Summary of the Invention

Problems to be Solved by the Invention

[0004] However, since the conventional technique only moves the entire seat in accordance with the movement of the character, there is a problem that it is difficult for the user to feel the presence of the character.

[0005] Therefore, an object of the present invention is to make it easier for a user to feel the presence of a character.

Means for Solving the Problems

[0006] To solve the above problems, a seat system according to the present invention includes a seat on which a user can sit, an electric device that moves a predetermined part that is a part of the seat, a control unit that controls the electric device, and a display unit. The control unit can display, on the display unit, a sheet image imitating a sheet and a character image. The control unit causes the display unit to display a video in which the character image performs an action on a part corresponding to a predetermined part in the sheet image, and executes an image-sheet linkage process of moving a predetermined part by an electric device in accordance with the action of the character image.

[0007] According to this configuration, when the character image performs an action on a part of the sheet image, a part of the sheet moves by the electric device, so that the user can more easily 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 thus can touch the character through the sheet.

[0008] Also, the character image may be an image imitating an animal.

[0009] According to this, the user can touch the animal through the sheet, so that a soothing effect can be obtained. Also, when the animal is smaller than the sheet, the user can feel the presence of the animal near the part of the sheet that has moved by moving a part of the sheet by the electric device.

[0010] Also, the sheet includes a seat cushion and a seat back as a predetermined part, the electric device is an electric reclining mechanism for tilting the seat back, and the control unit may tilt the seat back backward by the electric reclining mechanism in accordance with the character image tilting backward the part corresponding to the seat back in the sheet image.

[0011] Further, the seat includes a seat cushion and a seat back. The predetermined part is at least a part of the seating surface of the seat cushion. The electric device is a device that moves the predetermined part upward. The control unit may move the predetermined part upward by the electric device in accordance with the pushing up of the part of the character image corresponding to the predetermined part of the seat image.

[0012] Further, the predetermined part is a part of the seating surface of the seat. The electric device is a device that moves the predetermined part between a first position and a second position that protrudes more toward the user side than the first position. The control unit may reciprocate the predetermined part between the first position and the second position by the electric device in accordance with the repeated movement of the part of the character image corresponding to the predetermined part of the seat image.

[0013] Further, the seat includes a heater. The control unit may display the character image at a position corresponding to the heater in the seat image and operate the heater.

[0014] According to this, by heating a part of the seat corresponding to the position where the character image exists in the seat image with the heater, the user can feel the body temperature of the character through the seat.

[0015] Further, the control unit may execute the image-seat interlocking process when an operation command for operating the electric device is input.

[0016] Further, the control unit may execute the image-seat interlocking process when there is no input of an operation command for operating the electric device and another condition different from the operation command is satisfied.

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

[0018] According to this, since the control unit restricts the movement of the electric device based on the driving state of the vehicle, for example, when driving on a curve, etc., when the driving state is such that the user would feel uncomfortable if the electric device is moved, the movement of the electric device can be restricted to enhance comfort.

[0019] Also, the vehicle includes a road condition detection unit that detects the road condition, and the control unit may restrict the movement of the electric device based on the road condition.

[0020] According to this, since the control unit restricts the movement of the electric device based on the road condition, for example, when stopped on a slope, etc., when the road condition is such that the user would feel uncomfortable if the electric device is moved, the movement of the electric device can be restricted to enhance comfort.

Advantages of the Invention

[0021] According to the present invention, when a character image causes an action on a part of the seat image, a part of the seat moves by the electric device, so that the user can more easily feel the presence of the character.

[0022] Also, by making the character image an image imitating an animal, the user can touch the animal through the seat, so that a soothing effect can be obtained. Also, when the animal is smaller than the seat, by moving a part of the seat by the electric device, the user can feel that the animal exists near the moved part of the seat.

[0023] Also, when the control unit displays the character image at a position corresponding to the heater in the seat image and operates the heater, the user can feel the body temperature of the character through the seat.

[0024] Also, by restricting the movement of the electric device based on the driving state of the vehicle by the control unit, comfort can be enhanced.

[0025] In addition, by restricting the movement of the electric device based on the road conditions, the comfort can be improved.

