[0002] As this type of device, there is known a device that outputs an alarm based on the sitting posture, sitting time or the like of a user sitting on a chair, and notifies the user of such information (see, for example, Patent Document 1). In the device described in Patent Document 1, for example, an alarm is output when the sitting time is equal to or longer than a predetermined time. [[Prior Art Documents]] [[Patent Documents]]

[0003] [[Patent Document 1]] Japanese Patent Laid-Open No. 2019-014444 [[Summary of the Invention]] [[Problem to be Solved by the Invention]]

[0004] However, although the device described in Patent Document 1 above describes that the alarm may be output by vibrating the alarm portion, there is no description regarding the arrangement position of the alarm portion that vibrates. Depending on the arrangement position of the alarm portion in the device, the presence of the alarm portion may give the user a feeling of a foreign object. [[Means for Solving the Problem]]

[0005] To solve the above problems, the cushion device according to claim 1 comprises: a cushion part that supports the buttocks of a seated user; a vibration device that provides vibration to the user seated on the cushion part; a control device that drives the vibration device based on the seating time of the user seated on the cushion part; and a storage bag capable of storing the cushion part and the vibration device, wherein the storage bag has a storage bag body capable of storing the cushion part and a handle part provided to make the storage bag body portable, and the vibration device is stored in the handle part and provides vibration to the user seated on the cushion part via the handle part.

[0006] According to the invention of claim 1, the vibration device is housed in the handle portion and the vibration is transmitted to the user sitting on the cushion portion via the handle portion. As a result, the vibration device does not come into contact with the buttocks of the user sitting on the cushion portion, and it is possible to suppress the feeling of a foreign object being present in the user sitting on the cushion portion.

[0007] The invention according to claim 2 is a cushioning device according to claim 1, wherein the storage bag further comprises an auxiliary bag capable of storing the control device, and the auxiliary bag is provided connected to the main body of the storage bag.

[0008] According to the invention of claim 2, since the control device for controlling the vibration device is housed in an auxiliary bag separate from the main storage bag body that houses the cushion, the control device does not come into direct or indirect contact with the buttocks of the user sitting on the cushion, thus preventing the cushion device from causing the user to feel a foreign object. Furthermore, since the auxiliary bag for housing the control device is attached to the main storage bag body, the cushion device can be carried as a single unit.

[0009] The invention according to claim 3 is a cushioning device according to claim 2, characterized in that the auxiliary bag is connected to the storage bag body via a foldable flap portion.

[0010] According to the invention of claim 3, when the cushion is placed on a chair, the control device can be positioned hanging from the cushion to the side of the chair via the flap, thus making the cushion device more compact when in use. Furthermore, by positioning the control device facing the cushion via the flap, the cushion device can be made more compact for easy transport.

[0011] The invention according to claim 4 is a cushioning device according to claim 3, wherein the control device and the vibration device are wired together via a cable, and the flap portion has an insertion portion through which the cable can be inserted.

[0012] According to the invention of claim 4, the control device and the vibration device are wired together using a cable inserted through the inside of the flap portion, so the cable is not exposed to the outside, which improves the portability and usability of the cushioning device.

[0013] The invention according to claim 5 is characterized in that, in the cushioning device described in claim 3, the device further comprises a fixing part for fixing the auxiliary bag, which is facing the storage bag body via the flap part, to the storage bag body.

[0014] According to the invention of claim 5, the storage bag body and the auxiliary bag, that is, the cushion part and the control device, can be fixed in a position facing each other, thereby enabling miniaturization of the cushion device and improving portability.

[0015] The invention according to claim 6 is a cushioning device according to claim 1, characterized in that the control device stops the operation of the vibration device regardless of the user's seating time, based on a preset user schedule.

[0016] According to the invention of claim 6, the operation of the vibration device can be limited in advance in environments where it is undesirable to operate the vibration device, such as during a meeting. For example, since the limited time is set in advance based on a schedule, even if the user forgets to set the limited time, it is possible to prevent the vibration device from operating in environments where it is not desired.

[0017] The invention according to claim 7 is a cushion device according to claim 1, further comprising a seating sensor for detecting when a user sits on the cushion and a timer for counting the seating time, wherein the control device drives the vibration device when the seating sensor detects a seated state for a predetermined time or longer, resets the timer's count for the predetermined time if the seated state is not detected for a certain period of time or longer during the count for the predetermined time, and continues counting for the predetermined time if the time during which the seated state is not detected is less than a certain period of time.

