1 TARIFF SYSTEM DEVELOPED FOR SEAT BACK ADJUSTMENT Technical Area 5 This invention is a mechanism used in seating systems where the back section is fixed. the ability to move around without getting stuck and the possibility of using the chair as a bed It is a complete system developed for adjusting the seat backrest. Its working principle is based on the backrest... It is based on the principle of one part turning backwards to complete a specific rotation. This 10 When the movement is complete, the lower part of the back and the seating surface will be level. State of the Art Many modern chair mechanisms allow the backrest to adjust at only a specific angle of 15 degrees. It allows for leaning back, but this movement ultimately affects the back and sitting areas. A height difference is created between them. This situation prevents the seat from being converted into a bed. When brought in, it prevents the creation of a flat and uninterrupted surface; besides, it affects sleep. This negatively affects comfort. Furthermore, the existing mechanisms are limited. Because it has mobility and fixed attachment points, it offers the user 20 It is inadequate in providing extra sleeping space. Backrest reclining mechanisms produced with current techniques enable seat-bed conversion. It does not offer practical usability during this time. This invention develops mechanisms that enable chairs to be used as beds. The aim is to overcome the problem of limited bed capacity. The existing in systems where the back section cannot be brought to a horizontal position or is in contact with the seating surface Due to their misalignment, the seats form a completely flat bed surface. It is unable to create this; this both reduces comfort and the usable sleeping area. It limits. This arrangement provides an additional mattress the size of the lower back section when the sofa is converted into a bed. This allows the area to be obtained. The mechanism both opens the back section backward and... 2 by keeping this section at the same level as the seat, it allows for an average difference of 20–25 cm. Extra sleeping space is offered. This feature is more functional compared to existing systems. It offers a space-saving solution. In conclusion, due to the negative aspects described above and the current solutions, topic 5 Due to its inadequacy, a system was developed for seat back adjustment. It has been made necessary. Brief Description of the Invention The present invention satisfies the aforementioned requirements while eliminating the disadvantages. with a system developed for seat back reclining that lifts and brings some additional advantages It is related. The primary purpose of the invention is to align the backrest of the seat with the seating level. Thanks to its arrival, it provides approximately 20–25 cm of extra sleeping space compared to existing systems. to provide. Another aim of the invention is to bring the back and seat sections of the chair to the same level. The aim is to increase bed comfort by creating a flat and seamless surface. 20 Another purpose of the invention is to allow the back section to rotate backward in a controlled turning motion. This results in a more balanced and functional mechanical movement. Another purpose of the invention is that, thanks to the special form of the mechanism, the existing seat 25 The aim is to ensure that they can be easily integrated into their systems. Another advantage of the invention is that the user can easily and effortlessly adjust the chair to a bed position. Its advantage is that it can be passed through with a single movement, offering practical usability. Another advantage of the invention is that, despite offering extra sleeping space, the seat... Space efficiency is achieved without causing an increase in volume. 3 Another similar objective of the invention is to make the developed system innovative compared to similar ones. The goal is to create added value in terms of functionality and commercial value. The structural and characteristic features and all the advantages of the invention are given in the figures below.
