Assistant chair

Abstract

The invention discloses an assistant chair, comprising a chair frame, a seat plate and a lifting mechanism with a power device, wherein the seat plate comprises a front seat plate and a rear seat plate and is arranged on the upper end face of the chair frame, the front seat plate is in rotational connection with the rear seat plate, one end of the lifting mechanism is in rotational connection with the chair frame, and the other end of the lifting mechanism is in rotational connection with the front part of the front seat plate. The lifting mechanism is capable of controlling the lifting of the front and rear seat plates of the assistant chair, the front seat plate is in rotational connection with the rear seat plate, and when the lifting mechanism ascends, the front seat plate of the assistant chair is rotated from back to front by taking the front part of the front seat plate as central axis; and when the lifting mechanism descends, the front seat plate of the assistant chair is rotated from front to back by taking the front part of the front seat plate as central axis. The front seat plate clings to thighs so as to support body when a user rises and sits down, in this way, the body of the user is free from hanging in the air during rising, besides, body balance can be maintained without waist strength from the user because the chair seat provides vertical support.

Description

technical field [0001] The invention relates to the field of auxiliary equipment, in particular to an auxiliary chair. Background technique [0002] A chair is an indispensable device in people's life, especially for the old, weak, sick and disabled, it is very necessary to have a chair that reduces exertion. [0003] A general chair includes a chair frame, a seat board, and a backrest. When in use, in order to sit on a seat board whose height is different from that of a person's buttocks, the legs need to be bent, and the body is shifted backwards and downwards, which will cause the center of gravity to leave the support of the legs. In order to balance the deviation of the center of gravity, the human body will bend forward, the buttocks and thighs will hang in the air without force, until the buttocks touch the seat. In the same way, when standing up from a chair, there is also a stage where the hips and thighs are suspended for a long time. This suspension stage requir...

AI Technical Summary

Problems solved by technology

This suspension stage requires the waist and legs to support and balance the body. For the elderly or other people with weak waist and legs due to diseases, they either cannot do some movements, or they are prone to fall or lose their balance during the process, so they need the support of others.

[0004] At present, there are also some auxiliary chairs that use external power to tilt the seat forward at a certain angle, so that the user can get a forward and upward auxiliary power in the initial stage of getting up, but the angle of inclination of the seat is limited, otherwise it is easy for the user buttocks slide down to wrestle

The limitation of the angle makes the center of gravity rise and the forward range is very small, and the degree of assistance for getting up is very small. There is still a long period of hip and thigh hanging in the air, and the body cannot be supported.
