  • Patent number: 6969038
    Abstract: A vehicle external mirror assembly (10) comprises three main parts: a vehicle-to-mirror assembly attachment bracket (15), a mirror housing (20) and a mirror (41). Housing (20) comprises a thin molded external plastic shell (50) and a foam core (21), the foam anchoring and supporting the shell. A load diffuser (45) may be positioned within foam (21) to reduce the maximum tensile and compressive stresses within the foam (21). Attachment bracket (15) is of a similar construction with a thin shell (15) internal foam (18) and load diffuser (16).

  • Patent number: 6849225
    Abstract: The present invention is a mould and a method of moulding a plastic component using the mould that enable the manufacturer of a moulded component (45) which has an external covering. The method of moulding comprises either locating a pre-formed component (41) into a first part of the mould or vacuum forming a thin film (40) into a mould cavity. A first mould part (15) has a mould cavity into which the pre-formed component (41) is placed or the thin film (40) is vacuumed formed into. The method continues by partly closing a second part of the mould (25) into the first part of the mould (15) and injecting molten plastic (34) onto the surface of the pre-formed component (41) or thin film (40). The second mould part (25) is then fully closed to force the molten plastic (34) to fill the resultant mould cavity (36). This bonds the molten plastic to either the pre-formed component (41) or the thin film (40) to form the final shape of the moulded component (45).
