Passenger seat system
A passenger seat system includes a backrest and a seat, which has a first sub-portion having a first surface and a second, opposite surface to the first surface as well as a second sub-portion having a first surface and a second, opposite surface to the first surface. The sub-portions are relatively movable in order to provide first and second operating positions. In the first operating position the sub-portions are positioned in relation to the backrest one behind the other such that the first surface of the first sub-portion and the first surface of the second sub-portion form a usable total seat surface. In the second operating position the sub-portions are positioned in relation to the backrest one above the other such that one of the surfaces of the first sub-portion or the first surface of the second sub-portion forms a usable partial seat surface.
1. Passenger seat system comprising:
a backrest and
a seat, which comprises a first sub-portion having a first surface and a second, opposite surface to the first surface as well as a second sub-portion having a first surface and a second, opposite surface to the first surface, wherein the first sub-portion and the second sub-portion are movable relative to one another in order to adjust the seat between a first and a second operating position, and wherein the first sub-portion and the second sub-portion in the first operating position of the seat are positioned in relation to the backrest one behind the other in such a way that the first surface of the first sub-portion and the first surface of the second sub-portion form a usable total seat surface,
wherein the first sub-portion and the second sub-portion in the second operating position of the seat are positioned in relation to the backrest one above the other in such a way that the first surface of the first sub-portion or the first surface of the second sub-portion forms a usable partial seat surface and the other one of the first surface of the first sub-portion or the other one of the first surface of the second sub-portion does not form a usable partial seat surface,
wherein the first sub-portion or the second sub-portion is configured to move substantially longitudinally along a longitudinal axis of the backrest to enable the first sub-portion to be displaceable substantially parallel to the second sub-portion in the direction toward the backrest so that, in the second operating position, the second surface opposite the first surface forming a usable partial seat surface of the first or the second sub-portion rests on the first surface of the other sub-portion not forming a usable seat surface.
2. Passenger seat system according to claim 1 ,
wherein the first sub-portion of the seat is provided with a seat cushion both in the region of its first surface and in the region of its second surface.
3. Passenger seat system according to claim 1 ,
further comprising a drive mechanism that is adapted to adjust the seat between the first and the second operating position thereof.
4. Passenger seat system according to claim 1 ,
further comprising a locking mechanism that is adapted to lock the seat in at least one of the first and the second operating position thereof.
5. Passenger seat system according to claim 1 ,
further comprising a biasing mechanism that is adapted to bias the seat into at least one of the first and the second operating position thereof.
6. Passenger seat system according to claim 1 ,
further comprising at least one armrest that is positionable in various positions along the longitudinal axis of the backrest.
7. Passenger seat system according to claim 6 ,
wherein an arm support of the armrest is fastened to the passenger seat system by a fastening device, which is displaceable relative to a receiving device of the passenger seat system and lockable in various positions in the receiving device.
8. Passenger seat system according to claim 7 ,
wherein the arm support of the armrest comprises a first portion and a second portion, wherein the first portion is pivotable about a first axis relative to the second portion and the second portion is pivotable about a second axis relative to the fastening device for fastening the atm support to the passenger seat system.
9. Passenger seat system according to claim 1 ,
wherein at least one of the first sub-portion and the second sub-portion of the seat is provided with at least one seat cushion that contains at least one of fibres, which are integrated into a matrix of a binding material, and woven fibres.
10. Aircraft comprising a passenger seat system according to claim 1 .
