a. Backrest design

此新型办公椅的靠背设计非常的新颖独特，它由两块独立的前独立靠背和底层靠背组成。前靠背造型接近人体肩胛骨，内置压缩弹簧与底层靠背连接，外部由记忆海绵包裹，在使用时可根据压力不同而独自转动，而且中间的空隙设计可减轻靠背对脊椎的压力。

The backrest design of this new office chair is very novel and unique. It is composed of two independent front backrest and bottom backrest. The shape of the front backrest is close to the shoulder blades of the human body, the built-in compression spring is connected with the bottom backrest, and the outside is wrapped by a memory sponge. When in use, it can rotate alone according to different pressures, and the gap design in the middle can reduce the pressure of the backrest on the spine.

靠背可根据不同的坐姿进行角度调节，由跪姿实验结果和躺姿靠背角度分析，靠背调节范围在80°～120°为宜。

The backrest can be adjusted according to different sitting posture. According to the experimental results of kneeling posture and the analysis of backrest angle of lying posture, the adjustment range of backrest should be 80 ° ~ 120 °.

b. 扶手设计

b. Handrail design

此办公椅的扶手可通过调节高度及横向伸缩以改变扶手的长短来适应不同年龄的使用者，使其更符合人机工程学原理。

The armrest of the office chair can adapt to users of different ages by adjusting the height and horizontal expansion to change the length of the armrest, so as to make it more in line with the principle of ergonomics.

c. 腿部支撑设计

c. Leg support design

此新型办公椅的腿部支撑的主要作用在于支撑腿部重量，增大人体重量的支撑面积，从而减小坐垫的压力，使人体压力分布过渡更趋均匀。腿部支撑杆由特制气杆组成，与座面和靠背的整体调节机构相连，可通过坐姿调节杆的变化而满足不同的坐姿需求：当普通办公坐姿使用时，支撑结构弹回，一点也不影响普通坐姿和座椅外观。

The main function of the leg support of the new office chair is to support the weight of the legs and increase the support area of the weight of the human body, so as to reduce the pressure of the cushion and make the transition of the pressure distribution of the human body more uniform. The leg support rod is composed of a special air rod, which is connected with the overall adjustment mechanism of the seat surface and backrest. It can meet different sitting posture needs through the change of the sitting posture adjustment rod: when the ordinary office sitting posture is used, the support structure bounces back, which does not affect the ordinary sitting posture and seat appearance at all.

当跪式坐姿使用时，支撑杆弹出，根据人体姿势调节距离和角度，达到效果；在躺姿使用时，腿部支撑弹出并旋转，充当脚撑作用，便于使用者休息。

When the kneeling sitting posture is used, the support rod pops up, and the distance and angle are adjusted according to the posture of the human body to achieve the effect; When used in the lying position, the leg support pops up and rotates to act as a foot support, which is convenient for the user to rest.

d. 座面设计

d. Seat surface design

此座椅的座面不仅在高度上可以调节，而且座面的角度可根据不同的坐姿而进行调节。根据跪姿实验结果和躺姿时座面角度分析，座面调节范围在15°～-20°为宜。

The seat surface of the seat can not only be adjusted in height, but also the angle of the seat surface can be adjusted according to different sitting positions. According to the experimental results of kneeling posture and the analysis of seat angle in lying posture, the seat adjustment range should be 15 ° ~ - 20 °.

e. 调节机构方便快捷

e. The adjusting mechanism is convenient and fast

此新型办公椅采用一杆多功能方式，由三种坐姿实验数据得出的使用角度，通过一杆使三种坐姿功能轻松转变，避免了由于功能太多而引起的调节杆过多，调节复杂等现象。

The new office chair adopts the one pole multi-function mode. According to the use angle obtained from the experimental data of three sitting positions, the functions of three sitting positions can be easily changed through one pole, so as to avoid the phenomena of too many adjusting rods and complex adjustment caused by too many functions.
