[0001] The subject disclosure relates to carrier systems, and more particularly, to a vehicle tray system.BACKGROUND

[0002] In the aircraft industry, seats are commonly equipped with a sliding tray table that is attached to a rear of a seat so that a passenger sitting behind the seat has a platform from which snacks / b everages, electronic devices, or other articles can be supported during flight.

[0003] FIGs. 1-4 show examples of conventional tray table assemblies. FIG. 1 shows an example of a prior art passenger seat 10 used in aircraft. The passenger seat 10 includes a base frame 11, a seat back 12 with a seat back aft surface of 13 mounted to the base frame 11, and a conventional tray table 17 mounted to the base frame 11 via tray table arms 9. The tray table 17 comprises a shroud 19. The shroud 19 slides b ackwar d / forward or up / down on a pair of sliders 14 that are typically spaced from each other and coupled to the left and right edges of the shroud 19. The sliders 14 may be connected to a tray table torque tube 15 which provides structural rigidity and stiffness to the tray table 17 assembly. The torque tube 15 may be connected between a pair of rotatable hinges 18 coupled to the seat frame arms 9. The tray table 17 is commonly not connected directly to the seat back aft surface of 13 and is instead connected to the base frame 11 because the base frame 11 is typically fixed in place and does not move whereas the seat back 12 and seat back aft surface of 13 may move when reclined. It is also known to include a shallow cup holder 16 which may be a depression set into the top surface of the shroud 19.SUMMARY

[0073] The detailed description set forth below is intended as a description of various configurations of the subject technology and is not intended to represent the only configurations in which the subject technology may be practiced. The appended drawingsDOCKET NO. NEX2-PAU01P-U are incorporated herein and constitute a part of the detailed description. The detailed description includes specific details for the purpose of providing a thorough understanding of the subject technology. However, it will be apparent to those skilled in the art that the subject technology may be practiced without these specific details. Like or similar components are labeled with identical element numbers for ease of understanding.

[0074] Overview

[0075] In general, and referring to the figures, embodiments provide a tray table assembly including multi-functional tray table 130 (and for the sake of simplicity, multifunctional tray table 130 will be referred to as “tray table 130”) with a sliding mechanism through elimination of dual sliders onto which the tray table shroud 132 slides back and forth. Instead, an embodiment of the subject apparatus utilizes a multi-functional torque tube integrated mono-slider support assembly 150 (referred to sometimes as the “monoslider 150” for sake of brevity), which not only enhances the sliding quality, but also utilizes the spaces surrounding the torque tube 155, that is not typically used in conventional tray systems. Ergonomic features may be integrated into the mono-slider 150 including for example, a movable wall 145 and included a cup holder 158, without introducing new cost and weight penalties. While the description is provided using an airplane seat for illustration, it will be understood that the vehicle tray of the subject disclosure may be adapted to or mounted onto the seat types of other vehicles and is not necessarily restricted to airplanes.

[0076] Definitions

[0077] Integrated, as used herein refers to elements that are combined together as a whole and inseparable unit.

[0078] Preferred Embodiments

[0079] Referring now to FIGs. 5- 7, 7A, 7B, 7C, 7D, 8-10 and 17, a seat system 100 is shown according to an embodiment. The seat system 100 may include a backrest 110. The seat system 100 includes a seat pan 112 mounted onto a seat frame assembly 115 that is configured to mount to a vehicle’s internal chassis or floor. Embodiments of the seat system 100 generally include one or more leg frames 113 and arm rests 114. As points of reference, the seat pan 112 and arm rests 114 generally face forward relative to the back rest 110 that is mounted to the seat frame assembly 115. Some embodiments include a hub or storage module 120 mounted to the backrest rear surface 124. The backrest 110DOCKET NO. NEX2-PAU01P-U may include rear facing sidewalls 122 on the right and left sides that project rearward defining an empty space on the rear of the backrest 110. The hub or storage module 120 may be set into the empty space between the sidewalls 122. The empty space under the hub or storage module 120 may be sized to store the tray table 130 when stowed into an upright position (i.e., when not in use). The seat assembly frame 115 may include a pair of arms 108 that extend rearward. The tray table 130 is generally coupled to the arms 108 via pivot hinges 160 that are configured to rotate the tray table 130 up and down form stowed to deployed positions. The arms 108 connect the tray table 130 to the base frame 115. A top view of the system 100 shown in FIG. 10 can be seen in FIG. 17. In FIG 17. The seat back 110 is removed from view in order provide better visibility of the tray table 130.

