Description

[Technical field]

[0001] The present invention relates to interior systems, seats and vehicle interior components. [Background technology]

[0002] 2. Description of the Related Art Conventionally, there has been known a device that estimates the seating posture of a seated person by mounting a pressure sensor or the like on a seat, which is an interior member of a vehicle (Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 11-064131 Summary of the Invention [Problem to be solved by the invention]

[0004] However, conventional seats have a problem in that they are not entertaining since they are only used to evaluate the driver's seated posture.

[0005] Therefore, an object of the present invention is to enhance the entertainment value of interior materials. [Means for solving the problem]

[0006] In order to solve the above problem, the interior system according to the present invention includes an interior member and a control unit. The interior member has a first portion, a second portion capable of sandwiching an object between the first portion and the second portion, an electric device that presses at least one of the first portion and the second portion toward the other, and a sensor that detects an object between the first portion and the second portion. The control unit controls the electric device based on information from the sensor. When the control unit determines that an object is present between the first portion and the second portion based on information from the sensor while the electric device is not in operation, the control unit operates the electric device to press at least one of the first portion and the second portion toward the other.

[0007] According to this configuration, when an object is placed between the first and second parts, the control unit operates the electric device to compress the object between the first and second parts, so that, for example, when a user places a finger between the first and second parts, the user feels as if someone has bitten the finger, or the user's belongings, such as a smartphone, can be held between the first and second parts. This increases the entertainment value of the interior member.

[0008] The interior system may further include a display unit capable of displaying an animal character, and the control unit may operate the electric device in accordance with the mouth movement of the character displayed on the display unit.

[0009] According to this configuration, for example, a user can place his / her finger between the first and second parts while looking at a character displayed on the display unit, thereby making the user feel as if the character is biting his / her finger.

[0010] Moreover, the sensor may be a pressure sensor that detects pressure between the first portion and the second portion, and the control unit may change the operation pattern of the electrically-driven device depending on the magnitude of the pressure obtained from the pressure sensor.

[0011] According to this configuration, for example, when pressure changes according to the movement of a user's finger placed between the first and second parts, the operating pattern of the electric device is changed according to the magnitude of the pressure, thereby enhancing entertainment value.

[0012] The sensor may be a biological information detection sensor that detects biological information, and the control unit may change the operation pattern of the electric device in accordance with the biological information acquired from the biological information detection sensor.

[0013] According to this configuration, the operation pattern of the electric device is changed according to biological information such as pulse rate and body temperature, thereby enhancing the entertainment value.

[0014] The seat according to the present invention also includes a pad and a skin covering the pad. The pad has a first portion, a second portion adjacent to the first portion, and a groove formed between the first portion and the second portion for suspending the epidermis. The seat further includes an electromotive device that urges at least one of the first portion and the second portion toward the other.

[0015] With this configuration, for example, when a user inserts a finger into the hanging groove of the seat, the electric device can be activated, making the user feel as if someone has bitten their finger, thereby enhancing the entertainment value of the seat as an interior component.

[0016] The seat according to the present invention includes a seat cushion and a seat back. The seat cushion has a first portion. The seat back has a second portion opposing the first portion. The seat further includes an electromotive device that urges at least one of the first portion and the second portion toward the other.

[0017] According to this configuration, for example, when a user places a finger between a first portion of the seat cushion and a second portion of the seat back, the electric device can be activated, making the user feel as if someone has bitten their finger, thereby enhancing the entertainment value of the seat as an interior component.

[0018] The seat according to the present invention includes a headrest and a seat back. The headrest has a first portion. The seat back has a second portion opposing the first portion. The seat further includes an electromotive device that urges at least one of the first portion and the second portion toward the other.

[0019] According to this configuration, for example, when a user places a finger between a first portion of the headrest and a second portion of the seat back, the electric device can be activated, making the user feel as if someone has bitten their finger, thereby enhancing the entertainment value of the seat as an interior component.

