A kind of health-care chair, in addition to the common seat necessary functions of in the market, the muscle and joint motion at the multiple positions of body can also be carried out on top, and strong waist, neck, upper limbs and lower limb, health care is played to lumbar vertebrae, cervical vertebra, shoulder etc. and slight illness of releiving acts on.Health-care chair profile approximation executive chair, possesses the basic function of chair, its exclusive mobilizable headrest, backrest, handrail and footstep mechanism.Headrest and backrest can swing back in stress, and resilience is in situ when stress reduces；Backrest is equipped with multigroup limberoller, and massage effect is played to back；The handrail of seat can be swung therewith in lasting stress, can temper arm and shoulder；Seat bottom is provided with footstep mechanism, usual folded concealed, such as deploys footstep mechanism, and both feet can be pedaled with lower limb with march.The people of crowd and inconvenient activity suitable for long-time sitting work are as work with chair and life chair.

Description

A kind of health-care chair

Technical field

A kind of health-care chair is the utility model is related to, in addition to the function with general seat, can also be carried out on top Limb activity, such as：Lumbar vertebrae, cervical vertebra, upper limbs and lower limb, play the health-care effect to joint parts such as lumbar vertebrae, cervical vertebra and shoulders.

Background technology

At present, the chair that in the market sale and people generally use, such as office chair, executive chair, couch, is all only It can meet that people are sitting in top, lean against the chair back, or the chair back was fallen certain angle, will lean back or semi-lying.When many long Between be sitting in worker on chair, waist can produce tired, next to that shoulder, neck and leg, long generally causes lumbar vertebrae and cervical vertebra Deformation and slight illness.

The content of the invention

In order to overcome the weak point of current chair, the utility model provides one kind except often using chair with the market Outside indispensable excellent function, can also movable waist, neck, upper limbs and lower limb on top health seat.

The backrest of seat can be replied forward, so when the people for being sitting in top firmly leans on backward with swing backward when loosening Back and forth with movable lumbar vertebrae and muscle of back；Backrest top headrest can people neck backward firmly be pressed against when swing backward, put Song Ze is restored forward, and cervical vertebra and musculi colli can be made to obtain activity and take exercise；The handrail of chair can be pulled firmly upwards, loosen Original position is then returned to afterwards, with movable arm and shoulder muscle；Retractable footstep mechanism is housed below chair, deploys pin above Pedal, both feet, which are firmly stepped on forward, to be pedaled, and pedal moves forward, and when leg is loosened, pedal is resiliently extremely in situ, and so on makes Lower limb and waist muscle obtain activity.

Technical scheme is used by the utility model solves its technical problem：

The bottom of backrest is hinged with seat board by one group of hinge arrangement for containing torsion spring, backrest when not by external force, Abutted in the presence of torsion spring with seat board and seat cushion, when exerting oneself pressured backward by people, using hinge as axle swing backward, stress reduces When, backrest resilience, is back to original position under the active force of torsion spring.The headrest cage plate of fixed headrest passes through the hinge arrangement containing torsion spring With the upper articulation of backrest, under the active force of torsion spring, headrest cage plate is rested on behind backrest forward；When neck presses rearwardly against head During pillow, headrest can tilt backwards, when rear pressure reduces, the backswing forward in the presence of torsion spring of resting the head on.The rear end of two handrails leads to The middle part for crossing the hinge arrangement containing torsion spring and backrest is hinged, and is fixed limiting plate in the side plate of backrest, is made the up and down model of handrail Enclose and limited；When holding handrail is anterior exerts oneself upwards, handrail can be lifted up, and handrail is then fallen when loosening.Seat board bottom It is hinged by double rocking arms and the pedal backbar of one group of folding, torsion spring, active force of the rocking arm in torsion spring is installed additional in upper hinge Under, in the state of tilting backwards；When the pedal being hinged with support beam front end is trampled forward with unclamping, pedal and supporting Liang Ze is moved forward and return.The carrying roller of multigroup outsourcing flexible material is housed on backrest, can be therewith when pressing backrest backward Roll.

The beneficial effects of the utility model are：The basic function of seat is constant, people can after work or work Between the free time, without leaving seat, at any time can movable psoas and lumbar vertebrae, musculi colli and cervical vertebra, upper limbs and shoulder muscle, lower limb close Section and lower limb muscles, are prevented or waist pain-relieving, lumbar muscle strain, lumbar vertebrae cervical spondylosis, neck-shoulder pain etc..
