  • Patent number: 4631865
    Abstract: A window assembly for a motor vehicle door wherein the outer surface of the window and the outer surface of the door frame are substantially flush with each other. The assembly includes a window pane with at least one bracket secured to the outer surface of an end of the pane and projecting outwardly from that end in a direction substantially parallel to the surface of the glass. The assembly also includes a door frame having a vertically positioned guide portion with a guide groove open in the direction of the window pane. A slide piece is secured to the end of the bracket opposite the end secured to the pane and is slidably engaged within the guide groove so that the outer surface of the guide portion is substantially flush with the window pane and the window pane is guided in the vertical direction. Finally, there is a weather strip between the window pane and the door frame which is positioned at the vehicle compartment side of the guide portion.

  • Patent number: 4608778
    Abstract: A door window regulator for vertically moving a door window glass of a vehicle includes a guide member and a slider which is secured to the door window glass and guided by the guide member. A wire is stretched between upper and lower pulleys respectively disposed at the upper and lower portions of the guide member and is connected at its intermediate portion to the door window glass. Thus, the door window glass is vertically moved by the driving force derived from a wire driving unit. A wire guide shoe projects from the guide member such as to contact the portion of the wire between the upper and lower pulleys, whereby the wire is bent between the upper and lower pulleys to thereby reduce the space occupied by this door window regulator.

  • Patent number: 4607456
    Abstract: A door window regulator for vertically moving a door window glass of a vehicle includes a guide member which guides the vertical movement of the door window glass. A wire is stretched between pulleys respectively provided at the upper and lower portions of the guide member and is connected to the lower portion of the window glass, whereby the window glass is vertically moved by the driving force transmitted from a driving unit. The axis of either one of the pulleys extends in the direction substantially orthogonal to the plane which includes the portion of the wire which extends from that pulley to the driving unit and is directed toward the inside of the compartment of the vehicle, whereby the condition in which the wire is passed over the pulley is maintained in an appropriate state at all times.

  • Patent number: 4604829
    Abstract: A door window regulator for vertically moving a door window glass of a vehicle includes sliders secured to the door window glass. The sliders are respectively guided by a pair of guide members. The sliders are further respectively connected to portions of a wire which are respectively stretched along the guide members. The wire has a portion thereof wound on a driving unit. The wire is covered with wire tubes respectively disposed between the driving unit and each of the guide members and between the guide members. The wire tubes interconnect the various members, thereby making the regulator convenient for conveyance.

  • Patent number: 4597223
    Abstract: A door window regulator for vertically moving a door window glass of a vehicle includes a pair of guide members which guide respective sliders secured to the door window glass. Each of the sliders is connected to the portion of a wire which is stretched along each of the guide members. A portion of the wire is wound on a driving unit. A pair of glass brackets are provided such as to respectively correspond to the guide members and secured to the window glass to retain the associated slider. Each of the glass brackets is provided with a holder which clamps the wire. Each of the holders and the associated glass bracket are permitted to move relative to each other, whereby it is possible for the position of the window glass to be adjusted in assembly.

  • Patent number: 4571886
    Abstract: A window assembly for a motor vehicle door which includes a window pane having a window piece secured to one end. The window piece has a slide portion at a forward end offset toward the interior of the vehicle and is substantially crank-shaped in cross-section. A seal member is disposed on the side of the door frame and is in contact with the slide portion of the window piece on opposite sides thereof in a direction lateral to the window pane so the slide portion is slidable in the direction of opening or closing of the window pane. The seal member forms a seal between the door frame and the window piece. A sliding piece projects inwardly toward the interior of the vehicle and is secured to the window pane at a position closer to the center of the window pane than the window piece. A guide is formed on the door frame for guiding the sliding piece in the direction of opening or closing of the window pane and for regulating the lateral position of the window pane at a point through the sliding piece.