[0020] In addition, the vehicle interior member of the present invention includes a first portion, a second portion capable of sandwiching an object between the first portion and the second portion, and an electric device that presses at least one of the first portion and the second portion toward the other.

[0021] According to this configuration, for example, when a user places a finger between the first and second parts, the electric device can be activated, making the user feel as if someone has bitten their finger, thereby enhancing the entertainment value of the vehicle interior component.

[0022] At least one of the first portion and the second portion may include a sensor that detects an object between the first portion and the second portion when the electric device is not in operation.

[0023] According to this configuration, for example, the electric device can be operated when the sensor detects an object, so that the electric device can be operated or stopped depending on whether an object is inserted or removed between the first and second parts.

[0024] The sensor may also be a pressure sensor that detects pressure between the first location and the second location.

[0025] The sensor may also be a capacitance sensor that detects an object by a change in capacitance when the object enters an electric field.

[0026] The sensor may also be a resistive touch sensor.

[0027] At least one of the first portion and the second portion may have a heater.

[0028] According to this configuration, for example, by setting the heater temperature to a temperature equivalent to the body temperature of an animal, it is possible to make the user feel as if the animal has bitten his finger.

[0029] The vehicle interior member may also include a unit having the first portion, the second portion, and the electric device, and a base portion to which the unit is detachable.

[0030] This configuration makes it possible to easily replace the unit for clamping an object. Effect of the Invention

[0031] According to the present invention, when an object is placed between the first and second parts, the control unit activates the electric device to compress the object between the first and second parts, thereby enhancing the entertainment value of the interior component.

[0032] In addition, the control unit can operate the electric device in accordance with the mouth movement of the character displayed on the display unit, so that when the user places a finger between the first and second parts, the user can feel as if the character is biting the finger.

[0033] Furthermore, the control unit can change the operation pattern of the electric device depending on the magnitude of pressure between the first portion and the second portion, thereby enhancing entertainment value.

[0034] In addition, the control unit can change the operating pattern of the electric device in response to biological information such as pulse rate and body temperature, thereby enhancing the entertainment value.

[0035] In addition, by having at least one of the first and second parts have a sensor that detects a finger between the first and second parts, the electric device can be activated and stopped depending on whether an object is inserted or removed between the first and second parts.

[0036] Furthermore, by providing at least one of the first and second areas with a heater, for example by setting the temperature of the heater to a temperature equivalent to the body temperature of an animal, the user can feel as if the animal has bitten his finger.

[0037] Furthermore, by making the unit having the first section, the second section, and the electric device detachable from the base section, the unit can be easily replaced. [Brief description of the drawings]

[0039] [First embodiment] Hereinafter, a first embodiment of a seat system as an example of an interior system will be described with reference to the accompanying drawings. 1, the seat system 1 includes a seat 10 as an example of an interior member, 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 form a seat body on which a user can sit. The seat cushion 11, the seat back 12, and the headrest 13 each have a seat surface F that comes into contact with a seated user.

[0040] 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.

[0041] 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.

[0042] As shown in Fig. 2(a), 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 cushioning material such as urethane foam. The skin 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 skin.

[0043] The pad P of the seat cushion 11 has a first portion P1 and a second portion P2. The first portion P1 is located at the left-right end of the base portion 11A.

[0044] The second portion P2 is located at an inner end of the protruding portion 11B in the left-right direction. The second portion P2 is adjacent to the first portion P1 in the left-right direction.

[0045] A groove G for suspending the skin SK is formed between the first portion P1 and the second portion P2. The second portion P2 is capable of sandwiching an object between itself and the first portion P1.

[0046] The seat cushion 11 further includes a first air cell 21 and a second air cell 22 as an example of an electric device, a first pressure sensor 31 and a second pressure sensor 32 as an example of a sensor, and a first heater 41 and a second heater .

[0047] The first air cell 21 includes an inflatable / contractable bag 21A, and a pump and a tube (not shown). The pump has a function of feeding air into the bag 21A and sucking air out of the bag 21A, and is operated by passing electricity through it. The tube connects the bag 21A and the pump.

