Since 2005, we have served many customers who manufacture chairs 和 provided them with the core 皇冠搏彩中心网站倾斜机制.
They often discuss with us about the comfortable structure of chairs. 皇冠搏彩中心网站给他们的最重要的建议是 倾斜荷兰国际集团(ing)角 of the chair back adjusted by 倾斜 mechanism should not exceed 115 °. 这样的座位设置对使用者来说是最好的， 和用户 still can keep their healthy even they sit on an office chair for a long time.

Why should 倾斜 of the chair back adjusted by tilt mechanism not exceed 115 degrees?
让我来介绍一下 (施), a famous chair 设计er, told us how he 设计ed the comfortable chair.
And we can know from 他的 research that the seat back tilt adjusted by the chair tilt mechanism should be no more than 115 degrees, 哪个对用户的健康非常重要.
通过研究, it is found that the 设计 of most furniture puts comfort as the first priority, 健康是第二个.
只有设计 办公椅和床 必须 take health as the first appeal, 和 comfort the second. Because for the office workers, one-third of their time is spent sitting in an office chair. Sitting for a long time is depleted to the health of the human body.
床也是如此. 而对于其他种类的家具, 他们的申请时间不是很长, 和 people can constantly change postures on them to maintain comfort.
The natural state of the spine of every individual is different. 如何找到一个统一的标准?
Keeping the lumbar spine 和 pelvis straight is the natural state of the spine.
人的脊柱由颈椎组成, 胸椎, 腰椎, 骶骨和尾骨.
当坐在, 腰椎将这个力传递到骨盆, 和 then from the ischium under the hip bone to the seat surface. 在这个时候， backrest of the office chair forms a linkage relationship with the human lumbar spine 和 pelvis.
- 当人体是 坐直, 骨盆保持自然直立状态.
- 而人体是 倾斜的,骨盆 斜坡 同时.
T他的 is the connection relationship between the pelvis 和 the spine when the human body is active.
当身体活动时, verticality of the pelvis 和 the spine can make the pressure on the human intervertebral disc 和 the pressure distribution of each segment of the spine in the best state. It can reduce the probability of lumbar disc herniation due to prolonged sitting, 为了保持健康.
从视频中了解到, 图片, 和切片研究, it is preliminarily found that in various angles of sitting postures,
- 如果坐着的人的躯干向后倾斜 大约115° between the thighs, maximum verticality of the pelvis 和 the spine can be maintained.
- 如果倾斜是 超过115°，人体就会向后倾斜. And it tends to be lying in an unbalanced state, making thelumbar spine stressed suddenly.
After the establishment of the 115° st和ard, A-ONE 设计 team led by Mr. 史振宇进一步进行了研究 人和主持活动之间的关系.
The tilt movement of the human body is the joint movement of the knee bone, femur 和 scapula with the ankle bone as the fixed point. They depicted the linkage form of the ankle bone, knee bone, femur, 和 scapula in a ratio of 1:5.
在此基础上，他们获得了 基本尺寸范围 和 阀座表面的运动方式, 座椅靠垫和人体靠背的调节 在倾斜活动.
The parameters that should be the 设计 goals of the office chair
Study drawings of human sitting activities 和 chair activities range 和 methods (摘自《皇冠搏彩APP下载》)
- The distance between the seat surface 和 the ground should be no less than 100 mmwith the adjustment of 380-480 mm.
- The armrest should be no less than 70 mm away from the chair surfacewith the adjustment amount of 190-260 mm.
- The backrest has a downward adjustment of more than 70 mm.
- 当人体倾斜时, 皇冠搏彩中心网站表面向后移动55毫米, 皇冠搏彩中心网站表面倾斜6度, 皇冠搏彩中心网站的靠背是30度, 椅背扩张了115度.
Only the spine 和 pelvis in various sitting positions are consistent, 它能处于舒适健康的状态吗.
Research on Synchronous Inclination Activities (摘自《皇冠搏彩APP下载》)
The 设计 和 manufacture of our NT series tilt mechanism is based on the principle discovered by Mr. (Shi): The angle of 大约115° formed by the reclining of the sitting person’年代的躯干 和 他的 thigh is the maximum value that can maintain the verticality of the pelvis 和 the spine.
The starting 和 rear angle of 倾斜 mechanism should be between 85 degrees 和 115 degrees. 然后, the spine 和 the pelvis can be kept perpendicular to the pelvis as much as possible, 使座椅获得最大的舒适.

Research 和 development of a movement tilt mechanism with independent intellectual property rights
除了, 以上数据来自史振宇的研究团队, we can also know that in order to adapt to DIN5% of the population, seat back should be have an adjustment of more than 70 mm.
Another highlight of our NT series tilt mechanisms is that the height of the seat back can be adjusted independently. It is anther kind of user-friendly 设计 for seats of different heights.
If you are also 设计ing a new office or medical chair, please also consider “115°原则”. 这样的皇冠搏彩中心网站设计对使用者来说是最好的.
