1 TARIFF AN ANTI-SAGGING METHOD IN OMEGA-BASED CEILING ARCHITECTURES. ROLLING TRENCH Technical Area This invention improves antenna placement, field of view, and... in vehicles with panoramic glass roofs. Style that may arise in omega-shaped structures due to visual improvements Omega-structured ceiling 10, which improves risks and ceiling architecture. In their architecture, this relates to a ceiling band that prevents sagging. Previous Technique In vehicles manufactured with sheet metal and roof rails, from the production of the first part in the mold, In vehicle roof architectures, sagging occurs from the side frame towards the middle section. This can be observed. In Omega-structured ceiling architectures, glass ceilings are combined with sheet metal. This sagging at the ceiling joint, especially in the middle section, is visible to the eye. easily visible gaps and profiles that can cause production stoppages. 20 It causes problems. In the current technique, aluminum structures are joined together using a riveting method to form a medium. The aim is to prevent potential subsidence problems in the region. Other alternatives include placing the omega structure as close to the center as possible. This involves holding or using a hot-formed part. The applications in the technology are detailed in the Korean patent document numbered KR101585469. Increasing the physical strength of ceiling structural elements integrated with the glass ceiling. It is related to the system. Here, a sunroof installed in the roof of the vehicle 30 a support structure for the deflector and, more specifically, a hinge pin 2 a locking mechanism that is rotatably connected to a deflector arm via his arm to one end of a deflector spring when the vehicle's sunroof is opened It is characterized by being fitted and thus preventing the deflector arm from moving downwards. The text refers to a support structure for a skylight deflector. The applications in the field are detailed in the European patent document numbered EP4269086. A system that solves gap, form, and durability problems in vehicles with glass roofs. It is related to the perfect bonding of two glass layers together. glass ceiling joining including the necessary details for joining methods are mentioned. 10 Applications in the field include United States patent number US5715981. The document mentions an omega-section ceiling rail system. Brief Description of the Invention 15 The aim of this invention is to meet the necessary technical parameters (1-Minimum section depth, 2- Ensuring section continuity, 3-radius values ​​and 4-referencing strategy. The aim is to prevent subsidence in the central region in this situation. Detailed Description of the Invention The "Omega-structured ceiling" was created to achieve the purpose of this invention. Their architecture includes a ceiling band that prevents sagging, as shown in the attached figures. Figures; 25 Figure 1.

The invention, which provides sectional resistance, prevents sagging in omega-structured ceiling architectures. a preventive roof belt (1), - located at the junction between the vehicle body and the roof, and gap profile problems that may occur during glass ceiling installation a roof belt body in the shape of an omega (“Ω”) that enables the removal of the problem 25 (2), − a roof belt body (2) that continues continuously along its length A "U" shaped indentation with a depth of no less than 12.5 mm. section (3), 4 − section section (3), recess with the joints to the ceiling belt body (2) having circular sloping areas within its form and a minimum of 4 – Radius regions with maximum radius values ​​of 8 (4), - joining the roof belt body (2) to the vehicle body by welding 5 points which are aligned with the center of gravity (G) of the roof belt body (2). referencing points remaining within a line (5) It includes. In Omega-structured ceiling architectures, it supports the ceiling and increases the boxing and sectional resistance by 10. The most important element providing inertia is the ceiling belt, which is the subject of the invention (1). For this reason, inertia By providing the correct cross-section, sagging and collapse are prevented while loading the glass ceiling. It eliminates potential gap profile problems. To achieve this... The minimum parameters are as follows: 1. The section of the roof belt body (2) that continues along its length is 15 (3) minimum depth should not be less than 12.5 mm, 2. The cross-section section (3) should continue along the length of the roof belt body (2). and it must come out of the side frame structure, 3. Radius regions (4) have minimum radius values ​​of 4 – maximum 8. It should be and should be a maximum of 6 mm if feasibility permits, 20 4. In the strategy of determining the locations of the reference points (5), this referencing points (5) roof belt body (2) weight of part It must remain within a line aligned with the center (G). The following technical explanations concern the importance of these parameters within the scope of the invention: 25 It is possible: 1- Section depth (3): Section depth above the roof belt (1) (3), the depth of the cross-section located at the bottom of the surface copying the ceiling, rigidity It is very important in terms of ensuring the connection. The line that provides the connection with the side frames. The minimum cut depth required throughout should not be less than 12.5 mm. 30 2- Continuity of the section (3): The section above the roof belt (1) (3), the continuity of the radii in the lower region must absolutely not be disrupted. Otherwise Under load, stretching will occur in the relevant areas and the plastic will react accordingly. Because it will remain at one point, the gap will cause a profile problem. This in addition, the continuity of the surfaces connecting the radii is not disrupted, 5 It is very important that it continues along the same surface. Otherwise, the load and the loading will be... During this process, fractures will occur at points where continuity is broken, and the plastic will become damaged. This will cause a change in shape and consequently a gap profile problem. 3- Minimum radius value requirement: 10 of the ceiling belt (1) section (3) The inertial section should be preserved or increased as much as possible without compromising rigidity. It is necessary. At this point, potential risks that may arise due to project feasibility reasons. It is important to prevent cracks in the radial regions (4) radial Rigidity should be maintained by keeping the values ​​between a minimum of 4 and a maximum of 8. 4-Strategy for determining reference points (5): Ceiling zone (1) Due to its form, the center of gravity (G) of the part is not at the center of the part; it is asymmetrical. This For this reason, the strategy of determining the part reference points (5) is very important. This strategy of determining the reference points (5) determines the center of gravity of the part G) If it does not contain this, it will experience forward tilting in the X-axis. The tolerance for these tilts is 20. This will cause external loads and lead to gap profile problems. will provide. The referencing strategy applied to the individual part will be intermediate, complete and final. The chain must continue in the same way on the body without breaking. To prevent the technical problem from occurring, the above-mentioned measures should be taken. Ceiling belt (1), ceiling boxing through the necessary parameters, The system needs to function as a whole. In order for this system to be established... The necessary precautions should be taken from the very first step of the design process. Currently, fuselages are being produced on the Biw lines. Fuselage production is in its final stages in 30 days. As it approaches, the roof belt (1) is loaded onto the fuselage and welded. This 6 After the welding process, the ceiling is finally loaded and the welds in the relevant area are removed. By doing this, the system is enabled to behave as a whole. At this point, the effectiveness of the invention... These parameters, which are crucial for its operation, must be perfectly balanced. If implemented, it prevents sagging and reduces the criticality of production stoppages. The risks that could arise will be prevented. 5 Around these fundamental concepts, the subject of the invention is "Omega-structured ceiling architectures". a wide variety of applications related to a sag-preventing ceiling belt (1)” It is possible to develop further, and the invention cannot be limited to the examples described here. It is essentially as stated in the requests. 10
