Description

[Technical Field]

[0001] The present invention relates to a seat system including a seat and a vehicle including the seat system. [Background technology]

[0002] Conventionally, there is known a technique for moving a user's seat in accordance with the movement of a character placed in an augmented reality space when the character moves the user's seat so as to move closer to the user (see Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 2020-042334 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the conventional technology, the entire sheet simply moves in accordance with the character's movements, which makes it difficult for the user to sense the character's presence.

[0005] Therefore, an object of the present invention is to make it easier for the user to sense the presence of the character, and to enhance the entertainment value of the seat. [Means for solving the problem]

[0006] In order to solve the above problem, the seat system of the present invention comprises a seat equipped with a first electric device and a second electric device that are activated by electricity being passed through, a first operating unit for operating the first electric device, and a control unit that operates the first electric device based on a first operating command from the first operating unit. The control unit randomly selects and executes a first control that places the first electric device in a first operating state corresponding to the first operating command when a first operation command is received from the first operating unit, and a second control that operates the second electric device when a first operation command is received from the first operating unit. This configuration can enhance the entertainment value of the seat.

[0007] The seat system also includes a seat on which a user can sit, an electric device that moves a predetermined portion of the seat, a control unit that controls the electric device, and a display unit. The control unit can display a sheet image simulating a sheet and a character image on the display unit. The control unit displays a video in which the character image takes action on a part of the sheet image corresponding to a predetermined part, and executes an image sheet linkage process in which an electric device moves the predetermined part in accordance with the action of the character image. With this configuration, when the character image takes action on a part of the sheet image, that part of the sheet moves due to the electric device, making it easier for the user to feel the presence of the character. Specifically, for example, when the character presses a part of the sheet image, the electric device presses a part of the sheet, so that the user can feel as if the character is pressing the user through the sheet, and can thus come into contact with the character through the sheet.

[0008] The character image may also be an image that resembles an animal.

[0009] This allows the user to interact with the animal through the seat, which has a soothing effect. Also, if the animal is smaller than the seat, the electric device can move part of the seat, allowing the user to feel the presence of the animal near the moved part of the seat.

[0010] The seat may also include a seat cushion and a seat back as a specified part, the electric device may be an electric reclining mechanism that tilts the seat back, and the control unit may tilt the seat back backward using the electric reclining mechanism in accordance with the character image tilting backward the part of the seat image corresponding to the seat back.

[0011] The seat may also include a seat cushion and a seat back, the specified portion being at least a part of the seat surface of the seat cushion, the electric device being a device that moves the specified portion upward, and the control unit may cause the electric device to move the specified portion upward in accordance with the character image pushing up the portion of the seat image that corresponds to the specified portion.

[0012] In addition, the specified portion may be a part of the seat surface of the seat, the electric device may be a device that moves the specified portion between a first position and a second position that protrudes further toward the user than the first position, and the control unit may use the electric device to move the specified portion back and forth between the first position and the second position in accordance with the character image repeatedly moving the portion of the seat image that corresponds to the specified portion.

[0013] The seat may also include a heater, and the control unit may display a character image at a position on the seat image corresponding to the heater and activate the heater.

[0014] According to this, by heating a part of the sheet corresponding to the position where the character image is present on the sheet image with a heater, the user can feel the body temperature of the character through the sheet.

[0015] The control unit may also execute the image sheet linkage process when an operation command to operate the electric device is input.

[0016] The control unit may also execute the image sheet linkage process when no operation command to operate the electric device is input and a condition other than the operation command is satisfied.

[0017] A vehicle according to the present invention includes the seat system and a driving condition detection unit that detects a driving condition of the vehicle. The control unit acquires the driving state from the driving state detection unit, and restricts the movement of the electric device based on the acquired driving state.

[0018] With this, the control unit limits the movement of the electric device based on the vehicle's driving conditions, so that when the driving conditions are such that moving the electric device would cause discomfort to the user, such as when driving around a curve, the movement of the electric device can be limited, thereby increasing comfort.

[0019] The vehicle may also include a road condition detection unit that detects road conditions, and the control unit may limit the movement of the electric device based on the road conditions.

[0020] With this, the control unit restricts the movement of the electric device based on road conditions, so that when the road conditions are such that moving the electric device would cause discomfort to the user, for example when the vehicle is stopped on a slope, the movement of the electric device can be restricted, thereby increasing comfort. [Effects of the Invention]

[0021] According to the present invention, the entertainment value of the seat can be enhanced. In addition, when the character image takes action on a part of the seat image, the part of the seat moves by the electric device, making it easier for the user to feel the presence of the character.

[0022] Furthermore, by using an image of an animal as the character image, the user can interact with the animal through the seat, which has a soothing effect. Furthermore, if the animal is smaller than the seat, the user can feel the presence of the animal near the moved part of the seat by moving a part of the seat with an electric device.

[0023] Furthermore, the control unit displays the character image at a position on the seat image corresponding to the heater, and activates the heater, allowing the user to feel the body temperature of the character through the seat.

[0024] Furthermore, the control unit can limit the movement of the electric device based on the driving state of the vehicle, thereby improving comfort.

[0025] Furthermore, the control unit can limit the movement of the electric device based on road conditions, thereby improving comfort. [Brief explanation of the drawings]

[0027] [First embodiment] A first embodiment of the seat system will be described below with reference to the accompanying drawings. 1, the seat system 1 includes a seat 10 on which a user can sit, a monitor M as an example of a display unit, and a control unit 100. The seat 10 includes a seat cushion 11, a seat back 12, and a headrest 13. The seat cushion 11, the seat back 12, and the headrest 13 each constitute a seat body having a seat surface F that can come into contact with the user.

[0028] The seat cushion 11 has a base portion 11A located in the left-right center and protruding portions 11B located on both the left and right outer sides of the base portion 11A. The base portion 11A contacts and supports the user's buttocks and thighs from below. The protruding portions 11B protrude from the base portion 11A toward the user to support the sides of the user's thighs and buttocks.

