Abstract
Abstract For qualitatively and functionally improving the connection of a glass pane (K) to a load bearing structure (SR) of a polymeric material, especially a car body element structure for motor vehicles such as a door and the like, a preliminary attachmentto a glass pane (K) of a peripheral rubber insert (G) bonded thereto by molecular-chemical adhesion is carried out during the dimensional conformation stage of the rubber, and formation on the bonded insert (G) of one or more grip profiles (10); and co-moulding incorporation of the adhesion bonded inserttothe glass pane in the frame border of the load bearing structure in such a way that the resin thereof spreads into the grip profiles (10) to copenetrate them in interlocking relationship.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
27 words
A method for intimately connecting and sealing a glass pane to a mouldable polymeric material structure, characterized in that it comprises, in succession, the following processing steps:
Claim 2
Independent Claim
27 words
A method for intimately connecting and sealing a glass pane to a mouldable polymeric material structure, characterized in that it comprises, in succession, the following processing steps:
Claim 3
Dependent Claim
106 words
providing the glass pane with a peripheral rubber insert adhesion bonded thereto by chemical-molecular adhesion during the dimensional conformation stage of the rubber; providing on said adhesion bonded insert, during the dimensional conformation stage thereof, one or more, continuous or non-continuous, section member profiles effective to allow the later applied polymeric material to be gripped thereon; and incorporating by co-moulding and at least in part, the insert adhesion bonded to the glass pane, into the frame of the polymeric material load bearing structure, said structure being moulded in a mould limited at least to the contour of the insert intended for incorporation to the polymeric material.
Claim 4
Dependent Claim
106 words
providing the glass pane with a peripheral rubber insert adhesion bonded thereto by chemical-molecular adhesion during the dimensional conformation stage of the rubber; providing on said adhesion bonded insert, during the dimensional conformation stage thereof, one or more, continuous or non-continuous, section member profiles effective to allow the later applied polymeric material to be gripped thereon; and incorporating by co-moulding and at least in part, the insert adhesion bonded to the glass pane, into the frame of the polymeric material load bearing structure, said structure being moulded in a mould limited at least to the contour of the insert intended for incorporation to the polymeric material.
Claim 5
Dependent Claim
38 words
A method according to Claim 1; wherein said insert has at least one portion adapted for incorporation into the polymeric material of said load bearing structure and provided with at least one grip profile for said polymeric material.
Claim 6
Independent Claim
35 words
A method according to Claims 1 and 2, wherein said insert has at least one portion adapted to remain exposed to the outside against which the closure of the polymeric structure mould makes a seal.
Claim 7
Independent Claim
15 words
A method according to the preceding claims, wherein said load bearing structure is injection moulded.
Claim 8
Independent Claim
20 words
A method according to the preceding claims, wherein said load bearing stIUcture is moulded from an optionally filled thermoplastic resin.
Claim 9
Dependent Claim
49 words
A method according to Claim 1, characterized in that it also comprises a further intermediate step of surface treating said rubber insert with a primer and/or adhesive effective to establish a chemical and physical bond between said insert rubber and structure resin during the moulding step of the latter.
Claim 10
Dependent Claim
20 words
A method according to Claim 6, wherein said primer and/or adhesive are compatible both with the rubber and resin polymers.
Claim 11
Dependent Claim
91 words
A product obtained with the method of Claims 1 to 5, characterized in that it comprises a polymeric material structure (SR) having a port filled by a glass pane (K), wherein the glass pane holding and mounting frame border surrounding said port incorporates a rubber insert (G) adhesion bonded to a corresponding peripheral portion of said glass pane (K), and wherein the rubber of said bonded insert (G) is provided with grip profiles (10) whereinto, during the moulding step, the structure resin spreads to co-penetrate said profiles in mutual interlocking relationship.
Claim 12
Dependent Claim
24 words
A product according to Claim 8, characterized in that it comprises an adhesive layer interposed between said insert rubber and structure resin incorporating it.
Claim 13
Dependent Claim
27 words
A product according to Claims 8 and 9, characterized in that it embodies a motor vehicle door member having a port filled by a fixed glass pane.
