Description

[0001] System for operating seats with air conditioning

[0002] The invention relates to a system for operating seats with climate control. This system can be used, for example, in sports venues (such as stadiums) and event venues (such as concert halls or theaters). The system provides an air conditioning function for spectators in their seats. This air conditioning function is, in particular, a heating function.

[0003] In general, especially in venues where the spectator area is outdoors, there is an interest in offering visitors a high level of comfort. For example, it is often very cold in football stadiums during the winter. Heated seats would therefore be highly desirable.

[0004] However, the cost is a significant argument against offering such a function.

[0005] For example, seats in football stadiums are typically simple shell seats, often made of plastic. The unit cost of such seats is relatively low. Seats with built-in heating would incur significantly higher costs. Another problem is that the more complex the design of seats, the more susceptible they become to damage and potentially vandalism.

[0006] Furthermore, a heating function would incur significant energy costs during operation. For example, if a typical football stadium has 20,000 seats and were equipped with heated seats, with each heated seat activated, this would result in a considerable electrical power requirement. This would be particularly true if the seats in the football stadium are located outdoors and directly exposed to the elements. Against this background, the object of the present invention is to at least partially solve the problems described with reference to the prior art. In particular, a particularly advantageous system for providing seats with an air-conditioning function for sports and event venues is proposed.

[0007] This problem is solved by the invention according to the features of the independent claims. Further advantageous embodiments are specified in the dependent claims, as well as in the description and, in particular, in the description of the figures. It should be noted that the person skilled in the art can combine the individual features presented in a technologically meaningful way and thereby arrive at further embodiments of the invention.

[0008] The invention relates to a system comprising a plurality of seats, each having at least one electric temperature control device, wherein the seats each have control units or wherein a control unit is assigned to a group of seats, which is configured to receive control signals via a supply line and further to activate and / or deactivate the electric temperature control device in response to such control signals, wherein the seats are connected to at least one common supply line, wherein the system further comprises a control device which is connected to the supply line and is configured to communicate with a bus system with control units of the seats via the supply line, wherein an identifier readable by a mobile device is visibly arranged on each seat, with which the seat can be uniquely identified for software.

[0009] This system enables the easy installation of temperature-controlled seats in sports and event venues. While seat temperature control can generally include heating and / or cooling functions, a heating function is preferred here, as it significantly improves user comfort, especially in winter when seats are located outdoors. Multiple seats (e.g., an entire row) can be connected to a single power supply line, which provides electricity to operate the temperature control system. This eliminates the need for additional data lines to the seats. Preferably, each seat has exactly one connection for a power supply line and no further electrical connections for data lines, for example.Each seat has a control unit capable of selectively activating and / or deactivating the seat's temperature control system in response to control commands supplied via the power supply line. The control units preferably each include receivers that can receive signals modulated onto the current flowing through the power supply line. Furthermore, each control unit preferably includes a switch that allows the current supplied via the power supply line to be selectively applied to the temperature control system of the respective seat. The control unit preferably serves to modulate the control commands, originating from a central instance (e.g., a central server), onto the current flowing through the power supply line.

[0010] Control units are preferably integrated into the seat shells. A chamber is particularly preferably provided on the underside of the seat shells, in which a control unit is arranged.

[0011] In a previously described embodiment of the system, it is also possible for a group of seats to share a common control unit. In such an arrangement, individual power supply lines must run from the common control unit to the seats or their temperature control devices. The control unit preferably activates and deactivates the seat temperature control devices. The control unit preferably includes switches that can connect and / or disconnect the power supply to the respective seats. If a (common) control unit is provided for a group of seats, individual wiring for the seats or their temperature control devices is required, extending from this (common) control unit. Preferably, the control units and the control device are configured for communication via a DALI bus. DALI stands for "Digital Addressable Lighting Interface".A DALI bus can transmit data signals over a power line. Up to 64 addresses can be controlled via a DALI bus, preferably from a control device. These 64 addresses could, for example, be 64 different addresses of 64 different control units in 64 different seats. If the system described here is used in a football stadium, the system could, for example, encompass individual rows of seats in a seating block. A control device is configured, for example, to control the temperature control units in the seats of a row within a seating block. Typical seating blocks in football stadiums have, for example, 40 rows with 30 seats each. These 30 seats, or rather their temperature control units, can be controlled via 64 addresses of a DALI bus. Each row of a seating block can form a system with one control device and the 30 seats in that row.

