Description

Multipurpose chair

Technical Field

The invention belongs to the technical field of seats, and particularly relates to a multipurpose chair.

Background

White neck crowd accounts for than great among the social labor crowd at present, the state of this crowd's working day in the office generally uses the computer official working for sitting on the office chair, the noon period lies prone at the desk rest, but lie prone at the desk rest and take place the obstructed condition of blood circulation easily, thereby cause foot anesthesia or dizziness etc. reach the effect of rest, consequently, the folding bed that an office was used has appeared on the market, but the general space of office station is all comparatively narrow, the folding bed can occupy too much space when not using equally, consequently, it is not convenient enough.

Therefore, a chair for sitting and lying has also appeared in the market at present, for example, chinese patent CN108125434A discloses a chair, the chair back can be turned over relative to the seat plate, and can satisfy two postures of sitting and lying, so that one chair can be used as a seat in office, and can be used as a bed in rest; however, in the implementation process, it is found that when people sit on the chair for a long time to work, the buttocks, the lumbar vertebrae and the cervical vertebrae bear large pressure, a series of health problems can be caused, such as lumbar disc herniation, cervical vertebra ache, hemorrhoids and the like, and the chair on the current market is that the seat plate is always in a horizontal state, and only the angle of the chair back can be adjusted, so that the included angle between the chair back and the seat plate is adjusted, and thus people still sit on the seat plate in a bent manner, and the health problems caused by long-time sitting cannot be solved.

Disclosure of Invention

The invention aims to overcome at least one defect in the prior art, and provides a multifunctional chair which can be matched with various postures of sitting, lying and leaning of people, realize the conversion of office postures and rest postures at any time, and avoid the health problems of lumbar disc herniation and the like caused by long-time sitting and working of people.

In order to solve the technical problems, the invention adopts the technical scheme that:
