Abstract:
A vehicular rearview mirror assembly includes a mirror head having a mirror casing and an electro-optic mirror reflective element. A mirror casing sidewall has a terminal end region that circumscribes an open end of the mirror casing and has a rounded end region surface. A first substrate of the reflective element has a rounded circumferential perimeter region extending at least partially between a front surface and a rear surface of the first substrate and having a first radius of curvature. The rounded surface of the mirror casing has a second radius of curvature. The substrate thickness of the first substrate is less than the first radius of curvature. The rounded surface of the mirror casing and the rounded circumferential perimeter region of the first substrate combine to provide a curved transition between the front surface and the outer surface of the mirror casing.
Abstract:
An electro-optic rearview mirror assembly for a vehicle includes a caseless electro-optic rearview mirror reflective element and a plate attached at the rear of the reflective element. The mirror reflective element connected to and pivotal about a windshield electronics module via a ball and socket pivot joint. Control circuitry may be disposed in a windshield electronics module for automatically controlling dimming of the electro-optic medium or alternatively, dimming of the electro-optic medium is automatically controlled via a multifunctional rear backup camera system of the equipped vehicle. Optionally, the control circuitry controls dimming of the electro-optic medium of the mirror reflective element via wiring that passes through the ball and socket pivot joint. Optionally, image data captured by the multifunctional rear backup camera may be used for ambient light determination and to provide video image display at the interior rearview mirror assembly.

Abstract:
A blind zone indicator module for a vehicular exterior rearview mirror assembly includes a hollow housing that includes a front end for attaching the indicator module at the rear of a mirror reflective element configured for use by an exterior rearview mirror assembly, a rear end opposite the front end, and an intermediate portion between the front end and the rear end. The hollow housing comprises an inner surface that is white and is diffusely reflective of light incident thereat. A diffuser element is attached at the front end of the hollow housing and closes the front end of the housing. Potting material is disposed at and over a circuit board to seal the circuit board in the module. Light emitted by a light emitting diode, when activated, reflects off the white inner surface of the hollow housing and passes through the diffuser element to exit the indicator module.
Abstract:
A method for manufacturing an indicator module for an exterior rearview mirror assembly for a vehicle includes providing a hollow housing formed by injection molding of plastic material and providing a circuit board having a first side and a second side opposite the first side, with at least one light emitting diode disposed at the first side of the circuit board. The circuit board is disposed between a rear end and a front end of the housing such that the first side of the circuit board faces the front end of the housing. With the circuit board disposed between the rear and front ends of the housing, potting material is disposed at and over the second side of the circuit board to seal the rear side of the circuit board. A diffuser element is attached at the front end of the housing and closes the front end of the housing.
Abstract:
An interior rearview mirror assembly for a vehicle includes a mirror casing and a mirror reflective element disposed at an outer end region of a sidewall of the mirror casing. The mirror reflective element includes a first glass substrate having a front surface and a rear surface and a substrate thickness spanning between the front and rear surfaces. The first glass substrate includes a flat region and a rounded perimeter edge circumscribing the flat region. Curvature of a rounded outside surface of the outer end region of the sidewall matches curvature of the rounded perimeter edge of the first glass substrate whereby the rounded outside surface of the outer end region of the sidewall and the rounded perimeter edge of the first glass substrate combine to provide a curved transition between the front surface of the flat region and a principal outside surface of the sidewall of the mirror casing.
Abstract:
An interior rearview mirror assembly for a vehicle includes a mirror head having a mirror reflective element with a transflective mirror reflector. A video display device is disposed rearward of the mirror reflective element, and a polymer reflector layer is disposed in front of the video display device. The video display device is operable to display video images captured by a rearward viewing camera of the vehicle. When the video display device is operated to display video images, light emitted by the video display device passes through the polymer reflector layer and the mirror reflective element for viewing of displayed video images by a driver of the vehicle viewing the mirror reflective element. Linearly polarized light emitted by the video display device is circularly polarized as it passes through the polymer reflector layer, such that the displayed video images comprise circularly polarized light.
Abstract:
An interior rearview mirror assembly for a vehicle includes a mirror head having a mirror reflective element, and a video display device behind the mirror reflective element and viewable through the mirror reflective element when activated. The video display device includes a display screen that occupies at least 75 percent of a reflective region of the mirror reflective element. The video display device includes a backlighting array of light emitting diodes for backlighting the display screen, and the backlighting array of light emitting diodes includes a plurality of zones of light emitting diodes, with each zone having at least two light emitting diodes. The zones of light emitting diodes are independently controlled based on the video images being displayed by the video display device.
Abstract:
An exterior rearview mirror assembly for a vehicle includes a mirror head and an exterior mirror reflective element fixedly attached at the mirror head. An attachment portion is configured for attachment at an exterior portion of the vehicle. The mirror assembly includes a multi-axis adjustment mechanism having at least one electrically-operable actuator. The multi-axis adjustment mechanism is operable to move the mirror head, with the exterior mirror reflective element fixedly attached thereto, about multiple axes relative to the attachment portion. The exterior mirror reflective element moves in tandem with movement of the mirror head relative to the exterior portion of the body of the vehicle to adjust the rearward field of view of a driver of the vehicle who views the exterior mirror reflective element when operating the vehicle.
Abstract:
A rearview mirror assembly for a vehicle includes a mirror casing and a mirror reflective element disposed at the mirror casing. The mirror reflective element includes at least a first glass substrate having a front surface and a rear surface. When the rearview mirror assembly is normally mounted in a vehicle, the front surface is closer than the rear surface to a driver that is normally operating the vehicle. The first glass substrate has a flat central region and a rounded perimeter edge, and the rounded perimeter is exposed to and is viewable by the driver of the vehicle. With the mirror reflective element disposed at the mirror casing, no portion of the mirror casing encompasses the rounded perimeter edge. The rounded perimeter edge has a glare-reducing surface finish.
