Description

Title of the invention: Folding dining table set with sliding flap and seating unit comprising such a set. Technical field

[0001] The present invention relates to the field of aircraft cabin interior fittings, in particular deployable dining tables. It relates more particularly to a retractable dining table assembly with a sliding flap and a passenger seat unit comprising such an assembly.

[0002] The invention finds a direct, but not exclusive, application in the passenger seats of the upper classes (business class and first class) of commercial aircraft. State of the art

[0003] Deployable dining tables installed in aircraft seats date back to the very beginning of commercial aviation. This innovation allowed passengers to enjoy a more comfortable space for eating their meals during flights. Since then, deployable dining tables have become a standard feature in many commercial aircraft.

[0004] US patents 10232946 (ergonomic table with integrated storage drawer) and 10625649 (extendable table with hinged tops) illustrate some examples of dining tables.

[0005] Historically, dining tables have been designed to be deployed from an armrest positioned along the seat, a console located laterally adjacent to the seat, or the back of the seat positioned directly in front of it. In each of these configurations, it is necessary to move the table between a stowed position and a deployed position. Tables that deploy from an armrest or console require complex hinges to change the table's orientation for storage and use, for example, to move it from a vertical to a horizontal position. Also, tables that deploy from beneath a static front structure often require linear forward and backward movement.Since most static front structures have a different height than the ergonomic height of a dining table, complex mechanisms are needed to extend the table towards the user and lower it to the appropriate ergonomic height.

[0006] These complex mechanisms can sometimes remain visible in the environment of the seat, including in the table's stowed position, which detracts from the aesthetic harmony of the seat.

[0007] Some solutions nevertheless offer simplified and lighter mechanisms which are less visible, but without managing to conceal the entire table when it is in the stored position.

[0008] Indeed, the dining tables of the prior art visually stand out from the overall seat design. This aesthetic dissonance can disrupt the harmony of the cabin's interior layout and create a visually inconsistent experience for passengers.

[0009] Furthermore, traditional dining tables may lack visual integration with the rest of the seat environment. Their design may not blend seamlessly with the lines and shapes of other seat elements, which can create an impression of imbalance or a lack of attention to detail in the cabin design, especially in first class.

[0010] Furthermore, traditional dining tables can often be perceived as functional additions rather than integrated design elements. Their appearance may seem utilitarian and unattractive.

[0011] It should be noted here that aesthetics is an essential component in technical development programs for solutions for aircraft cabin interior design. The challenge is to improve the integration and ergonomics of the various equipment in a passenger seat environment, especially in premium classes. Summary of the invention

[0012] The present invention aims to overcome all or part of the disadvantages of the prior art described above, by proposing a solution allowing for a retractable dining table, fully integrated into the design of the seating environment and easy to use.

[0013] To this end, the present invention relates to a table assembly for an aircraft seat, comprising a horizontally deployable tray facing the seat, to allow, in particular, a passenger seated in said seat to eat a meal, and an actuating mechanism for storing and deploying said tray. This table assembly is remarkable in that it comprises a sliding flap perpendicular to the plane of the tray and having a closed position, in which the tray is completely concealed behind said flap in a storage compartment, and an open position configured to release the actuating mechanism and automatically eject the tray from said storage compartment.

[0014] The sliding flap thus allows the tray to be completely retracted when not in use, thereby contributing to a more harmonious aesthetic appearance in the seating environment.

[0015] In addition, the automatic ejection of the tray when the flap is opened simplifies the process for passengers, allowing them to deploy the tray with great ease.

[0016] According to one aspect of the invention, the sliding flap has a shape that perfectly matches the apparent shape of an element of the seat environment, for example a console adjacent to the seat.

[0017] According to an advantageous aspect of the invention, the sliding flap has a stable open position allowing the tray to be revealed without causing movement of said tray, and an additional sliding of said flap beyond the stable open position allows the tray to be ejected.

[0018] This provides passengers with easy access to the tray without causing it to move unintentionally. This feature ensures a smooth and secure user experience, preventing any risk of the tray being deployed unexpectedly. Furthermore, the additional sliding mechanism, which triggers the automatic ejection of the tray, offers intuitive and convenient functionality for passengers.

