Abstract

The utility model relates to a chair which can maintain the physiological curvature of a vertebral column, prevents and treats lumbago and cervical syndrome and conforms to a human engineering principle, and the chair is named after a vertebral column comforting chair. The utility model is composed of a chair seat, a chair seat and a chair back from top to bottom. The chair surface is shorter, and the upper surface of the chair surface is provided with a concave ischial tuberosity nest for preventing ischial tuberosity from sliding forwards. The chair back is columnar, and the front of the chair back is provided with a waist support, a chest support and a neck support from top to bottom and is respectively and movably connected with the chair back through a waist support handle, a chest support handle and a neck support handle. The connection mode can be U-shaped inserting rod mode or clamping tooth mode or screw thread mode, and a motor can be also used for regulating. A lumbar vertebra horizontal waist support which is positioned at the middle part at the front of the chair back can prevent a pelvis from tilting backwards and maintains the lumbar curvature of the vertebral column in the individuation mode. The horizontal chest support which is positioned at thoracic vertebra can maintain normal thoracic curve and prevents humpback. A C-shaped neck support which is positioned above the chair back is used for maintaining the physiological curvature of the cervical vertebra, a C-shaped support ring surrounds the top, when the position is regulated high, the effect of towing the cervical vertebra can be generated.

Description

The ridge chair relaxes

Technical field

The utility model relates to a kind of chair, and it meets ergonomics and biomechanical principle; Backbone is unfolded, and keep the physiological bending of backbone effectively, play the effect of preventing and treating pain in the back and cervical spondylopathy.

Background technology

Normal human's backbone has three physiological bendings at neck, chest, waist respectively.Cervical flexure, waist song are to lordosis, and chest Qu Xianghou is protruding.When human body was stood, the power that lumbar vertebrae is applied on the interverbebral disc was uniform (Fig. 1).When people are sitting on chair or the sofa, also can under the gravity effect, take a kind of posture with one's back bent naturally even without bending over one's desk working.This is because pelvis nature hypsokinesis and lumbar vertebrae cause (Fig. 2) to processus aboralis.Under this posture, since the center of gravity reach, the people that an individual weight is 70 kilograms, and under the lever principle effect, the pressure of its lumbar nucleus pulposus is up to 100 kilograms, much larger than the body weight of itself; With the passing of time certainly will cause the strain of annulus fibrosus disci intervertebralis and lumbosacral region ligament, bring out pain in the back; Even interverbebral disc is outstanding, pressuring neural root and cause skelagia.Same principle, the cervical vertebra strain can cause cervical spondylopathy.Its symptom comprises neck, shoulder, arm pain, and the legs and feet action is not nimble, Light-headedness, even fall in a swoon.Because in early days without any symptom, people are the harmfulness of conscious this posture not often, also thinks so very comfortable mistakenly.What it is about also not knowing up to suffering from a disease.The verified long-term seat of scientific research is the main reason that causes the backbone regression.No matter current seat tool is the hard chair, or couch all can not stop people to curl and the custom of sitting effectively.Though people's bolster head or the mat of a similar pillow is fixed on the chair back is rearward arranged at present,, also is difficult to correct this root problem of pelvis hypsokinesis because the relation of hardness and position is difficult to really keep the physiological bending of lumbar vertebrae.

Summary of the invention

Cyphotic drawback when more effectively overcoming seat, the utility model provides a kind of chair that can keep the backbone physiological bending.This chair by the adjustable support in multi-section position, makes backbone keep neck, chest, three sections physiological bendings of waist, thereby reaches the purpose (Fig. 3) of control neck-shoulder pain, lumbago and leg pain according to human anatomy and biomechanical principle.

The technical scheme that the utility model adopted is: be horizontally disposed with neck brace at the chair back in the middle part cervical vertebra, and the physiological bending degree difference required according to different people, it can be regulated front and back.According to the height difference of different people, it also can up-down adjustment.Neck brace is C shape on horizontal plane, the opening of C shape forward, size can be regulated.The thoracic vertebrae level is established the chest holder at the middle part, and the chest holder is front and back adjusting up and down also.The lumbar vertebrae level is established the waist holder at the middle part; The waist holder also can be up and down and the front and back adjusting.The utility model shortens seat, and at surface design one recess, is used for holding receiving ischial tuberosity.This can make the close chair back in position of ischial tuberosity, and can forwards not slide; This ischial tuberosity nest and waist holder acting in conjunction make the pelvis position of being kept upright, thereby prevent that its hypsokinesis from preventing waist section humpback.Chair back angle can be regulated, and when layback, can backbone be unfolded, and share a part of weight, reduces the interverbebral disc internal pressure.

The beneficial effects of the utility model are, when neck is attached on the neck brace, cervical vertebra are unfolded, and recover the physiological bending of cervical vertebra, improve neck blood fortune, thus the generation of pre-preventing cervical spondylosis; When the suitable constriction of neck brace C type opening, when simultaneously neck brace suitably being raise, can play draw to cervical vertebra by mandibular and occipital bone, this is one of the most effective therapy of treatment cervical spondylopathy.The chest holder is that chest section backbone provides support, and helps preventing bow-backed deformity.The waist holder to the acting in conjunction that stops of pelvis below ischial tuberosity, has prevented the pelvis hypsokinesis to the support of waist section backbone and ischium nest effectively, has kept before the physiology of lumbar vertebrae bent.Play the effect of prevention and treatment pain in the back.Short simultaneously seat can reduce the compressing to the thigh soft tissue, helps veins of lower extremity and refluxes.The adjustable angle of the chair back is for work and the conversion of resting state provide convenience.Help work when the chair back is upright, can bear the part body weight during chair back layback, and backbone is unfolded more.
