This part of your seat belt system keeps you safe while you're driving.

When you pull your seat belt across your body, the retractor is the component that pulls it back in tightly after you've buckled. This piece is also responsible for retracting the entire seat belt when you unbuckle, and it holds it in place to keep you from flying out of your seat during an accident.
