By providing a first mounting part and a second mounting part on the guide, the first mounting part and the second mounting part are connected to the vehicle body (such as the body sheet metal), which can prevent the guiding mechanism from falling off during a collision between the vehicle body or the trolley, thereby always providing a stable guiding effect for the webbing.

[0005] The embodiments in this specification provide the following technical solutions:

[0006] This specification provides an embodiment of a seat belt webbing guide, the seat belt webbing guide comprising:

[0007] A positioning plate, wherein the positioning plate is provided with a guide opening for the seat belt webbing to pass through;

[0008] A connecting plate is disposed on one side of the positioning plate and is used for installation and connection with the vehicle body. The connecting plate has a first mounting part and a second mounting part. The first mounting part is used to cooperate with a first mating part disposed on the vehicle body. The second mounting part is used to cooperate with a second mating part disposed on the vehicle body. After the second mounting part of the connecting plate is embedded in the second mating part of the vehicle body, it can move from an initial position to an installation position relative to the vehicle body along the front-rear direction of the vehicle. The first mounting part is aligned with the first mating part only when the connecting plate is in the installation position.

[0009] The connecting plate and the positioning plate are placed on the side of the vehicle body closer to the interior. During the process of installing the connecting plate onto the vehicle body, the second mounting part is inserted into the second mating part and then moved to the installation position to achieve a snap-fit ​​connection with the vehicle body in the front-rear direction. Then, the fasteners pass through the aligned first mounting part and the first mating part respectively and are fastened to achieve a tight connection with the vehicle body.

[0010] Preferably, the second mounting part is a hook part, the hook part having a first arm extending downward from the connecting plate and away from the connecting plate and a second arm extending from the end of the first arm in the vehicle front-rear direction, and the second mating part is a rectangular hole extending in the vehicle front-rear direction;

The first arm is placed in the rectangular hole. When the connecting plate is moved to the installation position, the second arm engages with the vehicle body around the rectangular hole.

[0012] Preferably, the first arm includes an arc-shaped end and a vertical end. The arc-shaped end extends downward from the connecting plate and away from the connecting plate, and its end passes through the rectangular hole. The vertical end extends downward from the end of the arc-shaped end. The second arm extends forward from the lower end of the vertical end towards the front of the vehicle.

[0013] Preferably, when the connecting plate is in the installation position, the vertical end of the first arm and the second arm are in contact with the surface of the vehicle body away from the vehicle interior, and are engaged with the vehicle body below the rectangular hole and near the front of the vehicle.

[0014] Preferably, when the second arm extends into the second mating part and the remaining part of the connecting plate is in contact with the vehicle body surface, the rectangular hole is in contact with the inner and outer surfaces of the first arm in the vertical direction, respectively, restricting the connecting plate from moving in the vertical direction of the vehicle.

[0015] Preferably, in any embodiment of this specification, the connecting plate and the positioning plate are integral sheet metal parts. The connecting plate has a first mounting part at the center of the upper part and a hollow area symmetrically arranged along the vertical center of the first mounting part at the lower part, which communicates with the guide opening of the positioning plate. The second mounting part extends out from the top of the hollow area on the side near the rear of the vehicle.

[0016] This specification also provides a seat belt webbing guide mechanism, comprising: a guide member, wherein the guide member is the seat belt webbing guide member described in any one of the present specification; a fixing member; and a vehicle body sheet metal, wherein the vehicle body sheet metal is provided with a first mating portion and a second mating portion, the first mating portion being used to mate with a first mounting portion of the guide member, and the second mating portion being used to mate with a second mounting portion of the guide member.

[0021] By improving the design of the intermediate guide component for guiding the seat belt webbing, after the guide component is connected to the vehicle body, based on the fastening effect between the first mounting part and the vehicle body, combined with the moving mounting effect of the second mounting part along the vehicle's longitudinal direction and the limiting effect in the vehicle's vertical direction, a tight fit can be achieved under the dual functions of the first and second mounting parts. This can prevent the guide component from falling off during a collision between the vehicle body or the trolley, and can always provide a stable guiding effect for the seat belt webbing. The overall structure is simple and easy to install and use. Attached Figure Description

[0034] It should also be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of this application. The drawings only show the components related to this application and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0035] Additionally, specific details are provided in the following description to facilitate a thorough understanding of the examples. However, those skilled in the art will understand that practice can be carried out without these specific details.

[0036] In the existing design, the installation between the guide component and the vehicle body is prone to causing the guide component to detach under the force of the webbing, which may pose a safety hazard to the occupants.

[0037] After in-depth analysis and improvement exploration of the structure, installation method, and force exerted on the guide component by the webbing, a seat belt webbing guide component solution is proposed. Through structural and installation improvements, it can effectively prevent detachment and thus provide stable and reliable guidance for the webbing to ensure occupant safety.

