Tray tables associated with passenger seats within a vehicle are sometimes provided for passenger use while reading, eating, drinking or other activities during travel. Tray tables can be attached via a hinge or other attachment to the back of another passenger seat or arm rest. In this manner, a passenger can fold the tray table down when ready to use. However, these tray tables may be unsteady during use and difficult to stow away when not in use. Other tables may be permanently fixed between passenger seats for use by multiple passengers. In these cases, the tables take up valuable space within the passenger seating area causing inconvenience for passengers when the tables are not in use by passengers.
The disclosed examples are described in detail below with reference to the accompanying drawing figures listed below. The following summary is provided to illustrate implementations disclosed herein. It is not meant, however, to limit all examples to any particular configuration or sequence of operations. Nor is it intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter.
Some examples provide a modular tray table apparatus including a tray table carrier unit removably mounted to a console of a seat unit. A tray table support element is coupled to the carrier unit and a tray table. The tray table support element movably supports the tray table along a linear displacement path between a fully retracted configuration and at least one deployed configuration. A rotational displacement mechanism is disposed between the tray table and the tray table support element. The tray table slides along a rotational displacement path defined by at least one rotational guide between a linear configuration of the tray table and a substantially perpendicular configuration of the tray table.
Other examples provide a method for deploying a tray table of a modular tray table apparatus. A decoupling latch associated with the tray table is actuated to disengage a latching device and detach the tray table from the modular tray table apparatus within a console element of associated with a seat unit. The tray table slides along a linear displacement path between a fully retracted configuration of the tray table within the housing and at least one deployed configuration of the tray table outside of the housing. The tray table rotates via a rotational displacement mechanism disposed between the tray table and a tray table support element. The tray table slides along a rotational displacement path defined by at least one rotational guide between a linear configuration of the tray table and a substantially perpendicular configuration of the tray table when in a fully deployed configuration.
Still other examples provide a system for a modular tray table. The system includes a tray table carrier unit removably mounted to a console of a seat unit. A tray table support element is coupled to the carrier unit and a tray table. The tray table support element movably supports the tray table. A linear displacement mechanism is disposed between the tray table and the tray table support element. The tray table slides along a linear displacement path between a fully retracted configuration and at least one deployed configuration. A rotational displacement mechanism is disposed between the tray table and the tray table support element. The tray table slides along a rotational displacement path defined by at least one rotational guide between a linear configuration of the tray table and a substantially perpendicular configuration of the tray table. A latching mechanism is associated with a housing of the modular tray assembly. The latching mechanism holds the tray table within the housing when the tray table is stowed in the retracted configuration.
This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter.
Corresponding reference characters indicate corresponding parts throughout the drawings.
A more detailed understanding can be obtained from the following description, presented by way of example, in conjunction with the accompanying drawings. The entities, connections, arrangements, and the like that are depicted in, and in connection with the various figures, are presented by way of example and not by way of limitation. As such, any and all statements or other indications as to what a particular figure depicts, what a particular element or entity in a particular figure is or has, and any and all similar statements, that can in isolation and out of context be read as absolute and therefore limiting, can only properly be read as being constructively preceded by a clause such as “In at least some examples, . . . ” For brevity and clarity of presentation, this implied leading clause is not repeated ad nauseum.
Referring to the figures, examples of the disclosure enable a modular tray table. In some examples, the modular tray table apparatus easily slides into and out of a housing within a console of the passenger seat unit. A handle is pulled to easily release the tray table from the housing. This provides simple and intuitive handling by a passenger.
In other aspects, an improved console element with such a tray table apparatus may be configured as a pre-assembled module which is releasable mountable to the console element. Thereby, assembly and disassembly of the tray table assembly for maintenance work, repair work replacement/exchange of component parts is greatly simplified.
In still other aspects, each tray table is removably mounted within a housing slot of each seat unit console corresponding to a passenger seat. This provides an improved seat unit comprising a seat and a substantially adjacent console element with a modular tray table apparatus which is easily stowable when unneeded and retractable for use by a passenger seated behind the seat unit for greater convenience and reduced tray table space utilization within the passenger seating area.
