Abstract

A stowable video display system is provided for mounting in a passenger compartment of a vehicle, the display unit including a base, a display screen, a pivotal coupling structure, a first position-fixing member and a second position-fixing member. The display screen is pivotally coupled to the base, and is pivotal between a stowed position in which the screen is not visible to a viewer, and a deployed position in which the screen is visible to a viewer. The deployed position is selected from positions within a continuous range of possible deployed positions. The pivotal coupling pivotally couples the screen to the base, and includes a dampening mechanism adapted to dampen the deployment of the screen. The first position-fixing member is on the base. The second position-fixing member is on the pivotal coupling structure, and is adapted to contact the first position-fixing member when the screen is deployed to hold the screen in any position within the continuous range of possible deployed positions.

Claims

1. A stowable video display system comprising:

a base;

a display screen pivotally coupled to the base, wherein the screen is pivotal about a pivot axis between a stowed position and a deployed position selected from a continuous range of deployed positions;

a pivotal coupling structure pivotally coupling the screen to the base, the pivotal coupling structure including a dampening mechanism adapted to dampen deployment of the screen;

a first position-fixing member mounted on the base; and

a second position-fixing member mounted on the pivotal coupling structure, the second position-fixing member being adapted to contact the first position-fixing member when the screen is deployed to hold the screen in any of the continuous range of possible deployed positions.

2. The display system of claim 1, wherein the second position-fixing member travels along the first position-fixing member as the screen is pivoted between deployed positions.

3. The display system of claim 1, wherein the first position-fixing member includes a curved surface adapted for selected contact with the second position-fixing member throughout the continuous range of possible deployed positions.

4. The display system of claim 3, wherein the first position-fixing member is in sliding frictional contact with the second position-fixing member surface throughout the continuous range of possible deployed positions.

5. The display system of claim 1, wherein the second position-fixing member includes a leaf spring.

6. The display system of claim 5, wherein the leaf spring contacts the first position-fixing member throughout the continuous range of possible deployed positions, and wherein the leaf spring is biased by the first position-fixing member so that the leaf spring exerts pressure against the first position-fixing member to frictionally hold the screen in any position within the continuous range of possible deployed positions.

7. The display system of claim 1, further comprising an urging system that urges the screen to pivot toward the continuous range of possible deployed positions.

8. The display system of claim 7, wherein the urging system includes a spring coupled between the base and the pivotal coupling structure such that the spring urges the pivotal coupling structure to pivot the screen away from the stowed position.

9. In an automobile including a passenger compartment having a ceiling, a video display system viewable by a passenger in the passenger compartment, the video display system comprising:

a display screen pivotally coupled to the ceiling for pivot about a pivot axis between a stowed position adjacent the ceiling and a deployed position within a continuous range of possible deployed positions in which the screen is viewable to the vehicle passenger;

a pivotal coupling structure coupling the screen to the ceiling, the pivotal coupling structure including a screen-coupling portion operatively attached to the screen, a pivot bar operatively attached to the ceiling, and a dampening mechanism to dampen the deployment of the screen relative to the ceiling;

a first position-fixing member operatively attached to the ceiling; and

a second position-fixing member operatively attached to the pivotal coupling structure, wherein the second position-fixing member is adapted to contact the first position-fixing member throughout the continuous range of deployed positions so that the screen is held in any position within the continuous range of possible deployed positions by the contact between the first position-fixing member and the second position-fixing member.

10. The automobile of claim 9, wherein the first position-fixing member includes a curved surface configured to be in slidable contact with the second position-fixing member such that the second position-fixing member slides along the curved surface as the screen travels throughout the range of deployed positions.

11. The automobile of claim 9, wherein the second position-fixing member includes a leaf spring adapted to be biased by contact with the first position-fixing member throughout the range of deployed positions to hold the screen in any of the range of deployed positions.

12. The display system of claim 9, further comprising an urging system that urges the screen to pivot toward the continuous range of possible deployed positions.

13. The display system of claim 12, wherein the urging system includes a spring coupled between the ceiling and the pivotal coupling structure such that the spring urges the pivotal coupling structure to pivot the screen away from the stowed position.

14. In an automobile including a passenger compartment with a rear seat and a ceiling, a ceiling-mounted video display system comprising:

a base attached to the ceiling of the passenger compartment, the base including a curved position-fixing surface;

a screen structure having a viewing surface, wherein the screen structure is pivotally coupled to the base such that the screen structure is pivotable between a stowed position adjacent the ceiling and a deployed position selected from a continuous range of possible deployed positions in which the viewing surface extends downwardly from the ceiling for viewing by a rear seat passenger;

a pivotal coupling structure pivotally coupling the screen to the base, the pivotal coupling structure including a screen-coupling portion attached to the screen structure, a pivot bar attached to the base, and a dampening mechanism to dampen the pivoting of the screen structure, wherein the pivotal coupling structure pivots with respect to the base when the screen structure is pivoted; and

a leaf spring disposed on the pivotal coupling structure such that the leaf spring is in slidable contact with the position-fixing surface throughout the continuous range of deployed screen structure positions to frictionally hold the screen structure in any one of the continuous range of deployed positions.