[0012] The system described here allows for the very efficient provision of temperature-controlled seats and, in particular, heated seats.

[0013] The system is particularly preferred if it includes a server that is connected to the control device via a network connection, wherein the server provides a booking system with which a temperature control for a seat can be booked, and wherein the server is configured to transmit control signals to control units of the seats via the control device depending on bookings in the booking system.

[0014] Furthermore, it is preferred if the booking system provided by the server is configured to communicate with mobile devices and execute booking requests for seats identified by a mobile device via the readable identifier. The server or booking system can provide a web interface that can be operated with a browser on the mobile device to book a seat or the temperature control function of a seat. In other embodiments (alternatively or additionally), the server or booking system can also be configured to communicate with an application running on a mobile device to book a seat or the temperature control function of a seat.

[0015] In preferred embodiments, the server with the booking system is operated outside the sports or event venue where the system's temperature-controlled seats are located. The server and the control unit are preferably connected via the internet. The server is preferably connected to a plurality of control units, each configured to control a specific number of seats or their temperature control devices. Optionally, intermediate control units can be arranged between the server and the control units that transmit control commands for the seats or temperature control devices to the power supply lines. These intermediate control units translate control signals issued by the server or by a booking system running on the server and transmit them to the control unit described above.

[0016] A data connection between the server and the control devices can, for example, include (at least partially) a LAN or WAN. In particular, the data connection can also include a LoRaWAN connection [LoRaWAN = Long Range Wide Area Network]. This allows software on a central component (the server) to address each bus and each seat connected to a bus, or its control unit, and to individually switch the temperature control unit on or off in each seat.

[0017] The server can be its own physical hardware. It can also be virtual hardware. In principle, the server can be operated in any location within a data center. The booking system or business logic runs as software on the server. This software can be a web application.

[0018] The booking system can, in particular, be part of a business logic that is operated on the server to manage the temperature-controlled seats.

[0019] Such a business logic and booking system allows for the provision of temperature-controlled (especially heated) seats to users in a sports or event venue. The business logic and booking system also ideally facilitate billing for the seat heating. Users can book the heating function individually. Prices for the heating function can be individually set by the business logic. Higher prices for the heating function may be charged during periods of high electricity prices compared to periods of low electricity prices. A variety of pricing models are possible.

[0020] It is particularly preferred if the temperature control device is an electric heater.

[0021] Electric heaters can be integrated into seats cost-effectively. They can be powered by electricity via the mains power supply. The electrical energy is converted into heat within the heater.

[0022] Furthermore, it is preferred if the temperature control device is a cooling device.

[0023] A cooling system, also known as a temperature control system, can be implemented using Peltier elements. These elements function like small heat pumps. When an electric current is applied to the Peltier elements, heat is transferred from one side of the elements to the other. This results in cooling on one side of the Peltier elements. In other configurations, a cooling system can also function as a ventilation system. Such a system can, for example, include at least one fan that creates a flow of cooling air across the seat surface.

[0024] It is particularly preferred if the at least one temperature control device of a seat has a temperature control area of ​​between 200 cm² 2 and 2,000 cm 2 covers one of the seat surfaces.

[0025] Preferably, approximately 15% to 65% of the total surface area of ​​the seat is temperature-controlled and, in particular, heated. It has been found that for a comfortable user experience, such a proportion of the seat's surface is sufficient to provide temperature control. This is especially true if the temperature control system includes a heating element.

[0026] The temperature control device is particularly preferred as a heater, and the total heating power of all electric heating elements of a seat is between 20 watts and 50 watts, especially approximately 40 watts.

[0027] Such heating output is sufficient for a user of the seat to maintain a very comfortable seating experience even in winter.

[0028] Furthermore, it is preferred if at least one of the following positions of the system seats has a heating element:

[0029] - in or on a seat surface of the seats;

[0030] - in or on a backrest surface of the seats.

[0031] It is also preferred that a first heating element is arranged in or on a seat surface of the system's seat, and that a further heating element is arranged in or on a backrest surface of the system's seats. Preferably, the heating element in the seat surface covers an area of ​​approximately 30 by 30 centimeters. More preferably, the heating element in the backrest surface covers an area of ​​approximately 20 by 30 centimeters. The heating element in the backrest surface is particularly located in a lower region of the backrest surface. In this region, the contact of a user of the seat with the backrest surface is normally more intensive than in an upper region.

[0032] Furthermore, it is preferred if an identifier readable by a mobile device is visibly arranged on each seat of the system, with which the seat can be uniquely identified for a software.

