4. The protection and guide device according to claim 1 , further comprising a crankcase ( 40 ), inserted in a lower part of the direct-vision window parallel to a table ( 20 ) that is connected to the window support ( 14 ) of the direct-vision window, said crankcase ( 40 ) comprises a flange ( 42 ) that is oriented downward at a level of a free end defining the axis of articulation ( 36 ) of the first support ( 28 ), the table ( 20 ) comprises, at a lower part, a foot ( 44 ) that is oriented downward, at a level of a free end defining the axis of articulation ( 38 ) of the second support ( 30 ).

5. The protection and guide device according to claims 1 , wherein the first support includes a hinge.

6. The protection and guide device according to claims 5 , wherein the second support includes a hinge.

7. The protection and guide device according to claims 1 , wherein the first support is stationary.

8. The protection and guide device according to claims 1 , wherein the first support is stationary.

9. A device to protect and guide at least one cable connecting a direct-vision window of an aircraft cabin with a window support, said direct-vision window moves in a first translation direction, toward an inside of the cabin, to an intermediate position that is offset relative to the window support, and in a second release translation direction unblocking an opening, the device comprising:

a cable chain protecting and guiding said cable, the cable chain deforms along a winding plane when the direct-vision window moves;

a first articulable support for the direct-vision window pivoting on an articulation axis parallel to the second release direction, the first articulable support having a first edge to support the cable chain; and

a second articulable support for the window support pivoting on an articulation axis parallel to the second release direction, the second articulable support having a first edge to support the cable chain,

wherein when the direct-vision window moves in the second release translation direction a portion of the cable chain will flatten against the first edge of the first support or the first edge of the second support.

10. The protection and guide device according to claim 9 , wherein the cable chain includes a number of links connected two by two by axes of rotation that are parallel to one another.

11. The protection and guide device according to claim 9 , wherein the first support is connected to the window support.

12. The protection and guide device according to claim 9 , wherein the second support is connected to the direct-vision window.

13. The protection and guide device according to claim 9 , wherein the first support includes a hinge.

14. The protection and guide device according to claim 13 , wherein the second support includes a hinge.

15. The protection and guide device according to claim 14 , the window support includes a table, the table having a foot connect to the first support associated with the window support.

16. The protection and guide device according to claim 9 , wherein the direct-vision window includes a crankcase to protect the cable chain.

17. The protection and guide device according to claim 16 , wherein the crankcase includes a flange extending downward and connecting to the second support associated with the direct-vision window.

18. The protection and guide device according to claim 17 , the window support includes a table, the table having a foot connect to the first support associated with the window support.

19. A protection and guide device, comprising:

at least one cable connecting a direct-vision window of an aircraft cabin with a corresponding window support, the direct-vision window moveable in a first translation direction, toward an inside of the cabin, and in a second release translation direction to unblocking an opening;

a cable chain protecting and guiding the at least one cable, the cable chain deforms along a winding plane when the direct-vision window moves;

a first articulable support for the direct-vision window pivoting on an articulation axis parallel to the second release direction, the first articulable support having a first edge to support the cable chain; and

a second articulable support for the window support pivoting on an articulation axis parallel to the second release direction, the second articulable support having a first edge to support the cable chain,

wherein when the direct-vision window moves in the second release translation direction a portion of the cable chain will flatten against the first edge of the first support or the first edge of the second support.
