Abstract

An armrest that has a plurality of telescopic trays that collapse to allow a viewing device to be retracted from a stowing compartment within the armrest. The telescopic trays can then be rolled back while the viewing device is displayed, allowing the passenger to utilize both the monitor and the trays. The viewing device is connected to a slide plate that slides along a track that is mounted within the stowing compartment. The plate and track allow the monitor to be retracted from the compartment. The viewing device is also attached to a pair of joints, such that the device can be rotated about the x, y and z axis, to allow the passenger to display and move the monitor into the most comfortable position.

Claims

1. A display unit that exposes a viewing device stored in a stowing compartment of an armrest having an x, y and z axis, comprising:

sliding means operatively connected to the viewing device for positioning the viewing device along the y-axis of the armrest, such that the viewing device can be stored or retracted from the stowing compartment;

first rotational means operatively connected to the viewing device for rotating the viewing device about the y-axis of the armrest; and

second rotational means operatively connected to the viewing device for rotating the viewing device in a plane parallel to the y-axis of the armrest.

2. The display unit as recited in claim 1, wherein said sliding means comprises;

a track attached to the armrest within the stowing compartment, said track having a first groove extending along the y-axis of said track; and

a first slide plate operatively connected to the viewing device, said first slide plate being adapted to slide along said first groove of said track, whereby said viewing device can be positioned along the y-axis of the armrest.

3. The display unit as recited in claim 2, further comprising first stop means for securing said first slide plate at a first predetermined position on said track.

4. The display unit as recited in claim 2, further comprising a second slide plate operatively connected to the viewing device, said second slide plate being adapted to slide along a second groove in said first slide plate, whereby said viewing device can be positioned along the y-axis of the armrest.

5. The display unit as recited in claim 4, further comprising second stop means for securing said second slide plate at a second predetermined position on said first slide plate.

6. The display unit as recited in claim 1, wherein said first rotational means comprises;

a first housing operatively connected to said sliding means, said first housing having a first bore; and

a first bearing operatively connected to the viewing device and supported by said first housing, said first bearing being adapted to move within said first bore such that the viewing device can be rotated about the y-axis.

7. The display unit as recited in claim 6, wherein said second rotational means comprises;

a second housing operatively connected to said sliding means, said second housing having a second bore; and

a second bearing attached to the viewing device and supported by said second housing, said second bearing being adapted to move within said second bore such that the viewing device can be rotated in a plane parallel to the y-axis.

8. A display unit that stores a viewing device in a stowing compartment having an x, y and z axis, comprising:

a track attached to the armrest within the stowing compartment, said track having a first groove extending along the y-axis of said track;

a first slide plate adapted to slide along said first groove of said track, said first slide plate having a second groove along the y-axis of said first slide plate;

a second slide plate adapted to slide along said second groove in said first slide plate;

a first housing connected to said second slide plate, said first housing having a first bore;

a first bearing operatively connected to the viewing device and supported by said first housing, said first bearing being adapted to move within said first bore such that the viewing device can be rotated about the y-axis;

a second housing operatively connected to said first housing, said second housing having a second bore; and

a second bearing attached to the viewing device and supported by said second housing, said second bearing being adapted to move within said second bore such that the viewing device can be rotated in a plane parallel to the y-axis;

whereby said movement of said first and second slide plates relative to said first and second grooves, respectively, provides for positioning of the viewing device along the y-axis of the armrest to retract or restore the viewing device from the stowing compartment, and said rotational movement of said first and second bearings relative to said first and second housings, respectively, provides for rotational positioning of the viewing device about the x, y and z axis to further display the viewing device.

9. The display device as recited in claim 8, wherein said second slide plate is attached to said first slide plate by a screw that threads into a nut, said nut is pressed into said first slide plate such that the viewing device can be detached from said first slide plate by applying a predetermined force to the viewing device.

10. The display device as recited in claim 8, further comprising an O-ring operatively connected to said first bearing and said first housing, and an O-ring operatively connected to said second bearing and said second housing, said O-rings apply controlled frictional forces to said bearings such that said bearings and the viewing device do not rotate until a predetermined moment is applied to the viewing device.

11. The display device as recited in claim 8, wherein said first and said second bearings have bores extending through the longitudinal axis therein, said bores providing access for an electrical cable to run from an external source to the viewing device.
