Therefore, the sitting posture correcting device and the sitting posture correcting method realize the sitting posture correcting function for the user.

Referring to fig. 6, in use, a user sits on the correcting chair and corrects his sitting posture by activating the power supply, and the correcting chair stores usage data by detecting whether the storage module 9 is storing usage data, and two conditions are adopted at this time:

case one: when the last use data is detected, the control module 5 can call the data of the sensor module 7 in the storage module 9, the air charging and discharging module 6 adjusts the air bag module 10 through the data, and the air bag module 10 completes the adjustment of the chair back 4 through the air charging and discharging of the air bag.

And a second case: the last use data (namely the first use) is not detected, the operation control panel 13 adjusts the air bag module 10 through the inflation and deflation module 6, and the chair back 4 is correspondingly adjusted until the operation is finished;

at the end of use, the system stores the last sensor module 7 data in the memory module 9 and recalls it for the next use.

During use, since the airbag module 10 is not a completely closed whole, there is some leakage of gas, the sensor module 7 periodically detects and timely inflates to ensure that the position of the seat back 4 is not affected; when the sensor module 7 does not detect that a person is in use, the correcting chair can be switched into a standby state and does not work any more so as to ensure that electric quantity is not wasted.

Therefore, the invention realizes the functions of memorizing and automatically adjusting the use data of the correcting chair.

The implementation principle of the embodiment is as follows: the invention discloses a memory waist support chair for correcting sitting postures, which is characterized in that an air bag assembly 10 is arranged between a chair back 4 and a bracket 2, and the air bag assembly 10 is inflated or deflated through an inflation and deflation module 6 to enable the chair back 4 to rotate forwards and backwards, so that the function of adjusting the chair back of the waist support chair is realized. The waist support chair also has a memory function, after the angle of the chair back 4 is adjusted each time, the sensor module 7 can collect and transmit air pressure data in the air bag module 10 to the storage module 9, when the waist support chair is used next time, the control module 5 calls the data in the storage module 9 and sends a signal instruction to the inflation and deflation module 6, the inflation and deflation module 6 adjusts the air bag module 10 through the data, and the air bag module 10 completes the adjustment of the chair back 4 through the inflation and deflation of the air bag. The product design accords with ergonomics, can adapt to back actions of users, can effectively support and correct the users, and has great economic popularization value.

The embodiments of the present invention are all preferred embodiments of the present invention, and are not intended to limit the scope of the present invention in this way, therefore: all equivalent changes in structure, shape and principle of the invention should be covered in the scope of protection of the invention.
