  • 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: 6010226
    Abstract: A vehicle mirror comprises a mirror case (20), an intermediate member (38), a base member (18) secured to a vehicle, and a mirror case pivot assembly (56, 72) at one end of the intermediate member (38) pivotally connecting the intermediate member (38) to the mirror case (20) for relative angular movement about a first pivot axis. First and second rigid link (26, 42) have opposite ends pivotally connected to the base member (10) and to the opposite end of the intermediate member (38). The pivotal connections (28, 44) at the ends of the first and second rigid links (26, 42) nearer to the front of the vehicle are more widely spaced from each other than the pivotal connections (40, 52) at the other ends of the first and second links (26, 42).