[0018] According to the invention of claim 7, since actions such as readjusting one's position or temporarily standing up are excluded from the count of a predetermined time, the actual sitting time can be counted. [Effects of the Invention]

[0019] According to the present invention, a vibration device can be installed without causing a foreign body sensation to the user sitting on the cushion. [Brief explanation of the drawing]

[0021] Hereinafter, an embodiment of the present invention will be described with reference to FIG. 1 to FIG. 6. A cushion device according to an embodiment of the present invention can be suitably used for a single-seat chair with a backrest such as an office chair, and can also be used for single-seat sofas, vehicle seats, and the like in addition to the above. Hereinafter, an example in which the cushion device is used for an office chair (hereinafter simply referred to as a chair) will be described as an example of the cushion device. In the following description, the front-rear direction, the left-right direction (width direction), and the up-down direction (height direction) are defined based on a user sitting on a chair to which the cushion device is attached, and the configuration of each part will be described in accordance with these definitions.

[0022] FIG. 1 is a perspective view of a chair to which a cushion device according to an embodiment of the present invention is attached. As shown in FIG. 1, the chair includes a seating portion that supports a user's buttocks, thighs, and the like, a backrest portion that supports the user's lumbar region, back, and the like, and a caster portion that movably supports the seating portion.

[0023] The seating portion includes a substantially rectangular plate-shaped seating frame along the outer shape of the seating portion, a pad portion made of a cushion material such as urethane foam, and a skin material made of cloth, synthetic leather, or the like, and is formed by attaching the pad portion to the seating frame and covering these with the skin material.

[0024] Similar to the seating portion, the backrest portion includes a substantially rectangular plate-shaped backrest frame along the outer shape of the backrest portion, a pad portion made of a cushion material such as urethane foam, and a skin material made of cloth, synthetic leather, or the like, and is formed by attaching the pad portion to the backrest frame and covering these with the skin material.

[0025] The caster section 13 has an extendable section 13a that is configured to extend and retract in the vertical direction, a plurality of legs 13b that extend radially from the lower end of the extendable section 13a, and a plurality of casters 13c provided at the tip of each of the plurality of legs 13b, and is configured to move forward, backward, left and right by rolling the plurality of casters 13c.

[0026] The seat portion 11 is attached to the upper end of the caster portion 13, and the backrest portion 12 is attached to the rear end of the seat portion 11 via a flexible connecting member (not shown). The backrest portion 12 is tiltable using the flexibility of the connecting member.

[0027] Figure 2 is a plan view showing the main components of the cushion device 2 according to this embodiment. As shown in Figure 2, the cushion device 2 comprises a cushion section 21 that supports the buttocks and thighs of a seated user, a plurality of seating sensors 22 that detect when a user sits on the cushion section 21, a timer (see Figure 5, described later) 23 that counts (detects) the seating time of a user sitting on the cushion section 21, a vibration device 24 that applies vibration to the user sitting on the cushion section 21, a control device 25 that drives the vibration device 24 based on the seating time of the user counted by the timer 23, and a storage bag 26 that houses these components.

[0028] The cushion portion 21 has a pad portion 21a made of a cushioning material such as urethane foam that is roughly rectangular in shape when viewed from above, and a surface material 21b made of fabric or synthetic leather, and is formed by covering the pad portion 21a with the surface material 21b. However, from the viewpoint of being stored in the storage bag 26, the cushion portion 21 may also consist only of the pad portion 21a.

[0029] Figure 3 is a diagram showing the arrangement of multiple seat sensors placed in the cushion portion according to this embodiment. As shown in Figure 3, each of the multiple seat sensors 22 is formed in a substantially rectangular shape and is arranged at predetermined intervals on the upper surface of the cushion portion 21. Specifically, the multiple seat sensors 22 are composed of three pairs of seat sensors (hereinafter referred to as seat sensor pairs) 22, 22 arranged symmetrically on the left and right sides around a center line CL1 extending in the front-rear direction, and these pairs are arranged in a row in the front-rear direction. The first seat sensor pair 22a is placed in front of the cushion portion 21, the second seat sensor pair 22b is placed behind the first seat sensor pair 22a, and the third seat sensor pair 22c is placed behind the second seat sensor pair 22b, i.e., at the rear of the cushion portion 21.

