`
`FIELD OF THE JNVENTJON
`
`The presem invention relates generally to the field of
`rearview mirror assemblies for vehicles and, more particu(cid:173)
`larly, to an interior rearview mirror assembly that has user
`inputs. such as for a telematics system or the like.
`
`BACKGROUND OF THE INVENTION
`
`Typically, an i111erior rearview mirror assembly may
`include user inputs, such as bultons or the like, at a mirror
`bezel portion of the mirror casing, whereby actuation of the
`user inputs activates or adjusts or controls a telematics
`feature. such as a hands free telephone feat11re o r the like.
`
`SUMMARY OF THE JNVENTION
`
`2
`an icon established in front of the sensor for viewing through
`the reflective element by a person viewing the mirror
`assembly when the mirror assembly is normally mounted in
`a vehicle.
`According to an aspect of the present invention. an
`interior rearview 1uirror assembly for a vehicle includes a
`mirror reflective element comprising at least one glass
`substrate and a mirror reflector established at a surface of the
`glass substrate. A touch sensor is disposed behind the mirror
`10 reflective element and is operable to sense the presence of a
`person's finger at a touch zone at the front surface of the
`mirror reflective element and proximate to the touch sensor.
`An iconistic element or applique is disposed in front of the
`touch sensor and between the touch sensor and the glass
`15 substrate of the mirror reflective element. A backlighting
`device is operable to backlight the touch sensor and the
`applique, and, when backlit, the touch sensor transmits light
`through a touch sensing element of the touch sensor to
`back.light the applique so that an icon established at the
`20 applique is backlit and is viewable through tbe mirror
`reflective element by a driver of the vehicle when the interior
`rearview mirror assembly is normally mounted in the
`vehicle. The touch sensor is substantially light transmissive
`at least at the touch sensing element.
`Optionally, the touch sensing element may comprise a
`substantially non-light-transmissive electrically conductive
`trace established at a generally transparent or translucent
`substrate, with the electrically conductive trace established
`at the substrate in a maimer that allows light emanating from
`30 the back.lighting device to pass through the substrate and the
`touch sensing element. For example. the touch sensing
`element may comprise a panerned electrically conductive
`trace comprising multiple spaced apart traces and wherein
`light emanating from the backJighting device passes through
`35 gaps between the spaced apart traces to backlight the icons
`established at the applique.
`According to anod1er aspect of the present invention. an
`exterior rcarvicw mirror assembly configured for motu11ing
`a t an exterior portion of a vehicle includes a base configured
`for attachment at au exterior portion of a vehicle and a
`1uirror bead altached at tbe base and pivotable relative to the
`base. TI1e mirror bead includes a mirror reflective element.
`A first acn1ator is operable to pivot the base relative to the
`exterior portion of the vehicle about a first pivot axis, and a
`45 second acn1ator operable to pivot the mirror head relative to
`the base about a second pivot axis. The first and second
`actuators are cooperatively operable to pivot the base about
`the first pivot axis and to pivot the mirror head about the
`second pivot axis to adjust the mirror reflective element
`50 relative to the exterior portion of the vehicle to adjust the
`rearward field of view of a driver of the vehicle. The first and
`second actuators may be operable at different rotational
`speeds to adjust the rearward field of view of the driver of
`the vehicle. The first and second pivot axes may be angled
`55 relative to one another at an angle of between about IS
`degrees and about 90 degrees.
`These and other objects, advantages, purposes and fea(cid:173)
`tures of the present invention will become apparent upon
`review of the following specification in conjunction with the
`60 drawings.
`
`The present invention provides an interior rearview mirror
`assembly that includes user inputs or touch or proximity
`sensors disposed behind the reflective element of the mirror
`assembly and operable to sense the presence of a user's
`finger at or near the front surface of the reflective element
`and in the vicinity of the touch or proximity sensor. The
`touch sensor comprises a backlit sensor element that com(cid:173)
`prises a plurality of electrically conductive traces disposed
`or established at a transparent or translucent substrate. with
`the electrically conductive traces being established as a 65
`pattern that allows for light emanating from the backlighting
`device or element to pass through the sensor for backlighting

