Purpose and Function of the Seat Belt Buckle Pretensioner

The placement on the left side of the vehicle means it is designed for the driver's seat or the left passenger seat (depending on the body version and market), which facilitates part selection for post-accident repairs or interior upgrades.

• Factory mounting points – no need for structural modifications to the seat or body,
• Compatibility with the original seat belt – correct working angle and buckle length,
• Integration with the safety system – intended cooperation with the airbag system and control unit by the manufacturer.

Such precise fitting minimizes the risk of installation errors and makes it easier to maintain the vehicle in a standard compliant with the manufacturer's specifications.
