Description

MIRROR MIRROR WITH SCREEN Field of the Invention The present invention relates to vehicle rear-view mirrors, and more particularly, refers to the display or presentation of information on top of a rear-view mirror assembly.

Antecedent-bes of the Invention Modern automobiles and transport trucks include rear-view mirrors mounted inside and outside the vehicle. A conventional type of interior rearview mirror comprises a prismatic mirror that can be changed from a convenient first orientation for normal driving conditions to a second orientation, which reduces the reflection produced by the headlights of the vehicles approaching from the later. Recently, electrochromic rear-view mirrors have been developed, which change, automatically, from a total reflectance mode during the day to a partial reflectance mode during the night for reflection or brightness protection. Typically, mirrors Ref: 128115 electro chromic mirrors comprise a relatively thin optical electrode that is interposed and sealed between two mirror elements. In most assemblies, when the electro-optical medium is electrically energized, it obscures and absorbs the increase in the amount of light as the applied voltage increases. When the electrical voltage is removed, the mirror returns to its state of clarity. Examples of automatic rear-view mirrors are described in U.S. Patent Nos. 4,902,108; 4,917,477; 5,128,799 5,202,787; 5,204,778; 5,278,693; 5,280,380; 5,282,077 5,285,060; 5,294,376; 5,682,267; 5,689,370; 5,448,397 5,451,822; and 5,818,625 each of which is assigned to the owner of the present invention, and each of which is incorporated herein by reference. In the past, information, such as the words "HEATED" or "THE OBJECTS IN THE MIRROR ARE CLOSER TO WHAT THEY LOOK LIKE", have been used in many vehicle rear-view mirrors. In addition, some types of automatic rear-view mirrors have included compasses and temperature readers. However, such conventional rear-view mirror screens typically comprise a bright flat surface, which makes the screen difficult to read. In addition, conventional displays are often difficult or impossible for some occupants of the vehicle to read. For example, interior rear-view mirrors are typically angled towards the driver and away from the passenger in the front seat, thus obstructing the ability of the front-seat passenger to see the screen. In addition, the selectable information screens that are commonly used inside automobiles comprise complex electronic assemblies. This type of screen is not only expensive, but also prone to fail due to the number and complexity of its components. In addition to the problems and issues discussed previously with the screens in the mirrors, there are additional problems that need to be addressed. One way to form the individual letters of the words "HEATED" and "THE OBJECTS IN THE MIRROR ..." is to apply reflective material to an electro chromic mirror sub-assembly as a uniform layer, and then selectively remove the parts. of the reflective material to form a profile or image of detailed numerical alphabetic characters and symbolic signs in the reflective material. However, it is difficult to remove the reflective material in a way that, accurately and consistently, forms all the parts of small letters and symbols, so that the potential process of removal results in significant waste. This waste can be very expensive because, not only does it represent a significant percentage of waste resulting from imperfect sign images, but also the mirror sub-assembly is a relatively expensive work process at this point in the manufacturing process. Concurrently, the residue is difficult to repair. Another problem is that, even if the reflective material is removed, precisely, to form the image of signs, many manufacturers want color on their screens to improve their attractiveness to the customer. In the past, translucent colored labels have been used, such as in the instrument panel, to create visual screens. However, there are problems with known labels of the prior art that are used in the environment of a mirror. For example, adhesive labels that use adhesive can be delaminated from the glass mirror element, partially, over time which leads to a poor appearance where the adhesive that comes off has a discontinuous appearance and patch or resane . Also, the adhesive can trap air during the installation process, which leads to an immediate poor appearance or delamination problems in service as its catalysts are in thermal cycles. The alignment of the components and the screens in the mirrors is another important consideration with respect to customer acceptance. Screen information that is not parallel and that is angled in relation to a perimeter of the mirror can result in the client forming a very poor opinion of the quality of a vehicle, even if the mirror is functional, totally. In addition, the misalignment can be very aggravating to customers, because customers observe the problem of misalignment every time they look at the mirror, which happens every time they are in the vehicle. Another problem is the precise placement and retention of a printed circuit board in the mirror housing. Printed circuit boards carry circuits that are used in electrochromic mirrors to control shadowing for brightness or reflection protection, and also carry other circuits and sensors, such as to detect daylight, to detect input signals without a keyboard , for information screens, and the like. It is important that the printed circuit board is placed, precisely so that any of the lighting sources and sensors carried by the board are placed exactly, and that any of the control buttons for the mirrors, which are mounted on the board of printed circuits and protruding through the surface of the housing, also be placed in their own way and in a precise manner. Additionally, it is noted that the printed circuit board must be firmly clamped in a way that prevents swaying, although in a way that does not lead to undue breakage, bending or bending or that the printed circuit board is subjected to efforts during assembly and during the thermal cycle as it is in service. Another less obvious problem concerns the secondary reflections and the diffusion of light within transparent layers in the mirror subassembly. The electro chromic mirror sub assemblies include a pair of transparent elements, such as flat glass elements, with a camera between them. The chamber is filled with electrochromic material that includes a first layer of transparent conductive material and any other transparent conductor layer (if the mirror sub-assembly is a fourth surface reflector), or a reflector / electrode (if the mirror sub-assembly) it is a third surface reflector). When light is introduced through an aperture in the reflection, a primary quantity of the light travels through the transparent elements and through the associated layers of electro chromic material without unacceptable distortion. However, a small amount of light is reflected as light passes through each of the interconnection surfaces in the mirror subassembly. This can lead to double images (sometimes called "ghosts"), blurry images, with shadow, and / or the occurrence of undesirable diffusion of light through the visible surface of the mirror subassembly. This is not desired, because it reduces the clarity of the display screen and can, in extreme cases, be interpreted as a defect by the client. The present invention has been developed in view of the foregoing, and is directed to other shortcomings of the prior art.

