Detailed Implementation

[0034] The following are specific embodiments of this application, which are described in conjunction with the accompanying drawings to further illustrate the technical solutions of this application. However, this application is not limited to these embodiments.

[0035] refer to Figures 1-5 This application provides a seat belt guide ring 100 for guiding the seat belt 200. The seat belt guide ring 100 includes a guide ring body 110 and a buckle 120.

[0036] The guide ring body 110, as the basic structure of the entire seat belt guide ring 100, serves to support and guide the seat belt 200, providing physical support and path guidance for the normal installation and use of the seat belt 200. The guide ring body 110 has a receiving groove 111 for accommodating the seat belt 200, and the receiving groove 111 has a slot 111a for the seat belt 200 to enter and exit. The receiving groove 111 provides a specific receiving space for the seat belt 200, and the slot 111a facilitates the smooth entry and exit of the seat belt 200 from the receiving groove 111. The guide ring body 110 adopts a rigid structure, increasing durability by more than three times, and maintains reliable guiding performance even during large-angle adjustments of the backrest.

[0037] The first end of the buckle 120 is rotatably connected to the guide ring body 110, and the second end of the buckle 120 is engaged with the guide ring body 110 so that the middle part of the buckle 120 covers the slot 111a to prevent the seat belt 200 from coming off during use. The middle part of the buckle 120 is located between the first end and the second end of the buckle 120. When subjected to an impact force exceeding a preset threshold, the seat belt 200 can drive the buckle 120 to rotate and separate the second end of the buckle 120 from the guide ring body 110 to release the impact force. The latch 120 can rotate around the connection point with the guide ring body 110 to achieve opening and closing action; the second end of the latch 120 is engaged with the guide ring body 110, and when the latch 120 rotates to the appropriate position, it can be firmly connected with the guide ring body 110; the middle part of the latch 120 is covered by the slot 111a, so that when the latch 120 is closed, it can cover the slot 111a of the receiving slot 111, which plays a certain role in restricting and fixing the seat belt 200.

[0038] In practical applications, the design of the receiving groove 111 can be achieved in various ways, such as using a U-shaped groove, a V-shaped groove, or other geometric shapes with similar functions. As part of the receiving groove 111, the shape and size of the slot 111a can be adjusted according to actual needs, such as being set as a rectangular opening, an arc opening, or other forms of opening structure, in order to adapt to the installation requirements of different specifications of safety belts 200.

[0039] Furthermore, the rotatable connection between the first end of the buckle 120 and the guide ring body 110 can be achieved in various ways, such as by using a hinge structure, pin connection, or elastic connector, to realize the opening and closing function of the buckle 120, thereby facilitating the insertion of the seat belt 200 or its disengagement in the event of a collision. The engagement between the second end of the buckle 120 and the guide ring body 110 can also be achieved in various ways, such as by using a hook and groove combination, magnetic connection, or elastic buckle structure, to achieve the fixing function of the buckle 120 in the closed state, preventing loosening due to external force. The design of the middle part of the buckle 120 covering the slot 111a can be achieved in various ways, such as by using a flat plate structure, an arc structure, or other geometric shapes that can cover the slot 111a. Its main purpose is to close the slot 111a and prevent the seat belt 200 from accidentally disengaging.

[0040] In this application, the cooperation between the guide ring body 110 and the buckle 120 solves the problem that the seat belt 200 easily comes off the guide ring opening during human movement or large-angle adjustment of the backrest 300. Compared with the unclosed guide ring opening design in the prior art, this embodiment forms a physical barrier by covering the middle of the buckle 120 with the slot 111a, directly blocking the exit path of the seat belt 200, thereby improving the reliability of the seat belt 200. The first end of the buckle 120 is rotatably connected to the guide ring body 110, and the second end of the buckle 120 is engaged with the guide ring body 110. When a vehicle collision occurs, the seat belt 200 will pop out from the buckle 120 to release the force, preventing damage to the guide ring body 110 and the generation of flying debris that could cause secondary injury to the occupant. In addition, the combination of the rotatable connection and the engagement design of the buckle 120 makes the operation of the buckle 120 simpler, while ensuring the stability of the buckle 120 in the closed state, avoiding loosening caused by vibration or external force.

