1.         Description About Retractor

The seat belt retractor is the core part of the car seat belt assembly. The emergency locking seat belt retractor (ELR) has two basic functions, one is emergency locking, and the other is free retraction and pullout.

The working principle of the sense locking mechanism:

* When the webbing is pulled out, it drives the mandrel to rotate (the acceleration is small at this time), so that the outer teeth of the disc and the reel wheel have a chain reaction to rotate without a large amplitude. Because there is a telescopic spring between reel and the outer teeth of the disc, which restrains the swing of the balance reel wheel in Toyota Seat Belt Retractor.

*As the webbing is pulled out faster, when the acceleration reaches a certain value, the retractor wheel will overcome the spring force and then lift up, so that the tip of the balance wheel meshes with the teeth on the inside of the locking cover, causing the outer teeth of the disc to get stuck Death cannot turn. But the mandrel continues to rotate, pushes the pawl to engage with the bracket until the mandrel stops rotating, the webbing is locked, and the belt-sensing locking function is completed.

*When the acceleration decreases and returns to the range of the set value, the webbing can be pulled out.
