DETAILED DESCRIPTION

[0035] The following detailed description is merely exemplary in nature and is not intended to limit the invention or the application and uses of the invention. Furthermore, there is no intention to be bound by any theory presented in the preceding background of the invention or the following detailed description.

[0036] FIG. 1 illustrates a side view of a motor vehicle in the form a passenger car. The motor vehicle 1 has a motor vehicle body 2 with an interior 3 that serving as a passenger compartment. The interior 3 is bordered by a glass panel forming a windshield 4 toward the front, when viewed in the traveling direction of the motor vehicle 1. An instrument panel 5 schematically depicted in FIG. 2 and/or a corresponding motor vehicle interior trim 5 is located below the windshield 4 in the interior 3, particularly below a mount or base area of the windshield.

[0037] With a gasket 8, the window 4 rests on a window support 7 of the motor vehicle body 2 that acts as a cross member. A holder 50 is arranged on the window support 7. In the illustrated embodiment, the window support 7 has a roughly U- or C-shaped geometry. The holder 50 is provided with a second induction element 124 on an end section facing away from the window support 7. This is located in a gap 12 between the lower front end of the instrument panel 5 and an upper end of the window support 7. With the window 4 installed, this gap 12 is largely inaccessible.

[0038] A display device 10 shown in cross section in FIG. 2 and from above in FIG. 3 is arranged on an inner side 11 of the window 4. The display device 10 has a carrier 22 with a largely flat and even configuration. A rear side 23 of the carrier 22 is provided with at least one splice 43. The rear side 23 of the carrier 22 can also be completely provided with one or several splices 43, or be coated by an adhesive layer configured to fasten the carrier 22 of the display device 10 on the inner side 11 of the window 4.

[0039] A first induction element 24 is arranged on a front side 21 facing away from the rear side 23, and in the finally assembled configuration shown in FIG. 2 comes to lie in the operating area of the second induction element 124. As depicted in FIG. 2, the first induction element 24 and second induction element 124 align with each other extensively in terms of area. The elements 24, 124 are arranged in the direction of the surface normal of the window 4 at a prescribed distance from each other. The operating area of the first and second induction elements 24, 124 further enables an electrical connection that compensates for installation tolerances. The precise position of the first induction element 24 relative to the second induction element 124 can vary within prescribed tolerances, which are significantly larger than the installation tolerances to be observed for the window 4 relative to the motor vehicle body 2.

[0040] The first induction element 24 may be inductively coupled with the second induction element 124. The second induction element 124 is connected by a cable 125 with the electrical system 126 of the motor vehicle 1, and hence also with a motor vehicle control device.

[0041] At least one electrical conductor 26 is arranged on the front side 21 of the carrier 22. The first induction element 24 is located on a second end section 16 of the elongated carrier 22. An electronic display 28 is arranged on an opposing first end section 14 of the carrier 22. The electronic display 28 is connected with the first induction element 24 in an electrically conductive manner by the electrical conductor 26. Finally, the electronic display 28 is connected with the electrical system 126 of the motor vehicle 1 via the inductive coupling of the first induction element 24 and second induction element 124.

[0042] In the present exemplary embodiment, the electronic display 28 includes a board 40 with several light sources 29 arranged thereon. The individual light sources 29 are shown in particular in FIG. 3 and FIG. 4. Involved in the present case are individual LEDs, which are arranged uniformly spaced apart along a line on the board 40. The board 40 may be detachably arranged on the carrier 22 by a counter-fastening element 42. To this end, the carrier 22 may have at least one fastening element 27, which is configured correspondingly to the counter-fastening element 42 of the board 40. The fastening element 27 and counter-fastening element 42 can include a latching or snap connection, and consequently a positive connection.

[0043] The board 40 may be connected via a plug connection with the electrical conductor 26, which is fixedly arranged on the carrier 22 as a flat cable or conducting path. This enables a replaceable arrangement of the electronic display 28, and thus of board 40, on the carrier 22. The electronic display 28 may further be provided with a housing 30. The housing 30 may cover the entire electronic display or entire board 40 and all light sources 29 arranged herein, and protect them against environmental influences.

[0044] As shown in FIG. 4, the housing 30 may be provided with a transparent window 32, so that the light that can be generated by the light sources 29 is able to exit the housing 30 through the window and radiate into the interior 3. In particular, the window 32 may be configured as a diffuser, so that the individual point light sources 29 cannot be separately perceived by the passengers.

[0045] As also shown in FIG. 4, the housing 30 may have a connecting element 35, which can interact with a carrier-side connecting element 25. The two connecting elements 25 and 35 may be correspondingly configured relative to each other in such a way as to yield a snap or latching connection. The connecting elements 25, 35 may be configured as corresponding intermeshing latching tabs or snap hooks. This permits a removable arrangement of the housing 30 on the carrier 22.

[0046] As depicted in FIG. 3, the carrier 22, and thus the entire display device 10, has a T-shaped or double-T-shaped basic geometry. The illustration in FIG. 3 presents a top view of the display device 10 in viewing direction B, as denoted in FIG. 2 with an arrow. The first end section 14 can be spread out perpendicular to the longitudinal direction of the carrier 22, so that the individual light sources 29 are spaced apart from each other roughly along the progression of the window edge 6. Provided between the first and second end sections 14, 16 is an intermediate section 15 with a tapered design. The intermediate section 15 is configured to establish a mechanical connection between the first and second end sections 14, 16, as well as to guide or fasten the electrical conductor structure 26, which extends from the second end section 16 toward the first end section 14.

[0047] As further evident from a combined review of FIGS. 3-6, nearly the entire display device 10 is arranged in the area of a window edge 6. The window edge 6 is provided with a window black print 9 sketched in FIG. 3. The electronic display 28 of the display device 10 is arranged in the transitional area to a transparent window area 19 spaced apart from the window edge 6. The first induction element 24 and second end section 16 of the carrier 22 are located completely in the area of the wiper black print 9. As further illustrated in FIG. 3, the transitional area between the window black print 9 and transparent window area 19 is provided with a bulge 44 toward the transparent window area 19. The first end section 14 of the display device 10 and the electronic display 28 come to lie in the area of this bulge 44 or formation.

[0048] As depicted in FIG. 2 in particular, the electronic display 28 is thus located above the instrument panel 5, so that the light that can be generated by the electronic display 28 or a corresponding visual warning signal can be readily and unimpededly perceived by the vehicle passengers.

[0049] While at least one exemplary embodiment has been presented in the foregoing detailed description, it should be appreciated that a vast number of variations exist. It should also be appreciated that the exemplary embodiment or exemplary embodiments are only examples, and are not intended to limit the scope, applicability, or configuration of the invention in any way. Rather, the foregoing detailed description will provide those skilled in the art with a convenient road map for implementing an exemplary embodiment as contemplated herein. It should be understood that various changes may be made in the function and arrangement of elements described in an exemplary embodiment without departing from the scope of the invention as set forth in the appended claims.
