Abstract

A slider window assembly for a vehicle includes a frame portion having an upper rail and a lower rail, with at least one fixed window panel fixed relative to the frame portion and defining an opening. A movable window panel is movable along the upper and lower rails between a closed position and an opened position. A perimeter seal is disposed at the at least one fixed window panel. The perimeter seal includes a single continuous sealing element that circumscribes the opening 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 in its closed position.

a perimeter seal disposed at said at least one fixed window panel, wherein said perimeter seal comprises a single continuous sealing element that circumscribes said opening and that is configured to substantially seal against a surface of said movable window panel about a periphery of said movable window panel when said movable window panel is in its closed position;

wherein said perimeter seal comprises an elongated upper sealing portion, an elongated lower sealing portion, a first elongated side sealing portion and a second elongated side sealing portion, and wherein corner sealing portions are established between adjacent ends of said elongated sealing portions;

wherein said elongated upper sealing portion, said elongated lower sealing portion, said first elongated side sealing portion and said second elongated side sealing portion are separately formed from one another;

wherein said corner sealing portions are molded at said adjacent ends of said separately formed elongated sealing portions to join the separately formed elongated sealing portions and to provide a continuous sealing lip between sealing lips of the joined adjacent elongated sealing portions;

wherein said corner sealing portions comprise a body portion that is molded partially over body portions of adjacent elongated sealing portions to join and retain said elongated sealing portions relative to one another; and

wherein said continuous sealing lip of at least some of said corner sealing portions extends from the respective body portion and comprises an arcuate shaped sealing lip providing a curved transition between said sealing lips of the adjacent elongated sealing portions.

2. The slider window assembly of claim 1, wherein said elongated upper sealing portion, said elongated lower sealing portion, said first elongated side sealing portion and said second elongated side sealing portion comprise extruded sealing portions.

3. The slider window assembly of claim 1, wherein one of said elongated sealing portions comprises a Y-shaped sealing lip having an outer lip and an inner lip closer to said opening than said outer lip, and wherein said continuous sealing lip of said corner sealing portions at opposite ends of said one of said elongated sealing portions comprises an arcuate shaped single sealing lip that provides a curved transition between said inner lip of said Y-shaped sealing lip and another sealing lip of an adjacent elongated sealing portion that is adjacent to a respective one of the ends of said one of said elongated sealing portions.

4. The slider window assembly of claim 3, wherein said inner lip of said Y-shaped sealing lip is truncated so as to not extend to the ends of said one of said elongated body portions, and wherein said curved sealing lips of said corner sealing portions provide a continuous sealing lip between truncated ends of said inner sealing lip and respective ends of the adjacent elongated sealing portions.

5. The slider window assembly of claim 1, wherein one of said elongated sealing portions comprises a double sealing lip having an outer lip and an inner lip closer to said opening than said outer lip, and wherein said continuous sealing lip of said corner sealing portions at opposite ends of said one of said elongated sealing portions comprises an arcuate shaped single sealing lip that provides a curved transition between said inner lip of said double sealing lip and another sealing lip of an adjacent elongated sealing portion that is adjacent to a respective one of the ends of said one of said elongated sealing portions.

6. The slider window assembly of claim 1, wherein said each of said elongated sealing portions comprises an elongated body and a sealing lip extending substantially along said elongated body, and wherein said sealing lip is truncated so as to not extend to the ends of said elongated body, and wherein said corner sealing portions are established at said adjacent ends of said elongated sealing portions to provide a continuous sealing lip between truncated sealing lips of the adjacent elongated sealing portions.

7. The slider window assembly of claim 1, wherein said at least one fixed window panel comprises a single fixed window panel having said opening therethrough.

8. The slider window assembly of claim 7, wherein said perimeter seal is adhesively attached at a surface of said single fixed window panel around said opening.

9. The slider window assembly of claim 1, wherein said at least one fixed window panel comprises first and second fixed window panels defining said opening therebetween.

10. The slider window assembly of claim 9, wherein said perimeter seal is adhesively attached at respective surfaces of said first and second fixed window panels and at respective surfaces of upper and lower appliqué

s so as to be attached around said opening.

11. A slider window assembly for a vehicle, said slider window assembly comprising:

a frame portion having an upper rail and a lower rail;

at least one fixed window panel that is fixed relative to said frame portion, said at least one fixed window panel defining an opening;

a movable window panel that is movable along said upper rail and said lower rail, wherein said movable window panel is movable between a closed position, where said movable window panel is disposed at said opening, and an opened position, where said movable window panel is disposed at least partially along said at least one fixed window panel;

a perimeter seal disposed at said at least one fixed window panel, wherein said perimeter seal comprises a single continuous sealing element that circumscribes said opening and that is configured to substantially seal against a surface of said movable window panel about a periphery of said movable window panel when said movable window panel is in its closed position;

wherein said perimeter seal comprises an elongated upper sealing portion, an elongated lower sealing portion, a first elongated side sealing portion and a second elongated side sealing portion;

wherein said elongated upper sealing portion, said elongated lower sealing portion, said first elongated side sealing portion and said second elongated side sealing portion comprise respective elongated body portions and sealing lips that extend substantially along said body portions;

wherein said elongated upper sealing portion, said elongated lower sealing portion, said first elongated side sealing portion and said second elongated side sealing portion are separately formed from one another;

wherein said perimeter seal comprises corner sealing portions established between adjacent ends of the separately formed elongated sealing portions to join the separately formed elongated sealing portions;

wherein each of said corner sealing portions comprises a body portion that is molded partially over said body portions of respective adjacent elongated sealing portions to join and retain the respective elongated sealing portions relative to one another; and

wherein each of said corner sealing portions comprises a curved sealing lip that extends from said body portion and that extends between ends of said sealing lips of the respective adjacent elongated sealing portions joined by said corner sealing portion to provide a continuous sealing lip between said sealing lips of the respective adjacent elongated sealing portions.

12. The slider window assembly of claim 11, wherein said corner sealing portions are molded at said adjacent ends of the elongated sealing portions.

13. The slider window assembly of claim 11, wherein said sealing lips of the elongated sealing portions are truncated so as to not extend to the ends of said elongated body portions, and wherein said curved sealing lips of said corner sealing portions provide a continuous sealing lip between truncated ends of said sealing lips of the adjacent elongated sealing portions.
