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

What is claimed is:

1. An inflatable life raft system for a rotorcraft having a fuselage, the system comprising:
a panel;
a hinge attached to the panel and to the fuselage, wherein the panel is hingedly connected to the fuselage by the hinge, and wherein the panel is selectively removable from the rotorcraft by rotation to a prescribed degree of the panel about the hinge;
a first adapter coupled to the fuselage;
a second adapter coupled to the fuselage;
a mechanism configured for selectively removing the panel from the rotorcraft;
an inflatable life raft deployable to an exterior of the rotorcraft upon removal of the panel from the rotorcraft; and
a backing plate removably coupled to both the first adapter and the second adapter, the backing plate located inboard of the panel, the backing plate being located so as to create a stowage space for the inflatable life raft between the backing plate and the panel;
wherein the backing plate is removable from the fuselage while the panel is closed;
wherein the hinge is located on an exterior surface of the rotorcraft; and
wherein the mechanism configured for selectively removing the panel is only accessed from inside the fuselage of the rotorcraft.

2. The inflatable life raft system according to claim 1 , further comprising:
a plurality of tool free fasteners;
wherein the plurality of tool free fasteners couple the backing plate to both the first adapter and the second adapter.

3. The inflatable life raft system according to claim 2 , wherein the panel has an outwardly bulging contour so as to create space for the inflatable life raft.

4. The inflatable life raft system according to claim 1 , wherein the mechanism is a pin mechanism for selectively detaching the panel from the fuselage of the rotorcraft.

5. The inflatable life raft system according to claim 4 , further comprising:
a handle operably associated with the pin mechanism, the handle being located so that an occupant of the rotorcraft can actuate the pin mechanism.

6. The inflatable life raft system according to claim 4 , the pin mechanism comprising:
a latch bracket coupled to the fuselage;
a keeper coupled to the panel; and
a pin sized for traversal through an opening formed by the latch bracket and the keeper.

7. The inflatable life raft system according to claim 4 , wherein the pin mechanism is located near an upper portion of the panel.

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