Detailed Description of the Preferred Modes Figure 1 is a schematic diagram illustrating a vehicle sensor and a display system 1 according to one embodiment of the present invention. The system 1 includes a passenger sensor 2, a passenger air bag controller 4, and a passenger air bag status display 6. Alternatively, the display system could include a manual bag disconnect switch of air in place, or in addition to, the passenger sensor 2 and the air bag controller 4. The passenger sensor 2 is used to determine if the passenger is located at a particular position in the vehicle. For example, the passenger sensor 2 can be used to determine whether a passenger is seated in the right front passenger seat of an automobile or the like. The passenger sensor 2 can be used to determine the approximate size of a passenger in order to allow deactivation of the passenger airbag if the passenger is smaller than a particular size. The sensor 2 can also be used to determine if an infant or child seat is present and to deactivate the air bag if such infant or child seat is detected. Examples of convenient passenger sensors 2 include conventional infrared sensors, pressure sensors, and the like.

As shown in Figure 1 the passenger sensor 2 is connected to the passenger air bag controller 4. Based on the signal provided by the passenger sensor 2, the controller 4 closes the passenger air bag circuit. passenger when a person of suitable size is placed in the passenger seat, and opens the circuit of the airbag when there is no passenger in the seat. Alternatively, the air bag status screen 6 can be connected directly to the passenger sensor 2. In addition, the air bag screen 6 can be connected with a manual air bag disconnect switch (not shown) ). The passenger air bag controller 4 is connected to the passenger air bag status screen 6, as shown in Figure 1, schematically. In accordance with the present invention, the passenger airbag status screen 6 is located in the rear view mirror assembly. The display 6 may include any convenient sign that alerts the occupants of the vehicle that the passenger's airbag is either active or inactive. For example, the display 6 could illuminate the words "PASSENGER AIR BAG DISCONNECTED" when the passenger airbag has been deactivated by the controller 4 or by means of a manual switch. Alternatively, the display 6 may include any other of the symbols and / or numerical alphabetic characters, which adequately transmit the information concerning the condition of the passenger airbag to at least one occupant of the vehicle. According to the preferred embodiment of the invention, the screen 6 is located in the rear view mirror assembly of a vehicle. In general, vehicle drivers observe in the interior rearview mirror very frequently. This frequent use provides an optimum position in the interior rearview mirror for the display of critical safety information, such as the condition of the airbag. When viewing safety information in the interior rearview mirror assembly, the driver or other occupants of the vehicle can be alert with critical information, which otherwise could not be noticed. Examples of suitable screens include light emitting diode (LED), vacuum fluorescent, and liquid crystal display (LDC) screens. The screen may comprise a filter with words such as "AIR BAG", an airbag symbol displayed on a surface, which would become more visible, more apparent, or change color when the screen was illuminated or illuminated to backlight, or may comprise an indicator light or series of lights in a position relative to a symbol or text indicative of an airbag, announcing the activation or deactivation of the airbag system by means of a change of status or color of the (s) light (lights). These indicators and screens could be located in the mounting that supports and covers the mirror, in a module supported by, although it is not integral with the mirror assembly, or in the mirror surface, as it is going to be described in its entirety. continuation. Figure 2 is a front elevation view of a rearview mirror 10 according to one embodiment of the present invention. The rearview mirror 10 includes a mirror surface 11 surrounded by a bevel 12. In the embodiment shown in Figure 2, the rearview mirror 10 is an automatic interior electro chromic mirror. However, other types of rear-view mirrors may be provided including exterior mirrors and prismatic interior mirrors according to the present invention. As shown in Figure 2, a chin 13 is located on the bottom of the bevel 12. A switch 14 can be provided inside the chin 13 in order to turn on and off the automatic electrochromic auto rearview mirror 10. A conventional sensor of light 15 can be located on the chin 13 or in any other convenient position. In addition, an indicator 16 located on the chin 13 is used to indicate whether the electro chromic rearview mirror 10 is on or off. Typically, the indicator 16 includes a light, which is illuminated when the electro chromic rearview mirror 10 is turned on. In the embodiment of Figure 2, a passenger air bag status screen 18 is located on the mirror surface 