[0080] An embodiment of the tray table 130 is shown that includes a shroud 132. The tray table 130 is generally configured to telescope back and forth along the mono-slider 150. When the tray table 130 is slid rearward, the back edge 129 of the shroud 132 may abut against the torque tube 155. The shroud 132 and its variations may be a single shell or may be a dual shell structure with two halves hinged together. Referring temporarily to FIGs. 34A and 34B along with FIGs. 5-7 and 8-10, the shroud 132 may be hollow and include a top shell 134 coupled to a bottom shell 138. The top shell 134 and bottom shell 138 may encase a centralized, hollow compartment 131 (See FIG. 34B) that may comprise a top shell 133 coupled to a bottom shell 137. The centralized compartment 131 may be configured to receive the mono-slider support assembly 150 as the tray table shroud 132 is slid toward the backrest rear surface 124. FIG. 25 shows the compartment 131 exploded from the interior of the shroud 132. The corners of respective shells 133, 134, 137, and 138 may be rounded. Some embodiments of the tray table shroud 132 include a cup holder depression 135 positioned on the top surface of the top shell 134.

[0081] The mono-slider 150 may include a single, thin walled profile rectangular post 154 integrated as a one-piece element with the torque tube 155. This means that as the torque tube 155 rotates into stowed and deployed positions for the tray table 130, the mono-slider 150 and the tray table shroud 132 move together as one unit. For example, the torque tube 155 may be connected between pivot hinges 160 that are configured to allow the torque tube 155 to rotate so that the tray table 130 may be moved from an upright storage position to a horizontal, use position. A first end of the post 154 may be centralized with the shroud 132 while the second opposite end of the post 154 may beDOCKET NO. NEX2-PAU01P-U connected to a central point on the torque tube 155 that is half-way between the pivot hinges 160. As such, the post 154 projects perpendicularly from the torque tube 155. Embodiments of the torque tube 155 are shown in either rectangular or circular form factor throughout the embodiments, however, it will be understood that the shape of the torque tube 155 does not depart from the scope of protection embodied therein.

[0082] As shown in FIG. 7, the tray table assembly 130 is depicted illustrating a few different relative dimensions. Dimension ST represents the depth of sidewalls 122. Dimension TT represents the thickness of the shroud 132. Dimension GAP represents the distance between the backrest rear surface 124 and the torque tube 155. Dimension SL is the length of sliding available along the mono-slider 150 for the shroud 132.

[0083] As may be appreciated, the structure of the proposed embodiments provides additional clearance in areas that were previously restricted from utility by conventional tray systems. For example, the size difference between sidewalls 122 depth (ST) and the thickness TT of the table shroud 132 leaves a separation that extends between the backrest rear surface 124 and the shroud 134 when the table 130 is in stowed (non-usable) position. This separation distance may never reach zero due to the size difference between TT and ST. This separation distance is useful to provide additional room to make a shroud extender (discussed for example, in FIGs. 42A, 42B, and 42C and labeled as shroud extenders 832A, 832B, and 832C) taller. To quantify this, the thickness TT of the tray table 130 normally does not extend beyond 1 inch (for aesthetic and weight saving purposes) and the empty space of dimension ST is normally between 1.5” and 2” in size (for structural integrity, stiffness purposes seat back is a highly structural part). This allows a shroud extender to be as tall as between 0.5” and 1” if needed.

[0084] As mentioned previously, some embodiments of the mono-slider 150 include a circular wall 158 that defines an opening that may extend from a top surface through the bottom surface of the mono-slider 150. The diameter of the wall 158 may be sized to hold objects such as cups so that the wall 158 may be interchangeably referred to as the cup holder 158. As shown in FIGs. 5-7 and 8-10, a section of the arc for the cup holder 158 may be positioned inside the length of the torque tube 155. While the cup holder 158 is shown on one end of the mono-slider 150, other embodiments may position the cup holder 158 anywhere along the length of the mono-slider 150 body.

