Description
Technical field
The present invention relates to field of furniture, more particularly to a kind of chair with Lumbar regulatory function.
Background technology
Inferior health is always problem concerning life of concern, wherein, because sitting gives people the lumbar vertebrae problem particularly frequency for bringing
It is numerous, it is well known that human spine is S-type, and now seat the chair back be typically all be up and down it is straight, or in the chair back under
Portion to be had slightly arch upward to improve the comfortableness that chair back is supported, but the chair of these structures all can not be to the S type ridges of human body
Post is preferably supported, and the general back-supported angle of chair of these structures is unadjustable, it is impossible to meet individual difference, because
This can not solve the problems, such as the vertebra that sitting brings to user.
Although the chair of Lumbar has been carried in currently available technology, under the position of Lumbar is normally in chair
Portion, and the length of Lumbar is shorter, adjustable range is limited, and Lumbar width is wide, it is impossible to is pointed to the vertebra in the middle part of human body and is formed
Preferably support, influences support effect.
The content of the invention
In order to solve above-mentioned technical problem, it is an object of the invention to provide a kind of chair with Lumbar regulatory function,
The regulation stroke range of the Lumbar of the chair is bigger, and the support to waist is more prominent, the effective pressure for reducing upper limbs to lumbar vertebrae
Compel.
In order to realize foregoing invention purpose, present invention employs following technical scheme：
A kind of chair with Lumbar regulatory function, including the chair back, seat support and footing, the chair back are provided with cavity, the chamber
Internal top is provided with support member by lifting device for folding, and the device for folding that lifts includes fixed plate and linking arm, the fixed plate
It is hinged with linking arm, and the fixation of at least two linking arms is synchronized with the movement by the block that is rigidly connected.
Preferably：The fixed plate is fixed with the chair back, and the block that is rigidly connected is fixed with support member, the fixation
The two ends at the middle part of plate turn down to form fixed arm to homonymy, and the side of the fixed arm is additionally provided with cover plate, and the linking arm is hinged
In the cavity that fixed arm and cover plate are formed.
Preferably：Pawl block is also hinged with the fixed arm, ratchet wheel block is fixed with the linking arm, it is described
Reset groove is provided between pawl block and ratchet wheel block, the both sides of one end of the cover plate are provided with gear edge, and two gears are spaced between
Locating piece is provided with, spring leaf is additionally provided with the fixed outer block, the middle part of the spring leaf is located at an outside for locating piece, described
The two ends of spring leaf are respectively positioned at the inner side of another locating piece and the inner side on gear edge, and the bullet on the inside of another locating piece
Reed is folded upward at being offseted with pawl block.
Preferably：The height of the cavity is more than the 70% of chair back whole height.Because housing depth is higher,
So that the length of support member is larger, and the top of support member is hinged with the chair back, so that no matter support member is being indulged in upset
To or horizontal direction on adjustable range it is wider.On the other hand because the length of supporter is more long, even if therefore being turned in supporter
Produce to provide during lumbar support, human body back can also be leaned on supporter and more fitted, more comfortably.
Preferably：The chair back front upper is provided with headrest, and the cavity is arranged on the lower section of headrest, the chamber
The height of body is more than the 60% of chair back whole height.
Preferably：The width of the cavity is the 30%-80% of chair back overall width.Cavity width determines support
The width of body, support effect when supporter is narrower to the backbone of human body becomes apparent from, and supporter it is wider when, supporter is to human body
The stress of backbone is not obvious, and effect is bad.
Preferably：The support member includes upper end and supportive body, and the thickness of the upper end is support master
The 1/4~1/2 of body thickness, and pass through the first cambered surface transition between upper end and supportive body.The structure of support member causes to lift folding
Device can be fixed on the outside of support member, and the maintenance be easy to support member or lift device for folding is changed.
Preferably：The supportive body lower end passes through the second cambered surface transition from the front to the back.With turning over for support member
Modulation section, the bottom of support member is continually changing with the contact position of human body waist, and the bottom of support member uses cambered surface transition
Can guarantee that support member is fitted all the time with human body waist, by more comfortable.
Preferably：The shape of the supporter matches with the shape of cavity, and supporter shape and the chair back
Global shape is consistent.
Preferably：The device for folding that lifts is rotated using gas bar or air bag drive connection arm.
Be arranged on support member in cavity by setting cavity on the chair back by the present invention, by lifting device for folding and chair
The back of the body is hinged, realize the chair back lumbar support regulation, and lift device for folding multiple linking arms fix be synchronized with the movement, reduce support
The risk that body rocks when in use.