11. The display 18 includes the words "PASSENGER AIR BAG DISCONNECTED". However, any other convenient signs, either symbolic or alphabetical, may be used, which adequately convey the condition of the passenger airbag. In the case of the mirror surface screen 18, any convenient screen can be located in or behind the mirror to observe through the mirror assembly. The screen 18 may comprise a substantially transparent section in the mirror. Part or all of the reflective surface of a selected area can be removed. An indicator light source is placed behind the selected area. The removal or removal of any of the other opaque elements in the area mentioned above is also desirable so that the indicator or screen can be observed through the mirror. The removal of the reflective surface could create an indicator graph trajectory where desired. For example, the words "PASSENGER AIR BAG DISCONNECTED" could be recorded outside the reflective surface, partially or completely to allow the transmission of light from a light source through the graphic path to thereby indicate the state of the system. airbag. Figure 3 is a side sectional view, in partial outline showing a type of rearview mirror display assembly 20 that can be used in the rearview mirror 11 of Figure 2. The rear view mirror screen assembly 20 includes a first glass sheet 21, which forms a visual or observation surface that faces the occupant of the vehicle. The observation surface of the first glass sheet 21 can be smooth or can be provided with a matte texture. A second glass sheet 22 is separated from the first glass sheet 21.

An electrically conductive, substantially transparent layer 23 covers the inner side portion of the first glass sheet 21, in accordance with another electrically conductive, substantially transparent layer 24 covers the inside of the second glass sheet 22. An electro composition chromic 25 fills the space between the glass sheets 21 and 22. A reflective layer 26 made of any convenient material, such as silver, is provided on the surface of the second glass sheet. The screen assembly 20 is provided as a part of an electro chromic rear view mirror. The various components of the electrochromic rear view mirror can be arranged and constructed as described in the previously cited US patents which are incorporated herein by reference. As shown in Figure 3, a portion of the reflective layer 26 is removed from the glass sheet 22 in order to provide an opening 27. A sign panel 28 covers the opening 27. A light source 29 is positioned that in illumination, the light travels through the sign panel 28, the aperture 27, and the remaining layers 21-25 of the electrochromic mirror assembly toward the vehicle occupant. The sign panel 28 may be unmarked or may comprise any desired signs, such as numeric alphabetic symbols or the like. Optionally, the sign panel 28 may comprise a color filter. The light source 29 may comprise any convenient type of illuminator, such as an LED, an LCD, a vacuum fluorescent element, an incandescent light, or the like. The screen 18 may be part of the silver lining that is engraved / removed to form individual letters or components of the graphics through which the light passes to illuminate the letters or graphics. In addition, the screen 18 may comprise printed legends or graphics or else they could be applied to a free or clear area on the silver where the graphics or legends would be of a design to show contrast when they are illuminated. The graphics or screen can be separated from the mirror element mounted behind the element, such as a conventional liquid crystal display (LCD), a fluorescent vacuum screen, a static masking through which the light will pass to visualize the graphs or legends , or other types of screens. Optionally, a color filter can be included between the light source of the screen and the observer, such as a color filter printed or attached to the mirror surface, or a filter installed on the light source, or at any point between they. The light source could also be of a narrower bandwidth than the total spectrum of visible light for the purpose of displaying a different color through the screen graphics to indicate the state of the airbag system. In the versions that require the removal of something from the silver surface a part more than all the silver can be removed in one area and still allows the screen to be observed. One method is to remove a model such as a grid. This allows conduction through a substantial amount of the surface that facilitates coloring and cleaning the electrochromic substance in that area proportional to the rest of the element. Another method is to allow the letters and graphics to be undone to avoid closed sections on the surface. In the embodiment of Figure 2, the surface of the screen 18 is flush with the surface of the mirror 11. Alternatively, the surface of the screen 18 may be non-planar. For example, the surface of the screen 18 may comprise a convex arc extending from the surface of the mirror 11. In accordance with a preferred embodiment of the present invention, a non-planar screen is provided on