Insert for overmolding in seat or cushion, has core with downward extending anchorage elements, upward extending ramps and magnetisable material on upper surface. A piece to be overmolded has a core with anchorage elements extending from its lower side and two ramps extending upwards from its opposite ends. Magnetisable material is attached to the upper surface of the core. In use the core is placed between two walls in the bottom of a mold so the ramps rest on the walls. The core is held in place by a magnet located between the walls and in the base of the mold. The molding material is sufficiently rigid that the angle of the ramps remains constant. Independent claims are included for the following: (a) a molded article includes an overmolded piece as above whose anchorage elements and the lower faces of its ramps are not overmolded; and (b) forming an article as in (a). |
