[0002] A seatbelt height adjustment lock is a device used in automotive seatbelt systems. Its main function is to allow users to adjust the height of the seatbelt according to their height and seating position, and lock it after it is adjusted to a suitable position to ensure that the seatbelt can properly restrain the passenger and improve driving safety.

[0003] Currently available seatbelt height adjustment locks have certain limitations in actual use, especially in terms of multi-level adjustment function. This design flaw makes it inconvenient for users of different heights to adjust the seatbelt height, making it difficult to meet diverse adjustment needs and thus affecting the comfort of wearing the seatbelt.

[0004] For shorter users, existing seatbelt height adjustment locks may not be able to adjust the seatbelt to a low enough position, resulting in the shoulder strap being too high, compressing the neck, and causing discomfort. For taller users, the seatbelt may not be able to be adjusted to a high enough position, and the shoulder strap may slip down onto the arm, failing to effectively restrain the body and reducing the protective effect of the seatbelt. In addition, even users of similar height may need to make minor adjustments to the seatbelt height due to different sitting postures and seat positions, but existing single-level or limited-level adjustment designs cannot meet this personalized need.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0032] Please see Figures 1-3 In this embodiment of the present invention, a seatbelt height adjustment lock includes a B-pillar protective shell 1 and a sliding plate 2 sliding on the B-pillar protective shell 1. The sliding plate 2 is characterized by having a stepless locking structure that abuts against the B-pillar protective shell 1. The stepless locking structure includes:

[0033] An adjusting seat 3 is provided on the sliding plate 2 and slides on the B-pillar protective shell 1. An adjusting component that is inserted into the sliding plate 2 is slidably connected to the adjusting seat 3.

[0034] Two fixing members are provided on both sides of the sliding plate 2 and two limiting pins 14 are rotated on the fixing members. A spring-loaded member is provided between the two limiting pins 14 to maintain the distance between them. The limiting pins 14 are configured to abut against the B-pillar protective shell 1 for height locking. The limiting pins 14 are configured to abut against the adjusting member for adjusting the height locking state.

[0035] In this embodiment, the adjustment seat 3 is disposed on the sliding plate 2 and can slide smoothly within the B-pillar protective shell 1. The adjustment component is connected to the sliding plate 2 by a plug-in connection and slides on the adjustment seat 3, so that the user can easily change the position of the sliding plate 2 by operating the adjustment component when adjusting the seat belt height.

[0036] Meanwhile, two fixing parts are respectively set on both sides of the sliding plate 2, providing a stable support point for the limiting pin 14. The limiting pin 14 is rotatably connected to the fixing parts and can abut against the B-pillar protective shell 1 during the adjustment process, thereby achieving the height locking function. The key to this design is the spring-loaded part set between the two limiting pins 14, which can effectively maintain the distance between the two and ensure that the limiting pin 14 can flexibly contact or separate from the B-pillar protective shell 1 and the adjusting part during the adjustment process, thereby achieving precise height locking at different positions.

[0037] When a user needs to adjust the seat belt height, they simply pull the adjusting piece, causing the sliding plate 2 to slide up and down inside the B-pillar protective shell 1. When the sliding plate 2 moves to the appropriate position, the limiting pin 14 will abut against the B-pillar protective shell 1 under the action of the spring-loaded part, ensuring that the seat belt height is firmly locked. This stepless adjustment method can not only meet the personalized needs of different users for seat belt height, but also greatly improve the convenience and comfort during use.

[0038] Please see Figure 1 and Figure 2 As a further embodiment of this utility model, two limiting strips 6 are symmetrically fixed on the B-pillar protective shell 1, and anti-slip textures are evenly distributed on the two limiting strips 6.

[0039] In this embodiment, two limiting strips 6 are symmetrically fixed on the B-pillar protective shell 1. These two limiting strips 6 not only provide a stable sliding track for the sliding plate 2, but also enhance the friction between the sliding plate 2 and the limiting pin 14 through their evenly distributed anti-slip texture, thereby ensuring that the sliding plate 2 can move more smoothly and accurately during the adjustment process.

[0040] Please see Figure 3 and Figure 4 As a further embodiment of this utility model, the adjusting seat 3 is provided with a sliding groove 4, and a buckle 5 is rotatably installed on the adjusting seat 3.

[0041] In this embodiment, the adjusting seat 3 is provided with a sliding groove 4. This structure provides a precise sliding path for the adjusting component, ensuring that it can move smoothly and steadily during the adjustment process. The design of the sliding groove 4 not only optimizes the continuity of the adjustment action, but also provides a clear guide for the positioning of the adjusting component, so that the user can more accurately control the position of the sliding plate 2 when adjusting the seat belt height.

[0042] Please see Figure 3 and Figure 5 As a further embodiment of this utility model, the adjusting component includes a pull seat 7 that slides in the sliding groove 4, a plug post 9 disposed on the pull seat 7, a first spring 10 sleeved on the plug post 9, and an abutment plate 11 fixedly installed with the plug post 9.

[0043] Limiting blocks 8 are fixed on both sides of the pull seat 7. The limiting blocks 8 slide in the corresponding slots opened at the sliding groove 4. One end of the first spring 10 abuts against the contact plate 11, and the other end abuts against the sliding plate 2.

[0044] In this embodiment, the pull seat 7 is the core component of the adjustment mechanism. It slides within the sliding groove 4, providing a direct operating interface for the user. Limiting blocks 8 are fixed on both sides of the pull seat 7. These limiting blocks 8 slide within the corresponding slots in the sliding groove 4. This design not only provides a stable sliding path for the pull seat 7, but also limits the range of movement of the pull seat 7 through the cooperation of the limiting blocks 8 and the slots, preventing it from deviating or leaving the track during the adjustment process, thereby ensuring the smoothness and accuracy of the adjustment process.