the rear view mirror assembly. As used in this document, the term "non-planar screen" means a screen having a contoured outer visual surface instead of a flat outer surface. Preferred surfaces of non-planar contoured screens include curved or convex facet configurations. Figures 4-6 illustrate a rearview mirror 30 having a non-planar screen according to a preferred embodiment of the present invention. The rearview mirror 30 is an automatic electrochromic mirror that includes a mirror surface 31 and a bezel 32. Although an electrochromic mirror is shown in Figures 4-6, other types of mirrors, such as prismatic mirrors, are within the scope of the present invention. A contoured chin 33 having a curved front face is located at the bottom of the bevel 32. Contoured chin 33 houses a compass switch 34, a mirror switch 35, a light sensor 36, and an on / off indicator 37. In this embodiment, a non-planar screen 38 is located on the chin 33. As shown, more clearly, in Figure 5, the surface of the non-planar screen 38 is convex and forms the contoured surface of the chin. 33. The use of the convex non-planar screen 38 substantially provides improved visibility of the information provided by the screen. The curved outer surface of the screen 38 essentially prevents the shine or unwanted reflection of the surrounding light sources and provides improved visibility to the occupants of the vehicle. For example, both the driver and the front passenger (s) of the vehicle can easily read the information provided by the screen 38 without obstruction. In a preferred embodiment, the non-planar surface of the screen 38 has a matte texture in order to reduce unwanted brightness. A screen, such as a vacuum fluorescent screen, an LCD, an LED, or the like can be mounted on the bezel or, preferably, behind a filter on the bezel. A static screen can be illuminated simply or the lighting color can be changed to display the information. This screen offers different possible configurations. A preferred screen comprises an opening in the bezel and a mask or label with graphics and / or printed signs on the surface to allow light to pass through the part of the legend or graphics on the label. You can use legends or graphics molded or engraved on the bezel through which the light could pass to illuminate the legend or graphic. You can also use a translucent bezel or part of the bezel on which graphics could be painted or printed to allow light to pass through only certain parts. In addition, printed or molded graphs or legends with a corresponding translucent or open section through which light could pass to indicate the state can be used. In addition, a graphic status screen and / or legend can be used with a corresponding light which illuminates or changes the color. In the embodiment shown in Figures 4-6, the rearview mirror 30 includes a compass reader 39, which indicates the direction in which the vehicle is oriented. The compass switch 34 can be used to turn the compass reader 39 on and off. As shown, more clearly, in Figures 5 and 6, the rearview mirror 30 includes a housing 41 and a conventional mounting bracket 42. However, other mounting methods can be used. Figures 7 and 8 illustrate a rearview mirror 50 according to another embodiment of the present invention. The electro-chromic rearview mirror 50 includes a mirror surface 51 and a surrounding bevel 52. A chin 53 having, generally, a flat front face extends from the bottom of the bezel 52. The chin 53 houses a switch of compass 54, a mirror switch 55, a light sensor 56, and an on / off indicator 57. A convex non-planar screen 58 extends from the surface of the chin 53. A compass screen window 59 is provided. on the mirror surface 51. The rearview mirror 51 also includes a housing 61. The convex surface of the non-planar screen 58 shown in Figures 7 and 8 substantially improves the visibility of the message displayed. Figures 9 and 10 illustrate a rearview mirror according to a further embodiment of the present invention. The electro chromic rearview mirror 70 includes a mirror surface 71 surrounded by a bevel 72. A chin 73 is located in the lower part of the bevel 72 and includes a mirror switch 74., a light sensor 75, and an on / off mirror indicator 76. A crown or arc 77 having a substantially planar front surface is located at the top of the bevel 72. A convex non-planar screen 78 is located in the crown or arch 77. The rearview mirror 70 also includes a housing 81. Figures 11 and 12 illustrate another rearview mirror 90 according to a further embodiment of the present invention. The rearview mirror 90 includes a mirror surface 91 surrounded by a bevel 92. A chin 93 that is located on the bottom of the bezel 92 houses a mirror switch 94, a light sensor 95 and a mirror indicator on / off 96. The right side of the bevel 92 includes an extension 97 having a non-planar screen 98 at that location. The rearview mirror 90 comprises a housing 99. In this embodiment, the non-planar screen 98 is oriented, so that a passenger seated in the front right seat of a vehicle can easily see whether the passenger's air bag or mattress