Description

[Technical field]

[0001] The present invention relates to a seat equipped with an electric device and a seat system equipped with the seat. [Background technology]

[0002] Conventionally, there is known a seat system that includes an electric slide mechanism that slides the seat in the forward / rearward direction, a forward switch that commands the forward movement of the seat, a rear switch that commands the rearward movement of the seat, and a control unit that moves the seat in the direction desired by the user based on a command from the forward switch or the rear switch (see Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2022-185254 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the conventional technology, the seat can only be moved in the direction desired by the user, which is problematic in that it lacks entertainment value.

[0005] Therefore, an object of the present invention is to provide a seat and seat system that is equipped with an electric device and an operating unit that operates the electric device, and that provides enhanced entertainment value. [Means for solving the problem]

[0006] In order to solve the above problems, the seat of the present invention comprises a first electric device and a second electric device that are operated by passing electricity through them, 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 selectively 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 acquired from the first operating unit, and a second control that places the first electric device in a second operating state not corresponding to the first operating command and / or operates the second electric device when the first operation command is acquired from the first operating unit.

[0007] According to this configuration, when the control unit executes the second control, when the user operates the first operating unit, at least one of the first electric device and the second electric device goes into an operating state that is not intended by the user, thereby enhancing the entertainment value.

[0008] In addition, the first electric device may be a mechanism that moves a movable part that is at least a part of the seat between a first position and a second position, the first operation command is a command to move the movable part from the first position toward the second position, and the control unit may move the movable part from the first position toward the second position when executing the first control, and move the movable part from the second position toward the first position when executing the second control.

[0009] According to this configuration, when the second control is executed, the movable part moves in a direction opposite to that when the first control is executed, which can provide a high level of entertainment value.

[0010] The seat may further include a third electric device, and the control unit may operate the second electric device and the third electric device when receiving the first operation command from the first operation unit and executing the second control.

[0011] According to this configuration, when the second control is executed, two electric devices different from the first electric device are operated, which can enhance entertainment value.

[0012] The seat may also include a switch for switching between a first mode in which the second control is prohibited and a second mode in which the second control is permitted.

[0013] According to this configuration, the second control can be switched between being prohibited and permitted at the user's will.

[0014] In addition, in the second mode, the control unit may randomly select the first control or the second control.

[0015] According to this configuration, since the user does not know at what timing the second control will be executed, it is possible to enhance the entertainment value.

[0016] In addition, when the control unit obtains a first operation command from the first operation unit, it is capable of executing a third control that does not operate the first electric device, and in the second mode, it may randomly select the first control, the second control, and the third control.

[0017] According to this configuration, one control is selected from three controls in the second mode, which can enhance entertainment value.

[0018] A seat system according to the present invention includes the seat and a display unit. The control unit displays a sheet image resembling a seat and a character image on the display unit, and when executing the second control, moves the character image in accordance with the second operating state of the first electric device and / or the operating state of the second electric device.

[0019] According to this configuration, the user can know through the display unit that the character is causing the electric device to operate in an unintended operating state, which can comfort the user.

[0020] Furthermore, when executing the first control, the control unit may move the character image in accordance with the first operating state of the first electric device.

[0021] According to this configuration, the character moves as the user intends, providing a sense of relief to the user.

[0022] The seat according to the present invention also includes an electric device that is operated when electricity is applied, an operation unit for operating the electric device, and a control unit that operates the electric device based on an operation command from the operation unit. When the control unit receives an operation command from the operation unit, the control unit selects and executes a first control that puts the electric device into a first operating state corresponding to the operation command, and when the control unit receives an operation command from the operation unit, the control unit selects and executes a second control that puts the electric device into a second operating state that does not correspond to the operation command.

[0023] According to this configuration, when the control unit executes the second control, if the user operates the operation unit, the electric device goes into an operating state that is not intended by the user, thereby enhancing entertainment value. Effect of the Invention

[0024] According to the present invention, it is possible to enhance the entertainment value of a seat and a seat system that includes an electric device and an operating unit that operates the electric device.

