Abstract

L'invention concerne un procédé pour munir un volant de direction d'un enrobage sans joint, englobant la couronne du volant, les rayons du volant et la zone centrale pour un recouvrement par un airbag présentant des lignes de déchirure, cet enrobage étant constitué par un ensemble en matière plastique moulé d'une seule pièce par un processus de moulage ou d'injection, avec surface fermée et, éventuellement, corps de base en mousse. Le procédé est caractérisé en ce qu'on fixe sur la base centrale du squelette du volant, un noyau en un matériau à faible point de fusion, en ce qu'on place ensuite ledit squelette et le noyau dans un moule pour la formation de la pièce moulée en matière plastique, en ce qu'on fabrique ladite pièce moulée et en ce qu'après solidification de celle-ci, le noyau est porté à fusion par élévation de température et le matériau est évacué, sous forme liquide, de la pièce moulée en matière plastique.
