Abstract
Abstract A glass pane is furnished at the edge with a profile having a U-section clamping portion. The glass pane is also furnished, in the edge zone covered by the U-section clamping portion of the profile, with a facing firmly adhering to the glass surface and having a profiled surface. The U-shaped clamping portion of the profile possesses, on the surface bearing against the facing, a profiling corresponding to the profiling of the facing, in such a manner that a form-fitting connection is obtained between the arms of the U-section clamping portion and the profiled facing.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
135 words
A glass pane assembly comprising: a glass pane having an edge region; a facing firmly adhering to at least one surface of said edge region of said glass pane, said facing having a profiled surface and being formed of a hardened extrudable plastic material; and a profile element formed of an elastomeric material having an inherent resiliency, and having a U-shaped clamping portion, said clamping portion having profiling positioned on an inner surface of at least one arm of said U-shape, said profiled surface and said profiling having complementary shapes so as to mate with one another when said profile element is mounted on said glass pane, whereby a form fitting connection which resists separation may be obtained between said clamping portion and said profiled facing by pushing said profile element on said glass pane.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
30 words
Glass pane according to claim 1 wherein said profiled surface comprises at least one rib extending parallel to a glass pane edge and formed to approximately sawtooth shape in cross-section.
Claim 4
Dependent Claim
25 words
Glass pane according to claim 2 wherein said ribs form back-out zones against which corresponding projections of said profiling of said profile element respectively engage.
Claim 5
Dependent Claim
30 words
Glass pane according to claim 1 wherein said facing is formed of a polyurethane adhesive from the group consisting of a moisture-hardening, single-component polyurethane adhesive and a two-component polyurethane adhesive.
Claim 6
Dependent Claim
27 words
Glass pane according to claim 1 wherein said facing has a thickness of 0.5 to 2 mm and has a profile depth of 0.5 to 1.5 mm.
Claim 7
Dependent Claim
15 words
Glass pane according to claim 1 wherein said profile element is formed of a polymer.
Claim 8
Dependent Claim
23 words
Glass pane according to claim 6 wherein said profile element has a metal inlay which increases a clamping force of said clamping portion.
Claim 9
Dependent Claim
39 words
Glass pane according to claim 1 wherein said profile element comprises a profile frame furnished internally, on a central web thereof lying opposite to a peripheral surface of said glass pane with a recess for receiving a sealing compound.
Claim 10
Dependent Claim
26 words
Glass pane according to claim 1 wherein said profile element has a greater hardness in a region having said profiling than in the other regions thereof.
Claim 11
Dependent Claim
51 words
Glass pane according to claim 1 wherein said facing is extended towards a center of said glass pane, on the surface of said glass pane to be bonded with a mounting flange of a window frame of an automobile body, whereby an adhesive cord may be bonded to such extended facing.