[0025] Furthermore, by configuring the movable part to move in a direction opposite to that in which the first control is executed when the second control is executed, it is possible to enhance entertainment value.

[0026] Furthermore, by configuring two electric devices different from the first electric device to operate when the second control is executed, it is possible to enhance entertainment value.

[0027] Furthermore, by configuring the seat to include a switch for switching between the first mode and the second mode, the second control can be switched between being prohibited and permitted at the user's will.

[0028] In addition, by configuring the control unit to randomly select between the first control and the second control when in the second mode, the user does not know when the second control will be executed, making the experience more entertaining.

[0029] Moreover, by configuring the second mode so that one control is selected from three controls, it is possible to enhance entertainment value.

[0030] In addition, when the second control is executed, the character image is configured to move in accordance with the operating state of at least one of the first electric device and the second electric device, so that the user can know through the display unit that the character has caused the electric device to operate in an operating state that the user did not intend, thereby providing a sense of relief to the user.

[0031] Furthermore, by configuring the character image to move in accordance with the first operating state of the first electric device when the first control is executed, the character moves as intended by the user, providing a sense of relief to the user. [Brief description of the drawings]

[0033] [First embodiment] Hereinafter, a first embodiment of a seat system will be described with reference to the accompanying drawings. As shown in Fig. 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.

[0034] The seat cushion 11 has a base portion 11A disposed in the left-right center and overhanging portions 11B disposed on both 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 overhanging portions 11B overhang from the base portion 11A toward the user to support the sides of the user's thighs and buttocks.

[0035] Similarly, the seat back 12 has a base portion 12A disposed in the center of the seat back and overhanging portions 12B disposed on both the left and right outer 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.

[0036] 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.

[0037] 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 41-44, and a plurality of speakers 50. The electric reclining mechanism 21, the air cells 22, the vibration device 23, the electric slide mechanism 30, the heaters 41-44, and the plurality of speakers 50 are electric devices that are operated by energization. Of these electric devices, the electric reclining mechanism 21, the air cells 22, and the vibration device 23 are electric devices that move only a portion of the seat 10. In other words, the electric reclining mechanism 21, the air cells 22, and the vibration device 23 partially move a portion of the seat 10.

[0038] The electric reclining mechanism 21 is a mechanism that tilts the seat back 12. The electric reclining mechanism 21 includes a motor that is operated when electricity is applied.

[0039] The air cell 22 includes an inflatable / contractable bag 22A, and a pump and tube (not shown). The pump has the function of feeding air into the bag 22A and sucking air out of the bag 22A, and is operated by passing electricity through it. The tube connects the bag 22A and the pump.

[0040] 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 toward the user side from the first position.

[0041] Returning to Fig. 1, the seat cushion 11 has a plurality of bags 22A. A plurality of bags 22A, for example, two bags, are arranged on the base portion 11A of the seat cushion 11. One bag 22A is arranged on each of the left and right overhanging portions 11B of the seat cushion 11.

[0042] The seat back 12 has a plurality of bags 22A. A plurality of bags 22A, for example, four bags, are arranged on the base portion 12A of the seat back 12. One bag 22A is arranged on each of the left and right overhang portions 12B of the seat back 12.

[0043] The vibration device 23 is a device that vibrates when electricity is applied. 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 embedded in, for example, a pad.

[0044] 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 as to be movable in the front-rear direction. The electric slide mechanism 30 includes a motor that is operated by energization.

[0045] The heaters 41 to 44 are planar heating elements that generate heat when electricity is applied. The heaters 41 to 44 are disposed 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.

[0046] 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.

[0047] The speaker 50 is a device that generates sound when electricity is applied. 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 speaker 50 is embedded in, for example, a pad.

[0048] The seat 10 further includes a reclining switch 61, a slide switch 62, and a mode changeover switch 63.