[0085] Some embodiments of the mono-slider 150 include a manually movable wall 145 configured to support an article 140 such as a personal electronic device (PED) intoDOCKET NO. NEX2-PAU01P-U a position where the display faces up toward the user. For example, as shown in FIG. 6, when the article 140 is a PED, the PED may be supported by the movable wall 145 so that the front face of the PED is tilted to face upward at a slight angle that is obtuse relative to the top surface of the tray table 130 and acute relative to the top surface of the monoslider 150.

[0086] FIGs. 6-7 and 8-10 depict the tray table 130 in a fully extended position for use with the movable wall 145 is first being shown in a fully upright and deployed position for use as a support for holding an article 140 such as an electronic device (for example, a smart phone, computing tablet, pocket gaming system, etc.). FIGs. 6-7, 7A, 7B, 7C, 7D, and 8-10 depict a sequence of positions of the movable wall 145 changing from fully upright to being stowed into the compartment 156 within the mono-slider post 150.

[0087] In FIG. 6, the tray table 130 is shown close-up, deployed and extended along the mono-slider 150. The article 140 is shown in a position of use with its supporting element the movable wall 145 set upright. FIG. 7 is an isometric view of the multi-functional tray table 130 deployed and slid open into an operational position. The relationship between the backrest rear surface 124, shroud 132 rear edge 129, mono-slider 150, pivot hinges 160, finite sliding length, cup holder 158, movable wall 145, gap between torque tube 155 and the back rest rear surface 124, can be seen. In FIG. 7, the position of movable wall 145 is shown in a partially or intermediate deployed position.

[0088] As shown in FIGs. 7A, 7B, 7C, and 7D the movable wall 145 may be moved from a fully collapsed position so that the movable wall 145 lies flat inside compartment 156 to a fully upright and / or tilted position to support the article 140. FIG. 7A shows the movable wall 145 stowed inside a space within the shroud 132. When stored in the compartment, a front face 146 lays flat down against the floor of compartment 156. The rear face 148 is exposed and may lay flush with the top surface of the post 154 so that there is clearance between the rear face 148 and a stop or detent 139 within the empty space of the shroud interior. When pulled from inside the shroud 132, the movable wall 145 may be configured to rotate from one of its edges to provide the angle of support for the article 140. When the lip 151 of the post 154 contacts the stop 139, the movable wall 145 may have clearance sufficient to be rotated upward into an operable position as shown in FIG. 7B while providing space for the article 140 to rest against both the front face 146 and the top surface of the post 154 that is located just before or against the rear edge 129 of the shroud 132. In the example shown, the rear edge 128 of movable wall 145 rotatesDOCKET NO. NEX2-PAU01P-U around a pivot hinge 149. When rotated up into an operational position, the rear edge 128 of movable wall 145 turns until the rear face 148 may be up against a stop wall 147 on the rear side of the compartment 156. The movable wall 145 may be further configured so that the angle of tilt during support is adjustable to the preference of the user (for example, perpendicular to the top surface of the mono-slider 150) so that shorter passengers are provided a more comfortable viewing angle. In some embodiments, the movable wall 145 may be configured to rotate beyond a fully vertical orientation, that is obtuse from its fully stowed position so that the article 140 can rest at an obtuse angle from the top surface of the mono-tube slider 150. In such configurations, there may be additional clearance provided between the rear edge 128 and the rear face 148. When not in use, as shown in FIG. 7C, the movable wall 145 may be rotated downward into the compartment 156 in the body of the post 154 that is configured to stow the movable wall 145 in a flat state. As shown in FIG. 7D, the movable wall 145 is configured to lay flat into the profile (thickness) of the post 154 when stowed so that the shroud 132 conveniently slides over the mono-slider 150 without obstruction by the movable wall 145.

[0089] FIG. 8 shows the tray table 130 similarly to what is shown in FIG. 7 except that the movable wall 145 is rotated into a nearly fully vertical position from its storage slot. While Figure 14 is showing a partially open movable wall 145A, in some embodiments, the movable wall 145 A may be configured to rotate beyond a fully vertical orientation, that is obtuse from its fully stowed position so that the article 140 can rest at an obtuse angle from the top surface of the mono-tube slider 150 (as can also be seen in FIG. 5) .