is on or switched off Figure 13 is a side elevational view, in partial outline illustrating a non-planar rear view mirror screen assembly 100 according to one embodiment of the present invention. The non-planar screen assembly 100 includes an electro chromic mirror assembly, which comprises a first glass sheet 101, a second glass sheet 102 separated from the first glass sheet 101, and an electro chromic material 103 that fills the space between the glass sheets 101 and 102. A seal 104 extends between the glass sheets 101 and 102 in order to retain the electro chromic material 103 between them. Although not shown in Figure 13 the electro chromic mirror assembly can including electrically conductive, substantially transparent conductive films on the inner surfaces of the glass sheets 101 and 102, and may comprise a reflective mirror surface positioned in any convenient position, such as the outer surface of the second glass sheet 102. Convenient types of electrochromic rearview mirror assemblies are described in the aforementioned US patents, which are incorporated herein by reference. This document by reference. As shown in Figure 13, a bevel 105 contacts the outer viewing surface of the first glass sheet 101 of the electro chromic mirror assembly. A lamp holder 106 having a reflective interior surface is formed in the bevel 105. A light source assembly 107 is secured in the lamp holder 106. in the embodiment shown in Figure 13, a LED light emitting diode 108 is provided as part of the light source assembly 107. Alternatively, any other convenient source of light, such as an electro-luminescent source, an incandescent light, or the like may be used. A sign panel 109 covers the lamp holder 106. The sign panel 109 forms the outer visual surface of the screen. In accordance with the preferred embodiment of the present invention, the sign panel 109 comprises a convex exterior visual surface defined by at least one radius of curvature, as will be described, more fully below. The sign panel 109 shown in the Figure 13 may be unmarked or may comprise any of the desired graphics, alphabetic number symbols, or the like. Optionally, sign panel 109 may include a color filter. The preferred non-planar screens of the present invention comprise a convex outer observation surface, which is defined by at least one radius of curvature. The radius of curvature may be constant or may vary along the outer surface of the screen. For example, in the embodiments shown in Figures 4-10, the non-planar displays have an outer curved surface of a substantially constant radius defined by an arc sweep around a substantially vertical axis. Such arcs are more easily observed in Figure 8, the element 58 and in Figure 10, the element 78. The radius of the arc, typically, runs from about 1 cm to about 60 cm, and more preferably, from about 1.5 cm to about 15 cm. This geometry results in a screen, which is easily observed by all occupants of the vehicle as it reduces unwanted brightness. In the embodiments of Figures 11 and 12, the non-planar display has a variation of radii of curvature, which substantially conform to the curved bevel surface of the mirror. The non-flat screen reduces brightness or reflection and is observable, easier for at least the right front passenger of the vehicle. Conventional flat screens have a high degree of reflection of the first surface that decreases the contrast between the graphs on the screen, which are intended to be observed and reflect the light of the surface. This degrades the ability of the passenger to observe the displayed information, because the passenger of the front seat sits, in a usual way, in a position that can create an observation angle of up to 30 degrees or more outside the line perpendicular to the mirror front surface. A non-flat screen, as well as surface treatment such as a matte finish, decreases the reflection of the surface, increases the contrast of the screen, especially when viewed at an angle. The curvature of the screen also serves to orient the screen or a part of the screen towards the passenger and, therefore, improves the visibility of the screen. A low gloss surface and a convex surface has the added benefit of reducing the brightness or reflection of the viewing surface for the driver and other occupants of the vehicle. Additionally, because the display or display surface is, typically at the same angle as the mirror surface, the brightness of the headlights of the next vehicle can also give a bright, incomprehensible flat screen.

Although the non-flat screens described in the modalities specified in this document are used to transmit information concerning the status of a passenger airbag, other types of symbolic or alphabetical numerical information may be displayed in the rearview mirror assemblies in accordance with the present invention. For example, the status of the other airbags or supplementary restraint systems in the vehicle can be displayed. In addition, information such as doors between open, seat belts, fuel mileage, time, temperature, orientation or heading, altitude, and the like can be displayed.

