Abstract
A net member is stretched over a frame for a seat and backrest of a chair. An engagement member attached to the end of the net member is inserted into an engagement groove on the lower surface of the basic frame. A binding frame is pressed onto the lower surface of the basic frame and the net member is fixed between the basic frame and the binding frame by the engagement piece. Warps are woven or knitted in a mesh structure over the seat and backrest to wefts comprising elastic yarns and chenille yarns.

A structure for mounting a net to an element of a chair, the structure comprising:
- a basic frame for supporting the element of the chair, the basic frame having a peripheral region and a lower surface provided with an engagement groove into the basic frame from the lower surface;
- a net covering the element of the chair and wrapping around the peripheral region of the basic frame, the net having a peripheral edge;
- an engagement piece attached to the peripheral edge of the net, the engagement piece being insertable, with the net attached to the engagement piece, into the engagement groove of the basic frame;
- and
- a binding frame coupled to the lower surface of the basic frame for mounting the net to the basic frame.
A method of mounting a net to a basic frame for a seat or backrest of a chair, comprising the steps of:
- providing a net having a periphery with an engagement piece secured thereto;
- covering an upper surface and an outer peripheral side surface of the basic frame with the net after the periphery of the net is secured to the engagement piece;
- folding said the net inwardly around the outer peripheral surface of the basic frame;
- inserting the engagement piece, with the net attached thereto, into an engagement groove of the basic frame;
- pressing a binding frame onto a lower surface of the basic frame to urge the engagement piece further into the engagement groove of the basic frame so that a tensile force is applied to the net;
- and
- coupling the binding frame to the basic frame to mount the net to the basic frame.
A chair, comprising:
- a seat and a backrest;
- a respective frame for at least one of the seat and the backrest;
- and
- a mesh woven or knitted over the respective frame, the mesh comprising:
- high-tension warps stretched along a vertical direction or a depth direction of the respective frame;
