## Background
CROSS REFERENCE TO RELATED APPLICATION
This application claims the priority of U.S. Provisional Patent Application Ser. No. 63/006,974 filed on Apr. 8, 2020, the disclosure of which is incorporated herein by reference in its entirety.


TECHNICAL FIELD
Embodiments relate generally to panels for covering vehicle windows, and, more specifically, to a removable panel assembly configured to overlie at least a portion of a vehicle window, and related methods.
BACKGROUND
Vehicles, such as automobiles and vans, may be modified for specific uses in certain industries. For example, in the funeral industry, automobiles are permanently modified by coachbuilders into specialized hearses or funeral coaches. Among other things, hearses and funeral coaches traditionally have a distinctive shape and include distinctive external decorative elements. These vehicles often include a landau bar (an ornamental S-shaped metallic bar historically associated with the folding roof structure on a landau carriage) on each side of the rear portion of the vehicle. These vehicles typically have a recognizable appearance and are generally used only in connection with the funeral business.
Other vehicles used in the funeral industry include “first call” vehicles, which are used to pick up the remains of a recently deceased person and transport the remains to a funeral home for preparation. Full-size vans, minivans, and sport-utility vehicles are commonly used as first call vehicles. Many first call vehicles include internal modifications to facilitate transportation of deceased persons; however, external modifications, such as funeral-industry-specific ornamentation, may or may not be desirable in particular circumstances. For example, for some uses, it may be desirable for a first call vehicle to be readily recognizable as a funeral vehicle, such as by including landau bars.
The same first call vehicle may also be used in circumstances when it is not desirable for the vehicle to be easily recognizable as a funeral vehicle. For example, it may be desirable for the remains of a recently deceased person to be removed from a particular location discretely and without the presence of a recognizable funeral vehicle. Similarly, some funeral home operators may utilize a particular vehicle, such as a minivan, both in connection with their funeral business and for family transportation. Accordingly, the present disclosure contemplates that the ability to quickly and easily transform the external appearance of a vehicle between that of a standard vehicle and that of a recognizable funeral vehicle may be advantageous.
Some standard vehicles, such as certain minivans, include pivotable rear side windows. Removable landau panels (e.g., panels including landau bars) are available for some of these vehicles. Generally, these panels are installed or removed by sliding along the window while the window is in the open position, and shutting the window secures the panel in place. However, this type of panel is not usable on vehicles that do not include pivotable windows.
Accordingly, the present disclosure contemplates that there is a need for improved removable panels for vehicle windows, such as landau panels.

DETAILED DESCRIPTION
Referring to FIGS. 1 and 2, the illustrative vehicle 10 includes various windows, such as side windows 12, 14, 16 and a rear window 18. The illustrative panel assembly 100 is configured to be removably attached to the rear-most side window 16. A second panel assembly 100a, which is similar to the panel assembly 100 except that it is substantially a mirror image of the panel assembly 100, may be removably attached to the corresponding window on the opposite side of the vehicle 10.
An illustrative vehicle ornamentation kit may comprise one or more removable panel assemblies. For example, a vehicle ornamentation kit may include a panel assembly 100 for a window on the left side of a vehicle 10 and a panel assembly 100a for a window on the right side of the vehicle. The panel assemblies 100, 100a may be purchased and installed by an end user of the vehicle, or the panel assemblies 100, 100a may be installed by a dealer or distributor prior to sale of the vehicle 10 to the end user. Accordingly, a vehicle 10 may comprise one or more vehicle windows 12, 14, 16, 18 and one or more illustrative panel assemblies 100, 100a. 
Generally, the window 16 comprises a pane of automotive glass having an outward-facing surface 20, various edges (e.g., a top edge 22, a forward edge 24, a rear edge 26, and a bottom edge 28), and an inward-facing surface 30 (FIG. 8). The top edge 22 and the bottom edge 28 may be generally opposite each other and/or the forward edge 24 and the rear edge 26 may be generally opposite each other. Other illustrative embodiments may be configured for use on other windows 12, 14, 18.
The panel assembly 100 comprises a panel 102 that is sized and shaped to overlie at least a portion of the outward-facing surface 20 of the window 16. In some illustrative embodiments, the panel 102 may be generally the same size and shape as the window 16 so that the panel 102 substantially covers the entire outward-facing surface 20 of the window 16. In other illustrative embodiments, the panel 102 may overlie less than the entire window 16. For example, an alternative embodiment panel 102 may cover at least about 90% of the entire window 16.
The illustrative panel assembly 100 comprises a first retainer 104 and a second retainer 106 that are configured to secure the panel 102 in abutting relation to the window 16. As used herein, “in abutting relation” may describe a panel 102 that is partially or entirely in direct contact with all or a portion of the outward-facing surface 20 the window 16. As used herein, “in abutting relation” may also describe a panel 102 that is positioned substantially adjacent or alongside the outward-facing surface 20 of the window 16, with or without direct contact between the panel 102 and the window 16 and/or with or without a relatively small gap between some or all of the panel 102 and the window 16. In this illustrative embodiment, the first retainer 104 and the second retainer 106 are selectively connectable to the panel 102 and selectively detachable from the panel 102 as described in more detail below. The first retainer 104 and the second retainer 106 are readily engageable with and removable from the window 16.
The panel assembly 100 may include one or more ornamental elements disposed on an outward-facing surface 108 of the panel 102. For example, the illustrative panel assembly 100 comprises ornamental elements including a landau bar 110 and two landau buttons 112, 114 disposed on the outward-facing surface 108 of the panel 102. The landau bar 110 and/or the landau buttons 112, 114, may comprise a chrome surface. Alternatively, some assemblies 100 for funeral vehicles may include ornamental elements comprising wreaths, such as chrome wreaths. Other embodiments may include alternative ornamental elements, such as one or more indicia associated with a sports team, a trade, or a business, such as a nameplate, which may have a chrome surface.