MODIFICATION A mirror assembly 115 (also referred to herein as "mirror 115") (Figures 14 and 15) includes a • housing 116 and a bevel 117 that defines a cavity 118, and also includes a sub-assembly of electro chromic mirror 120 (Figure 25) which is supported in the cavity 118 together with a printed circuit board 119. The printed circuit board 119 has a circuit that is configured to operate the electro chromic mirror sub-assembly 120 for controlled dimming that reduces brightness or reflection in the mirror 115. A sign panel 130 (sometimes called "applied") is attached to a rear part of the mirror sub-assembly 120 or the 117 bevel to provide a low cost, a highly attractive illuminated screen on the mirror 115. The sign panel 130 is constructed to be attractive and effective, exceptionally, as described below. The sign panel 130 is constructed with centering or reference clutch details that facilitate alignment in the mirror sub-assembly 120, and further provides alignment of the mirror sub-assembly 120 on the bevel 117 and in the housing 116, as also further described. ahead. The electrochromic mirror sub-assembly illustrated 120 is commonly referred to as a fourth surface reflector, although it is contemplated that the present invention will work well with the third surface reflector and the other mirror constructions. Accordingly, it is contemplated that one scope of the present invention includes all mirror constructions and the present disclosure should not be constructed as an unnecessary limit. The mirror sub-assembly illustrated 120 (Figure 5) includes front and rear transparent elements 121 and 122 (for example, glass), electrically conductive layers 123 and 124 on the inner surfaces of the transparent elements 121 and 122, respectively, a layer of electro chromic material 125 which is located between the conductive layers 123 and 124, and a reflective layer 126 on a rear surface of the rear transparent element 122 (ie, the "fourth" surface of the mirror sub-assembly 120. A seal 125 'extends around the inner perimeter of the transparent elements 121 and 122 for retaining the electrochromic material 125, when the electrochromic material 125 is in a liquid phase type, or in a gel phase type, or in a hybrid thereof, (it is observed that the perimeter edge which is peeled off can be applied to the transparent elements 121 and 122 for aesthetics, which results in a similar appearance.) A portion of the reflective layer 126 is graveled out or otherwise. nera is removed to define an elongated opening 127 (Figure 18). The sign panel 130 adheres to the reflective layer 126 in a position where it covers the opening 127. The light sources 129 are positioned behind the sign panel 130 to pass light through the sign panel 130 and through the opening 127 of the electro chromic mirror sub-assembly 120 to selectively illuminate the detailed symbols and information on the sign panel 130 to be observed by the driver of the vehicle or passengers. A foam light seal 134 on the sign panel is located between the printed circuit board 119 and the sign panel 130, and is formed (see Figure 16) to engage, in a sealed manner, the printed circuit board 119 and the sign panel 130 for preventing scattering or light leakage around the sign panel 130. Specifically, the foam light stamp 134 defines multiple windows 146 '-148' (Figure 23) that engage the sign panel 130 to contain the light from each of the light sources 129 (Figure 17) as each window area is illuminated. The housing 116 and the bevel 117 are disengaged together and formed to compress together the mirror sub-assembly 120, the sign panel 130, the printed circuit board 119, and the light seal 134, thereby compressing the light seal 134 to ensure good contact by the light seal 134. It is contemplated that the present invention includes many different sign panels constructed of light absorbent material to absorb unwanted diffuse light and reflections, and that they are also constructed with recessed tabs. reference contact or centering and centering characteristics. The sign panel illustrated 130 (Figure 23) includes a body panel 140 of translucent light-passing material or transparent material, such as a mylar sheet, having a rectangular main section 141 and tabs angled downwardly 142 at each end. The body panel 140 includes a front surface treated to minimize the degree to which it will show fingerprints, as is known in the art. A reference or centering position or hole feature 143 is formed in each tab 142. The holes 143 are configured to engage with centering profusions in a fixed part (not shown specifically, but shown in Figure 23) to provide a very precise alignment of the sign panel 130 on the mirror sub-assembly 120 when the sign panel 130 adheres to a rear surface of the mirror sub-assembly 120. The centering holes 143 are further configured to engage with a pair of centering profusions. 170 on the bevel 117 to very precisely position the mirror sub-assembly 120 (includes the sign panel 130) on the bevel 117 and the mirror housing 116 as described below. When the adhesive layer is removed, the reference or center holes engage with the profusions 170 for alignment of the sign panel 130, according to another structure in the housing 116 and in the bevel 117 aligns the mirror sub-assembly 120. An absorbent layer of light 145 of ink, film, paint, or the like, is applied to the rear surface of the body panel 140. The light absorbing layer 145 accurately and relatively accurately forms small, well-defined windows 146-148 on the body panel 140. One or more layers of semi-transparent material or translucent material 149-153 are applied on top of the body panel 140 in the area of windows 146-148 to form the signs of the current visual screen. It is contemplated that the materials 149-153 have properties that allow them to be applied accurately to form detailed symbols, such as by means of the known processes of printing and symbol formation