Chair capable of automatically rectifying sitting posture and application method thereof

Abstract

The invention discloses a chair capable of automatically rectifying sitting posture, and also discloses an application method of the chair capable of automatically rectifying sitting posture. Through at least two distance detection sensors arranged at a backrest, detection on inclined angle of a back of a human body is realized; through a pressure sensor, detection on motion states of legs of the human body is realized; through cooperation of the pressure sensor and the distance detection sensors, whether the human body is on the sitting surface of the chair is determined; through a lifting mechanism with lock-up capability, adjustment for the chair height is realized; through a rotation mechanism with lock-up capability and an inclined-angle sensor, adjustment for the horizontal angle of the sitting surface; and through cooperation with a minisize processor, automatic adjustment on the sitting-surface height and the horizontal angle is realized. Therefore, the chair helps to guarantee a human body to always have correct sitting posture and guarantee body health.

Description

technical field [0001] The invention relates to the technical field of furniture, and more specifically relates to a seat for automatically correcting sitting posture and a use method thereof. Background technique [0002] At present, myopia, hunchback, and spondylosis are the main diseases that plague children, teenagers, and office workers. The above-mentioned problems are mainly caused by bad sitting posture (legs shaking constantly, crossed legs, crossed feet), and keeping a fixed sitting posture for a long time. In response to the above problems, the seat has also undergone earth-shaking changes, and the functions and requirements for the seat are getting higher and higher, so seats suitable for different occasions have emerged as the times require. [0003] Seat surface lift: Seat surface lift refers to relying on the adjustment of the external joystick under the seat to perform pneumatic lift on the height of the seat surface. Through this function, the sitter can ad...

Problems solved by technology

[0009] Patent 201020678402 is an artificially adjustable lift seat; patent 201120207634 does not have a locking function, which cannot keep the human body in a good sitting posture with the legs correct, which will lead to various diseases over time

[0010] Because the seat is made of steel and wood, the structure of the table and stool legs is complicated. It is more troublesome for students to clean the classroom, and because the height cannot be adjusted at will, you need to borrow certain equipment to adjust the height, which leads to many schools. table

The air pressure rod of the air lift chair is filled with nitrogen gas. Generally, the gas purity is lower than 90%, which may cause safety hazards. If the air pressure rod is not tightly sealed, it will easily cause gas to burst out. In addition, the material of the external air pressure rod itself is also critical. If you use Unqualified materials may also cause explosions

[0011] The most important thing is that these seats can only artificially control the height or inclination angle of the seat unilaterally. There is no way to control both the height and the inclination, and there are certain limitations. For example, some can only be used in student classrooms, and some It is only suitable for the office use of office workers and does not have general significance
