Description

BACKGROUND OF THE INVENTION The present invention relates to a transfer device for a motor handicapped person, in particular a traveler, for example an air traveler in an airport, and the where appropriate, in the airplane. It also relates to elements of this device, including a transfer seat.

It also relates to uses of this device and methods of implementing this device. The transfer of air passengers with motor disabilities, or people having great difficulty to move, presents many difficulties. The passenger, who comes to the airport on his own vehicle, such as a scooter or wheelchair, motorized or not, must go through gates or security installations with magnetic or other detection, the operation of which is incompatible with the presence of this vehicle, as well as with the presence of an airport wheelchair dedicated to disabled passengers for their subsequent transfer in the plane. Similar difficulties arise for land travelers, especially railways.

It has already been planned to use wheelchairs made of non-disruptive synthetic materials for safety detectors. However their use leads to additional transfer manipulations, tiring for the passenger and requiring one or more assistants, and slowing down the filling of the aircraft. After passing through the safety zone, the disabled motor passenger must be transferred to the aircraft using an airport wheelchair-like vehicle into the aircraft aisle and then manually transferred to its seat , the transfer in the opposite direction to be carried out at the airport of arrival. This manipulation requires the presence of two assistants and requires a lot of time.

3037234 2 Various lifting devices have already been proposed to assist these transfers, but these devices are heavy, complicated and bulky, and have not found any real use in practice. The present invention proposes to remedy these drawbacks and in particular to reduce the tiredness of the disabled motor passenger, to lighten the load of the assistants, and to speed up the transfer of the passenger in the transport vehicle, notably such as a plane or train. . It also proposes to facilitate the transfer of persons with disabilities or not being able to move between vehicles and / or seats and / or supports for these persons.

For the purposes of the present invention, the term "motor handicapped" is understood to mean persons with no mobility or reduced mobility and who are mobile or able to move in an individual handicapped vehicle. For example, they are paraplegic persons, or who have lost the use of their legs, or who can not walk with difficulty, for example people suffering from obesity. Also included in this term are people with normal or low mobility, but who get tired or run out of steam very quickly. We also hear people who are sick or under anesthesia. For the purposes of the present invention, the term "individual vehicle for the disabled" is understood to mean wheelchairs, self-propelled or not, scooters for the disabled and tricycles, driven or not by the disabled person himself.

The invention relates to a transfer device for the disabled motor, comprising a set of transferable base for disabled motor, including traveler, for example disabled passenger passenger motor of a transport vehicle, such as in particular an aircraft or a train , comprising at least one upper part, or actual, movable, possibly padded, horizontally movable seat on which the user sits, having an anterior edge, a posterior edge and two lateral edges, at least two lower parts fixable respectively on the seats or supports between which the transfer is to be ensured, in particular on a passenger seat of a transport vehicle, for example an aircraft or a train, and / or on a wheelchair undetectable by detection means for example a non-magnetic wheelchair 3037234 3 and / or an individual passenger car seat icapé dedicated to the transport between the inside and the outside of a transport vehicle, said lower parts each having an anterior edge, a posterior edge and two lateral edges, and comprising, on their upper face, guide means for the Displacement of the upper part on them, essentially in a direction substantially perpendicular to said lateral edges, and thus to the sagittal plane of the passenger seated on said transferable upper part, said guide means cooperating with complementary guiding means presented by the lower face of said upper part, said lower parts optionally but preferably comprising respectively complementary alignment and centering means arranged on at least one of their lateral edges substantially ensuring alignment of their guide means when their lateral edges are arranged substantially side by side, perm then being a lateral displacement of said upper part between said lower parts.

For the purposes of the present invention, a transport vehicle is understood to mean a passenger transport vehicle, such as an aircraft or a train wagon, for example. For the purposes of the present invention, the term "lower part" is intended to mean a part, piece or plate fixed or fixable on an individual vehicle of a handicapped person, or on a transport vehicle seat on which the plate 20 can move, slide or roll. superior, guided way. Upper part means a part, piece or plate on which a disabled motor passenger can sit. The seats or supports may also include seats for cars or taxis, fixed seats, for example, restaurants or theaters, the 25 seats of a dwelling, the seats of devices for elevating disabled persons between floors, patient seats and stretchers, examination or surgical or medical examination tables, beds for the disabled or patients. Particularly preferably, the movable upper part, on which the passenger is seated, comprises releasable immobilization means, preferably by snap-fastening, co-operating with the lower part, which supports it, to immobilize said upper part on the lower part in the final position where the user must be seated. These means may, for example include hooks, reliefs, rods or snap-in beads, releasable by the user or assistant. For example, the movable upper portion may comprise a vertical rod at a posterior corner, pushed downward by a spring, and whose lower end is capable of penetrating into a hole or notch in the upper face of the the underlying lower part, when the two parts are superimposed in the required position, this rod being manually released, being pulled upwards against the spring, preferably manually.