[0049] The reclining switch 61 is an operation 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 for tilting the seat back 12 forward. When tilted rearward, the reclining switch 61 outputs a rearward tilt command to the control unit 100 for tilting the seat back 12 rearward.

[0050] The slide switch 62 is an operation unit for operating the electric slide mechanism 30. The slide switch 62 is slidable, for example, in the front-rear direction. When the slide switch 62 is slid forward, it outputs a forward movement command to the control unit 100 for moving the seat 10 forward. When the slide switch 62 is slid rearward, it outputs a backward movement command to the control unit 100 for moving the seat 10 rearward.

[0051] The mode changeover switch 63 is a switch for changing the mode of the control unit 100 between a first mode and a second mode. Here, the first mode is a mode forbidding a second control described later. Also, the second mode is a mode for permitting the second control. The mode changeover switch 63 is, for example, a push button type switch. The mode changeover switch 63 alternates between an ON state and an OFF state every time the user presses it.

[0052] 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 in the seat 10, or may be provided in a member other than the seat 10.

[0053] 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.

[0054] The first control is a control for putting the electric device into a first operating state corresponding to the 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.

[0055] 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 backward. In addition, when the control unit 100 executes the first control based on a command from the slide switch 62, if the command is a forward move 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 move backward command, the control unit 100 operates the electric slide mechanism 30 to move the seat 10 backward.

[0056] The second control is a control for putting the electric device into a second operating state that does not correspond to the 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 against the user's intention.

[0057] 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 so that the seat back 12 tilts backward, and if the command is a backward tilt command, the control unit 100 operates the electric reclining mechanism 21 so that the seat back 12 tilts 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 so that the seat 10 moves backward, and if the command is a backward move command, the control unit 100 operates the electric slide mechanism 30 so that the seat 10 moves forward. That is, in the second control, the control unit 100 controls the electric device so that the operation is the opposite to that of the operation command.

[0058] 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 first position toward the second position.

[0059] The third control is control not to operate the electric device when an operation command is received from the operation unit, in other words, the third control is control not to operate the electric device against the user's intention.

[0060] Specifically, when the control unit 100 executes the third control, the control unit 100 does not operate the electric reclining mechanism 21 even if a command is received from the reclining switch 61. Moreover, when the control unit 100 executes the third control, the control unit 100 does not operate the electric slide mechanism 30 even if a command is received from the slide switch 62.

[0061] The control unit 100 can be switched between a first mode and a second mode by the mode changeover switch 63. The first mode is a mode in which the electric device operates according to the user's intended action. In the following description, the first mode is also referred to as a "normal mode."

[0062] The second mode is a mode in which the user can interact with a cat displayed on a 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."

[0063] In the cat mode, the control unit 100 controls various electric devices according to 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 an unintended action.

[0064] The control unit 100 is in the normal mode when the mode change switch 63 is in the OFF state, and in the cat mode when the mode change switch 63 is in the ON state.

[0065] When the control unit 100 is in the normal mode and an operation command is input, the control unit 100 executes only the first control. When the control unit 100 is in the 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. The probability that each control is selected may be the same or different. For example, the probability that the first control is selected may be higher than the probability that the second control and the third control are selected.

[0066] 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 takes 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 starts and the timing at which the electric device starts to operate may be simultaneous, or one of them may start first.

[0067] In the cat mode, when an operation command to operate an electric device is input, the control unit 100 selects the first control, the second control, or the third control and executes the image sheet linking process. In detail, the control unit 100 moves the character image G2 according to the state of the electric device corresponding to the selected control.

[0068] In cat mode, the control unit 100 also executes the image sheet linkage process when there is no input of an operation command to operate the electric device 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 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 according to the selected video. Note that the control unit 100 may randomly select an electric device to be operated and display a video corresponding to the movement of the selected electric device on the screen M1.

