Construction and Function of the Seatbelt Pretensioner

The seatbelt pretensioner is a crucial element of the safety system, responsible for quickly tightening the seatbelt to the driver's body in the event of a collision. It works in conjunction with collision sensors and the airbag control unit, activating in a fraction of a second to limit body movement relative to the seat.

The original Volkswagen design ensures:

• precise operation within specified overload thresholds,
• proper cooperation with the driver's airbag,
• stable mounting to the seat structure or center tunnel,
• preservation of the vehicle's factory safety parameters.