[0038] like Figures 1 to 3 As shown, the guide 3 includes a positioning plate 32 and a connecting plate 31.

[0039] The positioning plate 32 is provided with a guide opening 321 for the seat belt webbing 1 to pass through. In actual use, the guide opening 321 allows the webbing to pass through in the vertical direction and causes the webbing 1 to deviate towards the inside of the vehicle and towards the side of the vehicle body. Therefore, the guide opening 321 plays a good role in positioning and restraining the webbing.

[0040] The connecting plate 31 is disposed on one side of the positioning plate 32 and is used to install and connect with the vehicle body 4 (here, a partial position of the installation guide is shown, such as the body sheet metal). The connecting plate 31 is provided with a first mounting part 311 and a second mounting part 312. The first mounting part 311 is used to cooperate and connect with a first mating part 41 disposed on the vehicle body 4, and the second mounting part 312 is used to cooperate and connect with a second mating part 42 disposed on the vehicle body 4. After the second mounting part 312 of the connecting plate 31 is embedded into the second mating part 42 of the vehicle body 4, it can move from the initial position to the installation position relative to the vehicle body 4 in the front-rear direction of the vehicle. The first mounting part 311 is fixedly connected only when the connecting plate 31 is in the installation position after being aligned with the first mating part 41.

[0041] like Figure 2 As shown, during the process of installing the guide 3 (actually the connecting plate 31 part in the guide) onto the vehicle body, the second mounting part 312 is inserted into the second mating part 42 and then moved to the installation position to achieve a snap-fit ​​connection with the vehicle body in the front and rear directions. Then, the fixing part 2 passes through the aligned first mounting part 311 and the first mating part 41 respectively and is tightened to achieve a tight connection between the guide 3 and the vehicle body 4.

[0042] like Figure 3 As shown, after installation, the guide 3 (i.e., the whole of the connecting plate 31 and the positioning plate 32) is placed on the side of the vehicle body closer to the interior. The webbing 1 passes through the guide 3 (i.e., the guide opening 321) in the vertical direction, causing the webbing 1 to deviate towards the side closer to the vehicle body. The guide 3 effectively positions and constrains the webbing 1.

[0043] In actual use, during a collision with the vehicle body or trolley, the webbing is subjected to force, causing it to pull out rapidly. There are forward and inward forces on the webbing, which can cause the guide component 3 to tend to detach. However, if... Figures 4 to 5As shown, after the guide member 3 is fixed to the vehicle body 4 by the fastener 2, there is a force between the first mounting part 311 of the guide member 3, the fastener 2 and the vehicle body 4. Even if there is deformation after being subjected to force, under the interlocking action between the second mounting part 312 of the guide member 3 and the vehicle body 4, the guide member 3 as a whole can be subjected to the dual action between the first mounting part 311 and the second mounting part 312 and the vehicle body 4. Therefore, the guide member 3 and the vehicle body 4 can fit tightly together, effectively preventing the guide member 3 from falling off the vehicle body 4. Thus, the guide member 3 can stably and reliably provide positioning and restraint for the webbing 1, which can ensure the safety of the occupants.

[0044] In some implementations, such as Figures 1 to 5 As shown, the second mounting portion 312 can be configured as a hook portion, which has a first arm 3121 extending downward from the connecting plate 31 and away from the connecting plate, and a second arm 3122 extending from the end of the first arm towards the front of the vehicle. The second mating portion 42 is configured as a rectangular hole extending along the front-rear direction of the vehicle. During the process of installing the connecting plate 31 as a whole onto the vehicle body 4, the second arm 3122 extends from the side of the vehicle body 4 closest to the interior through the rectangular hole to the side of the vehicle body away from the interior. The first arm 3121 is placed in the rectangular hole, and when the connecting plate 31 as a whole is moved from the initial position to the mounting position, the second arm 3122 engages with the vehicle body around the rectangular hole.

[0045] In some implementations, such as Figures 5 to 8 As shown, the first arm 3121 includes an arc-shaped end 31211 and a vertical end 31212. The arc-shaped end 31211 extends downward from the connecting plate 31 and away from the connecting plate 31, and its end passes through the rectangular hole. The vertical end 31212 extends downward from the end of the arc-shaped end 31211. The second arm 3122 extends forward from the lower end of the vertical end 31212 towards the front of the vehicle to better engage with the vehicle body 4 and better prevent the guide 3 from detaching from the vehicle body 4.

[0046] In some embodiments, when the connecting plate 31 is in the installation position, the vertical end 31212 of the first arm 3121 and the second arm 3122 are in contact with the side surface of the vehicle body away from the vehicle interior, and are engaged with the vehicle body below the rectangular hole near the front end of the vehicle and in the direction of the front of the vehicle.

