Description

Technical Field

[0001] The present invention relates to: a seat assembly for a passenger having a sensor data acquisition device having a plurality of sensors assigned to the seat assembly; a passenger aircraft having such a seat assembly; and a method for acquiring passenger-related sensor data in a passenger seat assembly in a passenger aircraft. Background Technology

[0002] Personal electronic devices (PEDs) are now ubiquitous. Normally, these PEDs are carried by the user during travel, even on airplanes. For passenger convenience, it is desirable to provide passengers with the possibility of charging the PED's power storage device or keeping the PED plugged in while on board. Airlines generally provide charging options for PEDs (such as laptops, mobile phones, smartphones, tablets, etc.), with either a USB port or a power outlet located at each passenger's respective seat.

[0003] For local power supply of electrical appliances on the aircraft (both fixed and portable devices, such as power devices for electrical devices), a locally installed power distribution system with power converters is used. Multiple electrical appliances with different power requirements can be connected to these power converters. For example, a power distribution system for seat groups in passenger aircraft can supply electrical power equally to the PEDs of all passengers in the seat group, for example, for plug-in operation of the PEDs and / or charging of energy storage devices.

Terms given regarding orientation, such as “up,” “down,” “left,” “right,” “above,” “below,” “horizontal,” “vertical,” “before,” “after,” and similar expressions, are for illustrative purposes only and are not intended to limit the generality to the specific design as shown in the drawings.

[0028] In the accompanying drawings, the same, functionally identical, and operational elements, features, and components (unless otherwise described in detail) are correspondingly provided with the same reference numerals. Detailed Implementation

[0029] In the context of this invention, Personal Electronic Devices (PEDs) include all electronic devices that can be used for entertainment, communication, and / or office purposes. For example, PEDs can include all types of terminal devices such as laptops, mobile phones, smartphones, handheld devices, PDAs, tablet PCs, GPS devices, navigation devices, audio devices such as MP3 players, portable DVDs, or... A media player or a digital camera.

[0030] In the context of this invention, passenger seats can include any form of structural component determined to accommodate passengers during the duration of the vehicle's operation. Passenger seats in aircraft can, in particular, be used individually and at least temporarily by passengers of the aircraft during flight. In the context of this invention, a seat or passenger seat can be an aircraft seat divided into seat assemblies, but can also be a recliner, armchair, bed, first-class or business-class suite, or similar seating furniture within the aircraft interior.

[0031] In the context of this invention, a power conversion component is any circuit or device that can be used to convert an input current type (DC or AC) to another corresponding current type, or to change characteristic parameters (such as voltage and frequency) of the input current type. A power conversion component may, for example, include a converter. Such a converter may include: a rectifier for converting AC current to DC current; an inverter for converting DC current to AC current; a converter for converting one type of AC current to another; or a DC-DC voltage converter for converting one type of DC current to another. In the context of this invention, a power conversion component may be implemented using analog components (such as resistors, inductors, and capacitors) and / or using semiconductor-based electronic structural elements (such as diodes, transistors, or thyristors).

[0032] Figure 1 A schematic structure of the passenger seat assembly 100 is shown in a side view. Figure 2 A schematic block diagram showing components of a passenger seat assembly 100 in a passenger aircraft and corresponding associated peripheral components. For example, the passenger seat assembly 100 may have passenger aircraft (e.g., in...) Figure 3 The passenger seat assembly 10 in the aircraft A is shown schematically. The passenger aircraft A may include various passenger seat assemblies that are fixedly or securely mounted in the passenger cabin, for example by one or more seat fastening rails 11 extending in the passenger cabin floor.

[0033] The passenger seat assembly 10 may have one or more passenger seats, which, for example, have a seating surface and a backrest hinged to the seating surface. Here, the passenger seats may be arranged side by side, i.e., having laterally adjacent seating surfaces, so that multiple passengers can simultaneously occupy the passenger seats of the passenger seat assembly 10.

[0034] The passenger seat assembly 10 may also have a seat support frame with front and rear outriggers that support and bear the seating surface. The seat support frame allows the passenger seat assembly 10 to be mounted onto one or more seat fastening rails 11 in the passenger compartment. Here, the seat fastening rails 11 may, for example, have an extension direction along the longitudinal axis of the passenger aircraft A in the cabin floor, and in the case of multiple seat fastening rails 11, these seat fastening rails extend particularly parallel to each other.

[0035] The power supply cables can extend in or along the seat fastening rails 11, and the electrical power source on the passenger aircraft A can be electrically connected to and supplied with power to the corresponding power supply system assigned to the passenger seat assembly 10 via these power supply cables.

[0036] Here, each passenger seat assembly 100 in passenger aircraft A may, for example, have a separate energy supply system locally assembled in passenger aircraft A. Here, the energy supply system may be constructed modularly, as exemplarily in… Figure 1 As shown in the diagram. The basic module of the corresponding energy supply system can be mounted on one of the seat fastening rails 11, while the associated peripheral modules of the energy supply system are mounted on suitable locations on the passenger seat assembly 10 for connecting power consumption devices. The energy supply system can be powered by one or more electrical energy sources (not explicitly shown) in the passenger aircraft A.