[0030] Each of the first to third seat sensor pairs 22a to 22c is positioned such that the distance between the centerlines CL2 extending in the left-right direction (hereinafter referred to as the center-to-center distance) is different. For example, each of the first to third seat sensor pairs 22a to 22c is positioned such that the first center-to-center distance a between the first seat sensor pair 22a and the second seat sensor pair 22b is shorter than the second center-to-center distance b between the second seat sensor pair 22b and the third seat sensor pair 22c (first center-to-center distance a < second center-to-center distance b).

[0031] Furthermore, each of the first to third seat sensor pairs 22a to 22c is arranged such that the distance between the seat sensors differs. For example, the first distance c between the seat sensors 22 in the first seat sensor pair 22a is shorter than the third distance e between the seat sensors 22 in the third seat sensor pair 22c, and the third distance e between the seat sensors 22 in the third seat sensor pair 22c is shorter than the second distance d between the seat sensors 22 in the second seat sensor pair 22b, thus each of the first to third seat sensor pairs 22a to 22c is arranged in this manner (first distance c < third distance e < second distance d).

[0032] By arranging the first to third seating sensor pairs 22a to 22c in this manner, for example, the third seating sensor pair 22c can detect the seating pressure of the user's buttocks, and the first and second seating sensor pairs 22a and 22b can detect the seating pressure of the user's thighs. When each of the first to third seating sensor pairs 22a to 22c detects the user's seating (seating pressure), it transmits a seating signal to the control device 25. Note that each of the first to third seating sensor pairs 22a and 22b can be a general seating sensor that detects the presence or absence of seating pressure, so a detailed explanation is omitted here.

[0033] When Timer 23 receives a count start signal from Control Device 25, it starts counting and outputs the counted time information to Control Device 25. When Timer 23 receives a count stop signal from Control Device 25, it stops counting, and when it receives a count restart signal, it resumes counting. Furthermore, when Timer 23 receives a count reset signal from Control Device 25, it resets the counted time information.

[0034] The vibration device 24 starts vibrating when it receives a drive signal from the control device 25, and stops vibrating when it receives a drive stop signal. The vibration device 24 is also wired to the control device 25 by a cable 27, and the drive signal and power are supplied from the control device 25 via the cable 27. The vibration device 24 may be a battery-powered type that does not receive power from the control device 25, and in this case, the vibration device 24 and the control device 25 may be electrically connected wirelessly.

[0035] The control device 25 is housed in a rectangular box-shaped enclosure and drives and controls the vibration device 24 based on information output from the first to third seating sensor pairs 22a to 22c and the timer 23. The control device 25 will be described in detail later.

[0036] The storage bag 26 comprises a storage bag body 261 capable of storing the cushion portion 21 on which the first to third seating sensor pairs 22a to 22c are arranged, a handle portion 262 capable of storing the vibration device 24, an auxiliary bag 263 capable of storing the control device 25, a hook-and-loop fastener (fixing portion) 264 for fixing the auxiliary bag 263 to the storage bag body 261, a flap portion 265 for connecting the storage bag body 261 and the auxiliary bag 263, and a pair of band portions 266, 266 for fixing the storage bag body 261 to the seat portion 11 of the chair 1.

[0037] The storage bag body 261 is formed in a rectangular shape that is substantially the same as the outer shape of the cushion part 21, and is designed to allow storage of the cushion part 21 without deformation. The storage bag body 261 is made of fabric, and on the back surface opposite to the seating surface, there is a loop surface (female) that can engage with the hook surface (male) of the hook fastener 264 provided on the auxiliary bag 263. The loop surface (female) may be provided over the entire back surface of the storage bag body 261, or it may be provided only in corresponding locations.

[0038] The handle portion 262 is attached to one side of the roughly rectangular storage bag body 261 and is hollow in shape so that the vibrator 24 can be inserted into it. The hollow handle portion 262 is attached to the storage bag body 261 so as to communicate with the inside of the storage bag body 261, and the cable 27 connected to the vibrator 24 housed in the handle portion 262 is connected from the handle portion 262 to the storage bag body 261 and the flap portion 265, and then to the control device 25 housed in the auxiliary bag 263.

[0039] The auxiliary bag 263 is formed in a rectangular shape that is substantially the same as the external shape of the control device 25, and is designed to accommodate the control device 25. A zipper portion 263a is provided on one side of the auxiliary bag 263, and the control device 25 can be inserted into and removed from the auxiliary bag 263 via the zipper portion 263a. Figure 4 shows a hook-and-loop fastener 264 attached to the auxiliary bag 263 that stores the control device 25. The auxiliary bag 263 is made of fabric, and as shown in Figure 4, a hook-and-loop fastener (hook side) 264 is provided on the opposite side that can face the back surface of the storage bag body 261 via a flap portion 265. The auxiliary bag 263 is configured to be able to be joined to the back surface of the storage bag body 261 via the hook side of the hook-and-loop fastener 264.