In some examples, the modular tray table apparatus enables a simple and intuitive table movement for a passenger. Due to the rotational displacement of the table element during movement of the table support element, the time required for a user to deploy or stow the tray table is reduced. When the table support element moves from the retracted position to the deployed position, movement of the table element from the stowed position to the use position is smoothly carried out.
Referring again to
The seat unit 106 is a passenger seat unit within the vehicle 108. In some examples, the seat unit 106 includes the furniture, structure, fixtures, base and/or other support members associated with a passenger seat 110. The seat unit 106 can include, for example, but without limitation, the seat 110 for a single passenger to sit on, the console 104, a back wall panel, a side wall panel, a privacy door, an access space/path enabling passenger ingress and egress from the seat and/or seating area around the seat, cup holders, a tray table 112, a display screen/video screen, footrest, back rest, head rest, or any other seat-related devices. In this example, the seat unit 106 includes the modular tray table apparatus 100 installed within a slot of the seat unit 10 and the passenger seat 110.
The passenger seat 110 is a seat, chair, or other surface on which a passenger can sit up, recline and/or lay down. The seat 110 can include a base member, a back member, cushion(s) arm rest(s), and/or a head rest. The passenger seat is optionally a static seat, a swivel seat and/or a reclining seat.
The vehicle 108 is a vehicle for transporting one or more users from a first location to a second location. The vehicle 108 can include any type of vehicle, such as, but not limited to, an aircraft, boat, ship, space liner, bus, or any other type of vehicle. In this non-limiting example, the vehicle is an aircraft. An aircraft can include a commercial airplane, a private airplane, a hover craft, a seaplane, or any other type of aircraft.
In some examples, the tray table carrier unit 114 is removably mounted to the console 104 of the seat unit 110. The tray table carrier unit 114 is a base member of the modular tray table apparatus 100 which mounts into a tray mounting device 116. In some examples, the tray mounting device 116 includes a set of one or more rail(s) 118 on which the modular tray table apparatus 100 is attached via a set of fasteners, such as screws, bolts, or other fasteners. In this example, the tray table carrier unit 114 removably mounts onto the rail(s) 118.
In still other examples, the tray mounting device 116 defines a slot 120 or other open space within a portion of the console 104 sized to accommodate a housing of the modular tray table apparatus 100. In some examples, the modular tray table apparatus 100 removably mounts onto the rail(s) 118 within the rectangular or cassette-shaped slot 120 of the tray mounting device 116 within the console 104. The slot 120 in this example is sized to accommodate the exterior dimensions (size and shape) of the modular tray table apparatus 100.
In other examples, a tray table support element 122 coupled to the carrier unit 114 at a first end and coupled to the tray table 112 at a second end of the tray table support element 122. The tray table support element 122 movably supports the tray table 112 as it moves from a retracted configuration 124 to a deployed configuration 126. In some examples, the tray table support element 122 includes one or more telescoping support arm(s) 128 supporting the tray table as the tray table is deployed. In some examples, the tray table is suspended over the lap of a user in the fully deployed position.
The modular tray table apparatus 100 in some examples includes a linear displacement mechanism 130 disposed between an underside (bottom member) of the tray table 112 and the tray table support element 122. The tray table 112 slides along a linear displacement path 132 between the fully retracted configuration 124 when the tray table 112 is stowed within the console 104 and an at least partially deployed configuration 126 when the tray table is deploying out of the tray table housing in the console, such as deployment for use by a passenger.
In some examples, the linear displacement mechanism 130 includes a set of rails associated with the tray support element 122. In other examples, the linear displacement mechanism 130 includes a set of one or more guides and guiding elements for guiding linear movement of the tray table.
In other examples, a rotational displacement mechanism 134 is disposed between an underside (bottom member) of the tray table 112 and the tray table support element 122. The tray table 112 slides along a rotational displacement path 136 having a degree of rotation 138. In some examples, the degree of rotation is a ninety-degree arc of rotation. However, the examples are not limited to a ninety-degree arc of rotation. In other examples, the degree of rotation 138 is a forty-five-degree arc of rotation, a forty-five-degree arc of rotation, or any other suitable degree of rotation.
