Abstract

An automobile glass pane, intended for glueing to the fixing web of the window frame of an automobile body, is furnished along its edge with a profile strand of a hardened adhesive compound. This profile strand forms a no longer plastically deformable intermediate body between the glass pane and the adhesive strand. The profile strand is substantially of U-section and possesses anchorage projections. These anchorage projections produce a form-fitting and force-transmitting connection between the adhesive strand and the profile strand. They can additionally serve for the clamping fixing of different lugs, clips or profile strips.

Claims

1. A glass pane assembly bonded to a fixing web of a window, comprising:

a glass pane;

a hardened plastic profile strand adhered to an edge portion of said pane, said profile strand having a U-shaped cross-section with flanges defining a channel shaped cavity, said flanges having anchorage projections oriented towards one another to define cut back zone with increased width as compared to a spacing between said projections; and

a hardened adhesive strand filling said channel and adhering to the fixing web of the window opening,

whereby said hardened plastic profile strand and said adhesive strand are united by a form-fitting mechanical connection resulting from the width of the cut back zones being greater than the spacing between said projections.

2. The assembly of claim 1 wherein said anchorage projections are at ends of said flanges.

3. The assembly of claim 2 wherein said profile strand includes a central web connecting said flanges and a rib extending into said cavity from said central web, said rib including anchorage projections oriented towards said anchorage projections of said flanges.

4. The assembly of claim 2 wherein said profile strand is adhered to said pane by an adhesive.

5. The assembly of claim 2 wherein said profile strand is formed of an extruded adhesive compound applied to said pane when in an unhardened state.

6. The assembly of claim 2 including an adhesion reducing agent applied to surfaces of said profile strand to which said adhesive strand is adhered.

7. The assembly of claim 2 including at least one plastically deformable fixing lug each having a rigid clamping portion fitted in said cavity and forming a force transmitting and form fitting connection with said profile strand, and a deformable tongue portion.

8. The assembly of claim 2 including at least one fixing clip each having a clamping portion fitted in said cavity and forming a force transmitting and form fitting connection with said profile strand, a crank portion and a fixing bolt connection with the fixing web of the window opening.

9. The assembly of claim 2 including a frame-shaped decorative strip having an end portion fitted in said cavity and forming a force transmitting and form fitting connection with said profile strand and a portion surrounding the edge of said pane.

10. The assembly of claim 2 including at least one L-section profile strip having an end portion fitted in said cavity and forming a force transmitting and form fitting connection with said profile strand and a flange extending parallel to the edge of said pane to define an insertion groove, and a push in decorative profile insertable in said insertion groove.

11. The assembly of claim 2 including at least one fixing clip having an end portion fitted in said cavity and forming a force transmitting and form fitting connection with said profile strand and a portion extending parallel to the edge of said pane and having a folded over end portion to define an insertion groove, and a push in decorative profile insertable in said insertion groove.

12. The assembly of claim 2 wherein said profile strand is made from a moisture hardening, single compound polyurethane composition.

13. The assembly of claim 2 wherein said profile strand is made from a two component reaction mixture which reacts to produce a polyurethane.