[0069] A specific example of the image sheet linking process will be described below. 6(a) and (b), when the seat back 12 is tilted backward, the control unit 100 displays on the screen M1 a moving image of a character image G2 performing an action on a part 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 moving image in which a cat hangs on a part of the seat image G1 near the seat back, and the seat back part 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.

[0070] The control unit 100 may output the contents shown in the text image as sound by 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.

[0071] The control unit 100 tilts the actual seat back 12 backward by the electric reclining mechanism 21 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 is tilted backward by the cat hanging down, and gradually tilts the actual seat back 12 backward.

[0072] When the seat back 12 is tilted 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 the seat back 12 is tilted 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.

[0073] 7(a) and (b), when sliding the seat 10 backward, the control unit 100 displays on the screen M1 a moving image of the cat pushing the seat from the front, causing the cat and the seat to move backward, and moves the seat 10 backward by the electric sliding mechanism 30 in accordance with the movement of the cat and the seat. The control unit 100 also displays on the screen M1 an image of text such as "Move the seat backwards, meow!", which indicates the cat's movement. In this case, too, the content of the text image may be output as sound from the speaker 50, as in the above case.

[0074] When the seat 10 is slid 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. Even 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 movement of the seat on the screen M1.

[0075] As shown in Figs. 8(a) and (b), when the control unit 100 displays a moving image of a cat crawling under the seat cushion on the screen M1, the air cells 22 arranged on the base part 11A of the seat cushion 11 are actuated in accordance with the character image G2 pushing up the seat cushion part of the seat image G1, thereby moving a part of the seat surface F of the base part 11A upward. Note that it is sufficient that at least one of the two air cells 22 on the left and right sides is actuated. The control unit 100 also displays an image of text such as "Crawling under the seat" on the screen M1, which indicates the cat's action. Note that in this case, the content of the text image may be output as sound from the speaker 50, as in the above case.

[0076] 9(a) and (b), when displaying a video of a cat relaxing on a protruding portion of a seat cushion on a screen M1, the control unit 100 causes the air cells 22 arranged on the protruding portion 11B of the seat cushion 11 to expand and contract in accordance with the character image G2 repeatedly moving a part of the protruding portion of the seat image G1 by expanding and contracting its body through breathing. 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.

[0077] 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 at 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.

[0078] Furthermore, the control unit 100 displays an image of text such as "Relaxing Meow" on the screen M1, which indicates the state of the cat. Note that in this case, the content of the text image may be output as sound from the speaker 50, as in the above case.

[0079] In addition, since the actual sheet 10 has protruding portions 11B on the left and right, when the sheet displayed on the screen M1 is an image seen from the side, it is sufficient to operate the air cell 22 and heater 42 provided on at least one of the two protruding portions 11B. When the sheet on the screen is a stereoscopic image seen from an oblique angle or an image seen from the front, it is sufficient to operate the air cell 22 and heater 42 provided on the protruding portion 11B on the left or right where the cat is located.

[0080] 10(a) and 10(b), when displaying a video of a cat scratching the seat back on screen M1, the control unit 100 activates the vibration device 23 and the speaker 50 in the seat back 12 in accordance with the movement of the cat's front paws. In more detail, when the cat on screen M1 is scratching the seat back 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 seat back 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.

[0081] 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.

[0082] 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 an 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 indicates the movement of the cat. In this case, the content of the text image may be output as sound from the speaker 50, as in the above case.

[0083] 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 judges whether the mode change switch 63 is ON or not (S1). If it is judged in step S1 that the mode change 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. Note that, if an operation command is input in the normal mode, the control unit 100 executes only the first control.

[0084] When 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, 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 change switch 63 is ON (S13).

[0085] If it is determined in step S13 that the mode change switch 63 is ON (Yes), the control unit 100 determines whether or not 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.

[0086] 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 control to be executed on the screen M1 (S7), and ends this process.

[0087] Specifically, for example, when the operation command from the reclining switch 61 is a backward 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.

[0088] If the result of 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 result of 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, 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.

