Description

Wooden chair that conforms to human body sitting posture

technical field

The invention relates to a wooden chair, in particular to a wooden chair conforming to the sitting posture of a human body.

Background technique

Chairs are an important part of modern home life. A chair that fits the curve of the human body can not only provide a comfortable working and resting environment, but also benefit the health of the human body. At present, the materials that are widely used in the manufacture of chairs include wood, metal materials, plastics, and other natural materials and synthetic materials with certain strength. Wood is one of the most common and traditional materials used when making chairs. Because wood has the advantages of absorbing ultraviolet rays, reflecting infrared rays, moderate thermal conductivity, and regulating humidity in air, wooden chairs are still favored by people.

With the continuous improvement of modern home and office requirements, people not only pursue the appearance of chairs, but also pay more attention to the practical functions of chairs. Studies have shown that different chair shapes have different effects on the human body. For example, soft chairs tend to make people's brains slow, and the size and shape of the back of the chair directly affect the degree of muscle fatigue. Therefore, in the design of chairs, it should be based on the principles of ergonomics, and the chairs suitable for different functions such as office and leisure should be tested. At present, the design and manufacture of chairs mainly focus on appearance and material, ignoring the different functions of chairs.

Contents of the invention

The purpose of the present invention is to propose a kind of wooden chair which is not only beneficial to the comfort of the human body, but also beneficial to the health of the human body, which is not easy to produce muscle fatigue and conforms to the sitting posture of the human body.

The purpose of the present invention can be achieved through the following technical solutions:

A wooden chair that conforms to the sitting posture of the human body, including a base, a back support, the base and the back support are fit and connected as a whole, and three pillows with a width of 100 to 150 mm are arranged side by side on the upper surface of the base, and the distance between the pillows is 10 mm to 20 mm , the height of each seat pillow from the bottom surface of the base is 400 mm to 450 mm, the inclination angle of each seat pillow is 0° to 5°, the inclination angle of the back brace is 75° to 85°, and the upper and lower parts of the back brace are each equipped with a For back pillows, the width of the upper back pillow is 150 mm to 200 mm, the width of the lower back pillow is 100 mm to 150 mm, and the distance between the upper and lower back pillows is 200 mm to 300 mm.

The object of the present invention can also be further realized by the following technical measures:

The aforementioned wooden chair conforming to the sitting posture of the human body, wherein the thickness of the seat pillow is 40 mm to 60 mm.

The advantages of the present invention are: the wooden chair of the present invention is designed based on the principle of ergonomics and conforms to the sitting posture of the human body. The width is 100-150mm, the thickness is 40mm-60mm, the distance between the pillows is 10mm-20mm, and the pillow surface is 320mm-490mm, which conforms to the characteristics of human sitting posture and improves the comfort of the human body. ②The height of the pillow is designed to be 400 mm to 450 mm, so that the human body can get better comfort and is not prone to fatigue. The inclination angle β of the pillow surface is designed to be 0° to 5°, which can prevent the human buttocks from slipping out of the pillow surface . ③The back support of the wooden chair adopts the form of two upper and lower back pillows. The width of the upper back pillow is 150 mm to 200 mm, and the width of the lower back pillow is 100 mm to 150 mm, so that the back support of the wooden chair will not be supported for a long time. Supporting the curved part of the lumbar spine, the human lumbar spine is not prone to fatigue and soreness. In addition, the upper back pillow of the designed wooden chair is wider than the lower back pillow, which provides good support for the human neck. ④The inclination angle α of the back support of the wooden chair is designed to be 75°～85°. The back support adopts a trapezoidal cross-section form, which improves the structural strength of the back support. At the same time, a support pillow is added for placing items, which is convenient to use.

Detailed ways

The present invention is a wooden chair conforming to the sitting posture of the human body. It is designed based on the principle of ergonomics, and is mainly designed from the aspects of the width, spacing, and height of the seat pillow, the width, and spacing of the back pillow, so that the human body can get better Comfortable, not prone to fatigue. The width of the pillow surface directly affects the comfort of the human body. When the width of the pillow surface is too narrow, generally less than 250 mm, the human body not only feels stiff, but also feels squeezed on both sides of the body. When the width of the pillow surface is too wide, generally greater than 600 mm, the human body's buttocks will inevitably stretch outwards, stretching the latissimus dorsi and shoulder deltoids and other tendon tissues, which is prone to fatigue. Experimental research shows that when the width of the pillow is between 300 mm and 500 mm, the human body in the chair can get better comfort, and the gap between the pillows can also buffer the stretching fatigue of the muscles. Put three pillows on the pillow surface. The width of the pillow is 100-150mm, the thickness is 40mm-60mm, and the distance between the pillows is 10mm-20mm, which can meet the width requirements of the pillow surface and make the human body more comfortable. You can get better comfort and buffer the stretching fatigue of muscles.

If the height of the pillow is too high, the legs of the human body are suspended in the air. At this time, the muscles of the legs are under pressure, while the muscles of the thigh, calf and back are in a state of tension, and the human body is easily fatigued; When the height is lower than the knees or the calf is less than 90°, the body pressure is likely to be excessively concentrated, and the abdominal muscles are squeezed, which increases the load time of the back muscles of the human body. At this time, the waist and callus of the human body cannot be guaranteed The lower vertebrae are in a comfortable state, causing pain and discomfort, and are particularly prone to fatigue. Experimental research shows that when the height of the pillow is about 1/4 of the height of the human body, the human body can obtain better comfort and is less prone to fatigue. According to the sampling survey, the height of the general population is concentrated in the range of 1600 mm to 1750 mm, so the designed seat pillow height is 400 mm to 450 mm. In order to prevent the human buttocks from sliding out of the pillow surface, the inclination angle β of the pillow surface is designed to be 0°～5°.

Usually, the back support of the chair starts from the first or second lumbar vertebra of the human body and gradually increases upward to the shoulder blade or neck. However, through the analysis of human body structure, it is found that when the human body is in a sitting posture, the middle part of the lumbar spine on the back bends backwards. If the back support of the wooden chair supports the curved part of the lumbar spine for a long time, the human lumbar spine is prone to fatigue and soreness. Therefore, the form of two upper and lower back pillows is adopted. At the same time, in order to provide good support for the human neck, the upper back pillow of the wooden chair is designed to be wider than the lower back pillow. The width of the upper back pillow is 150 mm to 200 mm, and the width of the lower back pillow is 100 mm to 150 mm. The distance between the upper and lower back pillows is 200 mm to 300 mm.

When the inclination angle of the back support becomes smaller, the support point of the back of the human body gradually moves upward. Studies have shown that when the angle between the back support and the pillow surface is larger, the comfort of the human body is better, and it is more suitable for leisure. Taking into account the two different functions of work and leisure, the inclination angle α of the back support of the wooden chair is designed to be 75°-85°.