and the film application process. For example, it is contemplated that the ink could be applied by means of a multiple coating printing process or even by means of an ink jet printing machine or by means of a copy / duplicate machine. The illustrated black material 149 includes openings that form clear legends. The layer 150 is applied behind the clear legend and is translucent white, so that the words "PASSENGER AIR BAG" appear when the window 146 is illuminated. The material 151 is also white and is shown through as a symbol of a person with an inflated air pocket in the front of a person, although it is contemplated that the material 151 could in fact be colored (eg, orange or red) to enhance and distinguish the symbols. The materials 152 and 153 form letters for the words "on" and "off", which are visible only when the individual windows 147 or 148 are illuminated. In the sign panel illustrated 130, an elongate layer 155 (Figure 23) of adhesive having a small vertical dimension is applied to one face of the body panel 140 along an upper edge above the windows 146- 148, with the ends of the layer 155 extending, partially, downwards along an upper edge of the tabs at a downward angle 142 to delineate a concave adhesion area on all three sides of the signs which form the visible screen. This concave arrangement helps to avoid trapped air when the sign panel 130 adheres to the mirror sub-assembly 120. This also helps to reduce thermal expansion problems by providing an area in which the body panel 140 can be expanded or flexed. . The adhesive layer 155 is covered with a release paper 156 to protect the adhesive during shipping and handling before it is assembled. Seal 134 (Figure 23) includes a piece of compressible foam 157 and further includes a face covered with adhesive 158 that adheres adherently with the back of light absorbing layer 145 on body panel 140 of the panel of signs 130. The compressible foam 157 has the windows 146 '-148' cut into the foam that is aligned with the windows 146 '-148' in the light absorbing layer 145. The bevel 117 (Figures 17 and 18), of Generally, it is oval in shape and is configured to surround and to engage, in a receiving and coupled manner, a perimeter of the mirror sub-assembly 120. A lower horizontal section (Figure 6) of the bevel 117 includes the upper and lower portions 161 and 162 that they form a window for receiving switches or buttons 160 operated by fingers in the mirror 115. This part of the bevel 117 that engages the perimeter of the mirror sub-assembly 120 includes a rearwardly extending interior section 163, which engages with a face of the element or front transparent 121, with an aesthetically formed transition area or front portion 164, and with an external rearwardly extending side section 165, which extends at least to an adjacent position of an edge of the mirror sub-assembly 120. This part of the bezel 117 that engages the housing 116 includes a flange or leg that extends rearwardly 166, which defines a cavity that faces outwards 167. The housing 116 includes a forwardly extending section 168, which fits into the cavity 167 and engages, superimposed, with the flange or leg 166. the bevel 117 includes a hook-shaped connector 169 (Figure 17) that is constructed to engage frictionally fast in the recess 169 'in the housing 116. The guide fingers 169"extend from the housing 116 at positions adjacent to the hook-shaped connectors 169. The fingers 169" are formed to engage with a back surface of the flange 166 in a manner that forces the hook-shaped connector 169 toward a secure clutch with the recess 169 '. It is contemplated that the hook-shaped connector 169 and the recess 169 'may be inverted in the housing 116 and the bevel 117, or that they may be replaced with other connecting means, such as screws, mechanical fasteners, adhesive, sonic welding, and similar.

The bevel 117 (Figure 18) includes a pair of reference protrusions or rearward protruding 170 spaced apart on each side of the sign panel 130. The profusions 170 are formed to engage with the holes 143 in the tabs 142 for positioning, of Precisely, the sign panel 130 relative to the bevel 117. This is very important because the signs (ie, the legend and the symbols) in the sign panel 130 must be aligned very precisely with the 117 bevel for avoid the appearance of misalignment and poor quality. Because the sign panel 130 adheres precisely, with the sub-assembly of mirrors 120, the profusions 170 cause the mirror sub-assembly 120 (including the visible interior of the seal 134) to also align, precisely, with the bevel 117. Notably, it is specifically contemplated that the adhesive layer 155 can be removed. In such a case, the profusions 170 precisely position the sign panel 130, with the projections and other structures of the housing 116 and the bevel 117 they accurately position the mirror sub-assembly 120. The printed circuit board 119 (Figure 18) includes centering openings or holes 173 which also engage the profusions 170 to accurately position the printed circuit board 119. The illustrated light sources 129, which may be any convenient type of illuminator, such as LED, LCD, vacuum fluorescent elements, incandescent lights, or the like, are mounted to the printed circuit board 119. However, it is contemplated that the light sources 129 could be mounted behind the printed circuit board 119 and shine through the windows in the printed circuit board 119. The switches 160 are also mounted to the printed circuit board 119 in a position where it is aligned with the lower windows on the 117 bezel, and where they are easy to operate by a seated driver. The housing 116 (Figure 17) includes side walls 176 having the recesses 169 'and the guide fingers 169"that receive the hook-shaped connectors 169, and further includes a rear wall 177. The rear wall 177 includes a structure assembly 178 for engaging, in an adjustable manner, and operably, with the vehicle ball