Embodiment 1

[0029] Examples, see Figure 1 to Figure 6 and Figure 13 , the intelligent limiting device of the present embodiment is used for correcting sitting posture, and it comprises:

[0030] A restraint device, a drive system for driving the restraint device, and a control system for controlling the drive system. Wherein, the restraint device includes a position-limiting belt and a movable buckle 1 .

[0031] In the specific setting, the limit belt includes an upper limit belt 21 and a lower limit belt 22 connected by the movable buckle 1 , one end of the upper limit belt 21 is fixed on the movable buckle, and the other end is connected to the user. Such as Figure 6 As shown, the front of the spacer belt is provided with an upper spacer belt restraint female buckle 211 and an upper spacer belt restraint buckle sub-buckle 212. When the user uses it, the movable buckle is buckled on the chest to play a restraining role.

[0032] One end of the lower limit band 22 is connected to ...

Embodiment 2

[0041] The transmission and control parts are the same as those in the first embodiment. Compared with Embodiment 1, the difference is that, as Figure 7 to Figure 9 As shown, one end of the upper limit band (21) is fixedly connected to the lower end of the chair back, obliquely across the user's torso, and the other end is fixedly connected to the output rotating shaft (5).

Embodiment 3

[0043] Transmission, control part are identical with previous embodiment. Compared with Embodiment 1, the difference is that, as Figure 10 to Figure 12 As shown, one end of the upper limit band (21) wraps around the user's torso, passes through the armrest (81), and is fixedly connected to the fixing plate (6); the other end of the upper limit band (21) is fixedly connected to the output shaft (5) up. The upper limit belt (21) is located at the middle position of the front of the chair back, and is provided with an upper limit belt restraint buckle female buckle 211, and an upper limit belt restraint buckle buckle 212. During use, the movable buckle is buckled on the chest, play a restrictive role.

[0044] It should be noted that the parts not described in detail in the present invention belong to the well-known technologies in the art, or can be purchased directly from the market, and those skilled in the art can obtain them without creative work. There are extremely wide ...

Abstract

The invention discloses an intelligent limiting device for correcting a sitting posture. The intelligent limiting device comprises a restraining device, a driving system for driving the restraining device and a control system for controlling the driving system. A user can keep a correct sitting posture, the physiological curve of the waist is maintained, the actual utilization rate of a backrest is increased, the waist is supported for a long time, the stress of the waist is reduced, and the stress condition of the waist of the user is improved, so that the effect of protecting the waist is achieved.

Description

Technical field: [0001] The invention relates to an intelligent limit device for correcting sitting posture, which belongs to the technical field of waist support cushions. Background technique: [0002] The development of economy and society, the acceleration of people's life rhythm, these objective factors make people in modern society busy and tense at work. Studies have shown that people who are office workers and work in the office spend more and more time working at their desks in office chairs. According to the survey, more than 90% of people do not leave their office chairs for more than 1 hour in a row, and about 60% of the staff do not leave their office chairs for 2 hours in a row.
