Modes for Carrying Out the Invention

[0016] (First Embodiment) The first embodiment of this disclosure will be described below with reference to Figures 1 to 4.

[0017] Figure 1 shows a seating posture correction device 3 mounted on the seat 2 of an existing chair 1. As shown in Figure 1, the seating posture correction device 3 is portable. The seating posture correction device 3 is ready for use simply by placing it on the seat 2 of the chair 1.

[0018] The seating posture correction device 3 includes a seating section 4 and a plurality of balloons 5.

[0019] The seating portion 4 is the part on which the user can sit and is configured in a flat shape. Specifically, the seating portion 4 includes a base portion 4a which is a metal plate such as a stainless steel plate, and a cushion portion 4b which is a closed-cell structure such as urethane foam placed above the base portion 4a.

[0020] The multiple balloons 5 are a specific example of the bag. The multiple balloons 5 are positioned on the underside of the seating portion 4. The multiple balloons 5 are fixed to the underside of the seating portion 4. The multiple balloons 5 are fixed to the base portion 4a of the seating portion 4. The multiple balloons 5 include a right ischial balloon 5a, a left ischial balloon 5b, and a coccyx balloon 5c.

[0021] The right ischial balloon 5a is a balloon that corresponds to the right ischial tuberosity, which is the ischial tuberosity on the right leg side of a user seated on the seating area 4. The left ischial balloon 5b is a balloon that corresponds to the left ischial tuberosity, which is the ischial tuberosity on the left leg side of a user seated on the seating area 4. The coccyx balloon 5c is a balloon that corresponds to the coccyx of a user seated on the seating area 4.

[0022] Figure 2 shows a plan view of the pelvis of a user seated on the seating area 4. As shown in Figure 2, the right ischial balloon 5a is positioned directly below the ischial tuberosity on the right leg. The left ischial balloon 5b is positioned directly below the ischial tuberosity on the left leg. The coccyx balloon 5c is positioned directly below the coccyx.

[0023] Typically, the cushion portion 4b of the seating portion 4 has a recess formed therein to position the pelvis of the user seated on the seating portion 4 relative to the seating portion 4. The recess is typically formed to accommodate the user's buttocks, right thigh, and left thigh. Alternatively, the cushion portion 4b of the seating portion 4 may have lines drawn on it to indicate the position of the user's buttocks when seated on the seating portion 4. In this way, a desirable positional relationship between the seating portion 4 and the user's pelvis can be achieved.

[0024] Returning to Figure 1, each balloon 5 is formed in a hemispherical shape that is convex downwards. That is, each balloon 5 has a planar fixed surface 5P that faces the base portion 4a of the seat portion 4 in the vertical direction, and a hemispherical surface 5Q that is convex downwards. The hemispherical surface 5Q faces the seat surface 2 of the chair 1 in the vertical direction.

[0025] However, the shape of each balloon 5 is not limited to the hemispherical shape shown in Figure 1. Each balloon 5 can hold a gas, typically air, inside and its internal pressure can be adjusted by increasing or decreasing the amount of gas inside, regardless of its shape. Therefore, each balloon 5 may be spherical, columnar, ring-shaped, box-shaped, or other shapes, instead of the hemispherical shape exemplified in Figure 1. If a columnar shape is adopted for each balloon 5, as shown in Figure 8, each balloon 5 has a bellows (corrugated fold) on its outer circumference so that it expands and contracts in its longitudinal direction according to the internal pressure, and is positioned so that its longitudinal direction is vertical, i.e., perpendicular to the seating surface 2.

[0026] Figure 3 shows a functional block diagram of the seating posture correction device 3. The seating posture correction device 3 includes a compressor 10, a tank 11, a plurality of regulators 12, an acceleration sensor 13, and a control device 14. The compressor 10, tank 11, plurality of regulators 12, acceleration sensor 13, and control device 14 are typically housed in the seating section 4. However, instead, the compressor 10, tank 11, plurality of regulators 12, and control device 14 may be located outside the seating section 4.

[0027] The compressor 10 supplies compressed air to the tank 11. Multiple regulators 12 include a right ischial regulator 12a, a left ischial regulator 12b, and a coccyx regulator 12c.

[0028] The right ischial balloon 5a, the left ischial balloon 5b, and the coccyx balloon 5c are connected to the tank 11 via the right ischial regulator 12a, the left ischial regulator 12b, and the coccyx regulator 12c, respectively.

[0029] The acceleration sensor 13 is a specific example of a tilt measuring means for measuring the tilt of the seating area 4. The acceleration sensor 13 measures the pitch tilt angle and roll tilt angle of the seating area 4 and outputs angle signals indicating the pitch tilt angle and roll tilt angle to the control device 14.

