Description

1 TARIFF INNOVATION IN OFFICE CHAIRS TECHNICAL AREA 5 The invention relates to the field of seating furniture design and manufacturing technologies. The invention is for offices. regarding the load-bearing frame structures, integrated mechanisms and ergonomic features of their seats It offers an improvement, particularly in terms of the lightness of the load-bearing structure and the integration of mechanisms. 10 The focus is on modular and integrated production processes for office chairs. Technical advantages of using these structures include ease of assembly, cost savings, and durability. It aims to provide this. STATE OF THE ART 15 Office chairs are designed to meet ergonomic, durable, and aesthetic needs during long periods of sitting. It is produced with various designs and mechanisms aimed at this purpose. In current technology, the carrier body Their structures are generally made of metal or plastic materials, providing ergonomic support and comfort. Its elements include sponge fillings, adjustable mechanisms, and fabric coverings. However, these products generally require more than one fastener. This situation both complicates production processes and increases costs. It increases. Many office chairs on the market have heavy mechanisms and metal frames. Therefore, it exhibits limitations in terms of portability and compactness. It has a plastic body. While seats generally offer the advantage of being lightweight, they also offer limitations in terms of ergonomics and durability. They fail to deliver the desired performance. Furthermore, a large portion of the current products are limited. Because it does not offer sitting position support and functional flexibility, it is not suitable for different users. It is failing to adapt to their needs. 30 Another deficiency in the current state of the art is the mechanisms and fasteners. The aesthetic integrity is compromised due to its visible positioning. Hidden or designs with integrated mechanisms are limited in number, and such designs Generally, high costs make it difficult to reach a wide user base. 35 It exists. In this context, improving ergonomics in existing products and reducing costs, 2 making the load-bearing structure lightweight and durable, while also combining aesthetics and functionality. More innovative solutions are needed to provide these. In the known state of the art, the useful invention entitled "Seat" with application number TR 2023 / 004563 The model application states, "The utility model relates to a chair furniture and, more specifically, to a user's 5..." It refers to an office chair that provides a comfortable position and has a reclining backrest. A chair is a a backrest and a carrier base and a carrier box that are functionally attached to the backrest. a base with a central support into which a swing mechanism is inserted It includes a seat positioned on top of the box, with an elastic band extending from the base. The plate is fixed and a rotating 10 is inserted into the body of the backrest through the transversely curved plates. By means of the connection, the axis of the rotating link will be mid-height of the backrest. It is connected in this way. A gasket is placed between the transverse plates and the upper part of the backrest body. It has a lifting unit. On the elastic plate, the backrest's starting position is adjusted. To adjust it, there is an element consisting of a box and a screw. The design of the seat varies. "It provides a comfortable position for the user's back when coming to sitting positions" 15 It is summarized. Another known instance of the art is the “Multifunctional” project with application number TR 2016 / 12276. The utility model application titled "Office Chair Set" states that "The invention provides users with a comfortable..." It is a multi-functional office chair developed for seating and use, with a headrest of 20 cm. (4) movement, 3D armrest (3) system, backrest movement and locking system, seat backrest (2) depth and height adjustment system and customizable options to ensure user comfort. It includes an adjustable left knob (8) that provides back ergonomics.” In conclusion, the existence of the above problems and the inadequacy of the current solutions are related to technical issues 25 This has made it necessary to make improvements in this field. THE PURPOSE OF THE INVENTION The present invention meets the aforementioned requirements and eliminates all disadvantages. 30 This is about office chairs, which offer a lift and some additional advantages. The invention aims to combine ergonomics, durability, and aesthetics in office chairs. The aim is to provide a seating solution that meets user needs by bringing together the support structure of the seat. The aim is to design its structure in a lightweight, compact and durable form. Also, 35 By integrating the mechanisms, both assembly and production are facilitated. The aim is to reduce costs. 3 The invention aims to create aesthetic integrity and different seating arrangements thanks to concealed mechanisms. It aims to offer functional flexibility that adapts to their positions. Sponge by eliminating the need for manual handling, providing comfort solely through fabric stretching. This approach aims to combine the advantages of environmental sustainability and lightness. It aims to present. In addition, the modular structure of the chair simplifies production processes. Minimizing the use of fasteners and offering a user-friendly design. The aim is to provide a modern workspace with a seating solution that is both aesthetic and functional. The aim is to meet the needs of these areas. The structural and characteristic features and all the advantages of the invention are given in the figures below.
