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.

First claim

The invention claimed is:

1. A slider window assembly for a vehicle, said slider window assembly comprising:
at least one fixed window panel, said at least one fixed window panel defining an opening;
an upper rail and a lower rail fixedly disposed at said at least one fixed window panel;
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 a surface of said at least one fixed window panel, wherein said perimeter seal comprises a continuous sealing element that circumscribes said opening and that is configured to seal against a surface of said movable window panel about a periphery of said movable window panel when said movable window panel is in the 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 said elongated sealing portions comprise respective elongated sealing lips; and
wherein said perimeter seal comprises a sealing tab at a corner region of said perimeter seal where said upper sealing portion engages said first elongated side sealing portion, and wherein said sealing tab is joined with at least one of said elongated sealing lip of said upper sealing portion and said elongated sealing lip of said first elongated side sealing portion, and wherein said sealing tab extends from said at least one of said elongated sealing lips toward said surface of said at least one fixed window panel.

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 said sealing tab is overmolded at said at least one of said elongated sealing lip of said upper sealing portion and said elongated sealing lip of said first elongated side sealing portion when said upper sealing portion and said first elongated side sealing portion are joined.

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

5. The slider window assembly of claim 4 , 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 appliqués so as to be attached around said opening.

6. The slider window assembly of claim 4 , wherein said upper rail comprises a rail attachment portion that attaches at said at least one fixed window panel and at an upper appliqué, and wherein said perimeter seal is adhesively attached at respective surfaces of said first and second fixed window panels and at said rail attachment portion at said upper appliqué.

7. The slider window assembly of claim 6 , wherein said rail attachment portion comprises a fixed panel attachment portion and a wider appliqué attachment portion, and wherein said wider appliqué attachment portion has a tapered end at where it overlays a portion of said fixed window panel, and wherein said upper sealing portion is configured to attach along said tapered end of said wider appliqué attachment portion.

8. The slider window assembly of claim 1 , wherein said at least one fixed window panel comprises a single fixed window panel having an opening therethrough, and 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 perimeter seal comprises another sealing tab at a corner region of said perimeter seal where said lower sealing portion engages said first elongated side sealing portion, and wherein said sealing tab is joined with at least one of an elongated sealing lip of said lower sealing portion and said elongated sealing lip of said first elongated side sealing portion, and wherein said sealing tab extends from said at least one of said elongated sealing lips toward said surface of said at least one fixed window panel.

10. The slider window assembly of claim 1 , wherein said first elongated side sealing portion comprises a double lip configuration for sealing against said movable window panel when said movable window panel is at least partially closed, and wherein said sealing tab at said first elongated side sealing portion is inboard of said double lip configuration and towards the opening of said at least one fixed window panel.