[0033] Such a readable identifier can be, in particular, a QR code that can be scanned with the camera of a mobile device. Alternatively, it can be an RFID tag (possibly not visible from the outside) attached to the seat. In principle, various technologies can be used for the identifier. The identifier serves the purpose of informing a booking system which seat the respective user wishes to book the temperature control function for. The user of a seat can identify the identifier located on the seat with a mobile device (e.g., a smartphone). Preferably, the system is set up so that the user can book the temperature control function for a specific period of time via an interface (e.g., on a website or in an app). The website or app can be hosted on the server.

[0034] In principle, the booking system allows each individual seat to be addressed and its respective temperature control function to be activated and deactivated. It is also possible, in alternative operating modes, to activate entire rows or groups of seats without bookings via the booking system. One application for such a function could be, for example, melting snow on seats equipped with a temperature control function that functions as heating. Furthermore, the control units are specifically designed to regularly activate and deactivate the power supply to the seat in order to maintain a predefined heating output for at least one heating element of the electric heater.

[0035] Such an operating mode preferably involves PWM modulation of the current supplied to the heater. This allows the heater to operate in partial load mode.

[0036] This document also describes a procedure for operating a described system comprising the following steps: a) Identifying a seat using an attached identifier with a mobile device; b) Booking the heating of the seat identified in step a) via a server, whereby payment is made for activating the heating; c) Sending the activation command from the server to the seat; and d) Heating the seat according to the booking made in step b).

[0037] It should be noted that the special advantages and design features described above are also applicable and transferable to the method described below.

[0038] The invention and its technical context are explained in more detail below with reference to the figures. The figures show preferred embodiments, to which the invention is not limited. It should be noted in particular that the figures, and especially the size relationships shown in the figures, are only schematic. It should further be noted that features shown in the figures can also be omitted and / or supplemented or substituted with features from other figures. Figure 1 shows an exemplary three-dimensional view of a described seat;

[0045] Fig. 8: a flowchart of a procedure according to which the system shown in Fig. 7 can be operated.

[0046] Figure 1 shows an example of a described seat 1 in a three-dimensional view. The seat 1 preferably has a seat surface 12, which is particularly preferably concave in shape to offer the user of the seat 1 good seating comfort. The seat 1 also preferably has a backrest surface 13 against which the user of the seat 1 can lean. The seat 1 is typically formed by a seat shell 2. The seat shell is preferably made entirely of plastic. The seat 1 is preferably highly optimized for its application – for example, for use in a sports stadium. Mounting points 27 are shown here, for example, at which the seat shell 2 can be mounted on a support alongside a plurality of other seat shells 2 to form a row of seats.In preferred embodiments, the seat 1 can be quickly dismantled, for example, because a stadium can be reconfigured to offer more or fewer seats and / or to convert a standing area into a seating area and vice versa. A drainage structure 26, designed as a notch or indentation in the seat surface 12, is shown further. In particular, if the seat surface 12 is concave and forms a seat depression 32, water could collect on the seat surface 12 when it rains. The drainage structure 26 allows such water to drain away. The drainage structure 26 is particularly advantageous when the seat 1 is used outdoors, as is often the case with seats 1 in sports stadiums. An identifier 15 is preferably arranged on the seat 1, which can be used to identify the seat 1.The identifier 15 is preferably designed to be read by a mobile device. The identifier 15 can, for example, be a visible, readable QR code in which a unique identifier for seat 1 is integrated, with which seat 1 and, in particular, a heating element 3 of the seat can be activated.

[0047] Figure 2 schematically shows the seat 1 from Figure 1 in a sectional view with some optional additional features. The seat 1, or rather the seat shell 2, is shown in section 2, such that the seat surface 12 and the backrest surface 13 are cut away. A heater 3 is integrated into the seat 1. Here, the heater 3 is designed with heating elements 3 that are embedded in receiving areas 5 of the main material of the seat shell 2. Various ways in which the heater 3 is integrated into the seat are possible and feasible. In some embodiments, the receiving areas 5 in the seat shell 2 can, for example, be provided as recesses. The heating elements 4 can then be subsequently integrated into the receiving areas 5. If the heating elements 4 are made of an electrically conductive plastic, for example, then this electrically conductive plastic can be injected into the receiving areas 5 to form the heating elements 4.Current-energizing structures for energizing the electrically conductive plastic, not shown here, may have been previously inserted into the receiving areas 5 and then overmolded with the electrically conductive plastic. In other embodiments, it is also possible that the heating elements 4 of the heater 3 are placed in an injection mold for producing the seat shell 2 before the material of the seat shell 2 is placed in the injection mold.