The rotational displacement path 136 in some examples is defined by at least one rotational guide between a linear configuration of the tray table and a substantially perpendicular configuration of the tray table. The rotational guide is a channel, groove, track, railing, depression, trough, or other guide to receive a corresponding guiding element. In this example, one or more guiding elements on the underside of the tray table slides through the rotational guide(s) to direct the tray table along the rotational displacement path 136 as the tray table is rotated from the linear configuration into a substantially perpendicular configuration for utilization by a passenger.
In some examples, a stowing motion of the tray table support element 122 and a stowing motion of the tray table 112 are coupled in a combined motion or forced motion. For example, initiating stowing of the tray table 112, such as by pushing or pressing against the tray table, may cause the tray table support element 122 to move partially from the deployed configuration 126 in a direction towards the retracted configuration 124. For example, initiating stowing of the tray table support element 122, such as by pushing or pressing against the table support element, may cause the tray table 112 to move partially from the in-use (fully deployed) position in a direction towards the stowed position. In the stowed position, a longitudinal extension axis of the tray table 112 is arranged parallel to a longitudinal extension axis of the tray table support element 122.
In other examples, a movement of the tray table 112 between the stowed position and the in-use position comprises a linear displacement and the rotational displacement relative to the longitudinal extension axis of the tray table support element. The rotational displacement of the tray table, such as a table leaf, with respect to the table support element is carried out about a virtual pivot, such that the tray table 112 avoids undesirable contact with other elements, e.g., other furniture structures, such as, but not limited to, console 104 structures, back shell and seat dividing structures during displacement between the fully deployed (in-use) position and the stowed position. The linear displacement and the rotational displacement are configured such that the tray table carries out a predefined motion along a virtual line about the virtual pivot, whereas the tray table 112 does not protrude the virtual line. Further, it is possible to easily stow the tray table 112 at any point within the linear displacement range.
Common table elements, in other examples, are pivotable about one pivot point provided at a fixed location. The combination of the linear displacement and the rotational displacement allows a smooth and an easy-to-handle adjustment of the tray table 112. Further, the tray table 112 and the table support arm are both dependently or independently enabled to be pushed away for egress from a seat without fully stowing and clearing a table surface.
In another example, the tray table support element 122 includes a rear end coupled to the carrier unit 114 and a front end pointing away from the carrier unit 114. The tray table 112 includes at least first and second lateral sides defining a tabletop between them. In the stowed position of the tray table 112, the first lateral side is positioned in an area of the rear end and the second lateral side is positioned in an area of the front end of the tray table support element 122. In the use (fully deployed) position of the tray table 112, the first lateral side is positioned in the area of the front end and the second lateral side is positioned rotated away from the front end about a predefined angle. For example, when the tray table 112 is positioned in the stowed position, the first lateral side is positioned substantially perpendicular to the longitudinal extension axis of the table support element. When the tray table 112 is positioned in the use position, the first lateral side is positioned substantially parallel to the longitudinal extension axis.
The console 200 may be part of a furniture structure to create privacy for a passenger in a vehicle cabin. For example, the console 200 or any other structural component of a vehicle cabin may provide an open space in which the tray table apparatus is easily insertable and attachable thereto.
The tray table apparatus, in this example, is shown in a mounted and fully stowed state within a triangular-shaped portion of the console 200. However, the console 200 is not limited to the size, shape, dimensions, or design of the console shown in
In some example, the modular tray table apparatus 100 sits within a slot or other tray mounting space associated with the console. In this non-limiting example, the modular tray table apparatus 100 is mounted below a portion 202 of the console 200. The tray table (not shown) is not visible in this example as the tray table is in a fully stowed position within the modular tray table apparatus 100.
