As shown in fig. 1 to 5, the present invention provides a sedentary prevention device, comprising:

the backrest comprises a backrest 1, wherein the backrest 1 comprises a backrest plate 11 and a cushion airbag 12 arranged on the backrest plate 11;

a seat 2, the seat 2 including a seat plate 21 and a seat airbag 22 disposed on the seat plate 21;

the sedentariness regulation and control system 3, sedentariness regulation and control system 3 includes controller 31, pressure sensor 32 and fills gassing device 33, and controller 31 is including the real-time collection module 311, pressure judgement module 312 and the position of sitting regulation module 313 that connect gradually, and pressure sensor 32 arranges in seat support 2 and/or back 1 and with real-time collection module 311 communication connection, fills gassing device 33 and leans on gasbag 12 and seat portion gasbag 22 intercommunication and with position of sitting regulation module 313 communication connection with the pad respectively.

In the invention, when a user sits in the anti-sedentary device, the pressure sensor 32 arranged on the seat 2 and/or the backrest 1 detects the pressure value of the user to the seat 2 and/or the backrest 1, the real-time acquisition module 311 acquires the pressure value, the pressure judgment module 312 judges whether the pressure value is greater than a preset value, and if yes, the sitting posture adjustment module 313 sends an inflation instruction to the inflation and deflation device 33 so that the inflation and deflation device 33 inflates the cushion-rest airbag 12 and the seat airbag 22. When the gas amount in the cushion airbag 12 and the seat airbag 22 reaches a predetermined amount, the inflation/deflation device 33 stops the inflation to maintain a predetermined gas pressure in the cushion airbag 12 and the seat airbag 22, so that the cushion airbag 12 and the seat airbag 22 maintain a comfortable softness. It should be noted that the pressure determination module 312 needs to use the pressure value of the user to the seat 2 and/or the backrest 1 when the user sits stably as the sedentary reference value. Thereafter, the pressure sensor 32 continuously detects the pressure value of the user to the seat 2 and/or the backrest 1, the real-time collecting module 311 continuously obtains the real-time pressure value, the pressure judging module 312 continuously judges the pressure difference between the real-time pressure value and the sedentary reference value, and if the pressure difference is relatively stable within a preset time period (for example, the pressure difference always belongs to a preset value interval), it indicates that the sedentary behavior of the user exists; if the pressure difference fluctuates greatly within the preset time period (for example, some pressure differences do not belong to the preset value interval), it indicates that the sedentary behavior does not exist for the user. When the pressure determining module 312 determines that the user has a sedentary behavior, the sitting posture adjusting module 313 controls the inflation/deflation device 33 to repeatedly inflate and deflate the seat airbag 22 and/or the cushion airbag 12, so that the user changes the sitting posture and reduces the pressure on the lumbar vertebra, and the hip and/or the waist and the back can be massaged and relaxed by repeatedly inflating and deflating the seat airbag 22 and/or the cushion airbag 12 without affecting the normal work of the user. Therefore, the sedentariness prevention device can avoid sedentariness of the user, adjust the sitting posture of the user, massage and relax the hip and/or the waist and the back, reduce the pressure on the lumbar vertebra and avoid influencing the normal work of the user.

As shown in fig. 4, in order to protect the cushion airbag 12 and improve the comfort of leaning, the backrest 1 further includes a soft cushion cover 13, and the soft cushion cover 13 covers the side of the cushion airbag 12 facing away from the backrest plate 11.