Mode for Carrying Out the Invention

[0027] [First Embodiment] Hereinafter, a first embodiment of the sheet system will be described with reference to the accompanying drawings. As shown in Fig. 1, the sheet 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 seating surface F that can contact the user.

[0028] The seat cushion 11 has a base portion 11A disposed at the center of the left and right, and overhanging portions 11B disposed on both outer sides of the base portion 11A. The base portion 11A contacts and supports the user's buttocks and thighs from below. The overhanging portion 11B protrudes toward the user from the base portion 11A to support the sides of the user's thighs and buttocks.

[0029] Similarly, the seat back 12 also has a base portion 12A disposed at the center of the left and right, and overhanging portions 12B disposed on both outer sides of the base portion 12A. The base portion 12A contacts the user's back and supports the back from behind. The overhanging portion 12B protrudes 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 skin SK. The frame FL is made of metal or the like and supports the pad P. The pad P is made of a cushion material such as urethane foam. The skin SK is made of synthetic leather, fabric, or the like and covers the pad P. Also, the seat back 12 and the headrest 13 similarly include a frame, a pad, and a skin.

[0031] Returning to FIG. 1, the seat 10 further includes an electric reclining mechanism 21, a plurality of air cells 22, a plurality of vibration devices 23, an electric slide mechanism 30, a plurality of heaters 41 to 44, and a plurality of speakers 50. The electric reclining mechanism 21, the air cells 22, the vibration devices 23, the electric slide mechanism 30, the heaters 41 to 44, and the plurality of speakers 50 are electric devices that operate when energized. Among these electric devices, the electric reclining mechanism 21, the air cells 22, and the vibration devices 23 are electric devices that move only a part of the seat 10. In other words, the electric reclining mechanism 21, the air cells 22, and the vibration devices 23 partially move a part of the seat 10.

[0032] The electric reclining mechanism 21 is a mechanism for tilting the seat back 12. The electric reclining mechanism 21 includes a motor that operates when energized.

[0033] The air cell 22 includes an inflatable / contractible bag 22A, a pump (not shown), and a tube. The pump has a function of sending air into the bag 22A or sucking air out of the bag 22A and operates when energized. 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 the frame of the seat 10, for example. The bag 22A can move a part of the seating 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 more toward the user side than the first position.

[0035] Returning to FIG. 1, the seat cushion 11 has a plurality of bags 22A. A plurality of, 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 projecting portions 11B of the seat cushion 11.

[0036] The seat back 12 has a plurality of bags 22A. A plurality of, 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 projecting 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 device 23 is, for example, embedded in a pad.

[0038] The electric slide mechanism 30 is a mechanism that slides the seat 10 in the front-rear direction. Here, the seat 10 is supported movably in the front-rear direction on a slide rail (not shown). The electric slide mechanism 30 includes a motor that operates when energized.

[0039] The heaters 41 to 44 are planar heating elements that generate heat when energized. The heaters 41 to 44 are arranged between the skin 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 one by one on the left and right projecting 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 one by one on the left and right projecting portions 12B of the seat back 12.

[0041] The speaker 50 is a device that generates sound when energized. The speakers 50 are provided one on each side, left and right, at the upper part of the seat back 12. The speakers 50 are provided one on each side, left and right, of the headrest 13. The speaker 50 is, for example, embedded in the 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 operation unit for operating the electric reclining mechanism 21. The reclining switch 61 is, for example, tiltable in the front-rear direction. When the reclining switch 61 is tilted forward, it outputs a forward tilt command for tilting the seat back 12 forward to the control unit 100. When the reclining switch 61 is tilted rearward, it outputs a rear tilt command for tilting the seat back 12 rearward to the control unit 100.

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

[0045] The mode changeover 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 that prohibits the second control described later. The second mode is a mode that permits the second control. The mode changeover switch 63 is, for example, a push-button type switch. Each time the mode changeover switch 63 is pressed by the user, it alternates between the ON state and the OFF state.

