Aircraft flight deck comprising a folding seat
There is provided an aircraft folding seat, comprising a frame which pivots about a vertical axis and on which are mounted a seat-rest and a back-rest. The flight deck provided comprises control and/or viewing devices, at least one seat, an access door and a corridor for access to the at least one seat which is closed at its opposite end to the at least one seat by the access door. A folding seat is mounted in the corridor such that it can pivot and adopt a first position in which it closes the corridor so forming a lock enclosure with the access door and a folded back second position enabling access to the at least one seat from the corridor.
1. A flight deck of an aircraft, the flight deck comprising:
control and/or viewing devices;
at least one seat;
an access door; and
a corridor for access to the at least one seat, which is closed at an opposite end to the at least one seat by the access door;
a folding seat comprising a frame which pivots about a vertical axis and on which are mounted a seat-rest and a back-rest, the folding seat being mounted in the corridor such that the folding seat is configured to pivot and adopt a first position in which the folding seat closes the corridor so forming a lock enclosure with the access door and a second position in which the folding seat enables the access to the at least one seat from the corridor.
2. The aircraft flight deck according to claim 1 , wherein the folding seat is, in the second position, folded back against a member delimiting the corridor and is configured to adopt a third position pivoted through at least 135° relative to the second position.
3. The aircraft flight deck according to claim 1 , wherein the corridor comprises a floor in which is located a hatch door for access to a lower equipment zone, and the hatch door is located behind the folding seat when the folding seat is in the first position.
4. The aircraft flight deck according to claim 1 , wherein the corridor comprises a ceiling in which is located a hatch door for rescue and emergency evacuation, and the hatch door is located above the seat-rest when the folding seat is folded back against a member delimiting the corridor.
5. The aircraft flight deck according to claim 1 , wherein the corridor is delimited laterally by furniture.
6. The aircraft flight deck according to claim 5 , wherein at least one item of the furniture comprises a structural upright, such that the folding seat is pivotally mounted relative to the structural upright.
7. The aircraft flight deck according to claim 1 , wherein the folding seat comprises an armored sliding plate in each of a lower portion and an upper portion of the folding seat.
8. The aircraft flight deck according to claim 7 , wherein the folding seat in the first position closes the lock enclosure using the armored sliding plates.
9. The aircraft flight deck according to claim 1 , wherein a back face of the folding seat is reinforced to be resistant to impact of projectiles from a firearm.
10. The aircraft flight deck according to claim 1 , wherein the folding seat bears on a back face a ladder mounted via at least one four-bar linkage parallelogram, and wherein the back face of the folding seat opposes a face adapted to receive a user of the folding seat.
11. The aircraft flight deck according to claim 1 , wherein the folding seat is adjustable in height.
12. The aircraft flight deck according to claim 11 , wherein the folding seat is mounted on structural components of the flight deck via at least one intermediate member of profiled cross-section able to slide on the structural components bearing the folding seat.
13. The aircraft flight deck according to claim 1 , wherein the back-rest of the folding seat is tiltable.
14. An aircraft comprising a flight deck according to claim 1 .
