Abstract

L'invention concerne un procédé comprenant les étapes suivantes : prévoir une coiffe (3) comprenant un format (4) comprenant une couche de matériau de revêtement (5) et une sous-couche de mousse (6) ; prévoir une nappe (7) chauffante à base d'un réseau de filaments (8) conducteurs résistifs disposés en surface d'une feuille support (9) poreuse et isolante électriquement ; coller ladite nappe en envers de ladite sous-couche ; déposer sur ladite nappe un film dégradable (15) agencé pour éviter un enrobage desdits filaments par ladite mousse ; former un bloc (14) de rembourrage surmoulant ledit format par l'intermédiaire de ladite nappe.The invention relates to a method comprising the following steps: providing a cap (3) comprising a format (4) comprising a coating material layer (5) and a foam underlayer (6); providing a heating sheet (7) based on a network of resistive conductive filaments (8) arranged on the surface of a porous and electrically insulating support sheet (9); gluing said web on the reverse side of said sublayer; depositing on said web a degradable film (15) designed to prevent coating of said filaments by said foam; forming a padding block (14) overmolding said format by means of said web.
