Claims21
A laminated vehicle glazing with two glass layers, said vehicle glazing, comprising:
- at least one stiffening portion, which modifies the geometry of the two glass layers, each at least one stiffening portion corresponding to a bent section of a surface having at least a portion of its contour being curved;
- a plastic interlayer disposed between the two glass layers;
- wherein the bent section, in a planar view thereof, has a geometric shape selected from the group consisting of a circle, an oval, an ellipse, a polygon and a polygon with rounded corners;
- wherein each portion of the at least one stiffening portion is selected from the group consisting of a recessed portion and a raised portion;
- wherein the curved portion comprises a first bent portion described by a first radius and a second bent portion described by a second radius;
- wherein the first radius and the second radius are no more than 50 mm;
- wherein each stiffening portion extends across a dimension of the glass;
- and
- wherein each at least one stiffening portion has a distance between its two furthest points larger than one third of the length of the shortest side of the rectangle's side that subscribes the vehicle glazing.
