Abstract
The utility model discloses an adjusting mechanism of a backrest, which comprises a back cushion, a support of a chair, and arm supports which are connected between the back cushion and the support. The arm supports are respectively provided with two opposite ends, the two opposite ends respectively comprise a first connection part and a second part, the first connection parts are connected with the support, and the second parts are connected onto the back cushion; and the adjusting mechanism of the backrest is characterized in that: the arm supports are respectively provided with an arc bending part which is between the first connection part and the second connection part, the back cushion is stressed to guide the arm supports to deform towards the direction of the support, and the return elastic force is also generated to the back cushion, so the back of a user can be well fit with the back cushion, and better support is realized.
Description
Technical field
The utility model has a kind of chair tool of relation, refers to a kind of back of chair regulating mechanism that can produce the subsides back of the body from command of execution back pad especially.
Background technology
The chair tool is the articles for use of an indispensability in the daily life, no matter be at home, dining room or workplace, the chair tool that all can see different purposes exists.
The chair tool is except pursuing different practicality, and maximum requirement is its comfort level; General chair tool design, its backrest and cushion mostly are integral type, though can adjust luffing angle, are connected as a single entity for fear of backrest and cushion, make the support that produces subsides back of the body formula between backrest and the user that certain degree of difficulty is seemingly arranged; Again, utilize く font support that backrest and cushion are carried out the adjustment of separate type, the design of backrest is still adopted fixed, also can't satisfy the user and require to paste the demand that back of the body formula supports and influence its comfort level though TaiWan, China is announced No. 223773 patent.
The utility model content
At above-mentioned shortcoming, main purpose of the present utility model is to provide a kind of and can more fits in back pad from command of execution user's back and obtain the back pad guiding mechanism of preferable support.
For reaching above-mentioned purpose, the utility model provides a kind of back pad guiding mechanism, mainly comprises back pad, the support of chair tool, and be connected jib between back pad and the support.Described jib has two opposite ends, and these two opposite ends include first connecting portion and second connecting portion respectively, and this first connecting portion links to each other with support, and second connecting portion then is connected on the back pad; Particularly, this jib possesses arc between first connecting portion and second connecting portion and turning point that can produce back stretch to back pad, and back pad is out of shape towards holder orientation at stressed this jib of back guiding.
Described first connecting portion possesses the elasticity of plastics external member, and an end of described support has hollow bulb, and this elasticity of plastics external member penetrates described first connecting portion in location in this hollow bulb.
Moreover the pivot that can provide luffing angle to adjust for back pad is provided aforementioned second connecting portion, this pivot shaft to two ends be connected on the back pad.
Preferably, described jib is being provided with draw ring near described this end of first connecting portion.
The utility model is connected a jib between the support of back pad and chair tool, this jib utilizes the turning point of an arc to make it produce deformable elastic force, design by this jib, back pad is out of shape towards holder orientation at stressed back guiding jib, and, can more fit in back pad from command of execution user's back and obtain preferable support the elastic force that back pad generation one is replied; Backrest is more comfortable in the time of also can allowing this chair tool of use because of the extension of this back pad.
