BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a television seat.

[0002]

2. Description of the Related Art In a room such as a railway car, a bus, an aircraft, or a theater, a seat cushion for supporting a seated part of a seated person, a seat back which can be tilted in the front-rear direction with respect to the seat cushion, It is known in the art to arrange a television seat with a supported television. The television is to be viewed by a seated occupant behind a seat back that supports the television.

[0003] However, when a seat occupant in front of the viewer tilts his or her seat back when watching the television, the television also tilts together. The angle formed with the television screen changes greatly, and the visibility of the television decreases. In particular, in a liquid crystal television, when the angle between the viewer's line of sight and the television screen is close to a right angle, the image looks sharp, but if this angle changes even slightly, it becomes extremely difficult to see.

[0004] In order to prevent such a problem, the upper side of the television is rotatably supported with respect to the seat back, and when the seat back in front of the viewer is tilted, the viewer behind the viewer is tilted accordingly. However, there is also known a TV-equipped seat configured to change the inclination of the television and adjust the angle of the television to a position where the television can be easily viewed. However, it is very troublesome to adjust the angle of the television every time the seat back is tilted, so that the television cannot be enjoyed because the user falls back.
