What are the reasons why the seat belt buckle cannot be inserted?

[LaRose]

The reasons why the seat belt cannot be inserted are as follows: Installation damage: If the seat belt cannot be inserted, first check whether the lugs of the mounting clamp on the seat are damaged. Generally, prolonged use may cause the buckle to fail to insert. Foreign object accumulation: If the seat belt cannot be inserted, check whether there are any foreign objects in the lugs of the mounting clamp on the seat. Accumulated debris or small items falling into the lugs can also prevent the buckle from being inserted. Seat belt retractor damage: The seat belt retractor is the device that retracts and releases the seat belt. If it is damaged and cannot be pulled, it will also create a safety hazard where the seat belt cannot be inserted.