The guiding means may comprise, for example, rails or guides, for example of dovetail or C-section, for example slotted tubes, with complementary slides to prevent or limit the lifting of the upper part of the body. 'seated. Preferably, between the guiding means of the upper part and the complementary guiding means of the lower part, a clearance in the vertical plane and / or in the horizontal plane is provided, the displacement between the upper and lower parts not being possible. however, only in a direction substantially perpendicular to the side edges. Preferably the vertical play does not exceed substantially 2 cm, and the horizontal play 1 to 2 cm. It is thus possible to transfer the upper part of the seat between two lower parts placed end to end but still inclined with respect to each other by an angle in the vertical or horizontal planes. The respectively complementary means for aligning and centering the fixed lower parts arranged on at least one of their lateral edges, may have complementary shapes respectively allowing their edges to be arranged in a substantially precise position when they are brought into positions adjacent. In a first particular embodiment, these complementary alignment and centering means may comprise, on at least one of their lateral edges, one or more male extensions, respectively female recesses, for example rectangular, triangular, trapezoidal or These curves determine a precise alignment of the adjacent lower parts brought against each other in their plane. In this embodiment it is preferred that these extensions and recesses have self-locking complementary shapes. In a second embodiment, these means may comprise one or more rods, preferably sliding, to be retracted horizontally in the part which presents them, and which can penetrate in elongated passages of complementary section extending horizontally in the another part when said parts are brought side by side. Preferably the opening of the passage and or the end of the rod are chamfered or otherwise inclined to facilitate their centering. For example, the rod may terminate at its free end by a ball or sphere while the corresponding elongate passage of the other portion tapers conically towards its opening. In a third embodiment these means comprise complementary bevelled or inclined surfaces carried respectively by the adjacent edges of said lower parts, and causing a relative horizontal displacement between the adjacent lower parts, when they come into contact by vertical component movement, until a precise alignment of the seating guide means of the parts. These surfaces can be in the form of ramps. For example, the lower portions respectively bear parts or zones in the form of a pyramid or dihedron 20 to male quadruple, respectively female, arranged to interpenetrate to complete stop during the vertical movement between them. To ensure perfect centering, inclined or beveled surfaces can extend in several directions. For example they can be in the form of pyramids or sloping roofs with four sides that fit together.

Thus, when a lower part is placed or raised in contact with the other, this interpenetration ensures both the alignment of the parts at the right level. In the various embodiments, the lower parts may, in addition, have, on their edges, horizontal plane rims that can be superimposed when side by side of the parts to determine the alignment of the sides 30 to the same vertical level.

