Abstract

A pane arrangement including a pane, for example a vehicle windscreen, and a holding section joining an attachment part to the pane, the holding section connected in a first connecting strip, which runs parallel to an edge of the pane, to a surface of the pane by a self-adhesive tape, and connected in a second connecting strip, which also runs parallel to the edge of the pane, to a surface of the pane by an adhesive applied in a flowable state and having a greater hardness than the self-adhesive tape. The second connecting strip is arranged nearer the edge of the pane than the first connecting strip, and thereby the connection between the pane and the holding section is as stiff as possible and yet the pane arrangement can be produced quickly and without a high outlay.

Claims

1. A pane arrangement comprising:

a pane; and

a holding section that rejoins a water box cover to the pane, the holding section being connected to the pane via a first connecting strip and a second connecting strip,

wherein the first and second connecting strips extend longitudinally parallel to a longitudinal edge of the pane, the first connecting strip being a self-adhesive tape so as to connect to a surface of the pane, the second connecting strip being an adhesive applied in a fluid state so as to connect to the surface of the pane, and the adhesive of the second connecting strip having a greater hardness than the self-adhesive tape of the first connecting;

strip, and

wherein the second connecting strip is arranged nearer the edge of the pane than the first connecting strip.

2. The pane arrangement according to claim 1, wherein the self-adhesive tape includes a foamlike middle layer and two adhesive layers arranged on opposite visible surfaces of the tape, and

wherein the adhesive applied in the fluid state is a polyurethane (PU)-based adhesive, silicone, acrylates, hotmelt, or 2-component adhesive.

3. The pane arrangement according to claim 1, wherein the holding section includes at least one spacer in a region of the first and second connecting strips, the at least one spacer being connected integrally with the holding section and being in contact with the surface of the pane, and

wherein a height of the at least one, spacer defines a thickness of the layer of the adhesive of the second connecting strip.

4. The pane arrangement according to claim 3, wherein the holding section includes first and second strip-shaped or bead-shaped spacers that extend in a longitudinal direction of the connecting strips, the second strip-shaped or bead-shaped spacer being disposed raised within the second connecting strip, and the first strip-shaped or bead-shaped spacer forming an edge closure of the first connecting strip and the holding section.

5. The pane arrangement according to claim 1, wherein the holding section includes

a core, and

a coating surrounding the core, the coating made from plastic material which is a more flexible material than a material of the core, which is stiffer than the material of the coating, and

wherein the coating is applied by extrusion or injection molding around the core.

6. The pane arrangement according to claim 5, wherein the core consists of a metallic material, such as aluminium, stainless steel, titanium, spring steel, or structural steel.

7. The pane arrangement according to claim 5, wherein the holding section includes a clamping channel that is undercut in cross section and extends parallel to the edge of the pane.

8. The pane arrangement according to claim 7, wherein the holding section includes a limb that faces the edge of the pane and bounds the clamping channel, the limb including an end section made from an elastomeric material that is more flexible than the material of the coating, the end section being integrally formed with the holding section by coextrusion, and the end section touching an end face of the pane coming out from the edge of the pane, such that a free space remains between the limb with the end section and the end face of the pane.

9. The pane arrangement according to claim 5,

wherein the holding section further includes

a clamping channel that extends parallel to the edge of the pane, and

a limb that faces the edge of the pane and delimits an inside of the clamping channel, and

wherein the core includes

a first portion that extends through the holding section widthwise such that a first segment of the first portion of the core extends parallel to a plane of the surface of the pane and is disposed adjacent to the first and second connecting strips, and a second segment of the first portion of the core extends with a shape of the clamping channel, and

a second portion that extends through the limb of the holding section.

10. The pane arrangement according to claim 1, wherein the first connection strip abuts the second connecting strip on a lateral edge thereof.