[0040] The flap portion 265 is formed in a rectangular shape from a flexible fabric material and is attached to one side of the storage bag body 261 to which the handle portion 262 is attached, intersecting with one side. By attaching the flap portion 265 to one side of the storage bag body 261 to which the handle portion 262 is attached, for example, if the cushion device 2 is positioned so that the handle portion 262 is located behind the seat portion 11 (towards the backrest portion 12), the flap portion 265 allows the auxiliary bag (control device) 262 connected to the storage bag body 261 to be positioned on one side in the left-right direction of the seat portion 11. The flap portion 265 also has an insertion portion 265a through which a cable 27 connecting the vibration device 24 and the control device 25 can be inserted, and the insertion portion 265a is provided to communicate with the interior of the storage bag body 261 and the auxiliary bag 263, respectively. By routing the cable 27 between the main storage bag body 261 and the auxiliary bag 263 through the insertion portion 265a of the flap portion 265, the cable 27 is prevented from being exposed to the outside.

[0041] As shown in Figure 4, the pair of bands 266, 266 are provided on the back surface of the storage bag body 261 opposite to the seating surface, and secure the storage bag body 261 to the seating surface 11 of the chair 1 when the storage bag body 261 containing the cushion 21 is placed on the seating surface 11. Each of the pair of bands 266, 266 is formed from a strip-shaped elastic material, and by elastically deforming (stretching), it secures the storage bag body 261 in close contact with the seating surface 11.

[0042] Figure 5 is a block diagram of the control device 25 according to this embodiment. As shown in Figure 5, the control device 25 is composed of a computer having a communication unit 251, an arithmetic unit 252 such as a CPU, a storage unit 253 such as RAM, ROM, or hard disk, and other peripheral circuits (not shown).

[0043] The communication unit 251 is configured to wirelessly communicate with the user's mobile terminal and external devices via a communication network. For example, the communication unit 251 is configured to wirelessly communicate with the user's mobile terminal via short-range wireless communication such as Bluetooth®, and to wirelessly communicate with external devices such as personal computers and external servers that the user normally uses via public wireless communication networks such as the Internet network and mobile phone networks. Note that the communication network includes not only public wireless communication networks but also closed communication networks established for each designated management area, such as wireless LAN and Wi-Fi®.

[0044] The calculation unit 252 has a functional configuration comprising an information receiving unit 252a, a determination unit 252b, and an information output unit 252c. The information receiving unit 252a receives various information and various commands. For example, the information receiving unit 252a receives various information such as seating signals output from the first to third seating sensor pairs 22a to 22c, count information output from the timer 23, and user schedule information input to external devices, as well as various commands such as stop commands for the vibration device 24 input from external devices such as the user's mobile terminal or a personal computer used by the user.

[0045] The determination unit 252b determines whether the user is seated in chair 1 or has left the chair based on the seating signal received by the information receiving unit 252a. For example, when the determination unit 252b receives seating signals output from each of the first to third seating sensor pairs 22a to 22c, it determines that the user is seated in chair 1. Similarly, the determination unit 252b also determines that the user is seated in chair 1 when it receives seating signals output from the first and second seating sensor pairs 22a, 22b, or only the first seating sensor pair 22a.

[0046] On the other hand, the determination unit 252b determines that the user has left their seat or stood up if the information receiving unit 252a has not received a seating signal from each of the first to third seating sensor pairs 22a to 22c. For example, the determination unit 252b determines that the user has left their seat if it has not received (detected) a seating signal output from each of the first to third seating sensor pairs 22a to 22c for a certain period of time or longer (for example, 5 minutes or more). Also, the determination unit 252b determines that the user has temporarily stood up if the time for which it has not received a seating signal from each of the first to third seating sensor pairs 22a to 22c is less than a certain period of time (for example, less than 5 minutes).

[0047] When the information receiving unit 252a receives seating signals output from the first to third seating sensor pairs 22a to 22c, the information output unit 252c outputs a count start signal to the timer 23. If the determination unit 252b determines that a user is seated in chair 1, and the information receiving unit 252a has been continuously receiving seating signals for a predetermined time or longer (for example, 60 minutes or more), the information output unit 252c outputs a drive signal to the vibration device 24. For example, the information output unit 252c outputs a drive signal to the vibration device 24 for 3 minutes, and then outputs a count reset signal to the timer 23.