In this example, the modular tray table is installed such that the tray table deploys at or near the approximate level of the waist height or chest height of a seated passenger for convenient utilization during eating and/or drinking. However, the examples are not limited to installation of the modular tray table apparatus at the position and/or height shown in
The tray table 502 includes a tray table support element 512 mounted to the carrier unit and which is movable between a retracted position and a deployed position. The tray table support element in this example includes a set of telescoping rails 510. In this example, the telescoping rails 510 are uncovered such that a pass-through space is visible. In other examples, the rails are covered by a cover, such as, but not limited to, the cover 610 in
The tray table is movably supported on the table support element rails 510 between at least a stowed position and a partially deployed position of the tray table support element. In other words, the tray table support element is in a deployed or partially deployed position in which the tray table is outside the tray mounting device slot inside the console. The tray table is arranged in the stowed position (linear orientation).
In this example, the tray table 602 is partially deployed along a linear displacement path. A carrier unit 608 attached to a support arm 606 is mounted to at least a portion of the console. In some examples, the carrier unit 608 is mounted to a housing which is mounted to a tray mounting device on the console, such as, but not limited to, the tray mounting device 116 in
The support arm 606 is a telescoping arm having a cover 610 such that there is no pass-through space between the sides or rails of the telescoping support arm 606. However, in other examples, the support arm may be implemented as a set of one or more rails without the cover 610.
The cover 610 in this example covers the support arm to improve an appearance of the tray table support arm 606 but does not function to provide additional support to the tray table. The tray table is supported by one or more support arms, including the support arm 606. However, in other non-limiting examples, the cover may provide additional support structure and/or stability to the tray table 602.
The tray table 602 in this example is in a linear (stowed) orientation such that the tray is in position or orientation to be returned into the tray table housing or tray table slot of the tray mounting device within the console, if desired by the user. The tray table 602 can be rotated along a rotational displacement path to re-orient the tray table 602 into a substantially perpendicular position for utilization by a passenger during eating, drinking, reading or other tray table use.
In some examples, the support arm(s) extend during linear deployment a distance or length of approximately twenty-four and a half (24.5) inches. However, the examples are not limited to an extension of the tray table of twenty-four and a half inches. In other examples, the tray table is deployed along a linear distance or length of twenty inches, fifteen inches, twenty-five inches or any other suitable distance to enable a user sitting in a corresponding passenger seat to conveniently reach the tray table for utilization during meals, enjoying snacks, and/or other activities.
In some examples, the tray table 802 is configured to carry out a rotational displacement along a rotational displacement path 136 between the stowed position and the in-use position during movement of the tray table support element between the retracted position and the deployed position. The tray table 802 is moved from the in-use (perpendicular orientation) position to the stowed (parallel orientation) position during movement of the tray table support element 806 from the deployed position to the retracted position.
Further, an appearance of a deployment motion from the stowed position to the use position of the tray table 802 during a deployment motion of the tray table support element, such as when the tray table is initially pulled out from the console 808, is improved when the tray table 802 turns with the deployment of the tray table support element 806 towards the seat 810. The console 808 is a furniture piece associated with the seat unit 804, such as, but not limited to, the console 104 in
In this example, the tray table support element 914 is in the deployed position and the tray table 902 is arranged in the in-use position, where the tray table is rotated about a predefined angle. In this example, the predefined angle is ninety degrees (90°) in which the tray table is substantially perpendicular to the tray table support element 914. However, the examples are not limited to a ninety-degree rotation of the tray table. In other examples, the predefined angle is ninety-five degrees, forty-five degrees, or any other predefined degree of rotation to place the tray into position for use by a passenger seated in the seat 906.
The tray table support element is moved back in a direction towards the carrier structure attached to the tray mounting device within a slot of the console 910 to provide egress and ingress space into the seat 906 and/or away from the seat 906.
The tray table support element 914 in this example includes a set of rails 916 without a cover, as well as at least one covered support arm 918. A rotational (curved) guide 920 within the tray table support element 914 guides rotation of the tray table 902 along the arc of rotation from the linear orientation into the substantially perpendicular orientation. A linear guide 922 within the tray table support element 914 guides linear movement of the tray table along a linear displacement path from the fully deployed configuration to the fully retracted configuration.
