specific Embodiment approach

[0041] The directional words such as "front", "rear", "left" and "right" involved in this embodiment are described by the user's field of view after the user sits on the seat. For example, the front of the user is "Front"; for better understanding of this embodiment, the connection line A, connection line B, and connection line C involved are virtual lines.

Embodiment

[0043] A backrest reclining mechanism of a seat functional frame, such as Figure 1-3 As shown, it includes a first backrest auxiliary assembly 510 and a second backrest auxiliary assembly 520 arranged symmetrically on the left and right sides of the fixed frame 100, and the first backrest auxiliary assembly 510 and the second backrest auxiliary assembly 520 are located on the fixed frame The rear part and the front part of 100; the first backrest auxiliary assembly 510 includes a slide rail 511 and a pulley 512 arranged in the slide rail 511 to facilitate the tilting and return of the backrest assembly 400, and the second backrest auxiliary assembly 520 includes a slide rail 512 that facilitates the backrest assembly 400 The auxiliary connecting piece A521 , the auxiliary connecting piece B522 and the auxiliary connecting piece C523 are hingedly connected to each other for reclining.

[0044] Among them, such as Figure 1-4 As shown, the slide rail 511 is fixedly arranged at...

Abstract

The invention relates to a backrest tilting mechanism of a seat function frame, which includes a first backrest auxiliary assembly and a second backrest auxiliary assembly which are arranged on left and right sides of a fixing frame and are left and right symmetrically arranged. The first backrest auxiliary assembly and the second backrest auxiliary assembly are respectively located at the rear and the front of the fixing frame. The first backrest auxiliary assembly includes a sliding rail for facilitating tilting and returning of a backrest assembly, and a sliding wheel arranged in the sliderail, and the second backrest auxiliary assembly includes an auxiliary connection member A, an auxiliary connection member B and an auxiliary connection member C, which are hinged to each other to facilitate tilting and returning of the backrest assembly. Compared with the prior art, the first backrest auxiliary assembly and the second backrest auxiliary assembly are respectively arranged at the front and rear of the fixing frame, and can generate forces on both the front and the rear that are favorable for the backrest assembly to tilt and return. For backrest assemblies on a low function frame, a non-electric function frame and other function frames, the backrest tilting mechanism can run smoothly and save labor during tilting down and returning.

Description

technical field [0001] The invention relates to the technical field of furniture, in particular to a backrest reclining mechanism of a functional seat frame. Background technique [0002] The tilting down and recovery process of the backrest assembly in the traditional seat functional frame has always had problems such as unsmooth operation and laborious recovery to a certain extent. This is also a relatively common problem, especially for a low functional frame, non- Electric function racks, etc., this problem is more prominent. [0003] For the increasingly strong demand of the market, the solution to this problem is also imminent. It is necessary to make a backrest that can make the functional rack include some low-profile functional racks, non-electric functional racks and other functional racks in addition to the traditional functional racks. A smooth, low-effort mechanism for components to function both when tipped over and when they return. [0004] like figure 1 ,...
