[0010] -Determine prohibited areas for seats based on the position of movable objects;
[0011] - moving the seat according to the received command; and
[0012] - Compare the position of each element of the seat to the prohibited area.
[0013] In this patent application, the seat is stopped when it reaches a prohibited area, so that the seat cannot reach a position desired by the user.
[0014] Therefore, it may be desirable to provide a method that avoids at least some of the above-mentioned problems and limitations. Summary of the Invention

[0036] The invention will be better understood from the following description, given by way of example only, made with reference to the accompanying drawings, in which:
[0037] - Figure 1 is a side view of an example of an aircraft furniture installation according to the invention comprising two seats,
[0038] - Figure 2 It is used to control Figure 1 A block diagram of a method for seating in a furniture installation is shown,
[0039] - Figure 3 Shown with Figure 1 The initial seat configuration shown is different from the initial seat configuration,
[0040] - Figure 4 An intermediate configuration of the seat is shown, and
[0041] - Figure 5 The final configuration of the seat is shown. DETAILED DESCRIPTION
[0042] refer to Figure 1 , an example of an aircraft furniture installation 100 according to the present invention will now be described.
[0043] First, the furniture arrangement 100 includes two seats 102A, 102B facing each other. Each seat 102A, 102B includes a plurality of elements, such as a seat cushion 104A, 104B, a backrest 106A, 106B, and a footrest 108A, 108B.
[0044] The seats 102A, 102B are designed to move toward or away from each other in translation relative to the aircraft floor 110 along a direction D. Subsequently, the elements 104A, 106A, 108A, 104B, 106B, 108B of each seat 102A, 102B are considered to remain fixed relative to each other, so that the only movement considered is translation along the direction D. Therefore, it can be considered that each seat 102A, 102B is formed by a single element.
[0045] To this end, each seat 102A, 102B includes a respective actuator 112A, 112B designed to move the seat 102A, 102B over a respective predetermined travel 114A, 114B in a direction D. As shown, the travels 114A, 114B overlap, so the seats 102A, 102B may collide.
[0046] Each actuator 112A, 112B is also designed to transmit the position of the seat 102A, 102B it moves, along a direction D in the example shown. This position is determined, for example, in a Cartesian coordinate system fixed to the floor 110 .
[0047] The position of seat 102B defines a keep-out zone 115 for seat 102A. Keep-out zone 115 surrounds seat 102B and corresponds to a point in space that seat 102A must not occupy in order to avoid colliding with seat 102B. The position of keep-out zone 115 changes as seat 102B moves, e.g., the position of keep-out zone 115 moves as seat 102B moves. Figure 1 In the simple example shown, the exclusion zone 115 corresponds to a half-plane defined by a vertical line segment that moves with the seat 102B.
[0048] The furniture arrangement 100 further comprises a control system 116 connected to the two actuators 112A, 112B for controlling the two actuators 112A, 112B to move the seats 102A, 102B and to receive the position of the seats 102A, 102B.
[0049] For example, the control system 116 is a computer system that includes a data processing unit (such as a microprocessor) and a main memory (such as a random access memory (RAM)) that can be accessed by the processing unit. The computer system may also include a network interface and / or a computer-readable medium, such as a local medium (such as a local hard disk) or a remote medium (such as a remote hard disk that can be accessed via a network interface through a communication network), or even a removable medium (such as a universal serial bus (USB) flash drive, or a compact disc (CD) or a digital versatile disc (DVD)) that can be read by means of an appropriate reader (such as a USB port or a CD and / or DVD drive) in the computer system. A computer program containing instructions for the processing unit is stored on the medium and / or can be downloaded via the network interface. For example, the computer program is intended to be loaded into the main memory so that the processing unit can execute its instructions to implement the steps of the method to be described later.
[0050] Alternatively, all or some of these steps may be implemented in the form of a hardware module, ie in the form of an electronic circuit (eg microwiring), without involving a computer program.
[0051] refer to Figure 2 , an example of a method 200 for controlling seats 102A, 102B will now be described.
[0052] During step 202 , the control system 116 receives a command to move the seat 102A (in the illustrated example, to move the seat 102A translationally in the direction of the seat 102B).
[0053] During step 204 , the control system 116 receives the positions of the seats 102A, 102B.
[0054] During step 206 , the control system 116 determines an exclusion zone 115 for seat 102A based on the position of seat 102B.
