Each component is manufactured from durable webbing and corrosion-resistant hardware to meet the demands of road and track environments. Perfect for restoration projects, safety upgrades, or replacements, our products ensure Porsche-standard quality, function, and appearance.

What Do Rear Seat Belts Do?

Rear seat belts provide safety, comfort, and legal compliance, ensuring that passengers are properly restrained during travel.

Core Functions:
• Protect passengers in the event of sudden braking or collisions.
• Distribute impact forces evenly across the upper and lower body.
• Maintain correct passenger seating position for maximum safety.
• Reduce cabin movement and enhance occupant comfort.
• Support compatibility with child seat anchoring systems (ISOFIX in modern models).

A properly functioning seat belt system is critical not only for safety but also for maintaining the integrity and comfort of your Porsche’s cabin.

Why Do Rear Seat Belts Fail or Degrade?

Even though rear seat belts are used less frequently than front belts, they can still deteriorate due to environmental exposure, age, and mechanical fatigue.

Common Causes of Failure Include:
• Webbing fray, fading, or weakening from UV exposure.
• Sticking retractors or locking mechanism failure.
• Corrosion on mounting bolts and anchors.
• Contamination from dirt, oils, or cleaning chemicals.
• Previous accident stress weakening the belt’s strength.

Worn or damaged rear seat belts compromise both passenger safety and vehicle compliance — making replacement essential for proper protection.
