Definitions

• the field of the invention is that of seats for passengers in transport vehicles, in particular aircraft such as airliners.
• the invention relates to an aircraft passenger seat unit having an automatic home position for widening the passage, a seat arrangement comprising such units, as well as an aircraft comprising such an arrangement.
• the invention finds particular applications in the layout of cabins of medium or long-haul airliners, in particular business class aircraft.
• seats convertible into beds have been known for a long time and exist in numerous configurations.
• known seats can also take predefined positions, for example by reclining the seat back to adopt a “relaxation” position.
• seat units comprising a shell surrounding the seat and isolating the seat from a neighboring similar seat are also known.
• a frequent problem in the context of seat densification is that of going from an airplane aisle to the seat, and vice versa. Indeed, when such a passage, also called "egress" in English terminology in the field of air transport, is too narrow, a significant effort must be made by the passenger to reach or leave their seat.
• the present invention aims to remedy all or part of the disadvantages of the state of the art cited above.

• the seat can of course take other positions, at the passenger's choice, such as for example a more reclined relaxation position than the TTL position, or even a bed position. It is then expected that if the passenger gets up from such a position other than the TTL position, the seat returns to the home position.
• the TTL position is the default position when a passenger sits on the seat, with the seat previously in the home position.
• said backrest comprises an upper portion and a movable lower portion configured to be inclined towards said upper portion in said reception position, so as to form a lumbar support zone of a passenger in said reception position.
• the seat back can be “broken” and the transition between the upper portion of the back and the seat is softened.
• a lumbar support zone for the passenger's back is obtained in the home position.
• Such lumbar support significantly increases passenger comfort when seated in a seat in the home position.
• These provisions therefore make it possible to make the seat comfortable in all circumstances, even during the brief moment between the moment when the passenger sits in a seat in the home position, and the transition to the TTL position.
• said lower portion is able to be inclined via a roller fixed pivotally on said seat, and a cam secured to said lower portion of the backrest, said cam having a profile so that said lower portion pivots towards the upper portion of the backrest when the seat is moved towards said seat unit shell.
• the inclination of the lower portion can be carried out without an additional actuator or motorized mechanism, which greatly contributes to a reduction in the economic cost of the unit, as well as to the reduction of its weight.