[0019] More particularly, the additional sliding of the flap for the ejection of the tray has a sliding distance less than the sliding distance between the closed position and the stable open position of said flap.

[0020] Indeed, the sliding distance required for tray ejection is less than that required to move from the closed mode to the stable open position of the flap. This feature allows for easier handling of the tray actuation mechanism.

[0021] According to one embodiment, the ejection of the tray under the effect of the opening of the sliding flap is partial, said tray remaining partially in its storage housing.

[0022] Passengers can thus easily grasp the ejected part of the tray and pull it out completely, making the deployment process more ergonomic and controlled.

[0023] According to one embodiment, the platform is extendable and comprises a base and an extension hinged on said base.

[0024] This design allows the size of the tray to be adapted according to the passenger's needs, thus offering increased flexibility when using the meal table in flight.

[0025] According to one embodiment, the platform is fixed to a curved support whose movement between a fully stored position and a fully deployed position induces a 90° rotation of the platform within its plane. Thus, the platform can be stored longitudinally and deployed transversely relative to the seat, all within the same plane.

[0026] According to one embodiment, the sliding flap has a recess allowing a passenger to manually actuate the sliding of said flap.

[0027] According to one embodiment, the actuation mechanism includes a locking system and an ejection spring, said locking system comprising an articulated lever and latch which are configured to release the tray when the flap is in the open position and thus allow the ejection spring to eject said tray.

[0028] The invention also relates to an aircraft passenger seating unit, comprising a seat, a console adjacent to the seat, and a table set as shown.

[0029] According to a particularly advantageous embodiment, the table assembly is integrated into the console and blends into its shape.

[0030] The fundamental concepts of the invention having been set out above in their most elementary form, other details and features will become clearer from the reading of the following description and with regard to the attached drawings, giving by way of non-limiting example an embodiment of a folding table assembly, in accordance with the principles of the invention.

[0039] It should be noted that certain technical elements well known to those skilled in the art are recalled here to avoid any insufficiency or ambiguity in the understanding of the present invention.

[0040] In the embodiment described below, reference is made to a retractable dining table assembly, primarily intended to equip a passenger seat in business or first class of a commercial aircraft. This non-limiting example is given for a better understanding of the invention and does not preclude the use of the table assembly in other environments, including outside of a transport vehicle.

[0041] In the context of the invention, the term "dining table" or simply "table" refers to a folding or deployable tray integrated into the seat environment, providing passengers with a stable space to eat their meals, place their drinks, or use electronic devices. The table can be adjusted in height, angle, and depth (distance from the passenger) to suit individual passenger preferences.

[0042] The term “seat unit” encompasses the seat and its immediate surroundings in the cabin, including in particular a side console, where passengers can find equipment such as in-flight entertainment controls, power outlets, reading lights, storage for personal belongings, and other items.

[0043] Figures 1 and 2 represent a table assembly 100 according to an embodiment of the invention, equipping a seating unit 200. The seating unit 200 mainly comprises a seat 210 and a console 220 laterally attached to the seat.

[0044] According to a standard level of comfort offered in the upper classes (first class and business class), the seat 210 is generally convertible into a bed and the console 220 includes various amenities for the passenger, these elements however not being the subject of the present invention.

[0045] The table assembly 100 is retractable and has two extreme positions: a fully stored position and a fully deployed position represented respectively in [Fig.1] and in [Fig.2].

[0046] The table assembly 100 includes a tray 10, allowing passengers to eat or use it for other purposes when the table assembly is in the deployed position, and a sliding flap 20 allowing both to fully conceal the tray 10 when the table assembly is in the stored position and to automatically and partially eject said tray as explained later.

[0047] When in its fully stored position, as shown in [Fig.1], the table assembly 100 blends into the shape and design of the console 220 in order to save space and, above all, not to alter the aesthetic appeal of the seating unit 200.

[0048] The sliding flap 20 allows the tray 10 to be retracted into an interior volume of the console 220 and has a geometric shape which locally follows the shape of said console.

[0049] Indeed, the sliding flap 20 has a shell shape whose curves follow the continuity of the respective curves of the console 220. Thus, the sliding flap 20 appears to be an integral part of the console 220 and gives the impression of aesthetic uniformity.