[0089] Specifically, for example, when 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 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.

[0090] If the result of step S8 is No, the control unit 100 determines whether or not 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 control unit 100 determines in step S10 that the predetermined time has not elapsed (No), the control unit 100 returns to the process of step S5.

[0091] 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.

[0092] 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 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.

[0093] When the user presses the mode change switch 63 to ON, the control unit 100 switches to the cat mode. In the cat mode, the control unit 100 first 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, the user can recognize that the cat is helping the user with the operation by looking at the screen M1, and thus the user feels an attachment to the cat.

[0094] In addition, 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 against the user's intention. At this time, the user is surprised that the opposite action to his / 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 who refuses to listen to orders.

[0095] Also, in the cat mode, when the user operates the reclining switch 61, if 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 since a video of the cat going for a walk is displayed on the screen M1, the user is soothed by the cat's whimsical behavior.

[0096] In addition, in the 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 is surprised when the entire seat 10 or the seat back 12 moves on its own, or when sudden vibrations and scratching sounds occur, but by looking at the screen M1, the user can learn that the cause is the cat's mischief, and is soothed by the mischievous behavior of the cat.

[0097] 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 feels an attachment to the cat.

[0098] 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 the mode change switch 63 OFF to end the cat mode, the control unit 100 changes the mode to the normal mode (S13: No → S1: No → S2). 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.

[0099] As described above, according to this embodiment, the following effects can be obtained. When the character image G2 on the screen M1 takes an action on a part of the sheet image G1, a part of the actual sheet 10 moves due to the electric device, so that the user can feel the presence of the cat more easily. 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 through the sheet 10 as if the cat is pushing the user, and can thus come into contact with the cat through the sheet 10.

[0100] By making the character image G2 an image resembling a cat, the user can have a soothing effect since he or she can come into contact 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.

[0101] 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 heat of the cat through the sheet 10.

[0102] When the control unit 100 executes the second control or the third control, when the user operates the operation unit, the electric device goes into an operating state that is not intended by the user, which can enhance entertainment value.

[0103] When the second control is executed, the seat back 12 or the seat 10 moves in a direction opposite to that when the first control is executed, which can enhance entertainment value.

[0104] Since the mode changeover switch 63 for switching between prohibition and permission of the second control is provided, the second control can be switched between prohibition and permission at the user's will.

[0105] In the cat mode, one control is selected from the first control, the second control, and the third control, so that the user does not know when the second control will be executed, thereby making the game more entertaining.

[0106] When the second control is selected in cat mode, the movement of the cat on screen M1 informs the user that the electric device is operating in an unintended operating state, which can provide comfort to the user.

[0107] When the first control is selected in cat mode, the cat moves the seat as the user intends, providing comfort to the user.

[0108] [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 change from the process of the control unit 100 according to the first embodiment, the same components and processes as those in the first embodiment are denoted by the same reference numerals and the description thereof will be omitted.

[0109] 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.

[0110] 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 of a navigation system, etc.

[0111] 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.

[0112] The acceleration sensor 72 has a function of detecting road conditions. Specifically, in this embodiment, the acceleration sensor 72 detects that the road on which the vehicle 70 is traveling or stopped is a slope.

[0113] 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, when the control unit 100 determines that the vehicle 70 is traveling on a curve or the road is a slope, it prohibits the operation of the electric device.

[0114] More specifically, the control unit 100 executes the process shown in Fig. 13. The process in Fig. 13 is the process in Fig. 4 to which new steps S31 to S36 have been added.

[0115] If the control unit 100 determines in step S5 that the reclining switch 61 has been operated (Yes), it determines whether the vehicle 70 is traveling around a curve or on a slope (S31) based on information from the camera 71 or the acceleration sensor 72. If it determines in step S31 that the vehicle 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 reclining mechanism 21. 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.

[0116] 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.

[0117] 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 is traveling around a curve or on a slope (Yes), the control unit 100 prohibits the operation of the electric slide mechanism 30 by selecting the third control (S32).

