Abstract
Official abstract text for this publication.
A automobile laminated glass according to the present invention includes: a curved outer glass plate; a curved inner panel that is smaller than the outer glass plate and is disposed opposing the outer glass plate; and an intermediate film that includes a functional layer and is disposed between the outer glass plate and the inner panel, wherein at least a portion of the inner panel is located inward of a peripheral edge of the outer glass plate.
First claim
Opening claim text (preview).
1 . An automobile laminated glass comprising: a curved outer glass plate; a curved inner glass that is smaller than the outer glass plate and is disposed opposing the outer glass plate; and an intermediate film that includes a functional layer and is disposed between the outer glass plate and the inner glass, wherein at least a portion of the inner glass is located inward of a peripheral edge of the outer glass plate. 2 . The automobile laminated glass according to claim 1 , wherein when a horizontal curvature radius of an opposing region of the outer glass plate where the outer glass plate opposes the inner glass plate is defined as Rx (mm), and a vertical curvature radius of the outer glass plate is defined as Ry (mm), and 1/Rx*1/Ry*10 −6 is defined as a curvature index, the curvature index is 2.4 or less. 3 . The automobile laminated glass according to claim 2 , wherein the curvature index in the opposing region is 1.3 or less. 4 . The automobile laminated glass according to claim 2 , wherein Rx is 200 to 200,000 mm, and Ry is 1,700 to 5,000 mm. 5 . The automobile laminated glass according to claim 1 , including at least one protruding portion curved to an outer side of a vehicle when the automobile laminated glass is attached to the vehicle. 6 . The automobile laminated glass according to claim 1 , wherein the functional layer is a dimming film. 7 . The automobile laminated glass according to claim 6 , wherein the dimming film is a PDLC-type or SPD-type film. 8 . The automobile laminated glass according to claim 6 , wherein a terminal for applying a voltage to the dimming film is disposed in a lower end portion of the inner glass plate. 9 . The automobile laminated glass according to claim 1 , wherein the intermediate film is formed by a plurality of sheet members, and the plurality of sheet members are arranged spaced apart from each other. 10 . The automobile laminated glass according to claim 1 , wherein the inner glass is formed by a glass plate. 11 . The automobile laminated glass according to claim 1 , wherein the outer glass plate includes a window region that allows passage of light from outside a vehicle, and a blocking region in which a blocking layer is laminated surrounding the window region so as to block the passage of light from outside the vehicle, and the inner glass is attached so as to cover the window region. 12 . The automated laminated glass according to claim 1 , wherein the automated laminated glass is a rear glass panel, a rear quarter glass panel, or a side glass panel. 13 . The automated laminated glass according to claim 1 , wherein the outer glass plate has a thickness of 1.6 mm to 4 mm, and the inner glass has a thickness of 0.3 to 2.3 mm. 14 . The automobile laminated glass according to claim 1 , wherein the intermediate film includes a pair of the adhesion layers, and the functional layer is disposed between the pair of adhesion layers.
