Holding is provided all the time when facing upward lying posture gesture.
Above-mentioned technical purpose of the present utility model technical scheme is that：
A kind of adaptive backrest seat, including backrest, seat, chair leg and the backrest support frame for installing the backrest,
The backrest includes shoulder and carries on the back butting section and the raised waist butting section of cambered surface, in addition to backrest adjusting part, the backrest regulation
Component is included by changing the vertical range between the bottom of the backrest and the backrest adjusting part with described in flexible adjustment
Angle between backrest and the backrest support frame.
Found by the long-term research of applicant and practice, in above-mentioned documents or other similar tools in the prior art
There is the seat for facing upward function of lying, the waist of user can still feel fatigue and be the reason for uncomfortable during long-term use, initially sit
Appearance（Generally user is the initial sitting posture that straight sitting posture state is seat）During position, backrest has one to the waist of user
It is fixed against support effect, this effect according to human body waist curve to backrest mainly by being arranged to curvilinear plane；However as
Face upward the beginning for action of lying, the double backs of user firmly against backrest and tilt down backrest, now user
Waist forms curves different during from initial sitting posture, it is normal for this curve radian be more than the lumbar curve of initial sitting posture
Radian, and because the curve of backrest immobilizes, thus the waist of user loses backrest with the progress for facing upward action of lying
Support and support；Holding also no longer backed support and support when facing upward lying posture state, double backs coordinate with upper body weight to be held against
Dorsad descend and when facing upward lying posture state of seat, waist not only needs to make power and do not have backed support and support, after long-time use,
There is fatigue and uncomfortable in waist.
In the technical program, adaptive backrest seat includes the backrest of a prior art, the backrest include shoulder carry on the back against

Bottom and the backrest support frame between vertical range, so as to have adjusted between the backrest and the backrest support frame
Angle, with keep the abutting relation at the backrest and user back it is whole face upward lie during keep constant.
As the preferred of above-mentioned technical proposal, the top of the backrest is corresponding to be fixedly installed on the backrest support frame
Top；The backrest adjusting part includes the compression bullet between the bottom of the backrest and the bottom of the backrest support frame
Spring.
As the preferred of above-mentioned technical proposal, the compression spring two ends are respectively and fixedly connected to the bottom of the backrest and described
The bottom of backrest support frame.
In the technical program, a compression spring in compressive state is arranged at the back-rest and the back rest supports
Between frame, specifically it is arranged between the back-rest bottom and the backrest support frame bottom, with the reset of compression spring
Trend and reset force change the distance between the backrest bottom and described backrest support frame, because company is fixed on the two top
Connect, so as to change relative angle therebetween, specifically this angle becomes big.
As the preferred of above-mentioned technical proposal, an end of the compression spring is installed in institute by the first installation pedestal
State the bottom of backrest；Another end of the compression spring is installed under the backrest support frame by the second installation pedestal
Portion.
As the preferred of above-mentioned technical proposal, the backrest adjusting part also includes being used to control the backrest amplitude of accommodation
Adjustment component.
In the technical program, it is considered to different users' waist flexible toughness and the difference of radian, a tune is preferably provided with
Whole group part, the adjustment component is used for the amplitude of accommodation for controlling the backrest.
As the preferred of above-mentioned technical proposal, the adjustment component includes a screw mandrel, and described screw mandrel one end is fixed on described
In first installation pedestal, the other end set through the adjustment hole in second installation pedestal, separately have a nut and the screw mandrel
Coordinate the length for controlling the screw mandrel to be located at part between the backrest and the backrest support frame.
As the preferred of above-mentioned technical proposal, the aperture of the adjustment hole is more than the external diameter of the screw mandrel.So that described
Screw mandrel can the freely activity in the adjustment hole.
As the preferred of above-mentioned technical proposal, the screw mandrel is located in the compression spring.
As the preferred of above-mentioned technical proposal, what this kind of adaptive backrest seat included that multigroup level is placed equidistant described leans on
Adjusting part is carried on the back, the screw mandrel is included on the active segment being located between the backrest and the backrest support frame, the active segment
The elastic supporting member for supporting optical member being engaged with the compression spring is arranged with, the elastic supporting member for supporting optical member is that a surface has and the compression bullet
The elastic polyurethane sleeve of the consistent helicla flute of spring spiral, the compression spring is embedded in the helicla flute.
