The laminated glazing proposed in this invention has an outer glass layer (201) with holes (20) and a thin inner facing glass layer (202) with shorter length dimension whereas the bottom edge (30) does not have holes on it and which does not overlap with the holes (20) in the outer glass layer (201). One or more retention layers (36), comprising reinforcement and adhesive layers, serve to connect the glazing mounting means (32) to both of the glass layers (201, 202) providing a thin laminated glazing with holes (20) that in the event of failure is retained by the mounting means (32).
An automotive glazing having a vision area when installed as a window in a vehicle, the automotive glazing comprising:
The laminated glazing according to any one of the preceding claims, wherein the inner glass layer thickness is between 0.5 mm and 1.6 mm.
The laminated glazing according to claim 4, wherein the inner glass layer thickness is between 0.5 mm and 1.1 mm.
The laminated glazing according to any one of the preceding claims, wherein the reinforcement layer has a tensile strength at break between 30 and 1000 MPa, preferably between 150 and 1000 MPa.
The laminated glazing according to any one of the preceding claims, wherein the reinforcement layer is comprised of at least one of the following materials:
The laminated glazing according to any one of the preceding claims, wherein the adhesive layer has a peel adhesion to glass about equal to that of the plastic bonding layer.
The laminated glazing according to any one of the preceding claims, wherein the adhesive layer is substantially comprised of at least one of the following materials:
The laminated glazing according to any one of the preceding claims, wherein the reinforcement layer overlaps with all of the surface of the non-laminated section.
The laminated glazing according to any one of the preceding claims, wherein the reinforcement layer has holes concentric to the outer glass layer holes.
The laminated glazing according to any one of the preceding claims, wherein the reinforcement layer extends at least 10 mm above the lower edge of the inner glass layer.
The laminated glazing according to any one of the preceding claims, wherein the lower edge of the inner glass layer is extended by at least 20 mm below the beltline of the laminated glazing.
The laminated glazing according to any one of the preceding claims, wherein the outer glass layer is thermally strengthened to a compressive stress of between 60 and 150 MPa, preferably between 100 and 140 MPa.
The laminated glazing according to any one of the preceding claims, wherein the inner glass layer is chemically strengthened to a compressive stress of between 400 and 900 MPa, preferably between 500 to 800 M pa.
The laminated glazing according to any one of the preceding claims, wherein the edge of the inner glass layer is offset inboard from the edge of the outer glass layer along a substantial portion of the glass edge.
The laminated glazing according to any one of the preceding claims, wherein the inner glass layer has a chamfered or bullnose edge finish along at least the exposed portion of the edge.
