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..

Embodiment
Headrest (1) is fixed on headrest cage plate (2), and headrest cage plate (2) connects firmly headrest hinge axis (15), with flap of resting the head on
(14) it is hinged, headrest torsion spring (13) one end connection headrest hinge axis (15), one end connection headrest flap (14), flap of resting the head on
(14) connect firmly on postnotum (16), both ends and the backrest side plate (3) of postnotum (16) connect firmly.Headrest (1) and headrest cage plate (2)
Lean on postnotum (16) forward under the twisting force of headrest torsion spring (13), headrest cage plate (2) is two parts composition of suit, can
With the flexible height with adjustment headrest (1).When neck is firmly pressed against headrest (1) backward, headrest (1) is put afterwards, torsion spring of resting the head on
(13) tightened, when neck relaxes, headrest (1) forward swing under the active force of headrest torsion spring (13), set back.
Backrest side plate (3) bottom is be hinged by the backrest hinge axis (20) and lower support plate (9) connected firmly with it, backrest torsion spring
(21) one end connects firmly backrest hinge axis (20), and one end connects firmly lower support plate (9), and lower support plate (9) connects firmly with seat board (10);Lean on
Equipped with multigroup outside carrying roller (22) for wrapping attached flexible material in dorsal plate (3);Shrouding (17) after backrest side plate (3) is fixed below.
Backrest torsion spring (21) applies the torsion of backrest side plate (3) forward by backrest hinge axis (20) so that rear shrouding (17) is close to
Seat cushion (11);When people, which is sitting on seat cushion (11), firmly to swing back, back compressing carrying roller (22) drives backrest side plate (3) hypsokinesis, leans on