[0048] The bag 21A is embedded in the pad P. The pump is fixed to the frame of the seat 10, for example.

[0049] The second air cell 22 has a structure substantially similar to that of the first air cell 21, and includes a bag 22A, a pump, and a tube.

[0050] The bag 21A of the first air cell 21 is located within the base portion 11A. The bag 21A of the first air cell 21 is located inside the first portion P1 in the left-right direction. In other words, the first portion P1 is located between the bag 21A of the first air cell 21 and the second portion P2. This allows the first air cell 21 to press the first portion P1 toward the second portion P2 (see FIG. 2(b)).

[0051] The bag 22A of the second air cell 22 is located within the protruding portion 11B. The bag 22A of the second air cell 22 is located outside the second portion P2 in the left-right direction. In other words, the second portion P2 is located between the first portion P1 and the bag 22A of the second air cell 22. This allows the second air cell 22 to press the second portion P2 toward the first portion P1 (see FIG. 2(b)).

[0052] The first pressure sensor 31 and the second pressure sensor 32 are sensors that detect an object between the first portion P1 and the second portion P2. The first pressure sensor 31 and the second pressure sensor 32 detect the pressure between the first portion P1 and the second portion P2.

[0053] The first pressure sensor 31 is located in the first portion P1, and the second pressure sensor 32 is located in the second portion P2. In other words, the first portion P1 includes the first pressure sensor 31, and the second portion P2 includes the second pressure sensor 32.

[0054] The first heater 41 and the second heater 42 are heaters that heat the area between the first portion P1 and the second portion P2. The first heater 41 is located in the first portion P1, and the second heater 42 is located in the second portion P2. In other words, the first portion P1 has the first heater 41, and the second portion P2 has the second heater 42.

[0055] More specifically, the first heater 41 is positioned between the bag 21A of the first air cell 21 and the first pressure sensor 31. The second heater 42 is positioned between the bag 22A of the second air cell 22 and the second pressure sensor 32.

[0056] Returning to FIG. 1, the seat 10 further includes a mode changeover switch SW. The mode changeover switch SW is a switch for changing the mode of the control unit 100 between a first mode and a second mode. The mode changeover switch SW is, for example, a push button type switch. The mode changeover switch SW alternates between an ON state and an OFF state every time the mode changeover switch SW is pressed by the user.

[0057] 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.

[0058] 3, the control unit 100 is connected to the monitor M, the pressure sensors 31, 32, the mode changeover switch SW, the air cells 21, 22, and the heaters 41, 42. The monitor M is capable of displaying a dog character as shown in FIG.

[0059] The control unit 100 controls the air cells 21, 22 based on information from the pressure sensors 31, 32. In detail, when the control unit 100 determines that an object is present between the first portion P1 and the second portion P2 based on information from the pressure sensors 31, 32 while the air cells 21, 22 are not in operation, the control unit 100 activates the air cells 21, 22 to press the first portion P1 against the second portion P2 and press the second portion P2 against the first portion P1.

[0060] The control unit 100 can be switched between a first mode and a second mode by a mode switching switch SW. The first mode is a mode in which the air cells 21, 22 do not operate even if the user inserts a finger between the first part P1 and the second part P2. In the following description, the first mode is also referred to as a "normal mode."

[0061] The second mode is a mode in which, when the user places a finger between the first part P1 and the second part P2, the air cells 21 and 22 are activated in accordance with a video of a dog biting a user's finger displayed on the screen M1 of the monitor M shown in Fig. 6, thereby making the user feel as if the dog is gently biting the finger. In the following description, the second mode is also referred to as a "gentle bite mode." In the gentle bite mode, the control unit 100 activates the air cells 21 and 22 in accordance with the movement of the mouth of the character displayed on the monitor M.

[0062] 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 change switch SW is ON (S1). If it is determined in step S1 that the mode change switch SW 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.