The tray table support element 1004, in this example, in the deployed position and the tray table 1002 is arranged in the in-use (rotated) position. The tray table support element 1004 includes an upper support arm 1006 connected to the carrier unit (not shown) and the lower support arm 1008. The upper support arm and the lower support arm are adjustable relatively to one another and to the carrier unit.

The linear displacement direction moving away from the console and toward the console 1010 in along the linear displacement path. The console 1010 is a console associated with a seat unit 1012 having a seat 1014, such as, but not limited to, the console 104 in
In this example, the tray table support element 1004 includes an adjustable telescopic mechanism. The upper support arm 1006 and the lower support arm 1008 are adjustable relatively to each other in a manner of a telescopic mechanism, e.g., by a rails, tracks, or any other sliding mechanism.
The tray table 1002, in some examples, has the second lateral side positioned (rotated) away from the front end at about an angle of 90° when the table is in-use by a passenger. In other examples, the tray table 1002 is coupled to the tray table support element 1004 via at least one linear displacement mechanism provided between the tray table 1002 and the table support element 1004. The linear displacement mechanism is configured to guide the tray table 1002 along the longitudinal extension axis of the table support element. The linear displacement mechanism comprises at least a linear guide and a corresponding guiding element movably arranged in the linear guide. The linear guide is provided on either the table support element or the tray table 1002 The guiding element is provided on either the table support element or the tray table 1002.
The support arm 1104 is connected to another support arm 1106. The second support arm is connected to a carrier unit 1108 which is mounted to the console 1110. The console 1110 is a console such as, but not limited to, the console 104 in
The console mounting device 1304 is a device for removably mounting the modular tray table apparatus 100 to the console. In some examples, the console mounting device 1304 includes a set of one or more fasteners 1312 for fastening the modular tray table apparatus 100 to the tray mounting device within a slot or other open space inside the console. In one example, the fastener(s) 1312 are secured through one or more fastener holes or slots in the tray mounting device to removably attach the modular tray table apparatus 100 to the console.
The tray table 1306 is a tray table such as, but not limited to, the tray table 112 in
The linear guide 1320 in some examples is a groove 1322. The groove 1322 is a linear groove, path, channel, indentation, or other channel through which the tab 1318 slides. In other examples, the linear guide 1320 is implemented as a set of rails or support arms, such as the support arm 1324 and/or rail 1326 of the support element 1310. In these examples, the linear guiding element 1314 slides along the support arm or rail 1326 along the linear displacement path.
A rotational guiding element 1316 is an element associated with the tray table 1306. In some examples, the guiding element 1316 is a tab 1328 attached to an underside of the tray table 1306. The tab 1328 can be implemented as a peg, tab, pin, roller, or any other element which fits inside the rotational guiding element 1330 and slides or moves along the rotational displacement path defined by the rotational guiding element 1330. In some examples, the rotational guiding element 1330 is a groove 1322 in the support arm 1324 attached to the underside of the tray table 1306. The groove 1322 is a groove, path, channel, indentation, or other channel through which the tab 1328 slides or moves.
In some examples, the support arm 1324 attaches to another support arm 1325. The support arm 1324 either attaches to another support arm or attaches to the carrier unit 1308. The support arm 1325 is implemented as one or more rails. The one or more rail(s), such as the rail 1327, is optionally covered by a cover member which covers an open space one or more sides of a single rail. The cover optionally covers a pass-through space between two or more rails.
A latch 1332 optionally secures the modular tray table apparatus 100 inside the console when the modular tray table apparatus 100 is in the fully stowed (retracted) configuration. The latch is decoupled or released when a user pulls or otherwise activates a handle 1334 on the modular tray table apparatus 100 to deploy or partially deploy the tray table 1306.
In one example, the tray table 1306 is coupled to the tray table support element 1310 via at least one rotational displacement mechanism provided between the tray table 1306 and the tray table support element 1310.

In other examples, the rotational guide 1330 is provided on the tray table and the rotational guiding element 1316 is provided on the support arm 1324 of the support element. Thus, the rotational guide 1330 is provided either on the tray table support element or the tray table itself. Likewise, the rotational guiding element 1316 is provided either on the table support element 1310 or the tray table 1306.
