Vehicle Rearview Mirror With Spotter Mirror

US Patent:
8264761, Sep 11, 2012
Filed:
Jan 4, 2011
Appl. No.:
12/984187
Inventors:
David J. Cammenga - Zeeland MI, US
Brian J. Steenwyk - Holland MI, US
Michael L. McLarty - Holland MI, US
Randall S. Braun - Hudsonville MI, US
Assignee:
Gentex Corporation - Zeeland MI
International Classification:
G02F 1/155
G02F 1/15
G02B 5/08
US Classification:
359266, 359265, 359866
Abstract:
A mirror element comprising a front element, a rear element, electrochromic material therebetween, and a spotter optic located at the rear surface of the front element. At least a portion of the spotter optic has a first radius of curvature and at least a portion of the front surface of the front element has a greater second radius of curvature. A line perpendicular to the front surface extends through both the electrochromic material and the spotter optic. A first electrode coating and a second electrode coating are activated to activate the electrochromic material in order to dim a reflection off of the mirror element. A reflective coating of the spotter optic can form a portion of the first electrode coating. The first electrode coating and the reflective coating can overlap.

US Patent:
8643931, Feb 4, 2014
Filed:
Jun 29, 2011
Appl. No.:
13/171950
Inventors:
David J. Cammenga - Zeeland MI, US
Brian J. Steenwyk - Holland MI, US
Michael L. McLarty - Holland MI, US
Randall S. Braun - Hudsonville MI, US
Assignee:
Gentex Corporation - Zeeland MI
International Classification:
G02F 1/155
G02F 1/15
G02B 5/10
G09G 3/19
H04N 9/16
US Classification:
359266, 359265, 359868, 345 49, 348817
Abstract:
An exterior rearview mirror element including a front element having a first front surface and a second rear surface. A cross-section of the second rear surface defines a first line. A rear element includes a third front surface and a fourth rear surface. Electrochromic material is located between the front element and the rear element. A spotter optic is located in the second rear surface of the front element. A cross-section of the spotter optic defines a second line. A transition region is disposed between the spotter optic and the second rear surface of the front element. A distance from a surface of the transition region to an intersection of the first line and the second line is between about 0. 001 mm and 0. 034 mm. At least a portion of the spotter optic includes a first radius of curvature and at least a portion of the first front surface includes a second radius of curvature, the first radius of curvature being smaller than the second radius of curvature.