In a particular embodiment, the respectively complementary means for aligning and centering the fixed lower parts may be simple guides capable of being aligned when the two lower parts concerned are positioned edge to edge, substantially at the same level. the movable upper part, on which the passenger can be seated, having a complementary guiding means, for example an elongate slide, the ends of the guides and / or the slide being preferably flared or tapered to facilitate the entry of said means of additional guidance in the guide. It is preferred that the fastening means on vehicles or wheelchairs, such as a non-magnetic wheelchair or a dedicated wheelchair, for example an airport wheelchair designed to introduce the passenger into the aircraft, have means for rapid attachment to these vehicles. for example, straps or suction cups, or complementary self-adhesive strips, of the well-known Velcro type. Preferably, at least one of said lower portions has means 15 for quick attachment to a transport vehicle seat, for example an aircraft, and preferably reversible, for example one or more straps permanently installed or passages, notches or depressions allowing the passage of straps. These straps can be advantageously fixed, preferably permanently, under the lower face of the lower part. Particularly preferably, self-adhesive strips or tapes, such as Velcro straps, and in particular for fabric-covered or textile-covered vehicle seats, can be used with commercially available, self-adhesive fabric strips. Preferably at least one of these lower parts is completely non-magnetic, the upper movable portion of the seat then being also, and more preferably all the upper and lower parts may be non-magnetic. Particularly preferably, the lower parts may comprise releasable fixing means, for example adhesive strips, like Velcro, or pawls, for connecting together two lower parts placed end to end. It can be provided that these fixing means can be implemented only when the two parts are brought edge to edge in substantially aligned position. But, particularly preferably, this connection can be simply provided by complementary self-locking centering means. To facilitate the movement of the upper part of the seat, one of the parts may have rolling means, such as rollers or rollers, allowing the horizontal rolling of the seat relative to the said lower part. . Preferably these rolling means are presented by the upper part, and look down, the lower paries having simple rolling surfaces on which roll said rolling means, the lifting of the upper part relative to the lower part being prevented for example, by the guide means. In another embodiment, the rolling means comprise a plurality of balls distributed either on the lower part, and then looking upwards, or alternatively under the movable upper part, and then looking downwards. In general, it is preferred that the total thickness of the seating means, namely the top plate and base, with the rolling and guiding means, be small, for example less than or equal to 7 cm or even 5 cm. these means having a flat bottom face easy to install and fix on the vehicle such as undetectable chair or dedicated chair, and optionally on an aircraft seat. Vehicles such as non-magnetic wheelchairs and dedicated airport or train station wheelchairs usually have a standard seat height, identical to the height of the aircraft or train seat. It is therefore not, in general, necessary to adjust the vertical levels of the lower plates placed or fixed on the seats, during the transfer of the upper portion of the seat between said lower parts. However, in some cases, transport vehicle, train or aircraft seats, when upholstered, may collapse to a lower level when occupied, especially by a major overweight disabled passenger. The assembly according to the invention may then comprise at least one thin lifting means, for example a flat jack, preferably manually operable, either by the passenger or by an assistant, inserted between the seat proper and the part Lower concerned. This lifting means can be permanently secured to this lower part, but preferably it can be separable and simply fixable under the lower part. Where appropriate, the assembly according to the invention may comprise a raising element, of determined height, which can be inserted under the lower part fixed on the vehicle such as a wheelchair, to be at the same height as the lower part provided with its lifting means and placed on the upholstered chair of the transport vehicle before the latter collapses under the arrival of the passenger. As a variant, the assembly according to the invention may comprise one or more ramps intended to be placed on the ground, for example the floor of the corridor of a transport vehicle, and / or a room, for example a station or an airport. , to bring a vehicle, including a non-magnetic chair or a dedicated chair to the correct height for the alignment of the lower parts concerned. It is thus possible, for example, to bring to the same horizontal level a lower portion provided with an underlying lifting means placed on an aircraft seat and the lower part fixed on the dedicated chair.

Preferably, the width of at least one of the lower parts, fixable on a transport vehicle seat, for example an aircraft seat, is substantially equal to the width of this seat. It is thus possible to put two, three or more lower ends together on seats of a row, making it possible to transfer the passenger, on its moving upper seat part, from the seat juxtaposed to a dedicated chair, to 20 a seat away, for example next to a porthole. The upper portion of the seat may comprise a backrest and / or at least an armrest and / or a footrest. Preferably these elements are easily mountable and removable, to be stored in a small container. The upper and lower parts are easily stackable to be stored in large quantities, in the form of separate batteries, according to their dimensions. In order to facilitate the transfer of a disabled passenger between the vehicle by which it arrives at the airport or boarding station, for example a car, a motor-handicapped scooter, or a disabled person's wheelchair, the assembly according to the invention may also comprise a transfer device, on one side of which can be disposed a vehicle selected from a first group formed by automobiles, and the individual personal vehicles of a disabled passenger, a folding seat, the On the other hand, a vehicle selected from a second group formed by the nonmagnetic vehicles, for example a non-magnetic wheelchair, or otherwise undetectable by the safety detection means, and the individual disabled passenger vehicles dedicated to the transport of passengers, may be disposed of. the interior of an aircraft, said jump seat being located, on one side, in the immediate vicinity of a corresponding side of a seat of the veh icule said first group, and, on the other side, in the immediate vicinity of a corresponding side of a vehicle seat of said second group, or being movable laterally, preferably along jump seat guide means, between two positions located respectively in the immediate vicinity of said vehicle sides when they are immobilized in their respective locations, said folding seat having a lower portion of the seat according to the invention for transferring the movable upper seat part between the lower part situated on the folding seat and the lower part end to end of the vehicle of said second group, and means for vertical displacement 15 seat, allowing a variation of the vertical level of the seat on the jump seat for the alignment of said means of respective guidance. Preferably the different lower parts, said fixed, comprise additional abutment or centering means presented by the folding seat and the vehicle of the second group, and cooperating with each other when the folding seat is located substantially in its transfer position next to the seat. chair and the seat is moved vertically, to ensure the stop vertical movement and alignment of the seat guide means carried respectively by the jump seat and the vehicle. It can also be provided that the vertical movement of the jump seat is set in advance, so as to cause stopping when the vertical displacement reaches the level required for the seat guide means to be in the same horizontal plane. In this case it is also preferred to provide centering and abutment means for bringing said guide means in extension between them. Alternatively, on a vehicle or on a lower part, there may be a light or infra-red source emitting a thin light beam intended to be picked up by an adjacent lower vehicle or plate sensor when the two lower parts have reached the same vertical level, then cause the relative vertical displacement to stop between the two parts. As a variant, it is possible to cause the operation of a light or sound indicator indicating to the handicapped person or to an assistant the obtaining of the correct position. Such light means can be used to indicate the achievement of good alignment of the lower parts.