[0063] When it is determined in step S1 that the mode changeover switch SW is ON (Yes), the control unit 100 sets the mode to the second mode, i.e., the soft bite mode (S3), and displays the home screen shown in Fig. 5 on the screen M1 (S4). After step S4, the control unit 100 determines whether the mode changeover switch SW is ON (S5).

[0064] If it is determined in step S5 that the mode switching switch SW is ON (Yes), the control unit 100 determines whether or not at least one of the two pressure sensors 31, 32 is ON (S6). Here, the pressure sensor being ON means that the pressure value detected by the pressure sensor is equal to or greater than the first threshold value. If it is determined in step S5 that the mode switching switch SW is not ON (No), the control unit 100 proceeds to the process of step S2.

[0065] If it is determined in step S6 that at least one of the pressure sensors 31, 32 has been turned ON (Yes), the control unit 100 displays an image of a dog biting a finger on the screen M1 (S7), as shown in FIG. 6. After step S7, the control unit 100 turns on the heaters 41, 42 (S8). Specifically, in step S8, the control unit 100 may control the heaters 41, 42 so that the temperature between the first portion P1 and the second portion P2 becomes close to the body temperature of the dog. In this case, for example, a temperature sensor that detects the temperature between the first portion P1 and the second portion P2 may be provided in the seat 10, and the control unit 100 may control the heaters 41, 42 so that the temperature acquired by the control unit 100 from the temperature sensor becomes the target temperature.

[0066] After step S8, the control unit 100 displays on the screen M1 a video of the dog moving its mouth as if biting the finger (S9). After step S9, the control unit 100 activates the air cells 21, 22 in accordance with the movement of the dog's mouth on the screen M1 (S10). In detail, the control unit 100 controls the pumps of the air cells 21, 22 so that the bags 21A, 22A inflate when the dog's mouth on the screen M1 moves in a closing direction, and the bags 21A, 22A deflate when the dog's mouth on the screen M1 moves in an opening direction.

[0067] After step S10, the control unit 100 determines whether the mode switching switch SW is ON (S11). If it is determined in step S11 that the mode switching switch SW is ON (Yes), the control unit 100 returns to the process of step S6.

[0068] If it is determined in step S11 that the mode changeover switch SW is not ON (No), the control unit 100 stops the heaters 41, 42 and the air cells 21, 22 (S12) and proceeds to the process of step S2. If it is determined in step S6 that neither of the pressure sensors 31, 32 is ON (No), the control unit 100 stops the heaters 41, 42 and the air cells 21, 22 (S13) and returns to the process of step S4. When stopping the air cells 21, 22 in steps S12 and S13, the control unit 100 stops the operation of the pump after deflatating the bags 21A, 22A to the maximum.

[0069] Next, a specific example of the operation of the control unit 100 will be described. As shown in Fig. 1, when a user seated on the seat 10 turns on the mode change switch SW, the control unit 100 starts the soft bite mode and displays the home screen shown in Fig. 5 on the screen M1 of the monitor M (S1: Yes → S3 → S4). Note that the home screen may display a message or image encouraging the user to take an action, such as "Put your finger in the hanging groove on the right side."

[0070] 2(b), when the user places a finger in the groove G during the gentle bite mode, the first part P1 and the second part P2 are pushed outward to the left and right, and the pressure sensors 31, 32 are turned ON. Note that when the finger is inserted into the groove G, the air cells 21, 22 are not yet activated, and therefore the pressure sensors 31, 32 detect the finger between the first part P1 and the second part P2 in the state in which the air cells 21, 22 are not activated.

[0071] When the control unit 100 determines that the finger has entered the groove because the pressure sensors 31, 32 are turned ON, it turns on the heaters 41, 42 and displays a video of a dog gently biting the finger as shown in Figure 6 on the screen M1 of the monitor M, and activates the air cells 21, 22 in accordance with the movement of the dog's mouth on the screen M1 (S6: Yes → S7 to S10).