[0029] Similarly, the seat back 12 has a base portion 12A located in the center of the seat back and overhanging portions 12B located on both the left and right sides of the base portion 12A. The base portion 12A contacts the back of the user to support the back from behind. The overhanging portions 12B overhang toward the user to support the sides of the user's upper body.

[0030] As shown in FIG. 2, the seat cushion 11 includes a frame FL, a pad P, and a cover SK. The frame FL is made of metal or the like and supports the pad P. The pad P is made of a cushioning material such as urethane foam. The cover SK is made of synthetic leather, fabric, or the like and covers the pad P. Similarly, the seat back 12 and the headrest 13 also include a frame, a pad, and a cover.

[0031] Returning to FIG. 1 , seat 10 further includes electric reclining mechanism 21, multiple air cells 22, multiple vibration devices 23, electric slide mechanism 30, multiple heaters 41-44, and multiple speakers 50. Electric reclining mechanism 21, air cells 22, vibration device 23, electric slide mechanism 30, heaters 41-44, and multiple speakers 50 are electric devices that are activated when electricity is applied. Of these electric devices, electric reclining mechanism 21, air cells 22, and vibration device 23 are electric devices that move only a portion of seat 10. In other words, electric reclining mechanism 21, air cells 22, and vibration device 23 move a portion of seat 10.

[0032] The electric reclining mechanism 21 is a mechanism that tilts the seat back 12. The electric reclining mechanism 21 includes a motor that is activated by energization.

[0033] The air cell 22 includes an inflatable / deflateable bag 22A, a pump, and a tube (not shown). The pump has the function of sending air into the bag 22A and sucking air out of the bag 22A, and is activated by passing electricity. The tube connects the bag 22A and the pump.

[0034] As shown in Fig. 2, the bag 22A is embedded in the pad. The pump is fixed to, for example, the frame of the seat 10. The bag 22A is capable of moving a part of the seat surface F of the seat 10 between a first position shown in Fig. 2(a) and a second position shown in Fig. 2(b). Here, the second position is a position that protrudes further toward the user than the first position.

[0035] Returning to Fig. 1, the seat cushion 11 has a plurality of bags 22A. A plurality of bags 22A, for example, two bags 22A, are arranged on the base portion 11A of the seat cushion 11. One bag 22A is arranged on each of the left and right protruding portions 11B of the seat cushion 11.

[0036] The seat back 12 has a plurality of bags 22A. A plurality of bags 22A, for example, four bags 22A, are arranged on the base portion 12A of the seat back 12. One bag 22A is arranged on each of the left and right protruding portions 12B of the seat back 12.

[0037] The vibration device 23 is a device that vibrates when energized. A plurality of, for example, four, vibration devices 23 are provided on the base portion 12A of the seat back 12. The vibration devices 23 are embedded in, for example, a pad.

[0038] The electric slide mechanism 30 is a mechanism for sliding the seat 10 in the front-rear direction. The seat 10 is supported on a slide rail (not shown) so that it can move in the front-rear direction. The electric slide mechanism 30 is equipped with a motor that is activated by energization.

[0039] The heaters 41 to 44 are planar heating elements that generate heat when energized. The heaters 41 to 44 are arranged between the cover and the pad (see FIG. 2). The heater 41 is provided on the base portion 11A of the seat cushion 11. The heaters 42 are provided on each of the left and right protruding portions 11B of the seat cushion 11.

[0040] The heater 43 is provided on the base portion 12A of the seat back 12. The heaters 44 are provided on the left and right protruding portions 12B of the seat back 12, one each.

[0041] The speakers 50 are devices that generate sound when energized. One speaker 50 is provided on each of the left and right sides of the upper part of the seat back 12. One speaker 50 is provided on each of the left and right sides of the headrest 13. The speakers 50 are embedded in, for example, a pad.

[0042] The seat 10 further includes a reclining switch 61, a slide switch 62, and a mode changeover switch 63.

[0043] The reclining switch 61 is an operating unit for operating the electric reclining mechanism 21. The reclining switch 61 can be tilted, for example, in the front-to-rear direction. When tilted forward, the reclining switch 61 outputs a forward tilt command to the control unit 100 to tilt the seat back 12 forward. When tilted rearward, the reclining switch 61 outputs a rearward tilt command to the control unit 100 to tilt the seat back 12 rearward.

[0044] The slide switch 62 is an operating unit for operating the electric slide mechanism 30. The slide switch 62 is slidable, for example, in the front-to-rear direction. When the slide switch 62 is slid forward, it outputs a forward movement command to the control unit 100 to move the seat 10 forward. When the slide switch 62 is slid rearward, it outputs a backward movement command to the control unit 100 to move the seat 10 rearward.

[0045] The mode selector switch 63 is a switch for switching the mode of the control unit 100 between a first mode and a second mode. Here, the first mode is a mode in which a second control, which will be described later, is prohibited. The second mode is a mode in which the second control is permitted. The mode selector switch 63 is, for example, a push button switch. The mode selector switch 63 alternates between an ON state and an OFF state each time the user presses it.

[0046] The control unit 100 is configured to include, for example, a CPU, RAM, ROM, input / output circuits, etc. The control unit 100 may be provided in the seat 10, or may be provided in a member other than the seat 10.

[0047] 3, the control unit 100 is connected to the monitor M, various switches (61-63), and various electric devices (21-23, 30, 41-44, 50). The control unit 100 can individually operate each of the heaters 41-44, and can also individually operate each of the air cells 22, the vibration devices 23, and the speakers 50. The control unit 100 has a function of selecting and executing a first control, a second control, or a third control.

