Purpose and Fitment for Mercedes W164

• stable mounting to the body structure, in line with the manufacturer's specifications.

Construction, Color, and Interior Integration

The belt is black, allowing it to harmoniously blend with typical interior configurations of Mercedes SUVs. The neutral color facilitates its use both as a replacement part after accident repairs and for supplementing missing equipment.

Key construction features:

• standard webbing width used in Mercedes seat belts,
• designed geometry of the buckles for factory mounting points,
• compatibility with standard upholstery elements in the rear left area.

Rear Belt Safety and Functionality

The rear seat belt in the Mercedes W164 is responsible for stabilizing the passenger's posture during driving, emergency maneuvers, and collisions. A correctly selected, original part helps maintain the protective parameters intended by the vehicle manufacturer.

Using the correct rear left belt contributes to:

• maintaining predictable safety system behavior during sudden braking,
• proper interaction with seats and ISOFIX mountings (if present in the specific vehicle configuration),
• meeting technical inspection requirements regarding belt completeness and functionality.

Condition, Origin, and Service Application

This part comes from the group of used Mercedes parts, making it an attractive solution for accident repairs, replacing a damaged belt, or restoring the vehicle to full functionality after safety system deployment. Choosing an original part from disassembly allows for maintaining the original mechanism's performance parameters while optimizing service costs.

The rear left belt is particularly suitable in situations where:

• a single belt needs replacement without affecting other system components,
• preserving the original specification is important instead of using aftermarket alternatives,
• compliance with Mercedes service documentation and repair procedures is crucial.