[0072] When the user removes his or her finger from the groove, pressure sensors 31, 32 turn OFF (pressure value becomes less than the first threshold value), so control unit 100 stops heaters 41, 42 and air cells 21, 22 and returns the display of screen M1 to the home screen (S6: No→S13→S4).

[0073] When the user turns off the mode changeover switch SW during the gentle bite mode, the control unit 100 determines No in step S5 or step S11 and returns the mode to the normal mode (S2).

[0074] As described above, according to this embodiment, the following effects can be obtained. When a finger is inserted between the first portion P1 and the second portion P2, the control unit 100 activates the air cells 21, 22 to compress the finger between the first portion P1 and the second portion P2, thereby enhancing the entertainment value of the seat 10.

[0075] The air cells 21 and 22 are activated in accordance with the movement of the dog's mouth displayed on the monitor M, so that the user can feel that the dog is biting his / her finger, thereby providing relief to the user.

[0076] Since the air cells 21, 22 are activated on the condition that the pressure sensors 31, 32 detect a finger, the air cells 21, 22 can be activated or deactivated in response to the insertion or removal of the finger between the first portion P1 and the second portion P2.

[0077] The heaters 41 and 42 can make the temperature inside the groove G equal to the body temperature of the dog, so that the user can realistically feel the dog biting his finger.

[0078] The present invention is not limited to the above-described embodiment, but can be used in various forms as exemplified below. In the following description, the same reference numerals are used to designate components having substantially the same structures as those in the above-described embodiment, and the description thereof will be omitted.

[0079] The first and second regions capable of pinching an object are not limited to the regions forming the hanging groove as in the above embodiment. For example, as shown in FIG. 7, the first region P11 may be a part of the pad P of the seat cushion 11, and the second region P12 facing the first region P11 may be a part of the pad P of the seat back 12. In this case, the seat cushion 11 may have the first region P11 and the first air cell 21, the first pressure sensor 31, and the first heater 41 described above. The seat back 12 may have the second region P12 and the second air cell 22, the second pressure sensor 32, and the second heater 42 described above.

[0080] Even in this form, when a user places a finger between the first portion P11 of the seat cushion 11 and the second portion P12 of the seat back 12, the air cells 21, 22 are activated, making the user feel as if the dog has bitten his finger, thereby enhancing the entertainment value of the seat 10.

[0081] Also, for example, the first portion P21 may be a part of the pad P of the headrest 13, and the second portion P22 facing the first portion P21 may be a part of the pad P of the seat back 12. In this case, the headrest 13 may have the first portion P21, as well as the first air cell 21, the first pressure sensor 31, and the first heater 41 described above. The seat back 12 may have the second portion P22, as well as the second air cell 22, the second pressure sensor 32, and the second heater 42 described above.

[0082] Even in this form, when a user places a finger between the first portion P21 of the headrest 13 and the second portion P22 of the seat back 12, the air cells 21, 22 are activated, making the user feel as if the dog has bitten his finger, thereby enhancing the entertainment value of the seat 10.

[0083] The display unit is not limited to the monitor M, and may be, for example, a projection device 50 as shown in FIG. 7. The projection device 50 projects an image of a dog character onto the surface of the seat 10 as shown in FIG. 8. In this case, it is preferable to project an image of the dog's face across the headrest 13 and the seat back 12 so that the mouth of the dog projected onto the surface of the seat 10 from the projection device 50 is located between the first portion P21 and the second portion P22. In this embodiment, as in the above embodiment, by operating the air cells 21 and 22 in accordance with the movement of the mouth of the dog projected onto the surface of the seat 10, the user can feel more realistically that the dog is gently biting his finger.

[0084] The unit for clamping an object may have at least the first portion, the second portion, and the electric device, and may not have the sensor and the heater. In the absence of a sensor, the electric device may be operated by a user operating an operating member (e.g., a start switch of the electric device).