[0048] The first control is a control that, when an operation command is received from the operation unit, causes the electric device to enter a first operating state corresponding to the operation command. In other words, the first control is a control that causes the electric device to operate in an operating state as intended by the user.

[0049] Specifically, when the control unit 100 executes the first control based on a command from the reclining switch 61, if the command is a forward tilt command, the control unit 100 operates the electric reclining mechanism 21 to tilt the seat back 12 forward, and if the command is a rearward tilt command, the control unit 100 operates the electric reclining mechanism 21 to tilt the seat back 12 rearward. Furthermore, when the control unit 100 executes the first control based on a command from the slide switch 62, if the command is a forward command, the control unit 100 operates the electric slide mechanism 30 to move the seat 10 forward, and if the command is a rearward command, the control unit 100 operates the electric slide mechanism 30 to move the seat 10 rearward.

[0050] The second control is a control that, when an operation command is received from the operation unit, causes the electric device to enter a second operating state that does not correspond to the operation command. In other words, the second control is a control that causes the electric device to operate in an operating state that is contrary to the user's intention.

[0051] Specifically, when the control unit 100 executes the second control based on a command from the reclining switch 61, if the command is a forward tilt command, the control unit 100 operates the electric reclining mechanism 21 to tilt the seat back 12 backward, and if the command is a rearward tilt command, the control unit 100 operates the electric reclining mechanism 21 to tilt the seat back 12 forward. Furthermore, when the control unit 100 executes the second control based on a command from the slide switch 62, if the command is a forward move command, the control unit 100 operates the electric slide mechanism 30 to move the seat 10 backward, and if the command is a backward move command, the control unit 100 operates the electric slide mechanism 30 to move the seat 10 forward. In other words, in the second control, the control unit 100 controls the electric device to perform an operation opposite to that of the operation command.

[0052] Here, the seat back 12 and the seat 10 correspond to a movable part that is at least a part of the seat 10. The electric reclining mechanism 21 and the electric sliding mechanism 30 correspond to a mechanism that moves the movable part between a first position and a second position. For example, a forward tilt command and a forward movement command correspond to commands that move the movable part from the first position toward the second position. When executing the first control, the control unit 100 moves the movable part from the first position toward the second position, and when executing the second control, the control unit 100 moves the movable part from the second position toward the first position.

[0053] The third control is a control that does not operate the electric device when an operation command is received from the operation unit. In other words, the third control is a control that does not operate the electric device against the user's intention.

[0054] Specifically, when the control unit 100 executes the third control, it does not operate the electric reclining mechanism 21 even when it receives a command from the reclining switch 61. Furthermore, when the control unit 100 executes the third control, it does not operate the electric slide mechanism 30 even when it receives a command from the slide switch 62.

[0055] The control unit 100 can be switched between a first mode and a second mode by the mode selector switch 63. The first mode is a mode in which the electric device operates in response to an action intended by the user. In the following description, the first mode is also referred to as the "normal mode."

[0056] The second mode is a mode in which the user can interact with a cat displayed on the screen M1 of the monitor M shown in Fig. 5 through the seat 10. In the following description, the second mode will also be referred to as a "cat mode."

[0057] In the cat mode, the control unit 100 controls various electric devices in accordance with actions taken by the cat displayed on the screen M1 of the monitor M on the seat. In the cat mode, the electric devices may operate in accordance with the user's intended action, operate in accordance with an unintended action, or not operate in accordance with the user's intended action.

[0058] The control unit 100 is in the normal mode when the mode changeover switch 63 is in the OFF state, and in the cat mode when the mode changeover switch 63 is in the ON state.

[0059] When the control unit 100 is in normal mode and an operation command is input, the control unit 100 executes only the first control. When the control unit 100 is in cat mode and an operation command is input, the control unit 100 randomly selects and executes the first control, the second control, and the third control. Note that the probabilities for selecting each control may be the same or different. For example, the probability for selecting the first control may be higher than the probabilities for selecting the second control and the third control.

[0060] In the cat mode, the control unit 100 displays a sheet image G1 that resembles a sheet 10 and a character image G2 that resembles a cat on the screen M1 of the monitor M. In the cat mode, the control unit 100 displays a video on the screen M1 in which the character image G2 performs an action on the sheet image G1, and executes an image sheet linkage process in which the electric device moves at least a part of the sheet 10 in accordance with the action of the character image G2. Here, the timing at which the playback of the video and the timing at which the electric device starts to operate may be simultaneous, or one may start first.

[0061] In the cat mode, when an operation command to operate an electric device is input, the control unit 100 selects the first, second, or third control and executes the image sheet linkage process. Specifically, the control unit 100 moves the character image G2 in accordance with the state of the electric device corresponding to the selected control.

[0062] In cat mode, the control unit 100 also executes the image sheet linkage process when no operation command to operate an electric device is input and a condition other than the operation command is satisfied. In this embodiment, the other condition is "no operation command is input for a predetermined time." In the image sheet linkage process executed when no operation command is input, the control unit 100 randomly selects a video (image) to display on the screen M1 and activates the corresponding electric device in accordance with the selected video. Note that the control unit 100 may also randomly select an electric device to operate and display a video corresponding to the movement of the selected electric device on the screen M1.

[0063] A specific example of the image sheet linked processing will be described below. 6(a) and 6(b), when the seat back 12 is tilted backward, the control unit 100 displays on the screen M1 a video in which a character image G2 performs an action on a portion of the seat image G1 corresponding to the seat back 12, and tilts the seat back 12 backward by the electric reclining mechanism 21 in accordance with the action of the character image G2. In this embodiment, the control unit 100 displays on the screen M1 a video in which a cat hangs near the seat back of the seat image G1, and the seat back portion of the seat image G1 gradually tilts backward. The control unit 100 also displays on the screen M1 an image of text such as "Tilt the seat back meow" that indicates the cat's action.

