Abstract

A monument is configured to be positioned within an internal cabin of a vehicle. The monument includes a deployable portion. The deployable portion is configured to move from a non-deployed state into a deployed state when a force that meets or exceeds a predetermined threshold is exerted into the monument wall assembly.

Claims

1. A monument configured to be positioned within an internal cabin of a vehicle, the monument comprising:

a deployable portion, wherein the deployable portion is configured to move due to inertia of the deployable portion without being contacted from a non-deployed state into a deployed state in a direction that is away from a passenger seat that is aft of the monument when an acceleration of the monument meets or exceeds a predetermined threshold,

wherein the deployable portion comprises a deployable clearance panel within a monument wall assembly, wherein the clearance panel is configured to move from the non-deployed state into the deployed state in the direction that is away from the passenger seat that is aft of the monument due to the inertia of the deployable portion without being contacted when the acceleration of the monument meets or exceeds the predetermined threshold,

wherein the clearance panel comprises a first portion that is configured to pivotally secure to the monument wall assembly, and a second portion that is configured to couple to the monument wall assembly by at least one mechanism, and wherein the at least one mechanism is configured to allow relative motion upon acceleration of the monument that meets or exceeds the predetermined threshold due to the inertia of deployable portion without the monument being contacted.

2. The monument of claim 1, wherein the at least one mechanism comprises at least one shear pin.

3. The monument of claim 1, wherein the first portion comprises an upper end, and the second portion comprises a lower end.

4. The monument of claim 1, wherein the clearance panel comprises an upper segment pivotally connected to a lower segment.

5. The monument of claim 1, wherein the clearance panel is a pantographic clearance panel that is configured to move from the non-deployed state to the deployed state through pantographic motion.

6. The monument of claim 1, wherein the clearance panel comprises one or more bracing members that prevent the clearance panel from moving from the deployed state back to the non-deployed state.

7. The monument of claim 1, further comprising a covering over the clearance panel that conceals at least a portion of the clearance panel in the non-deployed state.

8. The monument of claim 1, further comprising a fixture secured to the deployable portion, wherein the fixture provides a useful mass that facilitates movement into the deployed state in the direction that is away from the passenger seat that is aft of the monument when the acceleration of the monument meets or exceeds the predetermined threshold.

9. The monument of claim 8, wherein the fixture is secured to a fore surface or an aft surface of the clearance panel.

10. The monument of claim 1, wherein the deployable portion comprises a main body of the monument, and wherein the main body is configured to move from the non-deployed state into the deployed state when the acceleration of the monument meets or exceeds the predetermined threshold.

11. The monument of claim 10, wherein the main body is configured to be secured to a portion of the internal cabin through at least one fitting including an anchored portion that connects to the main body through a frangible portion.

12. The monument of claim 11, wherein the main body is configured to be secured to a portion of the internal cabin through at least one fitting including one or more pivot hinges.

13. The monument of claim 11, wherein the main body is configured to pivot forward when the force that meets or exceeds the predetermined threshold is exerted into the monument.

14. The monument of claim 11, further comprising one or more frangible elements located proximate to one or both of floor fittings or ceiling fittings.

15. A monument configured to be positioned within an internal cabin of a vehicle, the monument comprising:

a deployable portion, wherein the deployable portion is configured to move due to inertia of the deployable portion without being contacted from a non-deployed state into a deployed state in a direction that is away from a passenger seat that is aft of the monument when a force that meets or exceeds a predetermined threshold is exerted into the monument,

wherein the deployable portion comprises a deployable clearance panel within a monument wall assembly, wherein the clearance panel is configured to move from the non-deployed state into the deployed state in the direction that is away from the passenger seat that is aft of the monument due to the inertia of the deployable portion without being contacted when the force that meets or exceeds the predetermined threshold is exerted into the monument wall assembly,

wherein the clearance panel comprises a first portion that is configured to pivotally secure to a floor of the internal cabin, and a second portion that is configured to couple to one of a fixed wall or a ceiling of the internal cabin by at least one shear pin, and wherein the at least one shear pin is configured to break upon exertion of the force that meets or exceeds the predetermined threshold due to the inertia of deployable portion without the monument being contacted.

16. A vehicle, comprising:

an internal cabin;

a plurality of seats within the internal cabin; and

a monument proximate to at least one of the plurality of seats, wherein the monument includes a deployable portion, wherein the deployable portion is configured to move due to inertia of the deployable portion without being contacted from a non-deployed state into a deployed state in a direction that is away from a passenger seat that is aft of the monument when a force that meets or exceeds a predetermined threshold is exerted into the monument,

wherein the deployable portion comprises a deployable clearance panel within a monument wall assembly, wherein the clearance panel is configured to move from the non-deployed state into the deployed state in the direction that is away from the passenger seat that is aft of the monument due to the inertia of the deployable portion without being contacted when the force that meets or exceeds the predetermined threshold is exerted into the monument wall assembly,

wherein the clearance panel comprises a first portion that is configured to pivotally secure to a floor of the internal cabin, and a second portion that is configured to couple to one of a fixed wall or a ceiling of the internal cabin by at least one shear pin, and wherein the at least one shear pin is configured to break upon exertion of the force that meets or exceeds the predetermined threshold due to the inertia of deployable portion without the monument being contacted.

17. The vehicle of claim 16, wherein the clearance panel comprises one or more bracing members that prevent the clearance panel from moving from the deployed state back to the non-deployed state.

18. The vehicle of claim 16, wherein the deployable portion comprises a main body of the monument, and wherein the main body is configured to move from the non-deployed state into the deployed state when the force that meets or exceeds the predetermined threshold is exerted into the monument.

19. The vehicle of claim 18, wherein the main body is secured to a portion of the internal cabin through at least one fitting including an anchored portion that connects to the main body through a frangible portion.

20. A monument configured to be positioned within an internal cabin of a vehicle, the monument comprising:

a deployable portion, wherein the deployable portion is configured to move due to inertia of the deployable portion without being contacted from a non-deployed state into a deployed state in a direction that is away from a passenger seat that is aft of the monument when a force that meets or exceeds a predetermined threshold is exerted into the monument,

wherein the deployable portion comprises a deployable clearance panel, wherein the clearance panel is configured to move from the non-deployed state into the deployed state in the direction that is away from the passenger seat that is aft of the monument due to the inertia of the deployable portion without being contacted,

wherein the clearance panel comprises a portion that couples to a fixed portion of the internal cabin by at least one shear pin, and wherein the at least one shear pin is configured to break upon exertion of the force that meets or exceeds the predetermined threshold due to the inertia of deployable portion without the monument being contacted.
