Abstract
(EN)
This glass plate (1) comprises a first surface (10) and a second surface (20) opposite of the first surface (10), the second surface (20) is chemically strengthened, and the compressive stress generated by ion exchange in the second surface (20) is greater than the compressive stress generated by ion exchange in the first surface (10). The glass plate (1) curves about a first axis (X) with the first surface (10) a concave surface and the second surface (20) a convex surface. In cross-sectional view of a plane (A) perpendicular to the first axis (X), when the intersection of the first axis (X) and the plane (A) is set as the origin, the cross-section of the second surface (20) is a circular arc centered on the origin (O).
(FR)
La plaque de verre (1) de l'invention possède une première face (10), et une seconde face (20) s'opposant à la première face (10). La seconde face (20) est soumise à une trempe chimique. La contrainte de compression produite par échange d'ions de la seconde face (20), est supérieure à celle produite par échange d'ions de la première face (10). Lorsque la première face (10) consiste en une face concave, et la seconde face (20) consiste en une face convexe, et lorsque le point d'intersection entre un premier axe (X) et un plan (A) consiste en une origine (O), selon une vue en plan transversale au niveau d'un plan (A) courbe autour d'un premier axe (X) et perpendiculaire à ce premier axe (X), alors le plan transversal de la seconde face (20) consiste en un arc de cercle ayant l'origine (O) pour centre.
