Abstract

For a seat group arrangement for a passenger cabin of an aircraft it is proposed to realize a temporary enlargement of the circulation area by widening the longitudinal aisle of the aircraft for the entry and exit period. For this purpose, a passenger seat group has a supporting frame which is provided with seat legs for fastening to the aircraft floor. At least one first fixedly secured seat having in each case a seat part and in each case a backrest and a further seat which is movable in the transverse direction and has a seat part and a backrest is provided on the supporting frame. The further seat is connected to the supporting frame via a folding device, and the folding device is configured to realize a change in width of the further seat in relation to the seat legs of the supporting frame.

First claim

1 . A seat group arrangement for a passenger cabin of an aircraft, with at least one passenger seat group having a supporting frame comprising seat legs for fastening to a floor of the aircraft, at least one first fixedly secured seat having in each case a seat part and in each case a backrest on the supporting frame, and a further seat which is movable in a transverse direction and has a seat part and a backrest, wherein the seat part of the further seat is connected to the supporting frame by a folding device, and the folding device is configured to have a change in width of the further seat in relation to the seat legs of the supporting frame.

2 . The seat group arrangement according to claim 1 , wherein the folding device in a first position holds the seat part of the further seat above a plane of the seat part of the first seat.

3 . The seat group arrangement according to claim 1 , wherein an upper part of the supporting frame comprises at least one supporting strut that can be adapted in length by a telescopic rod in a region of the further seat in a manner corresponding to the change in width.

4 . The seat group arrangement according to claim 1 , wherein the folding device has at least one spring element which holds the further seat part in an unloaded state in a first position above a plane of the seat part of the first seat, and in a loaded state the further seat part is positioned on the same plane as the seat part of the first seat.

5 . The seat group arrangement according to claim 1 , wherein the folding device has a lever system which, in operative connection with a sliding element, in a first position is configured to raise the seat part with respect to a plane of the first fixedly secured seat part and simultaneously provide a lateral offset of the seat part in relation to a second position or normal position.

6 . The seat group arrangement according to claim 1 , wherein the folding device has a lever system which, in operative connection with a sliding arrangement, in a normal position holds the further seat part in a same plane with respect to a plane of the first fixedly secured seat part and simultaneously, by lateral lowering of the further seat part, a normal seat width of the further seat can be reached.

7 . The seat group arrangement according to claim 1 , wherein an outer armrest support which faces a longitudinal aisle of the aircraft and has an armrest element is connected to at least one telescopic rod via at least one rod receptacle.

8 . The seat group arrangement according to claim 1 , wherein the backrest of the further seat can be displaced via displacement spindles for changing width of the further seat.

9 . A passenger seat group, having a supporting frame comprising seat legs for fastening to a floor, at least one first fixedly secured seat having in each case a seat part and in each case a backrest on the supporting frame, and a further seat which is movable in a transverse direction and has a seat part and a backrest, wherein the further seat is connected to the supporting frame by a folding device, and the folding device is configured to have a change in width of the further seat in relation to seat legs of the supporting frame.

10 . A passenger cabin for an aircraft, comprising:
at least one longitudinal aisle of the aircraft, wherein at least one cabin region comprises seat rows with fixedly secured passenger seat groups; and at least one cabin region comprising a seat group arrangement, the seat group arrangement comprising:
at least one passenger seat group having a supporting frame comprising seat legs for fastening to a floor of the aircraft, at least one first fixedly secured seat having in each case a seat part and in each case a backrest on the supporting frame, and a further seat which is movable in a transverse direction and has a seat part and a backrest, wherein the seat part of the further seat is connected to the supporting frame by a folding device, and the folding device is configured to have a change in width of the further seat in relation to the seat legs of the supporting frame.
