Abstract

A video display assembly, suitable for use in an airplane seat, includes a video display and a chamber configured and dimensioned to receive the display when the display is disposed in a first substantially vertical plane. The display is connected to the chamber by an arm having a pair of end portions and a shank portion intermediate the end portions, a proximal one of the end portions being secured to the chamber and a distal other of the end portions being secured to the display. The proximal one arm end portion is pivotable in the first substantially vertical plane relative to the chamber to move the display between a stow orientation wherein the display is stowed in the chamber and an intermediate orientation wherein the display is outside of the chamber. The shank portion is pivotable in a substantially horizontal plane relative to the proximal one arm end portion to move the display between the intermediate orientation and a generally vertical use orientation wherein the display is in a second plane. The distal other arm end portion is pivotable relative to the shank portion to tilt the display between the generally vertical use orientation and a tilted use orientation wherein the display is tilted relative to the second plane for ease of viewing.

.

5. The assembly of claim 1 wherein said stowable video display is part of an airplane seat.

6. The assembly of claim 1 wherein said display is forcibly pivotable from either of said tilted and vertical use orientations into a breakaway orientation wherein said display is disposed outside of and entirely below said chamber.

7. The assembly of claim 1 wherein said second plane is a generally vertical plane substantially perpendicular to said first substantially vertical plane.

8. The assembly of claim 1 wherein said shank portion is of substantial length.

9. The assembly of claim 1 wherein said shank portion is at least 6 inches in length.

10. The assembly of claim 1 wherein said assembly is part of a seat, and said chamber has an open top enabling passage of said display therethrough and includes an armrest cover removably covering said chamber open top.

11. The assembly of claim 10 wherein said chamber includes a cover mounted on said chamber and movable between a first position closing said chamber open top and a second position exposing said chamber open top to permit passage of said display through said chamber open top.

12. The assembly of claim 10 wherein said one arm end portion is pivotable relative to said chamber through an angle of about 100°

.

13. The assembly of claim 10 wherein said one arm end portion is pivotable relative to said chamber through an angle of about 100°

, said shank portion is pivotable relative to said one arm end portion through an angle of at least 90°

, and said other arm end portion is pivotable relative to said shank portion through an angle of about 30°

.

14. The assembly of claim 13 additionally including means to limit the angle through which said one arm end portion, said shank portion and said other arm end portion may pivot.

15. The assembly of claim 1 wherein said assembly is part of a seat, and said chamber has an open end enabling passage of said display therethrough.

16. The assembly of claim 15 wherein said one arm end portion is pivotable relative to said chamber through an angle of about 228°

.

17. The assembly of claim 15 wherein said one arm end portion is pivotable relative to said chamber through an angle of about 228°

, said shank portion is pivotable relative to said one arm end portion through an angle of at least 90°

, and said other arm end portion is pivotable relative to said shank portion through an angle of about 30°

.

18. The assembly of claim 17 additionally including means to limit the angle through which said one arm end portion, said shank portion and said other arm end portion may pivot.

19. The assembly of claim 1 additionally including means precluding movement of said display to said stowed orientation except from said intermediate orientation.

20. The assembly of claim 19 additionally including a pillow block stationary relative to said chamber, and an indexing plate disposed intermediate said pillow block and said one arm end portion, said indexing plate being stationary relative to said pillow block under normal use conditions, said one arm end portion being secured to said indexing plate for rotation therewith when said display is not in said intermediate orientation.

21. The assembly of claim 20 where said indexing plate is forcibly rotatable relative to said pillow block.

22. The assembly of claim 21 additionally including means cooperatively defined by said pillow block and said indexing plate for frictionally resisting relative rotation thereof.

23.
