This cover conceals the seat belt anchor plate, protecting it from dirt, moisture, and wear. It also enhances the interior appearance by hiding exposed mounting hardware, ensuring a neat and factory-correct finish. Additionally, it helps prevent accidental contact with sharp or protruding components.
Function
The primary function of this component is to act as a protective and cosmetic cover for the seat belt anchor point. It reduces exposure to contaminants that could lead to corrosion while maintaining the integrity of the mounting area. By securing over the anchor plate, it also contributes to passenger safety by minimizing interference with the seat belt mechanism.
Over time, original anchor plate covers can become cracked, faded, or go missing entirely. This not only detracts from the vehicle’s interior aesthetics but also leaves the anchor point exposed to damage and corrosion.
Replacing a worn or missing cover helps preserve originality, maintain value, and protect critical mounting hardware.
When to replace
• Cover is cracked, broken, or missing
• Visible fading or discoloration affecting interior appearance
• During interior restoration or refurbishment
• After seat belt or anchor point servicing
• Signs of loose or poor fitment

Also referred to as a seat belt anchor cover, upper B-pillar protection cap or seat belt mounting bolt cover, this component provides a protective and decorative finish over the corresponding seat belt anchorage hardware.
The cap is designed to fit over the original-style upper shoulder belt mounting arrangement, concealing the exposed metal fitting and helping maintain the factory appearance of the passenger compartment.
On early Porsche 911 and 912 vehicles, the seat belt anchorage is a prominent part of the interior trim. The protection cap provides a neat finishing detail, helping the mounting assembly blend with the surrounding interior.
The cap is commonly associated with the distinctive cloverleaf-style upper seat belt anchorage cover used on selected early models.
Manufactured as a Genuine Porsche original equipment component, it is intended to match the relevant original seat belt mounting arrangement.
Although the cap does not form part of the seat belt's load-bearing structure, it helps cover exposed hardware, reducing direct contact with the metal fitting and limiting the accumulation of dust around the mounting area.
Over time, original seat belt protection caps may deteriorate because of age, sunlight exposure, repeated contact or removal during seat belt servicing.
The material may become brittle, cracked or loose, while retaining features can break and prevent the cap from remaining securely fitted.
A damaged or missing cap leaves the seat belt anchorage exposed and can detract from the appearance of an otherwise well-maintained classic Porsche interior.
Replacing a damaged cap with a Genuine Porsche component helps restore the original trim finish, maintain correct coverage of the anchorage hardware and preserve the vehicle's period-correct interior appearance.
What This Product Does:
The seat belt protection cap is fitted over the designated upper seat belt anchorage assembly.
Its primary function is to cover the exposed mounting hardware and provide a finished appearance to the seat belt installation.
The seat belt anchorage connects the restraint assembly to the vehicle body using a specified mechanical fastening arrangement.
The protection cap conceals the visible anchorage fitting without replacing or altering the structural mounting hardware.
Its main functions include:
- Covering seat belt anchorage hardware: Conceals the exposed upper mounting fitting.
- Providing a finished interior appearance: Maintains the original trim detail around the seat belt attachment.
- Reducing contact with exposed metal: Provides a covering over the designated mounting hardware.
- Limiting dust accumulation: Helps protect the covered area from everyday dirt and debris.
- Maintaining original seat belt trim: Preserves the factory-style anchorage cover arrangement.
- Supporting interior restoration: Replaces missing or deteriorated trim following seat belt repairs.
- Maintaining correct visual fitment: Provides the specified shape for the corresponding anchorage fitting.
- Reducing loose trim movement: Restores secure coverage where the original cap has become detached.
- Completing the seat belt assembly appearance: Provides the finishing component around the upper mounting point.
- Preserving vehicle originality: Maintains a period-correct interior detail on compatible classic Porsche models.
Symptoms Of Wear Or Failure:
The seat belt protection cap is a passive interior trim component without moving mechanical parts.
Ageing, repeated handling, previous seat belt repairs and exposure to sunlight may cause deterioration.
Common signs of a worn or damaged protection cap include:
- Visible cracks: The cap may develop cracks as the material ages.
- Broken retaining features: Damaged attachment points may prevent secure fitment.
- Loose cap: The component may no longer remain firmly positioned over the anchorage.
- Missing protection cap: The upper seat belt mounting hardware may be left exposed.
- Brittle material: Age-related deterioration may cause the cap to break during handling.
- Discolouration: Prolonged exposure to sunlight may change the original appearance.
- Scratched surface: Normal use or previous servicing may damage the finish.
- Distorted shape: Physical damage may prevent the cap from seating correctly.
- Poor fitment: Incorrect replacement components may leave gaps around the mounting.
- Partial detachment: The cap may sit unevenly or separate from the anchorage fitting.
- Rattling or movement: A loose cover may produce minor trim noise.
- Damage following seat belt servicing: Removal and refitting may damage an ageing cap.
- Uneven interior appearance: A missing or discoloured cap may contrast with the opposite side.
- Visible exposed hardware: Loss of the cover may leave the original mounting assembly unfinished.
Why Replacement Matters:
Replacing a damaged seat belt protection cap helps restore the original appearance and completeness of the seat belt anchorage assembly.
A cracked, loose or missing cap leaves the mounting hardware exposed and may detract from the interior finish.
On early Porsche 911 and 912 models, small trim details are important to maintaining a faithful restoration and original factory appearance.
Installing a Genuine Porsche replacement Seat Belt Protection Cap helps to:
- Restore the original interior finish: Replace damaged or missing seat belt anchorage trim.
- Conceal exposed mounting hardware: Reinstate the intended cover over the upper anchorage.
- Maintain period-correct appearance: Preserve the original-style Porsche interior detailing.
- Replace deteriorated material: Renew cracked, brittle or distorted caps.
- Improve component fitment: Restore secure attachment where the original cover is defective.
- Reduce unwanted trim movement: Replace a loose cap that no longer seats correctly.
- Maintain visual consistency: Match the original appearance of the left- and right-hand anchorage areas.
- Support seat belt refurbishment: Complete the trim installation following seat belt servicing.
- Protect the covered mounting area: Help limit everyday contact and dust accumulation.
- Support classic Porsche restoration: Renew an often-missing interior detail.
- Preserve vehicle originality: Use the corresponding Genuine Porsche part.
- Avoid unsuitable universal covers: Maintain compatibility with the specified anchorage arrangement.
Replacement is recommended when the cap is missing, cracked, heavily discoloured, distorted or unable to remain securely fitted.
If the underlying seat belt anchorage is loose, damaged or corroded, the anchorage must be inspected and repaired independently before the cap is fitted.