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

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

[0048] The first control is a control for setting an electric device to a first operating state corresponding to an operation command when the operation command is acquired from the operation unit. In other words, the first control is a control for operating the electric device 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 electric reclining mechanism 21 is operated so that the seat back 12 tilts forward, and if the command is a rearward tilt command, the electric reclining mechanism 21 is operated so that the seat back 12 tilts rearward. Also, when the control unit 100 executes the first control based on a command from the slide switch 62, if the command is a forward movement command, the electric slide mechanism 30 is operated so that the seat 10 moves forward, and if the command is a backward movement command, the electric slide mechanism 30 is operated so that the seat 10 moves backward.

[0050] The second control is a control for setting an electric device to a second operating state not corresponding to an operation command when the operation command is acquired from the operation unit. In other words, the second control is a control for operating the electric device in an operating state contrary to the intention of the user.

[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 electric reclining mechanism 21 is actuated so that the seat back 12 tilts backward, and if the command is a backward tilt command, the electric reclining mechanism 21 is actuated so that the seat back 12 tilts forward. Further, when the control unit 100 executes the second control based on a command from the slide switch 62, if the command is a forward movement command, the electric slide mechanism 30 is actuated so that the seat 10 moves backward, and if the command is a backward movement command, the electric slide mechanism 30 is actuated so that the seat 10 moves forward. That is, the control unit 100 controls the electric device so as to perform an operation opposite to the operation command in the second control.

[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 slide mechanism 30 correspond to mechanisms that move the movable part between a first position and a second position. And, 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 the control unit 100 executes the first control, the movable part is moved from the first position toward the second position, and when the control unit 100 executes the second control, the movable part is moved 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 acquired from the operation unit. In other words, the third control is a control that does not operate the electric device contrary to the user's intention.

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

[0055] The control unit 100 can be switched between a first mode and a second mode by a mode changeover switch 63. The first mode is a mode in which the electric device operates according to the user's intended operation. 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 touch the 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 is also referred to as the "cat mode".

[0057] In the cat mode, the control unit 100 controls various electric devices according to the actions performed by the cat displayed on the screen M1 of the monitor M on the seat. In the cat mode, the electric device may operate according to the user's intended operation, operate contrary to the intention, or not operate contrary to the intention.

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

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

[0060] In the cat mode, the control unit 100 displays a sheet image G1 imitating the sheet 10 and a character image G2 imitating a cat on the screen M1 of the monitor M. In the cat mode, the control unit 100 causes the screen M1 to display a video in which the character image G2 performs an action on the sheet image G1, and executes an image-sheet interlocking process in which at least a part of the sheet 10 is moved by an electric device in accordance with the action of the character image G2. Here, the timing of starting the playback of the video and the timing of starting the operation of the electric device may be the same, or either one may be earlier.

[0061] In the cat mode, when an operation command for operating the electric device is input, the control unit 100 selects the first control, the second control, and the third control, and executes the image-sheet interlocking 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 the cat mode, even when there is no input of an operation command for operating the electric device and another condition is satisfied, the control unit 100 executes the image-sheet interlocking process. In the present embodiment, the other condition is "no input of an operation command for a predetermined period of time". In the image-sheet interlocking process executed when there is no input of an operation command, the control unit 100 randomly selects a video (image) to be displayed on the screen M1, and operates the corresponding electric device in accordance with the selected video. Note that the control unit 100 may randomly select the electric device to be operated and display a video corresponding to the movement of the selected electric device on the screen M1.

[0063] Hereinafter, specific examples of the image-sheet interlocking process will be described. As shown in FIGS. 6(a) and 6(b), when the control unit 100 reclines the seat back 12, it causes the screen M1 to display a video in which the character image G2 acts on the portion of the seat image G1 corresponding to the seat back 12, and reclines the seat back 12 by the electric reclining mechanism 21 in accordance with the action of the character image G2. In the present embodiment, the control unit 100 causes the screen M1 to display a video in which a cat hangs down on the portion near the seat back of the seat image G1 and the seat back portion of the seat image G1 gradually falls backward. Further, the control unit 100 causes the screen M1 to display an image of characters such as "Nya~, recline the seat backward", which indicates the movement of the cat.