`
`DESCRIPTION OF THE PREFERRED
`EMBODIMENTS
`
`Referring now to the drawings and the illustrative
`embodiments depicted therein, an inte rior rearvicw mirror
`assembly 10 for a vehicle includes a reflective element 14
`positioned at a front portion of a mirror housing or casing 12
`(FIGS. 1-6). Mirror assembly 10 is adjustably mounted to an
`interior portion of a verucle (such. as to an interior surface of
`a vehicle windshleld or a headJ iner of a verucle or the like)
`via a mounting stn1c111re or mounting configuration or
`assembly 18. The mirror assembly 10 includes touch or
`40 proximity sensitive user inputs 20 and associated icons or
`the like so a user can readily identify the purpose or function
`of the user inputs and actuate the appropriate or desired or
`selected user input. In the illustrated embodiment, the user
`inputs 20 are disposed at a lower region of the mirror
`45 reflective element 14. with indicators or icons 22 at an area
`above the respective inputs (and at the principal reflecting
`portion of the reflective element), so that, when a user
`touches or actuates one of the user inputs 20, the respective
`icon 22 is backlit so as to be illuminated for viewing by the
`50 user through tb.e reflective element to confirm to the user that
`the input was actuated (optionally, the mirror assembly may
`provide a haptic feedback, such as a vibration or the like. to
`indicate to the user that a user inplll was touched or
`activated). The reflective element assembly and user inputs
`55 and icons may utilize aspects of the mirror assemblies
`shown and/or described in U.S. Des. Pat. Nos. D633.423;

`user inputs 20 comprise a circuit pad 24 witb substantially
`non-lighHransmissive electrically conductive traces 26
`established a t the circuit pad for sensing a touch o r proximity
`at the sensor or input. As shown in FIGS. 8-11, the electri(cid:173)
`caJly conductive traces 26 are established at each touch input
`area o r region 21a, 2 Jb, 2.1.c in a n1aru1cr that a llows light to
`pass througb the touch pad and touch sensor areas to
`backligbt icons at an applique 28 disposed over or at or in
`front of the circuit pad 24. as discussed below.
`In the illustrated embodiment, the user input circuit pad
`24 is disposed at a lower region of the reflective element and
`is positioned or located at an area tbat is devoid of any
`metallic mirror reflector coatings or the like at the mirror
`substrate or substrates. In the illustrated embodiment, the
`reflective element 14 comprises an electro-optic reflective 15
`element, such as an electrochromic reflective element. and
`includes a front substrate 30 having a front o r first surface
`30a (the surface that generally faces the driver of a vehicle
`when the mirror assembly is normally motmted in the
`vehicle) and a rear or second s urface 30b opposite the front 20
`surface 30a. and a rear substrate 31 having a front or third
`surface 31a and a rear or fourth surface 31b opposite the
`front surface 31a, with an electro-optic medium disposed
`between the second surface 30b and the third surface 31a
`and bounded by a perimeter seal 32 of the reflective element 25
`(such as is known in tl1e electrochromic mirror art). The
`second surface 30a of front substrate 30 has a transparent
`electrically conductive coating established thereat, while the
`third surface 31a of rear substrate 31 has a metallic reflector
`coating established thereat. The mirror reflector may com(cid:173)
`prise any suitable coatings or layers. such as a transflective
`coating or layer. such as described in U.S . Pat. Nos. 7,626,
`749; 7,274.501 ; 7.255,451; 7, 195,381 ; 7,184, 190; 6,690,

`663: 5,910.854; 5,142.407 and/or 4,712.879. which are
`hereby incorporated herein by reference in tl1cir enrireties,
`disposed at the front surface oft11e rear substrate (commonly
`referred to as the third surface of the reflective element) and
`opposing the electro-optic medium, such as an electrochro(cid:173)
`mic mediwn disposed between the front and rear substrates
`and bounded by the perimeter seal (but optionally, the mirror
`reflector could be disposed at the rear surface of the rear
`substrate (commonly referred to as the fourth surface of tl1c
`reflective element). while remaining within the spirit and
`scope of the present invention).
`For example, the coating may comprise ruthenium or
`chromium or aluminum or aluminum alloy materials or the
`like. Optionally, the coatings may be sputter deposited on
`the substrate surface via a target. Typically, when the targets
`arc expended, ruthenium is repressed onto tl1e target (to save
`recycling costs) rather than regrinding the expended base of
`the target. Optionally, the targets may comprise chromium
`bases instead of ruthenium bases to reduce the inventory
`carrying costs of the targets. Thus, the target may comprise
`a low cost base material (such as chromium or the like), with
`a higber cost material (such as ruthenium or the like) pressed
`o nto the base, so that the target uses less of the high cost
`material and tlrns lies up a reduced amount of high cost
`material in the mirror manufacturer's inventory.
`As shown in FIG. 5. electrical co!lllections 36a, 36b may
`be established at co!lllection areas to provide electrical
`collllection to busbars or electrically conductive traces at a
`respective one of the front and rear substrates to provide
`electrical current to the electrically conductive coatings at
`the rear surface of the front substrate and the front surface
`
`8
`of the rear substrate for powering and dimming or varying
`the reflectance of the reflective element. Optionally. for
`example, and with reference to FIGS. 28 and 29, rwo or
`more (such as three or more) conductive epoxy patches 37a
`5 may be disposed along an
