Description

Office chair of the headrest, armrest waist, hip and leg possition changeability} with adjustable pillows, armrests, lumbar support, calves and hips

The chair relates to a chair that allows a user to conveniently work for a long time by making a chair with various functions added to the office chair so that the chair can be immediately rested.

Conventionally, various types of office chairs have been manufactured and used, but their functions have been limited in part, and they have not satisfied the increasing needs of chair users.

In this regard, the present applicant has filed an office functional chair to design, manufacture and supply the product more conveniently.

Up to now, the office chair has been used as if it fits the human body in the shape of a chair uncomfortably because it cannot move according to the user's body shape and head height preference even though the first pillow is attached.

Secondly, the back of the chair is made of flat, so it is necessary to have a S-shaped spine support at the waist according to the body type, so that a back cushion is often used on the waist.

This may or may not be necessary depending on the user's intention, but if you sit at your desk and work on a computer or paperwork, you need a backrest, and you don't need it when you want to rest in a chair. to be.

Thirdly, in the case of armrests, there are many chairs with various armrests, but because of the installation structure, they are attached to the buttocks and restrain the user's knees.

It is also much more efficient that the armrests are only needed when you are at rest or resting and not when you are teasing or working.

Fourth, in the case of an office chair, when you want to rest your back, you can't become a form of backrest because the center of the human body is pushed backwards.

However, car chairs, barber chairs, and sofa chairs are heavy enough to not move, but they cannot be used as light office chairs that need to be moved.

Therefore, office chairs have been used only for office purposes until now, and are not suitable for relaxation.

The task of this paper is to pursue a more efficient and convenient chair by making the office swivel chair as ergonomically as possible.

Therefore, the reality that needs to fit the user's human body in accordance with the shape of the chair is intended to be produced as the form of the human body.
