Vehicle Application and Placement

The presented seat belt is dedicated to the rear bench seat of the Audi A4 B8 generation and operates in the center position, with the possibility of installation on both the left and right sides. This placement allows for consistent mounting geometry with the factory anchor points, which contributes to stable passenger restraint during driving and in emergency situations.

The structural solution used in this seat belt model is optimized for operation within the rear bench seat system, taking into account the characteristic profile of the Audi A4 B8 backrest and seat. Thanks to this, the element cooperates with the factory seat mountings, without disrupting the ergonomics of folding and unfolding the rear bench.

Technical and Functional Characteristics

The original Audi seat belt is designed as part of the vehicle's passive safety system. The webbing, retractor, and mounting elements form a cohesive system designed to:

• control the passenger's body displacement during sudden braking,
• maintain predictable vehicle behavior under the load of passengers on the rear bench,
• ensure proper cooperation with the seat structure and body anchor points.

As an original part, the belt complies with Audi's homologation requirements for this model, which translates to appropriately selected retractor characteristics and webbing guidance geometry. This facilitates installation and reduces the risk of improper belt positioning relative to the passenger's torso and hips.

Part Condition and Service Application

The seat belt comes from secondary circulation, making it a cost-effective solution while maintaining factory compatibility with the Audi A4 B8. This type of component is often chosen for:

• post-accident repairs of the rear body section,
• replacement of worn or damaged seat belts on the rear bench,
• restoring the car to its factory specification after modifications to the upholstery or seat structure.

Using an original belt from the same model line helps to minimize issues with fitment, mounting play, or improper retractor operation that can occur with aftermarket alternatives of different geometry.

Benefits of Using an Original Audi Seat Belt
