Abstract

A mobile video system includes a first video source, a second video source, a first video monitor, a second video monitor, an audio signal receiver, and a wireless transmitter. One of the first video source and the second video source generates a first audiovisual signal. One of the first video monitor and the second video monitor receives a video portion of at least one of the first audiovisual signal and the second audiovisual signal. The wireless transmitter transmits an audio portion of one of the first audiovisual signal or the second audiovisual signal to the audio signal receiver. A video portion of the first audiovisual signal or the second audiovisual signal is displayed on the first video monitor, on the second video monitor, or on both the first video monitor and the second video monitor.

Claims (13)

1. A mobile video system comprising:

a motorized land vehicle comprising a passenger compartment, a seat having a headrest, the seat positioned in the passenger compartment;

a first video source that generates a first audiovisual signal;

a second video source that generates a second audiovisual signal;

a first video monitor configured to receive a video portion of at least one of the first audiovisual signal and the second audiovisual signal, the first video monitor comprising:

a screen structure defining a first hinge portion and including a viewing screen;

a housing sized and shaped to be substantially positioned within the headrest, the housing at least partially defining a floor, a first wall and a second wall which cooperate to at least partially form a storage cavity adapted to receive the screen structure, the floor having an aperture formed therein, the housing further comprising a second hinge portion adapted to cooperate with the first hinge portion of the screen structure, wherein the first hinge portion and the second hinge portion cooperate to permit rotation about an axis but prevent radial movement with respect to the axis; and

a removable fastening member configured to be advanced through the aperture of the housing and to be coupled with the headrest to secure the video monitor thereto;

wherein the first and second hinge portions cooperate to pivotably secure the screen structure to the housing such that when the screen structure is pivoted outward from the housing to a non-viewing angle, access is provided to the second fastener, wherein the second fastener is hidden from view during normal usage of the video monitor; and

a second video monitor mounted in the passenger compartment, the second video monitor configured to receive a video portion of at least one of the first audiovisual signal and the second audiovisual signal;

whereby a video portion of either of the first audiovisual signal or the second audiovisual signal can be displayed on the first video monitor, on the second video monitor, or on both the first video monitor and the second video monitor.

2. The mobile video system of claim 1 , further comprising a radio that includes a loudspeaker and that is installed in the vehicle.