[0064] Note that the control unit 100 may output the content indicated by the image of the characters as voice through the speaker 50. In this case, it is preferable to output the voice from the speaker 50 closest to the position of the mouth of the cat on the screen M1, for example, the speaker 50 of the headrest 13.

[0065] The control unit 100 causes the electric reclining mechanism 21 to tilt the actual seat back 12 backward in accordance with the character image G2 tilting the seat back portion of the seat image G1 backward. That is, the control unit 100 operates the electric reclining mechanism 21 in accordance with the movement of the seat back portion of the seat image G1 that gradually falls backward due to the hanging of the cat, and gradually tilts the actual seat back 12 backward.

[0066] When reclining the seat back 12 forward, for example, a video in which a cat pushes the seat back portion forward may be displayed on the screen M1, or a video in which a cat pulls the upper portion of the seat back portion forward using a rope or the like may be displayed on the screen M1. Also when reclining the seat back 12 forward, the control unit 100 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] As shown in FIGS. 7(a) and 7(b), when the control unit 100 slides the seat 10 backward, it causes the screen M1 to display a video in which the cat and the seat move backward as the cat pushes the seat from the front. In accordance with the movement of the cat and the seat, the control unit 100 moves the seat 10 backward by means of the electric slide mechanism 30. Further, the control unit 100 displays on the screen M1 an image of characters such as "Move the seat backward nya~" and an image showing the movement of the cat. In this case as well, similar to the above, the content of the character image may be output as sound from the speaker 50.

[0068] When the seat 10 is to be slid forward, for example, a video in which the cat pushes the seat forward may be displayed on the screen M1, or a video in which the cat pulls the seat from the front using a rope or the like may be displayed on the screen M1. Also when the seat 10 is slid forward, the control unit 100 gradually moves the actual seat 10 forward in accordance with the movement of the cat and the seat on the screen M1.

[0069] As shown in FIGS. 8(a) and 8(b), when the control unit 100 causes the screen M1 to display a video in which the cat crawls under the seat cushion, in accordance with the character image G2 pushing up the seat cushion portion of the seat image G1, the control unit 100 operates the air cell 22 disposed in the base portion 11A of the seat cushion 11, thereby moving a part of the seating surface F of the base portion 11A upward. The air cell 22 to be operated may be at least one of the two left and right air cells 22. Further, the control unit 100 displays on the screen M1 an image of characters such as "Crawl under the seat nya~" and an image showing the movement of the cat. In this case as well, similar to the above, the content of the character image may be output as sound from the speaker 50.

[0070] As shown in FIGS. 9(a) and 9(b), when the control unit 100 displays on the screen M1 a video of a cat relaxing at the overhanging portion of the seat cushion, the character image G2 repeatedly moves a part of the overhanging portion of the seat image G1 by expanding and contracting its body by breathing. In accordance with this, the air cell 22 disposed in the overhanging portion 11B of the seat cushion 11 is expanded and contracted. As a result, the air cell 22 reciprocates a part of the seat surface F of the overhanging portion 11B of the seat cushion 11 between the first position and the second position.

[0071] Further, when the control unit 100 displays on the screen M1 a video of a cat relaxing at the overhanging portion of the seat cushion, the control unit 100 activates the heater 42 disposed in the overhanging portion 11B. In other words, the control unit 100 displays the character image G2 at a position corresponding to the heater 42 and the air cell 22 in the seat image G1, and activates the heater 42 and the air cell 22. Note that the temperature of the heater 42 is preferably set to a temperature corresponding to the body temperature of the cat.

[0072] Further, the control unit 100 displays on the screen M1 an image of characters such as "Relaxing nya~" that indicates the state of the cat. Also in this case, similar to the above, the content of the character image may be output as audio from the speaker 50.

[0073] In the actual seat 10, there are overhanging portions 11B on the left and right. When the seat displayed on the screen M1 is an image viewed from the side, the air cell 22 and the heater 42 provided in at least one of the two overhanging portions 11B may be activated. Also, when the seat on the screen is a three-dimensional image viewed obliquely or an image viewed from the front, the air cell 22 and the heater 42 disposed in the overhanging portion 11B on the side where the cat is located may be activated.

