A vehicular interior rearview mirror assembly includes a mounting structure configured for mounting at an interior portion of a vehicle. The mounting structure includes a mounting arm that has (i) a proximal end portion and (ii) a distal end portion distal from the proximal end portion. With the mounting structure mounted at the interior portion of the vehicle, the proximal end portion of the mounting arm is attached at the interior portion of the vehicle. A motorized actuator is disposed within a mirror housing that accommodates a reflective element. The motorized actuator is electrically operable to adjust the reflective element and the mirror housing together and in tandem relative to the mounting structure to provide a desired rearward field of view to a driver of the vehicle when the vehicular interior rearview mirror assembly is mounted and operated in the vehicle.

A vehicular frameless interior rearview mirror assembly includes a mirror head and a mounting portion. The mirror head includes a mirror reflective element and a mirror casing. The mirror reflective element includes a glass substrate having a planar front side and a planar rear side. No portion of the mirror casing overlaps the planar front side of the glass substrate of the mirror reflective element. A camera is disposed within the mirror casing. With the mounting portion of the mirror assembly mounted at an in-cabin side of a windshield of a vehicle, the camera views a driver of the vehicle, and when the mirror head is moved by the driver of the vehicle to adjust the rearward view provided by the mirror reflective element to the driver, the camera moves in tandem with movement of the mirror head. The camera is part of a driver monitoring system of the vehicle.

A method of making a mirror substrate for a vehicular mirror assembly includes providing a glass substrate and fixturing the glass substrate at a fixture to support the glass substrate. A rotatable grinding wheel is presented to the front perimeter portion of the glass substrate and the front perimeter portion of the glass substrate is ground to establish a ground rounded surface about and around the periphery of the glass substrate. After grinding the front perimeter portion of the glass substrate to establish the ground rounded surface, a rotatable polishing wheel is presented to the ground rounded surface and the ground rounded surface is polished to establish a polished rounded surface about and around the periphery of the glass substrate. The polished rounded surface provides a smooth transition between the front surface of the glass substrate and a rear portion of the circumferential perimeter edge of the glass substrate.

An interior rearview mirror assembly includes an interior prismatic mirror reflective element having a wedge-shaped glass substrate having a circumferential edge along the periphery of said glass substrate. The circumferential edge spans a thickness of the glass substrate between its front and rear surfaces. The prismatic mirror reflective element has a mirror reflector established at the rear surface of the glass substrate. A plastic molding is circumferentially disposed about the circumferential edge of the glass substrate without overlapping onto the front surface of the glass substrate. The outermost part of the plastic molding curves and the plane of the front surface of the glass substrate is generally flush with the outermost part of the plastic molding.

An interior rearview mirror assembly for a vehicle includes a mirror casing and a prismatic reflective element, with the mirror casing adjustably supported at a mirror mount at an interior surface of the vehicle. The mirror casing includes a principal mirror casing portion and a pivotable mirror casing portion that is pivotable relative to the principal mirror casing portion. A toggle assembly includes a toggle lever and a spring element disposed between and coupled to the toggle lever and the pivotable mirror casing portion of the mirror casing. Pivotal movement of the toggle lever flexes the spring element and adjusts the angle of the principal mirror casing portion and the prismatic reflective element relative to the pivotable mirror casing portion of the mirror casing.

A vehicular frameless interior rearview mirror assembly includes a mirror head and a mounting portion. The mirror head includes an electrochromic mirror reflective element and a mirror casing. The electrochromic mirror reflective element includes a front glass substrate having a planar front side. No portion of the mirror casing overlaps the planar front side of the front glass substrate of the electrochromic mirror reflective element. A camera is disposed within the mirror casing. With the mounting portion of the mirror assembly mounted at an in-cabin side of a windshield of a vehicle, the camera views a driver of the vehicle, and when the mirror head is moved by the driver of the vehicle to adjust the rearward view provided by the mirror reflective element to the driver, the camera moves in tandem with movement of the mirror head. The camera is part of a driver monitoring system of the vehicle.

An actuation mechanism for a vehicle mirror includes a mounting unit and a support plate coupleable with a rearview. A latch pin is slidably engaged with the support plate and with the mounting unit and moveable into a first retention position with respect to the support plate and the mounting unit that maintains the support plate in a first rotational position with respect to the mounting unit against the force of a first spring. The latch pin is further moveable into a second retention position with respect to the support plate and the mounting unit that maintains the support plate in a second rotational position with respect to the mounting unit against the force of the first spring. A release button is moveably coupled with the latch pin and moving the latch pin out of the second retention position on movement of the release button toward the mounting unit.

A vehicular interior rearview mirror assembly includes a mounting structure and a mirror head adjustable about the mounting structure. The mirror head accommodates a mirror reflective element comprising a glass substrate. With the vehicular interior rearview mirror assembly mounted at an interior portion of a vehicle, the mirror head is adjustable about the mounting structure by a driver of the vehicle to adjust the driver's rearward view. The glass substrate includes a periphery surface extending between a planar first surface and a planar second surface and spanning the thickness dimension of the glass substrate. The planar first surface faces the driver of the vehicle. No part of the mirror casing encroaches onto the planar first surface of the glass substrate. The mirror head accommodates a video device for internal cabin surveillance, and wherein the internal cabin surveillance includes detection of drowsiness of the driver of the vehicle.
