Abstract

The present disclosure relates to a monitor assembly for IFE systems. The monitor assembly comprises a screen assembly, a frame element that surrounds a perimeter of the screen or substantial portions thereof, and a cradle that is positioned behind the screen and at least partially encapsulates the frame element. The frame element is preferably made of a material that breaks more easily than the cradle material such that, upon an impact, the frame will break apart to absorb kinetic energy, while the cradle will remain intact and contain the broken frame pieces.

First claim

What is claimed is:

1. A monitor assembly for an In-Flight Entertainment (IFE) system, comprising:
a screen assembly including a front face, a rear face, and a side surface that extends between the front and rear faces;
a frame element positioned at least partially around the side surface of the screen assembly, the frame element including a front portion, a rear portion, and a side surface that extends between the front portion and the rear portion; and
a cradle having a rear portion and a frame element covering portion, wherein the frame element covering portion is positioned around at least a portion of the side surface of the frame element, wherein the frame element is configured to break upon an impact to form multiple frame element fragments, and wherein the cradle is configured to contain the multiple frame element fragments and remain intact upon the impact.

2. The monitor assembly of claim 1 , wherein the frame element comprises a plastic material.

3. The monitor assembly of claim 1 , wherein the cradle comprises a metal.

4. The monitor assembly of claim 1 , wherein the cradle comprises a metal alloy or casted material.

5. The monitor assembly of claim 4 , wherein the metal alloy comprises at least one of aluminum, magnesium, and zinc.

6. The monitor assembly of claim 1 , wherein the screen assembly comprises a touch panel.

7. The monitor assembly of claim 1 , wherein the screen assembly comprises a liquid crystal display (LCD) screen.

8. The monitor assembly of claim 1 , wherein the frame element covering portion of the cradle is positioned over at least at least 70% of an outer surface portion of the side surface of the frame element.

9. The monitor assembly of claim 1 , wherein the frame element covering portion of the cradle is positioned over at least at least 80% of an outer surface portion of the side surface of the frame element.

10. The monitor assembly of claim 1 , wherein the cradle encapsulates at least 70% of an outer surface of the frame element.

11. The monitor assembly of claim 10 , wherein the cradle encapsulates at least 80% of the outer surface of the frame element.

12. The monitor assembly of claim 1 , further comprising a microprocessor printed circuit board (PCB) fully enclosed between the cradle and a rear cover coupled to the rear portion of the cradle.

13. The monitor assembly of claim 12 , wherein the cradle is made of a metal and limits the electromagnetic interference.

14. The monitor assembly of claim 1 , wherein the cradle lacks cooling holes.

15. The monitor assembly of claim 1 , wherein the cradle comprises a single piece of material.

16. The monitor assembly of claim 1 , wherein the frame element is bonded to the screen.

17. The monitor assembly of claim 1 , wherein the frame element and the cradle are removably coupled to one another via at least one of screws and clips.

18. The monitor assembly of claim 1 , wherein the front portion of the frame element comprises a linear edge.

19. The monitor assembly of claim 1 , wherein the front portion of the frame element is positioned over a portion of the front face of the screen assembly.

20. A monitor assembly for an In-Flight Entertainment (IFE) system, comprising:
a screen assembly including a front face, a rear face, and a side surface that extends between the front and rear faces;
a frame element positioned at least partially around the side surface of the screen assembly, the frame element including a front portion, a rear portion, and a side surface that extends between the front portion and the rear portion;
a cradle having a rear portion and a frame element covering portion, wherein the frame element covering portion is positioned around at least a portion of the side surface of the frame element; and
at least one of the following:
(i) a microprocessor printed circuit board (PCB) fully enclosed between the cradle and a rear cover coupled to the rear portion of the cradle;
(ii) the cradle being made of a metal and limiting the electromagnetic interference;
(iii) the cradle comprising a single piece of material;
(iv) the frame element being bonded to the screen; and
(v) the front portion of the frame element being positioned over a portion of the front face of the screen assembly.
