The processor unit 120 stores the pressure value of the seating unit or the backrest air cell 30 measured by the sensor unit 110, the posture-related reference pressure value, a notification sound, or a notification message file. In this case, the micro SD can be inserted into the interface unit separately from the posture stabilizing unit, and the data recorded in the micro SD can be inserted into the interface unit, Can be read by the posture stabilizing device and used for posture pattern determination.

The sensing signal generating unit 130 generates a sensing signal for sensing the seating position of the user according to the sensing result of the air cells 30 sensed by the sensing unit 110 The sensing signal generator 130 may be configured as an electronic circuit which is a logical structure, not a physical structure, and may have various physical configurations.

The sensing signal generating unit 130 displays each air cell 30 as a contact point through a sensor unit 110 sensed from each air cell 30 and outputs each air cell 30 as a first point The second point, and the nth point, which are connected in a circuit so that the point of the displayed air cell 30 is displayed as a contact signal, and the sensor unit 110 of the contact point displays a sensed pressure value or a pressure change Thereby forming a posture detection signal for deriving a value as a signal.

The sensing signal generator 130 recognizes that there is a change in the pressure value when the first point and the second point contact the body part at each contact point, 120 and the posture detection signal is detected to be limited to the user's posture reference or posture reference range.

Accordingly, the posture correction range of the user is determined, and the air is changed in the air cell 30 to correct the posture.

The actuator module unit 170 includes a motor 172 for sucking in air and a fan for blowing air to the air cell 30. [ And a valve 171 corresponding to the number of air cells 30 associated with one motor 172 is connected to each of the air cells 30 so as to be connected to each other.

That is, the posture-related reference information includes information such as the user's basic information such as age, height, and weight, information on the main action in the sitting position, for example, whether the user is reading in a sitting position, handwriting, And whether or not to perform a medical treatment or the like.

The posture-related reference information can be used after the initial setting by adjusting the setting values in detail by the user if necessary.

The posture-related reference information may also include information about the notification to be provided to the user or the alarm, such as whether or not the smartphone notification message, the speaker guidance message, etc., the notification time, the notification interval, etc., . &Lt; / RTI >

The calibration determination unit 150 analyzes the posture information history data stored in the posture information storage unit 162 and detects a pressure pattern of the chair when the user is seated. The calibration determination unit 150 also determines which health condition should be suspected from the detected pressure pattern and matches the exercise content providing apparatus 161 for the correction posture and the correction stretching related to the determined disease.

At this time, the content for the correction exercise (posture or correction stretch) may be obtained from the separate content providing apparatus 161, but may be included in the posture information storage unit 162 in the form of a database. In the case where the contents of the correction movement are stored in the form of a database in the attitude information storage unit 162, the contents are stored in the form of data including a table including information on the symptom, the operation name, .

In addition, when acquiring the content from the separate exercise content providing device 161, the posture exercising apparatus 100 further includes a wireless communication unit for communicating with the external device.

The user interface unit 160 provides the user with suspected health abnormality information and the matched corrective posture and the corrective stretching operation through various types of data such as text, sound, or image through the display screen.

The posture stabilizing apparatus 100 is also capable of communicating with the interface unit 160 including the wireless communication unit so that the posture stabilizing apparatus 100 can measure the pressure in the plurality of pressure measuring air cells 30 detected for a predetermined detection time And related information from the interface unit 160.

Therefore, if the imbalance is continuously observed for a certain period of time on the left and right sides due to the pressure change of the air cell 30 when the user is seated on the seating portion 20, the scoliosis should be suspected to be more severe In the case of severe scoliosis, it is likely to be linked to pelvic imbalance. Therefore, according to the posture stabilizing apparatus 100 according to the present invention, when the degree of the spinal column alone is severe, not only the exercise contents matching the spinal column side symptoms but also the exercise contents according to the pelvis imbalance are provided.

The exercise content is forced to cause a pressure change of the air cell so that the user can actively exercise the exercise content or the user can select a specific part of the body part through the exercise activity of the exercise content and force the user to pressurize the air cell 30 And repeatedly applying a pressure change for a predetermined period of time.

If the sitting posture for a long period of time is continued for many years, it is likely to lead to a diagonal neck, turtle neck syndrome, etc. Therefore, before the serious abnormality is caused, It will be meaningful.

Here, anomalous symptoms will include symptoms that can be clearly labeled, such as scoliosis, vertebrae, vertebrae, turtle neck syndrome.

In addition, the actuator module unit 170 compares the posture-related reference pressure value with the pressure value at each point measured by the sensor unit 110, and determines whether the air is injected from the seating unit 20 or the back of the chair The air cell 30 is selected and determined to control at least one of an air injection rate, an air injection amount, an air injection holding time, a repetition number, and an air discharge order of a plurality of air cells.