[0085] The seat having the unit may be an interior component for a vehicle constituting the interior of a vehicle, as shown in Fig. 9. In this case, the seat having the unit may be a first row seat 10A, a second row seat 10B, or a third row seat 10C. The groove between the first and second regions may be disposed, for example, on the seating surfaces indicated by dots of the seats 10A to 10C.

[0086] The unit may be provided in a vehicle interior member other than a seat. Examples of vehicle interior members on which the unit may be provided include a vehicle floor 61, a dashboard 62, an inner panel 63 of a door or a vehicle side wall, a roof 64, and a cover 65 for opening and closing a sunroof. The groove between the first portion and the second portion may be disposed on a surface indicated by dots in the figure. The vehicle interior member may also be a steering wheel, a console, an instrument panel, etc.

[0087] 10, the first portion P1 may have a first plate member 71 that is harder than the skin SK, and the second portion P2 may have a second plate member 72 that is harder than the skin SK.

[0088] The first plate member 71 is located between the groove G and the first pressure sensor 31. The second plate member 72 is located between the groove G and the second pressure sensor 32. Each of the plate members 71, 72 has a surface facing the groove G, and each of the upper and lower ends is bent in a direction away from the groove G.

[0089] The first and second parts are not limited to parts of the pad, and may be, for example, parts of the plate members 71 and 72 or the air cell sack described above. If the first and second parts are parts of the plate members or the air cell sack, they are harder than the seat cover, so the user is more likely to feel the pressure. The hard member harder than the seat cover may be curved or may be a flat plate member.

[0090] The first or second part may have a static electricity removing pad that comes into contact with an object placed between the first and second parts. In this case, for example, when a finger is placed between the first and second parts, static electricity can be removed from the finger. The first or second part may also have an abrasive that comes into contact with an object placed between the first and second parts. In this case, for example, when a finger is placed between the first and second parts, the abrasive can be used to polish nails.

[0091] 11 , the unit U for holding an object may be provided in the headrest 13 or in the seat back 12. When the unit U is provided in the headrest 13, the groove G may open, for example, from the left and right side surfaces of the headrest 13. When the unit U is provided in the seat back 12, the groove G may open, for example, from the rear surface of the seat back 12.

[0092] The unit may be provided on the front end, the underside of the front end, or the side of the front end of the seat or the armrest of the door. The unit may also be provided on the protruding portion of the seat, the groove of the seat back, or the back of the headrest.

[0093] 12(a) and 12(b), one portion (for example, the second portion P2) may be provided with a plurality of sensors 81 to 84. The sensors 81 to 84 are sensors that detect an object that has entered the groove G, and are, for example, pressure sensors.

[0094] In this case, the control unit may change the operation pattern of the air cell 22 based on information from each of the sensors 81-84. Specifically, for example, a first threshold for determining that an object has entered between the first portion P1 and the second portion P2 may be set to a different value for each of the sensors 81-84. The control unit may determine whether or not the pressure value has reached the first threshold for each of the sensors 81-84, and may change the number of times the object is pinched between the first portion P1 and the second portion P2 or the pinching time from when the pressure on the object reaches its maximum to when it reaches its minimum, depending on the number and locations of the sensors whose pressure values ​​have reached the first threshold.

[0095] For example, when the control unit determines that the pressure values ​​at the first sensor 81 and the third sensor 83 are equal to or greater than the first threshold value, the control unit sets the number of times of pinching to a predetermined number and makes the pinching time longer than in other cases. In this control, the control unit may make the pinching speed slower than in other cases. Furthermore, when the control unit determines that the pressure values ​​at the second sensor 82 and the third sensor 83 are equal to or greater than the first threshold value, the control unit may alternate between strong nip control in which the maximum value of the pressure applied to the object is a first maximum value and weak nip control in which the maximum value of the pressure applied to the object is a second maximum value that is smaller than the first maximum value.

[0096] 13, the seat cushion 11 may include a unit U having a first portion P1, a second portion P2, and air cells 21, 22 (bags 21A, 22A), and a base portion B1 to which the unit U can be detached. In this case, for example, the inner panel IP of the door D may have a base portion B2 to which the unit U can be detached. The base portions B1, B2 may have recesses B11, B21, respectively, into which the unit U can be fitted.