It is preferred that the seat of the folding seat, with its guide means, can be lowered vertically below the level required for the transfer between seat and chair, so that the abutment and centering means come to cooperate with each other during the uphill movement of the seat. The assembly may comprise, in a room or a parking lot, for example 10 terminal or station, a first determined location in which can be arranged a vehicle selected in said first group, and a second determined location in which can come arranging a vehicle selected from said second group, said jump seat being located between these two determined locations. Preferably, said first location and / or said second location 15 have marking means, or even guiding or abutment, so that the vehicle concerned can easily stop in a position just next to the seat presented or presentable by the jump seat. It can be provided that said location comprises means for immobilizing said individual vehicle. Preferably, in the case where the jump seat moves between said first and second locations, the device comprises means for horizontal guidance of the jump seat, for example rails or slides, between said two locations. In a particular embodiment, adapted in particular to the transfer of patients between stretchers and medical tables, for example, the device according to the invention may comprise at least one set of upper parts and at least two sets of lower parts including a plurality of upper parts assembled together to be transferred between assemblies of lower parts. Preferably the parts of at least one assembly are interconnected at their anterior and / or posterior edges by articulations, preferably lockable at desired angular positions.

The invention also relates to a method for transferring passengers using an assembly according to the invention, and comprising the following steps: at the departure of the disabled passenger, transfer of the passenger to an upper portion of seat arranged on a lower part 5 fixed on an individual disabled passenger car seat dedicated to the transport between the inside and outside of a transport vehicle, moving said dedicated vehicle into the transport vehicle next to and in the immediate vicinity of the seat intended for to the passenger, setting up, before or after said movement, a lower part on said seat, centering the two lower parts end to end, and preferably securing said parts together, transfer from said upper part carrying the passenger to the lower part on said seat, and preferably locking of said upper part, preferably r from said dedicated vehicle, at the arrival of the passenger to his destination, moving a dedicated vehicle carrying a lower part into the transport vehicle next to and in the immediate vicinity of the passenger seat, centering the two lower parts butt , and preferably securing said parts to one another, transfer from said upper part carrying the passenger to the lower part on said dedicated vehicle, exit of said dedicated vehicle out of the transport vehicle, and transfer of the passenger from the dedicated vehicle to a seat of a car or of an individual handicapped vehicle. Preferably, the lower part placed on the seat of the transport vehicle is removed. If the seat intended for the disabled passenger is located in a row of seats and is separated from an access corridor by one or more seats, for example by being located next to a porthole, there is available on the other seats concerned one or more lower parts aligned end to end and the upper part is transferred by moving along said lower parts. In the case where the assembly comprises a device with a folding seat carrying a fixed lower portion of seat, the method may comprise the steps of transferring a disabled passenger arriving by car or in a personal vehicle, to an upper part of the seat. seat located on said lower portion of jump seat, then transfer of said upper seat portion from the jump seat to a vehicle of said second group, and conversely when the passenger set arrived at its destination. In the case where a non-magnetic type of chair is provided, the transfer between a folding seat or a dedicated chair and the non-magnetic chair is also carried out by end-to-end joining of the lower parts with that of the non-magnetic chair, and then horizontal displacement of the seat. upper part of the seat. The invention also relates to the uses of the device according to the invention for the transfer of the motor handicapped, not only for transfers in the cases described above, but also in other cases where several lower parts may be fixed on supports that can be brought side by side for the transfer between them of one or more upper parts, in particular for the following uses: transfer between a vehicle seat, such as a car or a taxi, and a device adapted to be brought to side of a vehicle seat, including a folding seat as defined above; transfer of a person with bedridden or having motor difficulties, for example between a stretcher and a bed or a table of examination or operation, the device then having, preferably, at least two sets of lower parts aligned in the plane Sagittal, fixed or hinged together, and a set of upper parts aligned, fixed or hinged in the same way; transfer between an individual disabled motor vehicle and a non-mobile seat, for example, a chair or armchair for a restaurant, bar or auditorium, or a waiting room.

