Description

AIRCRAFT MOBILITY SYSTEM FOR PASSENGERS

FIELD OF THE INVENTION

The present invention relates to an aircraft own mobility system for passengers with reduced mobility, with a cabin segment for an aircraft and with an aircraft.

BACKGROUND OF THE INVENTION

In the case of aircraft that are used to transport passengers, the movement of the passengers on board the aircraft also occurs, especially with longer travel times. The movement of passengers serves, for example, to use a toilet located on board the aircraft. Passengers with reduced mobility (referred to as passenger s with reduced mobility, PRM), for example, a wheelchair can be used for this, for use on board a

Aircraft, is tailored. For example, the wheelchair is collapsible and can be stowed folded up to save space. Such a wheelchair for use on board an aircraft, which is also known as an onboard wheelchair, OBW, for example, can be designed to be narrower than a conventional wheelchair, for example, to be moved within an aircraft cabin along the corridor areas. Due to the spatial situation may be the use of a wheelchair aboard an aircraft sometimes subject to severe restrictions; In particular, the use of a toilet can be a troublesome for a passenger with reduced mobility. In WO 2014/154758 AI, for example, an additional seat device is described in order to support a transfer from a wheelchair to the toilet.

SUMMARY OF THE INVENTION

An object of the present invention is to assist passengers with reduced mobility on board aircraft and to simplify the use of an on-board toilet as much as possible.

This object is achieved by the subject matter of the independent claims. Further embodiments are described in the dependent claims. It should be noted that the following described aspects apply to the aircraft's own mobility system, to the cabin segment for an aircraft and to the aircraft.

According to the invention, an aircraft-owned mobility system is provided for passengers with reduced mobility. The on-board mobility system includes an on-board toilet room unit and a moving device. The on-board toilet room unit has an entrance zone with an entrance door and a toilet utility zone with a toilet. The movement device has a passenger carrier device which is held in the ceiling region and which is movable at least from the entry zone to the toilet utility zone. The passenger carrier device has a seat device which allows a passenger a seat-like posture. For the use of the toilet, a passenger is movable by means of the movement device from the entrance zone to the toilet useful zone and back.

The 'mobility system' for passengers with reduced mobility may also be referred to as a cabin-space transport system for passengers with reduced mobility. The mobility system may also be referred to as a toilet transfer system or as a toilet transfer system. The use of the toilet is not restrictive, but there are other supply and disposal facilities in a toilet room, such as the toilet, the sink, soap dispenser, etc., available for the passenger with reduced mobility, depending on disability with or without additional assistants. For example, the term "passengers with reduced mobility" refers to

Passengers who rely on a wheelchair. The term also refers to passengers who can go independent, but who depend on aids. The limited mobility may have various causes, e.g. a physical disability of the passenger, a generally weakened condition, an age-related reduced health condition or the like. The mobility can be permanently or even temporarily limited.

The term "aircraft-owned" refers to a mobility system that is permanently on board the aircraft. The on-board mobility system may also be referred to as an onboard or onboard mobility system, or as an onboard mobility system, OMS, or onboard transfer system, OTS.

The "on-board toilet room unit" is also referred to as lavatory or on-board toilet. The term "entrance zone" refers to that area of the lavatory, i. the toilet room unit in which the toilet is housed, and the room areas occupied by the passenger during toilet use. In other words, the "toilet utility zone" refers to the space used by the passenger when using the toilet.

The "movement device" refers to a system that allows a passenger to be moved aboard the aircraft. The movement device can also as

Transportation device to be called. The movement refers to the movement of the passenger on board the aircraft, ie the movement within the aircraft in relation to the aircraft. This type of movement is not to be confused with the movement of the aircraft in relation to the environment. The "passenger-carrying device" refers to a device capable of carrying, ie, lifting, a passenger. The "seat device" refers to a device in which a passenger can be seated. The term "sitting" refers to a passenger's posture in which the upper body is upright, with angled legs and down-facing or down-facing feet. The passenger does not necessarily have to sit on the buttocks; the load transfer takes place, for example, via support components on the back and thighs.

