The presented item belongs to the Seat Belts and Parts category, meaning it is responsible for keeping the driver in the correct position during driving and in emergency situations. The belt's construction works with the vehicle's factory passive safety systems, ensuring:

• stable tape guidance along the pillar and seat, according to manufacturer's specifications,
• correct positioning of mounting points relative to the body structure,
• compatibility with the safety system designed for the specific W204 body variant.

Proper fitment of the belt to the model and installation side is crucial for maintaining predictable vehicle behavior in critical situations and for meeting homologation requirements.

Characteristics of the Used Part

The offered seat belt is a used part, sourced from dismantling. This type of component is a good choice for users seeking a reasonable compromise between repair cost and maintaining the vehicle's original specifications. In practice, this means:

• preservation of the factory construction specific to the Mercedes model,
• economical repair option for the safety system after a collision or malfunction,
• easier fitment compared to many universal aftermarket replacements.

Before installation, a standard inspection of the mechanical condition and the proper functioning of the retractor mechanism is recommended, in accordance with the vehicle manufacturer's service procedures.

Benefits of Using an Original Seat Belt

Choosing an original seat belt for the Mercedes W204 offers a number of practical advantages:
