Description
Technical Field
The invention relates to the technical field of ergonomic chairs, in particular to a spine health stretching chair.
Background
The spine, also known as vertebra, spine and spinal beam, is the general term for the accessible bones from top to bottom in the middle of the back of a human body, and comprises cervical vertebra, thoracic vertebra, lumbar vertebra, sacral vertebra and coccygeal vertebra. At present, the living states of many office workers are that the office workers sit for several hours in front of an office table in the daytime, occasionally get up and walk, the workers are easy to feel neck pain, and after getting home, the workers can lay down on a sofa or sit for watching television for several hours or play mobile phones and tablet computers; in addition, many children sit at the study table all the time and go over a desk for study in the daytime, and electronic products occupy most of the rest time. The bone, muscle, ligament and the like of the spine are affected due to factors such as lack of movement due to long-term sedentary, incorrect sitting posture, fatigue and relaxation of neck muscles caused by excessively lowering the head, more and more people show symptoms such as spinal aching pain and the like, and finally the spine is developed into reverse arch or upper cross syndrome, and the consequences are very serious.
For office workers or students, the sitting posture is not standard for a long time, so that the waist or the back is always in a suspended stress state, which is often the main reason of waist and back ache; the best solution is to correct the daily sitting posture of people, so various lumbar supports for correcting the sitting posture are also available on the market, and are usually arranged into an arc-shaped body which is convex in the middle of the spine shape of the human body and has elasticity to provide elastic support; however, the structure of the waist and back support is often single and simple, and only the waist of a user can be supported to play a waist supporting function, so that the waist and back support cannot be attached to the waist and back of the user during use, and when a human body actually sits on the chair, the sitting posture is dynamically changed, when the back of the user is twisted in the left and right directions, the waist and back support cannot be matched with the body of the user to be twisted to deform correspondingly, and one side of the waist or the back can be far away from the waist and back support, so that the support is lost. And then, some double-back waist pads gradually appear in the market, and the double-back waist pads adopt left and right separated back pads, so that the back part of the human body is more attached to the waist pad as far as possible, and the pressure born by the back is reduced. However, the two back cushions of the double-back waist cushion are completely separated, and the left back cushion and the right back cushion are different in shape, so that the die is independently opened and installed, and the processing cost is increased; in the use process, as the distance between the two back cushions is too large, the waist and the back of a user are inevitably separated, but the comfort level is general, and the design concept is contrary.
In addition, in addition to correcting sitting postures, for some user groups with lumbar spine strain or suffering from lumbar spine strain, spine stretching therapy is the most common and effective therapy, and by stretching the spine of a human body, the spine can be relaxed, so that pain can be effectively relieved; the existing seat basically does not have the function of stretching the spine of a human body, and at most, the waist of a user can be stretched slightly when the chair back is reclined through the waist rest on the seat; but this also only applies to the lower half of the human spine; for some users with sore upper back or neck, stretching and relaxing effects cannot be achieved.
Aiming at the problems, a sitting posture needs to be designed, and the sitting posture of a user can be corrected; and can stretch the spine of the human body when the chair is reclined.
