Abstract

A spacer for installation along the upper or lower horizontal edge of a vehicle windshield. The spacer is used to maintain the support bracket at a predetermined distance and perpendicular to the surface of the windshield. The spacer includes a first surface for contact with the windshield edge, a second surface for contact with the bracket, and a support surface which works a support element fastened to the bracket for maintaining the bracket substantially perpendicular to the edge of the windshield. The windshield, equipped with the spacer, can thus be positioned by itself by simple alignment of the spacer on the bracket support element while an adhesive is applied between the windshield and bracket and cures without further support.

Claims

1. A vehicle window comprising a glazing;

a peripheral sheet metal bracket attached to a vehicle and oriented parallel to the edges of the glazing, said bracket including a support element attached thereto; and

a spacer attached to the periphery of the glazing on at least one edge adjacent the bracket for supporting the weight of the glazing and for maintaining the bracket at a predetermined uniform distance away from said glazing, said spacer being provided with a lower peripheral portion having a recess with a cross sectional configuration forming a support surface for contacting said support element on said bracket, said support element being positioned within said recess at an inclined angle so that, as the glazing is positioned on the bracket, the support surface of the spacer contacts the support element and the weight of the glazing exerts a force which directs the glazing toward the bracket.

2. The window according to claim 1, wherein said support element is made by the deformation of an end of the bracket oriented toward the glazing.

3. The window according to claim 1, wherein the support element comprises an inverted angle or hook fastened to the bracket.

4. The window according to claim 1 wherein the spacer comprises a second peripheral portion extending along the edge of the glazing whose length and position on the glazing are defined such that it rests, optionally by elastic deformation, in continuous contact with the edge of the bracket.

5. The window according to claim 4, wherein said second peripheral portion includes a groove.

6. The window according to claim 1 wherein the bracket further comprises a second support element, said support elements forming a channel for surrounding the peripheral portion of the spacer.

7. The window of claim 6 wherein the peripheral portion of the spacer has a bulbous shape which substantially fills the channel of the bracket.

8. The window according to claim 1, wherein the spacer further comprises means for receiving a shear cord.

9. The window according to claim 1, wherein the spacer is obtained by extrusion and subsequent curing of a viscous adhesive compound directly onto the surface of the glass.

10. The window of claim 1 wherein the support element forms an angle of inclination of less than 90°

with respect to the bracket.

11. The window of claim 1 wherein the glazing includes a coating along its edge beneath the spacer.

12. The window of claim 1 wherein the bracket includes two layers of metal and the support element is formed from the metal layer closest to the spacer, thus leaving an opening in said closest metal layer for reception of an adhesive.

13. The window of claim 1 wherein said support element is made from a separate member which is attached to and forms part of said bracket.

14. The window of claim 1 wherein said spacer and bracket form an enclosure for an adhesive.

15. The window of claim 14 wherein said spacer includes a second peripheral portion having a lip portion which engages the lower end of said bracket.

16. The window of claim 1 further comprising a bead of adhesive for joining said glazing to said bracket.

17. A vehicle window comprising a glazing;

a peripheral sheet metal bracket attached to a vehicle and oriented parallel to the edges of the glazing, said bracket including a support element attached thereto and extending the length of said bracket;

a coating along the edge of said glazing opposite said bracket;

a spacer attached to the periphery of the glazing on at least one edge adjacent the bracket for supporting the glazing and for maintaining the bracket at a predetermined uniform distance away from said glazing, said spacer being provided with a lower peripheral portion having a recess with a cross sectional configuration forming a support surface for contacting said support element on said bracket, said support element being positioned within said recess at an inclined angle; and

a bead of adhesive for joining said bracket and glazing.

18. The window of claim 17 wherein the support element forms an angle of inclination of less than 90°

with respect to the bracket.

19. A vehicle window comprising a glazing;

a peripheral sheet metal bracket attached to a vehicle and oriented parallel to the edges of the glazing, said bracket including a support element attached thereto and extending the length of the bracket;

a coating along the edge of said glazing opposite said bracket;

a spacer attached to the periphery of the glazing on at least one edge adjacent the bracket for supporting the weight of the glazing and for maintaining the bracket at a predetermined uniform distance away from said glazing, said spacer being provided with a lower peripheral portion having a recess with a cross sectional configuration forming a support surface for contacting said support element on said bracket said support element being positioned within said recess at an inclined angle; and

a bead of adhesive for joining said bracket and glazing, said support element extending along a portion of said bracket, and said spacer including a second peripheral portion having a lip portion which engages the lower edge of said bracket, and a third portion which contacts said glazing coating and connects said spacer peripheral portions.

20. The window of claim 19 wherein the support element forms and angle of inclination of less than 90°

with respect to the bracket.
