Office Chair Different Sitting Position
Aug 04, 2017

Office Chair Different sitting position

More and more people pay attention to the health and office efficiency of the members of the office, the good office chair to correct the staff's stature, the use of sitting work, and with the progress of technology, sitting will become the main future of our workers Way of working. As a result, office furniture office seat design and associated sitting analysis are increasingly gaining the attention and research of ergonomic researchers and designers.

      1, the office chair of the study of different sitting, the human intervertebral disc pressure and muscle load is a contradiction between the body. When the straight waist, the body to maintain the "S" type, the spine to keep the body standing when the most natural posture, intervertebral disc pressure is small, but because of the seat "h" shape limitations, so that people's muscle load increases. When the bending waist, although the reduction of muscle load, but also increased the internal pressure of the disc, this sitting will naturally make people's spine bending, legs, waist, buttocks burden increased, sedentary produce back pain.

      2, the emergence of modern kneeling in 1977 by the Norwegian designer Peter. Aobu Wei Ke from the ergonomic point of view of the design of the "BALANS" series of chairs, breaking the human thousands of years of traditional sitting, the " Sitting and sitting "and" foot and sitting "sitting in one, began a modern kneeling seat of the river. Kneeling posture, the human body slightly forward, the spine closest to the natural state of the human spine standing, so as to effectively prevent the spine bending. And because the body weight evenly distributed in the buttocks, thighs and knees, blood circulation and nerve tissue is not too much pressure, contribute to the body's blood circulation and breathing improvement. However, kneeling seats in the variability is not satisfactory. The user working in the kneeling chair, always maintain a forward position, and it is difficult to change the sitting position for rest, prolonged use will also cause the user's muscle fatigue.

      3, ergonomic principle - sitting change After the study shows that: when we use the seat, due to physical and psychological characteristics, the body will produce a sense of comfort, with the increase in sitting duration, then the perception of people also occurred Change, and gradually produce fatigue perception. The human body through this subjective state of the judge and reaction, will automatically adjust the state of the sitting unconscious to reduce the body's fatigue. Simply put, people even sitting in a very comfortable office chair, after a period of time can cause muscle fatigue. Therefore, the seat design must be possible to make people often change their position and position in order to reduce muscle pressure.

      4, can change the sitting position of the new office chair through the study of sitting, office chair design can break through the traditional. After my research, and access to the national utility model patents, a new form of office chairs appeared - can change the sitting office chair. People sitting on it, you can easily change the three positions of the human body sitting: the use of ordinary office chairs, kneeling chair use state and the use of recliner state. The change of sitting position is conducive to minimize the office staff due to prolonged work caused by the waist pain, neck, back fatigue and other symptoms. This new type of office chair is particularly suitable for workers who work long hours before the computer.