[0090] FIG. 9 is similar to FIG. 8, except that the movable wall 145 is folded almost all the way down toward the storage compartment 156, about to be stowed or deployed, into the storage compartment 156 within mono-slider 150, where its rotation angle is reduced compared to its rotation in FIG. 8.

[0091] FIG. 10 shows the movable wall 145 rotated into a fully stowed and closed position in the mono-slider 150. The movable wall 145 top surface 148 is flush with the mono-slider 150 top surface.

[0092] Shroud Structure

[0093] FIGs. 11-12 show a different embodiment of a tray table 230 that is similar to tray table 130 except that the shroud 232 includes indents 236 at the forward comers of shroud 232. The indents 236 may be configured to receive the pivot joints 160 so that theDOCKET NO. NEX2-PAU01P-U leading edge of the shroud 232 is positioned farther forward and closer to the backrest rear surface 124. The top shell 234, bottom shell 238 and depression 235 are similar to the top shell 134, bottom shell 138 and depression 135. In FIG. 12 the interior of the shroud 232 is shown. The post 154 is shown housed within the confines of compartment 131. The compartment 131 may be present in any of the embodiments of the tray table (130, 230, etc.).

[0094] Self-Stowing Support Wall for Articles

[0095] Referring now to FIGs. 13, 14. 14A, 14B, 14C, 14D, 15, 16, 28, 29, and 30 the self-stowing wall 145 A may be configured to self-stow into the storage compartment 156 and self-deploy via a spring loaded Hinge 149 A. FIG. 14A shows the self-stowing movable wall 145A housed within the shroud 132 interior. In the example shown, the spring loaded hinge 149A is located proximate the forward edge 127A of the movable wall 145 A. The spring loaded hinge 149 A may be pre-configured with tension so that as the rear edge 128A of the movable wall 145A clears the rear edge 129 of the shroud 132, the movable wall 145 A will automatically deploy and rotate upward until the top surface of the movable wall 145 A engages the front edge of the storage compartment 156 (for example, as shown in FIG. 14B). The article 140 may be rested upon the rear edge of the movable wall 145A and the rear edge of the shroud 132 when the movable wall 145A is deployed into an operable position, as shown in FIG. 14C, when the article 140 is removed from use and the table tray 130 is being slid forward, the top surface of the movable wall 145A engages the rear edge of the shroud 132 pushing the movable wall 145A to rotate around the spring loaded hinge 149A. The further the table shroud 132 is moved toward the seat back 110 (not shown in these figures), the farther down into the storage compartment 156 the movable wall 145 A moves until the movable wall 145 A is flat and has clearance to slide under the stop 139, into the interior of the shroud 132.

[0096] In an alternative but related embodiment, the self-stowing movable wall 145 A may be configured to self-stow within the slider post 154 compartment 156 and may be deployed through manual actuation by the user. In this configuration, the deployed position of the movable wall 145A is maintained by a friction hinge, which replaces the spring-loaded hinge 149A. The use of the friction hinge enables adjustable viewing angles of the movable wall 145 A and permits the user to manually stow the movable wall 145 A while preserving the self-stowing functionality of the assembly.DOCKET NO. NEX2-PAU01P-U

[0097] Mechanically, the friction hinge provides sufficient rotational resistance through internal frictional torque to hold the movable wall at various deployed angles under weight of the article 140. The spring-loaded hinge 149A, by contrast, utilizes a preloaded torsion or extension spring to counterbalance the gravitational force exerted by the article 140, ensuring that the movable wall 145 A remains in the deployed position unless actively stowed by the user or the rear edge of the shroud 129 while the shroud 132 slid closed.

[0098] Size Advantages Provided by the Mono-Slider

[0099] The top surface of the various shroud embodiments is used for passengers to place their food and beverages during mealtimes. The shroud 132, 232, etc. is designed to accommodate the standard meal trays used by airlines, along with space for drinks, making it easier for passengers to enjoy their meals comfortably, even in the confined space of an aircraft cabin. For passengers looking to work during their flight, the tray table 130 and its various embodiments shroud acts as a makeshift desk. It can support laptops, tablets, documents, and other work-related items, enabling passengers to continue their business activities, write, or engage in other tasks that require a flat surface. In the conventional tray table, due to the limited space, passengers choose between holding personal electronic devices, such as tablets or e-readers, allowing passengers to watch movies, read, or play games in a hands-free manner or use the top surface of the shroud for other activities. The size of the tray table and the tray table shroud of conventional tray table sizes in aircraft seats is indeed limited, which inherently restricts the quantity and size of items that can be placed on it. This means that passengers may need to prioritize essential items, such as a small laptop, a single meal tray, or a beverage, when utilizing the traditional tray table and not be able do all at the same time.

