Abstract

An inflatable pod system on an aircraft includes an inflatable pod including a nozzle to receive air for inflation of the inflatable pod, and a hose assembly including a first end having an adaptor fitting that is configured to press fit with an air duct nozzle of an air duct of the aircraft and a second end having an adaptor configured to couple to the nozzle. In an example, the hose assembly delivers bleed air from the air duct, as provided by an environmental control system (ECS) of the aircraft, to the inflatable pod to inflate the inflatable pod. In another example, an air duct assembly line couples the ECS with the inflatable pod, and a control system triggers inflation via the air duct assembly line based on receipt of an electronic inflation signal.

First claim

What is claimed is:

1. An inflatable pod system on an aircraft, comprising:
an inflatable pod including a nozzle to receive air for inflation of the inflatable pod, and including a release valve to release air and deflate the inflatable pod; and
a hose assembly including a first end having an adaptor fitting that is configured to press fit with an air duct nozzle of an air duct of the aircraft and a second end having an adaptor configured to couple to the nozzle of the inflatable pod,
wherein when the hose assembly is coupled between the air duct nozzle of the air duct of the aircraft and the nozzle of the inflatable pod, the hose assembly delivers bleed air from the air duct of the aircraft, as provided by an environmental control system (ECS) of the aircraft, to the inflatable pod to inflate the inflatable pod.

2. The inflatable pod system of claim 1 , wherein the air duct of the aircraft is an overhead air duct positioned above a seat in the aircraft.

3. The inflatable pod system of claim 1 , wherein the inflatable pod is positioned substantially beneath a seat in the aircraft when deflated.

4. The inflatable pod system of claim 1 , further comprising:
one or more straps to couple the inflatable pod to an arm rest of a seat of the aircraft.

5. The inflatable pod system of claim 1 , further comprising:
an air duct assembly line coupling the ECS of the aircraft with the inflatable pod.

6. The inflatable pod system of claim 5 , wherein the inflatable pod comprises:
a first portion coupled to the air duct assembly line;
a second portion coupled to the first portion, wherein when inflated the second portion includes an upright cylindrical portion that is positioned in front of a seat in the aircraft; and
a third portion coupled to the second portion, wherein when inflated the third portion includes a circular top.

7. The inflatable pod system of claim 5 , wherein the inflatable pod is positioned substantially beneath a seat in the aircraft when deflated, and wherein the air duct assembly line couples to the inflatable pod at a location beneath the seat.

8. The inflatable pod system of claim 5 , further comprising:
a control system configured to trigger inflation of the inflatable pod via the air duct assembly line based on receipt of an electronic inflation signal.

9. The inflatable pod system of claim 8 , wherein the control system triggers inflation of the inflatable pod during landing of the aircraft.

10. The inflatable pod system of claim 8 , wherein the control system triggers inflation of the inflatable pod above a tray table proximate a seat in the aircraft.

11. The inflatable pod system of claim 1 , further comprising:
a seat; and
a tray table positioned on a backside of the seat, wherein the tray table is in a closed position when upright and in an open position when lowered to a horizontal position,
wherein the inflatable pod is positioned on the backside of the seat, and when inflated, the inflatable pod causes the tray table to be in the closed position.

12. The inflatable pod system of claim 1 , further comprising:
a seat; and
a tray table positioned on a backside of the seat, wherein the tray table is in a closed position when upright and in an open position when lowered to a horizontal position,
wherein the inflatable pod is positioned on the backside of the seat, and when inflated, the inflatable pod causes the tray table to be in the open position.

13. An inflatable pod system on an aircraft, comprising:
an inflatable pod positioned substantially beneath a seat in the aircraft when deflated;
an air duct assembly line coupling an environmental control system (ECS) of the aircraft with the inflatable pod, wherein the air duct assembly line couples to the inflatable pod at a location beneath the seat; and
a control system configured to trigger inflation of the inflatable pod via the air duct assembly line based on receipt of an electronic inflation signal, wherein when inflation is triggered the air duct assembly line delivers bleed air from the ECS of the aircraft to the inflatable pod to inflate the inflatable pod.

14. The inflatable pod system of claim 13 , wherein the control system triggers inflation of the inflatable pod during landing of the aircraft.

15. The inflatable pod system of claim 13 , further comprising:
a seat;
a tray table positioned on a backside of the seat, wherein the tray table is in a closed position when upright and in an open position when lowered to a horizontal position;
wherein when inflated, the inflatable pod causes the tray table to be in the closed position.

16. The inflatable pod system of claim 13 , wherein the inflatable pod comprises:
a first portion coupled to the air duct assembly line;
a second portion coupled to the first portion, wherein when inflated the second portion includes an upright cylindrical portion that is positioned in front of the seat in the aircraft; and
a third portion coupled to the second portion, wherein when inflated the third portion includes a circular top.

17. The inflatable pod system of claim 13 , wherein the inflatable pod comprises:
one or more straps to couple the inflatable pod to an arm rest of a seat of the aircraft.

18. A method for inflating an inflatable pod system on an aircraft, comprising:
coupling an environmental control system (ECS) of the aircraft with an inflatable pod via an air duct assembly line, wherein the air duct assembly line couples to the inflatable pod at a location beneath a seat in the aircraft;
triggering, by a control system, inflation of the inflatable pod via the air duct assembly line based on receipt of an electronic inflation signal; and
delivering bleed air from the ECS of the aircraft to the inflatable pod to inflate the inflatable pod.

19. The method of claim 18 , wherein triggering, by the control system, inflation of the inflatable pod comprises the control system triggering inflation of the inflatable pod during landing of the aircraft.

20. The inflatable pod system of claim 13 , wherein the inflatable pod further includes a release valve to release air and deflate the inflatable pod.
