Abstract

L'invention porte sur un arrangement de poignée, sur un appareil pouvant être saisi à la main, en un matériau plus souple que le matériau d'un corps de base de l'arrangement de poignée, servant de surface de saisie. Il est proposé de rapporter le matériau plus souple à un corps en matériau plastique coulé par injection, qui est fabriqué dans le cadre d'un procédé de coulée par injection bicomposant, en un matériau à stabilité de forme servant de support, le matériau souple servant de couche de couverture. Le corps de saisie est fixé au corps de base par une liaison avec complémentarité de forme, par l'intermédiaire d'une première et d'une deuxième structure de liaison correspondante rapportées respectivement au corps de base et au support.
