TECHNICAL FIELD
The invention relates to monitor mounting systems for land vehicle headrests and, more particularly, to monitor mounting systems constructed to be coupled to OEM headrest post guides and headrest posts.
BACKGROUND
Land vehicle entertainment systems have been popular for many years and, in recent years there has been a growing demand for monitor systems that can be mounted inside the back of a vehicle headrest. Conventional systems involve modifying the headrest so that a monitor, typically one with a DVD player built into the housing of the monitor, can be fitted into a recess formed in the back of the headrest. These systems require substantial changes to the headrest so that the monitor can be fitted into it, or they require complete substitution of the original headrest with one that contains a monitor in a back region of the substitute headrest. In conventional systems, the monitor is constructed to pivot so that it reveals a slot for insertion of a DVD. Examples of such conventional systems can be seen on the Internet at www.gualitymobilevideo.com/headrest-monitors.aspx.

DETAILED DESCRIPTION
As will be described below with reference to the drawings, the invention includes a monitor-mounting system that can be used to attach a monitor to a land vehicle headrest without having to change the component of that headrest that is designed to provide a body for resting the passenger's or driver's head against. As used herein, a vehicle headrest includes a body at a top region of the headrest, with dual posts that extend downwardly from the body through post guides that are positioned in a vehicle seat. These components of a headrest are not part of the invention, but are shown, for example, in FIGS. 2-3 and 7-8.
Preliminary to discussing further details of the invention, it should be understood that the monitor-mounting system can be used with any suitable monitor, such as a suitable LCD monitor, with integrated DVD player. Such LCD monitors, with suitable wiring for connecting to a vehicle power system can be obtained from Rosen Entertainment Systems of Corona, Calif. A version of the invention may be obtained from Rosen Entertainment Systems and it is marketed under the trademark AV7700.
Referring to FIGS. 1-6, an embodiment of the invention is shown after the bushing subsystem 12 has been coupled around the outside of the post guides B of a conventional vehicle headrest 1. The vehicle headrest 1 is constructed with dual posts B and dual post guides C like the single post B and guide C shown in FIG. 1. The bushing system is constructed with dual bushings 13, or bushing halves 13, like those shown and described in connection with FIG. 5 below, with each being constructed to couple to a corresponding one of the dual post guides C.
FIGS. 1-6 show details of the monitor-mounting system 10, which includes a bushing subsystem 12 as the two bushing halves 13 that are shown in an exploded view away from a fragmentary section of a conventional headrest post B that is positioned through a conventional post guide C (as shown and described with respect to in FIG. 1). The bushing subsystem 12 is constructed to be coupled to the headrest 1. In this embodiment, that coupling occurs by bringing the two bushing halves 12 together around each post guide C, one of which is depicted in FIG. 5 and, and under the cap of the post guide C which is shown as the topmost region of that post guide C (e.g., see FIG. 2).
Referring again to FIG. 1, a monitor-mounting plate 16, 20 (shown exploded from the conventional headrest post B and post guide C) is constructed to be coupled to the bushing subsystem 12, and it includes dual forks 16 and a monitor-mounting region 20 (the region shown at the far rights that includes a flat, horizontal section 16 and an upright section 20 with holes formed therein for receiving suitable fasteners that attach a monitor (undepicted) to that upright region 20. As shown in FIGS. 1, 2, 3 and 6, the monitor-mounting plate 16, 20 extends outwardly of the headrest 1 and is constructed for fixedly receiving a monitor 11 via the monitor-mounting region 20.
A locking piece 15 (also referred to as a locking metal piece) is also shown in FIGS. 1 and 4, and it is used to lock the monitor-mounting plate 16, 20 in position (e.g., via sliding lock 15 into channels 18) after the forks have been moved into the channels 14 formed in the bushing halves 13. By placing the monitor-mounting plate 16, 20 in those channels 14, the bushing halves 13 are held together. By placing the shown locking metal piece 15 through the channel 14 of the bushing halves 13 as shown in FIG. 4, and placing the locking metal piece 15 also through channels 18 of the monitor-mounting plate 16, 20, the monitor-mounting plate 16, 20 is secured and capable of holding a monitor 11 in a desired position for viewing by vehicle back seat passengers (undepicted).
Concerning materials for the inventions, any suitable material may be used, including metal and composite materials.
FIG. 2 shows illustrations of the monitor-mounting system of the invention after being coupled to a conventional vehicle headrest 1 and after the monitor-mounting region 20 of the monitor-mounting plate 16, 20 has been fastened to a monitor 11.
FIGS. 3 and 5 shows additional illustrations of a monitor 11 after it has been attached to the invention, but without showing the conventional headrest posts and/or post guides.
FIG. 7 is directed to two more embodiments of the invention, including dual bushing halves 113 with interior surfaces that have been formed to match the outer surface of a conventional headrest post guide (e.g., C in FIG. 1). Those bushing halves 113 have bodies that are formed with an oval shape. The oval-shaped embodiment could alternately be employed as another embodiment that is square shaped. In each of the embodiments described with respect to FIG. 7, the locking metal piece 115 is shown extending towards the corresponding channels (e.g., like channel 14 in FIG. 1) of the bushing halves 113 to illustrate that they slide into place.
In some embodiments of the invention that are also designed for use with the conventional headrest 1 described above, only that this embodiment includes a bushing subsystem that is constructed with dual bushings, or bushing halves (e.g., like 13 in FIG. 1), each being constructed to couple to a corresponding one of the dual posts B. Similar to the embodiment of FIG. 1, this embodiment also includes a bushing subsystem and a monitor-mounting plate. That plate includes a U-shaped end that can be moved into the channels (e.g., like channel 14 in FIG. 1) of the bushing halves 13. A locking piece (e.g., like 15 in FIG. 1) can be slid into a corresponding channel (e.g., like 18 in FIG. 1) after the monitor-mounting plate is slid into position through the channels (e.g., like 14 in FIG. 1) of the bushing halves. In some embodiments, the bushing halves may have any desired size, such as 10 mm, 11 mm, 12 mm, 12.7 mm, and 14 mm. It is intended that the monitor-mounting plate (e.g., 16, 20) remain the same size for all versions of this embodiment. This embodiment attaches to the conventional headrest post B, as opposed to the post guide C, as the other embodiments discussed above do.
Although the present invention has been shown and described with reference to the foregoing operational principles and preferred embodiments, it will be apparent to those skilled in the art that various changes in form and detail may be made without departing from the spirit and scope of the invention. The present invention is intended to embrace all such alternatives, modifications and variances that fall within the scope of the appended claims.