[0064] The control unit 100 may output the content displayed by the text image as sound using the speaker 50. In this case, it is preferable to output the sound from the speaker 50 closest to the position of the cat's mouth on the screen M1, for example, the speaker 50 of the headrest 13.

[0065] In accordance with the character image G2 tilting the seat back portion of the seat image G1 backward, the control unit 100 tilts the actual seat back 12 backward using the electric reclining mechanism 21. In other words, in accordance with the movement of the seat back portion of the seat image G1 that is tilting backward due to the cat hanging down, the control unit 100 operates the electric reclining mechanism 21 to gradually tilt the actual seat back 12 backward.

[0066] When tilting the seat back 12 forward, for example, a video of a cat pushing the seat back portion forward may be displayed on the screen M1, or a video of a cat pulling the upper part of the seat back portion from the front using a rope or the like may be displayed on the screen M1. When tilting the seat back 12 forward, the control unit 100 also gradually tilts the actual seat back 12 forward in accordance with the movement of the cat and the movement of the seat back portion on the screen M1.

[0067] 7(a) and 7(b), when sliding seat 10 rearward, control unit 100 displays on screen M1 a video of a cat pushing the seat from the front, causing the cat and the seat to move rearward, and controls electric sliding mechanism 30 to move seat 10 rearward in accordance with the movement of the cat and the seat. Control unit 100 also displays on screen M1 an image of text such as "Move the seat back, meow" that indicates the cat's movements. In this case, the content of the text image may also be output as sound from speaker 50, as described above.

[0068] When sliding the seat 10 forward, for example, a video of a cat pushing the seat forward may be displayed on the screen M1, or a video of a cat pulling the seat from the front using a rope or the like may be displayed on the screen M1. When sliding the seat 10 forward, the control unit 100 also gradually moves the actual seat 10 forward in accordance with the movement of the cat and the movement of the seat on the screen M1.

[0069] As shown in FIGS. 8(a) and 8(b), when displaying a video of a cat crawling under the seat cushion on screen M1, the control unit 100 activates the air cells 22 arranged on the base 11A of the seat cushion 11 in synchronization with the character image G2 pushing up the seat cushion portion of the seat image G1, thereby moving a part of the seat surface F of the base 11A upward. Note that it is sufficient that at least one of the two air cells 22 on the left and right sides be activated. The control unit 100 also displays an image of text, such as "Cat crawling under the seat," on screen M1, which indicates the cat's action. Note that in this case, the content of the text image may also be output as sound from the speaker 50, as described above.

[0070] 9(a) and 9(b), when displaying on screen M1 a video of a cat relaxing on a protruding portion of a seat cushion, the control unit 100 causes the character image G2 to expand and contract its body through breathing, thereby repeatedly moving a part of the protruding portion of the seat image G1, and in response, causes the air cells 22 arranged in the protruding portion 11B of the seat cushion 11 to expand and contract. As a result, the air cells 22 cause a part of the seat surface F of the protruding portion 11B of the seat cushion 11 to reciprocate between a first position and a second position.

[0071] Furthermore, when displaying on screen M1 a video of a cat relaxing on the protruding portion of the seat cushion, control unit 100 activates heater 42 arranged on protruding portion 11B. In other words, control unit 100 displays character image G2 in a position on seat image G1 corresponding to heater 42 and air cell 22, and activates heater 42 and air cell 22. The temperature of heater 42 is preferably set to a temperature equivalent to the body temperature of the cat.

[0072] Furthermore, the control unit 100 displays on the screen M1 an image of text such as "Relaxing Meow" that indicates the state of the cat. In this case, too, the content of the text image may be output as sound from the speaker 50, as in the above case.

[0073] In actuality, the sheet 10 has protruding portions 11B on the left and right, so if the sheet displayed on the screen M1 is an image seen from the side, it is sufficient to activate the air cell 22 and heater 42 provided on at least one of the two protruding portions 11B. Also, if the sheet on the screen is a three-dimensional image seen from an angle or an image seen from the front, it is sufficient to activate the air cell 22 and heater 42 provided on the protruding portion 11B on the left or right where the cat is located.

[0074] 10(a) and 10(b), when displaying a video of a cat scratching the seatback on screen M1, the control unit 100 activates the vibration device 23 and the speaker 50 in the seatback 12 in accordance with the movement of the cat's front paws. Specifically, when the cat on screen M1 is scratching the seatback with its left front paw, the control unit 100 vibrates the left vibration device 23 and outputs the sound of scratching the seat from the left speaker 50. When the cat on screen M1 is scratching the seatback with its right front paw, the control unit 100 vibrates the right vibration device 23 and outputs the sound of scratching the seat from the right speaker 50.

[0075] Since there are two vibration devices 23 on the left side and two on the right side, the control unit 100 only needs to activate at least one vibration device 23 on the left side and at least one vibration device 23 on the right side.

[0076] When displaying a video of a cat going for a walk on the screen M1, the control unit 100 moves the character image G2 away from the seat image G1 and does not operate the electric device for moving a part of the seat 10. The control unit 100 also displays an image of text such as "I'm going for a walk, meow" on the screen M1, which shows the movement of the cat. In this case, the content of the text image may also be output as sound from the speaker 50, as described above.

[0077] Next, the operation of the control unit 100 will be described in detail. The control unit 100 repeatedly executes the process shown in Fig. 4. In the process shown in Fig. 4, the control unit 100 first determines whether the mode changeover switch 63 is ON (S1). If it is determined in step S1 that the mode changeover switch 63 is not ON (No), the control unit 100 sets the mode to the first mode, i.e., the normal mode (S2), and ends this process. Note that if an operation command is input in the normal mode, the control unit 100 executes only the first control.

[0078] If it is determined in step S1 that the mode changeover switch 63 is ON (Yes), the control unit 100 sets the mode to the second mode, i.e., the cat mode (S3), and displays the home screen shown in Fig. 5 on the screen M1 (S4). After step S4, the control unit 100 determines whether the mode changeover switch 63 is ON (S13).

