployed volume to a deployed volume; a sensor that determines a deceleration of the aircraft; and a controller that receives input from the sensor indicating the deceleration of the aircraft, determines that the deceleration of the aircraft has exceeded a threshold value for longer than a period of time, and triggers the inflator for the air pad to deploy the air pad.

11 . The system of claim 10 wherein:
a maximum amount of the uniform distance during inflation of the bladder is between one and four inches.

12 . The system of claim 10 further comprising:
tethers within the air pad disposed between the front face and the mount that constrain the front face to extend the uniform distance.

13 . The system of claim 10 wherein:
the air pad is shaped in a form of a seat back of the aircraft.

14 . The system of claim 10 wherein:
the air pad is mounted to a seat back of an aircraft.

15 . The system of claim 10 wherein:
the air pad includes a gap at a location of a component installed in a seat back of the aircraft; and
the air pad further comprises an additional bladder at an edge of the gap which is inflated by the inflator and that covers the gap during deployment.

16 . The system of claim 15 further comprising:
a gap at a location of a display installed in the seat back, wherein the air pad further comprises an additional bladder that covers the display during deployment of the air pad.

17 . The system of claim 10 , wherein:
the air pad is mounted to a monument in the aircraft.

18 . The system of claim 10 , wherein:
the air pad further comprises vent holes that enable gas to exit the air pad after the air pad has been deployed.

19 . A method comprising:
receiving input from a sensor indicating a deceleration of an aircraft; determining that the deceleration of the aircraft has exceeded a threshold value for longer than a period of time; triggering an inflator for an air pad that is mounted within an interior of the aircraft and includes a bladder as well as sides of flexible material that constrain a front face of the air pad to extend a uniform distance outward when the bladder is inflated; and deploying the bladder by inflating the bladder.

20 . The method of claim 19 wherein:
the threshold value is sixteen Gravities (G's), and the period of time is two milliseconds.