In other examples, the tray table support element 1310 includes at least a self-stowing mechanism 1336 which is configured to automatically move the tray table 1306 into the stowed (retracted) configuration when the tray table is at least partially moved back from the use position towards the stowed position.
In still other examples, the tray table support element 1310 is movably coupled to the carrier unit 1308 in a linear displaceable manner. The tray table support element 1310 includes an upper support arm 1324 and a lower support arm 1325 which are adjustable relatively to one another and to the carrier structure. For example, the table support element includes an adjustable telescopic mechanism, wherein the lower and upper support arms are adjustable relatively to each other in a manner of a telescopic mechanism.
The modular tray table apparatus 100 in other examples, is configured as a pre-assembled module. The modular tray table apparatus 100 is applicable to any console element, such as a passenger utility element. Further, the modular tray table apparatus 100 is substantially lightweight and comprises a compact built-in design. Moreover, any component of the modular tray table apparatus 100 is exchangeable in an easy manner. The table carrier unit 1308 is implemented in any shape and individually formed to fit to a console element. The tray table 1306 and the table support element 1310 are fully stowable within the housing 1302 such that the tray table and the table support element are protected against external influences, e.g., dust and dirt. Moreover, the appearance of the passenger area and the amount of passenger space available are increased.
The self-stowing mechanism is a mechanism such as, but not limited to, the self-stowing mechanism 1336 in
The tray table 1402 in this example is partially rotated along the rotational displacement path defined by the rotational guide 1412. A rotational guiding element 1414 slides through the rotational guide 1412 during the rotational movement of the tray table.

In some examples, the tray table 1600 includes a top (upper) surface 1602, a right side 1604, a left side 1606, a front side 1608, a rear side 1610 and/or a bottom (underside) surface 1612. The top surface 1602 is the surface utilized by a user when the tray table is in-use. The bottom surface 1612 of the tray table 1600 includes a set of guiding elements 1614, such as a linear 1616 guiding element and/or a rotational 1618 guiding element.
A linear configuration 1620 of the tray table 1600 is a configuration of the tray table in which the table is aligned or oriented (ready-to-be) stowed 1622. In other words, the tray table is substantially parallel 1623 with the support arm(s). In a rotated configuration 1624 the tray table is rotated to a position in which the tray table is ready for use by a passenger or already in-use 1626. In some examples, the tray table is substantially perpendicular 1628 to the support arm(s) while in the fully rotated configuration 1624. In a partially rotated configuration, the tray table is at an angle which is somewhere between the zero degree and ninety-degree orientation.
A linear guide 1708 is provided on the support arm 1706. A linear guiding element 1710 of the tray table is disposed within the linear guide. The linear guiding element 1710 slides along the linear guide 1708 during linear movement of the tray table while the tray table is in a substantially parallel orientation to the support arm. In this example, the guiding element is only partially deployed along the linear displacement path. In this example, the linear guide 1708 is a track. The guiding element 1710 slides along the track during the linear movement.
A rotational guiding element 1712 on the tray table 1702 is disposed within the rotation guide 1714. The rotational guiding element 1712 slides along the rotational guide 1714 during rotational movement of the tray table when it rotates from the substantially parallel orientation to the substantially perpendicular orientation of the tray table. In this example, the tray table is not rotated and the rotational guiding element 1712 is disposed at a beginning point of the rotational guide.
In the example of
The tray table 1802 in this example is configured to carry out at least a rotational displacement and a linear displacement between the stowed position and the in-use position. The tray table 1802 with respect to the table support element 1804 rotates about a virtual pivot 1806, such that the tray table 1802 avoids undesirable contact with other elements, such as other furniture structures. Other furniture structures can include the console structures, back shell and/or seat dividing structures during displacement between the use position and the stowed position or vice versa.