[0079] If it is determined in step S13 that the mode changeover switch 63 is ON (Yes), the control unit 100 determines whether the reclining switch 61 has been operated (S5). If it is determined in step S13 that the mode changeover switch 63 is not ON (No), the control unit 100 ends this process.

[0080] If it is determined in step S5 that the reclining switch 61 has been operated (Yes), the control unit 100 randomly selects one control from the first control, second control, and third control corresponding to the operation command from the reclining switch 61 (S6). After step S6, the control unit 100 executes the selected control and displays an image corresponding to the executed control on the screen M1 (S7), and ends this process.

[0081] Specifically, for example, when the operation command from the reclining switch 61 is a rearward tilt command and the first control is selected, the control unit 100 displays the video shown in FIG. 6(a) on the screen M1 and tilts the seat back 12 backward by the electric reclining mechanism 21. Also, for example, when the operation command from the reclining switch 61 is a forward tilt command and the second control is selected, the control unit 100 displays the video shown in FIG. 6(a) on the screen M1 and tilts the seat back 12 backward by the electric reclining mechanism 21. Also, for example, when the third control is selected, the control unit 100 displays the video shown in FIG. 11(a) on the screen M1 and does not operate the electric reclining mechanism 21.

[0082] If the determination in step S5 is No, the control unit 100 determines whether or not the slide switch 62 has been operated (S8). If the determination in step S8 is that the slide switch 62 has been operated (Yes), the control unit 100 randomly selects one control from the first control, second control, and third control corresponding to the operation command from the slide switch 62 (S9). After step S9, the control unit 100 executes the selected control and displays an image corresponding to the executed control on the screen M1 (S7), and ends this process.

[0083] Specifically, for example, when the operation command from the slide switch 62 is a reverse command and the first control is selected, the control unit 100 displays the video shown in FIG. 7(a) on the screen M1 and moves the seat 10 backward by the electric slide mechanism 30. Also, for example, when the operation command from the slide switch 62 is a forward command and the second control is selected, the control unit 100 displays the video shown in FIG. 7(a) on the screen M1 and moves the seat 10 backward by the electric slide mechanism 30. Also, for example, when the third control is selected, the control unit 100 displays the video shown in FIG. 11(a) on the screen M1 and does not operate the electric slide mechanism 30.

[0084] If the determination in step S8 is No, the control unit 100 determines whether a predetermined time has elapsed since the start of the second mode or the last time the operation units (61, 62) were operated (S10). If the determination in step S10 is that the predetermined time has not elapsed (No), the control unit 100 returns to the processing of step S5.

[0085] If it is determined in step S10 that the predetermined time has elapsed (Yes), the control unit 100 randomly selects an image to be displayed from the images shown in Figures 6 to 11 and displays it on the screen M1 (S11). After step S11, the control unit 100 controls the electric device in accordance with the selected image (S12), and ends this process.

[0086] Next, a specific example of the operation of the control unit 100 will be described. 1, in the normal mode, when a user seated in the seat 10 tilts the reclining switch 61 rearward, the control unit 100 executes the first control, causing the seat back 12 to tilt rearward as intended by the user. Also, when the user slides the slide switch 62 rearward, the control unit 100 executes the first control, causing the seat 10 to move rearward as intended by the user.

[0087] When the user presses the mode selector switch 63 to turn it ON, the control unit 100 switches to cat mode. In cat mode, the control unit 100 first displays the home screen shown in FIG. 5(a) on the screen M1. In cat mode, when the user tilts the reclining switch 61 backward and a backward tilt command is output from the reclining switch 61, if the control unit 100 selects the first control, the control unit 100 displays the image shown in FIG. 6(a) on the screen M1 and tilts the seat back 12 backward as intended by the user. At this time, the user can recognize that the cat is helping them with their operation by looking at the screen M1, and thus the user will grow attached to the cat.

[0088] Furthermore, in cat mode, when the user tilts the reclining switch 61 forward and a forward tilt command is output from the reclining switch 61, if the control unit 100 selects the second control, the control unit 100 displays the image shown in Fig. 6(a) on the screen M1 and tilts the seat back 12 backward against the user's intention. At this time, the user is surprised that the opposite action to his or her own operation is being performed, but since the action of the cat tilting the seat back backward is displayed on the screen M1, the user realizes that it is the cat's doing and is comforted by the selfishness of the cat that refuses to listen to orders.

[0089] Furthermore, in cat mode, if the user operates the reclining switch 61 and the control unit 100 selects the third control, the control unit 100 displays the image shown in Fig. 11(a) on the screen M1 and does not move the seat back 12. At this time, the user is surprised that the seat back 12 does not move even when the reclining switch 61 is operated, but the video of the cat going for a walk is displayed on the screen M1, and the user is soothed by the cat's whimsical behavior.

[0090] Furthermore, in cat mode, if the user does not operate the operation unit for a predetermined time, the control unit 100 randomly selects an image to display from the images shown in Figures 6 to 11 and controls the electric device according to the selected image. When the image of Figure 6, 7, or 10 is selected, the user may be surprised by the entire seat 10 or seat back 12 moving on its own, or by sudden vibrations and scratching sounds, but by looking at screen M1, the user can see that the cause is the cat's mischief, and can be comforted by the mischievous behavior of the cat.

[0091] When the image of FIG. 8 or FIG. 9 is selected, the user can feel the presence of the cat through the seat 10 due to the movement of the air cells 22, etc., and thus develops an attachment to the cat.

[0092] After executing the first control, second control, or third control, the control unit 100 returns the display of screen M1 to the home screen (S1: Yes → S3 → S4). When the home screen is displayed on screen M1, if the user turns off the mode selector switch 63 to end the cat mode, the control unit 100 changes the mode to the normal mode (S13: No → S1: No → S2). Note that when the mode selector switch 63 is switched from on to off, the control unit 100 erases the cat mode image that was displayed on screen M1.