[0030] As an example, the roll inclination angle is defined as follows: when the seating portion 4 is observed in a direction perpendicular to the frontal plane of a user seated on the seating portion 4, the front end of the base portion 4a of the seating portion 4 is horizontal when it is zero, the right leg side of the front end of the base portion 4a of the seating portion 4 is lower than the left leg side when it is positive, and the right leg side of the front end of the base portion 4a of the seating portion 4 is higher than the left leg side when it is negative.

[0031] As an example, the pitch inclination angle is defined as follows: when the seating portion 4 is observed in a direction perpendicular to the sagittal plane of a user seated on the seating portion 4, the side end of the base portion 4a of the seating portion 4 is horizontal, the positive angle is defined as when the knee side of the side end of the base portion 4a of the seating portion 4 is lower than the back side, and the negative angle is defined as when the knee side of the side end of the base portion 4a of the seating portion 4 is higher than the back side.

[0032] The control device 14 includes a CPU 14a (Central Processing Unit) as a central processing unit, read-write RAM 14b (Random Access Memory), and read-only ROM 14c (Read Only Memory). The CPU 14a reads and executes the control program stored in the ROM 14c, and the control program causes the CPU and other hardware to function as the internal pressure control unit 15.

[0033] The internal pressure control unit 15 individually controls the internal pressure of multiple balloons 5 based on the measurement results from the acceleration sensor 13 so that the tilt of the seating section 4 is within a predetermined range.

[0034] Here, the internal pressure control unit 15 is configured to individually control the internal pressure of the right ischial balloon 5a, the left ischial balloon 5b, and the coccyx balloon 5c. Specifically, the internal pressure control unit 15 increases or decreases the internal pressure of the right ischial balloon 5a by outputting a control signal to the right ischial regulator 12a. Similarly, the internal pressure control unit 15 increases or decreases the internal pressure of the left ischial balloon 5b by outputting a control signal to the left ischial regulator 12b. Similarly, the internal pressure control unit 15 increases or decreases the internal pressure of the coccyx balloon 5c by outputting a control signal to the coccyx regulator 12c.

[0035] Furthermore, the inclination of the seating portion 4 being within a predetermined range means that the pitch inclination angle of the seating portion 4 is within a first range, and the roll inclination angle of the seating portion 4 is within a second range.

[0036] The internal pressure control unit 15 adjusts the roll inclination angle by raising or lowering the right leg portion of the seating area 4 by increasing or decreasing the internal pressure of the right ischial balloon 5a. The internal pressure control unit 15 adjusts the roll inclination angle by raising or lowering the left leg portion of the seating area 4 by increasing or decreasing the internal pressure of the left ischial balloon 5b. The internal pressure control unit 15 adjusts the pitch inclination angle by raising or lowering the rear portion of the seating area 4 by increasing or decreasing the internal pressure of the coccyx balloon 5c. The internal pressure control unit 15 may also adjust the pitch inclination angle by raising or lowering the front portion of the seating area 4 by simultaneously increasing or decreasing the internal pressure of the right ischial balloon 5a and the left ischial balloon 5b.

[0037] Next, with reference to Figure 4, the control flow of the seating posture correction device 3 will be explained. First, the internal pressure control unit 15 receives angle signals from the acceleration sensor 13 indicating the roll inclination angle and pitch inclination angle (S100). Next, the internal pressure control unit 15 determines whether the inclination of the seating section 4 is within a predetermined range (S110). That is, the internal pressure control unit 15 determines whether the roll inclination angle and pitch inclination angle of the seating section 4 are appropriate (S110). If the inclination of the seating section 4 is within a predetermined range (S110: YES), the internal pressure control unit 15 returns to processing S100. On the other hand, if the inclination of the seating section 4 is not within a predetermined range (S110: NO), the internal pressure control unit 15 proceeds to processing S120. In step S120, the internal pressure control unit 15 individually controls the internal pressure of the multiple balloons 5 based on the measurement results from the acceleration sensor 13 so that the inclination of the seating portion 4 is within a predetermined range (S120), and then returns the process to S100.

[0038] For example, if the appropriate range for the roll inclination angle is set to -3 to +3 degrees, and the measured value of the roll inclination angle is +7 degrees, that is, if the right leg side of the front end of the base portion 4a of the seating portion 4 is too low compared to the left leg side, the internal pressure control unit 15 raises the right leg side of the base portion 4a of the seating portion 4 by increasing the internal pressure of the right ischial balloon 5a by a predetermined step. Alternatively, the internal pressure control unit 15 may lower the left leg side of the base portion 4a of the seating portion 4 by decreasing the internal pressure of the left ischial balloon 5b by a predetermined step.

