Purpose and Technical Function

The presented foam bumper carrier has been developed by the manufacturer for installation in the rear section of Mercedes vehicles from the C253 series. Its function is to control the absorption of collision energy and stabilize the outer bumper cover, thereby reducing the transfer of loads to the car's structural components.

The element acts as a buffer between the bumper and the metal reinforcement, assisting in:

• reducing local deformations in minor rear-end collisions,
• maintaining the correct position of the bumper relative to the body,
• preserving factory gaps and styling lines.

Construction and Body Fitment

The absorber is made from a carefully selected foam with controlled density, allowing for elastic deformation under load and return to its original shape within the manufacturer's specifications. The element's profile is tailored to the rear body structure of the C253, ensuring compatibility with factory mounting points and reinforcements.

Original Mercedes origin means:

• maintaining the correct length and shape in the horizontal plane,
• compatibility with the factory rear bumper,
• consistency with the vehicle's passive safety system.

Vehicle Placement and Role in the Safety System

The element is designed for installation in the rear body zone, directly behind the outer bumper cover. In the event of a rear impact, the foam carrier works in conjunction with the bumper reinforcement and the body structure, distributing forces over a larger area and limiting point loads.

As a result, the absorber is a crucial link between the exterior styling and the supporting structure, contributing to:

• more uniform energy dissipation,
• reduced risk of damage to components located behind the bumper,
• maintaining the correct geometry of the rear of the vehicle after minor collisions.

Performance Characteristics and Installation

The offered absorber is a used part, which allows for an economical repair of the rear body section while maintaining the original manufacturer's specifications. Replacement with an OEM part of the correct shape and stiffness is particularly important after parking damage or minor collisions, when the outer bumper has already been repaired or replaced.

Due to its factory origin, installation is carried out in the locations designated by the manufacturer, without the need for body modifications. Installation in a service environment is recommended, following the vehicle manufacturer's procedures, to ensure proper interaction with other elements of the rear crumple zone.