[0037] These electrical energy sources may, for example, have one or more AC voltage sources, such as generators, particularly engine generators or dynamic pressure turbine generators. Alternatively or otherwise, these electrical energy sources may include, for example, DC voltage sources, such as photovoltaic devices or fuel cells. These electrical energy sources can be electrically coupled to the corresponding basic module of the energy supply system via feeder wires extending in or along the seat fastening rail 11.

[0038] For example, the energy supply system can be used to supply permanently installed power consumption devices (such as displays of in-flight entertainment systems on passenger aircraft, seat lighting devices for passenger seats, seat actuators, and the like) as well as temporarily connected power consumption devices (such as PEDs, power banks, or similar power consumption devices assigned to one seat in the passenger seat assembly 100 and configured for use by passengers who have reserved the corresponding seats during their journey).

[0039] like Figure 1 and Figure 2 As shown, the power supply system is constructed in a modular manner, such that the base module has a first electronic device housing 5 in which power conversion components are arranged. The first electronic device housing 5 can be mounted on at least one of the seat fastening rails 11 (another mounting possibility), and it is also possible to mount it, for example, on the support frame of the passenger seat assembly 10.

[0040] The peripheral modules of the power supply system can be housed in a second electronic device housing 8, which is separate from the first electronic device housing 5. The first electronic device housing 5 may have a power supply interface 6, through which one or more second electronic device housings 8 can be electrically connected via feed lines 7 in the form of wired cables. Due to the separation between the first electronic device housing and the second electronic device housing 5 or 8 in the basic module and peripheral module, the second electronic device housing 8 can be arranged on the passenger seat assembly 10 from an ergonomic point of view.

[0041] The second electronic housing 8 houses electrical output interfaces for connecting electronic terminal devices (such as a passenger's PED). These electrical output interfaces may include, for example, a USB interface, a seat lighting interface for the passenger seat, an AC voltage interface, and / or a seat actuator interface. The power supply interface 6 of the power conversion component of the first electronic housing 5 is electrically connected to the electrical output interface of the second electronic housing 8 via a wired cable 7.

[0042] The electrical output interface in the second electronic device housing 8 can be, in particular, a USB interface that operates according to the USB power transfer specification and / or the USB battery charging specification. Therefore, power-consuming devices connected to these USB interfaces, such as the PEDs of passengers in aircraft A, can obtain electrical power from the power supply system.

[0043] An opening may be provided in the first electronic device housing 5 for passive air cooling of the power conversion components disposed therein. Alternatively or additionally, active cooling of the power conversion components within the first electronic device housing 5 may be achieved using a suitable cooling system.

[0044] In the immediate vicinity of the passenger seat assembly 100, the passenger seat assembly 10 has multiple sensors assigned to the respective passenger seat assembly 10, each of which is connected to a sensor data interface 9 of the first electronic housing 5 of the power supply system. For example, an optical sensor 1 may be provided, which can acquire optical signals, such as video recordings or other image data of the passenger seat and / or the passenger assigned to the passenger seat. A seat occupancy sensor 2 may, for example, measure the load on the seating surface to determine whether a passenger is in the seat and whether the passenger is moving. A seating position sensor 4 may, for example, be located in the backrest of the passenger seat to determine the backrest angle. Other sensors 3 (e.g., temperature sensors, current sensors, voltage sensors, motion sensors, and / or ultrasonic sensors) may also be provided, for example, in a passenger service device 12 arranged above the passenger seat assembly 10. Furthermore, it is possible to connect electrical sensors, such as voltage sensors and / or current sensors, to the electrical output interfaces (e.g., USB interface, passenger seat lighting interface, AC voltage interface, and / or seat actuator interface) of the second electronic device housing 8 to acquire time-resolved usage data from the USB interface, seat lighting interface, AC voltage interface, and / or seat actuator interface.

[0045] Sensor data collected by each of the sensors 1, 2, 3, and / or 4 can be fed into the first electronic device housing 5 via the sensor data interface 9. A sensor data processing device 5a is arranged in the first electronic device housing 5, which is designed to process the sensor data collected by sensors 1, 2, 3, and / or 4. After processing, the processed sensor data is forwarded to the central sensor data evaluation device 40 of the passenger aircraft A. Thus, the central sensor data evaluation device 40 of the passenger aircraft A can acquire and centrally evaluate the respective passenger-related sensor data from the individual passenger seat assemblies 100 distributed throughout the passenger aircraft.

