<p>An electro-optically dimming exterior rearview mirror (111) for automotive vehicles, said mirror comprising, in combination, front and rear spaced elements (114,118), said front element (114) being optically transparent and including an inboard portion (140) and an outboard portion (114A) projecting laterally outwardly of said inboard portion, at least one of said inboard and outboard portions (114A,B) of said front element being of curved configuration, said front element and said rear element defining a chamber therebetween, the confronting sides of said front element and said rear element each including at least one layer of electrically conductive material (22,26) said chamber containing an electro-optic reversibly variable transmittance medium (124) in contact with each of said electrically conductive layers, said rear element including light reflecting means (20,22), said light reflecting means of said rear element being effective to reflect light through said medium and through said front element when said light reaches said rear element reflecting means after passing through said medium and through said front element, and means for applying electrical potential to said layers of electrically conductive material to cause variation in the light transmittance of said electro-optic medium.</p> |
