Description

Double-sided seat

Technical Field

The utility model relates to a seat, especially a double-sided seat.

Background

According to investigation, the incidence rate of lumbar pain of sitting workers is increased year by year, and the lumbar pain, the soreness of waist bones, the lumbar disc herniation and the muscular soreness of buttocks and shoulders become common diseases of sitting office workers. If a worker keeps an improper sitting posture for a long time, the worker can cause unbalanced stress of muscles and abnormal back projection of the lumbar vertebra, although the projection is tiny, the worker deviates from the normal physiological bending of the lumbar vertebra and can cause uncomfortable symptoms such as abdominal soreness, back pain and the like for a long time.

The fundamental reason for this poor sitting posture is due to the limitations of our current chair "h" configuration. It makes the official have to lean down for a long time and bend over the desk work, and the week gesture of handling official business of singly bowing makes the neck be in relatively fixed stiff state, and neck muscle takes place the spasm, aggravates cervical vertebra harm, causes the emergence of cervical vertebra disease.

The study shows that the human sitting posture is a pair of spears. When a human body sits straight, the vertebra of the human body basically keeps an S-shaped state, namely the most natural posture when the human body stands, and the pressure of the intervertebral disc is small. However, due to the limitation of the h-shaped shape of the common chair, the muscle load of the human body is increased, and discomfort symptoms such as back muscle ache and the like can be caused after a long-term sitting posture of straightening the waist. When a human body bends down and sits, although the load of muscles at the back can be relieved, the balance of the body is facilitated, the internal pressure between the intervertebral discs of the spine is increased, the spine of the human body bends due to long-term bending down and sitting, the burden of legs, waist and buttocks is increased, the discomfort phenomenon can be caused after long-term sitting, and two most common clinical diseases can be caused when the human body bends down and sits; degenerative diseases of the spine and herniated discs.

Detailed Description

The present invention will be described in further detail with reference to the following examples, which are illustrative of the present invention and are not intended to limit the present invention.

Example 1:

as shown in fig. 1 to 3, the present embodiment is composed of a chair back 1, a chair stool 2 and a chair frame 3, wherein the chair frame 3 includes a first supporting portion 31, a second supporting portion 32 and a third supporting portion 33, which can be understood as chair legs, wherein the first supporting portion 31 is slightly higher than the second supporting portion 32, the third supporting portion 33 is significantly higher than the other supporting portions, and the upper ends of the first supporting portion 31 and the second supporting portion 32 are connected by an upper connecting portion 4. Referring to fig. 4, the upper connecting portion 4 is also used as a stool connecting portion, a stool connecting plate 41 is connected to the upper side of the upper connecting portion 4 through a screw, a guide post 42 is disposed on the stool connecting plate 41, and the guide post 42 is matched with a guide hole (not shown) disposed below the stool 2 to achieve insertion, extraction and installation of the stool 2.
