First of all, if we are accustomed to pulling the seat belt too hard, the number of such jams will increase. Or, there are children in our family who like to play with the seat belt. The child is very happy to play. In fact, all have an impact on the life of the spring coiler.
In addition, if we install child seats in the car all the year round, the seat belt is also in such a strong and stretched state all the year round, which will also affect the life of the seat belt.
There is another reason that has the greatest impact on seat belts. If we often like to step on the brakes so hard, the seat belts are frequently jammed. Or the car has had an accident and suddenly slammed on the brakes, and the strength of the seat belt pulled up to the limit of the spring coiler. You can think about it. I pulled a spring hard. If it is within the range that it can bear, the spring will not be damaged. If the force is too large, it exceeds the elastic force range of the spring, and metal fatigue occurs, and the spring is deformed. Never return to the original state again. Suddenly stepping on the brakes or accidents are the easiest to impact the limit of the spring coiler. Therefore, in this case, the spring coiler is most likely to be damaged.
If the seat belt is used all the year round, it will also get dirty. We usually wipe it and wash it. If the seat belt is not completely dried before being caught, in fact, it may also cause damage to the spring coil. Rust is possible.
