Intended Use and Fitment for Mercedes W166

The presented rear left seat belt buckle has been specifically designed for Mercedes W166 series models. Its placement on the rear left side of the vehicle guarantees correct mounting geometry and proper interaction with the factory seat belt and rear bench. This ensures the component meets the manufacturer's safety performance requirements.

The black color of the housing and release button allows for an aesthetically pleasing integration into the original interior, without contrasts or shade differences. This is particularly important when replacing a single component in a premium vehicle, where both functionality and visual consistency are crucial.

Construction and Function of the Seat Belt Buckle

The buckle plays a crucial role in the passenger restraint system, responsible for securely locking and quickly releasing the belt buckle. The design includes:

• Stable mounting at the anchor point on the rear left side of the vehicle, which limits unwanted movement of the component during driving.
• Precise latch mechanism, ensuring a clear engagement of the belt buckle and controlled release upon pressing the button.
• Ergonomic button with an appropriate surface area, facilitating operation even with gloves on or in tight spaces between seats.
• Black housing, matching the typical upholstery and plastics used in the Mercedes W166.

This configured component ensures predictable operation of the rear seat belt system, which is important for both daily use and emergency situations.

• Compatibility with Safety System – The buckle works seamlessly with the existing seat belt and rear seat system.