[0118] 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.

[0119] If the control unit 100 determines in step S10 that a 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 is determined 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.

[0120] As described above, according to the second embodiment, the following effects can be obtained. Since the operation of the electric device is prohibited when the vehicle 70 is traveling around a curve, movements that may cause discomfort to the user, such as the seat back 12 accidentally tilting backward while traveling around a curve, can be suppressed, thereby improving comfort.

[0121] When the vehicle 70 is located on a slope, the operation of the electric device is prohibited, so that movements that the user may find uncomfortable, such as the seat back 12 accidentally tilting backward while driving uphill, can be suppressed, thereby improving comfort.

[0122] The present invention is not limited to the above-described embodiment, but can be used in various forms as exemplified below.

[0123] 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.

[0124] 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 synchronization with the movement of the cat on the screen M1 jumping from the front seat. The control unit 100 slides the rear seat 10 backward by the electric sliding mechanism 30, tilts the seat back 12 of the rear seat 10 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.

[0125] According to this embodiment, the seats 10 are moved in accordance with the movement of the cat on the screen M1, which further enhances the entertainment value. If the seat system has multiple seats, a monitor may be provided for each seat. In this case, the monitor may be provided on the door next to the seat.

[0126] In the above embodiment, in the second control, the first electric device (e.g., electric reclining mechanism 21) corresponding to the first operation unit (e.g., reclining switch 61) is operated in the second operation 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 operated by the first operation unit, and move a character image according to the operation state of the second electric device.

[0127] 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 sliding mechanism 30. Note that, 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 an operating state in the second operating state, may be in an inoperating state, or may be in an operating state in the first operating state.

[0128] 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.

[0129] Also, for example, in the second control, the second electric device and the third electric device may be activated. 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.

[0130] According to this embodiment, when the second control is executed, two electric devices different from the first electric device are operated, which can enhance entertainment value.

[0131] The character image is not limited to a cat, and may be an image imitating an animal other than a human. The character image may also be an image imitating a human. Even if the character image is an image imitating a human, the control unit may move a part of the actual sheet with an electric device in accordance with the action of the person on the screen, such as tapping the sheet, so that the user can interact with the person on the screen through the sheet.

[0132] The character image may be an image smaller than the sheet image, or an image larger than the sheet image. When the character image is an image smaller than the sheet image, the character can be placed on the sheet, slipped under the sheet, or the like, and the variety of actions the character can take can be increased.

[0133] The positions and number of the electric devices are not limited to those in the above embodiment and can be changed as desired.

[0134] The electric device for moving at least a part 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.

[0135] The condition for the image sheet linking 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.

[0136] 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.

[0137] In the case of a vehicle capable of performing 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 while driving at high speed and prohibit the second control when not in auto-cruise. The control unit may also permit the second control while the vehicle is stopped and prohibit the second control while the vehicle is driving.

[0138] 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.

[0139] The image displayed on the screen is not limited to a seat image, and may be a user image that represents the user. In this case, when a character image takes an action on a part of the user image, the part of the seat that corresponds to the 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, and an air cell in a part of the seat back (the part that corresponds to the user's waist) may be expanded and contracted.

[0140] The electric device is not limited to the above embodiment, and may be, for example, a blower, a light, a device that generates a scent, a device that rotates the seat around a vertical axis, etc. If the seat is provided with a blower and the wind from the blower can be blown onto the user from the seat surface of the seat, the blower may be operated when the image shown in Fig. 9(a) is displayed on the screen M1. In this case, the wind from the blower can be used to create the impression of a cat breathing.

[0141] The function of executing the first control or the second control based on an operation command from an operation unit is not limited to a seat, 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 an air conditioner switch provided in the vehicle to increase the temperature, the set temperature can be configured to increase as usual when the first control is executed, and to decrease the set temperature when the second control is executed.

[0142] 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.