[0041] The receiving groove 111 extends through the guide ring body 110 along the first direction X and extends along the second direction Y. A slot 111a is located at one end of the receiving groove 111 along the second direction Y. The middle part of the buckle 120 is positioned over the slot 111a along the second direction Y. The first direction X is perpendicular to the second direction Y. Specifically, the receiving groove 111 extends through the guide ring body 110 along the first direction X, allowing the seat belt 200 to smoothly enter from one side of the guide ring body 110 and exit from the other side. The receiving groove 111 extends along the second direction Y, which is actually the width direction of the seat belt 200, providing sufficient space for the seat belt 200 and preventing wrinkles. The slot 111a is located at one end of the receiving groove 111 along the second direction Y, providing a clear entry and exit position for the seat belt 200 and also providing a positioning basis for the buckle 120. The middle part of the buckle 120 is positioned along the second direction Y over the slot 111a, directly covering the area of ​​the slot 111a, effectively preventing the seat belt 200 from accidentally dislodging during human movement or seat adjustment. The perpendicular relationship between the first direction X and the second direction Y makes the fit between the receiving slot 111 and the buckle 120 more reasonable, thereby enhancing the overall stability and guiding effect.

[0042] In this embodiment of the application, the guide ring body 110 includes a first support arm 112 and a second support arm 113. The first end of the first support arm 112 in the second direction Y is connected to the first end of the second support arm 113 in the second direction Y and forms a receiving groove 111. The first end of the latch 120 is rotatably connected to the second end of the first support arm 112 in the second direction Y, and the second end of the latch 120 is engaged with the second end of the second support arm 113 in the second direction Y.

[0043] Specifically, the first support arm 112 is a component used to provide basic support structure, and it can be made of metal or high-strength plastic to ensure the rigidity and stability of the overall structure. The second support arm 113 is another support component that cooperates with the first support arm 112 to form a receiving groove 111, and it can be connected to the first support arm 112 by welding, riveting, or integral molding. At the same time, the snap-fit ​​design between the second end of the buckle 120 and the second support arm 113 further enhances the coverage effect of the buckle 120 on the groove 111a, preventing the seat belt 200 from accidentally coming off.

[0044] Furthermore, the first support arm 112 has a first connecting portion 112a at its first end in the second direction Y, and the first end of the latch 120 has a second connecting portion 121. The first connecting portion 112a and the second connecting portion 121 are rotatably connected, and the first connecting portion 112a and the second connecting portion 121 form a groove 130 that communicates with the receiving groove 111. The first connecting portion 112a is a structure provided at the end of the first support arm 112 for achieving a rotatable connection, and it can be implemented using a shaft hole, a boss, or other similar connecting structures. The second connecting portion 121 is a structure provided at the end of the latch 120 for cooperating with the first connecting portion 112a to achieve a rotatable connection, and it can be implemented using a shaft pin, a slot, or other suitable connecting structures. The groove 130 is a spatial structure formed by the first connecting portion 112a and the second connecting portion 121, so that the first connecting portion 112a and the second connecting portion 121 can deform and rotate relative to each other.

[0045] refer to Figure 2 and Figure 3 The second support arm 113 has a slot 113a on the side opposite to the receiving groove 111, and the second end of the latch 120 has a latch block 122, which engages with the slot 113a. When the latch block 122 is engaged in the slot 113a, the middle part of the latch 120 covers the groove opening 111a. When the latch block 122 is separated from the slot 113a, a channel 140 for the seat belt 200 to enter and exit is formed between the latch block 122 and the second support arm 113, and the channel 140 is connected to the groove opening 111a.

[0046] Specifically, the slot 113a is a recessed structure on the second support arm 113 for engaging with the locking block 122. It can be shaped like a rectangular slot, dovetail slot, or T-slot, providing a secure engagement point to prevent the buckle 120 from loosening under external force. The locking block 122 is a protruding structure at the second end of the buckle 120, which can be achieved through injection molding, welding, or bolting. It forms a detachable engagement with the slot 113a, ensuring reliable and flexible engagement. The channel 140 is the gap formed when the locking block 122 separates from the second support arm 113. Its width and shape can be adjusted according to the dimensions of the seat belt 200 to ensure smooth entry and exit of the receiving slot 111.

