SUBSTRATE FOR MIRROR SUPPORT WITH REDUCED WEIGHT AND MIRROR PROVIDED WITH MIRROR SUPPORT WITH REDUCED WEIGHT
- To provide a substrate for a mirror support, in which there still remains a high rigidity, despite a reduced weight. ;SOLUTION: In a substrate, particularly in a substrate for a mirror support, in which recesses are introduced in one surface, preferably in the back side of the substrate, as a result of which, in particular, bridging pieces are defined between the recesses, in order to achieve the situation in which despite a reduced weight, a high rigidity still remains, which means only a slight sagging after the correct take-in of the substrate in a holding device provided for it, at least one first position of the bridging pieces includes a width that is different from a second portion of the bridging pieces.