[0048] Furthermore, if the information receiving unit 252a has not received a seating signal from each of the first to third seating sensor pairs 22a to 22c, the information output unit 252c outputs a count stop signal to the timer 23. Subsequently, if the determination unit 252b determines that the user has left their seat, the information output unit 252c outputs a count reset signal to the timer 23. On the other hand, if the determination unit 252b determines that the user has stood up, the information output unit 252c outputs a count restart signal to the timer 23.

[0049] Furthermore, the information output unit 252c is configured to not output a drive signal to the vibration device 24 during any time period (for example, a meeting) that is restricted from driving the vibration device 24, regardless of the user's seating time, based on the user's schedule information input to an external device and received by the information receiving unit 252a.

[0050] Furthermore, when the information output unit 252c is outputting a drive signal to the vibration device 24, if the information receiving unit 252a receives a command to stop the vibration device 24 from the user's mobile terminal or personal computer used by the user, the information output unit 252c stops outputting the drive signal to the vibration device 24.

[0051] The memory unit 253 stores various programs and data executed by the calculation unit 252. For example, the memory unit 253 stores a program for determining whether a user is seated on the cushion unit 21 and a seating time warning program that drives the vibration device 24 based on the seating time.

[0052] Figure 6 is a flowchart of the seating time warning process executed by the calculation unit 252 of the control device 25. The process shown in the flowchart of Figure 6 starts when the user sits down in chair 1.

[0053] First, in step S1, the timer 23 starts counting the seating time. Next, in step S2, it is determined whether or not a seating signal is continuously being input to the information receiving unit 252a. If it is confirmed in step S2, in step S3, it is determined whether or not a predetermined time has elapsed since the user sat down in the chair 1. If it is not confirmed in step S3, this is repeated until the predetermined time has elapsed. On the other hand, if it is confirmed in step S3, in step S4, a drive signal is output to the vibration device 24 to drive the vibration device 24.

[0054] Next, in step S5, it is determined whether or not 3 minutes have elapsed since the vibration device 24 was started to vibrate. If this is not determined in step S5, in step S6, it is determined whether or not a stop command has been input from the user. If this is not determined in step S6, the process returns to step S5 and is repeated. On the other hand, if this is confirmed in step S6, the process proceeds to step S7. Similarly, if this is confirmed in step S5, the process proceeds to step S7, the output of the drive signal to the vibration device 24 is stopped, and in step S8, the timer 23 count is reset and the process ends.

[0055] Furthermore, if the above step S2 is rejected, in step S9 the timer 23 stops counting, and in step S10 the determination unit 252b determines whether the user has left their seat or stood up. If it is determined in step S10 that the user has stood up, in step S11 the timer 23 restarts counting, and the process returns to step S2 and repeats. On the other hand, if it is determined in step S10 that the user has left their seat, the process proceeds to step S8, the timer 23 count is reset, and the process ends.

[0056] The seating time warning process of the cushion device 2 according to this embodiment is summarized as follows. First, when a predetermined time has elapsed since the user sat down in the chair 1, the vibration device 24 is activated to warn the user that they have been seated for a long time (steps S2 to S4). After this, if the user inputs a command to stop the vibration device 24, the vibration device 24 is stopped (step S6). If no stop command is input, the operation of the vibration device 24 is stopped after a predetermined time (3 minutes in the above example) (step S7), the timer counter is reset (step S8), and the process ends.

[0057] Furthermore, if the user moves away from the seating area 11 of chair 1 during the counting of seating time, the timer 23 temporarily stops counting, and it is determined whether this is simply because the user has stood up or because they have left their seat. If it is determined that the user has left their seat, the timer 23 counter is reset and the process ends (steps S10, S8). If the user has simply stood up, the timer 23 counting is restarted (steps S10, S11).

[0058] This embodiment can provide the following effects and advantages. (1) The cushion device 2 comprises a cushion section 21 that supports the buttocks of a seated user, a vibration device 24 that provides vibration to the user seated on the cushion section 21, a control device 25 that drives the vibration device 24 based on the seating time of the user seated on the cushion section 21, and a storage bag 26 capable of storing the cushion section 21 and the vibration device 24. The storage bag 26 has a storage bag body 261 capable of storing the cushion section 21 and a handle section 262 provided to make the storage bag body 261 portable. The vibration device 24 is stored in the handle section 262 and provides vibration to the user seated on the cushion section 21 via the handle section 262 (Figures 1 and 2).