Referring to Figure 1. The assembly according to the invention comprises a movable upper seat 1, and a lower portion of seat 2. The upper portion 1, plate-shaped, may have a padding (not shown) for the comfort of the disabled passenger 5 engine sitting on it. The upper portion may, optionally, present at each corner, a hole (not shown), in which can be inserted amounts of parts such as backrest, armrest and footrest (not shown). Under its lower surface it has two parallel slides 4 extending between the lateral edges of the seat. As seen in FIGS. 2 and 3, the section of the sliders 4 has an upper base 3 fixed under the plate 1, a vertical core 5 and an angle flange 6. As can be seen in FIGS. 4 and 5, the ends of the slider profiles 4 can be beveled, to facilitate the entry of the sliders 4 into the slideways 13. Referring to FIGS. 2 to 5, it can be seen that the plate 1 has, on its lower face, four rows of six 7. In these Figures, it can be seen that these balls are mounted and freely rotatably retained in corresponding housings 8, of which they protrude in part towards the bottom, these boxes being inserted and locked in vertical cylindrical housings 9 of FIG. Part 1. Such ball packages are commercially available, including non-magnetic materials. Referring to FIG. 1, it can be seen that the lower part 2 has a flat base 10 surmounted by three parallel elements, namely a central element 11 and two outer elements 12 delimiting between them two channels 13 forming two slides parallel to the sliders 4. The elements 12 have, on their inner sides, Z-shaped profiles, 14, whose upper horizontal leg 15 partially overlaps the channel 13 to prevent top extraction of the profiles 4, once inserted into the 25 channels. slide 13. The lower horizontal leg 16 is applied against the base plate 10. The respective dimensions of these parts are such that the top part plate 1 can be raised slightly, for example in a 2 cm gap, before the branches 6 of the slider profiles 4 do not abut against the lower faces of the upper horizontal limbs 15 profiles 14. Dan s of the housings in the two sides of the plate 11, horizontal flat rollers 17 were mounted rotating on vertical axes 18, namely five rollers 17 in as many 3037234 15 housings for each element side 11. A set horizontal is also possible between the plate positions in which the rollers 17 respectively come into contact with the respective vertical webs 5 of the sliders 4, this clearance being preferably limited to 1 cm. The lower ends of the pins 18 are fixed in the base plate 10, and the upper ends in the element parts 11, which form the upper partitions of the plate housings. When the lower and upper parts of the assembly are inclined, for example when the front edge is at a level higher than that of the rear edge, which is the case when the seat of a seat is inclined towards the rear, the rollers 17 of the row 10 of the lowest rollers are pressed against the corresponding profile 4, thus limiting the displacement in the sagittal plane. As a variant, the horizontal rollers may be mounted in the upper part 1, for example by being mounted on the edges 6 of the sliders 4, in order to be able to roll, with the desired horizontal clearance, against the vertical webs of the profiles 14.

