System for adjusting the position of at least one seat component of a passenger seat and associated common control unit
First Claim
1. A system for adjusting the position of at least one seat component of a passenger seat in an ensemble of passenger seats, the system being installed in a cabin of an aircraft, wherein the passenger seats are each provided with at least one actuator for adjusting the position of the seat component, the system comprising:
- a plurality of seat controls, which are respectively mounted locally on the passenger seats, wherein each seat controloperates a corresponding one of the actuators,includes at least one operating element, by which a passenger can operate the corresponding seat control, andincludes at least one data transmission unit; and
a common control unit, which is installed in the aircraft and is common to the seat controls and includes at least one data transmission unit, provided for data transfer with the data transmission units of the seat controls, wherein the data transmission units of the seat controls and the at least one data transmission unit of the common control unit perform wireless data transfer between the common control unit and the seat controls, the data relating to a position of the at least one seat component and to operation of the actuators, and wherein the wireless data transfer is effected by radio waves.

17. A system for adjusting the position of at least one seat component of a passenger seat in an ensemble of passenger seats, the system being installed in an aircraft cabin, wherein the passenger seats are each provided with at least one actuator for adjusting the position of the seat component, the system comprising:
-
a plurality of seat controls, which are respectively mounted locally on the passenger seats, wherein each seat control operates a corresponding one of the actuators, includes at least one operating element, by which a passenger can operate the corresponding seat control, and includes at least one data transmission unit; and a common control unit, which is installed in the aircraft and is common to the plurality of seat controls and includes at least one data transmission unit, provided for data transfer with the data transmission units of the seat controls, wherein the data transmission units of the seat controls and the at least one data transmission unit of the common control unit perform wireless data transfer between the common control unit and the seat controls, wherein the data transmission unit of the common control unit has a plurality of elements for data receiving and data sending mounted so as to be spatially separated in the aircraft cabin for wireless reception of data from the seat controls of the passenger seats; and
the wireless data transfer is effected between one of the data receiving and data sending elements and a corresponding one of the seat controls by means of radio waves.

18. A system for adjusting the position of at least one seat component of a passenger seat in an ensemble of passenger seats, the system being installed in an aircraft cabin, wherein the passenger seats are each provided with at least one actuator for
adjusting the position of the seat component, the system comprising: -
a plurality of seat controls, which are respectively mounted locally on the passenger seats, wherein each seat control operates a corresponding one of the actuators, includes at least one operating element, by which a passenger can operate the corresponding seat control, and includes at least one data transmission unit; and a common control unit, which is installed in the aircraft and is common to the plurality of seat controls and includes at least one data transmission unit, provided for data transfer with the data transmission units of the seat controls, wherein the data transmission units of the seat controls and the at least one data transmission unit of the common control unit perform wireless data transfer between the common control unit and the seat controls, wherein the data transfer uses a time multiplexing transmission process in which a communication with the seat controls is effected respectively during time slots which are each reserved inside a time frame uniquely for a respective one of the seat controls, wherein the common control unit has a display device on which the data received from the seat controls and data to be sent to the seat controls may be displayed, and the display device displays the arrangement of several passenger seats in accordance with their actual arrangement in the aircraft and displays the current position of the seat components of at least one of the passenger seats, and wherein the display device marks aircraft passenger seats which are in an initial safety position prescribed for takeoff or landing and marks the other aircraft passenger seats in a different manner. - View Dependent Claims (19, 20)
