Abstract

An inflatable life raft system for an aircraft includes a window coupled to a fuselage portion of the aircraft. A mechanism is used to selectively detach the window from the fuselage. An inflatable life raft is deployable to the exterior of the aircraft upon detachment of the window from the aircraft.

First claim

The invention claimed is:

1. An inflatable life raft system for an aircraft, the system comprising:
a window for the aircraft;
a pin mechanism for selectively detaching the window from a fuselage of the aircraft; and
an inflatable life raft mounted across an interior transparent surface of the window and deployable to the exterior of the aircraft upon detachment of the window from the aircraft.

2. The inflatable life raft system according to claim 1 , further comprising:
a window frame for housing the window, the window frame being configured for coupling to a fuselage portion of the aircraft.

3. The inflatable life raft system according to claim 1 , further comprising:
a handle operably associated with the pin mechanism, the handle being located so that an occupant of the aircraft can actuate the pin mechanism.

4. The inflatable life raft system according to claim 1 , further comprising:
a backing plate coupled to the fuselage of the aircraft, the backing plate located inboard of the window and the inflatable life raft.

5. The inflatable life raft system according to claim 1 , further comprising:
a backing plate coupled to the fuselage of the aircraft, the backing plate located so as to create a stowage space for the inflatable life raft.

6. The inflatable life raft system according to claim 1 , further comprising:
a window frame for housing the window,
a hinge releasably coupled between a lower portion of the window frame and the fuselage.

7. The inflatable life raft system according to claim 6 , wherein the hinge automatically detaches the window frame from the fuselage upon a prescribed rotation about a hinge axis, the hinge axis being defined by the hinge.

8. The inflatable life raft system according to claim 1 , the pin mechanism comprising:
a latch bracket coupled to the fuselage;
a keeper coupled to the window; and
a pin sized for traversal through an opening formed by the latch bracket and the keeper.

9. The inflatable life raft system according to claim 1 , wherein the pin mechanism is located near an upper portion of the window.

10. The inflatable life raft system according to claim 1 , wherein the window has an outwardly bulging contour so as to create space for the inflatable life raft.

11. The inflatable life raft system according to claim 1 , further comprising:
a mooring line coupled to the inflatable life raft.

12. An inflatable life raft system for a rotorcraft, the system comprising:
a window for the rotorcraft, the window being selectively detachable from the rotorcraft;
a mechanism and a hinge, the mechanism and the hinge being configured for selectively detaching the window from the rotorcraft; and
an inflatable life raft mounted across an interior transparent surface of the window and deployable to the exterior of the rotorcraft upon detachment of the window from the rotorcraft.

13. The inflatable life raft system according to claim 12 , further comprising:
a handle operably associated with the mechanism, the handle being located so that an occupant of the rotorcraft can actuate the mechanism.

14. The inflatable life raft system according to claim 12 , further comprising:
a backing plate coupled to an interior portion of a fuselage of the rotorcraft, the backing plate located inboard of the window, the backing plate being located so as to create a stowage space for the inflatable life raft.

15. The inflatable life raft system according to claim 12 , further comprising:
a window frame for housing the window,
the hinge being releasably coupled between a lower portion of the window frame and a fuselage of the rotorcraft.

16. The inflatable life raft system according to claim 15 , wherein the hinge automatically detaches the window frame from the fuselage upon a prescribed rotation about a hinge axis, the hinge axis being defined by the hinge.

17. The inflatable life raft system according to claim 12 , the mechanism comprising:
a latch bracket coupled to the fuselage;
a keeper coupled to the window; and
a pin sized for entry into an opening formed by the latch bracket and the keeper.
