Description

Technical Field

[0001] The utility model belongs to the technical field of seat belts, and specifically relates to an automobile seat belt assembly that is convenient to plug in. Background Art

[0002] The function of an automobile seat belt is that when a vehicle collides or uses emergency braking, the pre-tightening device will instantly retract and tighten the loose seat belt when worn, firmly tying the occupant to the seat to prevent a secondary collision. Once the retracting force of the seat belt exceeds a certain limit, the force-limiting device will appropriately loosen the seat belt to keep the chest force stable. Therefore, the automobile seat belt plays a role in restraining displacement and buffering, absorbing impact energy, resolving inertia force, and avoiding or reducing the degree of injury to the driver and passengers.

[0003] Existing automobile seat belts are all arranged at the bottom on one side of the seat. Sometimes, for a driver with a relatively bulky build, it is impossible to quickly insert the seat belt plug into the buckle, which is likely to cause the driver to be nervous and there are certain safety hazards. Therefore, a buckle that is convenient to plug in is needed so that the driver can quickly find the position to fasten the seat belt. Summary of the Utility Model

The first limiting block 14 is fixedly arranged on the inner side of the top of the mounting seat 4 and the buckle 6 can slide up and down in the mounting seat 4 through the second sliding groove 12. The third sliding groove 13 is opened on the side of the first limiting rod 9 far from the pushing block 11. The second limiting block 15 is fixedly arranged on the inner side of the top of the mounting seat 4 close to the third sliding groove 13;

[0023] A traction device for pulling the buckle 6 is arranged between the mounting seat 4 and the retractor 2;

[0024] The traction device includes a turntable 16, a traction rope 17, a first pulley 18, a second pulley 19 and a fixing ring 20. The turntable 16 is fixedly arranged on the outside of the winder 2, the first pulley 18 is fixedly arranged at the rear of the winder 2, the second pulley 19 is fixedly arranged at the bottom of the connection end 5, and the fixing ring 20 is fixedly arranged at the top of the first limiting rod 9.

[0028] Further, the winder 2, the mounting seat 4 and the connection end 5 are all fixedly arranged in the vehicle by bolts.

[0029] In the embodiment of the present utility model, please refer to Figures 1 - 3 , during daily use, the driver first pulls down the seat belt main body 1. At this time, the winding shaft 21 in the winder 2 rotates self - driven under the tension, and the winding shaft 21 drives the turntable 16 outside the winder 2 to rotate self - driven. The traction rope 17 on the turntable 16 finally pulls the fixing ring 20 through the first pulley 18 and the second pulley 19. The fixing ring 20 pulls the first limiting rod 9 at the bottom. At this time, the tension of the traction rope 17 exceeds the tension of the tension spring 8 at the bottom of the first limiting rod 9. Therefore, the first limiting rod 9 can slide up and down in the first empty slot 7. The pushing block 11 at the top of the first limiting rod 9 can abut against the first sliding slot 10 and push the buckle 6 upward. At this time, as the driver pulls the seat belt, the buckle 6 will also slowly rise from the mounting seat 4. The second limiting block 15 on the mounting seat 4 can limit the first limiting rod 9 to prevent the first limiting rod 9 from disengaging from the first empty slot 7 under the tension of the traction rope 17. The first limiting block 14 on the mounting seat 4 can limit the buckle 6 to prevent the buckle 6 from disengaging from the mounting seat 4 under the action of the pushing block 11. When the driver unfastens the seat belt, at this time the winder 2 retracts the seat belt, the winding shaft 21 pulls the turntable 16, and the traction rope 17 loses the tension of the turntable 16. At this time, the tension spring 8 pulls the first limiting rod 9 so that the first limiting rod 9 returns to the first empty slot 7 again. After the buckle 6 loses the thrust of the pushing block 11, it slowly slides into the mounting seat 4 under the influence of gravity.

[0030] Please refer to Figure 3, in the utility model, the diameters of the turntable 16, the first pulley 18 and the second pulley 19 adopted are well adapted to the length of the safety belt pulled by the driver. When the driver pulls the safety belt, through the conversion of the traction rope 17 by the turntable 16, the first pulley 18 and the second pulley 19, the displacement amount generated by the first limiting rod 9 is within the tolerable range, ensuring the durability of the mounting seat 4.
