It is proposed that the bench unit, in at least one seat position, have at least one bench unit section which projects rearward beyond the seat unit in relation to the seat unit longitudinal direction. The term. “bench unit” is intended, in particular, to mean a unit which has at least one bench unit surface. In particular, the bench unit surface is designed as a seating surface. The bench unit surface is preferably designed as a lying surface. In particular, the bench unit is designed as a piece of side furniture for the seat unit. In an upright position of the seat unit, the bench unit is preferably arranged at one side of the seat bottom unit of the seat unit in relation to the transverse direction. In particular, the bench unit is arranged at least in large part laterally adjacent to the seat unit in a transverse direction oriented at least substantially perpendicular to a seat unit longitudinal direction. In at least one upright seat position, referred to as the normal position, in which a backrest unit of the seat unit is oriented at least substantially perpendicular to a floor, in particular to a stand surface of the seat unit, a major part of the bench unit is preferably arranged laterally adjacent to the seat unit in relation to the transverse direction. In particular, the major part of the bench unit is arranged laterally adjacent to the seat unit in relation to the transverse direction in at least one seat position, referred to as the comfort position, in which a backrest unit of the seat unit is oriented at least substantially parallel to the floor. In particular, the bench unit is arranged adjacent to a side region of the seat unit.

In an upright position of the seat unit, in which the backrest unit is oriented at least substantially perpendicular to a floor, the sitting direction is oriented at least substantially parallel to the floor and at least substantially perpendicular to the backrest surface formed by the backrest unit. If the seating device is used for an aircraft passenger seat, the sitting direction typically corresponds to the direction of flight.

The phrase stating that the bench unit section of the bench unit “projects rearward beyond the seat unit in relation to the seat unit longitudinal direction” in at least one seat position is intended, in particular, to mean that, in the seat position, a tangent to one side of the seat unit in which the backrest unit of the seat unit is arranged intersects the bench unit and divides it into at least two sections, wherein one of the sections is arranged on a side of the tangent situated in the seat unit longitudinal direction, and the bench unit section which projects rearward beyond the seat unit in relation to the seat unit longitudinal direction is arranged on a side of the tangent opposite the side of the tangent situated in the seat unit longitudinal direction. In particular, the tangent to the side of the seat unit in which the backrest unit of the seat unit is arranged is oriented at least substantially parallel to the transverse direction. The word “provided” is intended, in particular, to mean specifically designed and/or equipped. By means of an embodiment according to the invention, it is advantageously possible to provide a vehicle seat having as much room as possible for a passenger, in particular even when the seats are placed close together in a passenger cabin in which the vehicle seat is arranged, thereby making it possible to increase comfort for the passenger. Moreover, it is advantageously possible to use a vehicle seat flexibly as a seating surface, as a lying surface and/or as a deposition surface. It is furthermore advantageously possible to make available the bench unit as a storage space for objects belonging to the passenger.

In particular, a passenger lying on the lying surface lies at an angle to the seat unit longitudinal direction, preferably to the sitting direction, in particular to the direction of flight. Preferably, the passenger lying on the lying surface lies at an angle across the seat bottom unit of the seat unit. In particular, the passenger lying on the lying surface lies obliquely across the seat bottom unit of the seat unit. The phrase stating that the lying surface longitudinal direction is oriented at an angle to the seat unit longitudinal direction is intended, in particular, to mean that the lying surface longitudinal direction of the lying surface and the seat unit longitudinal direction of the seat unit intersect. In particular, the lying surface longitudinal direction of the lying surface and the seat unit longitudinal direction of the seat unit enclose a smallest angle in a range of from 0° (excluding 0°) to 90°, inclusive. The lying surface longitudinal direction of the lying surface and the seat unit longitudinal direction of the seat unit preferably enclose a smallest angle in a range of from 15° to 45°.

In particular, the bench unit has at least two different bench unit transverse extents in respect of a bench unit transverse direction. The bench unit preferably has one of the bench unit transverse extents in a rear section in relation to a bench unit longitudinal direction, in particular in the bench unit section, and has another of the bench unit transverse extents in a further bench unit section arranged offset in the bench unit longitudinal direction. In particular, the further bench unit transverse extent is less than said bench unit transverse extent. The further bench unit transverse extent is preferably less than said bench unit transverse extent by a factor of more than two. In particular, the further bench unit transverse extent is less than said bench unit transverse extent by a factor of more than three. The further bench unit transverse extent is preferably less than said bench unit transverse extent by a factor of more than four. The term “bench unit longitudinal direction” is intended, in particular, to mean a direction which is oriented at least substantially parallel to a bench unit longitudinal extent.

The bench unit section of the bench unit preferably has a bench unit transverse extent of a magnitude which is greater than a magnitude of a bench unit transverse extent of the bench unit in the further section of the bench unit. By means of an embodiment according to the invention, it is advantageously possible to achieve a tapering profile of the bench unit transverse extent, thereby making it possible to achieve a bench unit which is pleasantly matched to a body geometry of a passenger lying on the bench unit in relation to the bench unit transverse direction.

It is furthermore proposed that the seat unit have at least one lower leg support unit and the at least one seat bottom unit, which are arranged at least substantially in one plane in at least one seat position. The phrase stating that the lower leg support unit and the seat bottom unit are “arranged at least substantially in one plane” in at least one seat position is intended, in particular, to mean that the lower leg support unit has a lower leg support unit surface, more than 70%, preferably more than 80%, and, in particular, more than 90%, of which is arranged in a plane defined by the seat bottom unit. By means of an embodiment according to the invention, it is advantageously possible, in the seat position, for a passenger sitting on the seat bottom unit of the seat unit to rest his legs on the lower leg support unit of the seat unit with his legs comfortably stretched out.
It is furthermore proposed that the lower leg support unit and the seat bottom unit form the lying surface with the bench unit surface in the seat position.

It can likewise be seen that the partition wall 52 screens off a space at the disposal of the passenger using the seating device 12. The partition wall 52 partially forms the space at the disposal of the passenger using the seating device 12. FIG. 3 furthermore clearly shows an angled orientation of the seat unit longitudinal direction 18 and of the lying surface longitudinal direction 30.
It is conceivable for the seat unit 14 to be movable into a seat position in which the seat unit 14 has a substantially Z-shaped profile when considered in a side view. More specifically, it is conceivable for the Z-shaped profile to be set by the passenger sitting on the seating device 12. This Z-shaped profile is referred to as the lazy-Z position. It is conceivable for the seat position referred to as the lazy-Z position to be set by means of the seat unit 14 of pivotable design. More specifically, it is conceivable for the seat position referred to as the lazy-Z position to be set by means of a combined pivoting movement of the seat bottom unit 26, of the lower leg support unit 38 and of the backrest unit 50. It is conceivable here for the Z-shaped profile to be set by the passenger sitting on the seating device 12.
