Abstract

A motor vehicle glazing prepared for installation is provided with one or more profiled spacers produced by extrusion of an extrudable polymer directly onto the glazing. A first spacer is provided along its outer periphery with an lip portion projecting beyond the peripheral area of the glazing. In the installed position of the glazing the lip portion rests against the window frame flange running parallel to the peripheral area of the glazing and acts, upon insertion of the glazing and during the setting process of the assembly adhesive, as a support and centering element for the glazing. Adjacent the first profiled spacer, and attached to the glazing is the assembly adhesive bead. Optionally, a second spacer is provided also adjacent the adhesive bead for retaining the adhesive bead between the first and second spacers and for adding support.

Claims

1. A window, comprising:

a glazing having a weight;

a peripheral sheet metal bracket oriented parallel to at least one edge of the glazing;

a first spacer attached to one surface of the glazing proximate to a peripheral edge thereof and adjacent the bracket for supporting the weight of the glazing, the first spacer being provided with means for centering and aligning the glazing upon the bracket including at least one peripheral portion having a cross-sectional configuration and a support surface for contacting the bracket, and means operatively associated with the bracket for aligning the glazing at a predetermined uniform distance away from said bracket; and

a bead of adhesive positioned adjacent said glazing edge periphery for securing the glazing to the bracket.

2. The window of claim 1 wherein the centering means comprises a lip portion which is oriented essentially parallel to the glazing surface and extends beyond the edge of the glazing.

3. The window of claim 2 wherein the first spacer lip portion has a length which is sufficient to prevent the glazing edge from contacting the bracket.

4. The window of claim 2 wherein the first spacer and lip portion are formed by extrusion of an elastomer, and are mounted upon an enamel layer on the glazing.

5. The window of claim 4 wherein the bead of adhesive is mounted upon the enamel layer.

6. The window of claim 5 further comprising a second spacer adjacent said adhesive bead for retaining said adhesive bead between said first and second spacers.

7. The window of claim 6 wherein said second spacer is formed by extrusion of an elastomer, and is mounted upon said enamel layer.

8. The window of claim 1 wherein the alignment means comprises a rounded top portion of said first spacer which contacts the bracket to support the glazing at said predetermined distance therefrom.

9. A window, comprising:

a glazing having a weight;

a peripheral sheet metal bracket attached to a support and oriented parallel to at least one edge of the glazing;

a first spacer attached to one surface of the glazing proximate to a peripheral edge thereof and adjacent the bracket for supporting the weight of the glazing, the first spacer being provided with means for centering and aligning the glazing upon the bracket including at least one peripheral portion having a cross-sectional configuration and a support surface for contacting the bracket to provide a force for centering the glazing upon the bracket, the first spacer peripheral portion further comprising a lip portion initially oriented essentially parallel to the glazing surface and extending beyond the edge of the glazing, the lip portion resiliently bending and contacting the bracket when the glazing is placed thereupon to provide the centering force, and means operatively associated with the bracket for aligning the glazing at a predetermined uniform distance away from the bracket; and

a bead of adhesive positioned adjacent to said glazing edge periphery for securing the glazing to the bracket.

10. The window of claim 9 wherein the first spacer lip portion has a length which is sufficient to prevent the glazing edge from contacting the bracket.

11. The window of claim 10 wherein the spacer and lip portion are formed by extrusion of an elastomer, and are mounted upon an enamel layer on the glazing.

12. The window of claim 11 wherein the bead of adhesive is mounted upon the enamel layer.

13. The window of claim 12 further comprising a second spacer adjacent to said adhesive head for retaining said adhesive bead between said first and second spacers.

14. The window of claim 13 wherein said second spacer is formed by extrusion of an elastomer, and is mounted upon said enamel layer.

15. The window of claim 9 wherein the alignment means comprises a rounded top portion of said first spacer which contacts the bracket to support the glazing at said predetermined distance therefrom.

16. A window, comprising:

a glazing having a weight;

a peripheral sheet metal bracket attached to a support and oriented parallel to at least one edge of the glazing;

a first spacer attached to one surface of the glazing proximate to a peripheral edge thereof and adjacent the bracket for supporting the weight of the glazing, the first spacer being provided with means for centering and aligning the glazing upon the bracket including at least one peripheral portion having a cross-sectional configuration and a support surface for contacting the bracket to provide a force for centering the glazing upon the bracket, said first spacer peripheral portion including a lip portion which is initially oriented essentially parallel to the glazing surface and extending beyond the edge of the glazing for resiliently bending and contacting the bracket when the glazing is placed thereupon to provide the centering force and means operatively associated with the bracket for aligning the glazing at a predetermined distance away from the bracket;

a bead of adhesive positioned adjacent said glazing edge periphery for securing the glazing to the bracket; and

a second spacer separate and spaced from said first spacer and adjacent said adhesive bead for contacting the bracket to assist in the alignment of the glazing upon the bracket and for retaining said adhesive bead between said first and second spacers.

17. The window of claim 16 wherein the first spacer lip portion has a length which is sufficient to prevent the glazing edge from contacting the bracket.

18. The window of claim 17 wherein said first and second spacers and said lip portion are formed by extrusion of an elastomer, and are mounted upon an enamel layer on the glazing.

19. The window of claim 18 wherein said bead of adhesive is mounted upon the enamel layer.

20. The window of claim 16 wherein the alignment means comprises a rounded top portion of said first spacer which contacts the bracket to support the glazing at said predetermined distance therefrom.