[0050] According to the illustrated embodiment, the flap 20 has an open cylindrical shape with a curved base. This curve coincides with a portion of the contour of the upper surface of the bracket 220 below which the flap 20 is located, so that in a top view, said flap is not visible below the upper surface of the bracket 220.

[0051] According to the same illustrated example, the flap 20 is fixed to a front portion of the console 220, between its lateral face abutting the wall 230, referred to as the rear face, and a central area of ​​its lateral face abutting the seat 210, referred to as the front face. In fact, the flap 20 is mounted on the rear face of the console 220 by a first lateral side 21 and extends to its second lateral side 22 located in a central area of ​​the front face of the console, following the external curve defined by the upper surface of said console. This curve locally has an L-shape with a rounded corner 23 in the illustrated example.

[0052] The sliding flap 20 is thus positioned to be immediately accessible to the passenger when he is properly seated on the seat 210.

[0053] The sliding flap 20 is mounted to slide in the console 220, along a longitudinal direction of the latter, along a slide 30. The stroke of the sliding flap 20 in its translational movement is limited and sufficient for the deployment of the plate 10. This stroke corresponds, at most, to the length of the slide 30.

[0054] Sliding the flap 20 downwards allows the tray 10 to be deployed. The deployment of the tray 10 begins with an automatic ejection of the tray 10 caused by the opening of the flap 20 and continues manually until the fully deployed position as shown in [Fig.2].

[0055] Figure 3 shows the automatic ejection of the tray 10 in several positions. consecutive intermediates.

[0056] In (a), the solid arrow pointing downwards indicates the direction of sliding of the flap 20 to begin the deployment of the tray 10. The sliding takes place along a longitudinal direction of the console 220, materialized by the axis 222. The sliding can be easily operated by the passenger using a footprint 24 allowing the passenger to have a gripping area with their fingers.

[0057] The sliding of the flap 20 continues until it reaches a stable position shown in (b). The plate 10 is thus uncovered but remains in its stored, immobile position.

[0058] The bistable configuration of the valve 20 between the closed position and the open position is ensured by an actuation mechanism which will be described with reference to [Fig.5a].

[0059] An additional downward slide with a smaller amplitude, indicated by the solid arrow in (c), allows an actuating mechanism to be activated which automatically ejects the tray 10 partially out of its storage compartment 50 as shown in (d).

[0060] After the additional sliding of the flap 20 which actuates the ejection of the tray 10, the flap returns to its stable position before the additional sliding, i.e. to the same height as the position shown in (b). Thus, the additional sliding of the ejection of the tray 10 is a monostable sliding around an initial position which is the stable position of the open flap, and allows the ejection of the tray 10 to be triggered by means of a suitable actuation mechanism which will be described later with reference to [Fig. 5b].

[0061] Alternatively, the automatic partial ejection of the tray can be achieved by means of an eject button, instead of the additional sliding of the flap. Such an eject button can be positioned near the tray, preferably under the flap so that it is only accessible when the flap is open. This more effectively prevents any accidental ejection of the tray.

[0062] Fig. 3 thus summarizes the automatic ejection of the tray 10 under the action of the sliding flap 20, said ejection bringing the tray 10 into an intermediate position which offers a surface sufficient to allow the passenger to grasp the tray 10 and to continue the manual deployment until the final position of full deployment.

[0063] Fig. 4 represents the manual deployment of the platform 10 with some consecutive intermediate positions.

[0064] In the illustrated embodiment, the platform 10 is extendable, by being foldable, and for this purpose comprises two articulated parts: a base 11 and an extension 12.

[0065] The passenger begins by pulling the platform 10 towards them, at (a) and (b), until it is in front of them in a usable position at (c). The passenger's action induces a movement composed of translation and rotation of the platform 10, conditioned by a curved support 40 which is mounted to slide along a curved line. In effect, the platform 10 moves from a stored position in which it is substantially parallel to the console 220 to a deployed position in which it is substantially perpendicular to said console.

[0066] Finally, in (d), the passenger deploys the extension 12 of the platform 10 by pivoting and tilting it to the other side of the base 11, around an axis 13 joining the two parts of said platform. The tilting of the extension 12 is indicated by the solid circular arrow.

