• correct tensioner operation in an emergency situation,
• comfortable access to the buckle for rear seat passengers.

Technical and Functional Characteristics

The rear right lower belt tensioner is part of the passive safety system, working in conjunction with the vehicle's electronics and collision sensors. As an original BMW part, it has been designed for the specific E65/E66 platform, which translates to:

• precise fit to the seat and body structure,
• compatibility with the factory SRS system (airbags, sensors, control unit),
• secure mounting at the manufacturer-specified mounting points.

This type of solution allows you to maintain the original performance parameters of the safety system without the need for installation modifications or interior structural alterations.

Condition, Origin, and Benefits of Choosing a Used Part

The component comes from the seat belts and parts category and is offered as a used part. This means real cost savings while maintaining the characteristics of an original BMW component. Compared to aftermarket alternatives, an original buckle with a tensioner ensures:

• factory fit for the specific model without modifications,
• compatibility with the electrical system and control unit used in that generation of the 7 Series,
• visual consistency with other interior elements (shape, mounting, belt routing).
