  • Patent number: 8186741
    Abstract: A mirror assembly includes a reflective element portion and a molded portion formed of a multi-void, lightweight structure. The multi-void, lightweight structure may be formed by injecting a gas into an injection mold while the molded portion is being molded, resulting in a multi-void aerated molded structure having multiple-voids introduced during the molding step. A window assembly for a vehicle may include an outer frame portion, an inner frame portion hingedly attached to the outer frame portion, and at least one sealing element established along a sealing portion of the outer and/or inner frame portions. The outer frame portion may be pivoted relative to the inner frame portion and about the hinge portions to a closed position. The outer frame portion may be connected to the inner frame portion when in the closed position to secure the at least one sealing element therebetween.

  • Publication number: 20020140251
    Abstract: A window assembly for a vehicle provides at least one fixed panel or window and a movable panel or window. A one piece frame is formed which includes a perimeter frame and at least one dividing member. The window panel assembly may be adapted for a vehicle door, whereby the fixed window panel is secured to the dividing member and a portion of the perimeter frame, while the movable window panel slidably engages a portion of the perimeter frame with one edge and the dividing member with the other edge, which is opposite the first edge. A rail or guide member is secured to the second edge of the movable panel for slidable engagement with the dividing member. The rail member and guide member allow the movable window panel and fixed window panel to form a substantially flush, continuous, planar surface across their adjacent edges, while still providing a substantially airtight seal therebetween.