[0074] As shown in FIGS. 10(a) and 10(b), when the control unit 100 displays a video of a cat scratching its claws on the seat back on the screen M1, the control unit 100 operates the vibration device 23 and the speaker 50 in the seat back 12 in accordance with the movement of the front paw of the scratching cat. Specifically, when the cat on the screen M1 is scratching the seat back with its left front paw, the control unit 100 vibrates the left vibration device 23 and outputs a sound of scratching the seat from the left speaker 50. When the cat on the screen M1 is scratching the seat back with its right front paw, the control unit 100 vibrates the right vibration device 23 and outputs a 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 operate at least one vibration device 23 on the left side and at least one vibration device 23 on the right side.

[0076] When the control unit 100 displays 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. In addition, the control unit 100 displays an image of characters such as "I'm going for a walk, nya~" on the screen M1, which shows the movement of the cat. In this case as well, similar to the above, the content of the character image may be output as audio from the speaker 50.

[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 switch 63 is ON (S1). If it is determined in step S1 that the mode switch 63 is not ON (No), the control unit 100 sets the mode to the first mode, that is, the normal mode (S2), and ends this process. When an operation command is input in the normal mode, the control unit 100 only executes the first control.

[0078] If it is determined in step S1 that the mode change switch 63 is ON (Yes), the control unit 100 sets the mode to the second mode, that is, 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 change switch 63 is ON (S13).

[0079] If it is determined in step S13 that the mode change 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 change 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, the second control, and the 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, if 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, if 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, if 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 it is determined as No in step S5, the control unit 100 determines whether the slide switch 62 has been operated (S8). If it is determined in step S8 that the slide switch 62 has been operated (Yes), the control unit 100 randomly selects one control from the first control, the second control, and the 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 control to be executed on the screen M1 (S7), and ends this process.

[0083] Specifically, for example, if the operation command from the slide switch 62 is a backward 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 sheet 10 backward by the electric slide mechanism 30. Also, for example, if 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 sheet 10 backward by the electric slide mechanism 30. Also, for example, if 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 it is determined as No in step S8, the control unit 100 determines whether a predetermined time has elapsed since the start of the second mode or when the operation unit (61, 62) was last operated (S10). If it is determined in step S10 that the predetermined time has not elapsed (No), the control unit 100 returns to the process 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 FIGS. 6 to 11 and displays it on the screen M1 (S11). After step S11, the control unit 100 controls the electric device according to the selected image (S12), and ends this process.

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

[0087] When the user presses the mode switch 63 to turn it on, the control unit 100 switches to the cat mode. In the cat mode, first, the control unit 100 displays the home screen shown in Fig. 5(a) on the screen M1. In the 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, by looking at the screen M1, the user can recognize that the cat is helping with their operation, thus developing an affection for the cat.

[0088] Also, in the 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 contrary to the user's intention. At this time, the user is surprised by the operation contrary to their own, but since the screen M1 shows the cat tilting the seat back backward, the user recognizes that it is the cat's doing and is healed by the cat's self-willedness of not listening.

[0089] Also, in the cat mode, when 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, although the user is surprised that the seat back 12 does not move even when the reclining switch 61 is operated, since a video of a cat going for a walk is displayed on the screen M1, the user is healed by the capricious behavior of the cat.

[0090] Also, in the cat mode, when the user does not operate the operation unit for a predetermined time, the control unit 100 randomly selects an image to be displayed from the images shown in Figs. 6 to 11 and controls the electric device according to the selected image. When the image of Fig. 6, Fig. 7 or Fig. 10 is selected, the user is surprised that the entire seat 10 or the seat back 12 moves on its own, or sudden vibration and scratching sounds occur, but by looking at the screen M1, the user can know that it is due to the mischief of the cat, and thus is healed by the behavior of the mischievous 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 cell 22 or the like, and thus develops an attachment to the cat.

[0092] After executing the first control, the second control or the third control, the control unit 100 returns the display of the screen M1 to the home screen (S1: Yes → S3 → S4). When the home screen is displayed on the screen M1, if the user turns off the mode change 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 change switch 63 is switched from ON to OFF, the control unit 100 erases the cat mode image displayed on the screen M1.