[0039] Furthermore, for example, if the appropriate range for the pitch inclination angle is set to +5 to +10 degrees, and the measured value of the pitch inclination angle is -2 degrees, that is, when the knee side of the base portion 4a of the seating portion 4 is higher than the back side, the internal pressure control unit 15 raises the back side of the base portion 4a of the seating portion 4 by increasing the internal pressure of the coccyx balloon 5c by a predetermined step. Alternatively, the internal pressure control unit 15 may lower the knee side of the base portion 4a of the seating portion 4 by decreasing the internal pressure of the right ischial balloon 5a and the left ischial balloon 5b by a predetermined step.

[0040] In this way, the internal pressure control unit 15 repeatedly adjusts the tilt of the seating section 4, so that the tilt of the seating section 4 falls within a predetermined range. As a result, the left and right ischial tuberosities are aligned at the same height, and the pelvis is tilted slightly forward, that is, the user's sitting posture is corrected to an appropriate sitting posture. By maintaining an appropriate sitting posture, the user's fatigue after sitting for a long time can be alleviated.

[0041] The first embodiment of this disclosure has been described above. The first embodiment has the following features.

[0042] In other words, the seating posture correction device 3 that can be mounted on the seat surface 2 of chair 1 is A seating area 4 on which a user can sit, Multiple balloons 5 (bag-like structures) are positioned below the seating area 4, An acceleration sensor 13 (tilt measuring means) measures the tilt of the seating portion 4, An internal pressure control unit 15 (internal pressure control means) individually controls the internal pressure of multiple balloons 5 based on the measurement results from the acceleration sensor 13 so that the tilt of the seating portion 4 is within a predetermined range, Includes. With the above configuration, a device is provided that is applicable to an existing chair 1 and corrects the sitting posture.

[0043] Also, multiple balloons 5, The seating area 4 includes a right ischial balloon 5a (right ischial tube) corresponding to the right ischial tuberosity of the right leg of the user seated on the seating area, The left ischial balloon 5b (left ischial tuberosity) corresponds to the left ischial tuberosity of the left leg of the user seated on the seating area 4, The seating area 4 includes a coccyx balloon 5c (coccyx bag) that corresponds to the coccyx of the user seated there, Includes. With the above configuration, sitting posture can be effectively corrected with a small number of balloons (5).

[0044] Furthermore, the right ischial balloon 5a is positioned directly below the ischium on the right leg, the left ischial balloon 5b is positioned directly below the ischium on the left leg, and the right ischial balloon 5a is positioned directly below the coccyx. With the above configuration, sitting posture can be corrected more effectively with fewer balloons.

[0045] Furthermore, the seating posture correction device 3 includes an acceleration sensor 13 provided on the seating portion 4 as a means for measuring inclination. With the above configuration, a tilt measurement mechanism can be easily implemented.

[0046] (Second Embodiment) Next, a second embodiment of this disclosure will be described with reference to Figure 5. The following description will focus on the differences between this embodiment and the first embodiment, omitting any redundant explanations.

[0047] In the first embodiment described above, as shown in Figure 3, an acceleration sensor 13 is used as a tilt measuring means for measuring the tilt of the seating portion 4.

[0048] In contrast, in this embodiment, as shown in Figure 5, the pressure distribution sensor 20 and the tilt angle calculation unit 21 constitute a tilt measuring means for measuring the tilt of the seating portion 4.

[0049] The pressure distribution sensor 20 measures the pressure distribution on the upper surface of the seating portion 4 and outputs the pressure distribution data, which is the measurement result, to the control device 14.

[0050] The tilt angle calculation unit 21 calculates the tilt of the seating section 4 based on the pressure distribution data acquired from the pressure distribution sensor 20. Specifically, the tilt angle calculation unit 21 determines the centroid of the pressure distribution based on the pressure distribution data acquired from the pressure distribution sensor 20, and calculates the tilt of the seating section 4 based on the direction and amount of deviation of the centroid from the reference point. That is, the tilt angle calculation unit 21 calculates the roll tilt angle and pitch tilt angle of the seating section 4, respectively, based on the direction and amount of deviation of the centroid from the reference point. The relationship between the direction and amount of deviation of the centroid from the reference point and the roll tilt angle and pitch tilt angle of the seating section 4 may be determined logically or experimentally.

[0051] The second embodiment of this disclosure has been described above. The second embodiment has the following features.

[0052] In other words, the tilt measuring means includes a pressure distribution sensor 20 that measures the pressure distribution on the upper surface of the seating portion 4, and a tilt angle calculation unit 21 that calculates the tilt of the seating portion 4 based on the measurement results from the pressure distribution sensor 20. With the above configuration, a tilt measurement mechanism can be easily implemented.

