Description

A seat belt under-fixing point mounting structure Technical Field

[0001] This utility model relates to the field of seat belt technology, and in particular to a seat belt lower fixing point installation structure. Background Technology

[0002] All cars must be equipped with seat belts, but as seat belt requirements become increasingly stringent, the lower anchor point connection structures vary due to differences in car body structure and performance standards. Some seat belts use an end-plate pre-tensioning and bolt-fixed structure for the lower anchor point connection; others use a steel wire rod and bolt-fixed structure. Although the retractor, webbing, and belt top assembly of a car seat belt are the same, the different lower anchor point installation structures require different production configurations for different car models. Changes in installation plans or the lower anchor point installation structure can lead to unsold seat belt assemblies, affecting installation and causing unnecessary waste. For seat belts where the retractor, webbing, and belt top assembly are the same, but the lower anchor point structure differs, a standardized connection structure for the lower anchor point of the seat belt retractor can be adopted. This allows for mass production of the seat belt assembly; only the lower anchor point installation structure needs to be changed according to the car model and configuration requirements. This standardization of seat belt assembly production and assembly reduces the risk of unsold inventory and facilitates mass production. Therefore, solving this problem is extremely important. Summary of the Invention

[0003] In view of this, the purpose of this utility model is to propose a seat belt fixing point installation structure, which solves the problems in the background art.

[0004] Based on the above objectives, this utility model provides a seat belt lower fixing point installation structure, including a seat belt body, a retractor connected to one end of the seat belt body, and a lower fixing point connector connected to the other end of the seat belt body. The lower fixing point connector includes two housings combined to form a whole, and a lock body is disposed inside the two housings. A rivet is fixedly disposed inside the lock body, and a return block is rotatably disposed on the rivet. A movable hole is opened on the surface of the lock body on one side of the return block. A limit stop is placed in the movable hole. Both ends of the limit stop are provided with protruding protrusions for limiting and locking the limit stop in the movable hole. The limit stop is initially located at the bottom of the movable hole. A hook is inserted from bottom to top at the bottom of the lock body. During the insertion process, the hook first contacts the limit stop and pushes it to contact the return block. The hook moves upward until it is locked at the top of the limit stop. The return block pushes the limit stop back to the initial position. A connecting structure is connected to the bottom of the hook.

[0005] Preferably, a spring is provided on the surface of the return block, with one end of the spring abutting against the lock body.

[0006] Preferably, the return block is provided with a fitting block on the side near the limiting block.

[0007] Preferably, both of the housings and the top of the lock body are provided with a through hole for the seat belt body to pass through and connect.

[0008] Preferably, the two housings and the bottom of the lock body are provided with a through groove for the movement of the hook.

[0009] Preferably, the seat belt body is further provided with a fork-shaped bracket, a guide ring and a locking tongue, and a height adjuster is provided on the guide ring.

[0010] The beneficial effects of this utility model are as follows: This utility model features a lower fixing point connector at one end of the seatbelt body. Hooks are provided on different connection structures. The hooks are inserted upwards into the lock body from the bottom of the two housings and the lock body. The hooks first contact the limiting block, which then contacts the fitting block of the return block, causing the return block to rotate. When the hook is engaged at the top of the limiting block, the spring action causes the return block to spring back, returning the limiting block to its initial position. In this way, the lower fixing point connector can securely engage the hook within the lock body. During production, regardless of the connection structure, installation is achieved simply by engaging the hook of the connection structure with the lock body, meeting production needs and avoiding inventory waste caused by changes in vehicle model configuration or plans. This facilitates mass production. The two housings and the top of the lock body have through holes for the seatbelt to pass through, and the bottom has through grooves for the hook's movement and engagement.

[0021] As shown in Figures 1 to 5, this embodiment provides a seat belt lower fixing point installation structure, including a seat belt body 1, a retractor 2 connected to one end of the seat belt body 1, and a lower fixing point connector 3 connected to the other end of the seat belt body 1. The lower fixing point connector 3 includes two housings 4 assembled together to form a whole, a locking body 5 disposed within the two housings 4, a rivet 6 fixedly disposed within the locking body 5, a return block 7 rotatably disposed on the rivet 6, and a spring 11 disposed on the surface of the return block 7. The end rests inside the lock body 5; the return block 7 is provided with a fitting block 12 on the side near the limit stop block 9; the surface of the lock body 5 is provided with a movable hole 8 on the side of the return block 7, the limit stop block 9 is placed in the movable hole 8, and the two ends of the limit stop block 9 are provided with protruding protrusions for limiting and locking the limit stop block 9 in the movable hole 8. The limit stop block 9 is initially located at the bottom of the movable hole 8; a hook 10 is inserted from bottom to top at the bottom of the lock body 5; the bottom of the hook 10 is connected to a connecting structure, which is an end piece pre-tightening structure or a wire rod structure. By setting a lower fixing point connector 3 at one end of the seat belt body 1, and setting hooks 10 on different connection structures, the hooks 10 are inserted upwards into the lock body 5 from the bottom of the two covers 4 and the lock body 5. The hooks 10 first contact the limit block 9, and the limit block 9 contacts the contact block 12 of the return block 7, thereby rotating the return block 7. When the hooks 10 are locked at the top of the limit block 9, the spring 11 causes the return block 7 to spring back, so that the limit block 9 returns to its initial position. In this way, the lower fixing point connector 3 can securely lock the hooks 10 in the lock body 5. In this way, regardless of the connection structure, installation can be achieved simply by locking the hooks 10 of the connection structure into the lock body 5, which meets the needs of production and avoids the waste of inventory caused by changes in vehicle configuration or plans, thus facilitating mass production.

[0022] Both of the housings 4 and the lock body 5 have through holes 13 at the top for the seat belt body 1 to pass through and connect; both of the housings 4 and the lock body 5 have through grooves at the bottom for the movement of the hooks 10.

[0023] One end of the seat belt body 1 is connected to a retractor 2. The seat belt body 1 is also provided with a fork-shaped bracket 14, a guide ring 15 and a locking tongue 16. The guide ring 15 is provided with a height adjuster 17. These are all components known in the prior art. The seat belt body 1 is wound up by the retractor 2, the height is adjusted by the height adjuster 17 by the guide ring 15, and the locking tongue 16 is used for fixing.
