Vehicle Application and Placement

The seat belt height adjuster is designed for use on the front axle of the vehicle, with the possibility of mounting on either the left or right side. This allows it to be used as a replacement for either front position, in accordance with the W203 body's factory configuration.

The component works in conjunction with the factory seat belt anchor, the pillar guide, and the retractor mechanism. A correctly selected and installed adjuster helps to:

• Set the optimal belt height relative to the user's shoulder,
• Reduce localized pressure on the shoulder and neck area,
• Maintain stable belt guidance during normal driving and sudden braking.

Technical and Functional Characteristics

The seat belt height adjuster for the Mercedes W203 is a mechanical component that interacts with the vehicle's pillar structure. The adjustment mechanism allows for changing the position of the upper seat belt anchor point in several working positions, enabling adjustment to the user's height and seat geometry.

Key features of this component include:

• Compatibility with the factory safety system in the Mercedes W203,
• Maintaining the original belt routing geometry relative to the pillar and seat,
• Mechanical height adjustment using the original mounting points.

A properly functioning adjuster is important not only for comfort but also for the performance of passive safety systems – correct belt routing influences how the chest and shoulder area are loaded in the event of a collision.

Brand, Origin, and Item Condition

The offered adjuster is a part intended for Mercedes vehicles, ensuring compatibility with the W203 body structure as per the manufacturer's specifications. The item is from a dismantled vehicle and is classified as used, making it a cost-effective solution while maintaining compliance with the factory seat belt mounting system.

Choosing an original part from dismantling allows you to:

• Maintain structural consistency with other safety system components,
• Minimize the risk of installation issues arising from dimensional differences,
• Retain factory mounting points without the need for body modifications.

Why Use a Dedicated Seat Belt Height Adjuster

Using the correct seat belt height adjuster in a Mercedes W203 directly impacts ergonomics and safety. A properly selected component:

• Improves driving comfort by adapting the belt path to the user's physique,
• Reduces the risk of incorrect belt positioning (too high on the neck or too low on the shoulder),
• Supports the proper function of pretensioners and retractors in emergency situations.

When upgrading or repairing the seat belt system, it is advisable to use components specifically designed for the particular model and body generation to ensure predictable vehicle behavior in crash tests and real-world driving incidents.
