Description

Technical Field

[0001] The utility model relates to the technical field of vehicle seat belts, in particular to a vehicle seat belt height adjuster. Background Art

[0002] A seat belt height adjuster is a fitting on the seat belt of a vehicle, used to adjust the height of the seat belt. Passengers can adjust the height of the seat belt according to their own height to improve the comfort of riding.

[0003] Currently, when in use, there is friction between the guide sleeve and the guide rail of the seat belt height adjuster, so that when adjusting the height of the seat belt, due to the resistance, users need to use a greater force to adjust, which is not conducive to adjusting the height of the seat belt; at the same time, when the seat belt is pulled out, the seat belt and the connecting plate adopt a sliding method. However, this method results in relatively large friction between the seat belt and the connecting plate, making the resistance to pulling out the seat belt relatively large, which is not conducive to pulling out the seat belt.

[0004] Based on this, a vehicle seat belt height adjuster with small friction is designed. Summary of the Utility Model

[0005] Aiming at the deficiencies of the existing technology, the utility model provides the following technical solution: a vehicle seat belt height adjuster, including a main body, a guide sleeve and a guide rail. The guide sleeve is fixed on the back of the main body. A connecting plate is rotatably installed at the lower part of the main body. The guide sleeve is sleeved outside the guide rail. Sliding mechanisms are arranged at both ends of the guide sleeve, and the sliding mechanisms are used for the guide sleeve to move along the guide rail; a support shaft assembly for guiding the seat belt is installed at the lower part of the connecting plate.

[0006] As an improvement of the above technical solution, the sliding mechanism includes a ferrule integrally formed at both ends of the guide sleeve. The ferrule is in a "U" - shaped structure. The ferrule is sleeved outside the edge of the guide rail. A plurality of first support wheels distributed in a straight line are installed on the inner surface of the middle part of the ferrule. Two groups of second support wheels are also installed on the inner surface of the ferrule, and the two groups of second support wheels are symmetrical about the first support wheels. Wheel grooves are opened at both ends of the guide rail, and the second support wheels are in contact with the surface of the wheel grooves.

[0007] As an improvement of the above technical solution, one first support wheel and two second support wheels are distributed in a triangular pattern.

[0008] As an improvement of the above technical solution, the support shaft assembly includes two support shafts rotatably installed at the lower part of the connecting plate and a limiting shaft. The limiting shaft is located at the symmetry axis of the two support shafts. Retaining rings for side - limiting the seat belt are integrally formed at both ends of the support shafts.

[0009] As an improvement of the above technical solution, the limit pressing shaft includes a shaft rod and a rubber sleeve adhesively fixed to the outer surface of the shaft rod, and anti-slip convex lines are integrally formed on the outer surface of the rubber sleeve.

[0010] As an improvement of the above technical solution, the rubber sleeve contacts the retaining ring, and a guiding cavity for guiding the seat belt is formed between the support shaft and the rubber sleeve.