[0093] As described above, according to this embodiment, the following effects can be obtained. When the character image G2 on the screen M1 takes action on a part of the sheet image G1, a part of the actual sheet 10 moves due to the electric device, making it easier for the user to feel the presence of the cat. Specifically, for example, when the cat presses a part of the sheet, the electric device presses a part of the actual sheet 10, so that the user can feel as if the cat is pushing the user through the sheet 10, and can thus interact with the cat through the sheet 10.

[0094] By making the character image G2 an image that resembles a cat, the user can have a soothing effect by interacting with the cat through the seat 10. In addition, by moving a part of the seat 10 with an electric device, the user can feel the presence of a cat near the part of the seat 10 that has moved.

[0095] By heating a part of the sheet 10 corresponding to the position of the character image G2 on the sheet image G1 with the heater 42, the user can feel the body temperature of the cat through the sheet 10.

[0096] When the control unit 100 executes the second control or the third control, when the user operates the operation unit, the electric device enters an operating state that is not intended by the user, which can enhance the entertainment value.

[0097] When the second control is executed, the seat back 12 or the seat 10 moves in the opposite direction to when the first control is executed, which can enhance the entertainment value.

[0098] Since the mode changeover switch 63 is provided to switch between prohibition and permission of the second control, the second control can be switched between prohibition and permission at the user's discretion.

[0099] In cat mode, one control is selected from the first control, the second control, and the third control, so the user does not know when the second control will be executed, which makes the game more entertaining.

[0100] When the second control is selected in cat mode, the cat's movements on screen M1 let the user know through screen M1 that the electric device is operating in an unintended state, which can soothe the user.

[0101] When the first control is selected in the cat mode, the cat moves the seat as intended by the user, providing comfort to the user.

[0102] [Second embodiment] Next, a second embodiment of the seat system according to the present invention will be described. Note that since this embodiment is a slight modification of the processing of the control unit 100 according to the first embodiment, the same components and processing as those in the first embodiment will be assigned the same reference numerals and descriptions thereof will be omitted.

[0103] 12, in the second embodiment, the seat system 1 is provided in a vehicle 70. In addition to the seat system 1, the vehicle 70 also includes a camera 71 as an example of a driving condition detection unit and an acceleration sensor 72 as an example of a road condition detection unit.

[0104] The driving condition detection unit may be, for example, a sensor for detecting a steering angle, an accelerator sensor, a brake sensor, etc. The road condition detection unit may be a device for acquiring map information from a navigation system, etc.

[0105] The camera 71 has a function of detecting the traveling state of the vehicle 70. Specifically, in this embodiment, the camera 71 detects that the vehicle 70 is traveling around a curve.

[0106] The acceleration sensor 72 has a function of detecting road conditions. Specifically, in this embodiment, the acceleration sensor 72 detects whether the road on which the vehicle 70 is traveling or stopped is a slope.

[0107] The control unit 100 acquires information from the camera 71 and the acceleration sensor 72. The control unit 100 restricts the movement of the electric device based on the driving state acquired from the camera 71 or the road conditions acquired from the acceleration sensor 72. Specifically, the control unit 100 prohibits the operation of the electric device when it determines that the vehicle 70 is traveling around a curve or the road is a slope.

[0108] More specifically, the control unit 100 executes the process shown in Fig. 13. The process in Fig. 13 is the process in Fig. 4 with the addition of new steps S31 to S36.

[0109] If control unit 100 determines in step S5 that reclining switch 61 has been operated (Yes), it determines whether vehicle 70 is traveling around a curve or on a slope based on information from camera 71 or acceleration sensor 72 (S31). If it determines in step S31 that vehicle 70 is traveling around a curve or on a slope (Yes), control unit 100 selects third control (S32) to prohibit operation of electric reclining mechanism 21. After step S32, control unit 100 proceeds to the processing of step S7, executes third control, and displays an image corresponding to the third control on screen M1.

[0110] If it is determined in step S31 that the vehicle is not traveling around a curve and is not on a slope (No), the control unit 100 proceeds to the process of step S6 and randomly selects the first control, the second control, or the third control.

[0111] If the control unit 100 determines in step S8 that the slide switch 62 has been operated (Yes), it determines whether the vehicle 70 is traveling around a curve or on a slope (S33) based on information from the camera 71 or the acceleration sensor 72. If it determines in step S33 that the vehicle 70 is traveling around a curve or on a slope (Yes), the control unit 100 selects the third control (S32) to prohibit the operation of the electric slide mechanism 30.

[0112] If it is determined in step S33 that the vehicle is not traveling around a curve and is not on a slope (No), the control unit 100 proceeds to the process of step S9 and randomly selects the first control, the second control, or the third control.

[0113] If the control unit 100 determines in step S10 that the predetermined time has elapsed (Yes), it determines whether the vehicle 70 is traveling around a curve or on a slope based on information from the camera 71 or the acceleration sensor 72 (S34). If it determines in step S34 that the vehicle 70 is traveling around a curve or on a slope (Yes), the control unit 100 selects an image corresponding to the third control (S35). After step S35, the control unit 100 executes the third control (S36) and ends this process.

[0114] As described above, the second embodiment can provide the following effects. Since the operation of the electric device is prohibited when the vehicle 70 is traveling around a curve, it is possible to suppress movements that make the user feel uncomfortable, such as the seat back 12 accidentally tilting backward while traveling around a curve, thereby improving comfort.

[0115] When the vehicle 70 is located on a slope, the operation of the electric device is prohibited, so that movements that make the user feel uncomfortable, such as the seat back 12 accidentally tilting backward while traveling uphill, can be suppressed, thereby improving comfort.

