Abstract

A seat arrangement, which is in particular designed to be installed in an airplane cabin, includes:
at least one “front” seat unit and at least one “rear” seat unit, positioned one behind the other along a longitudinal axis of the airplane cabin and comprising respectively at least one seat that can pass from a “seating” position to a “bunk” position; a transverse passage arranged between the “front” seat unit and the “rear” seat unit to allow access to an aisle.

The seat arrangement comprises at least partially flexible closure means, said closure means being movable between a stowed position, in which the closure means are unobstructed from the aisle, and a deployed position, in which the closure means obstruct the aisle.

First claim

The invention claimed is:

1. A seat arrangement comprising:
at least one front seat unit and at least one rear seat unit located one behind the other along a longitudinal axis of an airplane cabin and respectively comprising at least one seat capable of passing from a seated position to a bed position,
a transverse passage disposed between the front seat unit and the rear seat unit to allow access to an aisle,
wherein the seat arrangement comprises at least partly flexible closure means, said closure means being movable between a stowed position in which the closure means are clear of the passage and a deployed position in which the closure means close the passage,
the closure means comprising a curtain and a return device for returning the curtain to the stowed position so as to create tension on the curtain when the curtain is in the deployed position,
the return device comprising a single roller provided with a single shaft around which at least part of the curtain is wound when the curtain is in the stowed position,
wherein the curtain comprises a technical part made of a first fabric and an aesthetic part made of a second fabric, wherein the second fabric is thicker than the first fabric, wherein the aesthetic part is attached to the technical part and comprises patterns,
wherein only the technical part is wound around the shaft when the curtain is in the stowed position, the aesthetic part being not wound around the shaft when the curtain is in the stowed position,
the seat arrangement further comprising at least one translational guide for the curtain that is attached to the front seat unit,
said translational guide cooperating with an edge of the curtain,
said translational guide comprising a housing of complementary shape to a profile attached to the curtain,
the curtain comprising stiffening means extending along the edge of the curtain,
the stiffening means being arranged at least partly in the aesthetic part of the curtain.

2. The seat arrangement according to claim 1 , wherein the roller is attached to the front seat unit.

3. The seat arrangement according to claim 1 , further comprising means for holding the curtain in the deployed position, wherein the means for holding the curtain comprise a handle configured to cooperate with a support carried by the rear seat unit or a magnetic device.

4. The seat arrangement according to claim 1 , wherein the stiffening means extend beyond the at least one translational guide.

5. The seat arrangement according to claim 1 , wherein the roller is arranged between a backrest and a fixed shell of the rear seat unit.

6. The seat arrangement according to claim 1 , further comprising means for generating a light pattern.

7. The seat arrangement according to claim 6 , wherein the means for generating a light pattern comprise a light source and translucent wires arranged in a thickness of the curtain.

8. The seat arrangement according to claim 6 , wherein the means for generating a light pattern comprise a light panel arranged inside the curtain.

9. The seat arrangement according to claim 6 , wherein the means for generating a light pattern comprise an assembly of lamps.

10. The seat arrangement according to claim 6 , wherein perforations made in the curtain allow a desired pattern to appear.
