Description

A functional chair for the elderly based on ergonomics

technical field

The invention relates to a functional chair based on ergonomics, in particular to an ergonomic functional chair for the elderly which is suitable for most people and especially for the elderly.

Background technique

In daily life, seats with different functions are born according to the different needs of different groups of people, and seats of different designs are also required according to different age groups. For infants and young children, seats with strong protection are needed, and for children at different stages School students need learning seats of different heights and materials. For office workers who sit and work for a long time, they need seats with soft cushions and suitable backrests. For middle-aged and elderly people, they need to be easy to move and protect the spine. At the same time, in order to relieve fatigue and relax muscles and bones after work and study, people often use massage chairs to massage, smooth blood circulation, improve back pain and prevent diseases, improve sleep quality, and relieve body fatigue. Improve posture and exercise a healthy body, or add corresponding auxiliary functions to ordinary seats.

Common massage function chairs have many functions. Generally, a walking massage stick is used to massage the whole body of the human body, but its range of motion is large, which is more suitable for young people, but it does not meet their physical fitness for the elderly. To solve this problem The problem is that some inventors have designed massage chairs with low massage intensity in line with the physique of the elderly, but the existing functional massage chairs for the elderly still have the defects of inconvenient movement of the upper and lower seats and incomplete adjustment functions, which lead to the inability to completely improve when the elderly use it. Physical fitness. Therefore, in order to achieve the health of the elderly, improve their physical fitness, improve back pain and prevent diseases, it is necessary to provide them with multi-functional seats that are easy to move.