[0100] In the subject disclosure, the mono-slider 150 that includes the movable wall 145 (or movable wall 145 A) and cup holder 158, is configured to allow the shroud 132 to have a larger usable surface area for other activities. The outer shape of the tray table shroud 132 is according to the configuration of the seats and this shape is often rectangular or square with indentations on the top surface or bottom surface of the shroud (see for example, FIG. 14) for aesthetic and / or living space purposes.

[0101] Sliding Action

[0102] Referring now to FIGs. 11-13, 16-18, 21, and 22, the sliding action of the shroud (132 or 232) over the post 154 of mono-slider 150 can be seen in detail. FIG. 11 showsDOCKET NO. NEX2-PAU01P-U the tray table 230 deployed but in a slid forward, retracted position. With the movable wall 145 fully stowed, the shroud 232 is configured to slide over the length of the post 154. As shown in FIG. 12, the shroud 232 structure is depicted transparent to show how that the shroud 232 may be hollow or have a channel, (for example, the compartment 131) therein to receive the post 154, movable wall 145, and cup holder 158 when positioned inside of the shroud 232 as the tray table 230 is moved into a retracted state.

[0103] Referring now to FIGs. 34A, 34B, 35 A, and 35B, details of the shroud 132 and compartment 131 are shown according to embodiments. FIG. 34A and FIG. 34B show a cross sectional views of the shroud 132 and compartment 131, both of which may use C- shaped or U-shaped shells 133, 134, 137, and 138 for ease of assembly purposes. FIGs. 35 A and 35B depict the internal materials and design used in shroud 132. FIG. 35B is showing the side view but the internal material and design used in compartment 131. As shown in FIG. 35B, the post 154 may include a lip 151 that engages a detent 139 on the front interior edge of the compartment 131 which prevents the post 154 from falling out of the compartment 131.

[0104] Shroud Extension

[0105] Referring now to FIGs. 26, 42A, 42B, and 42C, different embodiments of a shroud extender are shown. In these embodiments, the shroud may include different versions of a shroud extender piece that may be used to support the article 140 in place when rested against the movable wall 145 or 145A. In FIG. 26, a shroud 430 is shown similar to the shrouds 130 and 230, except that it includes a shroud extender 433 that is a flange projecting rearward from rear edge 129 of the top surface of the shroud top shell 434. As can be seen, the bottom edge of the article 140 is prevented from sliding further toward the user because the shroud extender 433 prevents the article 140 from sliding forward. Similarly, in FIG. 42A, a shroud 830A is similar to the shroud 430, except the shroud extender 832A is a wall that rises above a top surface of the shroud 830A preventing the bottom of the article 140 from sliding forward. The shroud 830B in FIG. 42B is similar to the shroud 830A except that the shroud extender 832B is a wall that rises forward in a slight angle from the shroud rear edge 129. When the shroud extender 832B, which supports the article 140, is positioned at an obtuse angle (i.e., greater than 90°) relative to the top surface of the shroud 830B, the bottom edge of the article 140 naturally settles into the rear corner or lip of the support, as shown in Figure 42B. As a result, any forward-leaning torque generated by the article 140 is redirected downward rather thanDOCKET NO. NEX2-PAU01P-U upward, due to the angular geometry. This orientation creates a passive mechanical stop that prevents the article 140 from rotating upward or tipping forward.

