(10) The embodiments, examples and alternatives of the preceding paragraphs, the claims, or the following description and drawings, including any of their various aspects or respective individual features, may be taken independently or in any combination. Features described in connection with one embodiment are applicable to all embodiments, unless such features are incompatible.

DETAILED DESCRIPTION

(11) FIG. 1A schematically illustrates a vehicle cab 10 in cross-section. The vehicle cab 10 includes a front 12 having a windshield 14 and first and second sides 16, 18, which correspond to driver and passenger sides of the vehicle cab 10.

(12) Some vehicle cab manufacturers provide preexisting mounting points 20, which may be used for attaching accessory components, such as a sun visor. The sheet metal or fiberglass at the mounting points 20 may have preexisting reinforcements. Reinforcements can be added if not provided at mounting locations. In one embodiment of this disclosure, the camera mirror vehicle mounting system takes advantage of these preexisting mounting points 20 such that drilling and creation of potential water ingress locations does not occur. Mounting points 20 may also be provided on the roof of the vehicle cab 10 in addition to or instead of at the front of the vehicle cab 10.

(13) The camera mirror vehicle mounting system includes a first bracket portion 22 having multiple discrete spaced apart plates 26 that are secured to the preexisting mounting points 20 by fasteners 24. The fasteners 24 extend through apertures 28 in the plates 26 (FIG. 1B). In one example shown in FIG. 1A, the first bracket portion 22 is provided by a single bar having a curvature generally corresponding to the contour of the front 12. The bar may terminate in spaced apart end plates 30 that support camera brackets 32, as shown in FIGS. 4 and 5. In one example, the bar is a hollow metal tube.

(14) First and second camera assemblies 34, 36 are secured to their respective camera bracket 32. Slotted holes 38 (FIG. 6) may be provided in the camera brackets 32 to permit a coarse adjustment of the camera assemblies during a calibration procedure by loosening and then tightening fasteners 40 during adjustment. The camera assemblies 34, 36 are secured to the camera brackets 32 by fasteners (not shown), which enables easy replacement of the camera assemblies if they become damaged.

(15) There are no preexisting mounting points beneath the end plates 30 in some manufacturer's vehicle cabs. In such instances when it is undesirable to create mounting points for the end plates, e.g., by drilling, an interference fit may be used between the end plates 30 and the vehicle cab 10. A compressible material 42 may be provided between the end plates 30 and the exterior of the vehicle cab 10. In this manner, the vehicle cab 10 may be positioned between the opposing compressible materials 42, creating an interference fit, which securely maintains the position of the camera assemblies with respect to the vehicle cab 10 to avoid undesired vibration. In one example, the compressible material 42 has an adhesive on each side, which secures to the vehicle 10 and the end plate 30, which further stabilizes the end plate position.

(16) At least one plate 26 provides a first attachment feature, and at least one end plate 30 provides a second attachment feature. Neither of the first and second attachment features, which are remote from one another for overall system stability, rely upon specially drilled holes for the mounting of the system. Only preexisting holes from the OEM are used to secure the system to the vehicle. Using preexisting holes provided from the OEM manufacture of the vehicle enables the system to be reliably and repeatably mounted to vehicles in an aftermarket setting.

(17) The vehicle manufacturer or aftermarket suppliers may provide second bracket portions 44 (FIGS. 2-3) and a sun visor 46 as part of an aftermarket kit for certain vehicle manufacturer configurations. The first bracket portion 22 and its various mounting locations may be configured to not only take advantage of the vehicle cab 10 preexisting mounting points 20 (i.e., provided by the OEM during manufacturing) but also the available bracketry and sun visor contours available in the after-market or by the original equipment manufacturer. In the example, the second bracket portions 44 are arranged in an overlapping relationship with the plates 26 and are secured using the fasteners 24. The sun visor 46 is secured to the second bracket portion 44. Although the first and second bracket portions 22, 44 are shown as separate, discrete elements from one another, the bracket portions may be integrated, if desired.

(18) A wire bundle 48 is interconnected between the first and second camera assemblies 34, 36. This wire bundle 48 may be secured to the exterior of the first bracket portion 22 by, for example, zip ties. Alternatively, the wire bundle 48 may be arranged within the first bracket portion 22 if it is provided as a hollow bar. The wire bundle 48 may terminate in a single, common pig tail, which is then passed through a hole 50 in the vehicle cab 10. The installer may have to drill a hole into the vehicle for the wiring, although such a hole need not be precisely located and is easily sealed with a rubber grommet or the like. As shown in FIG. 1, this wire bundle 48 is joined to a wire harness 148 connected to first and second displays 52, 54, which respectively provide Class II and Class IV views, respectively, to the driver. One or more displays may be provided for Class VI and/or Class V views, if desired. The camera(s) used for Class V and/or Class V views may also be supported by the first bracket portion 22.

(19) In another example shown in FIG. 1C, a pair of discrete bars provide a pair or first bracket portions 22a, 22b, one for each side of the vehicle. Each of the first bracket portions 22a, 22b include a pair of the plates 26 for securing the bars to the vehicle. Separate bars provides improved adjustability and enables one installer to more easily mount the first bracket portions 22a, 22b to the vehicle, one at a time. The end plates 30 can be secured to the vehicle 10, as described above. If a common wiring bundle 48 is used for both of the first and second camera assemblies 34, 36, then a wire connector 49 can be used to simplify assembly of the system during aftermarket assembly.

(20) It should also be understood that although a particular component arrangement is disclosed in the illustrated embodiment, other arrangements will benefit herefrom. Although particular step sequences are shown, described, and claimed, it should be understood that steps may be performed in any order, separated or combined unless otherwise indicated and will still benefit from the present invention.

(21) Although the different examples have specific components shown in the illustrations, embodiments of this invention are not limited to those particular combinations. It is possible to use some of the components or features from one of the examples in combination with features or components from another one of the examples.

(22) Although an example embodiment has been disclosed, a worker of ordinary skill in this art would recognize that certain modifications would come within the scope of the claims. For that reason, the following claims should be studied to determine their true scope and content.
