Description

The present invention relates to the structure of a chair member, said chair member refers to the backrest or seat portion connected to the chair, and particularly refers to the chair member structure with net as the main support.

A chair is a member that provides support to a person sitting on it, and most of the manufacture, including the backrest or seat, is made of leather, fabric wrapped with foam cotton as a support, and fixed on the bottom plate to provide comfortable support. However, it does not have good air permeability, so in the later period, a soft material such as a net was developed as the main support, assembled into a hollow frame, and used as the main support of the chair. A member that provides the back or buttocks of the human body to lean against. The ventilation and ventilation of the net body are good, and it is possible to remarkably improve the stuffiness and uncomfortable feeling of those who use the chair for a long time.

However, it is not easy to assemble the mesh body with significant gaps and the frame of the chair into a chair member such as a backrest or a seat. With the conventional simple nailing and stitching technique, the force applied to the mesh by the human body cannot be fully received, and therefore the joining edge of the mesh and the frame often detach. , if it is based on the complicated mechanical structure assembly design, it not only has a high failure rate during manufacturing, but also requires time and labor for assembly, and cannot meet the mass production work of the factory.

In addition, the structural element that completely supports the human body with the net body, especially the part where the seat of the chair supports the thighs, makes the person obviously feel uncomfortable for a long time due to the nearly rigid frame.
