How to Fix the Seat Belt Retractor – A Simple Guide

The webbing of the seat belt is coupled to a retractor, which also has a spool attached to one end. The spool is torqued by the seat belt retractor spring within. This causes it to spin, therefore tightening the seat belt webbing. A collision is not the only event that might cause the seat belts to tighten. 

The movement of the vehicle can cause the retractor to activate, which can then stop the spinning of the spool via a locking mechanism. The spool locks when the car decelerates suddenly, like in a collision, or even in a simple event such as a seat belt being ripped out quickly. Here’s a simple approach to fixing a seat belt retractor.

1. Check for Broken Parts

The first step is to check for any broken parts. Look at the spool, the locking mechanism and the spring. If any of these parts are damaged, then they need to be replaced before proceeding.

2. Check for Folds, Twists, Kinks

Next, check the webbing for any folds, twists or kinks. These can all cause the webbing to get stuck and prevent the spool from rotating. Gently straighten out any kinks or twists and make sure the webbing is lying flat.

3. Check for Grime, Dust or Food Particle Buildup

If there is grime, dust or food particle buildup on the webbing or spool, this can also cause problems. Use a soft cloth to wipe away any dirt or debris. You may need to use a mild soap and water solution if the build-up is more stubborn.

4. Soak the Belt in Soap and Water

If the webbing is still not sliding smoothly, you can try soaking it in a mild soap and water solution. This can help loosen any remaining dirt or debris. Let the webbing soak for a few minutes before proceeding.

5. Open the Panel or Casing to Check for Obstructions

Finally, if the problem persists, you may need to open up the panel or casing to check for any obstructions. Sometimes there can be something caught inside that is preventing the spool from rotating properly. Once you have located and removed the obstruction, reassemble the panel or casing and test the seat belt to see if it is working properly.

When to Replace Seat Belts

Although you can often fix minor issues with seat belts, there are some cases when it is best to replace them entirely. If the webbing is frayed, it needs to be replaced. Also, if the seat belt has been in a serious accident, it is recommended that it be replaced. Seat belts are designed to absorb impact during a collision, and once they have done so, they are no longer as effective.


Seat belts are an important safety feature in any vehicle. It is important to know how to properly care for and maintain them to ensure they are working properly. If you have any concerns about your seat belt, it is best to consult a professional.
