Abstract

An improved seat includes a seat bottom and adjustable seat back. The seat back is movable between an upright position and a reclined position. The improvement in the seat includes an adjustable display screen assembly mounted on a back side of the seat back. The display screen assembly defines on one side thereof a display screen surface for being viewed by a viewer located behind the seat. A pivot bolt is associated with the display screen assembly for allowing pivoting movement of the display screen assembly relative to the seat back. A control cable assembly automatically controls the pivoting movement of the display screen assembly in coordination with the movement of the seat back. The control cable assembly operates to maintain the display screen assembly at a predetermined viewing angle relative to the viewer as the seat back moves between the upright and reclined positions.

Claims

1. In combination with a seat having a seat bottom and adjustable seat back, the seat back being movable between an upright position and a reclined position, the improvement comprising:

(a) an adjustable display screen assembly mounted on a back side of the seat back, and defining on one side thereof a display screen surface for being viewed by a viewer located behind the seat;

(b) pivot means interconnecting said display screen assembly and said seat back for allowing pivoting movement of said display screen assembly relative to the seat back; and

(c) control means responsive to movement of the seat back for controlling the pivoting movement of said display screen assembly in coordination with the movement of said seat back to thereby maintain the display screen assembly at a predetermined viewing angle relative to the viewer as the seat back moves between the upright and reclined positions, said control means comprising a control cable assembly extending downwardly from the display screen assembly to the seat bottom, said control cable assembly including a cable having first and second ends, the first end being connected to the display screen assembly and the second end being non-pivotally connected to the seat bottom.

2. An improved seat according to claim 1, wherein said control cable assembly further includes a slip sheath having first and second openings through which the respective ends of the cable extend, the cable moving within said sheath in response to the movement of said seat back.

3. An improved seat according to claim 1, wherein a back side of the seat back defines a recess therein for receiving the display screen assembly.

4. An improved seat according to claim 3, wherein said display screen assembly includes a mounting plate positioned in the recess of the seat back for mounting said display screen assembly to the seat back.

5. An improved seat according to claim 4, wherein said mounting plate includes first and second spaced-apart flanges each defining an opening therein for receiving said pivot means.

6. An improved seat according to claim 5, wherein said pivot means comprises at least one pivot bolt extending through each of the first and second flange openings and connecting to the seat back for allowing pivoting movement of the display screen assembly in coordination with the movement of the seat back.

7. An improved seat according to claim 6, wherein said control means includes a spring attached to an upper end of the mounting plate, said spring extending downwardly below the upper end of the mounting plate to a connecting point located in an open area adjacent to the recess, said spring cooperating with said at least one pivot bolt to urge a lower end of said mounting plate outwardly away from the seat back.

8. In combination with a seat having a seat bottom and adjustable seat back, the seat back being movable between an upright position and a reclined position, the improvement comprising:

(a) an adjustable display screen assembly mounted on a back side of the seat back, and defining on one side thereof a display screen surface for being viewed by a viewer located behind the seat;

(b) pivot means associated with said display screen assembly for allowing pivoting movement of said display screen assembly relative to the seat back;

(c) a control cable assembly extending downwardly from the display screen assembly to the seat bottom, and including a cable having first and second ends, the first end being connected to the display screen assembly and the second end being non-pivotally connected to the seat bottom; and

(d) said control cable assembly further including a slip sheath having first and second openings through which the respective ends of the cable extend, the cable moving within said sheath in response to the movement of said seat back, whereby the display screen assembly is maintained at a predetermined viewing angle relative to the viewer as the seat back moves between the upright and reclined positions.

9. An improved seat according to claim 8, wherein a back side of the seat back defines a recess therein for receiving the display screen assembly.

10. An improved seat according to claim 9, wherein said display screen assembly includes a mounting plate positioned in the recess of the seat back for mounting said display screen assembly to the seat back.

11. An improved seat according to claim 10, wherein said mounting plate includes first and second spaced-apart flanges each defining an opening therein for receiving said pivot means.

12. An improved seat according to claim 11, wherein said pivot means comprises at least one pivot bolt extending through each of the first and second flange openings and connecting to the seat back for allowing pivoting movement of the display screen assembly in coordination with the movement of the seat back.

13. An improved seat according to claim 12, wherein said control means includes a spring attached to an upper end of the mounting plate, said spring extending downwardly below the upper end of the mounting plate to a connecting point located in an open area adjacent to the recess, said spring cooperating with said at least one pivot bolt to urge a lower end of said mounting plate outwardly away from the seat back.

14. In combination with a seat having a stationary seat bottom and adjustable seat back, the seat back being movable between an upright position and a reclined position, the improvement comprising:

(a) an adjustable display screen assembly mounted on a back side of the seat back, and defining on one side thereof a display screen surface for being viewed by a viewer located behind the seat;

(b) pivot means interconnecting said display screen assembly and said seat back for allowing pivoting movement of said display screen assembly relative to the seat back; and

(c) control means responsive to movement of the seat back for controlling the pivoting movement of said display screen assembly in coordination with the movement of said seat back to thereby maintain the display screen assembly at a predetermined viewing angle relative to the viewer as the seat back moves between the upright and reclined positions, said control means comprising a control cable assembly extending downwardly from the display screen assembly to the seat bottom, said control cable assembly including a cable having first and second ends, the first end being connected to the display screen assembly and the second end being fixed to the stationary seat bottom for transmitting relative movement between the stationary seat bottom and the moveable seat back to the display screen assembly.
