A window pane (1), in particular an automobile window pane, is adhesively bonded to a frame (8) of a window opening by an adhesive bead (6), and carries a profiled bead (3) provided with a recess (4) extending longitudinally and a tear-away cord (8) laid therein. Tear-away cord (8) is designed for breaking the adhesive bond between window pane (1) and frame (7). A contact surface is provided for adhesive bead (6) alongside profiled bead (3). In the fitted state, recess (4) is open toward adhesive bead (6) so that the tear-away cord may be pulled without exerting a high force directly in the adhesive bead that abuts the opening of the recess.

1. A window comprising:a pane; an adhesive bead; a profiled bead coupled to a surface of said pane and comprising a longitudinally extending recess; a tear-away cord configured and dimensioned for breaking an adhesive bond between said pane and a frame of a window opening, the tear-away cord being comprised in said recess; and a contact region defined as the region between said adhesive bead and said pane having a width bounded by said profiled bead; wherein said window is capable of being adhesively bonded to said frame of said window opening, and said recess is open toward the contact region. 2. The window of claim 1, wherein a portion of said profiled bead is covered by said adhesive bead and said recess is disposed adjacent said contact region.3. A window comprising;a pane; an adhesive bead; a profiled bead coupled to a surface of said pane and comprising a longitudinally extending recess; a tear-away cord configured and dimensioned for breaking an adhesive bond between said pane and a frame of a window opening, the tear-away cord being comprised in said recess; and a contact region defined as the region between said adhesive bead and said pane having a width bounded by said profiled bead; wherein said window is capable of being adhesively bonded to said frame of said window opening; said recess is open toward the contact region; a portion of said profiled bead is covered by said adhesive bead and said recess is disposed adjacent said contact region; and said portion of said profiled bead comprises a ramp extending from proximate the recess toward the surface of the pane. 4. The window of claim 1, wherein said profiled bead, said adhesive bead and said tear-away cord comprise materials that do not adhere to one another.5. The window of claim 1, wherein said profiled bead comprises a thermoplastic elastomer and said adhesive bead comprises a polyurethane.6. The window of claim 1, wherein said tear-away cord extends through the adhesive bead in at least one location to establish a purchase point.7. The window of claim 1, wherein said tear-away cord is completely enclosed between said profiled bead and said adhesive bead, and said adhesive bead is provided with at least one mark defining a location for positioning a purchase point on said tear-away cord.8. The window of claim 1, wherein said profiled bead further comprises an elastically deformable lip extending beyond an edge of said pane.9. The window of claim 1, wherein said profiled bead is formed in situ by extrusion or injection molding onto said pane.10. The window of claim 1, wherein said profiled bead is prefabricated and adhesively bonded to said pane.11. A window comprising:a pane; an adhesive bead; a profiled bead coupled to a surface of said pane and comprising a recess and a ramp extending from proximate the recess; and a tear-away cord comprised in said recess; wherein said adhesive bead covers said ramp and adheres to said pane. 12. The window of claim 11, wherein said adhesive bead does not adhere to said ramp.13. The window of claim 11, wherein said profiled bead is disposed proximate an edge of said pane.14. The window of claim 11, wherein said pane comprises glass.15. The window of claim 11, further comprising an opaque border strip disposed between said adhesive bead and said pane.16. The window of claim 15, wherein said strip comprises a baked material.17. The window of claim 11, further comprising a border strip disposed between said profiled bead and said pane.18. The window of claim 11, wherein said profiled bead comprises an extruded polymer.19. The window of claim 11, wherein said profiled bead comprises an injection molded polymer.20. The window of claim 11, wherein said profiled bead is prefabricated and adhesively bonded to said pane.21. The window of claim 11, wherein said pane comprises an outer edge and said recess opens in a direction away from said outer edge.22. The window of claim 11, wherein said pane comprises an outer edge and said profiled bead is disposed closer to said outer edge than said adhesive bead.23. The window of claim 11, wherein said tear-away cord contacts said adhesive bead.24. The window of claim 11, wherein said tear-away cord passes through said adhesive bead in at least one location.25. The window of claim 11, wherein said profiled bead comprises a thermoplastic elastomer.26. The window of claim 11, wherein said adhesive bead comprises polyurethane.27. The window of claim 11, wherein said recess comprises a reverse taper.28. The window of claim 11, wherein said profiled bead further comprises a lip.29. The window of claim 11, wherein said recess is completely covered by said adhesive bead.30.