[0097] In this structure, the tubes of the air cells 21, 22 are disposed in the unit U and the bases B1, B2, and the tubes on the unit U side and the tubes on the bases B1, B2 side are detachable via joints. If the unit U has a sensor, wiring connecting the sensor and the control unit is disposed in the unit U and the bases B1, B2, and the wiring on the unit U side and the wiring on the bases B1, B2 side are detachable via connectors. The unit U may or may not have a skin SK.

[0098] According to this configuration, since the unit U can be attached to the seat 10 and the door D, for example, when the unit U holds the user's belongings such as a smartphone SP, the user can move the belongings together with the unit U and place the belongings in a desired position. Also, the user can place the unit U in a desired position and enjoy the gentle bite mode. Also, since the unit U is detachable from the base parts B1 and B2, the unit replacement work can be easily performed.

[0099] The unit that is detachable from the base may include a first section, a second section, a sensor, an electric device, a control section, and a battery. According to this configuration, the unit can be detached from the base and used independently. In this case, a contact or non-contact charger for charging the battery of the unit may be provided on the base.

[0100] The electric device may be any device capable of pressing one of the first part and the second part toward the other, and may be, for example, a link mechanism, a cylinder, a solenoid, a cam rotated by a motor, etc. The electric device may also be a structure having a vice-like mechanism that clamps both the first part and the second part.

[0101] 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.

[0102] The control unit may change the operation pattern of the electric device according to the magnitude of the pressure acquired from the pressure sensor. For example, the control unit may set the maximum pressure applied by the electric device to the object as a first pressure value when the pressure acquired from the pressure sensor is smaller than a second threshold, and set the maximum pressure applied by the electric device to the object as a second pressure value larger than the first pressure value when the pressure acquired from the pressure sensor is equal to or larger than the second threshold. Here, the second threshold is larger than the first threshold for determining that the object has entered between the first portion and the second portion. Note that the second pressure value may be a value smaller than the first pressure value.

[0103] With this configuration, when the pressure changes in accordance with the movement of the user's finger placed between the first and second parts, the operating pattern of the electric device changes depending on the magnitude of the pressure, thereby enhancing the entertainment value.

[0104] The sensor may be a capacitance sensor that detects an object based on a change in capacitance when the object enters an electric field, or may be a resistive touch sensor.

[0105] The sensor may be a biological information detection sensor that detects biological information. In this case, the control unit may change the operation pattern of the electric device in accordance with the biological information acquired from the biological information detection sensor.

[0106] Examples of the biological information include pulse waves, blood oxygen concentration, heart rate, blood pressure, blood sugar level, pulse, body temperature, sweat, etc. For example, the control unit may obtain the pulse rate from the biological information detection sensor, and may decrease the maximum pressure that the electric device applies to the object as the obtained pulse rate increases, or may increase the maximum pressure as the obtained pulse rate increases.

[0107] According to this configuration, the operation pattern of the electric device is changed according to biological information such as pulse rate and body temperature, thereby enhancing the entertainment value.

[0108] The interior member is not limited to an interior member for a vehicle that constitutes the interior of a vehicle, but may be, for example, an interior member for a room. The interior member for a vehicle is not limited to an interior member for a car, but may be, for example, an interior member for other vehicles such as a ship or an aircraft.

[0109] The determination of whether or not there is an object between the first and second parts may be made by determining that there is an object between the first and second parts when the condition for detecting an object by a sensor and the condition for the electric device to be OFF are satisfied.

[0110] The characters may be non-animal characters, humans, fantasy creatures, cartoon characters, and the like.

[0111] In the above embodiment, one electric device, one sensor, and one heater are provided for each of the first and second parts, but an electric device, a sensor, and a heater may be provided for only one of the members of the first and second parts. Also, the electric device, the sensor, and the heater may be arbitrarily allocated and installed in the first and second parts. For example, an electric device may be installed in the first part, and a sensor and a heater may be installed in the second part.