[0116] The present invention is not limited to the above-described embodiment, but can be used in various forms as exemplified below.

[0117] As shown in Fig. 14(b), the seat system 2 may include a plurality of seats 10. In this case, the control unit 100 may select in step S11 a video of a cat jumping from the front seat to the back seat, as shown in Fig. 14(a), and display it on the screen M1.

[0118] 14(a) is selected, the control unit 100 causes the seat back 12 of the front seat 10 to fold forward by the electric reclining mechanism 21 in synchronization with the movement of the cat on the screen M1 jumping from the front seat. The control unit 100 causes the rear seat 10 to slide backward by the electric sliding mechanism 30, and also causes the seat back 12 of the rear seat 10 to fold backward by the electric reclining mechanism 21, and activates the vibration device 23 in synchronization with the timing when the cat on the screen M1 lands on the rear seat.

[0119] According to this embodiment, the plurality of seats 10 move in accordance with the movement of the cat on the screen M1, further enhancing the entertainment value. Note that if the seat system has a plurality of seats, one monitor may be provided for each seat. In this case, the monitor may be provided in the door next to the seat.

[0120] In the above embodiment, the second control activates the first electric device (e.g., electric reclining mechanism 21) corresponding to the first operation unit (e.g., reclining switch 61) in the second operation state, but the present invention is not limited to this. For example, the control unit may activate a second electric device that cannot be operated by the first operation unit in the second control, and move the character image in accordance with the operation state of the second electric device.

[0121] Specifically, for example, when the reclining switch 61 is operated, the control unit 100 may display the image shown in FIG. 7(a) on the screen M1 and slide the seat 10 using the electric sliding mechanism 30. Note that when the second electric device is operated in the second control, the first electric device may be in any state. For example, the first electric device may be in an operating state in the second operating state, an inoperable state, or an operating state in the first operating state.

[0122] According to this embodiment, when the control unit 100 executes the second control, when the user operates the first operating unit, the second electric device, which cannot normally be operated by the first operating unit, is activated, thereby enhancing the entertainment value.

[0123] In addition, for example, the second electric device and the third electric device may be activated in the second control. Specifically, for example, when the reclining switch 61 is operated, the image shown in Fig. 9(a) may be displayed on the screen M1, and the air cell 22 and the heater 42 may be activated.

[0124] According to this aspect, when the second control is executed, two electric devices different from the first electric device are operated, which can enhance the entertainment value.

[0125] The character image is not limited to a cat, and may be an image of an animal other than a human. The character image may also be an image of a person. Even if the character image is an image of a person, the control unit may use an electric device to move a part of the actual seat in accordance with the action of the person on the screen, such as tapping the seat, allowing the user to interact with the person on the screen through the seat.

[0126] The character image may be smaller than the sheet image or larger than the sheet image. If the character image is smaller than the sheet image, the character can be placed on the sheet, crawl under the sheet, or perform a variety of other actions.

[0127] The positions and number of the electric devices are not limited to those in the above embodiment and can be changed as desired.

[0128] The electric device that moves at least a portion of the seat surface of the seat cushion upward is not limited to an air cell, but may be, for example, an electric tilt-up mechanism or an electric height mechanism. In the case of an electric tilt-up mechanism or an electric height mechanism, the entire seat surface of the seat cushion moves upward.

[0129] The condition for the image sheet linked process to be executed when no operation command to operate the electric device is input is not limited to time, but may be, for example, that the vehicle has stopped.

[0130] The electrically powered device that moves a predetermined portion of the seat between the first position and the second position is not limited to an air cell, and may be, for example, an electrically powered lumbar support that supports the user's driving posture.

[0131] If the vehicle is capable of autonomous driving, the control unit may prohibit the second control during manual driving and permit the second control during autonomous driving.The control unit may also permit the second control during auto-cruise at high speeds and prohibit the second control at times other than auto-cruise.The control unit may also permit the second control when the vehicle is stopped and prohibit the second control when the vehicle is moving.

[0132] The system including the control unit that executes the image sheet linkage process may be a system that does not include a sheet. For example, the system may include an interior member of a vehicle, an electric device that moves a part of the interior member, a control unit that controls the electric device, and a screen.

[0133] The image displayed on the screen is not limited to a seat image, but may also be a user image that resembles the user. In this case, when a character image takes action on a part of the user image, the part of the seat corresponding to that part of the user image may be moved by an electric device. Specifically, for example, a video of a cat stepping alternately on the user's waist with its left and right front paws may be displayed on the screen, causing air cells in a part of the seat back (the part corresponding to the user's waist) to expand and contract.

[0134] The electric device is not limited to the above embodiment, and may be, for example, a blower, a light, a device that emits a scent, or a device that rotates the seat around a vertical axis. If the seat is provided with a blower and the air from the blower can be directed toward the user from the seat surface, the blower may be operated when the image shown in FIG. 9(a) is displayed on the screen M1. In this case, the air from the blower can simulate the sound of a cat breathing.

[0135] The function of executing the first control or the second control based on an operation command from an operation unit is not limited to seats, but can be applied to anything equipped with an electric device. For example, when the function is applied to a vehicle, when a user operates the switch of an air conditioner provided in the vehicle to increase the temperature, if the first control is executed, the set temperature will increase as usual, and if the second control is executed, the set temperature will decrease.

[0136] The operation unit may be a microphone that outputs operation commands based on voice input, or a device that captures a user's gesture (body movement) and outputs operation commands corresponding to the gesture.

[0137] The seat may be a vehicle seat used in an automobile, or may be a seat for other vehicles, such as a seat used in a ship or an aircraft, etc. The seat is not limited to a vehicle seat, and may be, for example, a floor chair, furniture or outdoor chair, hospital waiting room chair, park bench, bed, mattress, etc.

