Abstract

A passenger seat arrangement for installation in an aircraft comprises at least one seating unit comprising a backrest element and a seat element pivotable relative to the backrest element between a resting position and a position of use. The passenger seat arrangement also has a support frame which bears against the at least one seating unit and which is able to be connected in a load-bearing manner to a structure of the aircraft. The support frame has at least one mechanical interface which, in each case, is assigned to a seating unit and is designed to fasten different mutually exchangeable modular units in a releasable and load-transmitting manner to the support frame.

First claim

1 . A passenger seat arrangement for installation in an aircraft, comprising:
at least one seating unit comprising a backrest element and a seat element which is pivotable relative to the backrest element between a resting position and a position of use; and a support frame which bears the at least one seating unit and which is configured to be connected in a load-bearing manner to a structure of the aircraft, wherein the support frame has at least one mechanical interface which is assigned to a seating unit and is configured to fasten different mutually exchangeable modular units in a releasable and load-transmitting manner to the support frame.

2 . The passenger seat arrangement according to claim 1 , wherein the seat element of the seating unit in its resting position faces the backrest element and bears thereagainst, and in its position of use is pivoted relative to the backrest element between an angle of 80° and 100°.

3 . The passenger seat arrangement according to claim 1 , wherein the support frame is configured to be connected in a load-transmitting manner to at least one of an aircraft cabin floor of a passenger cabin of the aircraft or a monument installed in the passenger cabin.

4 . The passenger arrangement according to claim 3 , wherein the support frame is configured to be connected to at least one of a seat rail of the aircraft or a side wall of the monument.

5 . The passenger seat arrangement according to claim 1 , wherein the support frame comprises at least two support elements which are configured to be connected in a load-transmitting manner to the structure of the aircraft and which pivotably mount at least one of the seat element or the backrest element of the seating unit.

6 . The passenger seat arrangement according to claim 5 , wherein the at least two support elements in each case comprise at least one of:
a connecting element configured to fasten the passenger seat arrangement in a load transmitting manner to a side wall of a monument installed in a passenger cabin; or a support foot configured to fasten the passenger seat arrangement in a load-transmitting manner to an aircraft cabin floor of the passenger cabin of the aircraft, wherein, in a state of the passenger seat arrangement installed in the aircraft, the support foot extends substantially transversely to the aircraft cabin floor.

7 . The passenger seat arrangement according to claim 6 , wherein, the support foot extends parallel to the side wall of the monument.

8 . The passenger seat arrangement according to claim 1 , wherein in a state of the passenger seat arrangement as installed in the aircraft, the mechanical interface is accessible in the resting position of the seat element below the seat element and in the position of use of the seat element, the mechanical interface is accessible above the seat element.

9 . The passenger seat arrangement according to claim 8 , wherein in the position of use of the seat element, the mechanical interface is accessible via a region arranged between the seat element and the backrest element.

10 . The passenger seat arrangement according to claim 1 , wherein the mechanical interface is an Isofix interface for an Isofix connection between the support frame and the different mutually exchangeable modular units.

11 . The passenger seat arrangement according to claim 1 , wherein the mechanical interface comprises at least one first latching element configured to be releasably latched to a complementary second latching element attached to the different mutually exchangeable modular units to fasten one of the different mutually exchangeable modular units in a load-transmitting manner to the support frame.

12 . The passenger seat arrangement according to claim 11 , wherein the first latching element is configured as a retaining bracket, to which a latching arm which is attached to the different mutually exchangeable modular units, is able to be latched.

13 . The passenger seat arrangement according to claim 12 , wherein the retaining bracket comprises an Isofix retaining bracket fixedly attached to the support frame and the latching arm comprises an Isofix latching arm forming the second latching element.

14 . A passenger seat system comprising:
a passenger seat arrangement according to claim 1 , and at least one modular unit fastened to the support frame of the passenger seat arrangement in a releasable and load-transmitting manner and exchangeable for a different modular unit.

15 . The passenger seat system according to claim 14 , wherein the at least one modular unit is at least one of a child restraint system, a wheelchair or a transport box for animals.

16 . The passenger seat system according to claim 14 , wherein the at least one modular unit comprises:
at least one first modular unit which is fastened to the support frame of the passenger seat arrangement in a state in which the seat element is pivoted in its position of use, so that the first modular unit is arranged on the seat element; or at least one second modular unit which is fastened to the support frame of the passenger seat arrangement in a state in which the seat element is pivoted in its resting position so that in a mounted state the second modular unit is arranged in a region in front of the seat element and the backrest element.

17 . The passenger seat system according to claim 16 , wherein the at least one first modular unit comprises a child restraint system.

18 . The passenger seat system according to claim 16 , wherein the at least one second modular unit comprises at least one of a wheelchair or a transport box for animals.

19 . An aircraft cabin region having a passenger seat arrangement according to claim 1 , which is connected in a load-transmitting manner via the support frame to an aircraft cabin floor.

20 . The aircraft cabin region according to claim 19 , which further comprises a monument with a side wall to which the passenger seat arrangement is connected in a load-transmitting manner via the support frame.