[0053] (Third embodiment) The third embodiment will be described below with reference to Figures 6 and 7. The following description will focus on the differences between this embodiment and the first embodiment, omitting any redundant explanations.

[0054] Figure 6 shows a functional block diagram of the operation management system 100. As shown in Figure 6, the operation management system 100 includes a server 30 and a plurality of seating posture correction devices 3.

[0055] The server 30 is equipped with a CPU 30a (Central Processing Unit) as a central processing unit, read-write RAM 30b (Random Access Memory), and read-only ROM 30c (Read Only Memory). The CPU 30a reads and executes the control program stored in ROM 30c, which in turn causes the CPU and other hardware to function as the operation management unit 30d and the controller 30e. The seated posture correction device 3 is further equipped with a communication interface 30f. The operation management unit 30d and the controller 30e can communicate bidirectionally with the WAN 31 (Wide Area Network) via the communication interface 30f.

[0056] Each of the multiple seating posture correction devices 3 is capable of bidirectional communication with the server 30 via the WAN 31.

[0058] Each seating posture correction device 3 further includes a communication interface 40, an operation data transmission unit 41, and a control signal reception unit 42.

[0059] The operation data transmission unit 41 and control signal receiving unit 42 of each seating posture correction device 3 are capable of bidirectional communication with the WAN 31 via the communication interface 40.

[0060] The operation data transmission unit 41 of each seating posture correction device 3 generates operation data indicating the operating status of the seating posture correction device 3 and transmits the generated operation data to the server 30. The operating status can typically be defined by at least one of the control history of the internal pressure control unit 15, the operating time of the internal pressure control unit 15, and the operating time of the internal pressure control unit 15. The operation data transmission unit 41 generates and transmits the operation data at predetermined intervals. The predetermined interval is typically once a day.

[0061] Each seating posture correction device 3 has a control signal receiving unit 42 that receives control signals from the server 30. The internal pressure control unit 15 controls the internal pressure of the right ischial balloon 5a, etc., based on the control signals received by the control signal receiving unit 42. The control signals are signals for controlling the seating posture correction device 3. Typically, the control signals define the control of internal pressure by the internal pressure control unit 15. For example, the control signals define control to raise and lower the internal pressure of the right ischial balloon 5a at predetermined intervals. In this way, the server 30 can remotely and freely control the internal pressure of the right ischial balloon 5a.

[0062] The operation management unit 30d of the server 30 receives operation data from each seating posture correction device 3 and stores the received operation data in the RAM 30b.

[0063] The controller 30e of the server 30 generates a control signal for each seating posture correction device 3 based on the operational data collected by the operational management unit 30d, and transmits the generated control signal to the corresponding seating posture correction device 3. Typically, the controller 30e generates a control signal for each seating posture correction device 3 that defines a control to raise or lower the internal pressure of the right ischial balloon 5a at a predetermined interval when the operational status meets predetermined conditions, and transmits the generated control signal to the corresponding seating posture correction device 3.

[0064] Next, the control flow of server 30 will be explained with reference to Figure 7. Figure 7 shows the control flow of server 30.

[0065] S400: First, the operation management unit 30d of the server 30 receives operation data from each seating posture correction device 3.

[0066] S410: Next, the controller 30e of the server 30 generates a control signal and transmits the generated control signal to the corresponding seating posture correction device 3.

[0067] The third embodiment has been described above. The third embodiment has the following features.

[0068] The server 30 can communicate with multiple seating posture correction devices 3. The control method of the server 30 includes the steps of acquiring operational data of the seating posture correction devices 3 from the seating posture correction devices 3 (S400) and transmitting control signals to the seating posture correction devices 3 for control (S410).

[0069] In the above example, the program can be stored and supplied to the computer using various types of non-transitory computer-readable medium. Non-transitory computer-readable medium includes various types of tangible storage medium. Examples of non-transitory computer-readable medium include magnetic storage media (e.g., flexible disks, magnetic tapes, hard disk drives) and magneto-optical storage media (e.g., magneto-optical disks). Examples of non-transitory computer-readable medium further include CD-ROM (Read Only Memory), CD-R, CD-R / W, and semiconductor memory (e.g., mask ROM; examples of non-transitory computer-readable medium further include PROM (Programmable ROM), EPROM (Erasable PROM), flash ROM, and RAM (random access memory)). Alternatively, the program may be supplied to the computer by various types of transient computer-readable medium. Examples of transient computer-readable medium include electrical signals, optical signals, and electromagnetic waves. Temporary computer-readable media can supply programs to a computer via wired communication channels such as electric wires and optical fibers, or via wireless communication channels.