[0067] Following this deployment of the platform 10, the table assembly 100 arrives in its fully deployed position as shown in [Fig.2].

[0068] Conversely, the arrangement of tray 10 is done by following the inverse movements of figures 3 and 4 in reverse order.

[0069] Indeed, starting from the fully deployed position of [Fig.2], the passenger begins by folding the extension 12 of the platform 10 against the base 11, (d) to (c), then he pushes the folded platform 10 into its housing 50, (b) and (a), to arrive at the configuration (d) of [Fig.3].

[0070] Configuration (d) of [Fig.3] corresponds to the ejected position of the tray 10. In this position, the passenger exerts direct pressure on the tray 10 to insert it completely into the housing 50. The tray 10 retracts and locks as in configuration (b) of [Fig.3].

[0071] Finally, the passenger manually raises the flap 20 to its closed position in [Fig.1].

[0072] Figures 5a and 5b schematically represent, according to a particular embodiment, the actuation mechanism enabling the kinematics of the table assembly 100 to be achieved as described above. Each of the two figures represents a part of this mechanism, to facilitate understanding and avoid a single figure that would be illegible with the entire mechanism represented. Thus, to reconstruct the actuation mechanism in its entirety, it is sufficient to superimpose Figures 5a and 5b.

[0073] In addition, each part of the mechanism shown in one of Figures 5a or 5b performs a specific and well-defined function.

[0074] Fig. 5a represents the part of the mechanism responsible for the bistable position of the sliding valve 20 between the closed position (top) and the open position (bottom, in dashed line).

[0075] The actuation mechanism includes for this purpose a spring-loaded retaining system 61, which holds the valve 20 stably in either the closed or open position. The retaining system 61 is articulated between the rear of the movable valve 20 and a fixed axis 611.

[0076] The actuation mechanism also includes a weight compensator 62 to assist the sliding movement Cl of the valve 20 for better feel when handling said sliding valve, and end-of-stroke dampers 63 with "soft" stops for smooth and clatter-free opening and closing.

[0077] The sliding movement between the two stable positions of the flap 20, materialized by the double arrow Cl, simply allows the storage space of the tray 10 to be opened or closed without ejecting the latter.

[0078] Fig. 5b represents the part of the mechanism responsible for ejecting the tray 10 and locking it in the stored position.

[0079] After the first sliding Cl which allows the valve 20 to move from its closed position to its stable open position, a second sliding C2 downwards allows the plate 10 to be ejected as described above.

[0080] The actuation mechanism includes for this purpose a locking system 64 comprising an actuating lever 641 and a lock 643 articulated end to end by a rod 642. The lever 641 and the lock 643 are also each articulated on a fixed central axis. Thus, when the user applies the additional sliding action C2, the flap 20 presses on the free end of the lever 641, which then pivots about its fixed pivot axis. This movement is then transferred to the lock 643 via the rod 642; said lock also pivots in the opposite direction to release the tray 10, initially held by the free end 644 of the lock 643.

[0081] The actuation mechanism also includes a spring 65 which ejects E the plate 10 when the latter is released from the lock 643.

[0082] When the tray 10 is ejected, the lock 643 remains locked in its open position, shown in dashed line, constraining a return spring 645.

[0083] Conversely, the pressure exerted to return the tray 10 to its storage position causes it to move back until the return spring 645 can push the lock 643 into its closed position to lock the position of the tray 10 again.

[0084] If the additional sliding C2 of the flap is replaced by an ejection button, the latter can be connected to an ejection and locking mechanism similar or identical to that described in [Fig.5b], with a few trivial adaptations.

[0085] The invention as described relates to a dining table integrated into the environment of a passenger seat in an aircraft. This table is designed to offer passengers a stable space for eating, placing drinks, or using electronic devices. The dining table is retractable and has two positions: stored and deployed. In the stored position, it blends into the design of the side console, thus saving space in the cabin and preserving its aesthetic appearance. When deployed, the table offers a folding surface with a base and an extension, suitable for various uses. Deployment of the table is initiated by opening a sliding flap and can be easily performed by the passenger. Once deployed, the table provides a comfortable space for passengers, thus enhancing their in-flight experience.Finally, the table is stored in the reverse order of deployment, offering an aesthetic integration into the passenger seat environment.
