What is a seatbelt pretensioner

Question

Accepted Answer

A seatbelt pretensioner is a safety feature in vehicles that tightens the seatbelt in the event of a collision to reduce the forward movement of the occupant.

Seatbelt pretensioners are activated by sensors that detect a collision or sudden deceleration.
They work by retracting the seatbelt to remove any slack and secure the occupant in their seat.
This helps to reduce the risk of injury by minimizing the forward movement of the occupant during a crash.
Seatbelt pretensioners are often paired with airbags to provide additional protection in a collision.

Accepted Answer

It's a device that locks the seatbelt when a vehicle is involved in a serious accident and locks the seatbelt.
