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.

An arm rest frame (1) includes at least one frame component (7, 8, 9, 11). The at least one frame component (7, 8, 9, 11) is made from a organosheet. An arm rest and a method for producing an arm rest frame (1) are also provided.

The invention relates to a method for manufacturing a finished part comprising: a step of placing a trimmed finishing shell inside a heated mold chosen from a first mold referred to as a female mold and a second mold referred to as a male mold in the form of a punch, a step of heating a structural part made of a composite material up to its melting point, a step of placing the structural part on the finishing shell, a step of shaping the structural part against the finishing shell by means of the male mold in the form of a punch cooperating with the female mold, such that the finishing shell is fixed to the structural part that was shaped to obtain the finished part.
