What Causes Seat Belt Noise?

[WillowFitz]

The cause of abnormal noise from the car seat belt buckle is its friction or contact with the passenger seat. It could also be due to slippage between the belt and the pulley, leading to the noise. Another possible reason is loose fixing screws of the seat belt. If it's a new car still under warranty, you can simply have the 4S store handle it during maintenance, or you can deal with it yourself. More relevant information is as follows: 1. Solution: Prevent the seat belt buckle from contacting the seat. The passenger seat belt buckle may be too tightly damped, or the screws under the passenger seat may not be tightened or fastened properly. It might not be the seat that's loose but the base underneath; tightening it should suffice. 2. Note: Since the pin joint between the shaft pin and the bracket, as well as the hole on the base, has a certain gap, driving on cobblestone roads can cause the shaft pin to hit and produce noise. Additionally, there might be a gap between the flat washer at the shaft pin and the limit base, causing the washer to hit the base and create noise during driving. If the limit rod inside the angle adjuster is too loose or the adjuster's fixing bolts are loose, applying some lubricating oil can help.