[0059] In this configuration, the vibration device 24 is housed in the handle portion 262, and vibrations are delivered to the user sitting on the cushion portion 21 via the handle portion 262. As a result, the vibration device 24 does not come into contact with the buttocks of the user sitting on the cushion portion 21, thus suppressing the feeling of a foreign object being present to the user. In particular, when the cushion device 2 is attached to the chair 1, if the handle portion 262 is positioned in the gap between the seat portion 11 and the backrest portion 12 of the chair 1, the feeling of a foreign object being present to the user can be further reduced, and vibrations can be delivered near the user's buttocks (back side).

[0060] (2) The storage bag 26 further includes an auxiliary bag 263 capable of storing the control device 25, and the auxiliary bag 263 is provided connected to the storage bag body 261 (Figures 1 and 2). As a result, the control device 25 that controls the vibration device 24 is stored in an auxiliary bag 263 that is separate from the storage bag body 261 that stores the cushion section 21, so that the control device 25 does not come into direct or indirect contact with the buttocks of the user sitting on the cushion section 21, and the cushion device 2 does not give the user a feeling of foreign body sensation. In addition, since the auxiliary bag 263 that stores the control device 25 is provided connected to the storage bag body 261, the cushion device 2 can be carried as a single unit.

[0061] (3) The auxiliary bag 263 is connected to the storage bag body 261 via a foldable flap portion 265 (Figures 1 and 2). This allows the control device 25 to be positioned hanging from the cushion portion 21 to the side of the chair 1 via the flap portion 265 when the cushion portion 21 is placed on the chair 1 (Figure 4), thus making the cushion device 2 more compact when in use. In addition, by positioning the control device 25 facing the cushion portion 21 via the flap portion 265, the cushion device 2 can be made more compact for easy transport.

[0062] (4) The control device 25 and the vibration device 24 are wired together via a cable 27, and the flap portion 265 has an insertion portion 265a through which the cable 27 can be inserted (Figure 2). As a result, the control device 25 and the vibration device 24 are wired together using the cable 27 inserted inside the flap portion 265, so the cable 27 is not exposed to the outside, which improves the portability and usability of the cushioning device 2.

[0063] (5) The auxiliary bag 263, which faces the storage bag body 261 via the flap portion 265, is further equipped with a hook-and-loop fastener 264 for fixing it to the storage bag body 261 (Figure 4). By fixing the storage bag body 261 and the auxiliary bag 263, that is, the cushion portion 21 and the control device 25, facing each other, the cushion device 2 can be made smaller and its portability can be improved.

[0064] (6) The control device 25 stops the operation of the vibration device 24 regardless of the user's seating time, based on a pre-set user schedule (Figure 2). This allows the operation of the vibration device 24 to be limited in advance in environments where it is not desired to operate, such as during meetings. For example, since the limited time is set in advance based on the schedule, even if the user forgets to set the limited time, it is possible to prevent the vibration device 24 from operating in environments where it is not desired to operate.

[0065] (7) The control device 25 further comprises a first to third seating sensor pair 22a to 22c for detecting when a user sits on the cushion 21, and a timer 23 for counting the seating time. The control device 25 drives the vibration device 24 when the first to third seating sensor pair 22a to 22c detects that the user has been seated for a predetermined time or longer. If the seating state is not detected for a certain period of time or longer during the predetermined time count, the timer 23 resets the predetermined time count. If the time during which the seating state is not detected is less than a certain period of time, the timer continues to count the predetermined time (Figures 5 and 6). This excludes, for example, when the user readjusts their position or temporarily stands up from the predetermined time count, so that the actual seating time can be counted.

[0066] The above embodiment can be modified into various forms. For example, in the above embodiment, the vibration device 24 and the control device 25 are connected by a cable 27, but the vibration device 24 and the control device 25 may be connected wirelessly. In that case, the control device 25 may be installed on the cloud, or it may be installed on an external device such as a personal computer or server used by the user.

[0067] Furthermore, although the above embodiment described using a pair of first to third seating sensors 22a to 22c as the seating sensor 22, the arrangement position and number of seating sensors 22 are not limited thereto.

[0068] The above description is merely an example, and the present invention is not limited by the embodiments and modifications described above, as long as the features of the present invention are not impaired. It is also possible to arbitrarily combine one or more of the above embodiments and modifications, and to combine modifications with each other. [Explanation of symbols]