The linear displacement and the rotational displacement are configured such that the tray table 1802 carries out a predefined motion along a virtual line and about the virtual pivot 1806, whereas the tray table 1802 does not protrude the virtual line 1808. The table support element 1804 includes a rear end coupled to the carrier unit and a front end pointing away from the carrier unit. The tray table 1802 includes a first lateral side 1810 and second lateral side 1812 (in view of their locations when in the use position) defining a tabletop between them. In the stowed position of the tray table 1802, the first lateral side 1810 is positioned in an area of the rear end and the second lateral side 1812 is positioned in an area of the front end of the table support element 1804. In the use position of the tray table 1802, the first lateral side 1810 is positioned in the area of the front end and the second lateral side is positioned rotated away from the front end about the predefined angle.
For example, when the tray table element is positioned in the stowed position, the first lateral side 1810 is positioned substantially perpendicular to a longitudinal extension axis of the table support element. When the tray table is positioned in the use (rotated) position, the first lateral side is positioned substantially parallel to the longitudinal extension axis.
In some examples, the tray table apparatus includes a linear displacement mechanism via which the tray table is coupled to the tray table support element. The linear displacement mechanism is configured to guide the tray table along the longitudinal extension axis of the table support element. The linear displacement mechanism, in this example, includes at least a linear guide, such as a linear recess, linear receptacle or linear slot, and a corresponding guiding element, such as a ball, pin, bolt, or wheel, movably arranged in the linear guide. In the shown embodiment, the linear guide 1814 is arranged on or in the table support element and the guiding element is arranged on the tray table.
In other examples, a location of the guiding element is predefined. In particular, the location of the guiding element is fixed. The linear displacement mechanism is configured to displace the first lateral side of the tray table along and above the table support element.
Further, the tray table apparatus in other examples includes a rotational displacement mechanism via which the tray table 1802 is coupled to the table support element. The rotational displacement mechanism includes at least a curved guide 1816, such as a curved recess, a curved slot or a curved whole, and a corresponding guide element, such as a ball, pin, bolt, or wheel, movably arranged in the curved guide. In the shown embodiment, the curved rotational guide 1816 is arranged on or in the table support element and the guiding element is arranged on the tray table or vice versa.
In some examples, the rotational displacement mechanism is configured to guide the tray table 1802 in rotational manner with respect to the table support element. A location of the guiding element is predefined. In particular, the location of the guiding element is fixed. The location of the guiding element is different from the location of the guiding element of the linear displacement mechanism. The curved rotational guide 1816 and the linear guide 1818 may merge in an area. Thereby, producing of the guides, such as recesses, may be simplified in one step, e.g., by milling or any other technique. The rotational displacement mechanism is configured to displace the second lateral side 1812 of the tray table about the predefined angle above the table support element.
However, in other examples, the guide 1904 is disposed within the tray table 1906. The guiding element 1902 in these examples is attached to the support element. The tray table 1906 in this example is a tray table such as, but not limited to, the tray table 112 in
In this example, the console 2104 includes a console base structure 2106 with a front utility structure (not visible) and an open rear structure 2108. The tray table apparatus is mounted to the console base structure within the open rear structure 2108. The console base structure 2106, in this example, is configured substantially box-shaped with an upper wall and lateral walls extending in a downward direction from the upper wall creating the open rear structure. The tray table apparatus is held in position in an area of the upper wall after installation.
In other examples, the open rear structure 2108 includes a footwell space for a passenger seated behind the console base structure. The utility structure includes at least one of a shelf, an armrest, a table, storage space and storage means. The storage means can provide storage space for a remote control, magazines, suitcases, shoes, headphones, or other items belonging to the passenger or airline. Additionally, the utility structure, which is positioned next to a corresponding seat of the seat unit, can comprise service and operational elements, such as switches and HMI-panel to control operable features of the seat and/or a seat unit.
The full linear deployment in this examples approximately twenty-four and a half inches. The full rotational deployment is approximately ninety-degrees to reach full deployment of the tray for use by a user.

The following paragraphs describe further aspects of the disclosure. In some implementations, the paragraphs described below can be further combined in any sub-combination without departing from the scope of the present disclosure.
