Multi-functional seat

Abstract

The invention provides a multi-functional seat belonging to the field of daily living goods, which solves the problem that the existing seat is difficult to be fit for different fat and thin users because the lateral wings on the backrest of the existing seat are fixed with the backrest to cause the space between two lateral wings to be relatively fixed. The multi-functional seat comprises a base, a seat board and the backrest, wherein the seat board can lift up and down; the backrest can rotate forwards or backwards and comprises a backrest framework and a back pad; two sides of the backrest are respectively provided with one lateral wing; each side wing comprises a strutting piece connecting with the backrest framework and a soft interlayer coated outside the strutting piece; the two strutting pieces are both vertically hinged on the backrest, the hinged part of the two strutting pieces is provided with an adjusting device capable of enabling the two strutting pieces to rotate simultaneously around respective hinged part along opposite directions and positioning the two strutting pieces. In the invention, the two lateral wings can rotate right and left simultaneously at opposite directions, so that the space at the opening of the two lateral wings can be enlarged or decreased, and the seat can be suitable for different fat and thin users to take, thus achieving the purpose of safe taking and having comfortable sensation.

Description

technical field [0001] The invention relates to a seat, in particular to a seat with multiple functions, belonging to the field of daily necessities. Background technique [0002] Seats are a must-have item for daily home life and office work, and they can be seen everywhere. A general seat includes a base, a seat plate located on the base, and a backrest connected to the seat plate. With the improvement of living standards, people have higher and higher requirements for the performance of the seat, so there are various types of seats. Functional seats, such as adding the function of rotating and lifting the seat plate relative to the base, setting a pillow on the top of the backrest, etc., to suit the needs of different users. [0003] Some seats are provided with side wings on both sides of the backrest respectively, and the upper body of the human body is wrapped by the side wings to prevent rollover. Especially for the seat used on the vehicle, if there is no side wing...

AI Technical Summary

Problems solved by technology

Especially for the seat used on the vehicle, if there is no side wing package, the driver and passengers are easily thrown out due to the inertial deflection to one side when making a sharp turn

However, the existing side wings are all fixed on the backrest, and the distance between the two side wings is relatively fixed. It is not easy to enter between the two side wings for a burly person, or the package is too tight, causing discomfort; but for a thin person For example, large gaps will be created when wrapping, and collisions will occur when making sharp turns

[0004] In addition, the existing seat is usually also provided with armrests on both sides of the backrest. When sitting on the seat, the armrests can be opened to rest your hands. The structure of the seat armrests currently used is relatively complicated, and the operability is relatively poor. During the limit process, it needs to be handled with care, and excessive force should not be used, which makes the operation troublesome.

[0005] In addition, the back of the existing seat is usually composed of a back frame made of metal material and a back pad covered on the surface of the back frame. The back pad is made of soft material to make the pillow comfortable, but the front side of the back pad It is a flat surface, which does not conform to the physiological convexity of the human body, so that the waist of the human body cannot rest on it, especially due to the fatigue caused by long-term sitting, the waist of the human body sags and causes lumbar spondylosis such as lumbar muscle strain , such as lumbar disc herniation, slippage, fission, degeneration, deformity, instability, lumbar bone hyperplasia and ligament hyperplasia, etc.
