Abstract

The utility model provides a student chair. The student chair comprises a chair seat (6), chair legs (8, 9) and a chair back (1), as well as a rectification structure, wherein the rectification structure is formed by mounting a chest support (2) on the chair back via a rigid chest support rod (3), the chest support rod comprises a telescopic rod in the front-and-back direction and a curved rod with a downward front end, the rear end of the telescopic rod is in rotating connection with the chair back via a horizontal shaft, and the lower end of the curved rod is connected with the chest support. According to the student chair disclosed by the utility model, the rectification structure uses the rigid chest support rod with a front-and-back telescopic structure for mounting the chest support onto the chair back; and compared with a rectification belt in the prior art, the chest support is arranged downwards from the shoulders, and the reasonable distance between the chest support and the chest during a correct sitting posture can be kept by regulating the telescopic rod, so that a sitter can keep the correct sitting posture without forward tilting, further the sufficient sight distance can be kept and the development of physique and skeleton can be prevent from being affected by arching of the back.

Description

The student uses chair

Technical field

The utility model relates to a kind of student and use chair.

Background technology

The student has certain influence to student's sitting posture and behavior in use with chair; Because student's most of the time all is sitting in the student with learning on the chair; If do not take correct sitting posture or abnormal activity; Not only can damage seat, also can make the student form bad habit, and further cause student's skeleton development undesired.Have many is student's seat generation of purpose with the rectifying sitting posture of student for this reason; " disclose orthopedic chair; it mainly comprises chair and fixed band; the said chair upper left corner is provided with a viscous box, the said chair lower right corner is provided with the fixedly fixed bin of fixed band, and said viscous box is equipped with and can makes turn forward 45 ° to 50 ° fixed band of people like Chinese invention patent application " orthopedic chair " (publication number CN101467820) this application." but this type student seat exists rectification indifferent.

Summary of the invention

To above-mentioned deficiency, the utility model is exactly that a kind of student's seat that stronger sitting posture and behaviour modification ability are arranged will be provided.

The utility model provides the student seat; Seat, chair pin, the chair back are arranged; Correct structure in addition, said rectification structure is that the chest holder is installed on the chair back through rigidity chest pressure pin, and the chest pressure pin is made up of the expansion link and the downward knee of front end of fore-and-aft direction; The expansion link rear end and the chair back are rotationally connected as trunnion axis, and the knee lower end connects the chest holder.

The utility model provides the student seat; Wherein correcting structure has used chest pressure pin rigidity, that elastic structure is arranged that the chest holder is installed to the chair back; With the orthopaedic belt of prior art relatively, the chest holder is provided with downwards from shoulder, and can keep rational distance by the chest when regulating expansion link and make the chest holder with correct sitting posture; So that the seat person keeps correct sitting posture, can not lean forward and keep enough sighting distances and can not influence the build skeleton development by hogback.

Be connected by height adjustment mechanism between the said chair back and the seat, use with the student who adapts to different heights through the height of regulating the chair back.

The utility model provides the student seat, also has a head rest, and head rest is installed on the chair back through the head rest bar, provides a head to rely on to the student, to prevent the layback of student's head, not only limits behavior but also help health; Said head rest bar is connected with the chair back through height adjustment mechanism, uses with the student who adapts to different heights through the height of regulating head rest.

Said chest pressure pin is installed on the chair back through the cross bar that is installed on the head rest bar, concerns to be fit to relation relatively more fixing phenomenon in position between the human body cephalothorax with the fixing position between chest holder and the head rest.

The part that said chair pin contacts with ground is the cross bar of fore-and-aft direction, cross bar length before and after the seat beyond plumb line, to increase with the chair needed moment that rocks back and forth; Preferably seat front side downwarping with the difficulty that further increase chair leans forward, makes the student keep good behavioural habits.Simultaneously, under the situation that chair can not rock back and forth, the collision noise on chair pin and ground just can not produce.Compare with the scheme of prior art Chinese invention patent application " anti-noise leg of stool and chair " (publication number CN101803836) public use spring, the utility model more simply and also has the function of correcting students ' behavior.