[0047] In detail, when the locking block 122 engages with the slot 113a, the middle of the buckle 120 precisely covers the opening 111a, directly blocking the exit path of the seat belt 200 and significantly enhancing its protective performance. When the seat belt 200 needs to be removed or installed, or in the event of a collision, the human body can pull the seat belt 200 to separate the locking block 122 from the slot 113a. At this time, the channel 140 formed between the locking block 122 and the second support arm 113 connects with the opening 111a, allowing the seat belt 200 to move freely in and out. This not only facilitates the removal and installation of the seat belt 200 but also releases force from the buckle 120, preventing damage to the guide ring body 110 and the generation of flying debris, thus avoiding secondary injuries.

[0048] In this embodiment, the middle part of the buckle 120 is the area between the first and second ends. Designing the middle part of the buckle 120 as an arc shape effectively disperses the pressure generated when the seat belt 200 contacts the buckle 120, avoiding localized pressure that may be caused by straight or sharp edges. This is particularly suitable for scenarios where the seat belt 200 is adjusted at large angles; the arc-shaped surface guides the seat belt 200 to slide smoothly, reducing the coefficient of friction and minimizing noise.

[0049] refer to Figure 3 and Figure 4 The guide ring body 110 also includes a fixing seat 114, which is connected to the second support arm 113. The fixing seat 114 has a mounting hole 114a. The fixing seat 114 is a structural component that provides a mounting base, and it can be made of metal plate, high-strength plastic, or composite material. The mounting hole 114a is a through hole formed in the fixing seat 114 to facilitate the overall mounting of the seat belt guide ring 100 to the external structure.

[0050] Furthermore, multiple mounting holes 114a are provided, spaced apart in the second direction Y. A positioning post 114b is correspondingly provided on the outer side of each mounting hole 114a. Specifically, the multiple mounting holes 114a are several hole structures distributed on the fixing base 114 for connecting the fastener 400, and can be implemented in various shapes such as circular, elliptical, or elongated. In practical applications, the number of mounting holes 114a can be adjusted according to actual needs, for example, it can be set to three, four, or more to meet different fixing requirements. The positioning post 114b is a protruding structure provided on the outer side of the mounting hole 114a, and can be implemented in cylindrical, square, or other adaptable shapes to provide auxiliary positioning function, accurately guiding the position of the guide ring body 110 during installation, reducing the risk of deviation, and ensuring a firm and reliable connection.

[0051] refer to Figure 4 , Figure 5 and Figure 6 This application also provides a seat, including a backrest 300, a fastener 400, and a seatbelt guide ring 100, wherein the guide ring body 110 is connected to the backrest 300 via the fastener 400. By installing the seatbelt guide ring 100 on the backrest 300, the seatbelt 200 will not come out of the seatbelt guide ring 100 when the backrest 300 is adjusted at a large angle (such as when it is flat) or when passengers of different body types are in different postures, thus ensuring the protective function of the seatbelt 200.

[0052] In this embodiment, the backrest 300 includes foam and a frame 310 disposed within the foam. The frame 310 has a positioning hole 311 and a threaded hole 312. The guide ring body 110 includes a fixing seat 114, which has a positioning post 114b and a mounting hole 114a. The positioning post 114b is inserted into the positioning hole 311, and one end of the fastener 400 passes through the mounting hole 114a and is threadedly connected to the threaded hole 312. The frame 310 is the internal support structure of the backrest 300 and can be made of high-strength steel or aluminum alloy. The positioning hole 311 is used for precise positioning, and the threaded hole 312 is used for connecting the fastener 400. Directly fixing the seatbelt guide ring 100 to the frame 310 of the backrest 300 using the fastener 400 improves the connection strength of the seatbelt guide ring 100, enhances its durability, and facilitates passenger use.
