Abstract
A vehicle mirror assembly having a housing or base member, a mirror lens and a connecting gasket member. The mirror lens is provided in the shape of a portion of an end of an ellipsoid. The lens has a varying radius of curvature. The center portion of the tens has a smaller radius of curvature than the outer portions along the major axis of the lens creating an improved field of view of the reflected image.
Claims17
A mirror assembly comprising:
- a housing member;
- a mirror lens member comprising a dome lens having a perimeter forming a base comprising a first base portion having a first base radius of curvature and a second base portion having a second base radius of curvature, said dome lens positioned between said first base portion and said second base portion, and said dome lens having a varying dome lens radius of curvature, said varying dome lens radius of curvature having a minimum value positioned between said first base radius of curvature and said second base radius of curvature, said varying dome lens radius of curvature increasing constantly from said minimum value to said first base radius of curvature and said second base radius of curvature, said varying dome lens radius of curvature being greater at said first base radius of curvature than at said second base radius of curvature, wherein the first base radius of curvature is varying and the second base radius of curvature is varying.
A mirror assembly comprising:
- a housing member;
- a mirror lens member comprising a first base portion having a first base periphery, a second base portion having a second base periphery and a dome lens positioned there between having a varying dome lens radius of curvature, said varying dome lens radius of curvature having a minimum value positioned between said first base periphery and said second base periphery, said varying dome lens radius of curvature increasing constantly from said minimum value to said first base periphery and to said second base periphery, and said second base portion being non-parallel to said first base portion, wherein said first base periphery includes a first base radius of curvature, and said second base periphery includes a second base radius of curvature, and wherein the first base radius of curvature is varying and the second base radius of curvature is varying.
A mirror lens assembly comprising:
- a mirror lens member comprising a first base periphery, a second base periphery and a dome lens, said mirror lens member having a minimum radius of curvature positioned in between said first base periphery and said second base periphery and a varying dome lens radius of curvature increasing from said minimum radius of curvature towards said first base periphery and said second base periphery, said first base periphery being different from said second base periphery, wherein said first base periphery includes a first base radius of curvature, and said second base periphery includes a second base radius of curvature, and wherein the first base radius of curvature is varying and the second base radius of curvature is varying.
A mirror assembly comprising:
- a mirror lens member comprising a dome lens generally configured to conform to a geometric shape formed using an ellipse, said mirror lens member comprising a first base portion and a second base portion comprising an intersection of an axis of said ellipse, said intersection being non-perpendicular to said axis.
A mirror assembly comprising:
- a mirror lens member comprising first base periphery, a second base periphery, and a dome lens having a varying dome lens radius of curvature, said varying dome lens radius of curvature configured to generate a first proportion image view located between said first base periphery and said second base periphery, said varying dome lens radius of curvature configured to generate at least one second proportion image view along said first base periphery and said second base periphery, said varying dome lens radius of curvature being greater at said first base periphery than at said second base periphery;
- wherein said second proportion image view displays larger image proportions than said first proportion image view, wherein said first base periphery includes a first base radius of curvature, and said second base periphery includes a second base radius of curvature, and wherein the first base radius of curvature is varying and the second base radius of curvature is varying.
