at least one seat fastening rail which can be installed in a cabin floor of the passenger aircraft and in which the seat supporting frame is mounted; a first electronic housing comprising electrical power converter components and which is mounted on the seat fastening rail; a second electronic housing in which electrical output ports for connecting electronic terminal devices are disposed; and wired cabling which electrically connects a supply port of the electrical power converter components of the first electronic housing to the electrical output ports of the second electronic housing. ### Claim 2 (depends on 1) The passenger seat arrangement according to claim 1, wherein the first electronic housing has a rail mounting adapter, and a vector of a weight force of the first electronic housing runs through the rail mounting adapter into the seat fastening rail. ### Claim 3 (depends on 1) The passenger seat arrangement according to claim 1, wherein the seat supporting frame has supporting feet for a seating surface of the at least one passenger seat. ### Claim 4 (depends on 3) The passenger seat arrangement according to claim 3, wherein the first electronic housing is fastened to a supporting foot of the seat supporting frame. ### Claim 5 (depends on 1) The passenger seat arrangement according to claim 1, wherein the electrical output ports of the second electronic housing comprise USB sockets, seat lighting ports of passenger seats, AC voltage ports and/or seat actuator ports. ### Claim 6 (depends on 1) A passenger aircraft comprising: a passenger cabin; at least one electrical energy source; and at least one passenger seat arrangement according to claim 1, the at least one seat fastening rail of which is mounted in the cabin floor of the passenger cabin, and the second electronic housing of which is respectively connected to the at least one electrical energy source via electrical supply lines running in or along the seat fastening rail. ### Claim 7 (depends on 6) The passenger aircraft according to claim 6, wherein a weight of the second electronic housing is less than 3% of a weight of the seat assembly. ### Claim 8 (depends on 6) The passenger aircraft according to claim 6, wherein the seat fastening rail runs in the cabin floor along a longitudinal axis of the passenger aircraft. ### Claim 9 (depends on 6) The passenger aircraft according to claim 6, wherein the passenger seat arrangement has at least two passenger seats arranged beside one another. ### Claim 10 (depends on 9) The passenger aircraft according to claim 9, wherein a seat fastening rail in the cabin floor is assigned to each of the at least two passenger seats arranged beside one another, and wherein the passenger seat arrangement has at least two separate first electronic housings in each of which electronic power converter components are arranged and which are mounted on different ones of the seat fastening rails assigned to the at least two passenger seats arranged beside one another. ### Claim 11 (depends on 6) The passenger aircraft according to claim 6, wherein the at least one first electronic housing has openings for passive air cooling of the electrical power converter components therein. ### Claim 12 A method for supplying energy to a passenger seat arrangement in a passenger aircraft, the method comprising: mounting a passenger seat assembly having at least one passenger seat and a seat supporting frame on at least one seat fastening rail which is installed in a cabin floor of the passenger aircraft; mounting a first electronic housing, in which electrical power converter components are arranged, on the at least one seat fastening rail; mounting a second electronic housing, which comprises electrical output ports for connecting electronic terminal devices, on the passenger seat assembly; and electrically connecting a supply port of the electrical power converter components of the first electronic housing to the electrical output ports of the second electronic housing via wired cabling. ### Claim 13 (depends on 12) The method according to claim 12, wherein a weight of the second electronic housing is less than 3% of a weight of the passenger seat assembly. ### Claim 14 (depends on 12) The method according to claim 12, wherein the seat supporting frame has supporting feet for a seating surface of the at least one passenger seat, and the mounting of the first electronic housing also comprises fastening the first electronic housing to a supporting foot of the seat supporting frame. ### Claim 15 (depends on 12) The method according to claim 12, wherein the first electronic housing has a rail mounting adapter, and a vector of a weight force of the first electronic housing runs through the rail mounting adapter into the seat fastening rail.