[0112] The projection device may be mounted on the vehicle's ceiling, door, center console, or seat. The operation pattern of the electric device may be changed according to the intimacy between the vehicle occupant and the character displayed on the display unit, the carefulness of driving, and the like. For example, the operation pattern may be changed so that the pressure of the first and second parts is lower as the intimacy is higher. Also, the operation pattern may be changed so that the pressure of the first and second parts is lower as the driving is more careful. The intimacy may be set to be higher the more the number of times the soft bite mode is executed. The carefulness of driving may be set to be higher the slower the operating speed of at least one of the accelerator operation, brake operation, and steering operation.

[0113] In the above embodiment, the sides of the groove between the first and second parts into which an object can enter are in close contact with each other, but the sides of the groove between the first and second parts may be separated. In other words, there may be a gap between the two surfaces for sandwiching the object. In this case, the maximum distance between the two surfaces is preferably 2 cm or less. This allows small objects such as a smartphone or a finger to be appropriately sandwiched between the two surfaces.

[0114] The depth of the groove between the first and second portions may be large enough to accommodate up to the first or second joint of a finger.

[0115] The sensor may function as an operation input unit for operating the device. In other words, the control unit may operate the device based on information from the sensor. The device may be an electric reclining mechanism for tilting the seat back, an electric sliding mechanism for moving the seat forward / backward or left / right, a display unit, etc.

[0116] The control unit may operate an audio output unit (such as a headrest speaker or in-car audio) in accordance with the operation of the electric device. For example, a sound such as "bite biting" may be output in accordance with the action of pinching the finger between the first part and the second part.

[0117] The interior system or the interior member may include a fingerprint authentication unit. In this case, for example, the control unit may determine whether or not the user is a fingerprint-registered user based on information from the fingerprint authentication unit, and when it is determined that the user is a registered user, it may permit the pinch control of pinching an object between the first part and the second part, and when it is determined that the user is not a registered user, it may prohibit the pinch control. Note that the fingerprint may be registered, for example, from the screen of a navigation system or a smartphone.

[0118] The number of times of pinching control (for example, the number of times the pressure between the first and second parts was increased and then decreased) may be stored, and the action of the character displayed on the display unit may be changed according to the number of times. For example, as the number of times increases, a display may be made showing that the cat's stomach is getting full, and the pressure between the first and second parts may become stronger.

[0119] Examples of manufacturing methods for the interior system include the following methods. A manufacturing method for an interior system comprising: an interior member having a first portion, a second portion capable of sandwiching an object between the first portion, an electric device that presses at least one of the first portion and the second portion toward the other, and a sensor that detects an object between the first portion and the second portion; and a control unit that controls the electric device based on information from the sensor, wherein when the control unit determines that an object is present between the first portion and the second portion based on information from the sensor when the electric device is not operating, the control unit operates the electric device to press at least one of the first portion and the second portion toward the other, the manufacturing method for an interior system comprising the steps of: attaching the electric device corresponding to at least one of the first portion and the second portion; attaching the sensor at a position where the object can be detected; and connecting the electric device and the sensor to the control unit.

[0120] The sheet can be produced, for example, by the following method. A method for manufacturing a sheet comprising a pad and a skin covering the pad, the pad having a first portion, a second portion adjacent to the first portion, and a groove formed between the first portion and the second portion for suspending the skin, and further comprising an electric device for pressing at least one of the first portion and the second portion toward the other, the method comprising a step of arranging the electric device within the pad so that the electric device is positioned at a position corresponding to at least one of the first portion and the second portion.

[0121] When the hanging groove is formed between a base portion located in the left-right center and an extension portion located on the left-right outer side of the base portion, with the extension portion extending further toward the user than the base portion, in the manufacturing method of the seat, the electric device may be positioned within the base portion or the extension portion.