[0045] The plug post 9 is mounted on the pull seat 7 and passes through the sliding plate 2. A first spring 10 is sleeved on the plug post 9. One end of the spring abuts against the contact plate 11 and the other end abuts against the sliding plate 2. This structure provides the adjustment component with an elastic reset function. When the user releases the pull seat 7, the first spring 10 can automatically restore the pull seat 7 to the initial position, ensuring that the adjustment component remains stable in the non-operational state, and at the same time preparing for the next adjustment.

[0046] The contact plate 11 is fixedly installed at the end of the plug post 9. It abuts against the first spring 10 and plays the role of transmitting the spring force. At the same time, the contact plate 11 also interacts with the limit pin 14. When the pull seat 7 moves, the contact plate 11 can push the limit pin 14 into the unlocked state, thereby adjusting the sliding plate 2. This design not only realizes stepless height adjustment, but also ensures the reliability and stability of locking through the ingenious cooperation of the mechanical structure.

[0047] Please see Figure 6 and Figure 7 As a further embodiment of this utility model, the fixing member includes a fixing seat 12 disposed on the sliding plate 2 and a rotating pin 13 disposed on the fixing seat 12 for rotatably connecting to the limiting pin 14.

[0048] One end of the limiting pin 14 is provided with a rotating groove 15, and the other end of the limiting pin 14 is provided with a contact surface 16 that abuts against the limiting strip 6.

[0049] In this embodiment, the fixing component consists of a fixing seat 12 and a rotating pin 13. The fixing seat 12 is firmly installed on the sliding plate 2, providing a solid support foundation for the entire locking structure. The rotating pin 13 is set on the fixing seat 12, and its main function is to provide a stable rotating connection point for the limit pin 14, ensuring that the limit pin 14 can rotate flexibly during the adjustment process, thereby realizing the locking and unlocking functions.

[0050] The limiting pin 14 has a rotating groove 15 at one end. This structural design allows the limiting pin 14 to be tightly engaged with the rotating pin 13 through the rotating groove 15, achieving a smooth rotation action. This rotating connection method ensures the flexibility of the limiting pin 14 during operation.

[0051] The other end of the limiting pin 14 is provided with an abutting surface 16, which abuts tightly against the limiting strip 6. When the sliding plate 2 slides up and down inside the B-pillar protective shell 1, the abutting surface 16 of the limiting pin 14 will interact with the anti-slip texture on the limiting strip 6, thereby achieving gradual adjustment and locking of the height.

[0052] In actual use, when the user adjusts the height of the seat belt using the adjusting component, the limiting pin 14 will rotate flexibly under the support of the rotating pin 13. Its contact surface 16 interacts with the anti-slip texture of the limiting strip 6 to achieve gradual height adjustment. When the appropriate position is reached, the limiting pin 14 will automatically abut against the limiting strip 6 under the action of the spring-loaded component to lock it in place, thus firmly setting the sliding plate 2 in that position.

[0053] Please see Figure 6 and Figure 8 As a further embodiment of this utility model, the spring-loaded component includes two rotating shafts 18 rotating at the rotating groove 15, a rotating column 17 disposed on the rotating shafts 18, and a second spring 19 disposed between the two rotating columns 17.

[0054] The rotating column 17 has a corresponding insertion hole at its end that mates with the second spring 19.

[0055] In this embodiment, the spring-loaded component consists of two rotating shafts 18, two rotating columns 17, and a second spring 19. The rotating shafts 18 are installed in the rotating groove 15 of the limiting pin 14, providing stable rotational support for the rotating columns 17. The rotating columns 17 are mounted on the rotating shafts 18 and can rotate within the rotating groove 15 via the rotating shafts 18.

[0056] The second spring 19 is the core component of the rebound mechanism. It is located between the two rotating columns 17 and provides elastic support for the limit pin 14. When the limit pin 14 rotates during the adjustment process, the second spring 19 can generate elastic deformation, thereby providing a restoring force for the limit pin 14. This design allows the limit pin 14 to automatically reset after the adjustment is completed, ensuring that it always maintains good contact with the limit bar 6, thereby achieving a stable height locking function.

[0057] In order to better match the elastic action of the second spring 19, the rotating column 17 is provided with a hole at the end corresponding to the second spring 19. This design not only provides a stable installation position for the second spring 19, but also ensures that the spring can apply force evenly during operation, thereby improving the working efficiency and reliability of the entire spring return component.

[0058] In practical use, when the user adjusts the seat belt height using the adjusting mechanism, the limiting pin 14 rotates flexibly under the support of the rotating shaft 18 and the rotating column 17. At this time, the second spring 19 will generate corresponding elastic deformation according to the rotation angle of the limiting pin 14, providing a restoring force for the limiting pin 14. When the user releases the adjusting mechanism, the elastic force of the second spring 19 will automatically push the limiting pin 14 back to its original position, causing it to re-abut against the limiting strip 6, thereby firmly setting the sliding plate 2 at the adjusted height position. This spring-loaded design not only improves the adjustment flexibility and locking stability of the seat belt height adjusting lock, but also achieves a stepless locking effect. Through the elastic action of the second spring 19, the limiting pin 14 can always maintain good contact with the limiting strip 6 during the adjustment process, ensuring accurate locking of the seat belt height, and also providing users with a more convenient and reliable user experience.

[0059] A seat belt includes a seat belt body 20, specifically, the seat belt body 20 is mounted on the buckle 5.

[0060] The above embodiments are exemplary and not restrictive. Therefore, without departing from the spirit or basic characteristics of this utility model, any technical solutions that can be implemented in other specific forms are included in this utility model.
