Frameless interior rearview mirror assembly

A vehicular frameless interior rearview mirror assembly, the vehicular frameless interior rearview mirror assembly comprising:

• a mirror head and a mounting portion;
• wherein the mounting portion comprises a mounting base configured to attach the vehicular frameless interior rearview mirror assembly to an attachment element that is adhered at an in-cabin side of a windshield of a vehicle equipped with the vehicular frameless interior rearview mirror assembly;
• wherein the mirror head is pivotable relative to the mounting portion via at least one ball-and-socket pivot joint;
• wherein the mirror head comprises a mirror reflective element and a mirror casing;
• wherein the mirror reflective element of the vehicular frameless interior rearview mirror assembly comprises a prismatic mirror reflective element;
• wherein, when the mirror head is moved relative to the mounting portion, the mirror reflective element and the mirror casing move in tandem with movement of the mirror casing;
• wherein the mirror reflective element comprises a glass substrate having a planar front side and a planar rear side;
• wherein the plane of the planar front side of the glass substrate is at an acute angle relative to the plane of the planar rear side of the glass substrate, and wherein the planar rear side of the glass substrate comprises a mirror reflector;
• a circumferential perimeter glass edge circumscribing a periphery of the glass substrate, the circumferential perimeter glass edge spanning a thickness dimension of the glass substrate separating the planar front side from the planar rear side;
• wherein no portion of the mirror casing overlaps the planar front side of the glass substrate;
• wherein a portion of the mirror casing circumscribes the circumferential perimeter glass edge circumscribing the periphery of the glass substrate;
• wherein the portion of the mirror casing that circumscribes the circumferential perimeter glass edge circumscribing the periphery of the glass substrate comprises a plastic molding;
• wherein the plastic molding that circumscribes the periphery of the glass substrate without overlapping the planar front side of the glass substrate comprises an outermost part;
• wherein the outermost part of the plastic molding has a radius of curvature of at least 2.5 mm;
• wherein the outermost part of the plastic molding, with the mounting portion of the vehicular frameless interior rearview mirror assembly mounted at the in-cabin side of the windshield of the equipped vehicle, is contactable by a driver of the equipped vehicle;
• wherein, with the plastic molding of the mirror casing circumscribing the circumferential perimeter glass edge of the glass substrate, the outermost part of the plastic molding provides a curved transition between the planar front side of the mirror reflective element and another part of the mirror casing;
• wherein a camera is disposed within the mirror casing behind the mirror reflective element;
• wherein, with the mounting portion of the vehicular frameless interior rearview mirror assembly mounted at the in-cabin side of the windshield of the equipped vehicle, the camera views the driver of the equipped vehicle through the mirror reflective element;
• wherein, with the mounting portion of the vehicular frameless interior rearview mirror assembly mounted at the in-cabin side of the windshield of the equipped vehicle and when the mirror head is moved by the driver of the equipped 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;
• and
• wherein the camera is part of a driver monitoring system of the equipped vehicle.