The various constituents of parts 1 and 2 are preferably made of rigid non-magnetic materials, in particular of carbon. For example, the plate forming the upper part 1 and the base plate 10 may be polyester plates, and the elements 11 and 12 cut from polyester-wood-polyester composite sheets. The sliders 4 and profiles 14 may be metal, or plastic, the axes of the rollers being metallic or carbon. According to the shapes that are to be given to the lower parts 2, the plate 10 may overflow on both lateral sides, on one of the edges with a recess on the other edge, or be recessed at both edges, or on the one of the edges, the other being to the right of the upper elements. These overflows 19 or withdrawals 20 can ensure the placing at the same vertical level of two lower parts 2, superimposed when these parts are put end to end. On the face of the overflows 19 looking upward, one sticks one or two short sections of self-adhesive tape (not shown), of the Velcro type, and the same is done on the face facing down, withdrawals 20, so that when two parts 2 are placed end to end, with superposition of their overflow and withdrawal 19, 3037234 16 20, this superposition causes the adhesion between them of these strips, and secures said parts 2 against each other against any attempt of separation in horizontal direction. To separate the parts 2, it will be enough to lift the part 2 having the relevant withdrawal 20, with the adjacent part 2, which disengages their respective strips 5, as is known for this type of band. The immobilizing means of the upper part 1 on the lower part 1 have a button 27 emerging from the plate forming the upper part in two diagonally opposite corners, and a hole 28, opposite the lower plate 2, so that in the alignment position a rod (not shown) biased downwards by a spring, comes down into the corresponding hole, this rod being fixed at its upper end to the button 27, so that by pulling the button towards the top one releases the stem. A second diagonally opposite second hole 28 in the upper surface of the part 2 allows the immobilization of the part 1, when the part 2 is turned by 180 °. In order to ensure the centering of two lower parts placed end to end, the lateral edges of the lower parts 2 may comprise, preferably on the central element 11, male extensions 21, respectively of the female recesses 22, thus ensuring alignment of the slides 15 of the two parts, the height alignment being secured by the superposition of the extensions 19 and withdrawals 20. These extensions 21 and recesses 22 may have various complementary shapes 20, as they allow a nesting ensuring the alignment centered of two consecutive lower parts. Preferably, they have substantially rectangular (FIGS. 1, 6, 7), or trapezoidal, or triangular shapes, which allows them to be interleaved by horizontal as well as vertical displacement. However, in a particularly preferred embodiment, shown in FIG. 8, complementary self-locking shapes, for example trapezoidal with a constricted recess opening, are provided, as shown in FIG. 8, which requires the juxtaposition of two parts. 2 consecutive is done by vertical movement, but avoids providing fastening means for securing the parts 2 between them.

In the preferred embodiments, shown in FIGS. 1, 6, 7, or in FIG. 8, the transferable seat assembly of the device according to the invention comprises at least one part 2 or 2a with two recesses. 20 (FIG. 1), at least one portion 2 or 2b with an overflow 19 on one side and a withdrawal 20 on the other (FIG. 6), and optionally, but preferably, at least one portion 2, 2c (FIG. 9) with a recess 20, on one side, the other having neither overflow nor withdrawal.

Referring to FIG. 8, there are shown three aircraft seats 23, 24, 25 of a row, as well as a wheelchair 26 dedicated to the transfer of a passenger in the aircraft, chair height 26 being, generally identical to that of aircraft seats. Also shown in relation to the chair and corresponding seats, the lower parts 2a, 10 2b, and 2c views from above. For the convenience of drawing the seats are spaced from each other, but one must understand that in reality they are adjacent. If the seat intended for the disabled motor passenger is the seat 23, side aisle of the aircraft, a wizard places on the seat 23 a lower portion 2b, it fixed on the seat, for example by straps (not shown). If the seat intended is the central seat 24, it fixes thereon a second lower portion 2b. If the seat intended is the seat 25 side porthole, it poses and fixed on it a part 2c, the parts 2 concerned being centered in their positions by the interlocking extensions and recesses 21, 22 concerned (this nesting is not visible in Figure 8, the seats being shown separately). The superposition of the overhangs and withdrawals 19, 20 concerned ensures maintenance at the same vertical level.

