DETAILED DESCRIPTION

(8) Reference is now made to FIG. 1a illustrating an electronics systems cluster C including a plurality of brackets B.sub.1-B.sub.4 for holding separate electronic devices. The double-ended action arrows indicate clearance required between the brackets B.sub.1-B.sub.4 and the cover buttons CB to robotically place individual brackets on the windshield W. The line L indicates the outline of the cover for the electronics systems cluster C which is the effective footprint of such an electronics systems cluster with separate brackets in the absence of any interlocking features to secure those brackets directly together.

(9) FIG. 1b is a schematic illustration of the new and improved electronics systems cluster 10 that is the subject matter of this document. That electronics systems cluster 10 includes a plurality of brackets 12.sub.1-12.sub.n. A plurality of electronic devices 14.sub.1-14.sub.n are received and held in the plurality of brackets 12.sub.1-12.sub.n. In the illustrated embodiment, one electronic device 14.sub.1-14.sub.n is held in each of the brackets 12.sub.1-12.sub.n.

(10) As illustrated in FIG. 1b, the electronics systems cluster 10 also includes an interlocking feature, generally designated by reference numeral 16, for securing the plurality of brackets 12.sub.1-12.sub.n directly together. By securing the separate or independent brackets 12.sub.1-12.sub.n together, it is no longer necessary to provide space between the brackets for robotic placement as illustrated in FIG. 1a. Accordingly, the plurality of brackets 12.sub.1-12.sub.n holding the plurality of electronic devices 14.sub.1-14.sub.n consume a smaller space and have a smaller footprint. This is visually indicated by comparing the outline of the cover 18 for the electronics systems cluster 10 to the phantom line 20 which represents the expanse of the cover of the electronics systems cluster C illustrated in FIG. 1a wherein the plurality of brackets B.sub.1-B.sub.4 do not include any interlocking feature.

(11) Advantageously, by reducing the footprint of the electronics system cluster 10 and providing a more compact design, forward vision obstruction by the electronics systems cluster is minimized and the sightlines of the driver are enhanced for easier operation of the motor vehicle.

(12) As illustrated in FIG. 1b, the interlocking feature 16 may include cooperating male connectors 22 and female connectors 24. The male connectors 22 and female connectors 24 may be molded with and formed as an integral part of the brackets 12.sub.1-12.sub.n.

(13) As illustrated in FIG. 2a, the cooperating male connector 22 received in the female connector 24 may function as a four-way locator (note action arrows A). In contrast, as illustrated in FIG. 2b, the cooperating male connector 22 received in the female connector 24 may comprise a two-way locator (note action arrow D).

(14) As illustrated in FIG. 3, the interlocking feature 16 may comprise a plurality of cooperating dovetail connectors 26. Those cooperating plurality of dovetail connectors 26 may be provided along edges of the brackets 12.sub.1-12.sub.n as shown.

(15) As illustrated in FIG. 3, the first bracket 12.sub.1 receives and holds an image processing module A 30, the second bracket 12.sub.2 receives and holds a rain light sensor 32, the third bracket 12.sub.3 receives and holds an electronic windshield anti-fogging system 34 and the fourth bracket 12.sub.n receives and holds a USB port 36 for charging an electronic device or providing a data pathway between an electronic device and an onboard motor vehicle system through the controller area network (CAN) of the motor vehicle. In the illustrated embodiment, the interlocking feature 16 or, more specifically, dovetail connectors 26, secure the second bracket 12.sub.2 to the first bracket 12.sub.1, the third bracket 12.sub.3 to the second bracket and the fourth bracket 12.sub.n to the first bracket. An adhesive 38 (on the side hidden from view) secures the first bracket 12.sub.1, the second bracket 12.sub.2, the third bracket 12.sub.3 and the fourth bracket 12.sub.n to the windshield 40 of the motor vehicle. The cover 18 conceals the brackets 12.sub.1-12.sub.n and the electronic devices 14.sub.1-14.sub.n held therein from view so as to provide an aesthetically pleasing package.

