Retractor has a locking mechanism, can stop the scroll in the automobile crash rotation.Now, there are two kinds of commonly used locking system: system triggered by the automobile movement and system safety belt movement triggered by.
The first system in the car rapid deceleration (for example, when an object when the car hit) locking reel. The core element of the institutions is an aggravating pendulum. When the car suddenly stopped, the inertia will cause the pendulum swings forward. The other end of the pendulum will grab a toothed ratchet is fixed on the reel. Because of the pawl stuck one tooth, so the gear can’t counterclockwise rotation, so that the reel is connected with the cannot rotate. When the collision again after the release the safety belt, gear will rotate clockwise, and the ratchet wheel and separate.
Second systems in the safety belt locking reel at. Most design using the reel rotation speed as the activation power. The core element of this design is a centrifugal clutch, a mounted on a rotating reel aggravated pendulum. When the spool rotates slowly, the pendulum rod does not swing. A spring to keep it in the original position. But when the tug the safety belt, scroll to rapid rotation, centrifugal force driven pendulum weighting end swing outwards.
Good maintenance play an important role in car,but car diagnostic tool are necessary.