[0106] In contrast, if the shroud extender 832B were positioned at an acute angle (i.e., less than 90°), the article 140 would function as a longer lever arm, thereby increasing the potential for tipping and upward rotation. At an obtuse angle, however, the effective moment arm for such tipping is reduced, significantly diminishing any rotational advantage. This stabilizing configuration makes upward rotation of the article 140 effectively impossible without the application of excessive force that would exceed the structural limits of the extender 832B However, such failure is unlikely, as the shroud extender 832B may be qualified to withstand expected service loads. Figure 42C is showing a shroud 830C that is similar to the shrouds 830A and 830B except that the shroud extender 832C is a rotatable wall that includes a spring loaded hinge 833 that can provide spring force to retain the article 140. Aside from holding the article 140 into place on the movable wall 145, the shroud extenders extend the max surface of the shroud as it extends above the surface of the torque tube 155. In addition, the shroud extenders hide the torque tube 155 when the tray table is closed, providing some aesthetic benefits. As an impediment to movement of articles 140, the shroud extenders firmly secure the bottom of the articles 140 and protect them from falling down, especially for larger size PEDs, which due to higher weight tend to rotate against the movable wall 145, and fall off, especially during flight turbulences. The shroud extenders may be part of the shroud or be made separately as an add-on to shrouds. The shroud extenders may contain high friction materials to help with article retention. Further, in some embodiments the shroud extender may be used by the passengers to adjust the viewing angle of a PED supported by the movable wall 145.

[0107] The rear edge 129 of shroud 132 which may have no extender, may be used to hold an article 140 in place in the absence of an extender. In addition, the shroud rear edge 129 may be configured to help self-stow the movable wall 145 A.

[0108] Personal Electronic Device Holder and Cup Holder Embodiments

[0109] FIGs. 13-16 show an embodiment of the tray table 130 similar to the embodiment shown in FIGs. 5-11, but instead this version of tray table 130 utilizes the self-stowed version of the movable wall 145A. FIG. 13 shows an isometric view of the tray table 130. The tray table 130 is deployed and slid open and the movable wall 145A is in a deployed position supporting the article 140. FIG. 15 is similar to FIG. 14, withDOCKET NO. NEX2-PAU01P-U exception that the article 140 has been removed and the shroud 132 is about to slide forward into a retracted positioned. The shroud rear edge 129 has just begun moving closer to the seat back, and as consequence of this shroud motion, the movable wall 145 A is pushed down into the compartment 156 (FIG. 7), in a self-stowing action. FIG. 16 shows an isometric view of the tray table 130 in FIG. 15, except that the shroud 132 has almost completely enveloped the movable all 145A. This figure also shows the relationship of the shroud 132 to the cup holder 158 and top surface of the mono-slider post 154 which may also be enveloped once the shroud 132 is in a fully retracted state. Because the shroud 132 is shown transparent, the rear surface of the movable wall 145A is visible when being completely stowed.

[0110] FIG. 18 shows the tray table 130 connected to an embodiment of a mono-slider 250. The mono-slider 250 is similar to the mono-slider 150 except that the torque tube 255 may be round and similar to conventional torque tubes. This picture is made to provide more context regarding one major disadvantage of the torque tube of a tradition tray table by overlaying it at the same location as the torque tube function of mono-slider 150. The relationship between components that would be present in the mono-slider 150 to the conventional torque tube represented by torque tube 255 here, proves a major advantage of the mono-slider 150. The mono-slider 150 provides more space for the cup holder 158 (represented by cup holder 250 here), which would not have been obvious by simply connecting the post 154 to the conventional torque tube 255. The torque tube 255 position clearly overlaps the cup holder 250 pass-through circle hole. As may be appreciated, using a rounded torque tube 255 may not provide sufficient integrity if the tube body has a section removed to accommodate a cup holder 158 that occupies part of the same volume as the rounded torque tube. The principle at play here is the stress concentration and the role of edge margin. When the torque tube is manufactured separately from mono-sliders, introducing new features at their interface of the two parts becomes impractical, as the resulting material discontinuity creates stress concentrations (leading to cracking under loads, fatigue failure and reduction of load bearing capacity) and potential many structural failure points. This is why per edge distance rules, holes and other design features (screws, threaded sections) are typically positioned away from the edges of parts (i.e. a circular threaded hole for screws are positioned 1.5-2 times the size of hole diameter away from the edge), to avoid stress concentrations. In this context, the interface between the torque tube and mono-slider parts effectively acts as an edge orDOCKET NO. NEX2-PAU01P-U discontinuity. As a result, introducing features (e.g., a cup holder or PED holder) near or at this interface is not conventionally practiced and not made that way. By comparison, the one-piece design of mono-slider 150 eliminates this interface, allowing for the integration of features within the formerly unusable space, without compromising structural integrity.

