In order to further support the above technical solutions of the present application, it is now disclosed that the optimal design parameters and the parameter selection principle adopted in the design and manufacturing of the present application are as follows:

designing a seat: from the human engineering angle, when a person stands, the spine is in an S shape, the pressure in the intervertebral disc is relatively uniform, and the stress is relatively small; when a person sits down, the pelvis tilts backwards, and simultaneously the sacrum at the lower end of the back is driven to rotate, so that the intervertebral disc of the spine bears great pressure, the trunk structure of the human body cannot keep the original balance, and the body discomfort conditions such as lumbago and the like are caused. Therefore, in order to avoid the injury of the human body in the sitting posture, the pressure of all parts of the human body must be uniformly distributed when the human body sits on the chair.

Combining the above discussion, the basic principles of seat design: firstly, the design of the size of the seat should be different according to different users and purposes. Secondly, the specific size of the chair should be based on ergonomics. Thirdly, the cushion is designed to have a certain thickness, and the cushion is moderate in hardness, preferably semi-soft and slightly hard, so that the pressure on the waist of a person when the person sits can be dispersed to the ischial joint area, and the fatigue of the waist is relieved. Fourthly, the sitting surface of the chair has enough supporting function to the human body, and the height of the chair is proper, so that the thigh and the shank can be naturally relaxed when a person sits on the chair. Fifthly, the design of the backrest can fully support the trunk and relieve the pressure of the body weight on the buttocks.

The seat height of a typical chair is 400 to 440 mm. The seat height is one of the important factors influencing the sitting posture comfort degree, and if the height of the seat surface does not accord with the human body dimension, people feel tired easily. When the knee height is higher than the seat surface height, the body pressure of the body is mainly concentrated on the ischial node; when the knees and the seat surface of the chair are at the same height, the pressure of the ischial nodes can be dispersed to the buttocks, and a person can feel comfortable when sitting on the chair; when the knee height is lower than the seat surface height, two shanks of a person are suspended, the inner sides of the shanks are pressed, and the legs can swell after a long time. Therefore, the chair design should try to make the thigh and the shank at right angle, so that the sole is flat on the ground, the knee is not stressed, and the hip edge and the thigh obtain 'elastic support' on the chair seat. Secondly, the seat is wide: the width of the chair seat without the armrests is generally not less than 380 mm, and the width of the chair seat with the armrests is not less than 460 mm. Firstly, a certain movement space is ensured when a person sits on the seat, and the person can change different sitting postures to relieve the fatigue feeling of the body. Secondly, according to the thickness degree of people wearing clothes in different seasons, a proper clothes thickness space must be reserved in the design of the chair seat width. For a chair with armrests, if the seat surface is too narrow, the arms of the person must be retracted inwards; if the seat surface is too wide, the armrests will expand outward, and the hands of a person cannot be placed naturally, so that the size of the seat surface is larger than that of a seat without the armrests, and the seat surface is suitable. Thirdly, the backrest: the included angle between the seat surface and the base surface is more than 110 degrees. The backrest of the chair is designed to allow the torso of a person to be sufficiently relaxed, thereby reducing the strain on the waist and back and relieving the pressure on the buttocks caused by the body weight. In design, the greater the angle of inclination of the backrest, the greater the comfort of a person sitting thereon. When the included angle between the chair backrest and the seat surface is more than 110 degrees, the waist pressure of a person is obviously reduced. Therefore, the inclination angle of the chair backrest in the leisure place is generally large, so that people can conveniently have a rest and relax, and the inclination angle of the chair backrest is relatively small in the office space, so that people can easily get up when sitting on the chair backrest, and the chair is convenient for working and studying.

Thus, in one preferred embodiment of the present invention, the chair frame is designed to achieve an ergonomic chair size based on a frame having a length of 530mm, a width of about 320mm, and a height of about 500 mm.

The cushion is placed to its upper portion, and the box chamber wall that the cushion department top was placed to the skeleton is for 5 degrees slopes of vertical direction, satisfies the requirement of the comfort level of bowing back. The cushion material can be sponge foam and other cushions (other can be selected) meeting the light weight and firmness requirements.

The extension design of the two-layer seat: this may provide a rest space in a narrow environment since one layer of the seat provides only a cushion length of less than 320mm, but may result in insufficient comfort to some extent in a wide environment. Thus, an extension design of the second layer of seats is provided, which is generally hidden between the first layer of seats and the framework, and connected with the framework through a groove, and the extending length can be freely controlled. The two-layer seat has the total length of 465mm and the width of 230mm and can extend out by about 200mm at most. The leg-raising device can meet the requirement of completely relaxing the legs, and can also be derived to the function of providing the user with leg-raising function by the limit length.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