Preferably, these operations are carried out in the following order: if the place of the handicapped passenger is the seat 25, porthole side, it sets up the part 2c on the seat 25; it then sets up a part 2b on the seat 24, bringing its trapezoidal withdrawal 22 around the extension 21 corresponding to the part 2c by a slight tilting or descent; he then sets up another part 2b on the chair 23, proceeding as before. if the passenger seat is the central seat 24, it omits the seat 25 and places a portion 2b or 2c on the seat 24; then he sets up the other part 2b on the seat 23, as before; if the seat of the passenger is the seat 23 on the corridor side, he directly places a part 2b or 2c on the chair 23; 3037234 18 the passenger arrives on a dedicated wheelchair 26, sitting on the upper part 1 (not shown) mounted on the lower part 2a secured to the chair 26, the assistant immobilizing the chair 26 in a relatively precise position next to the seat 23 preferably by means of marks or marks (not shown); he then places the part 2b 5 on the chair 23, by inclining the part 2b to bring its edge side aisle to a lower level than the corresponding withdrawal 20 of the part 2a, after which it brings the part 2b in horizontal position, ensuring the entry, from below, of its extension 21 in the recess 22 of the part 2a until the overflow 19 of the part 2b abuts against the corresponding rim 20 of the part 2a, this operation being facilitated by the 10 possibility of moving a few centimeters part 2b on the seat 23, it being understood that, if parts 2b or 2c are present on the seats 24, or 24 and 25, these parts can follow the slight displacement of the part 2b of the chair 23, thanks to the connections by the extensions and withdrawals 21, 22. The assistant can then easily push the upper part 1, on which the passenger sits, towards the part 2b of the seat 23, then to the others, if take place, as needed in manually preventing snap-fastening of the upper part on the intermediate lower part or parts, the snap then immobilizing the upper part on the final lower part. He may then, after possibly moving the wheelchair, fix the lower part having received the upper part, on the final seat, for example by fixing the self-adhesive tapes of this part on the seat fabric; then, after having removed, if necessary, the intermediate lower part or parts, he may leave with the chair 26. On arrival at his destination, after having, if necessary, placed the part or parts 2b intermediate, he proceeds to transfer in the opposite direction to a dedicated wheelchair 26.

In general, the rigidity of the seats of the aircraft seat is sufficient for the lower part 2 under a passenger of normal weight to descend, under the effect of the slump of the seat, a distance that can be compensated by the vertical clearance. Parts 1 and 2 are different. In the case of height differences between vehicles or seats, under the lower part concerned a lifting means, preferably of low thickness, may be provided in the lowered state. FIGS. 9 and 10 show a lower portion 2 ', for example provided with two rows of rollers 29 on which a seat portion (without balls) can be rolled, guided by slide and slide (no shown). Between the frame 30 of the chair and the lower part 2 'is fixed a lifting device 31, of the worm-jack type 32 and levers 33, of a conventional type, provided with a crank 34 allowing the rise or fall of the plate fixed on the jack. Preferably the thickness of such a jack, in the picked up position, does not exceed 5 cm. Such lifting means may also be provided under each lower portion shown for example in Figure 8, to allow alignment of the lower parts even when the passenger seat in the plane or the train, sags significantly under the weight of the passenger.

Referring now to FIG. 11. The device according to the invention may also comprise, preferably in one or more fixed locations, for example parking or serving of station or airport carriages, a transfer device having a jump seat. 35 movable between a close position of the seat 36 of the disabled passenger, for example in a car or a taxi 37, and a close position next to a vehicle 38 for disabled motor, for example a scooter or wheelchair, including a chair non-magnetic or an armchair, such as 26 dedicated to the transfer to the interior of a train or plane. The jump seat 35, which can be motorized or manually movable, is preferably guided by guiding means, for example rails 39 placed or fixed on the ground, and whose direction 20 is inclined with respect to the longitudinal axis of the car 37. Furthermore the jump seat has lifting means (not shown) to adapt the level of its seat, at the car seat as well as the vehicle, for example a lifting means such as 10. Such devices are described in the patent application WO 2015025038. Preferably, the jump seat 35 carries a lower part according to the invention, for example of the type 2c (not seen in FIG. be brought next to a lower part 2 according to the invention, for example of the type 2a or 2b carried by the vehicle 38. It is thus possible to bring a seat upper portion 1 located on the jump seat, to the immediate vicinity of the seat 36 d e the car or taxi, the transfer between the seat and said part 1 being done manually. The operation is as follows: 3037234 20 After arrival of the car in good position, and opening of the door 40, the jump seat 35 is brought close to the seat 36, in the position of Figure 11, then the vertical level is adjusted to that of the seat; the traveler is then transferred, by his own forces, or with the help of an assistant, to the part 1 carried by the jump seat; the jump seat 5 is then moved on its guides 39, to the side of the vehicle 38, then its vertical level is modified, if necessary, to that of the part 2 of the vehicle. In the case of self-locking extensions and withdrawals 21, 22, it is preferable that the lower part 2 carried by the individual vehicle 38 is not yet fixed, allowing an assistant to put it in a good position centered with respect to the lower part, such as 2c, of the jump seat 35; the seat part 1 is then transferred to the lower part 2 carried by the vehicle 38, then to the modification of the vertical level of the jump seat to disengage the respective centering means, such as 19 and 20, from the vehicle and the vehicle. folding seat; the door 40 can then be closed, and the vehicle 38 can move to another destination.

