[0050] During use, the entire seat belt guiding module is fixedly installed on the backrest 4 of the vehicle seat through the fixing seat 3. The support rod 12 is inserted into the fixing seat 3. When it is necessary to adjust the position of the seat belt guiding seat assembly 2 up and down, a force is applied to the support rod 12 to overcome the elastic force of the two second engaging members 30. The support rod 12 squeezes the two second engaging members 30 to deform them, and switches to engage with other second gear slots 120. After adjustment, the two second engaging members 30 are snapped into the second gear slots 120 to ensure the reliable up and down position of the support rod 12, and further ensure the reliable up and down position of the seat belt guiding seat assembly 2. When it is necessary to adjust the position of the seat belt guiding seat assembly 2 left and right, a force is applied to the seat belt guiding seat 21 to overcome the elastic force of the two first engaging members 22. The two first engaging members 22 deform and disengage from the original first gear slot 111 and snap into other first gear slots 111. After adjusting the left and right positions, the two first engaging members 22 are snapped into the first gear slots 111 on both sides of the sliding slot 110 to ensure the reliable left and right position of the seat belt guiding seat assembly 2.

[0051] In this solution, the mounting body 1 is provided with a sliding slot 110 and a plurality of first gear slots 111. The seat belt guiding seat assembly 2 is slidably arranged in the sliding slot 110, and can realize two-way adjustment in the left and right directions. And by engaging the first engaging member 22 in the first gear slot 111, the position limitation after two-way adjustment in the left and right positions can be realized. Further, the support rod 12 in the mounting body 1 is arranged in the fixing seat 3 in a liftable and adjustable manner, and can realize two-way adjustment in the up and down directions. And by engaging the plurality of second gear slots 120 provided on the support rod 12 with the second engaging members 30 on the fixing seat 3, the position limitation after the up and down position adjustment can be realized. That is, it is ensured that the seat belt is adjustable in four directions, which can meet the use requirements of passengers of different body types, and can effectively ensure good comfort. The entire seat belt guiding module is installed on the backrest 4 of the vehicle seat and moves with the movement of the backrest 4 for integrated adjustment, which is convenient for passengers to use in different usage scenarios (such as zero-gravity mode and designed position mode, etc.). And the overall weight of the seat belt guiding module is light and the cost is low.