[0055] During step 208 , the control system 116 moves the seat 102A according to the received command, ie, moves the seat 102A in the direction of the seat 102B.
[0056] During step 210 , the control system 116 compares the position of the seat 102A to the exclusion zone 115 .
[0057] If the comparison indicates that seat 102A has reached exclusion zone 115, control system 116 determines during step 212 the movement of seat 102B that has moved exclusion zone 115 away from seat 102A. For example, control system 116 includes at least one predefined association that associates movement of seat 102A with movement of seat 102B away from exclusion zone 115. Thus, movement of seat 102B that has moved exclusion zone 115 away from seat 102A is a movement that is associated with the current movement of seat 102A according to one or more predefined associations. Figure 1 In the simple example shown, the control system 116 includes, for example, an association between the forward movement of the seat 102A and the rearward movement of the seat 102B. Thus, in the example shown, the control system 116 selects the rearward movement of the seat 102B.
[0058] In step 214 , the control system 116 moves the seat 102B according to the movement determined in the previous step.
[0059] The method 200 then returns to step 204 and continues this cycle of steps until the seat 102A reaches its final position.
[0060] refer to Figure 3 , at this time, the elements 104A, 106A, 108A, 104B, 106B, 108B of each seat 102A, 102B can move relative to each other. In particular, the footrest and backrest are each designed to pivot relative to the seat cushion to move the seat from the seat configuration to the bed configuration.
[0061] Actuators (not shown) similar to the actuators 112A, 112B are then provided to effect these movements and transmit the positions of the various elements, which are determined in a Cartesian coordinate system fixed to the floor 110, for example.
[0062] In this case, the prohibited area 115 is defined by a plurality of straight line segments, the relative positions of which depend on the relative positions of the elements of the seat 102B.
[0063] Can be applied again Figure 2 The method shown.
[0064] Thus, during step 202 , the control system 116 receives a command to move the seat 102A, for example, from a seat configuration to a bed configuration.
[0065] During step 204, the control system 116 receives the positions of elements of the seats 102A, 102B. For example, the seat 102B is in an intermediate configuration between the seat position and the bed position.
[0066] During step 206 , the control system 116 determines an exclusion zone 115 for the seat 102A based on the positions of the elements of the seat 102B.
[0067] During step 208, the control system 116 responds to the received command (ie, by tilting the backrest and footrest while moving the seat cushion forward (see FIG. Figure 4 )) to move seat 102A.
[0068] In step 210, control system 116 compares the position of the elements of seat 102A to exclusion zone 115. For example, the comparison is performed by comparing at least one critical point of each of at least one element (typically an end point of the element) to exclusion zone 115.
[0069] If the comparison indicates that seat 102A has reached prohibited zone 115 (see Figure 4 , wherein footrest 108A reaches exclusion zone 115), control system 116 determines during step 212 the movement of at least one element of seat 102B that moves exclusion zone 115 away from seat 102A. For example, control system 116 includes at least one predefined association that associates movement of at least one element of seat 102A with movement of at least one element of seat 102B away from exclusion zone 115. Thus, according to one or more predefined associations, the movement of seat 102B that moves exclusion zone 115 away from seat 102A is a movement associated with the current movement of seat 102A. In this example, control system 116 includes, for example, an association between movement toward the bed configuration of seat 102A and movement toward the seat configuration of seat 102B. Thus, in this example, control system 116 selects movement of seat 102B toward its seat position.
[0070] In step 214 , the control system 116 moves the seat 102B according to the movement determined in the previous step.
[0071] The method 200 then returns to step 204 and continues this cycle of steps until the seat 102A reaches its final position (see FIG. Figure 5 ).
[0072] It should also be noted that the present invention is not limited to the embodiments described above. In fact, it will be apparent to those skilled in the art that various modifications may be made to the embodiments described above based on the teachings just disclosed.
[0073] In particular, the roles of the seats 102A, 102B may be interchanged.
[0074] Additionally, the seat 102B may be another movable object that may be moved by the control system 116 , such as a table, a minibar, a dining tray, a screen, and the like.
[0075] In the detailed presentation of the invention given above, the terms used should not be construed to limit the invention to the embodiments set forth in this specification, but should be construed to include all equivalents that a person skilled in the art could anticipate by applying his common sense to the practice of the teachings just disclosed.