If the car 37 is gone, a new car is expected with a disabled passenger, a wizard then places on the lower part 2 of the jump seat, a new upper part 1. On return the transfers are made in the reverse order. The device shown in Figure 11 can also be used for transfers between passenger wheelchairs or personal scooters, non-magnetic vehicles, and dedicated vehicles. Referring to Figures 12-17, the upper and lower sets 2 and 2 may also be used as assemblies including a plurality of upper portions 1 assembled together to be transferred between lower portion assemblies 2. the example shown, the device according to the invention is intended to transfer a person between a vehicle on which the person can be seated and a table, for example a medical examination table or imaging. FIGS. 12 and 13 show a lower portion 2 ", similar to the part 2, but each of the two elements 12 has two parallel cylindrical horizontal recesses 41 opening respectively on the front edge of the element 12, and rear of the posterior element 12. In these recesses 41 can be inserted, preferably, slidably, one of the two rods 42 of a hinge 43, so that two lower parts 2 "adjacent in the sagittal plane can pivot relative to each other. Preferably, the joints 43 are provided with means for blocking the angle between their two rods 42, according to the desired angular position. In Figure 14 there is shown a vehicle 44 which can serve as a chair and stretcher for transporting patients. This vehicle has a basic carriage 45 (schematically shown), supporting, by means of hinged arms jacking arm 46, a lower portion 2 "central, on the front and rear edges of which are hinged, by the joints 43, two other parts 2 ", one in the backrest position, the other in the leg support position. If the three parts 2 "are brought into the horizontal position, a stretcher position is obtained, on each lower part 1" a corresponding upper part 1 "is mounted, the transported person resting on them.

To transfer this person to an imaging apparatus table 47, three lower parts 2 ", preferably interconnected, are arranged on the table and have the same spacing between them as that of the parts 2" of the vehicle 44 when they are in horizontal stretcher position. The vehicle 44 is brought next to the table 47 and, if necessary, its vertical level is adjusted by means of the lifting means of the carriage 45, so as to center each part 2 "of the vehicle with respect to the part 2 "corresponding, it is sufficient to push all three upper parts 1", supporting the patient, to the table, to bring them to the corresponding lower parts 2 "arranged on the table 47, after which the vehicle can be moved 44 , if necessary (Figures 15 and 16). The centering between the parts 2 "25 of the vehicle and those of the table can be preset, or we can, after bringing the vehicle next to the table, put on the table, and center manually, each part 2" relative in the corresponding part 2 of the vehicle The whole transfer can be carried out by a single assistant, without significant physical effort, with reference to Figures 17 and 18.

In this embodiment the centering means of the lower parts 2 are arranged to allow centering and alignment directly by vertical displacement of a portion 2a relative to the other, by relative vertical movement between them to the end. arrival at the same vertical level. The side edge of one of the plates has an extension 48, of reduced thickness, having a roof-shaped relief with inclined four-sided faces 49, facing upwards while the edge of the other lower part 2b has a rim. having a recess 51 of complementary shape with four sides facing downwards. The lower portions are first brought approximately end to end, but at different vertical levels, the portion 2a being the lowest, leaving a possibility of relative clearance between the parts in the horizontal plane. When the part 2a is then lifted vertically towards the overlying part 2b, the top of the relief 49 can easily penetrate into the mouth of the recess 51, and the continuation of the rise finally causes a centering and alignment of the two parts. 2a, 2b. even if they initially had angular and horizontal positions slightly offset in the horizontal plane. In Figure 18, the portion 2a has two extensions 48, and the portion 2b two edges 50 with their two recesses, arranged each time on either side of a central slide guide 52 to dovetail section, but it is understood that only one extension, preferably central, is required in the manner shown under reference numeral 12 in FIG. 1 and cooperating with a single rim of the other lower part. It is also understood that this extension can cooperate with recesses 22 of other lower parts for centering without vertical movement, as described in FIGS. 1-8. Such centering means can be particularly indicated during use. a vertically movable jump seat transfer device, as in FIG.