assembly 179 (Figure 15). The projections 180 (Figure 16) extend forward from the rear wall 177 towards a contact clutch with the printed circuit board 119. When assembled, the bevel 117 quickly attaches to the housing 116 to compress the sub-assembly together of mirror 120, sign panel 130, printed circuit board 119, and light seal 134 in a sandwich-like compressed arrangement, with light stamp 134 compressed, illuminated. As shown by means of Figure 24, the mounting method includes printing and forming the sign panel 130 in a step 183, and then adhering the foam light stamp 134 with the sign panel 130 in the step 184. In step 185, the mirror sub-assembly 120 is fixed by means of a position clutch of its reference or center holes 143, and the sign panel 130 is attached, precisely, to the sub-assembly of mirrors 120 (if adhesive is used) removing the release paper 156 and adhering the adhesive 155 to a rear surface of the rear transparent element 122 as the sign panel 130 is precisely held. The sign panel 130 is then used to accurately position the sub-assembly of mirrors 120 with the bevel 117 by registering the holes 143 in the profusions 170 of the bevel 117 in a step 186. Alternately, where the adhesive layer 155, the profusions 170 engage with the holes 143 to position the sign panel 130, although the mirror sub-assembly 120 is positioned by means of the clutch with the bevel 117 and the housing 116. The printed circuit board 119 is also it positions, precisely, when registering its holes 173 in the profusions 170 in a step 187. The housing 116 quickly attaches to the bevel 117 in step 188. This causes the contact or support projections 180 in the housing 116 clutch to the printed circuit board 119, compressing the foam light seal 134 between the printed circuit board 119 and the sign panel 130, and compress the sign panel 130 with the light pressure against the mirror sub-assembly 120. This light pressure helps to maintain the sign panel 130 against the mirror sub-assembly 120, still allowing for dimensional variation during assembly. This arrangement also allows the expansion and contraction that occurs during the thermal cycle of the mirror 115 as it is in service. An important benefit of using a light absorbing sign panel 130 is shown in Figure 25. The light source 129 emits light 190, a primary part 191 of which, travels through the sign panel 130, through the aperture. 127, and out through various components of the 120 mirror submount to a person observing. The secondary reflections 192-195 occur on the rear surface of the rear transparent element 122, and on each interface between the layers 122/124, 124/125, 125/123, and 123/121. These secondary reflections 192-195 are absorbed by means of the light absorbing layer 145 in sign panel 130. This arrangement greatly reduces unwanted diffuse light. The size of each window 146-148 and of the windows 146 '-148' (see Figures 16-18 and 23), and also the size of the opening 127 (Figure 25), are chosen to optimize the clarity of the image projected by the primary light part 191 without fogging the reflected images of the mirror 115. In a preferred form, the vertical dimension of the letters and symbols is about 25 percent up to about 75 percent, or more preferably around 50 percent, of the vertical dimension of the opening 127. It is noted that the mirror sub-assemblies 120 having the same opening size 127 can be used in the mirrors 115 having different options. For example, a different sign panel 130 may be used in conjunction with different printed circuit boards 119, as the same bevel 117, housing 116, and mirror sub-assembly 120 are still used. This greatly facilitates the manufacture of high volumes of sub-assemblies. 120 mirror still allows a maximum of options. In addition, the same housing 116 and the same mirror sub-assembly 120 can be used, as a different bevel 117 is used. This is a major advantage because the mirror sub-assembly 120 is one of the most expensive mirror 115 components. It is important to allow the mirror sub-assembly 120 to be in higher volumes to optimize the automation of the manufacturing process and to minimize costs. It is specifically contemplated that the aspects of the present invention may be used, advantageously, in different mirror constructions. One such mirror, is illustrated in Figure 26, and includes a sign panel that mounts to the front portion 130 A, which adheres, adherently, to a front surface of the front transparent element 121. In the mirror 115A, the components and features that are identical or similar with the features and components of the mirror 115 are identified by the same number, although with the addition of the letter A. In the mirror 115A, the sign panel 130A adheres with the surface front panel using adhesive 155A, and light absorbing layer 145A is located adjacent to adhesive 155A. Notably, it is contemplated that the adhesive 155A could be omitted, where the sign panel 130A is suitably supported by the bevel portions 117A. It is also contemplated that the light absorbing layer 145A could be placed on the other side of the sign panel 130A or even on any of the front or back surfaces of the transparent elements 121 and 122. The sign panel 130A provides many of the advantages previously perceived, including the advantages of fixation, good looks, low costs, and a flexible part that can be used in mirrors that have different options. In the foregoing description, it will be readily appreciated by those skilled in the art that modifications to the invention can be made without departing from the concepts described in this document. Such modifications are to be considered and included in the following claims, unless these claims expressly express otherwise to the contrary.

It is noted that in relation to this date, the best method known by the applicant to carry out the aforementioned invention is that which is clear from the present description of the invention.
