Abstract

The utility model provides a cervical vertebra protecting chair and a cervical vertebra protecting bracket, which are a novel chair and a device that can protect the cervical vertebra and can keep the seating posture. The structure of the traditional chair back is changed, a lumbar vertebra part, a dorsal vertebra part, and a cervical vertebra part respectively contact the human body, and the contact parts can be adjusted back and forth according to the condition of each person, the key point is as follows: the lumbar vertebra part is provided with a backrest which can be adjusted back and forth. The cervical vertebra protecting bracket device comprises a bracket board 1, a sleeve ring 2, a connecting rod 3, a rotating shaft 4, a fixing support 5, and the like. The bracket board adopts an injection molding, the front side thereof is similar to the shapes of the mandibula and the afterbrain part of the human body, and the rear side thereof is connected with a connecting rod through a hinge and the sleeve ring, so that the bracket board can freely rotate and can better contact the skin, the front position and the rear position of the bracket board can be adjusted through the sleeve ring, and the connecting rod can be adjusted up and down, the connecting rod is connected with the rotating shaft through a pin and the rotating shaft is connected with the fixing support so as to ensure that the bracket board can flexibly rotate along with the head of the user, and the whole device is fixed on the chair back through a base.

Description

Cervical vertebra protection chair, cervical vertebra protection carriage

Affiliated technical field

The utility model relates to a kind of cervical vertebra protection chair, cervical vertebra protection carriage, can play the protection cervical vertebra, keeps a kind of novel chair and the device of sitting posture.

Background technology

At present, the all high only shoulder of the backrest of known office, study seat, do not contact with cervical vertebra,, cause sitting posture to change owing to keep sitting posture very easily to cause fatigue for a long time, a lot of people also get used to hunchback, stoop when being seated, thereby form various bad sitting postures, it is long-time to anteflexion tired state that cervical vertebra is in, and muscle group is in spasticity behind the neck, run counter to normal cervical vertebrae physiological curve, also just be easy to suffer from cervical spondylopathy.From " geographical position " of cervical vertebra, not only will on the take the lead weight of cranium, also connect less thoracic vertebrae of activity and lumbar vertebrae down, should bear a heavy burden, movable flexibly again, in the course of time, just cause morbidity because of excessive fatigue easily.Because neck is in a prone posture for a long time, have influence on local blood circulation, musculi colli is strained, time one length will cause cervical spondylopathy.The present invention changes traditional office, a kind of utility model chair of learning block chair back shape, increases cervical vertebra protection bracket system in addition and play the purpose that keeps sitting posture protection cervical vertebra on the seat of original office, study.Cervical vertebra protection bracket system is not suitable for the installation of high back chair.

Summary of the invention

For all high only shoulder of backrest that overcomes tradition office, study seat; the problem that does not contact with cervical vertebra; the utility model provides a kind of chair; the outstanding characteristics that embody the human body sitting posture formula; on the basis of traditional Chinese chair, divide lumbar vertebrae, vertebra, three positions of cervical vertebra to contact, play the effect of the normal lumbar vertebrae of protection, vertebra, cervical vertebrae physiological curve with human body.Or on the basis that does not change present use chair, add cervical vertebra protection bracket system, because normal person's cervical vertebra has a physiological bending degree, best study or work posture are that neck is kept upright, and lean forward slightly, do not reverse, tilt.Its principle is that to utilize cervical vertebra protection bracket system contact with people's mandibular position with the bilateral point gb 20 be that the strong point holds up head, thereby alleviates the pressure of cervical vertebra and the state that is kept upright, and plays the effect of protecting cervical vertebra.

The technical scheme that its technical problem that solves the utility model adopts is: one of its feature is exactly to change traditional back structure, divide lumbar vertebrae, back of the body vertebra, three positions of cervical vertebra to contact with human body, and can be according to everyone situation, the contact site is adjusted in front and back, key be the lumbar vertebrae position have one can before and after the backrest regulated, can carry out front and back adjusting according to the requirement of human body; Two of its feature is exactly to form cervical vertebra protection bracket system by carrier frame plate, the collar, connecting rod, turning cylinder, fixed support etc.Wherein carrier frame plate adopts moulding, contain mutually with the shape of human lower jawbone and hindbrain part the front, with the bilateral point gb 20 is that the strong point holds up head, the back is connected with connecting rod with hinge, the collar, carrier frame plate is freely rotated, better contact skin, and can adjust the front and back position of carrier frame plate by the collar, and connecting rod can be adjusted up and down, connecting rod is connected by bearing pin with turning cylinder, turning cylinder is connected with base, and to guarantee that carrier frame plate can rotate flexibly along with the head part, base is fixed on the chair back by fixed support with whole device.In order to use cervical vertebra protection bracket system separately to current chairs transformation, whole device is fixed on chair face behind by fixed head.

The beneficial effects of the utility model are, simple structure, and design is tending towards hommization, and purposes is wider, and practicality is stronger, promptly can be used for the crowd and the office space of working before computer for a long time, plays the effect of protection cervical vertebra, also can be used for school and change sitting posture of student etc.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the vertical section structural map of cervical vertebra protection chair, first embodiment of cervical vertebra protection carriage

Fig. 2 is the structural map of cervical vertebra protection chair, second embodiment of cervical vertebra protection carriage

1. carrier frame plates among Fig. 1 (containing hinge and extension bar), the 2. collar, 3. connecting rod, 4. turning cylinder, 5. fixed support, 6. back backrest, 7. screw thread fixed head, 8. adjustment dish shape nut, 9. waist backrest, 10. chair

The specific embodiment

Carrier frame plate 1 is by the engineering plastics injection mo(u)lding in Fig. 1, the point gb 20 of its front upper after with head part's ear is that strong point bottom natural torsion contains mutually with the mandibular rear shape, the back is linked to each other with extension bar by hinge, (guaranteeing that by hinge carrier frame plate moves up and down with head) links to each other with the collar 2 by extension bar; The collar 2 is a sub-assembly, and two rings are vertical to be connected, and a ring level links to each other with the carrier frame plate connecting rod, and another ring links to each other perpendicular to connecting rod 3, thereby realizes adjusting the adjustment that the collar 2 guarantees carrier frame plate upper-lower position and width; Connecting rod 3 is connected with turning cylinder 4, in two holes above the connecting rod insertion turning cylinder of bilateral, prevent to rotate and extract with the alignment pin location, the axle journal of turning cylinder 4 lower ends inserts in the axis hole of fixed support 5 upper ends, fix it with shaft end ring, turning cylinder 4 can be in the fixed support axis hole be rotated flexibly, guarantee that carrier frame plate 1 together rotates with person neck.

Waist backrest 9 cooperates with the screw thread fixed head 7 that is welded on the chair back plate back by the screw rod at its back in Fig. 1, adjusts the seat, front and back of backrest with screw thread, fixes and locatees with adjusting dish shape nut 8 then.
