Purpose and Function in the Vehicle

The presented trunk upholstery is intended for installation in the rear of the body, where it is responsible for soundproofing the cargo area and protecting the metal body elements. The component's design has been developed to:

• limit noise penetration from the rear axle and underbody area,
• increase acoustic comfort in the passenger cabin,

The element serves as both a cover and sound deadening, combining protective and acoustic functions. The material structure has been selected to:

• dampen vibrations and noise coming from the rear of the body,
• maintain adequate rigidity with low weight,
• allow for multiple disassembly and reassembly during service work in the trunk.

Properly profiled edges facilitate fitting to body contours, and designated mounting points allow for seamless integration with other trunk trim elements. This solution is particularly useful for work related to servicing installations located in the rear of the vehicle.

Service Application and Benefits of Installation
