[0023] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0024] Reference Figure 1 This embodiment includes a seat belt bracket 1 and a fixed base 2. One end of the seat belt bracket 1 is provided with a universal ball 13, and one end of the fixed base 2 has a ball head groove 21. The universal ball 13 is installed in the ball head groove 21 to form a ball head joint bearing structure, so that the seat belt bracket 1 can move freely within a certain range, and at the same time, the seat belt bracket 1 can rotate to the shoulder side of the passenger. In addition, the position of the seat belt bracket 1 is usually fixed on the side close to the seat belt.
[0025] Reference Figure 1 , Figure 2 and Figure 3In embodiment 1, when the fixed position of the fixed base 2 is the headrest sleeve rod on the seat, the fixed base 2 includes a fixed platform 22 and a fixed pin 23. The fixed platform 22 has a pin groove 221, a headrest insertion hole 222, and an opening groove 223. Both the opening groove 223 and the pin groove 221 are arranged along the length direction of the fixed platform 22. The opening groove 223 penetrates the fixed platform 22 from top to bottom. There are two pin grooves 221, which are symmetrically distributed on both sides of the opening groove 223. The openings of the headrest and the opening slot 223 are located on the same side. Two headrest insertion holes 222 are provided and communicate with the opening slot 223. The center line connecting the two headrest insertion holes 222 coincides with the axis of the opening slot 223. The fixing pin 23 has two needle tips, each corresponding to a needle groove 221. The fixing pin 23 is removed, and the opening slot 223 on the fixing platform 22 is slightly pried open to allow the headrest sleeve to fit into the headrest insertion hole 222. Then, the fixing pin 23 is inserted back into the needle groove 221 to complete the installation. In another embodiment, the fixing base 2 only includes the fixing platform 22, and the fixing platform 22 also only has headrest insertion holes 222. Installation is achieved by removing the headrest and inserting the sleeve into the headrest insertion hole 222.
[0026] Reference Figure 4 In embodiment 2, when the fixed base 2 is fixed at the B-pillar, the fixed base 2 includes a fixed plate 24, an elastic band 25, a fixing clip 26, and a fixing rod 27. One end of the elastic band 25 is connected to the fixed plate 24, and the other end is connected to the fixing clip 26. The fixing rod 27 is fixedly installed on the fixed plate 24. At this time, the ball head groove 21 is set at the end of the fixing rod 27. The fixing clip 26 at the end of the elastic band 25 is inserted into the inner gap of the sealing strip on both sides of the B-pillar of the car seat belt outlet to achieve fixation. The seal between the B-pillar and the car door is achieved by the sealing strip on the B-pillar. The sealing strip is stuck on the metal protrusion of the B-pillar. There is a tight gap between the inner side of the sealing strip and the B-pillar decorative panel. The metal clip can be inserted to fix the device.
[0027] Reference Figure 5 In embodiment 3, the fixed base 2 is fixedly installed on the seat or B-pillar of the car; when the fixed position of the fixed base 2 is the seat, the fixed base 2 is the fixed rod 27, which is inserted vertically into the seat above the side of the car door. The seat belt bracket 1 is swung so that it is perpendicular to the seat, that is, the orientation of the seat belt bracket 1 is the front and rear direction of the car. Figure 5 The diagram shows the installation position for the driver's seat. In actual use, the seat belt bracket 1 needs to be rotated so that it faces forward, so that the seat belt can be placed on the seat belt bracket 1.
[0028] Reference Figure 6In embodiment 4, when the fixed position of the fixed base 2 is the headrest on the seat, the fixed base 2 is the fixed rod 27, which is vertically inserted into the side of the headrest near the car door. Figure 6 This is an illustration of the installation in the front passenger seat. In actual use, the seat belt bracket 1 needs to be rotated so that it faces forward, so that the seat belt can be placed on the seat belt bracket 1.
[0029] Reference Figure 1 and Figure 4 The seat belt bracket 1 includes a bracket platform 11 and a connecting rod 12, with a universal ball 13 mounted on the connecting rod 12. There are two ways to connect the bracket platform 11 and the connecting rod 12: one is a telescopic sliding method, and the other is a fixed method.
[0030] Reference Figure 1 , Figure 2 and Figure 3 In the telescopic sliding mode, the connecting rod 12 has a telescopic hole 121, and a telescopic rod 111 is provided at the bottom of the bracket platform 11. The telescopic rod 111 is slidably connected to the telescopic hole 121. Simultaneously, the end of the outer circumferential surface of the connecting rod 12 away from the universal ball 13 has a thread, and the outer circumferential surface of the connecting rod 12 has multiple vertical grooves 122 communicating with the telescopic hole 121. The vertical grooves 122 are evenly distributed around the axis of the connecting rod 12. The threaded end of the connecting rod 12 has a locking slope 123 that faces the bracket platform 11 and is inclined towards the axis of the connecting rod 12. Furthermore, a fastening cap 14 is provided on the connecting rod 12. The fastening cap 14 has an internal thread and is threadedly connected to the connecting rod 12. The interior of the fastening cap 14 has a fastening slope 141 with the same inclination direction as the locking slope 123. Insert the telescopic rod 111 at the bottom of the bracket platform 11 into the telescopic hole 121. Before this, the fastening cap 14 has been placed at the end of the connecting rod 12. After telescopically extending to the appropriate position, rotate the fastening cap 14. With the engagement of the threads, the fastening inclined surface 141 moves closer to the locking inclined surface 123 until it abuts. Under the action of the gap in the vertical groove 122, the threaded part of the connecting rod 12 will retract inward and thus abut against the telescopic rod 111 to achieve fixation. In the fixing method, the connecting rod 12 is connected to the bottom of the bracket platform 11 as a whole, and the connecting rod 12 is a flexible deformable rod, so that the seat belt bracket 1 can be repeatedly and arbitrarily adjusted in a certain direction. That is, the height of the seat belt bracket 1 can be adjusted by the telescopic rod 111 or the flexible deformable rod, and the direction of the seat belt bracket 1 can be adjusted by the universal ball 13.
[0031] Furthermore, the height of the seatbelt bracket 1 is generally at least 1 cm higher than the occupant's shoulder plane (when the seatbelt is fastened and tightened, the narrowest point between the seatbelt and the shoulder should not exceed the thickness of one finger). When the seatbelt is fastened and tightened, placing it on the seatbelt bracket 1 ensures that the seatbelt does not contact the occupant's shoulder or adjacent neck area, preventing pressure and discomfort in these areas. This increases the occupant's willingness to use the seatbelt and prevents them from feeling pressure on their shoulders and neck. It also prevents the seatbelt from being caught or held in place by the occupant, ensuring seatbelt effectiveness and eliminating safety hazards caused by improper use. The attached diagrams are for demonstration and observation purposes only; the seatbelt bracket 1 is shown in a way that facilitates display and observation. In actual use, it needs to be rotated and adjusted according to the installation position.
