Description

Chair structure

Technical field

The utility model relates to a kind of chair structure, refers to a kind of chair structure that meets ergonomics especially, by the connection group corresponding composition cushion and the chair back with different radians, to meet user's demand.

Background technology

General working clan in office, or young students can say so time of contacting with computer more and more longer, so health can be said so very intimate with contacting of chair, and, require more and more higher to chair tool quality, texture also because of the lifting of contact and living standard for a long time.Have much in the chair tool kind of taking that is applicable to that can see on the market, high pin formula, low stool chair, office chair, leisure chaise longue or the like are arranged, the main chair tool that need use in various functions or place that derives on demand, and early stage chair tool is only required the utility function that can Gong take, to now except need possess this utility function, the use or the comfort level or the like of lying of inclining of the outward appearance that possesses uniqueness, the design that meets ergonomics, the ventilative material of still needing can promote competitiveness.

Existing chair structure mainly is made up of cushion portion and chair back portion, and remaining moulding can divide fixed chair pin haply, movable wheel body chair pin or have or not head rest, handrail equipment and take material or the like, again with material, the contact texture of taking and lying and lean on of chair, comfortable have very important association with material, but tool is except surface contact soft comfortable, whether it has the user's of meeting build or custom, comfort in the time of all can causing the user to take, general chair tool is then announced M317211 number a kind of chair structure improvement as TaiWan, China, see also shown in Fig. 7～8, it comprises: a chair frame 4 is formed with arc portion 41 thereon; Several Connection Blocks 5, be provided with to pasting section 51 in its bottom surface, can correspondence be fixed on the chair frame 4, support the ora terminalis that pastes section 51 at Connection Block 5 and extend the frame portion 52 that is provided with, establish several open-works 521 in the frame portion 52, it is fixing to supply elastic strip 6 to wear, and is provided with breach 53 in frame portion 52 places of Connection Block 5 corresponding chair frame 4 arc portions 41 again; Several elastic strips 6, each self-forming stiff end 61 of its two ends can embed in the open-work 521 that is sticked in Connection Block 5.

And above-mentioned chair structure, be straight Connection Block 5 assembling elastic strips 6, and correspondence combines with chair frame 4, the flat that is one of the forming because of this Connection Block 5, therefore the face of the taking of 6 frameworks of elastic strip, backrest is a flat, so that allow the user who takes feel uncomfortable, can't with the corresponding applying of the radian of human body back or buttocks, so the discomfort of taking.And need die sinking separately according to the radian that above-mentioned structure will change it Connection Block 5, and each user's height build difference, need offer many group moulds, therefore unsatisfactory.

In view of this, the design people promptly is in view of the disappearance part of above-mentioned conventional chair tool on reality is implemented to use, and revised, improve, simultaneously in line with spirit of asking and theory, and assisting by professional knowledge, experience, and after clever thought in many ways, test, the side creates the utility model, improves above-mentioned disappearance so that a kind of chair structure to be provided.
