Seat Belt Buckle Assembly

 Strong Locking for Long Use

We produce the seat belt buckle assembly as a core safety part. This product uses a strong lock structure and a long-life design. For passenger cars, the insert and pull cycle lasts ≥10,000 times. For commercial vehicles, it lasts ≥20,000 times. The lock holding force is ≥15 kN. That means it does not open under 1.5 tons of pull. Some batches reach 18 kN. This safety level is much higher than the standard.

Easy to Open and Rust Proof

The opening force changes with the car model. For passenger cars, it is 40N–150N. For commercial vehicles, it is a bit heavier. You can still use it with gloves. After 20,000 life tests, the lock force is still good. The buckle does not get loose or fail over time. Metal parts pass a 72-hour salt spray test. They do not rust or stick. This works well near the sea, on ships, or in wet areas. The lock has deep teeth and a strong spring. It does not slip or open by mistake. Even on bumpy roads, it stays stable.

Certified and Dependable

Flame-proof parts can take high heat and do not melt. They meet car safety rules. This seat belt buckle assembly has 3C and E-MARK certificates. We also hold three structure patents. In our factory, every buckle is tested for opening force and lock force before it leaves. This seat belt buckle assembly gives you strong locking, a very long life, and high rust protection. It is a core and reliable part for car makers and replacement needs.
