Abstract

An automatic tilt mechanism for attaching a monitor to a movable structure, comprising: a hinge having a first leg means for attachment to a monitor, a second leg means for attachment to the movable structure and a pivot joining the first and second leg means so that they can be moved with respect to each other after attachment; a transfer means adapted to move in proportion to movement of the movable structure; and a connecting means for transmitting movement of the transfer means to the hinge so that the first leg means moves proportionally to movement of the movable structure. The invention may further include a reclinable seat back of a seat in a passenger vehicle as the movable structure. The invention may still further include a fixed length sheathed cable as the connecting means. The invention may also provide an automatic tilt mechanism that is driven by motion of the seat back.

Claims

1. An automatic tilt mechanism attaching a monitor to a reclinable seat back having a predetermined tilt angle range, the monitor being located in rear of the seat back, comprising:

a hinge having a first leg means attached to the monitor, a second leg means attached to the reclinable seat back and a pivot joining the first and second leg means so that they can be moved with respect to each other after attachment;

a transfer means adapted to move in proportion to movement of the reclinable seat back; and

a connecting means for transmitting movement of the transfer means to the hinge so that the first leg means moves proportionally to the movement of the reclinable seat back such that the monitor will maintain a constant viewing angle with respect to a viewer through the predetermined tilt angle range.

2. The automatic tilt mechanism of claim 1, wherein said reclinable seat back comprises a portion of a seat in a passenger vehicle.

3. The automatic tilt mechanism of claim 2, wherein said transfer means comprises a first arm fixedly attached to a seat part of said seat, and a second arm attached to said seat back, said first and second arms being attached pivotally so that the second arm moves with the seat back relative to the first arm.

4. The automatic tilt mechanism of claim 1, or 3, wherein said connecting means is a cable assembly means.

5. The automatic tilt mechanism of claim 4, wherein said cable assembly means is a fixed length cable in a sheath.

6. The automatic tilt mechanism of claim 1, or 3, wherein said mechanism is driven by motion of the seat back.

7. The automatic tilt mechanism of claim 3, wherein the hinge further comprises a return spring attached to corresponding ends of said first and second leg means located opposite the pivot.

8. The automatic tilt mechanism of claim 3, wherein a first end of the connecting means is attached to the monitor and a second end of said connecting means is attached to said second arm of the transfer means.

9. A system for mounting a monitor in a reclinable seat back of a seat, comprising:

a monitor tilt means rotatably attached to the monitor having a first leg means attached to the monitor and a second leg means fixedly attached to the reclinable seat back,

a seat back transfer means located remote from the monitor and the monitor tilt means, having a first arm fixedly attached to a portion of the seat and a second arm attached to the seat back, said first and second arms being pivotally attached so that the second arm moves with the seat back relative to the first arm, and

means connecting the monitor to said second arm of the transfer means so that movement of the seat back causes proportional movement of the seat back transfer means, the seat back transfer means adapted to cause proportional movement of the monitor to maintain a constant viewing angle of the monitor for a viewer.

10. The system of claim 9, wherein the monitor tilt means has a tilt angle and the transfer means has a corresponding tilt angle substantially equal to said monitor tilt means tilt angle.

11. The system of claim 9, wherein the connecting means is a fixed length cable assembly.
