Slow Motion Seatbelt Pretensioner!

The seatbelt pre-tensioners never gets any credit, this video shows what it does and how fast it works!

One of the most overlooked safety features of a car most people don’t even realize that this happens in the event of a crash! The seatbelt will pull its self downward and tighten up around the person in the seat to hold them closer! This works with a lot of other components in the car to keep you safe! They have two types the spring loaded and the explosive one, the amount of engineering that went into this part is crazy for something that will only work once. But it has to work perfectly once!
