Chair size: backrest size

The size of the backrest is mainly related to the height from the bottom to the shoulder of the hip (which determines the backrest height) and the shoulder width (which determines the width of the backrest).
Chair seat inclination
Sitting face inclination: When a person is resting, the seated position is leaning backwards to support the lumbar spine. Therefore, most of the general seats are designed to tilt backward. The seat inclination is generally 3 to 5 degrees, and the opposite seat back is also tilted backward.
Chair size: seated deep
Sitting deep refers to the distance from the front edge to the back edge of the chair surface, and the depth of the sitting depth has great influence on the comfort of the human sitting posture. If the chair is sitting deeper than the horizontal length of the thigh, the backrest of the human body will have a large inclination, and the waist lacks a supporting point and is left floating, which intensifies the muscular activity of the waist and causes fatigue; meanwhile, the seat is too deep to make the knee There is a numb reaction and it is not conducive to standing. The horizontal length of the thighs in China's human sitting posture is average: 445mm for men and 425mm for women, and then ensuring that the front edge of the seat has a certain distance from the inside of the knee (about 60mm), so that the depth of sitting is generally between 380~420mm.

The width of shoulder should be based on the comfortable posture of the natural vertical arm.

Since the chair surface is often tilted backwards, the sitting height of the chair is usually the height of the seat as the sitting height of the chair. Appropriate seat height: The thigh should be kept horizontal with the calf vertical and feet flat on the ground.
Chair size: armrest height
According to the human body scale, the vertical distance from the upper surface of the armrest to the sitting surface is 200-250mm, and the front end of the armrest is slightly raised. The inclination of the armrest is generally 10-20 as the inclination of the sitting surface and the inclination of the basic backrest change. Degree, and the horizontal deviation of the handrail is ±10 degrees, which is generally consistent with the shape of the seat.