[0093] As described above, according to the present embodiment, the following effects can be obtained. When the character image G2 on the screen M1 performs an action on a part of the sheet image G1, a part of the actual sheet 10 moves by an 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, allowing the user to feel as if the cat is pressing the user through the sheet 10, enabling the user to touch the cat through the sheet 10.

[0094] By making the character image G2 an image imitating a cat, the user can touch the cat through the sheet 10, thus obtaining a soothing effect. Also, by moving a part of the sheet 10 with an electric device, the user can feel the presence of the cat near the moved part of the sheet 10.

[0095] By heating a part of the sheet 10 corresponding to the position where the character image G2 exists in 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, if the user operates the operation unit, the electric device will enter an operating state that the user does not intend, thus enhancing the entertainment value.

[0097] When the second control is executed, the seat back 12 or the sheet 10 moves in the direction opposite to that when the first control is executed, thus enhancing the entertainment value.

[0098] Since a mode change switch 63 for switching between prohibiting and permitting the second control is provided, the user can switch between prohibiting and permitting the second control according to their will.

[0099] In the cat mode, by selecting one of the first control, the second control, and the third control, the user does not know at what timing the second control will be executed, thus enhancing the entertainment value.

[0100] When the second control is selected in the cat mode, the user can know through the screen M1 that the electric device is operating in an operating state unintended by the user due to the movement of the cat on the screen M1, so that the user can be healed.

[0101] When the first control is selected in the cat mode, the cat moves the seat as intended by the user, so that the user can be healed.

[0102] [Second Embodiment] Next, a second embodiment of the seat system according to the present invention will be described. Since this embodiment slightly changes the processing of the control unit 100 according to the first embodiment, the same reference numerals will be given to the components and processes substantially the same as those in the first embodiment, and the description thereof will be omitted.

[0103] As shown in FIG. 12, in the second embodiment, the seat system 1 is provided in the vehicle 70. The vehicle 70 includes, in addition to the seat system 1, a camera 71 as an example of a running state detection unit and an acceleration sensor 72 as an example of a road condition detection unit.

[0104] Note that the running state detection unit may be, for example, a detection sensor for the steering angle, an accelerator sensor, a brake sensor, or the like. The road condition detection unit may be a device that acquires map information of a navigation system or the like.

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

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

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

[0108] Specifically, the control unit 100 executes the process shown in FIG. 13. The process in FIG. 13 is obtained by adding the processes of new steps S31 to S36 to the process in FIG. 4.

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

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

[0111] When the control unit 100 determines that there is an operation of the slide switch 62 in step S8 (Yes), based on the information from the camera 71 or the acceleration sensor 72, it determines whether the vehicle 70 is traveling on a curve or the road is a slope (S33). If it is determined in step S33 that the vehicle is traveling on a curve or the road is a slope (Yes), the control unit 100 prohibits the operation of the electric slide mechanism 30 by selecting the third control (S32).

[0112] If it is determined in step S33 that the vehicle is not traveling on 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, and the third control.

[0113] If the control unit 100 determines in step S10 that a predetermined time has elapsed (Yes), it determines whether the vehicle 70 is traveling on a curve or the road is on a slope based on the information from the camera 71 or the acceleration sensor 72 (S34). In step S34, if it is determined that the vehicle is traveling on a curve or is 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, according to the second embodiment, the following effects can be obtained. When the vehicle 70 is traveling on a curve, the operation of the electric device is prohibited. Therefore, for example, it is possible to suppress movements that make the user feel uncomfortable, such as the seat back 12 falling backward unexpectedly during a curve, and improve comfort.

[0115] When the vehicle 70 is located on a slope, the operation of the electric device is prohibited. Therefore, for example, it is possible to suppress movements that make the user feel uncomfortable, such as the seat back 12 falling backward unexpectedly during uphill driving, and improve comfort.

[0116] Note that the present invention is not limited to the above-described embodiment and 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 previous seat to the rear seat as shown in FIG. 14(a) and display it on the screen M1.

