Intended Use and Fitment for BMW

The presented seat belt has been specifically designed for BMW E63 series models, intended for installation on the front left side of the cabin. The original BMW construction ensures:

• precise alignment with the mounting points in the body,
• correct tape routing geometry relative to the seat and pillar,
• proper interaction with the vehicle's factory pretensioners and safety systems.

This ensures the belt maintains the parameters set by the manufacturer, which is crucial for effective driver protection.

Construction, Color Scheme, and Interior Integration

The belt webbing is made in an elegant, neutral Grey (Basalt Grey) shade, which blends well with typical BMW E63 upholstery configurations. This color choice allows for:

• aesthetic matching with factory door panels and dashboard,
• maintaining visual consistency when replacing only one belt,
• minimizing shade differences visible in daily use.

The original belt mounts and guides are designed to work with standard interior components, without the need for modifications or adaptations.

Technical Characteristics and Safety

As an OEM BMW part, the seat belt has been developed in accordance with the vehicle manufacturer's internal standards. This means that:

• the webbing's strength parameters are adapted to the mass and characteristics of the E63 body,
• the retractor mechanism operates with appropriately calibrated force, ensuring comfort of movement and proper tension while driving,
• the belt assembly is compatible with the passive safety systems designed for the driver or front left passenger position.

Such structural matching directly impacts vehicle behavior and occupant protection in emergency situations.

Condition, Origin, and Practical Application

The offered item is a used BMW seat belt, providing a cost-effective solution for those seeking original components at a reasonable price. Choosing a used part makes sense particularly when you prioritize:

• maintaining factory quality of workmanship instead of using aftermarket replacements of unknown origin,
• interior visual consistency with the other seat belts,
• reducing repair costs while maintaining BMW safety standards.

Before installation, it is recommended to verify compatibility with your specific vehicle's equipment version and to have the installation performed by an experienced service center familiar with passive safety systems.