[0048] The heater 3 or heating elements 4 are preferably integrated into the seat 1 such that both a seat surface 12 of the seat 1 and a backrest surface 13 of the seat can be heated by the heater 3. Particularly preferably, the heater 3 or heating elements 4 are positioned close to a surface of the seat surface 12 or the backrest surface 13, so that the best possible contact and heat transfer from the heater 3 to the user is achieved when the user is seated.

[0049] The seat 1 or seat shell 2 typically also has an underside 7 facing away from the seat surface 12 and a rear side 8 facing away from the backrest surface 13. In the embodiment shown in Fig. 2, an insulating structure 9 is arranged on the underside 7 and on the rear side 8. This insulating structure 9 can, for example, be made of a foam-like material and / or a windshield, which prevents heat dissipation from the heat produced by the heater 3 via the underside 7 or the rear side 8.

[0050] As also shown in Fig. 2, a cover layer 31 can be arranged on the heating element 3. The cover layer 31 impairs the heat transfer from the heating element to a user sitting on the seat 1 as little as possible. The cover layer 31 preferably serves to protect the heating element 3 and / or to provide electrical insulation for the heating element 3. Such a cover layer 31 is shown by way of example only in Fig. 2. It can be provided in all embodiments of a seat 1 according to Figs. 3 to 6.

[0051] Figure 2 illustrates that the seat 1 has a control unit 16, which is configured to selectively supply power to (activate) the seat's heater 3 or to interrupt the power supply to the heater 3. The control unit 16 is preferably connected to a power supply line 17, which can supply power to the seat 1 or the heater 3. The control unit 16 is further preferably able to receive and process activation and deactivation commands for the heater 3 via the power supply line 17 in order to activate and / or deactivate the heater 3. The control unit 16 thus preferably acts like a controllable switch. In particularly preferred embodiments, the control unit 16 can also operate the heater 3 at different intensities.In particular, the control unit 16 can be configured to regularly activate and deactivate the heater 3 in a PWM-like operation (PWM = pulse width modulation) in order to provide a reduced heating output from the heater 3. The arrangement of the control unit 16 in Fig. 2 is only exemplary. The control unit 16 can also be arranged differently (in particular, outside the seat 1). The design of the control unit 16 can also be applied to the embodiments shown in the other figures (in particular Figs. 3 to 6).

[0052] The power supply line 17 is preferably connected to the seat 1 via a plug connection 33. The plug connection 33 can preferably be disconnected when the seat 1 is removed. This allows for faster assembly and disassembly of the seat 1, even though an electrical connection to the power supply line 17 must be established for each individual seat 1.

[0053] Figure 3 shows an example of how the heating element 3 of the seat 1 can be constructed. The embodiment shown in Figure 3 can also be designed according to the sectional view shown in Figure 2. Section AA, which corresponds to Figure 3, is shown in Figure 2. The seat surface 12 of the seat is shown in Figure 2. The features shown in Figure 3 can be transferred to the backrest surface of the seat, which can be designed accordingly.

[0054] The heating element 4, or heating component 3, is made of an electrically conductive plastic and is located in a receiving area 5 of the seat shell 2. The heating element 4 spans a heating surface 11. Current-conducting structures 10 are integrated into the electrically conductive plastic of the heating element 4, through which the electrically conductive plastic of the heating element 4 can be supplied with an electric current. The current-conducting structures 10 are preferably made of metal. Preferably, there are two current-conducting structures 10, configured as interlocking combs. An electrical voltage is preferably applied between the current-conducting structures 10 to supply the electrically conductive plastic of the heating element 4 with an electric current. The electric current is converted into heat in the electrically conductive plastic of the heating element 4.

[0055] Figure 4 shows an alternative embodiment of the heating element 4. Also shown is the seat surface 2 of the seat 1, on which the heating element 4 spans a heating area 11. Here, the heating element 4 is designed as a resistive conductor 28 through which an electric current can flow. The electric current is converted into heat by or within the resistive conductor.

[0056] Figures 5 and 6 each show further embodiments of the seat in a sectional view. The sectional view in Figures 5 and 6 corresponds to the sectional view in Figure 2.

