Left Side 3-Point Seat Belt for BYD Seal High-end Version Vehicle Seat Belt Assembly

What is the difference between seat belts with warning devices and those without?

1. It reacts more quickly and intelligently during a collision;

2. A regular safety belt only tightens when the tension increases, while the alarm system (pre-tensioner) can instantly tighten the safety belt at the moment of impact (even before the impact) through an explosion or motor operation, eliminating slack and fixing the person in the seat. At the same time, the force-limiting function will automatically release when the tension is too high, reducing the pressure on the body and providing more comprehensive safety protection. It can even alert of fatigue driving.

   Regular seat belt (without warning device)

   Operation mode: Relying on the inertia reel (emergency self-locking function), when the belt is rapidly pulled out during sudden braking or collision, the ratchet on the reel will lock, stopping the belt.

Features: Passive restraint, with relatively slow response, there is a gap for the belt to slack, and the occupant still has a distance to move forward.

• Collision moment

  : The sensor detects the collision and triggers the pre-tensioner (gas generator or motor), instantly tightening the seat belt, eliminating the gap, and securing the person more firmly to the seat, reducing displacement.

• Frontal protection

  : Even before the collision, it can be pre-tensioned in advance to correct the sitting posture, enabling the passive safety system (such as airbags) to work more effectively.

• Buffering effect

  : When the force exerted by the seat belt on the body reaches a certain limit, the limiter will slightly release the seat belt, absorbing some impact energy, reducing the compression of the seat belt on the chest and shoulders, and preventing secondary injuries.

• Fatigue monitoring

  : Some advanced systems can monitor the driver's fatigue and use seat belt tightening + vibration to remind the driver to rest.