[0046] In addition to the sensor data collected by the individual sensors 1, 2, 3, and / or 4, the sensor data processing apparatus 5a can also consider environmental data from the environment of the passenger aircraft A. For this purpose, environmental data from the environment of the passenger aircraft A can be received. This environmental data may include, for example, data about the geographical location of the passenger aircraft A, data about the ambient temperature of the passenger aircraft A, data about the departure point and / or destination of the passenger aircraft A, data about the predicted weather for the departure point and / or destination of the passenger aircraft A, and / or data about the local time of the passenger aircraft A. Here, the environmental data may, for example, come from the aviation server 20 on the passenger aircraft A and / or other environmental data sources 30 outside the passenger aircraft A, such as onboard servers or aviation servers of other passenger aircraft. The sensor data processing apparatus 5a acquires the environmental data, correlates the received environmental data with the collected sensor data in terms of location and time, and considers this correlation when processing the sensor data acquired by the sensors through the sensor data interface 9.

[0047] Figure 4 This illustrates a passenger seat assembly (e.g., combined) for use in passenger aircraft. Figure 1 and Figure 2 A flowchart illustrating the method steps of acquiring passenger-related sensor data in a passenger seat assembly 100 is provided. This is particularly relevant to passenger aircraft A (such as those with passenger seat assemblies 100). Figure 3 The execution method M is described above.

[0048] First, in the first step M1, passenger-related sensor data is acquired by assigning multiple sensors to the passenger seat assembly 10, which has at least one passenger seat. Such sensors may include, for example, optical sensors (such as cameras), seat occupancy sensors, seating position sensors, temperature sensors, current sensors, voltage sensors, motion sensors, and / or ultrasonic sensors. Optical sensors may be sensors mounted in the backrest or passenger service unit, which can continuously or at specific time intervals monitor the passenger's seating position, eye movements, or other physical characteristics. Current or voltage sensors may be provided to monitor the use of electrical output interfaces on the passenger seat assembly 10 for connecting electronic terminal devices (arranged in a second electronic device housing 8 of the power supply system). Seat occupancy sensors can monitor whether the passenger is sitting in their seat or whether and within what range the passenger is moving in their seat, so as to detect, for example, whether the passenger is sleeping. Seating position sensors may, for example, monitor the setting of the passenger seat backrest.

[0049] In step M2, the collected passenger-related sensor data can be transmitted via the sensor data interface 9 of the first electronic housing 5, which houses the power conversion components, in the power supply system assigned to the passenger seat assembly 10. In step M3, the collected sensor data can be processed by the sensor data processing device 5a of the power supply system. The sensor data processing device 5a may be, for example, a dedicated processor housed in the first electronic housing 5 and connected to the sensor data interface 9.

[0050] Optionally, in step M4, environmental data from the environment of passenger aircraft A may be received. This environmental data may include, for example, data regarding the geographical location of passenger aircraft A, data regarding the ambient temperature of passenger aircraft A, data regarding the departure point and / or destination of passenger aircraft A, data regarding the predicted weather for the departure point and / or destination of passenger aircraft A, and / or data regarding the local time of passenger aircraft A. Here, the environmental data may, for example, come from an aviation server 20 on passenger aircraft A and / or other environmental data sources 30 outside passenger aircraft A, such as an onboard server or an aviation server of another passenger aircraft. The sensor data processing device 5a acquires the environmental data, correlates the received environmental data with the acquired sensor data in terms of location and time, and takes into account this correlation when processing the sensor data acquired by the sensors through the sensor data interface 9.

[0051] Finally, in step M5, the sensor data processed by the sensor data processing device 5a, and processed further considering received environmental data when necessary, is forwarded to the central sensor data evaluation device 40 of the passenger aircraft A. For this purpose, the sensor data processing device 5a can be connected to the sensor data evaluation device 40 of the passenger aircraft A via a data cable extending in or along the seat fastening rail 11. Alternatively or additionally, wireless data transmission can also be performed from the respective sensor data processing device 5a of the passenger aircraft A to the sensor data evaluation device 40. The central sensor data evaluation device 40 can evaluate the sensor data collected by the sensor data processing device 5a and, based on this, provide passenger-related information to various other units on the passenger aircraft A. The central sensor data evaluation device 40 can, for example, be connected to one or more terminal devices 50 of the in-flight entertainment system of the passenger aircraft A, and, based on the evaluated sensor data, transmit passenger-related instructions for each passenger seat assembly 100 to the relevant terminal device 50 of the in-flight entertainment system.

[0052] By collecting sensor data and, when necessary, incorporating environmental data from the aircraft, appropriate evaluation algorithms (such as those based on artificial intelligence) can be used to draw conclusions about the needs and comfort levels of individual passengers. This allows for the provision of passenger-related comfort and services on passenger aircraft, making the passenger stay as pleasant as possible and personalizing the flight experience. Sensor data evaluations can directly generate tailored operational instructions, recommendations, or service suggestions for flight attendants. Furthermore, tips and suggestions to improve flight comfort can be provided to passengers on their personal devices or on in-flight entertainment systems.
