    Product Description

    1966-1971 Mercedes-Benz 250 S, Rear Driver & Passenger, Seat Belt Kit

    Seatbelt Planet's 1966-1971 Mercedes 250 S, Rear Driver & Passenger, Seat Belt Kit. 2 Point Non-Retractable Lap Seat Belt Kit with Lift Latch Buckles.

    The Seatbelt Planet 1966-1971 Mercedes-Benz 250 S, Rear Driver & Passenger, Seat Belt Kit, sold by Vintage Car Radio, is a refined and logical upgrade that completes the safety philosophy these elegant W108 sedans were always known for.
     
    The Mercedes-Benz 250 S was engineered with a seriousness of purpose that set it apart in the luxury segment. Built on a strong unibody platform with advanced crumple zones and exceptional build quality, it earned a reputation as one of the safest cars of its time. The rear compartment was designed for comfort and dignity — generous legroom, supportive seating, and a calm, quiet environment ideal for long-distance travel or being driven by a chauffeur.
     
    Many 250 S models served as proper executive sedans where rear passengers were often important people who expected to ride in comfort and security. Yet the original rear outboard belts were basic and have not aged well. After more than fifty years, surviving belts are frequently faded, weakened, or unreliable, creating a noticeable gap in a car that otherwise prioritized occupant protection.
     
    This Seatbelt Planet kit addresses that gap directly. It provides a matched pair of 3-point lap-and-shoulder belts engineered specifically for the 250 S rear bench. The high-strength webbing is fade-resistant and offered in colors and textures that complement the car’s refined original MB-Tex, leather, or restored interiors.
     
    The buckles are clean, reliable designs that deliver positive engagement and easy release. Hardware and fittings are discreet and well-finished, allowing the belts to integrate naturally with the 250 S’s understated rear cabin trim and wood accents. The result is safety equipment that feels appropriate rather than intrusive.
     
    Installation is clean and sympathetic to the car’s luxury construction. The kit includes all necessary mounting hardware and is designed to work with the existing rear floor points, typically requiring minimal modification. Adjustable straps ensure a secure, comfortable fit for rear passengers of different sizes while preserving the bench’s generous legroom and elegant appearance.
     
    Seatbelt Planet builds these kits to exceed FMVSS 209 and 302 safety standards, providing excellent tensile strength, durability, and flame resistance. For owners who still use their 250 S as a proper luxury sedan — whether for family trips, classic tours, or special occasions — this kit completes the car’s safety story and makes the rear seats truly ready for passengers.
     
    Vintage Car Radio stocks this Seatbelt Planet kit with reliable shipping and support, making the upgrade accessible for both careful restorers and regular drivers.
     
    This Seatbelt Planet 1966-1971 Mercedes-Benz 250 S Rear Driver & Passenger Seat Belt Kit is a natural extension of the car’s engineering-first DNA. It quietly strengthens the rear compartment while preserving the 250 S’s dignified, comfortable character.
     
    It allows you to carry passengers with the same level of care and confidence that Mercedes intended for the front seats. Order from Vintage Car Radio today and bring your 250 S’s rear bench up to the full safety standard its reputation has always suggested.