[0057] As shown in Fig. 5, the seat surface 12 is concave. The concave shape of the seat surface 12 can be present in the section through the seat 1 shown in Fig. 5, and also in another section through the seat 1 oriented perpendicular to it. The concave shape can thus form a kind of seat depression 32. This increases the seating comfort for a user of the seat. The heating element 4 is designed as a heating film 30, which is attached to the seat surface 12 and to the backrest surface 13. The heating film 30 can also be made of an electrically conductive plastic and be designed with current-enhancing structures (not shown here), the structure of which essentially corresponds to the structure of the current-enhancing structures according to Fig. 2 (interlocking combs). The heating film can be two-dimensionally curved and adapted to the shape of a concave seat surface 12 (to the seat depression 32). Not shown here is a top layer on the heating element 3, as shown in Fig.2 is shown. However, such a top layer can also be provided on the heating element 3.

[0058] According to the embodiment shown in Fig. 6, the heating elements 4 of the heater 3 are designed with resistance conductor tracks 28. The embodiment shown in Fig. 6 corresponds essentially to the embodiment shown in Fig. 3. Not shown here is a cover layer on the heater 3, as shown in Fig. 2. However, such a cover layer on the heater 3 can be provided additionally. An insulating structure 9 on the underside 7 and on the back 8 of the seat shell 2 is shown here by way of example.

[0059] Figure 7 schematically shows the described system 18 comprising described seats 1. The system typically has a plurality of seats, arranged, for example, in the form of rows of seats for spectators in a sports venue. Each seat has at least one electric temperature control device 3, which may in particular be a heater 3. A control unit 16 is integrated into each seat 1. In other embodiments, one control unit 16 is provided for a group of seats 1, or the control unit 16 is assigned to the group of seats 1. The seats 1 or the temperature control devices 3 / heaters 3 of the seats 1 are connected to a power supply line 17. Control signals can also be sent to the seats 1 or to the control units 16 of the seats 1 via the power supply line 17. The control units 16 preferably comprise controllable switches.These controllable switches are controlled by control signals transmitted via the supply line 17. The control signals can be modulated onto the current transmitted via the supply line. A voltage is preferably permanently supplied to the seats 1 via the supply line 17. Activation and deactivation signals for the temperature control unit 3 / heating 3 of specific seats 1 can preferably be transmitted via the supply line 17. These activation and deactivation signals are then preferably received by the control units 16 of all seats, but only evaluated by the seats for which the respective activation and deactivation signals apply. The activation and deactivation signals preferably contain an address for the respective seat 1 to be addressed and the actual control command (e.g.,Activation signal and / or deactivation signal). In response to such control signals, activation and / or deactivation of the electric temperature control unit 3 / heating 3 of the seats can be carried out.

[0060] System 18 preferably includes a power supply 21 with which the current supplied to the seats via the supply line 17 can be fed in. System 18 preferably further includes a control device 19 which is suitable for converting commands provided via a data connection for activating and / or deactivating the temperature control devices 3 / heaters 3 of the seats in such a way that these can be transmitted (as described) via the supply line 17 to the seats 1 or the temperature control devices 3 / heaters 4 of the seats 1 and their control units 16. The control device 19 can in particular have a gateway 25 via which System 18 can communicate with Server 20. A corresponding gateway 25 for this communication is preferably provided on Server 20. The gateways 25 enable communication between the components of System 18 and Server 20 via a network 22 – preferably via the Internet.A business logic 23 and a device management system 24 for operating the system 18 are preferably provided on server 20. Seat temperature control / heating functions can be booked via mobile devices 14. Specific seats 1 can be identified by mobile devices 14 using identifiers 15 on the seats 1. Booking requests can then be transmitted from the mobile device 14 to server 20 or to the business logic 23 provided on server 20. Bookings are then managed there and, if necessary, translated into control commands for the seats 1 or their temperature control devices 3 / heaters 3, which the gateways 25, networks 22, control devices 19, etc., transmit to the seats 1 or their control units 16. Figure 8 shows a flowchart of a procedure according to which the system shown in Figure 7 can be operated.According to step a), the seat for which a temperature control function is to be activated is first identified using an attached identifier. This is preferably done with a mobile device. Subsequently, according to step b), the temperature control is booked. This is preferably done via the described system. This regularly requires payment for activating the temperature control system. The booking, payment, and activation are preferably carried out via a server of the system or via business logic running on a server. According to step c), the system transmits an activation command to the seat or to a control unit of the seat. Subsequently, according to step d), the seat (1) is temperature-controlled according to the booking made in step b).
