A method for producing such a backing plate unit and a rear view device with such a backing plate unit are also described. ## Claims ### Claim 1 A backing plate unit for a rear view device for a motor vehicle, comprising: a backing plate; at least one opening passing from a rear side of the backing plate to a front side of the backing plate to form a logo pattern; a first attachment means on the rear side of the backing plate for a light source; and at least one of a light filter means and at least one extension in a region of the logo pattern, wherein the at least one of the light filter means and the at least one extension is extending from the front side of the backing plate. ### Claim 2 (depends on 1) The backing plate unit of claim 1, wherein at least one of the logo pattern is provided by one opening forming an icon or a plurality of openings forming an icon, and each opening forming the logo pattern is passing through the at least one extension. ### Claim 3 (depends on 1) The backing plate unit of claim 1, wherein the first attachment means comprises at least one of: supporting means comprising spigots on the rear side (112) for supporting the light source and a PCB thereof, and a mounting structure for a snap connection comprising at least one of at least one wall and clips on the rear side for holding the light source and the PCB on the supporting means. ### Claim 4 (depends on 1) The backing plate unit of one of claim 1, wherein the at least one extension is arranged in the region of the first attachment means and the region of the mounting structure between two walls. ### Claim 5 (depends on 1) The backing plate unit of one of claim 1, wherein second attachment means for an actuator of a reflective element are provided on the rear side of the backing plate, the second attachment means comprising a mounting structure for a snap connection. ### Claim 6 (depends on 1) The backing plate unit of one of claim 1, wherein the light filter means comprises a wooden pulp filter. ### Claim 7 (depends on 6) The backing plate unit of claim 6, wherein the wooden pulp filter is placed on the rear side of the backing plate, the PCB is placed on the rear side of the wooden pulp filter, a coat is placed on the rear side of the PCB, and at least a part of the rear side of the backing plate is surrounding the PCB. ### Claim 8 (depends on 6) The backing plate unit of claim 6, wherein the wooden pulp filter is placed on the front side of the backing plate, a coat is placed on the front side of the wooden pulp filter, and at least a part of the front side of the backing plate surrounds the wooden pulp filter. ### Claim 9 A method for producing a backing plate unit comprising: providing a backing plate unit for a rear view device for a motor vehicle, comprising: a backing plate; at least one opening passing from a rear side of the backing plate to a front side of the backing plate to form a logo pattern; a first attachment means on the rear side of the backing plate for a light source; at least one of a light filter means and at least one extension in a region of the logo pattern, wherein the at least one of the light filter means and the at least one extension is extending from the front side of the backing plate; and forming the backing plate together with the logo pattern and the first attachment means in a first molding step by injection molding. ### Claim 10 (depends on 9) The method of claim 9, wherein the forming of the backing plate further comprises forming the backing plate together with the logo pattern, the first attachment means, and a second attachment means in a first molding step, by injection molding. ### Claim 11 (depends on 9) The method of claim 9, further comprising securing the light filter means to the backing plate in a second molding or a coating step. ### Claim 12 A rear view device, comprising: a backing plate unit for a rear view device for a motor vehicle, comprising: a backing plate; at least one opening passing from a rear side of the backing plate to a front side of the backing plate to form a logo pattern; a first attachment means on the rear side of the backing plate for a light source; and at least one of a light filter means and at least one extension in a region of the logo pattern, wherein the at least one of the light filter means and the at least one extension is extending from the front side of the backing plate; a reflective element being attached to the front side of the backing plate; and a light source as well as an actuator being attached to the rear side of the backing plate. ### Claim 13 (depends on 12) The rear view device of claim 12, wherein the reflective element comprises a mirror glass or a transparent substrate including a glass element (310), with a translucent coating comprising chrome on its rear side. ### Claim 14 (depends on 12) The rear view device of claim 12, wherein the light filter means comprises a wooden pulp filter and is arranged either between the front side of the backing plate and the reflective element or between the rear side of the backing plate and the light source and a PCB thereof. ### Claim 15 (depends on 14) The rear view device of claim 14, wherein the reflective element is attached via a coating securing the wooden pulp filter on the backing plate. ### Claim 16 (depends on 12) The rear view device of claim 12, wherein a heater pad is arranged between the reflective element and the backing plate with the heater pad being provided with an opening through which at least one of the light filter means and the at least one extension extend. ### Claim 17 (depends on 12) The rear view device of claim 12, wherein: the extension abuts against the reflective element, or a gap is provided between the extension and the reflective element, with the gap being smaller than 1.25 mm and between 0.01 mm and 1.25 mm.
