  • Patent number: 10421411
    Abstract: A monitor adapted for mounting in an automobile headrest is provided. A screen structure of the monitor is pivotable about an upper edge thereof, such that the monitor occupies little volume within the headrest. A viewing angle of the screen structure is independently adjustable by a viewer, such that the viewer can continuously select the optimum viewing angle with changing conditions inside the automobile. The screen structure automatically retracts into a housing when struck. Thus, the monitor poses little risk of injury to passengers. The housing of the monitor is attachable to the headrest with screws, which provides a very sturdy connection and reduces the chances of the housing becoming detached from the headrest during a vehicle collision. The hinged connection between the screen structure and the housing is preferably constructed of interconnected components made from sturdy materials, such as metals.

  • Patent number: 8429694
    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.

  • Patent number: 7894003
    Abstract: A vehicle roof mounted video display is disclosed. The display is rotatable 180° about a first axis, between a stored position within a housing and a second position in which the display lies flat against the vehicle roof. The display is also rotatable at least 60°, and preferably 90°, about a second axis that intersects and is substantially perpendicular to the first axis. Each axis includes self-tensioning hinges to hold the display in any position. The display self aligns as it reaches either of the first and second positions so that the display is substantially parallel to the roof. When the display is in the storage position, the display screen faces, and is safely enclosed by, the housing. The invention also includes a number of built-in features to provide passengers with a wide range of entertainment options.
