Problems solved by technology

[0003] For example, in the existing mesh chairs, in order to improve the comfort of the waist, the middle part of the chair back can be pushed against the waist of the human body as much as possible. These are all costly and complex in structure; some improve the structure of the back frame so that the waist of the back frame is designed to be lordotic, and the mesh cloth stretched on the back frame can form a lordotic lumbar support, which is relatively simple in structure and can The waist support effect is realized by changing the shape, but with such a shape, due to the tension of the mesh, the mesh in the middle of the back frame will be very loose, which will reduce the elasticity of the waist support of the mesh, and the effect of the waist support will be compromised. For example, if the mesh in the middle of the back frame is also in a stretched state, it needs to be improved through the process, but this will increase the complexity and cost of the structure

Embodiment 1

[0033] Embodiment 1: An ergonomic 3D waist support mesh chair of the present invention, such as Figure 1-6 As shown, it includes a seat back frame 1 and a mesh cloth 2 attached to the seat back frame 1. The seat back frame 1 is made of plastic injection molding, and there are card slots (not shown) around the seat back frame 1. The four sides of the seat are fixed in the card slots around the seat back frame 1 through moldings (not shown).

[0034] In order to meet the needs of ergonomics, the seat back frame is designed as an S shape as a whole, and correspondingly, the middle and lower part of the seat back frame 1 is in the shape of a front arch, and the mesh fabric forms an arched lumbar support 3, the chair The middle part of the back frame 1 is provided with a limit seat 4 in the shape of a rear arch, the middle part of the mesh cloth 2 is provided with a pulling seat 5, and the rear end of the pulling seat 5 is connected with the limit seat 4 through a pulling belt 6, ...

Embodiment 2

[0041] Embodiment 2: the difference between this embodiment and embodiment 1 is: as Figure 7-10 As shown, the rear end of the pulling seat 5 is directly connected to the limit seat 4 and fixed, and the mesh cloth 2 is kept in a tight state under the effect of the pulling seat 5 being stretched backward.

[0042] Furthermore, a connecting hole 20 is provided in the middle of the limiting seat 4, and after the rear end of the pulling seat 5 abuts against the limiting seat 4, a screw 19 is fixedly connected with the pulling seat 5 through the connecting hole 20; specifically In other words, the tie bar fixing part 14 is fixedly connected with the middle part of the tie bar 13, the tie bar fixing part 14 is a box body with an open front end, the back end of the tie bar fixing part 14 is provided with a screw hole 21, and the screw 19 passes through the connecting hole 20 Screw it into the screw hole 21 of the brace fixing part 14 to fix it, so far the brace fixing part 14 is conn...

Abstract

The invention discloses an ergonomic 3D waist-protecting mesh chair. The ergonomic 3D waist-protecting mesh chair comprises a chair back framework and mesh cloth attaching to the chair back framework,wherein the middle-lower part of the chair back framework is in the shape of forward arch, a limiting base in the shape of backward arch is arranged in the middle of the chair back framework, a traction base is arranged in the middle of the mesh cloth, the rear end of the traction base is connected with the limiting base through a traction belt, and the mesh cloth is in the tightened state underthe backward stretching effect of the traction belt. The middle-lower part of the chair back framework is in the shape of the forward arch to form a waist cushion, and the chair back framework is S-shaped in the whole, so that the ergonomic dimensional requirement can be completely satisfied; and meanwhile, the relaxed part in the middle of the mesh cloth is pushed and pressed by the traction baseand pulled by the traction belt and then is clamped at the limiting base, then the middle relaxed part of the mesh cloth is in the tightened state, the waist cushion formed by the middle-lower part of the mesh cloth is also in the tightened state, and thus effective and stable support is formed for the waist of the human body.

Description

technical field [0001] The invention relates to the technical field of seats, in particular to an ergonomic 3D lumbar support mesh chair. Background technique [0002] As an indispensable product in office furniture, the ergonomic 3D waist support mesh chair is loved by consumers for its good air permeability and comfort. The ergonomic 3D waist support mesh chair became popular at the end of the 20th century, and its technology and materials have made great breakthroughs. High-end and low-end prices vary widely, as is comfort. The problem of how to simplify the process and improve the comfort needs to be solved urgently. [0003] For example, in the existing mesh chair, in order to improve the comfort of the waist, the middle of the seat back can be pushed up to the waist of the human body as much as possible. These are high cost and complex in structure; some of them have improved the structure of the back frame, so that the waist of the back frame is designed to be conv...
