Seat Belt Purpose and Function

The presented Seat Belt with Pretensioner Rear Left for Mercedes W204 is responsible for securely holding a passenger in their seat during driving and in emergency situations.

The black hue of the belt allows for an aesthetically pleasing integration into most interior configurations, without requiring modifications to other upholstery or trim plastics.

Construction and Fit for Mercedes W204

The belt has been specifically designed for the W204 platform, which translates to:

• Factory mounting points – compatible with original body anchors, eliminating the need for bodywork modifications.
• Correct belt path geometry – adapted to the shape of the pillar and rear seat.
• Integration with the factory pretensioner – prepared for cooperation with the vehicle's control systems.

This ensures that installation is similar to replacing a factory component, and the entire system maintains the parameters intended by the vehicle manufacturer.
