Description

M253274 V. Creative Instructions Π) [Technology

This creation is about a kind of seat with the seat facing the head of a person, the head of a stretcher, the head, and the waist, so as to obtain the comfort of the sitting position of the user's head. [Previous technology] The adjustable head of the chair and the waist pad structure are respectively equipped with the optimal support state of the waist and the waist by adjusting the telescopic cylinder body to adjust the pressure of the head. For those who are engaged in clerical work, because of prolonged sitting / documentation and processing of various documents, it is easy to cause blood path loss = acid back pain, even bone deformity, etc., so I choose the seat:

It is very important that a 'poorly designed seat' not only easily causes a bad sitting posture, but may also lead to the deterioration of the aforementioned symptoms. On the contrary, if the structure design of the seat can be ergonomic, it can improve the sitting comfort and be more moderate. Improvement: Bridge the above symptoms. ° From the perspective of the existing seat, although some industry players will emphasize that its seat design is fully ergonomic 'with appropriate support for its corresponding head and waist parts' to avoid poor sitting posture and improve long-term sitting fatigue Phenomenon, in fact, because the cushion structure of the head and waist of the seat is fixed design, it can obtain support for the user's head and waist, but because the user's body shape is different, his body head The shape of the curve of the waist area is also different. This fixed head and lumbar support structure may achieve the appropriate cushioning effect, but it is absolutely impossible to obtain the best support effect for each user's head and waist. For some users, it may indeed be able to achieve the sitting comfort, but for some users, it may not be possible to obtain a comfortable sitting posture, in other words

M253274 V. Creation Note (2), that this kind of "ergonomic" seat has not really achieved the best comfortable fall-selection effect in line with ergonomics, and there is still room for improvement. [New content] In view of the fact that the existing seat can not achieve the best comfort cushioning effect on the head and waist parts of users of different body shapes, the author's special work ^ research and improve, based on its related industries Years of experience and technology, and further developed the adjustable head and waist pad structure of this creation, that is, its main purpose is to provide a seat head and waist structure that can be adjusted according to different user body shapes, so as to obtain the human head, The best support type of the waist, can effectively improve the comfort of the sitting position. ~ Another purpose of this creation is to design the structure so that the adjustment of the head and waist pad can be achieved with the simplest structure and can be obtained when the user sits in the seat. Convenience. Another purpose of this creation is that under the adjustable functional structure of the seat head and lumbar cushion, the cushion body can be further designed to be pivotable or adjustable, which can be more suitable for the adjustment needs and grants of users of different sizes. Those who have a sitting position margin. In order to achieve the purpose of the previous disclosure, this creation is in the structural design, mainly in the seat corresponding to the head and waist of the body is provided with a recess, so that another head pad and waist pad assembly, and in the head, The back of the lumbar pad is respectively equipped with telescopic cylinders that are controlled by air pressure. The control parts of these telescopic cylinders are arranged on the side of the chair that the user can reach, so as to control the telescopic cylinders. Telescopic state, in order to adjust the head, waist pad and the user's head and waist to obtain the best support state, so as to improve the comfort of sitting position.
