Abstract

A window assembly for a vehicle includes a fixed frame having a pair of opposite side frame members, an upper frame member and a lower frame member. A fixed window panel is disposed at a lower portion of the side frame members and at the lower frame member. A movable window panel is movable relative to the fixed window panel and the frame between an opened position and a closed position. Each of the side frame members includes a lower channel for receiving a side perimeter edge region of the fixed window panel and an end region of the lower frame member. An elastomeric seal is overmolded along the lower channel of the side frame member and is configured to receive and seal against (i) the side perimeter edge region of the fixed window panel and (ii) the end region of the lower frame member.

First claim

1 . A vehicular window assembly, said vehicular window assembly comprising:
a frame configured to fixedly mount to a vehicle, said frame comprising a pair of opposite side frame members, an upper frame member and a lower frame member; a fixed window panel disposed at a lower portion of said side frame members and at said lower frame member; a movable window panel movably disposed at said side frame members and movable relative to said fixed window panel and said frame between an opened position and a closed position; wherein each of said side frame members includes a lower channel for receiving a respective side perimeter edge region of said fixed window panel and a respective end region of said lower frame member; an elastomeric seal overmolded along and in said lower channel of each of said side frame members; wherein said elastomeric seal comprises a sealing channel that receives and seals against (i) the respective side perimeter edge region of said fixed window panel and (ii) the respective end region of said lower frame member; and wherein a lower end portion of said sealing channel of said elastomeric seal that receives the respective end region of said lower frame member has a greater width dimension than the width dimension of the portion of said sealing channel that receives the respective side perimeter edge region of said fixed window panel.

2 . The vehicular window assembly of claim 1 , wherein said side frame members of said frame comprise polymeric members.

3 . The vehicular window assembly of claim 2 , wherein said side frame members comprise molded polymeric members formed via an injection molding process.

4 . The vehicular window assembly of claim 2 , wherein said side frame members and said elastomeric seal are molded via a two shot molding process that molds said side frame members in a first molding process and molds said elastomeric seal at said side frame members in a second molding process.

5 . The vehicular window assembly of claim 1 , wherein said elastomeric seal is retained at said lower channel of the respective side frame member via a portion of said elastomeric seal protruding through apertures formed through the respective side frame member at said lower channel.

6 . The vehicular window assembly of claim 1 , wherein a center frame member is disposed along an upper edge region of said fixed window panel, and wherein said sealing channel of said elastomeric seal of each of said side frame members is configured to receive and seal against a respective end region of said center frame member.

7 . The vehicular window assembly of claim 6 , wherein an upper portion of said sealing channel of said elastomeric seal that receives the respective end region of said upper frame member has a greater width dimension than the width dimension of the portion of said sealing channel that receives the respective side perimeter edge region of said fixed window panel.

8 . The vehicular window assembly of claim 1 , wherein said movable window panel is vertically movable relative to said frame and said fixed window panel when said vehicular window assembly is mounted at the vehicle.

9 . The vehicular window assembly of claim 1 , wherein said movable window panel is retainable in a selected one of a plurality of positions between the opened position and the closed position.

10 . The vehicular window assembly of claim 1 , wherein said movable window panel is circumscribed by a movable frame having opposite side frame portions and upper and lower frame portions.

11 . The vehicular window assembly of claim 10 , wherein a respective end of said upper frame portion of said movable frame is movably received in an upper channel of each of said side frame members.

12 . The vehicular window assembly of claim 11 , wherein said side frame portions of said movable frame are received in respective movable window channels of said side frame members, and wherein said movable window channels are parallel to said upper channels and said lower channels of said side frame members.

13 . The vehicular window assembly of claim 12 , wherein said upper channels of said side frame members comprise a plurality of stop elements that function to retain said movable window panel in a selected one of a plurality of positions between the opened position and the closed position.

14 . The vehicular window assembly of claim 1 , wherein said vehicular window assembly is configured to mount at a side of a bus.

15 . The vehicular window assembly of claim 1 , wherein said lower channel of each of said side frame members has a constant width dimension.

16 . A vehicular window assembly, said vehicular window assembly comprising:
a frame configured to fixedly mount to a vehicle, said frame comprising a pair of opposite side frame members, an upper frame member and a lower frame member; a fixed window panel disposed at a lower portion of said side frame members and at said lower frame member; a center frame member disposed along an upper edge region of said fixed window panel; a movable window panel circumscribed by a movable frame having opposite side frame portions and upper and lower frame portions, wherein said opposite side frame portions of said movable frame are movably disposed at said side frame members, and wherein said movable window panel and said movable frame are movable relative to said fixed window panel and said frame between an opened position and a closed position; wherein each of said side frame members includes a lower channel for receiving a respective side perimeter edge region of said fixed window panel and a respective end region of said lower frame member; wherein each of said side frame members includes a movable window channel parallel to and adjacent to said lower channel, and wherein each of said side frame portions of said movable frame are received in and are movable along the respective movable window channel; an elastomeric seal overmolded along and in said lower channel of each of said side frame members; wherein said elastomeric seal comprises a sealing channel that receives and seals against (i) the respective side perimeter edge region of said fixed window panel, (ii) the respective end region of said lower frame member and (iii) the respective end region of said center frame member; wherein a lower end portion of said sealing channel of said elastomeric seal that receives the respective end region of said lower frame member has a greater width dimension than the width dimension of the portion of said sealing channel that receives the respective side perimeter edge region of said fixed window panel; and wherein an upper end portion of said sealing channel of said elastomeric seal that receives the respective end region of said center frame member has a greater width dimension than the width dimension of the portion of said sealing channel that receives the respective side perimeter edge region of said fixed window panel.

17 . The vehicular window assembly of claim 16 , wherein said side frame members of said frame comprise polymeric members, and wherein said side frame members comprise molded polymeric members formed via an injection molding process.

18 . The vehicular window assembly of claim 17 , wherein said side frame members and said elastomeric seal are molded via a two shot molding process that molds said side frame members in a first molding process and molds said elastomeric seal at said side frame members in a second molding process.

19 . The vehicular window assembly of claim 16 , wherein said