[0111] FIGs. 19-22 shows the passenger seat 100, with tray table 130 in various positions of being rotated from a retracted, stowed state (fully upright) to a lowered and extended state ready for use.

[0112] FIG. 23 shows another embodiment of the movable wall 345 on a post 354. The movable wall 345 includes a wall portion 343 configured to telescope from a base wall portion 347. The wall portion 343 telescopes from a default height to a taller height that would allow the movable wall 345 to hold larger articles 140 such as large PED devices.

[0113] FIG. 24 shows another embodiment of a mono-slider 450 with a torque tube 455 and a post 454 that is similar to the post 154 except that a movable wall 445 is configured differently than the movable wall 145. The movable wall 445 includes an upper wall portion 443 connected to a lower wall portion 447 via a hinge 449 so that the movable wall 445 is configured to bi-fold. The upper wall portion 443 folds over the hinge 449 on the lower wall portion 447. When folded, the movable wall 445 may be used with lower profile PED devices. In addition, the movable wall 445 may need to be folded over when stowed in the post 454 to allow passage of the shroud 132. In some embodiments, the movable wall 445 may be configured to self-stow similar to the movable wall 145 A.

[0114] FIG. 25 shows the tray table 130 assembly in exploded form. In this view the ends of the torque tube 155 are exploded from round pegs 162 on the pivot hinges 160 that allow the torque tube 155 to rotate. The pivot hinges 160 may be coupled to frame arms 108 that connect to the rest of the seat frame. Also visible in this view are pivot pins 149 on the rear edge of the movable wall 145. The movable wall 145 may rotate about the pivot pins 149 that are set into receptacles 159 within compartment 156 (See FIG. 36).

[0115] FIG. 27 depicts examples of conventional cup holders on vehicle seating systems and shows how they collect dirt, food and drink debris within their joints and gaps. As will be appreciated, the cup holder 158 (seen for example, in FIGs. 6-18) may be a hole positioned in the body of the post 154 whose placement avoids areas where food and junk may collect.DOCKET NO. NEX2-PAU01P-U

[0116] FIGs. 28-30 shows the tray table 130 with a mono-slider 550 according to a different embodiment. The mono-slider 550 includes a cup holder 558. The cup holder 558 may be a ring coupled to the torque tube 555 by connector. The cup holder 558 may stow inside the body of post 554 and project rearward of the torque tube 555 when in the open position for use. The rear side of the torque tube 555 may include a slot 559 that extends into the body of the post 554, which can be seen in FIG. 30. FIG. 29 depicts the cup holder 558 in an intermediate position between being stowed and open.

[0117] FIGs. 31-33 show the tray table 130 including a different embodiment of a cup holder 658. The tray table 130 is folded up in the stowed state. In these views, the cup holder 658 can be seen projecting from the rear (now bottom) edge of the torque tube 655. The torque tube 655 may include a rotatable hinge 657 that connects the cup holder 658 to the torque tube 655. As can also be seen, the cup holder 658 may be configured to pivot and rotate about the torque tube 655 so that even though the shroud 130 is folded up, the cup holder 658 sticks out available for use to carry an object.

[0118] In FIG. 36, additional details of the mono-slider 150 can be seen. For example, the lip 151 on the proximal end of the post 154 can be seen, which has been previously obstructed from view by virtue of being covered by the shroud 132. In addition, the pivot pins 149 that are set into receptacles 159 within compartment 156 are enlarged for view so that it is understood how the movable wall 145 may rotate up and down from the compartment 156.

[0119] FIG. 37 shows another embodiment of a slider 152. In this embodiment, in comparison to the embodiment shown in FIG. 36, the post 154 and the torque tube 255 are two separate parts that are fixed together. Notice that in FIG. 37, the cup holder 158 is moved forward and closer to both the shroud 132 and the movable wall 145. As consequence there is less room left for the movable wall 145. The post 154 is made longer than the preferred embodiment, to allow the same functions for the preferred tray table 130. The negative consequence of a longer post 154 is weight increase and poor perceived quality (longer sliders or arms make the table wobble more). In addition, having two separate components (post 154 and torque tube 255) introduces material discontinuity which compromises structural integrity. To compensate for this inherent weakness, additional parts, joints, material or reinforcement is typically required, further increasing the overall weight. This added mass is necessary to meet the stringent abuse and cyclic load requirements for certification in aircraft seating applications. This shows oneDOCKET NO. NEX2-PAU01P-U advantage of the torque tube 155, where additional clearance between the cup holder 158 and the torque tube 155 is possible without losing integrity of the structure.

