[0017] Example: See Figure 1 , 2 As shown, a mounting bracket for a car seat belt includes a horizontal base plate 1 in the shape of a right-angled trapezoid. An upwardly inclined belt outlet plate 11 is formed on the right side of the base plate 1. A horizontal connecting plate 12 is formed on the right side of the belt outlet plate 11. A rectangular belt-passing slot 13 is formed on the left side of the belt outlet plate 11, and a rectangular guide slot 14 connected to the belt-passing slot 13 is formed on the right side. A guide rolled edge 15 with a circular arc cross-section is formed on the right side of the guide slot 14, and the guide rolled edge 15 is located within the guide slot 14. An arc-shaped opening 16 is formed in the middle of the guide rolled edge 15. Vertical baffles 17 are bent at the front and rear ends of the opening 16, respectively. The baffles 17 are located inside the guide rolled edge 15 and abut against the front and rear ends of a longitudinal roller 2, which is inserted into the guide rolled edge 15.

[0018] The front and rear ends of the roller 2 are located on the front and rear sides of the through-slot 13, respectively, and the front and rear sides of the through-slot 13 are respectively bent into downward arc-shaped side curls 18.

[0019] The base plate 1 is formed with a plurality of connecting slots 112, such as Figure 2 As shown, the connecting slot 112 consists of a trapezoidal clearance slot on the left and a rectangular buckle slot on the right. The buckle at the bottom of the seat belt retractor can be snapped into the buckle slot of the base plate 1. At the same time, some components at the bottom of the seat belt retractor are set in the clearance slot, so that the base plate 1 fits against the bottom of the seat belt retractor. Meanwhile, the front and rear sides of the base plate 1 and the front and rear sides of the connecting plate 12 are respectively formed with a number of mounting slots 111. The mounting slots 111 on the base plate 1 are of the waist-shaped hole structure. Screws can be installed in the mounting slots 111 of the base plate 1. The base plate 1 can be fixedly connected to the mounting part of the seat belt retractor on the vehicle by the screws. At the same time, screws are inserted into the mounting slots 111 of the connecting plate 12, and the screws are fixedly connected to the seat belt retractor. This facilitates the installation and connection of the seat belt retractor on the vehicle.

[0020] The length of the strip slot 13 on the strip plate 11 is less than the length of the guide slot 14. The front and rear ends of the guide rolled edge 15 and the front and rear sides of the guide slot 14 are left with gaps. The guide rolled edge 15 is processed by the remaining edge plate after the plate is stamped and cut. The rolled edge processing of the guide rolled edge 15 requires the above-mentioned gaps.

[0021] The diameter of the inner wall of the guide crimp 15 is equal to the diameter of the outer wall of the roller 2. The length of the roller 2 is less than the length of the guide crimp 15. The roller 2 can roll inside the guide crimp 15, but the guide crimp 15 cannot move radially.

[0022] The arc radius of the guide crimp 15 is greater than π, and the arc radius of the opening 16 on the guide crimp 15 is less than π. The above-mentioned size limitation is to prevent the roller 2 from detaching from the guide crimp 15.

[0023] The left side of the belt slot 13 on the belt outlet plate 11 is bent into a downward arc-shaped left rolled edge 19. The left rolled edge 19 can reduce the wear between the seat belt and the left side of the belt slot 13 during the process of the seat belt retracting into the rewinder.

[0024] The left side of the seat belt slot 13 has notches 110 extending forward and backward respectively at the front and rear ends. The front and rear ends of the left rolled edge 19 extend to the notches 110 respectively. The notches 110 can extend the length of the left rolled edge 19, so that the front and rear ends of the left rolled edge 19 are located at the front and rear sides of the side rolled edge 18. Thus, the side rolled edge 18 can prevent the seat belt from contacting the front and rear ends of the left rolled edge 19.

[0025] Working principle: This structure is a mounting bracket for car seat belts. Its technology is mainly reflected in the side structure on the side of the belt slot 13. The side is provided with a guide roll 15, and a roller 2 can be installed in the guide roll 15. At the same time, the guide roll 15 has rollers 2 that come into contact with the rollers 2. Thus, when the seat belt is pulled out, it mainly abuts against the rollers 2, and the rollers 2 will roll. The friction is small, so the seat belt is not easy to wear.

[0026] The embodiments described above are illustrative of the present invention and are not intended to limit the present invention. Any person skilled in the art can modify the embodiments without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be as set forth in the claims.
