Problems are encountered when producing a laminated version of a tempered part with holes, because tempered glass is 4 to 5 times stronger than annealed glass. The laminate of the invention has a hole in the exterior glass layer. An insert is bonded to a cutout in the area of the hole on the interior glass layer so as to reinforce the hole and distribute the load over a wider area. The result is a laminated glazing with one or more holes that has the reliability of and is a direct replacement for a tempered part. ## Claims ### Claim 1 A laminated automotive glazing comprising: an exterior glass layer having inner and outer surfaces, said exterior glass layer comprising at least one hole; an interior glass layer having inner and outer surfaces, said interior glass layer comprising at least one cutout in an area corresponding to said at least one hole in the exterior glass layer such that said at least one cutout exposes the inner surface of the exterior glass layer in an area in and surrounding said at least one hole; at least one plastic bonding layer positioned between exterior and interior glass layers and serving to bond the inner surfaces of said glass layers; and an insert is disposed in the area corresponding to the cutout of the interior glass layer and is bonded to the inner surface of the exterior glass layer; wherein the insert has at least one hole in alignment with said at least one hole in the exterior glass layer. ### Claim 2 (depends on 1) The laminated glazing of claim 1, wherein said at least one hole in the insert is of a smaller diameter than said at least one hole in the exterior glass layer. ### Claim 3 (depends on 1) The laminated glazing of claim 1, wherein the insert is of a thickness that is about the same as the interior glass layer. ### Claim 4 (depends on 1) The laminated glazing of claim 1, wherein the insert is of a thickness that is greater than that of said interior glass layer. ### Claim 5 (depends on 1) The laminated glazing of claim 1, which further comprises a reinforcement, wherein the insert is positioned between the exterior glass layer and said reinforcement. ### Claim 6 (depends on 1) The laminated glazing of claim 1, which further comprises sleeve inserted through the hole and with retainers at each side of the laminated glazing, the sleeve and retainers being made of at least one of the following materials: carbon fiber composite, steel, aluminum, titanium, plastic, and fiberglass reinforced plastic. ### Claim 7 (depends on 1) The laminated glazing of claim 1, wherein the insert is substantially made of at least one of the following materials: glass, carbon fiber composite, steel, aluminum, titanium, plastic, and fiberglass reinforced plastic. ### Claim 8 (depends on 1) The laminated glazing of claim 1, wherein said insert at least partially overlaps the interior glass layer. ### Claim 9 (depends on 1) The laminated glazing of claim 1, wherein said insert at least partially overlaps the interior glass layer and said overlap is bonded to the interior glass layer. ### Claim 10 (depends on 1) The laminated glazing of claim 1, further comprising a mechanism wherein said mechanism places the exterior glass layer in compression. ### Claim 11 (depends on 1) The laminated glazing of claim 1, wherein at least one of said glass layers is chemically tempered. ### Claim 12 (depends on 1) The laminated glazing of claim 1, wherein at least one of said glass layers is heat strengthened. ### Claim 13 (depends on 1) The laminated glazing of claim 1, wherein at least one of said glass layers is less than about 1.2 mm thick. ### Claim 14 (depends on 1) The laminated glazing of claim 1, wherein at least one of said glass layers is less than about 0.7 mm thick. ### Claim 15 (depends on 1) The laminated glazing of claim 1, further comprises a performance plastic layer selected from the group of a heat absorbing layer or an infrared reflecting layer. ### Claim 16 (depends on 1) The laminated glazing of claim 1, wherein the insert is bonded to the inner surface of the exterior glass layer by said at least one plastic bonding layer using a standard automotive autoclave cycle. ### Claim 17 (depends on 1) The laminated glazing of claim 1, wherein at least one of said glass layers is comprised of an aluminosilicate glass. ### Claim 18 (depends on 1) The laminated glazing of claim 1, wherein at least one of said glass layers is comprised of a borosilicate glass. ### Claim 19 (depends on 1) The laminated glazing of claim 1 is an automotive rear window or side window. ### Claim 20 (depends on 1) The laminated glazing of claim 1, wherein a wiper or lift rail mechanism is mounted to said laminate going through said holes. ### Claim 21 (depends on 1) The laminated glazing of claim 1, wherein said insert is formed to the exterior glass layer contour. ### Claim 22 (depends on 1) The laminated glazing of claim 1, wherein the insert is bonded to the inner surface of the exterior glass layer by adhesive means. ### Claim 23 (depends on 6) The laminated glazing of claim 6, wherein the insert is held in place by friction and pressure. ### Claim 24 A laminated automotive side window comprising: an exterior glass layer having inner and outer surfaces, said exterior glass layer comprising at least one hole; an interior glass layer having inner and outer surfaces, said interior glass layer comprising at least one cutout in an area corresponding to said at least one hole in the exterior glass layer such that said at least one cutout exposes the inner surface of the exterior glass layer in the areas in and surrounding said at least one hole; at least one plastic bonding layer positioned between the exterior and interior glass layers and serving to bond inner surfaces of said glass layers; and at least one insert bonded to the inner surface of the exterior glass layer; wherein each insert of said at least one insert is disposed in a respective cutout area of the interior glass layer, and has at least one hole, each hole being in alignment with a corresponding hole of the exterior glass layer. ### Claim 25 (depends on 24) The laminated automotive side window of claim 24 wherein the exterior glass layer comprises two holes.