[0138] 15, the seat 10 may further include an ottoman 14 that supports the user's calves, an ottoman actuator 24 that rotates the ottoman, an ottoman switch 64 for activating the ottoman actuator 24, and an air cell switch 65 for activating the air cell 22 used as a lumbar support. In this case, the control unit 100 may activate at least one of the ottoman actuator 24 and the air cell 22 in accordance with the movement of the character displayed on the display unit.

[0139] In this case, the control unit 100 may execute a first control corresponding to an operation command from the ottoman switch 64 and a second control not corresponding to an operation command from the ottoman switch 64. Similarly, the control unit 100 may execute a first control corresponding to an operation command from the air cell switch 65 and a second control not corresponding to an operation command from the air cell switch 65.

[0140] The seat may be equipped with a seat back tilting mechanism, a switch for activating the seat back tilting mechanism, a headrest moving mechanism, a switch for activating the headrest moving mechanism, etc. Here, the seat back tilting mechanism is, for example, a mechanism for tilting the upper part of the seat back forward and backward relative to the lower part. The headrest moving mechanism is a mechanism for moving the headrest in the up-down direction and the back-and-forth direction. In this case, too, the control unit may execute a first control corresponding to an operation command from each switch and a second control not corresponding to an operation command from each switch.

[0141] The display unit may be a smartphone, a tablet terminal, a head-mounted display used for virtual reality, a monitor for a car navigation system, etc. The display unit may also be a panel that displays an image of a speedometer or the like, a device that displays an image on a window such as a windshield, or a projection device that is incorporated into a headlight and displays an image on the road surface.

[0142] The characters displayed on the screen may be changeable by user selection. In this case, the actions may be changed for each character. The type of electric actuator to be operated, the frequency at which the electric actuator is operated, and the magnitude of the output of the electric actuator may be set for each character.

[0143] For example, if the character is a bird, the electric devices (speakers, air cells, etc.) on the headrest and shoulders may be operated more frequently than for other characters. Also, if the character is a bird, the amount of movement of the part of the seat that moves in accordance with the character's movements may be smaller than when the character is an animal larger than a bird, such as a cat. Also, if the character is an animal larger than a cat, such as a dog, the speed of the part of the seat that moves in accordance with the character's movements may be increased. If the character is a reptile, such as a snake, the heater temperature may be lower than when the character is a mammal.

[0144] During autocruise, an image of a character operating the steering wheel may be displayed on the screen.

[0145] A sensor such as a camera may be used to detect the positional relationship with surrounding vehicles, and the movement of the electric device may be restricted based on the positional relationship.

[0146] The control unit may control the operation of the driver's seat differently from that of the other seats while the vehicle is running. For example, the driver's seat may be able to switch between the first mode and the second mode only when the vehicle is stopped, while the other seats may be able to switch between the first mode and the second mode at all times.

[0147] When a collision is detected or a collision is predicted, the control unit may stop the image display and operation in the second mode and activate a safety device.

[0148] The amount and speed of movement of the portion of the seat that moves in accordance with the character's movements may be changed depending on the user's physique. For example, the larger the user's physique (the heavier the user), the smaller the amount and speed of movement of the portion of the seat. Note that the physique detection unit that detects the physique may be, for example, a pressure sensor that detects pressure from the seat surface, an electromagnetic wave sensor, or a photographing device such as a camera.

[0149] The electric device to be operated may also be selected according to the user's physique. For example, when activating the air cells of the seat cushion in response to the movement of a cat crawling under the seat, only one air cell may be activated if the user's weight is below a predetermined value, and two air cells may be activated if the user's weight is above the predetermined value.

[0150] If the user's biological information is detected and fatigue is detected, the seat may move to help the user recover from fatigue, and an image corresponding to this movement may be displayed. The sensor for detecting the biological information may be a sensor that detects at least one of brain waves, facial expressions, eye movements, breathing, heart rate, pulse rate, etc. An example of a seat movement for helping the user recover from fatigue is massaging the user by activating the seat's air cells. An example of an image displayed in response to this movement is a video of a cat rubbing a part of the user's body.

[0151] The control unit may suggest various modes to the user, such as a play mode, a fatigue recovery mode, a relaxation mode, and a sleep mode. If there are multiple seats, the mode may be switchable for each seat. In the relaxation mode or the sleep mode, the control unit may operate air cells in the seat back in synchronization with the user's breathing to induce the user to sleep. In the relaxation mode or the sleep mode, the control unit may also display on the display unit a video of a cat alternately moving its left and right front paws to push against the seat back from behind.

[0152] The character's movements and messages may be changed based on the user's brain waves, facial expressions, gaze, and breathing. The control unit may recommend a character to the user that matches the user's hobbies and preferences based on user information such as gender and age. The control unit may also acquire user information from the user's smartphone, etc.

[0153] The control unit may distinguish the user based on user information, etc., and change the voice output of the character depending on the intimacy level with the user. Note that the intimacy level may be higher, for example, the longer the user has been in cat mode. The control unit may then make the character speak in a gentler manner as the intimacy level increases.

[0154] An illumination unit attached to the seat may operate in accordance with the display by the display unit or the operation of the seat.

[0155] The sheet system can be manufactured, for example, by the following method. A seat system comprising a seat on which a user can sit, an electric device that moves a specific part of the seat, a control unit that controls the electric device, and a display unit, wherein the control unit is capable of displaying a seat image that resembles the seat and a character image on the display unit, and the display unit displays a video in which the character image takes action on a part of the seat image that corresponds to the specific part, and a method for manufacturing a seat system that performs an image-sheet linkage process in which the electric device moves the specific part in accordance with the action of the character image, the method comprising the steps of attaching the electric device to a member that constitutes the seat, and attaching the control unit to the member that constitutes the seat.

[0156] The elements described in the above-described embodiment and modified examples may be implemented in any combination. [Explanation of symbols]
