Definitions

• the present invention relates to a glazing, and in particular a vehicle glazing, comprising a glazed element, forming a separation between an exterior space and an interior space, and comprising a profiled bead having, seen in cross section, a base which is located in contact with one face of said glazed element.
• the base of the profiled bead can have a relatively high thickness, of at least 5 mm, considered from the face of the glazed element to which the profiled bead is fixed.
• a thickness is difficult to achieve by molding techniques.
• a first solution consists in providing an insert, generally made of plastic material, inside the base so that it occupies part of the volume of the profiled bead, but this is a complex and costly technique because it can generate a large number of non-compliant glazing.
• a second solution consists in making the material of the base so that it incorporates a foaming agent.
• a glazing may comprise a cover piece comprising a cover sole extending substantially parallel to said base and further to the outside than said base, but the mechanical attachment or the chemical fixing of this cover piece with a thick base, with a thickness of at least 5 mm, is difficult to produce and to control industrially.
• the object of the present invention is thus to remedy the drawbacks of the prior art by proposing a simple and effective solution so that a profiled bead glazing having a thick base can comprise a covering part further outside than this thick base.
• the inventors have discovered that, surprisingly, even if the density of a base whose material incorporates a foaming agent is lower, it was possible to effectively glue a cover piece on this thick base, then even the presence of the foaming agent is likely to affect or does affect the normally smooth surface of the base.
• Fixing the cover piece is thus extremely simple, while being very reliable and very compact.
• the present invention relates, in its broadest sense, to a glazing according to claim 1.
• This glazing comprises a glazed element providing a separation between an exterior space and an interior space, and comprising a profiled bead having, seen in cross section , a base which is located in contact with a face of said glazed element and which has a thickness of at least 5 mm from this face, said base of the profiled bead comprising a material incorporating a foaming agent, and this glazing is remarkable in that it comprises a cover piece comprising a cover sole extending substantially parallel to said base and more to the outside than said base, said cover piece adhering to said profiled bead with the aid of an adhesive layer interposed between a face of said cover sole and a face of said base.
• said profiled cord is based on, or made of, TPE.
• said cover piece adheres to said profiled cord only with the aid of an adhesive layer; there is no mechanical attachment of said cover piece to said profiled bead.
• said base of the profiled bead is based on, or made of, TPE.
• said base of the profiled bead does not include any filler or reinforcement; it comprises only the material which constitutes it.
• the thickness of said base may be 5.0 mm or more; it can be from 5.0 mm to 15.0 mm; it may be at least 5.5 mm, or even at least 6.0 mm.
• said base has a lower density of at least 5%, and preferably between 5% and 45%, or even between 10% and 35%; this low density is preferably measured relative to the density of another part of the profiled bead which is made of the same material as said base; this other part is preferably without foaming agent.
• said base of the profiled bead is located in contact with an outer face of said glazed element, and more preferably only in contact with an outer face of said glazed element.
• said base of the profiled bead is made of a material incorporating a foaming agent and more preferably the entire profiled bead is made of a material incorporating a foaming agent.
• a single material is used for the entire profiled bead, which is simpler but the foaming functionality is only realized in the base, which has a thickness and therefore a volume, adequate for this; there are no bubbles and a lower density than where the thickness is at least 5 mm.
• said glazed element is a fixed vehicle glazed element; it is not mobile relative to the vehicle that carries it.
• the present invention also relates to a method of manufacturing a glazing according to the invention, said glazing comprising a glazed element providing a separation between an exterior space and an interior space, and comprising a profiled bead having, seen in cross section, a base which is located in contact with a face of said glazed element and which has a thickness of at least 5 mm from this face, a foaming agent being integrated into said base of the profiled bead during the manufacture of said profiled bead by molding, said process being remarkable in that, after the manufacture of said profiled bead by molding, an adhesive layer is interposed between a face of said base and a face of a cover sole of a cover piece, said cover sole extending substantially parallel to said base and more to the outside than said base, in order to allow said cover piece to adhere to said profiled bead.
• the glazing according to the invention is particularly light because the base incorporating a foaming agent is lighter and the adhesive layer is also very light.
• the cover piece is fixed only by the adhesive layer; preferably, there is no other attachment means between the cover piece and the rest of the glazing.
• FIG. 1 illustrates a partial cross-sectional view of a glazing according to the invention
• FIG. 2 is a photograph of a cross-section of a base of a foaming agent shaped bead for practicing the invention.
• the present invention relates to a glazing 1, and in particular a vehicle glazing as visible in Figure 1.
• This glazing comprises a glazed element 2, fixed, forming a separation between an exterior space E and an interior space I and comprises a portion joint (or cord) profile 4 in a flexible polymer material which is located along a side edge of the fixed glazed element, this joint portion extending further laterally than the side edge.

• the sheet(s) of material may (or may) be mineral(s), in particular glass, or organic(s), in particular plastic.
• the glazed element When the glazed element is made of organic material, it was manufactured prior to the implementation of the invention by molding the constituent material of the glazed element in a molding device comprising a mold comprising at least one fixed part of mold and a movable mold part which is movable relative to the fixed mold part, said mold parts cooperating in the closed state of the mold, during the molding step, to form a mold cavity having in section the shape section of the glazed element.

• the glazed element is made of mineral material, it was manufactured prior to the implementation of the invention by melting mineral material into a flat sheet, then by cutting this sheet and possibly bending and/or tempering this sheet .

• the constituent polymer material of the profiled bead 4 can be a thermoplastic (PVC, TPE, etc.), a polyurethane or even a synthetic rubber of the EPDM type or any other suitable material.
• the profiled bead 4 is preferably manufactured by implementing a manufacturing process called "encapsulation” because it comprises a step of molding the profiled bead 4 in a molding device, between two molding elements, a molding receiving the inner face of the glazing and a molding element receiving the outer face of the glazing, these two molding elements being closed on one another during the molding step while producing between them a molding cavity which is filled with the constituent material of the profiled bead 4 during the step of molding this profiled bead.
