Trim component for vehicle interior

A trim component for vehicle interior is disclosed. A method for forming the trim component is also disclosed. The trim component comprises a cover material, a base layer, a foamed plastic, and a support element. The base layer is intended to prevent foamed plastic from penetrating into the pores of the cover material. Foamed plastic is injected between the base layer and the support element to form the trim component. The method comprises the steps of producing a base layer, applying and fixing at least part of the cover material to the base layer to form a pre-laminate, introducing the pre-laminate into a foaming mold with the base layer between the cover material and a foam chamber (between the pre-laminate and the support element) within a foaming mold and introducing foamed plastic into the foam chamber to form the trim component.