The term "suspended in the ceiling area" refers to a passenger-carrying device suspended from above. Thus, the seat device is not fixed to the ground and does not stand on the ground, but the load is turned upwards, i. in the ceiling area, worn.

The movement device allows, for example, a passenger otherwise seated in a wheelchair without using the wheelchair to use the toilet room, including the use of the toilet itself. The seat device thereby ensures sufficient support, so that passengers with reduced mobility, for example with paralyzed legs, in the seat device can be kept. For example, passengers may cause movement through the arms within the on-board toilet room unit. As a result, a wheelchair, e.g. an onboard wheelchair, does not have to be included in the on-board toilet room unit.

According to one example, the movement device has a rail extending in the ceiling region, in which the passenger support device is held movably. The rail runs in the interior of the on-board toilet room unit on the ceiling at least from an area above the entrance zone to an area above the toilet. The term "area above the entrance zone" refers to an area that is, for example, above the door opening space (in the case of a door rising inwards - into the interior). The "area above the entrance zone" is arranged, for example, above the floor area on which a user stands when he has entered the room unit. It is essential that the passenger carrier device is reached from here and can be used.

In one example, the passenger carrier, i. the seat device of

Passenger carrying device, usable from an area which is located immediately in front of the door opening of the on-board toilet room unit.

The term "above" refers to e.g. on the vertical projection of the area upwards. According to one example, the rail in the ceiling area extends beyond the area above the entrance zone into a corridor area in front of the on-board toilet room unit. The passenger carrier device is movable into the corridor area. The rail thus not only runs within the on-board toilet room unit, but extends into the corridor area, i. from the ceiling area in the on-board toilet room unit to the ceiling

Ceiling area of the corridor area. A passenger in a wheelchair can thus already change in the corridor area of the wheelchair in the seat device to

then be moved with the seat device in the on-board toilet room unit. This allows, for example, that the transfer from the wheelchair, e.g. an OBW in the seat device must not be made directly in the field of the toilet door, but in a corridor area where the wheelchair for the duration of the toilet use may remain. The handling of the toilet door is simplified by the

Passenger carrier device can be moved to the corridor area.

According to one example, the rail extends in the ceiling area from the hall area in front of the on-board toilet room unit to a cabin area with at least one

Passenger seat. The passenger carrier device is movable into the cabin area. The Rail thus not only extends from within the on-board toilet room unit to the hall area, but extends to an area of the cabin or the aircraft interior, in which at least one passenger seat is provided, ie from

Ceiling area in the on-board toilet room unit over the ceiling area of the corridor area to the ceiling area near passenger seats. For example, the rail extends into an area above the seating area of a passenger seat. A passenger can thus already switch from the passenger seat in the seat device to

then to be moved with the seat device in the on-board toilet room unit or to move using the seat device in the on-board toilet room unit. The use of a wheelchair for the purpose of a toilet use can then be omitted.

The load transfer of the passenger carrier device takes place, for example, via a

Connection to the structure of the aircraft, e.g. to the hull construction. The

Load transfer can also be achieved by a connection to the monument or module, e.g. the toilet module, done.

For example, the rail running in the ceiling area is connected to the secondary structure or directly to the primary structure. The primary structure designates the

Hull structure of the aircraft. The secondary structure designates a subordinate structure intended for attachment of components, equipment, installations, etc., e.g. for the connection of equipment carriers, luggage compartments, monuments etc. The

Secondary structure is attached to the primary structure.

The room zone of the on-board toilet room unit can also be referred to as WC zone. The area in front of the on-board toilet room unit and adjoining corridor areas can also be referred to as a corridor, corridor or corridor zone. The range of passenger seats can also be referred to as a seating area.

In one example, in the hall area or cabin area, mobile partitions are provided as privacy screens to at least optically decouple or shield the area in which the passenger changes into the seat device from other areas. According to one example, the on-board toilet room unit has a sink, and a passenger in the seat apparatus can also use the sink. According to one example, the movement device has a traversing device, which is movable in the horizontal direction, and on which the passenger carrier device is held.

