A:
Are your seat belts still working properly? Most seat belts are designed only to work in one major collision. After that, the internal parts will not work exactly right. You would need to talk to an engineer to figure out why; but, basically like a bicycle or motorcycle helmet, they are only good for one major collision. After this, you have to have them inspected or replaced. It is not actually the belt that is damaged, but the locking mechanism in the shoulder belts. This is the part that locks when a collision occurs. There is a pendulum inside and it works only one time. Generally the insurance adjuster or body shop will not look at the pendulum or seat belts unless you ask.
