Patent ID: 7758117

Claim:
A mobile entertainment system comprising: a headrest configured to be installed in a vehicle; a housing mounted to the headrest, the housing defining a first hinge portion and a first lock portion, the first lock portion having a first surface; and a screen assembly including a viewing screen, the screen assembly defining a second hinge portion that cooperates with the first hinge portion to pivotally couple the screen assembly with the housing, the screen assembly further defining a second lock portion that comprises a manual interface, the second lock portion cooperating with the first lock portion to selectively secure the screen assembly in substantially fixed relation to the housing, the second lock portion having a second surface, wherein the first surface interferes with the second surface to prevent rotation of the screen assembly relative to the housing when the screen assembly is in a stowed position, and wherein the manual interface is configured to move in a direction substantially parallel to a plane defined by the viewing screen in order to overcome interference of the first and second surfaces, thereby permitting the screen assembly to be rotated to a deployed position.
