Abstract

A cabin attendant seat comprises a seat element and a backrest. The backrest is movable relative to the seat element between an upright position, wherein a backrest surface of the backrest extends at an angle of approximately 80 to 100° relative to a seat surface of the seat element, and a folded-back position, wherein the backrest surface of the backrest extends substantially co-planar with the seat surface of the seat element.

First claim

The invention claimed is:

1. A cabin attendant seat comprising:
a seat element,
a backrest, said backrest being movable relative to the seat element between an upright position, wherein a backrest surface of the backrest extends at an angle of approximately 80 to 100° relative to a seat surface of the seat element, and a folded-back position, wherein the backrest surface of the backrest extends substantially co-planar with the seat surface of the seat element, and
a first pivoting mechanism allowing the cabin attendant seat to be pivoted between a stowed position and an operating position, wherein the cabin attendant seat is positionable relative to an aircraft monument into the stowed position by pivoting the seat element via the first pivoting mechanism such that the seat surface of the seat element faces a first wall of the aircraft monument and the backrest surface of the backrest faces a second wall of the aircraft monument, the second wall extending substantially perpendicular to the first wall, and wherein the cabin attendant seat is positionable relative to the aircraft monument into the operating position by pivoting the seat element via the first pivoting mechanism such that the seat surface of the seat element extends substantially perpendicular to both the first and the second wall of the aircraft monument and the backrest surface of the backrest is in the upright position.

2. The cabin attendant seat according to claim 1 , further comprising a footrest which is movable relative to the seat element between a stowed position, wherein the footrest does not extend beyond a front edge of the seat element and an extended position, wherein a supporting surface of the footrest extends substantially co-planar with the seat surface of the seat element.

3. The cabin attendant seat according to claim 2 , wherein the footrest comprises a first portion which, in the extended position of the footrest, is disposed adjacent to the seat element and a second portion which, in the extended position of the footrest, is disposed adjacent to the first portion, the first and the second portion of the footrest being movable relative to each other in a telescoping manner.

4. The cabin attendant seat according to claim 1 , further comprising a first locking mechanism which is adapted to lock the backrest in either its upright position or its folded-back position.

5. The cabin attendant seat according to claim 1 , wherein, in the stowed position of the cabin attendant seat, the backrest is disposed in its upright position relative to the seat element.

6. The cabin attendant seat according to claim 1 , further comprising at least one of:
a biasing mechanism which is adapted to bias the cabin attendant seat in its stowed position,
a second locking mechanism which is adapted to lock the cabin attendant seat in its operating position, and
a manually acuatable activating device which is adapted to manually activate the second locking mechanism when the cabin attendant seat is intended to be used with the backrest being disposed in its folded-back position.

7. The cabin attendant seat according to claim 1 , further comprising at least one of:
a headrest formed integral with the backrest, and
a support panel which is attached to a rear surface of the backrest and which is pivotable relative to the backrest between a stowed position, wherein the support panel extends substantially parallel to the backrest, and a support position, wherein the support panel extends substantially perpendicular to the backrest so as to form a supporting base for the backrest when the backrest is disposed in its folded-back position.

8. The cabin attendant seat according to claim 1 , further comprising:
a further seat element which is movable relative to the backrest between a folded position, wherein a seat surface of the further seat element extends substantially parallel to and faces the rear surface of the backrest, and an unfolded position, wherein the seat surface of the further seat element extends substantially perpendicular to the rear surface of the backrest.

9. The cabin attendant seat according to claim 1 , further comprising:
a second locking mechanism which is adapted to lock the cabin attendant seat in its operating position, and
an automatic activation device which is adapted to automatically activate the second locking mechanism when the cabin attendant seat is in use with the backrest being disposed in its upright position, and which is adapted to automatically release the second locking mechanism when the cabin attendant seat is not in use with the backrest being disposed in its upright position.

10. The cabin attendant seat according to claim 9 ,
further comprising at least one of:
a first restraint system which is adapted to restrain a user using the cabin attendant seat with the backrest being disposed in its upright position, wherein the automatic activation device for automatically activating and releasing the second locking mechanism preferably is coupled to the first restraint system, and
a second restraint system which is adapted to be restrain a user using the cabin attendant seat with the backrest being disposed in its folded-back position.

11. An aircraft monument comprising,
a first wall,
a second wall extending substantially perpendicular to the first wall, and
a cabin attendant seat comprising:
a seat element, and
a backrest, said backrest being movable relative to the seat element between an upright position, wherein a backrest surface of the backrest extends at an angle of approximately 80 to 100° relative to a seat surface of the seat element, and a folded-back position, wherein the backrest surface of the backrest extends substantially co-planar with the seat surface of the seat element,
the cabin attendant seat being attached to the first wall of the aircraft monument, the cabin attendant seat further comprising:
a first pivoting mechanism allowing the cabin attendant seat to be pivoted between a stowed position and an operating position, wherein the cabin attendant seat is positionable relative to the first and the second wall into the stowed position by pivoting the seat element via the first pivoting mechanism such that the seat surface of the seat element faces the first wall of the aircraft monument and the backrest surface of the backrest faces the second wall of the aircraft monument, and wherein the cabin attendant seat is positionable relative to the first and second wall into the operating position by pivoting the seat element via the first pivoting mechanism such that the seat surface of the seat element extends substantially perpendicular to both the first and second wall, and the backrest surface of the backrest is in its upright position.

12. The aircraft monument according to claim 11 , further comprising a stowage box which is fastened to the first wall of the aircraft monument in such a position that the seat element of the cabin attendant seat is supported by the stowage box when the cabin attendant seat is disposed in its operating position.

13. The aircraft monument according to claim 12 , wherein a recess is formed in the first wall of the aircraft monument, the recess being adapted to at least partially receive at least one of the seat element of the cabin attendant seat when the cabin attendant seat is disposed in its stowed position and the stowage box fastened to the first wall of the aircraft monument.

14. The aircraft monument according to claim 11 , further comprising at least one of:
a medical panel comprising at least one medical outlet, the medical panel being attached to the first wall of the a