[0143] 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. Furthermore, the seat is not limited to a vehicle seat, and may be, for example, a seat chair, furniture or outdoor chair, hospital waiting chair, park bench, bed, mattress, etc.

[0144] 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.

[0145] 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.

[0146] 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, and the like. 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 front-back direction. In this case as well, 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.

[0147] 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 in a headlight and displays an image on the road surface.

[0148] 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.

[0149] For example, if the character is a bird, the electric devices (such as speakers and air cells) on the headrest and shoulders are 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 made 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 made lower than when the character is a mammal.

[0150] During auto-cruise, an image of a character operating the steering wheel may be displayed on the screen.

[0151] A positional relationship with surrounding vehicles may be detected by a sensor such as a camera, and the movement of the electric device may be restricted based on the positional relationship.

[0152] The control unit may control the operation of the driver's seat and the other seats differently during driving. For example, the driver's seat may be allowed to switch between the first mode and the second mode only when the vehicle is stopped, and the other seats may be allowed to switch between the first mode and the second mode at all times.

[0153] When the control unit detects a collision or predicts a collision, the control unit may stop the image display and operation in the second mode, and activate a safety device.

[0154] The amount of movement or speed of the part 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 is), the smaller the amount of movement or the slower the speed of the part of the seat. Note that, as the physique detection unit that detects the physique, for example, a pressure sensor that detects pressure from the seat surface, an electromagnetic wave sensor, a photographing device such as a camera, etc. can be used.

[0155] In addition, the electric device to be moved may 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 equal to or less than a predetermined value, and two air cells may be activated if the user's weight is greater than the predetermined value.

[0156] If the user's biological information is detected and fatigue is detected, the seat may move to recover from fatigue and an image may be displayed according to the movement. As a sensor for detecting the biological information, a sensor that detects at least one of brain waves, facial expressions, gaze, breathing, heart rate, pulse rate, etc. may be used. An example of the movement of the seat to recover from fatigue is a movement that massages the user by activating the air cells of the seat. An example of an image displayed according to the movement is a video of a cat rubbing a part of the user's body.

[0157] The control unit may suggest various modes to the user, such as a play mode, a fatigue recovery mode, a healing mode, and a sleep mode. When there are multiple seats, the mode may be switchable for each seat. In the healing mode or the sleep mode, the control unit may operate the air cells of the seat back in accordance with the user's breathing to induce the user to sleep. In the healing mode or the sleep mode, the control unit may display on the display unit a video of a cat alternately moving its left and right front paws to push the seat back from behind.

[0158] The character's movement and messages may be changed based on the user's brainwaves, facial expressions, line of sight, and breathing. The control unit may recommend to the user a character that matches the user's hobbies and preferences based on user information such as gender and age. The control unit may obtain user information from the user's smartphone, etc.

[0159] The control unit may distinguish the user based on the user information and change the voice output of the character according to the intimacy with the user. Note that the intimacy may be higher, for example, the longer the user has executed the cat mode. The control unit may make the character speak in a gentler manner as the intimacy is higher.

[0160] An illumination unit attached to the seat may operate in accordance with the display by the display unit or the operation of the seat.

[0161] The sheet can be produced, for example, by the following method. A manufacturing method for a seat comprising a first electric device and a second electric device that operate when electricity is applied, 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, wherein the control unit selects and executes a first control that puts the first electric device into a first operating state corresponding to the first operating command when it receives the first operating command from the first operating unit, and a second control that puts the first electric device into a second operating state that does not correspond to the first operating command and / or operates the second electric device when it receives the first operating command from the first operating unit, the manufacturing method for the seat comprising the steps of attaching the first electric device to a member that constitutes the seat, attaching the second electric device to a member that constitutes the seat, attaching the first operating unit to a member that constitutes the seat, and attaching the control unit to a member that constitutes the seat.

[0162] The elements described in the above-mentioned embodiment and modified examples may be implemented in any combination. [Explanation of symbols]
