Description
Technical field
The present invention relates to a kind of backrest reclining structure that supports the human body waist, mainly be group is located at seat one side the backrest guiding mechanism in use, can can be beneficial to the gravity of human body back against being adjusted to best comfortable orientation by easy operation, and make the back can with regulate after backrest form fully and recline, and once again the backrest guiding mechanism is carried out the orientation and set firmly, thereby reach the adjusting group body of effective simplification backrest and promote comfort level on using.
Background technology
Existing chair tool is in the use for allowing the user can obtain best comfort level when being seated in, relevant dealer just will consider the mechanism that movable adjustment is set when making this class chair tool, so that the seat cushion unit of chair tool, chair back unit, armrest unit ... can be according to using the suitable position adjustments of required work, motor-driven function when using to promote the chair tool, and help to promote comfort.
As a relevant dealer propose in October in 2009 Granted publication on the 21st the patent No. be " the adjustment structure of the chair back " utility model patent that 200820180047.0 group is located at seat one side, this chair back is adjusted the chair back adjustment unit that structure comprises the butterfly seat rear that is assembled in seat, it adopts the axle center with outer toothed portion to be plugged in body and revolves between the endoporus of the back of the body, again elastic parts is set in axle center one side, with the solid assembly of spiral shell lid is locked on body, the place, axle center that faces by the body outside then is arranged with pressing piece again.According to this, will push away in the pressing piece, then the outer toothed portion in axle center can detach the restriction of the internal tooth portion of revolving the back of the body, makes to revolve antiform and become free state can do the adjusting of unspecified angle.After decontroling pressing piece it is resetted, the elastic parts that is set in axle center one side then forms outer support shape, makes the outer toothed portion in axle center be subjected to revolving the restriction of the internal tooth portion of the back of the body once again, revolves antiform and becomes the strong fix state thereby make.
Though above-mentioned chair back adjustment unit can make seat can reach the angular adjustment of chair back expection in use, but the front and back position that this chair back carries out is regulated only partly can form with the people back and is contacted, and the member of this chair back adjustment unit is rather various, make in assembling comparatively complicatedly, cause the whole cost of seat to improve relatively.
Summary of the invention
At the problems referred to above, main purpose of the present invention is to provide a kind of effectively simplified structure, and can promote the backrest reclining structure of the support human body waist of comfort.
For achieving the above object, a kind of backrest reclining structure that supports the human body waist provided by the present invention, for being arranged on the backrest guiding mechanism of seat one side, it comprises the one group of spring section of nothing control module that is located at seat bottom butterfly seat end, and the described spring section of nothing control module guiding is positioned at the parts that pin down of backrest one side of described seat and removes locking or apply locking; It is characterized in that: the support plate lower end of the carrier that the described spring section of nothing control module rear side forms and a default wide cut and development length sets firmly, the last paragraph spacing of leaning on of described support plate forms two hollow pipeline sections, with be arranged on described backrest rear side center of gravity position one connect that pipeline section is parallel to bridge, two hollow lids are introduced along the hollow pipeline section of described support plate respectively, and be positioned in the connection pipeline section of described backrest, one axostylus axostyle runs through two described hollow lids, the connection pipeline section of described backrest also locks with nut at the other end, described backrest and described support plate are pivoted, in place being inserted in a side inwardly of hollow lid of being inserted in two hollow pipeline sections of described support plate has appropriate flexible torque spring, a described torque spring pin contact wherein is at the rear side of described backrest, and another pin contact is at described support plate rear side; Described backrest guiding mechanism is when regulating the position of described backrest, be to form free state to pull the described spring section of nothing control module on the hand to remove locking, order about the backrest that is hubbed on the described support plate and can preset the adjusting in orientation by the gravity contact of human body back, when arriving required contact orientation, back, press down the described spring section of nothing control module with hand again and reply and be locking condition, reach definite orientation and set up being hubbed on backrest on the described support plate; Pull perhaps and be free state, make described backrest along with the docile displacement of human body back.
In the technical scheme of the invention described above, the forward and backward side of described support plate covers plate body against being provided with the forward and backward side that form conforms to, described forward and backward side covers plate body and two hollow pipeline sections and the bottom of described support plate can be covered as the orientation at two ends up and down, and consolidates assembly with several spiral shells described forward and backward side is covered the default position that plate body is installed in described support plate.
Described front side covers plate body and is formed with open-work at the connection pipeline section of the described backrest of correspondence and two hollow pipeline section places of described support plate, regulate in order to the activity between described support plate and the described backrest, described rear side covers the plate body lower end and forms a saturating dummy section, with when being covered in described support plate lower end, can be beneficial to the carrier locking that the solid assembly of spiral shell leans on described support plate and the described spring section of nothing control module back one side, or be convenient to retract the solid assembly of described spiral shell in the future, the bottom spacing extension that described rear side covers plate body is provided with two protuberances, with when a L-shaped plate body is resisted against described dummy section, two described protuberances can be cut the hole of relevant position on the described plate body.
Backrest after adopting back that technique scheme, the present invention can make human body and regulating forms fully and reclines; Perhaps make backrest be in free state, make backrest along with human body back is done docile displacement, allow the user obtain the comfortable effect of lying and leaning on, with avoid because of for a long time fixedly sitting posture produce and have a pain in the back, and backrest guiding mechanism of the present invention has effective simplified structure, definitely reduces the effect of seat integral body cost.
