Description

Technological sector of the Utility Model [001] This Utility Model pertains to the furniture sector and refers more specifically to a backrest and seat applied to chairs in general with the aim of providing greater comfort, safety and durability, using high-strength aluminum panels, in addition to generating savings in manufacturing processes, facilitating the replacement of parts for reuse of the frame and/or color changes and boosting sales. State of the Art [002] Current chairs and backrests present a series of technical, functional, economic, and environmental problems that highlight the need for more advanced technical options. From a technical point of view, there is a demand for solutions that are more resistant to wear and tear, do not tear easily, maintain their shape without expanding, and are less susceptible to dirt. In addition, it is essential to develop materials that do not absorb as much heat when exposed to the sun and that allow for quick and efficient drying, even after coming into contact with water, enabling immediate use without the need for long periods of drying in the sun. [003] Functionally, there is a lack of chairs that allow for easy maintenance of the backrest and seat. Currently, most models require the complete disposal of the frame when these parts deteriorate, which makes the development of chairs with replaceable parts essential, allowing the user to maintain the original structure and replace only the worn parts. [004] From an economic standpoint, consumers need options that offer greater durability and the possibility of maintenance, reducing the need to replace the entire chair. This would not only save money but also contribute to reducing waste. [005] Environmentally, the urgency for chairs made with sustainable and recyclable materials is clear. It is crucial that new designs avoid the use of polymers that do not decompose in nature, and that they consider the environmental impact throughout the entire product lifecycle, from manufacturing to disposal. These more advanced technical options could thus mitigate the negative effects that current chairs cause to the environment. Utility Model Updates [006] The use of high-strength aluminum composite panels (ACM) for chair backs and seats offers a number of technical, functional and economic advantages, making it a highly efficient solution for applications in various environments, such as domestic, commercial, industrial, offices, leisure, hospitals, clinics, health centers, as well as vehicles, aircraft and other means of transport. [007] Technically, ACM adds significant value to the final product, providing greater mechanical resistance with a force of 50 kg/cm², durability, and safety for the consumer. With its flexibility, resistance to impact, chipping, pollutants, scrubbing, acids, and alkalis, ACM offers superior performance compared to other materials. Furthermore, it has high resistance to extreme temperatures, ranging from -50 to 95 degrees, a low coefficient of thermal expansion, and a low density of around 4.93 kg/m², making it lightweight and easy to handle. ACM is also available in various high-gloss colors, allowing for customization and greater aesthetic appeal, and is easy to produce and install, allowing for drilling and using fewer manufacturing processes, which reduces costs and increases efficiency. [008] Functionally, chairs with ACM backrests and seats offer several improvements. They guarantee greater durability, do not oxidize, and offer a smooth and comfortable surface that does not absorb heat, facilitating quick drying and immediate use after contact with water. The ease of cleaning and the availability of replacement parts contribute to the product's longevity, while the lightness of the material does not compromise the chair's robustness. In addition, ACM provides a pleasant initial thermal sensation due to heat exchange with the human body. Furthermore, it allows for the elimination of wood used in chair structures. [009] Economically, the use of ACM significantly reduces manufacturing costs due to the simplicity of the processes involved and the durability of the material, which extends the lifespan of the chairs. The possibility of replacing parts, taking advantage of the existing structure and allowing aesthetic changes such as color changes, boosts sales and offers consumers a product with excellent cost-benefit. The combination of high mechanical resistance, gloss, and low weight makes ACM an attractive choice for the production of high-quality chairs suitable for a wide variety of uses.
