Abstract

The seal and guide includes two portions which are connected by an elastomeric hinge. One of the portions is a fixation member which attaches to the flange on the frame of an automobile. The other portion includes a guiding and sealing channel which receives a movable window. Due to the elastomeric hinge, the guiding and sealing channel is allowed to flex so as to compensate for irregularities in the shape of the door frame. In this manner, the window may be easily moved and properly sealed on a variety of door frames.

Claims

1. A structure for guiding and sealing a movable window, comprising:

a first portion having a core and having means including a U-shaped clamping portion for connection to a frame of an automotive door;

a second portion having a core, and having means comprising a U-shaped guiding portion which opens oppositely to said U-shaped clamping portion for guiding and sealing a movable window of an automobile, said U-shaped guiding portion having an outer retaining wall connected to a web forming the bight of said U-shaped guiding portion, said outer retaining wall forming the leg of the U-shaped guiding portion farthest from said U-shaped clamping portion, said web having a window sliding portion adjacent said outer retaining wall; and

an elastomeric connection between said first portion and said second portion to provide limited hinge-like flexing movement between said first and second portions, said outer retaining wall being outside said window sliding portion and said elastomeric connection being inside said window sliding portion intermediate said U-shaped clamping portion and said window sliding portion.

2. A structure according to claim 1 wherein said elastomeric connection comprises an elastomeric material bonded to said first portion and bonded to said second portion.

3. A structure according to claim 2 wherein said first portion further includes a licker member having at least one sealing lip extending toward said second portion.

4. A structure according to claim 3 wherein said first portion includes a further U-shaped portion clamping said licker member in place, said further U-shaped portion being inverted with respect to said U-shaped clamping portion.

5. A structure according to claim 3 wherein said licker has two sealing lips.

6. A structure according to claim 1 further including sealing lips extending away from the first and second portions to seal against said frame.

7. A structure according to claim 1 wherein said rigid core of said first portion and said rigid core of said second portion comprise aluminum.

8. In combination with an apparatus for supporting a movable window for movement along a path in said frame, a structure for guiding and sealing said movable window, comprising:

a first portion having a core and having a Ushaped clamping portion clamped to said frame;

a second portion having a core, and having means comprising a U-shaped guiding portion which opens oppositely to said U-shaped clamping portion for guiding and sealing said movable window, said U-shaped guiding portion having an outer retaining wall connected to a web forming the bight of said U-shaped guiding portion, said outer retaining wall forming the leg of the U-shaped guiding portion farthest from said U-shaped clamping portion a portion of said web adjacent said outer wall extending along said movable window path; and

an elastomeric connection providing limited hinge-like flexing movement between said first and second portions, said outer retaining wall being outside said movable window path and said elastomeric connection being inside said movable window path intermediate said U-shaped clamping portion and said window sliding portion.

9. A method of manufacturing a structure for guiding and sealing movable windows, comprising:

forming a carrier having at least two U-shaped portions;

covering said carrier with an elastomeric material; and

cutting said carrier after said covering of said carrier in order to separate said carrier into sections, one of said section including said first U-shaped portion and the other of said sections including the other of said U-shaped portions, said sections remaining connected by said elastomeric material.

10. A method according to claim 9, wherein said step of forming a carrier comprises forming said carrier such that said two U-shaped portions have side by side walls interconnected by a web, and said step of cutting said carrier comprises removing said web.

11. A method according to claim 9 wherein said step of covering said carrier comprises bonding said elastomeric material to said carrier.

12. A method according to claim 9 wherein said step of forming a carrier comprises forming said carrier from aluminum.

13. A method according to claim 9 wherein said step of covering said carrier includes forming sealing lips of said elastomeric material.

14. A method according to claim 9 wherein the step of forming a carrier includes forming a third U-shaped portion having a wall common with a wall of one of said first mentioned U-shaped portions and opening in a direction opposite to a direction of opening of said one of said first mentioned U-shaped portion.