(16) The cover 18 is secured in place on the cover buttons or clip points 42. In the embodiment illustrated in FIG. 3, the cover buttons or clip points 42 are provided on separate cover brackets 44.sub.1, 44.sub.2. In the illustrated embodiment, the cover bracket 44.sub.1 is connected by interlocking features 16 to the third bracket 12.sub.3 while cover bracket 44.sub.2 is connected by the interlocking feature 16 to the fourth bracket 12.sub.n. Here it should be appreciated that in other embodiments, the cover buttons or clip points 42 may be provided on one or more of the brackets 12.sub.1-12.sub.n.

(17) In addition to the features described above, the brackets 12.sub.1-12.sub.n may include wire routing features 46, such as posts, clips or the like, and a tethering hook 48. The wire routing features 46 receive and hold wiring to prevent rattling while the tethering hook 48 functions as an anchor point for a tether connected to a rearview mirror. That tether (not shown) will prevent a rearview mirror from flying freely across the passenger compartment of the motor vehicle in the event of an accident of sufficient force to dislodge the rearview mirror from the windshield.

(18) Heater terminals 50 may also be carried on one or more of the brackets 12.sub.1-12.sub.n or cover brackets 44.sub.1-44.sub.2. Such heater terminals 50 are provided for a local windshield heating grid used to maintain a clear windshield in front of the image processing module A 30.

(19) Consistent with the above description, a method is provided for reducing a footprint of an electronics system cluster 10 on top of a windshield 40 of a motor vehicle. That method comprises the steps of: (a) locating a plurality of electronic devices 14.sub.1-14.sub.n in a plurality of brackets 12.sub.1-12.sub.n, (b) interlocking, by interlocking feature 16, the plurality of brackets together and (c) adhering, by adhesive 38 the plurality of brackets to the windshield 40.

(20) In one or more of the many possible embodiments, the method includes the step of interlocking, by the interlocking feature 16, the first bracket 121, carrying an image processing module A 30 with a second bracket 12.sub.2 carrying a rain light sensor 32. Further, the method may include the step of interlocking, by the interlocking feature 16, the third bracket 12.sub.3, carrying an electronic windshield anti-fogging system 34, to the second bracket 12.sub.2. Further, the method may include the step of interlocking, by the interlocking feature 16, the fourth bracket 12.sub.n, carrying a USB port 36, to the first bracket 12.sub.1.

(21) In addition, the method may include providing at least one wire routing feature 46 on at least one of the brackets 12.sub.1-12.sub.n. Further, the method may include allowing, by the interlocking feature 16, freedom of movement perpendicular to a tangent plane of the windshield 40. In other words, the interlocking feature 16 allows for one bracket to be staggered in position with respect to an adjacent bracket in order to accommodate windshield curvature and allow for proper windshield mounting using a simple and inexpensive adhesive. This also allows for windshield variability so that the quick curing adhesive may be used to fix the individual brackets 12.sub.1-12.sub.n to a number of different windshields of different shape across a wide model range. This reduces the number of parts required by the motor vehicle manufacturer and provides substantial savings in production costs.

(22) The foregoing has been presented for purposes of illustration and description. It is not intended to be exhaustive or to limit the embodiments to the precise form disclosed. Obvious modifications and variations are possible in light of the above teachings. For example, as illustrated above, the interlocking feature 16 comprises cooperating male 22 and female 24 connectors such as the four-way locator schematically illustrated in FIG. 2a, the two-way locator schematically illustrated in FIG. 2b, and the cooperating dovetail connectors 26 schematically illustrated in FIG. 3. It should be appreciated that the interlocking feature 16 may comprise a variety of different shapes and sizes even in the same electronics systems cluster 10. This would allow the plurality of brackets 12.sub.1-12.sub.n to be pieced together in the manner of a puzzle thereby ensuring that the brackets are all interconnected in the proper configuration. All such modifications and variations are within the scope of the appended claims when interpreted in accordance with the breadth to which they are fairly, legally and equitably entitled.
