  • Patent number: 10434844
    Abstract: A window assembly for a vehicle includes a plurality of window panels arranged with at least one pair of adjacent window panels, with adjacent edge portions of adjacent ones of the window panels joined by a respective molded joining element. The adjacent edge portions joined by a respective molded joining element are offset or non-coplanar. The molded joining element may comprise an encapsulation that at least partially receives a perimeter edge portion of at least one of the adjacent window panels. The molded joining element may at least partially receive a rear perimeter edge portion of a forward window panel and may not overlap an outer surface of the forward window panel, with the molded joining element at least partially receiving a front perimeter edge portion of a rearward window panel.

  • Publication number: 20190217692
    Abstract: A method for making a slider window assembly for a vehicle includes providing at least one fixed window panel and a movable window panel. A perimeter seal is disposed at least at a surface of the fixed window panel and includes a continuous sealing element that circumscribes an opening of the fixed window panel and that is configured to seal against the movable window panel about a periphery of the movable window panel when the movable window panel is closed. The perimeter seal includes a sealing tab at a corner region of the perimeter seal where an upper sealing portion is joined with a first elongated side sealing portion. The sealing tab is established at an elongated sealing lip of the upper sealing portion or of the first elongated side sealing portion. The sealing tab extends from the elongated sealing lip toward the surface of the fixed window panel.

  • Patent number: 10239397
    Abstract: A slider window assembly for a vehicle includes at least one fixed window panel and a movable window panel. A perimeter seal is disposed at a surface of the fixed window panel and includes a continuous sealing element that circumscribes an opening of the fixed window panel and that is configured to substantially seal against a surface of the movable window panel about a periphery of the movable window panel when the movable window panel is closed. The perimeter seal includes a sealing tab at a corner region of the perimeter seal where an upper sealing portion engages a first elongated side sealing portion. The sealing tab is joined with an elongated sealing lip of the upper sealing portion or the first elongated side sealing portion. The sealing tab extends from the elongated sealing lip toward the surface of the at least one fixed window panel.

  • Publication number: 20180227986
    Abstract: A rear slider window assembly for a vehicle includes a fixed window panel and a movable window panel that is movable between a closed position and an opened position. The movable window panel includes a laminated movable window panel having an electrical element disposed between an inner glass panel and an outer glass panel. The first electrical element is in electrical connection with a wire harness of the vehicle via a flexible connector electrically connected to a first electrical connector at an inner surface of the movable window panel and to a second electrical connector at the inner surface of the fixed window panel. The first electrical connector is electrically connected to the first electrical element via a thin flat connector that extends from the first electrical connector and wraps around a perimeter edge of the inner glass panel of the movable window panel.

  • Patent number: 10023026
    Abstract: A slider window assembly for a vehicle includes at least one fixed window panel and a frame portion attached at the at least one fixed window panel. A movable window panel is movable along upper and lower rails of the frame portion and movable between a closed position and an opened position. At least one of the upper and lower rails includes a recess for receiving adhesive therein and a tapered end region at an end of the recess. The tapered end region includes at least one notch or groove through a wall that at least partially circumscribes the recess, with the notch or groove configured to allow excess adhesive to escape during the adhesive bonding of the at least one of the upper and lower rails to the at least one fixed window panel. The tapered end region has an outer tapered surface opposite the recess.

  • Patent number: 10011158
    Abstract: A method of forming a unitary perimeter seal for attachment at a fixed window panel of a slider window assembly of a vehicle includes forming upper, lower and side sealing portions each having elongated body portions and sealing lips extending substantially therealong. The upper and lower sealing portion are arranged with first ends adjacent a respective end of a first side sealing portion and second ends adjacent a respective end of a second side sealing portion. The sealing portions are arranged so as to result in a perimeter frame that circumscribes an opening for the slider window assembly. Corner regions are molded at and partially over adjacent ends of the elongated body portions of the sealing portions, such that the corner regions include a curved sealing lip that provides a transition between the sealing lips of the adjacent ends of the sealing portions.
