Upholstery element with a backing featuring two structural patterns, and associated process

Abstract

Trim element with a back-facing skin featuring two structural patterns, and associated method. The present invention relates to a trim element (10) for a vehicle comprising a support piece (12), a foam layer (14), and a skin (16), the foam layer (14) extending between the support piece (12) and the skin (16). The back face (20) of the skin (16) against the foam layer (14) has an adhesion structural pattern (22) and a ventilation structural pattern (24). The adhesion structural pattern (22) comprises hollows and / or raised areas having a respective depth less than or equal to a first depth (d1). The ventilation structural pattern (24) comprises hollows and / or raised areas having a respective depth greater than or equal to a second depth (d2). The second depth (d2) is strictly greater than the first depth (d1). The invention further relates to an associated manufacturing method.Figure for the abridged version: Fig 1.