[0118] When the image in FIG. 14(a) is selected, the control unit 100 tilts the seat back 12 of the front seat 10 forward by the electric reclining mechanism 21 in accordance with the movement of the cat flying from the front seat on the screen M1. The control unit 100 slides the rear seat 10 backward by the electric slide mechanism 30 in accordance with the timing when the cat on the screen M1 lands on the rear seat, tilts the seat back 12 of the rear seat 10 backward by the electric reclining mechanism 21, and operates the vibration device 23.

[0119] According to this embodiment, since the plurality of seats 10 are moved in accordance with the movement of the cat on the screen M1, the entertainment property can be further enhanced. When the seat system includes a plurality of seats, a monitor may be provided one by one for each seat. In this case, the monitor may be provided on the door beside the seat.

[0120] In the above embodiment, in the second control, the first electric device (for example, the electric reclining mechanism 21) corresponding to the first operation unit (for example, the reclining switch 61) is operated in the second operating state, but the present invention is not limited to this. For example, in the second control, the control unit may operate a second electric device that cannot be originally operated by the first operation unit, and move the character image in accordance with the operating 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 by the electric slide mechanism 30. In the second control, when the second electric device is operated, the first electric device may be in any state. For example, the first electric device may be in a state of operating in the second operating state, a state of not operating, or a state of operating 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] As a condition for the image sheet interlocking process to be executed when there is no input of an operation command to operate the electric device, it is not limited to time, and for example, conditions such as the vehicle having stopped may also be acceptable.

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

[0131] When the vehicle is capable of executing autonomous driving, the control unit may prohibit the second control during manual driving and permit the second control during autonomous driving. Also, the control unit may permit the second control during high-speed auto cruise and prohibit the second control at times other than during auto cruise. Also, the control unit may permit the second control while the vehicle is stopped and prohibit the second control while the vehicle is in motion.

[0132] The system including the control unit that executes the image sheet interlocking process may be a system that does not include a seat. For example, the system may include an interior member of the 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 to be displayed on the screen is not limited to a seat image, and a user image imitating the user may also be acceptable. In this case, when an action occurs in a character image in a part of the user image, the part of the seat corresponding to the part of the user image may move by the electric device. Specifically, for example, a video in which a cat alternately steps on the user's waist with its left and right front paws may be displayed on the screen, and an air cell in a part of the seat back (the part corresponding to the user's waist) may be inflated and deflated.

[0134] The electric device is not limited to the above embodiment, and may be, for example, a blower, a light, a device that generates an odor, a device that rotates a seat around a vertical axis, or the like. When a blower is provided on the seat and it is possible to direct the air from the blower to the user from the seating surface of the seat, the blower may be operated when displaying the image shown in Fig. 9(a) on the screen M1. In this case, the breathing of the cat can be simulated by the air from the blower.

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

[0136] The operation unit may be, for example, a microphone that outputs an operation command by voice input, a device that captures the user's gesture (body movement) and outputs an operation command corresponding to the gesture.

[0137] The seat may be a vehicle seat used in an automobile, or other vehicle seats, such as seats used in ships or airplanes. Also, the seat is not limited to vehicle seats, and may be, for example, a chair, furniture, an outdoor chair, a waiting chair in a hospital, a park bench, a bed, a mattress, or the like.

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

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

[0140] The seat may include a middle folding mechanism, a switch for operating the middle folding mechanism, a headrest moving mechanism, a switch for operating the headrest moving mechanism, and the like. Here, the middle folding mechanism is, for example, a mechanism that tilts the upper part of the seat back back and forth with respect to the lower part. The headrest moving mechanism is a mechanism that moves the headrest in the vertical direction or the front-rear direction. Also in this case, the control unit may execute first control corresponding to an operation command from each switch and second control not corresponding to the 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 of a car navigation system, or the like. Also, the display unit may be a panel that displays a speedometer or the like as an image, a device that displays an image on a window such as a windshield, or a projection device incorporated in a headlight that displays an image on the road surface.

[0142] The character displayed on the screen may be changeable by the user's selection. In this case, the action may be changed for each character. For each character, the type of electric actuator to be operated, the frequency of operating the electric actuator, and the magnitude of the output of the electric actuator may be set.

[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]
