Learning chair with self-adaptive driving and straightening framework

Abstract

The invention relates to the field of ergonomic chairs, and particularly relates to an intelligent ergonomic chair capable of correcting sitting postures. A chair frame comprises a chair back, a chair seat and a driving and straightening framework assembly, and the driving and straightening framework assembly comprises a bionic spine frame and a plurality of groups of multi-section shaping frames; a gravity pull-down assembly comprises two vertical pull rods capable of moving downwards along with descending of the chair seat, and a reversing assembly is provided with an output end capable of translating transversely along with longitudinal movement of the pull rods; and a multi-section shaping frame comprises a tough steel belt and a plurality of plate-shaped embracing arms, and a reset mechanism is arranged between every two adjacent plate-shaped embracing arms. When a student chair is used, the pressure of a human body on the chair seat can be converted into a cohesive force of the bionic spine frame, the cohesive state of the bionic spine frame can be adjusted according to different body types, different people have good comfort, the bionic spine frame can loosen the plate-shaped embracing arms along with the rising action of the people, and the student chair is high in flexibility and adaptability.

Description

technical field [0001] The invention relates to the field of ergonomic chairs, in particular to an intelligent ergonomic chair capable of correcting sitting posture. Background technique [0002] With the improvement of people's material life, all kinds of modern smart seats have been designed, and ergonomic chairs that meet the standards of human mechanics have become very popular, and the safety and comfort of ergonomic chairs have also become the focus of attention.

[0002] With the improvement of people's material life, all kinds of modern smart seats have been designed, and ergonomic chairs that meet the standards of human mechanics have become very popular, and the safety and comfort of ergonomic chairs have also become the focus of attention. The object that users pay attention to, so while ensuring the safety of the ergonomic chair, it is also necessary to properly modify the seat to improve the comfort, and it is best to correct the sitting posture, so the modification of the back of the ergonomic chair is also necessary. It has become very important. At present, in ergonomic chairs, the back of the chair adopts an integral bionic spine frame. Although the spine frame is made of soft materials, the adjustment range is limited, and the bionic spine cannot be greatly adjusted according to different body shapes. frame, low flexibility and small adaptability, so it is necessary to design a learning chair with a bionic spine frame that can adapt to different body shapes and can be adjusted