According to one example, the traversing device has a movement unit which is movable along the rail extending in the ceiling region.

According to one example, the movement unit is provided as a carriage, which has two pairs of rollers whose axes are held pivotable relative to one another via a central part.

According to one example, the movement unit is provided as a carriage, which has two pairs of rollers, between which a locking plate is provided, which in operation is partially above inwardly projecting projections of a lower

Rail segment is located. The passenger carrier device is held on the backup plate.

The movement unit is, for example, a self-propelled slide, which is held vertically by the rail and with which the passenger-carrying device is moved in the horizontal direction.

The rail may also be referred to as a transfer rail or mobility ceiling rail.

In one example, the moving unit is provided as a self-propelled slide with an electric drive. The electronics and the electric motors of the carriage, for example, operated with storage elements for storing electrical energy become. For example, the memory elements are formed with charging interfaces, which are in contact with electrical power sources at the end points of the rail, in order to charge the storage elements at least when required. The electronics and the electric motors of the carriage can also be operated alternatively or additionally directly via an electrified rail.

In one example, a control unit for the movement unit is provided on the seat apparatus. The held passenger and / or assistant is thus able to control the movement process, i. to control and control the transfer process.

According to one example, the seat device is kept movable in height.

In one example, it is provided that the movement device a

Lifting device with which the seat device is movable in the vertical direction.

According to one example, the seat device comprises a seat loop device, which can be temporarily folded over to a passenger. The seat loop device has e.g. two leg loops and a back support on and allows a seated posture of the user, in the buttocks area no cover is provided, so that the use of a toilet is possible.

Seat loop devices may e.g. a seated passenger can be folded by, for example, the loop device can be pulled through below the thighs. This can be a seated passenger with a flexible

Carrying stand are provided to lift the passenger from the seat and then to accomplish the transfer to the on-board toilet room unit.

According to one example, the seat apparatus has two guying devices to temporarily lower the seat device at two spaced apart support points unclamp. The breakpoints are provided in the floor area, and / or on a seat structure, and / or on a monument structure, and / or on a cabin wall.

According to the invention, a cabin segment for an aircraft is also provided. The cabin segment comprises at least a portion of a lounge unit having a lounge area with a plurality of passenger seats. In addition, the cabin segment has at least one corridor area for moving the passengers within the cabin segment. Furthermore, an on-board toilet room unit is provided with a toilet. For the on-board toilet room unit, an on-board mobility system according to one of the previously described examples is provided. A passenger with reduced mobility is able to use the toilet during the stay in the cabin segment by means of the aircraft's own mobility system.

In one example, the cabin segment is part of a cabin structure of an aircraft.

According to the invention, there is also provided an aircraft having a residence area with a plurality of passenger seats, and an aircraft-own mobility system according to one of the aforementioned examples. A passenger with reduced mobility is able to use a toilet while on board the aircraft using the aircraft's own mobility system.

The lounge area is part of an aircraft interior.

In one example, the aircraft is an airliner and the occupancy area is formed by a cabin area. The aircraft's own mobility system is in the

Cabin area arranged.

According to one aspect of the invention, a mobility system is provided by means of which a passenger can be moved from an entrance area of an on-board toilet room unit to a toilet for the use of the toilet. For this purpose, a down-hanging construction is provided, the passenger in the manner of a carrying or Tethers is folded, and in which he is sufficiently held. The passenger can thus be moved within the space provided for movement, for example from

Entrance area of a toilet to the area in the immediate vicinity of the toilet for their use. The mobility system can also be provided, for example, in aisle areas, or can extend as far as passenger seats. This allows a passenger with reduced mobility, the use of the toilet, without the passenger must first be put into a wheelchair, then laboriously must be lifted from the wheelchair to the toilet seat.

Rather, only the seated from above seat device must be applied to the passenger.
