A vehicular interior rearview mirror assembly includes a mounting portion, a mirror casing and a mirror reflective element. The reflective element includes a glass substrate having a planar front surface, a planar rear surface and a circumferential perimeter edge around a periphery of the glass substrate that extends across a thickness dimension separating the planar front surface from the planar rear surface. A front perimeter edge portion of the circumferential perimeter edge includes a rounded glass surface circumferentially around the periphery of the glass substrate, with the rounded glass surface at least partially spanning the thickness dimension of the glass substrate. The rounded glass surface has a radius of curvature of at least 2.5 mm. The planar rear surface of the glass substrate is coated with a coating. No portion of the mirror casing overlaps onto the rounded glass surface of the glass substrate.

A vehicular interior rearview mirror assembly includes a reflective element assembly portion that includes a mirror reflective element and at least one pivot element, which provides adjustability of the mirror reflective element when the reflective element assembly portion is mounted within an interior cabin of a vehicle. A cap portion is adapted to attach to the reflective element assembly portion. The cap portion includes at least one accessory. The at least one accessory includes an accessory module insertable at least partially into the cap portion. Insertion of the accessory module into the cap portion connects the accessory module to the cap portion both mechanically and electrically. The cap portion may encase a rear portion of the reflective element assembly portion, and a mounting member may extend from the pivot element and through an aperture of the cap portion for mounting the mirror assembly within the interior cabin of the vehicle.

A display system includes: a display device in a mobile body; a concave mirror for displaying, in a first mode, a virtual image of a display image shown by image light emitted by the display device; and a plane mirror for reflecting, in a second mode, a rear-view image shown by light that has entered the mobile body. In a top view of the mobile body, the display device and the concave mirror are disposed such that a straight line connecting centers of the display device and the concave mirror has a predetermined angle relative to a front-and-rear direction of the mobile body. A normal direction at a center of a concave mirror surface of the concave mirror when the first mode is functioning and a normal direction normal to a plane mirror surface of the plane mirror when the second mode is functioning are not parallel.

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 vehicular interior rearview mirror assembly includes a mirror casing and a 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. The reflective element is accommodated at the principal mirror casing portion. An upper portion of the pivotable mirror casing portion is integrally joined with the principal mirror casing portion at an upper region of the principal mirror casing portion. A spring element is coupled to the pivotable mirror casing portion and to a lower region of the principal mirror casing portion. The spring element flexes to adjust an angle of the principal mirror casing portion and the reflective element relative to the pivotable mirror casing portion of the mirror casing.

A method of assembling a mirror head for an interior rearview mirror assembly for a vehicle includes providing a mirror casing, a prismatic reflective element at the mirror casing, and a toggle mechanism. A pivot mount of the toggle mechanism is inserted into an upper or lower receiving portion of the mirror casing, and a body portion of the toggle mechanism is separated from a toggle lever of the toggle mechanism via breaking a frangible portion of the toggle mechanism. After breaking the frangible portion of the toggle mechanism, a second pivot mount of the toggle mechanism is inserted into the lower or upper receiving portion of the mirror casing, whereby corresponding engaging surfaces of the body portion and the toggle lever engage one another such that, when the toggle lever pivots relative to the lower receiving portion of the mirror casing, the mirror casing pivots relative to the body portion.
