Abstract

A monitor adapted for mounting in an automobile headrest is provided. A screen structure of the monitor is pivotable about an upper edge thereof, such that the monitor occupies little volume within the headrest. A viewing angle of the screen structure is independently adjustable by a viewer, such that the viewer can continuously select the optimum viewing angle with changing conditions inside the automobile. The screen structure automatically retracts into a housing when struck. Thus, the monitor poses little risk of injury to passengers.

Claims

1. A mobile video system comprising:

a headrest;

a screen structure having a front face, a rear face opposite the front face, and a first hinge portion;

a pivot-limiting portion; and

a housing coupled with the headrest and having a floor, a top surface, a bottom surface, and two side surfaces that cooperate to define a storage cavity sized and shaped to receive the screen structure, the housing having a second hinge portion that cooperates with the first hinge portion to pivotably secure the screen structure to the housing such that the front face of the screen structure is substantially flush with a surface of the headrest when the screen structure is in a storage configuration, the housing defining an opening that cooperates with the pivot-limiting portion to limit rotation of the screen structure relative to the housing to a location wherein when force is applied perpendicularly to the front face of the screen structure, the screen structure will rotate towards the storage configuration, and wherein a substantial portion of the rear face moves away from the floor of the housing when the screen structure is pivoted from the storage configuration.

2. The mobile video system of claim 1, wherein an angular orientation of the screen structure relative to the housing is adjustable without moving the headrest.

3. The mobile video system of claim 1, wherein the front face of the screen structure includes a viewing screen.

4. The mobile video system of claim 1, wherein the rear face of the screen structure comprises a channel configured to slidingly engage the pivot-limiting portion.

5. The mobile video system of claim 1, wherein the rear face of the screen structure is adjacent the floor of the housing when the screen structure is in the storage configuration.

6. The mobile video system of claim 1, wherein all of the rear face moves away from the floor of the housing when the screen structure is pivoted from the storage configuration.

7. The mobile video system of claim 1, wherein the screen structure is substantially the same size and shape as the storage cavity.

8. The mobile video system of claim 1, wherein the pivot-limiting portion limits rotation of the screen structure as the screen structure is moved away from the storage configuration.

9. The mobile video system of claim 1, wherein the first hinge portion is adjacent an edge of the screen structure.

10. The mobile video system of claim 1, wherein the pivot-limiting portion rotates within the opening as the screen structure pivots relative to the housing.

11. The mobile video system of claim 1, wherein the housing is removable from the headrest.

12. A mobile video system comprising:

a headrest configured to be mountable on a seatback so as to be movable toward and away from the seatback;

a screen structure having a front face, a rear face opposite the front face, and a first hinge portion;

a housing configured to couple with the headrest, the housing having a floor, a top wall, a bottom wall, and two side walls cooperating to define a storage cavity, the housing having a second hinge portion, the first hinge portion and the second hinge portion cooperating to pivotably secure the screen structure to the housing such that the front face of the screen structure is substantially flush with a surface of the headrest when the screen structure is stowed in the storage cavity in a stowed position, and wherein no portion of the rear face moves toward the floor of the housing when the screen structure is pivoted from the stowed position; and

a pivot-limiting portion and an opening which cooperate to limit pivotal movement of the screen structure relative to the housing to a location wherein when force is applied perpendicularly to the front face of the screen structure, the screen structure will rotate towards the storage configuration.

13. The mobile video system of claim 12, wherein the opening is defined by the housing.

14. The mobile video system of claim 12, wherein an angular orientation of the screen structure relative to the housing is adjustable without moving the headrest.

15. The mobile video system of claim 12, wherein the front face of the screen structure includes a viewing screen.

16. The mobile video system of claim 12, wherein the pivot-limiting portion comprises a bracket.

17. The mobile video system of claim 12, wherein the screen structure comprises a channel.

18. The mobile video system of claim 17, wherein at least a portion of the pivot-limiting portion is slidingly retained within the channel.

19. The mobile video system of claim 18, wherein the channel is at the rear face of the screen structure.

20. The mobile video system of claim 12, wherein at least a portion of the pivot-limiting portion is substantially L-shaped.

21. The mobile video system of claim 12, wherein a portion of the pivot-limiting portion is configured to extend through the opening.

22. The mobile video system of claim 21, wherein said portion of the pivot-limiting portion rotates within the opening as the screen structure is rotated relative to the housing.