[0047] It should be noted that this snap-fit ​​connection method makes the connection between the connecting plate and the vehicle body more stable and reliable. When subjected to a frontal or oblique impact from the vehicle, the connecting plate tends to move forward relative to the vehicle body. This increases the contact strength between the first arm of the second mounting part and the end of the rectangular hole near the front of the vehicle, thus strengthening the snap-fit ​​structure. Even under high-energy impacts with significant deformation of the vehicle body, the snap-fit ​​connection remains intact. Furthermore, the vertical end of the first arm and the second arm are in contact with the surface of the vehicle body, maintaining a certain interference force in the installation position. This allows the frictional force to further maintain the position of the connecting plate on the vehicle body during the aforementioned impact. When subjected to the impact component from the side of the vehicle, this close contact further increases the frictional force, making the connecting plate less likely to detach from the vehicle body.

[0048] In some embodiments, when the second arm 3122 extends into the second mating part 42 and the remaining part of the connecting plate 31 is in contact with the vehicle body surface, the rectangular hole is in contact with the inner and outer surfaces of the first arm in the vertical direction, respectively, restricting the movement of the connecting plate 31 in the vertical direction of the vehicle, further reducing the possibility of the guide 3 detaching from the vehicle body 4, and making the guide 3 more securely attached to the vehicle body 4.

[0049] In some implementations, such as Figure 3 As shown, the included angle between the connecting plate 31 and the positioning plate 32 is greater than or equal to 90°, so as to better position and constrain the webbing 1.

[0050] In some embodiments, the connecting plate 31 and the positioning plate 32 are integral sheet metal parts, and the connecting plate 31 has a first mounting part 311 at the upper center position and a hollow area symmetrically arranged along the vertical center of the first mounting part 311 at the lower part (see [reference]). Figure 1 , Figure 2 , Figure 4 or Figure 6 (as shown in the diagram), the hollowed-out area is configured to communicate with the guide opening 321 of the positioning plate 32, and the second mounting part 312 extends from the top of the hollowed-out area on the side near the rear of the vehicle. At this time, the guide 3 not only has a simple structure and is easy to process and manufacture, but is also lightweight and has good structural strength, which better prevents the guide 3 from falling off under the action of the webbing 1.

[0051] Based on the same inventive concept, such as Figures 1 to 8 As shown, this specification also provides a seat belt webbing guide mechanism, including: a guide member 3, which is the seat belt webbing guide member described in any of the foregoing embodiments of this specification; a fixing member 2; and a vehicle body sheet metal, wherein the vehicle body sheet metal is provided with a first mating part and a second mating part, the first mating part being used to mate with a first mounting part of the guide member, and the second mating part being used to mate with a second mounting part of the guide member.

[0052] It should be noted that the body sheet metal here can be the body 4 shown in the aforementioned embodiments. Therefore, the first mating part and the second mating part on the body sheet metal can respectively correspond to the first mating part 41 and the second mating part 42 in the aforementioned embodiments, and will not be distinguished below.

[0053] In some embodiments, the first mating part and the first mounting part can be configured as round holes, and the fastener 2 is preferably a plastic screw, which not only meets the installation and use requirements between the guide 3 and the vehicle body 4, but also simplifies the structural design and facilitates installation and use.

[0054] In some embodiments, the centers of the first mating portion 41 and the second mating portion 42 do not coincide. For example... Figure 2 As shown, the first mating part 41 is located on the vertical line of the end of the second mating part 42 near the front of the vehicle. After the second mounting part 312 of the guide member 3 passes through the second mating part, it can not only move along the front of the vehicle to move the connecting plate 31 to the installation position for fixed installation, but also prevent the connecting plate 31 from detaching from the vehicle body 4 under the dual effect of the connection between the first mounting part 311 and the second mounting part 312 of the connecting plate 31 and the first mating part 41 and the second mating part 42 of the vehicle body 4.

[0055] It should be noted that since the ends of the first mating part 41 and the second mating part 42 near the front of the vehicle are on the same vertical line, the fixed position of the first mounting part 311 and the snap-fit ​​position of the second mounting part 312 are also on the same vertical line. When the vehicle is impacted, the connecting plate 31 mounted on the vehicle body is prevented from unnecessary self-rotation or rotational tendency, and always maintains a translational tendency. More preferably, the center of gravity of the connecting plate 31 is located on this vertical line, which is even more conducive to preventing the connecting plate from rotating.

[0056] Based on the same inventive concept, this specification also provides a vehicle that may include the seat belt webbing guide as described in any of the foregoing embodiments, or the seat belt webbing guide mechanism as described in any of the foregoing embodiments, to provide stable and reliable positioning guidance and constraint for the seat belt webbing through the guide or guide mechanism.

[0057] The various embodiments in this specification are described in a progressive manner. Similar or identical parts between embodiments can be referred to interchangeably. Each embodiment focuses on describing the differences from other embodiments. In particular, the product embodiments described later are relatively simple since they correspond to the methods; relevant parts can be referred to the descriptions in the system embodiments.

[0058] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
