The slide rail 1 includes an adjustment portion 11 and mounting portions 12 at both ends. Mounting holes 121 are provided in the mounting portions 12. The height adjustment bracket can be fixedly connected to the upper end of the B-pillar by installing fastening bolts through the mounting holes 121. An adjustment groove 111 is provided in the adjustment portion 11, and the adjustment block 2 is slidably installed in the adjustment groove 111. The adjustment block 2 further includes a sliding plate 24. Sliding grooves 13 are provided on both sides of the bottom of the adjustment groove 111, and the sliding plate 24 is slidably connected through the sliding grooves 13. Sliding blocks 241 are provided on both sides of the sliding plate 24, and the sliding blocks 241 are slidably matched with the sliding grooves 13.

[0029] First matching portions 112 are provided on both sides of the adjustment portion 11, and second matching portions 212 are provided on both sides of the connecting plate 21. The first matching portions 112 are matched with the second matching portions 212. Specifically, the second matching portions 212 are stuck on the first matching portions 112, so that while the connecting plate 21 is slidably connected to the adjustment portion 11, the connecting plate 21 can be prevented from falling off during sliding.

[0030] An elastic telescopic rod 23 is provided between the sliding plate 24 and the connecting plate 21. Correspondingly, a first matching tooth 14 is provided below the first matching portion 112, and a second matching tooth 22 is provided above the second matching portion 212. The first matching tooth 14 is matched with the second matching tooth 22. Specifically, the first matching tooth 14 and the second matching tooth 22 are meshed with each other in an alternating manner.

[0031] In this embodiment, the longitudinal sections of the first matching tooth 14 and the second matching tooth 22 are rectangular ( Figure 7 ), but in other embodiments of the present invention, the longitudinal sections of the first matching tooth 14 and the second matching tooth 22 can also be triangular, trapezoidal and other shapes. For those skilled in the art, any tooth shape that can achieve stable cooperation between the first matching tooth 14 and the second matching tooth 22 should fall within the protection scope of the present invention.

[0032] A sleeve 231 and a connecting rod 232 are provided in the elastic telescopic rod 23. The connecting rod 232 is sleeved in the sleeve 231. The sleeve 231 and the connecting rod 232 are slidably sleeved with limited positions. A limit stop 2311 is provided at the front end (the actual position is horizontally forward, and Figure 7 is the upper end in the attachment) of the sleeve 231, and a limit ring 2321 is provided at the end of the connecting rod 232. The limit stop 2311 is matched with the limit ring 2321, and a spring 233 is provided between the end of the connecting rod 232 and the inner end of the sleeve 231.

[0033] The principle of the present invention is:

[0034] When the utility model is installed, the retractor of the safety belt is fixedly installed below the B-pillar, the height adjustment bracket is installed above the B-pillar, and then the slip ring 3 of the safety belt is installed with the height adjustment bracket.

[0035] When in use, the utility model can realize the adjustment of the safety belt at any height position; specifically, when the height of the safety belt needs to be adjusted, the adjustment block 2 is pressed through the slip ring 3. At this time, the first mating tooth 14 and the second mating tooth 22 are separated from each other. Then, the position of the adjustment block 2 can be freely moved. After adjusting to the appropriate position, stop applying force. Then, under the action of the elastic telescopic rod 23, the adjustment block 2 rebounds. At this time, the first mating tooth 14 and the second mating tooth 22 are re-mated, realizing the fixation of the position of the adjustment block 2.

[0036] It should be noted in the above process that in the accompanying drawings of the embodiment, the first mating tooth 14 and the second mating tooth 22 are rectangular. Therefore, after stopping applying force to the adjustment block 2, the first mating tooth 14 and the second mating tooth 22 may not be re-mated. At this time, only need to gently pull the safety belt, and the safety belt drives the adjustment block 2 to have a small displacement. When the adjustment block 2 rebounds significantly and there is an obvious mating sound, it means that the second mating tooth 22 and the second mating tooth 22 are completed in mating. At this time, pulling the safety belt, the adjustment block 2 will be stuck and will not move; thus, the adjustment of the fixed height of the upper end of the safety belt is realized, so that people with different physiques can wear the safety belt safely and effectively.

[0037] It should also be noted that the mating situation of the above first mating tooth 14 and the second mating tooth 22 can also be improved by adjusting the tooth shape of the mating teeth. However, there is no doubt that the rectangular mating method is a more safe and stable mating method. Therefore, in the utility model, the rectangular mating method is taken as a more preferred option.
