The chair frame comprises a seat plate, a seat plate fixing assembly, a backrest, a backrest fixing assembly, a vertical column for bearing weight, a headrest and a headrest adjusting assembly, wherein the seat plate fixing assembly and the backrest fixing assembly are directly or indirectly fixed on the vertical column; the headrest is hinged with the backrest; the headrest adjusting assembly comprises a first connecting rod, a second connecting rod and an L-shaped member; one end of the first connecting rod is fixedly connected with the headrest, and the other end of the first connecting rod is movably hinged with the second connecting rod; the second connecting rod is movably hinged with the L-shaped member; the L-shaped member is movably hinged with the backrest fixing assembly. According to the chair frame, the angle adjustment problem of the headrest is solved, the headrest can be adjusted from the backrest, and the adjustment is not only convenient but also highly coordinated with the daily operating habits of people.
Description
Technical field
The present invention relates to a kind of chair frame, relate in particular to a kind of headrest and synchronize the chair frame of adjustment with backrest, belong to seat technical field.
Background technology
Comfort level when chair headrest regulates improper meeting impact sit or lie, and uncomfortable headrest easily causes cervical vertebra problem.In prior art, seldom there is the research regulating for chair headrest, and often concentrate in the research of backrest adjusting.The research regulating for headrest in prior art concentrates on field of automobile seats.As the Chinese utility model patent that application number is 201320448463.5, a kind of car seat headrest governor motion is disclosed.It comprises front and back sliding pillow bar assembly, front and back sliding pillow bar mounting bracket assembly, locking rod assembly, manual unlocking assembly and bracing wire unlock component, described front and back sliding pillow bar assembly front end and the continuous assembling of headrest bubble, its rear end is sleeved in the sliding pillow bar mounting bracket assembly of front and back, described front and back sliding pillow bar mounting bracket assembly is fixed on moving up and down on head rest pole of chair framework assembly, it and locking rod component matching, described locking rod assembly and manual unlocking assembly, bracing wire unlock component are equipped.This utility model compact conformation, is convenient to assembling, has two kinds of functions of SAHR and adjustable headrest, has significantly improved comfortableness and the security of vehicle ride.The headrest of common seat and the headrest of automotive seat or distinguishing, the adjusting of automotive seat is the adjusting of highly adjusting instead of angle substantially, because must being suitable for passenger while use, the headrest of automotive seat can face front, to energy is concentrated on and driven above, instead of be placed on whole-heartedly in limbs impression.The problem that relates to the angular adjustment of resting the head on of drawing thus, prior art does not also have good solution.
Summary of the invention
The present invention will solve the problems of the technologies described above, thus the chair frame that provides a kind of headrest to synchronize adjustment with backrest.The technical scheme that the present invention addresses the above problem is as follows:
Headrest synchronize with backrest adjustment chair frame, comprise seat board, seat board fixation kit, backrest, backrest fixation kit and the column for load capacity, described seat board fixation kit and backrest fixation kit are fixed on described column directly or indirectly; Also comprise headrest and headrest adjusting part, described headrest and described backrest are hinged, described headrest adjusting part comprises first connecting rod, second connecting rod and L-type member, described first connecting rod one end is fixedly connected with the other end with described headrest and is movably hinged described second connecting rod, described second connecting rod is also movably hinged with described L-type member, and described L-type member is also movably hinged with described backrest fixation kit.
As technique scheme preferably, described backrest fixation kit is handrail.
The present invention has adopted polygonal unstable principle, and taking wherein, on one side as adjusting edge, other limits all become driven limit.Especially its upper and lower adjacent side, the activity direction of adjacent side is relevant with corner dimension, it is 100 ° such as working as angle, the activity direction of adjacent side and adjusting edge form an angular range so, it may be 80～120 °, also may be 90～110 °, the size of scope is relevant to the amplitude of accommodation, so extremely angle angle trends towards the little stressed directional correlation of large adjusting with adjusting edge that still trend towards.Thus, the present inventor expects, polygonal this feature (the adjusting relation of adjusting edge, adjacent side) is just in time applied to the chair back and the headrest of seat: using the chair back as adjusting edge, to rest the head on and the coupling of adjacent side phase, and suitably regulate the angle of adjusting edge and adjacent side so that this structure can be applicable to the chair back of seat and the coupling formula of headrest regulates.The angular adjustment problem that this has solved headrest on the one hand, makes the adjusting of headrest be promoter from backrest on the other hand, not only easy to adjust, is also accustomed to hight coordinate with people's routine use.As seat, as unadjustable in the chair back, as long as its headrest finds a proper angle to fix so, there is no need to make adjustable; People's sitting posture changes conventionally and the angle of backrest is closely-related, when sitting posture changes the demand that just has adjusting head cornu occipitale degree.And the enforcement of technique scheme of the present invention, in the time of backrest below, headrest is set level gradually, is convenient to people lie down; And in the time that backrest is more and more holded up, its headrest is also and then holded up and is even leaned forward, when meeting people and sitting up straight for the demand of headrest angle.
As technique scheme preferably, described seat board fixation kit comprises that a fixing brace, one end are set in the described fixing brace other end and are fixed on the sliding sleeve of described seat board and lock the knob of described sliding sleeve.
As technique scheme preferably, described fixing brace is connected in described column.
As technique scheme preferably, described backrest fixation kit is handrail, described fixing brace is connected in described handrail.
As technique scheme preferably, also comprise chassis, described column fixing with described chassis.
As technique scheme preferably, described backrest, first connecting rod, second connecting rod and L-type member, four form a long and narrow quadrilateral structure; Described backrest, described headrest and described first connecting rod hinged with a place, and fixing between described headrest and described first connecting rod.
As technique scheme preferably, described headrest, backrest, first connecting rod, second connecting rod and L-type member, four form a long and narrow pentagonal configuration.
As technique scheme preferably, described seat board and described backrest are hinged in its junction.
The present invention has following beneficial effect:
The present invention, using the chair back as adjusting edge, will rest the head on and the coupling of adjacent side phase, and suitably regulate the angle of adjusting edge and adjacent side so that this structure can be applicable to the chair back of seat and the coupling formula of headrest regulates.The angular adjustment problem that this has solved headrest on the one hand, makes the adjusting of headrest be promoter from backrest on the other hand, not only easy to adjust, is also accustomed to hight coordinate with people's routine use; In the time of backrest below, headrest is set level gradually, is convenient to people and lies down; And in the time that backrest is more and more holded up, its headrest is also and then holded up and is even leaned forward, when meeting people and sitting up straight for the demand of headrest angle.