At least a portion of the functionality of the various elements in
While the aspects of the disclosure have been described in terms of various examples with their associated operations, a person skilled in the art would appreciate that a combination of operations from any number of different examples is also within scope of the aspects of the disclosure.
While the aspects of the disclosure have been described in terms of various examples with their associated operations, a person skilled in the art would appreciate that a combination of operations from any number of different examples is also within scope of the aspects of the disclosure.
The order of execution or performance of the operations in examples of the disclosure illustrated and described herein is not essential, unless otherwise specified. That is, the operations can be performed in any order, unless otherwise specified, and examples of the disclosure can include additional or fewer operations than those disclosed herein. For example, it is contemplated that executing or performing an operation before, contemporaneously with, or after another operation is within the scope of aspects of the disclosure.
The indefinite articles “a” and “an,” as used in the specification and in the claims, unless clearly indicated to the contrary, should be understood to mean “at least one.” The phrase “and/or,” as used in the specification and in the claims, should be understood to mean “either or both” of the elements so conjoined, i.e., elements that are conjunctively present in some cases and disjunctively present in other cases. Multiple elements listed with “and/or” should be construed in the same fashion, i.e., “one or more” of the elements so conjoined. Other elements may optionally be present other than the elements specifically identified by the “and/or” clause, whether related or unrelated to those elements specifically identified. Thus, as a non-limiting example, a reference to “A and/or B”, when used in conjunction with open-ended language such as “comprising” can refer, in one embodiment, to A only (optionally including elements other than B); in another embodiment, to B only (optionally including elements other than A); in yet another embodiment, to both A and B (optionally including other elements); etc.
As used in the specification and in the claims, “or” should be understood to have the same meaning as “and/or” as defined above. For example, when separating items in a list, “or” or “and/or” shall be interpreted as being inclusive, i.e., the inclusion of at least one, but also including more than one, of a number or list of elements, and, optionally, additional unlisted items. Only terms clearly indicated to the contrary, such as “only one of or “exactly one of,” or, when used in the claims, “consisting of,” will refer to the inclusion of exactly one element of a number or list of elements. In general, the term “or” as used shall only be interpreted as indicating exclusive alternatives (i.e., “one or the other but not both”) when preceded by terms of exclusivity, such as “either”, “one of”, “only one of,” or “exactly one of” “Consisting essentially of,” when used in the claims, shall have its ordinary meaning as used in the field of patent law.
As used in the specification and in the claims, the phrase “at least one,” in reference to a list of one or more elements, should be understood to mean at least one element selected from any one or more of the elements in the list of elements, but not necessarily including at least one of each and every element specifically listed within the list of elements and not excluding any combinations of elements in the list of elements. This definition also allows that elements may optionally be present other than the elements specifically identified within the list of elements to which the phrase “at least one” refers, whether related or unrelated to those elements specifically identified. Thus, as a non-limiting example, “at least one of A and B” (or, equivalently, “at least one of A or B,” or, equivalently “at least one of A and/or B”) can refer, in one embodiment, to at least one, optionally including more than one, A, with no B present (and optionally including elements other than B); in another embodiment, to at least one, optionally including more than one, B, with no A present (and optionally including elements other than A); in yet another embodiment, to at least one, optionally including more than one, A, and at least one, optionally including more than one, B (and optionally including other elements); etc.
The use of “including,” “comprising,” “having,” “containing,” “involving,” and variations thereof, is meant to encompass the items listed thereafter and additional items.
Use of ordinal terms such as “first,” “second,” “third,” etc., in the claims to modify a claim element does not by itself connote any priority, precedence, or order of one claim element over another or the temporal order in which acts of a method are performed. Ordinal terms are used merely as labels to distinguish one claim element having a certain name from another element having a same name (but for use of the ordinal term), to distinguish the claim elements.
Having described aspects of the disclosure in detail, it will be apparent that modifications and variations are possible without departing from the scope of aspects of the disclosure as defined in the appended claims. As various changes could be made in the above constructions, products, and methods without departing from the scope of aspects of the disclosure, it is intended that all matter contained in the above description and shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
