Abstract

A seating structure includes a seat cooperating to define a space below the seat and at least one supporting member for supporting the seat. An armrest is movably mounted to the supporting member such that the armrest is movable between a first position, in which the armrest is positioned on a lateral side of the seat in an upright manner, and a second position, in which the armrest is positioned in the space such that it does not extend outwardly from the space. The armrest is movable to the second position for allowing the seating structure to be arranged with an identical seating structure in a side-by-side manner so as to form an array of seating structures.

Claims

1. A seating structure comprising a seat cooperating to define a space below said seat;

at least one supporting member for supporting said seat; and

an armrest movably mounted to said at least one supporting member such that said armrest is movable between a first position, in which said armrest is positioned on a lateral side of said seat in an upright manner, and a second position, in which said armrest is positioned in said space such that it does not extend outwardly from said space, said armrest being movable to its said second position for allowing said seating structure to be arranged with an identical seating structure in a side-by-side manner so as to form an array of seating structures.

2. The seating structure of claim 1, further comprising moving means for permitting said armrest to move between its said first and second positions.

3. The seating structure of claim 2, wherein said moving means includes at least one track extending along a direction generally parallel to a longitudinal axis of said seating structure.

4. The seating structure of claim 3, wherein said moving means includes at least one wheel connected to said armrest, said at least one wheel being engageable with said at least one track.

5. The seating structure of claim 4, wherein said seat has first and second opposing sides extending generally parallel to said longitudinal axis;

and wherein said at least one track includes a first track, which extends generally along said first side of said seat, and a second track, which extends generally along said second side of said seat.

6. The seating structure of claim 5, wherein said at least one wheel includes a first wheel engageable with said first track and a second wheel engageable with said second track.

7. The seating structure of claim 6, wherein said at least one track includes a third track, which extends along said first side of said seat, and a fourth track, which extends along said second side of said seat.

8. The seating structure of claim 7, wherein said at least one wheel includes a third wheel engageable with said third track and a fourth wheel engageable with said fourth track.

9. The seating structure of claim 8, wherein said at least one supporting member includes a first support panel, which is located adjacent said first side of said seat, and a second support panel, which is located adjacent said second side of said seat, said first and second support panels cooperating with said seat so as to define said space.

10. The seating structure of claim 9, wherein said armrest includes a supporting unit, said first and third wheels being mounted on one end of said supporting unit, and said second and fourth wheels being mounted on an opposite end of said supporting unit.

11. The seating structure of claim 10, wherein said first and third tracks are formed in said first support panel;

and wherein said second and fourth tracks are formed in said second support panel.

12. The seating structure of claim 10, wherein said first and third tracks are mounted to said first support panel;

and wherein said second and fourth tracks are mounted to in said second support panel.

13. The seating structure of claim 4, wherein said at least one track includes a vertical section, which extends in a vertical direction, and a horizontal section, which extends from said vertical section in a horizontal direction.

14. The seating structure of claim 13, wherein said at least one wheel is located in said vertical section when said armrest is positioned in its said first position;

and wherein said at least one wheel is located in said horizontal section when said armrest is positioned in its said second position.

15. The seating structure of claim 14, wherein said seat has first and second opposing sides extending generally parallel to said longitudinal axis;

and wherein said at least one track includes first and second tracks, which are located adjacent said first side of said seat, and third and fourth tracks, which are located adjacent said second side of said seat; and

wherein said at least one wheel includes first and second wheels engageable with said first and second tracks, respectively, and third and fourth wheels engageable with said third and fourth tracks, respectively.

16. The seating structure of claim 15, wherein said at least one supporting member includes a first support panel, which is located adjacent said first side of said seat, and a second support panel, which is located on said second side of said seat, said first and second tracks being connected to said first support panel, and said third and fourth tracks being connected to said second support panel.

17. The seating structure of claim 16, wherein said first wheel has a size smaller than that of said second wheel;

and wherein said third wheel has a size smaller than that of said fourth wheel.

18. The seating structure of claim 14, wherein said at least one track includes a pivot section connecting said vertical section to said horizontal section for permitting movement of said at least one wheel between said vertical and horizontal sections.

19. The seating structure of claim 1, further comprising a second armrest movably mounted to said at least one supporting member such that said second armrest is movable between a third position, in which said second armrest is positioned on an opposite lateral side of said seat in an upright manner, and a fourth position, in which said second armrest is positioned in said space such that it does not extend outwardly from said space, said second armrest being movable to its said fourth position for allowing said seating structure to be arranged with an identical seating structure in a side-by-side manner so as to form an array of seating structures.

20. The seating structure of claim 19, further comprising second moving means for permitting said second armrest to move between its said third and fourth positions.
