Abstract

The invention relates mainly to a seat module intended to be installed in an aircraft cabin, having a seat and a tray table that is movable between a folded position and a deployed position, wherein the tray table is also movable in translation and/or in rotation with respect to the seat in order to be moved from the deployed position to an offset deployed position.

First claim

The invention claimed is:

1. A seat module intended to be installed in an aircraft cabin the seat module comprising at least one seat and at least one tray table that is movable between a folded position and a deployed position,
wherein the at least one tray table is also movable in at least one of translation and rotation with respect to the at least one seat in order to be moved from the deployed position to an offset deployed position;
wherein the at least one seat has an axis of extension in a fore and aft direction of the seat, corresponding to a regular sitting orientation of a seat occupant, and the at least one tray table has at least one lateral edge,
wherein the at least one lateral edge is
substantially vertical when the at least one tray table is in the folded position,
inclined with respect to the axis of extension when the at least one tray table is in the deployed position, and
substantially parallel to the axis of extension when the at least one tray table is in the offset deployed position.

2. The seat module as claimed in claim 1 , wherein an axis normal to a rear face of the at least one tray table, when the at least one tray table is in the folded position, is inclined with respect to an axis of extension of the at least one seat.

3. The seat module as claimed in claim 1 , wherein the at least one tray table is also movable in translation in a direction parallel to the axis of extension of the at least one seat about the offset deployed position.

4. The seat module as claimed in claim 1 , further comprising a shell at least partially surrounding the at least one seat, wherein the at least one tray table has a support that is mounted so as to be movable in rotation with respect to the shell via a hinge.

5. The seat module as claimed in claim 4 , wherein the at least one tray table has a plate that is movable in at least one of translation and rotation with respect to the support.

6. The seat module as claimed in claim 1 , further comprising a shell at least partially surrounding the at least one seat.

7. The seat module as claimed in claim 6 , wherein a portion of the shell and a rear face of the at least one seat delimits an internal volume,
wherein the internal volume is accessible through an opening in the shell, and
wherein the opening in the shell is closed off by the at least one tray table when the at least one tray table is in the folded position.

8. The seat module as claimed in claim 7 , wherein a stowing device is positioned inside the internal volume.

9. The seat module as claimed in claim 1 , further comprising
two seats, and
a retractable wall positioned between the two seats.

10. The seat module as claimed in claim 9 , wherein the axes of extension of the two seats are inclined with respect to one another and intersect at a point situated behind the two seats.