[0120] Referring now to FIGs. 38-40, another embodiment of a mono-slider 750 is shown. In the mono-slider 750, the post 754 may be modified so that the bottom surface is removed and side rails 752 are included to slide into the interior of the tray table 130. The torque tube 755 may be modified so that the ends include right angle flanges 757. The flanges 757 connect with pivot hinges 760 that are connected to seat frame arms 764. This embodiment shows an example of how there are many ways the pivot hinge elements may be configured to support the tray table 130. FIGs. 39 and 40 show a more detailed view of the pivot hinges 760, which may include a guide pin 762 that may travel within an arm groove 763. The arm groove 763 is configured to guide rotation of the torque tube 755 with help of the guide pin 762. The groove 763 not only guides the guide pin 762, but is also configured to stop the guide pin 762 from exceeding a range of motion as well. It is at this stop position that the tray table 130 as well as the mono-slider 150 become horizontal (with reference to the floor of the aircraft and / or other vehicles) and usable by the passengers.

[0121] FIGs. 41 A, 41B, and 41C show another embodiment of a mono-slider 850 which includes a self-stowing movable wall 845A similar to movable wall 145A. In this embodiment, the top edge of movable wall 845A may be positioned to partially overlap a bottom arc section of the cup holder 858. The compartment 856 that receives the movable wall 845A when stowed may include a cambered edge 857 that intersects with or is part of the lower arc section of the cup holder wall 858. The top edge 846 of the movable wall 845A may deploy and stow partially or completely from the cup holder 858. The top edge 846 of the movable wall 845A may be accessible from the bottom arc section of the cup holder 858 wall. This provides several new advantages for tray tables and the mono-slider embodiments. For example, overlapping the movable wall 845 A with the cup holder 858 saves sliding space, which permits for a shorter sliding length of the post 854 (between the torque tube 855 on one end and the lip 851 on the other end) while simultaneously still providing the movable wall 845A and cup holder 858 integrated into the post 854. The embodiment also helps save weight by reducing post 854 length and material. The overlap of elements also reduces loading moment on the post 854. In addition, overlapping a section of the movable wall 854A over an edge of the cup holder 858 provides easier access for the user to pull and deploy the movable wall 845A withDOCKET NO. NEX2-PAU01P-U finger access as there is now improved ergonomic clearance to allow fingers to comfortably grasp and pull open the movable wall 845A via an open space that already exists via the cup holder 858. FIG. 41 A shows the movable wall 845A in stowed position. FIG. 4 IB shows the movable wall 845 A partially opened as it is lifted from its overlap with the cup holder 858. FIG. 41C shows the movable wall 845A in a completely deployed position.

[0122] FIGs. 43A and 43B show a different embodiment of a tray table 930 assembly that modifies the mono-slider 950. The post 954 is shown in a partially retracted position within the shroud 932. The shroud 932 may include indents 936, similar to the indents 236 shown in FIGs. 11-13. The post 954 includes a compartment 956 similar to the compartment 156. In this embodiment, there is not necessarily a cup holder 158 positioned between the torque tube 955 and the shroud 932. The movable wall 945 may be modified to include multiple elements. For example, the movable wall 945 may include a U-shaped frame 944 that rotates from the compartment 956 via a hinge 941. The frame 944 may have a central opening that separates from pad 943. The pad 943 may serve as the outer shell of part 1065 (Fig 44B). Pad 943 houses the push-pull mechanism (when it is stowed) and protects it from external particles, dirt, and user interference that could damage the mechanism. The top edge of the frame 944 may include a cambered edge 946 which may be configured to provide a fingerhold to lift the frame 944 from its stowed position. As can also be seen, embodiments may include a shroud extender 832A similar to what is shown in FIG. 42 A.

[0123] FIGs. 44A and 44B, along with FIGs. 46A, 46B, and 46C show an embodiment of the tray table 1030 (which may be similar to the tray table 930) but is modified to include a holder system 1060 (for holding articles including PEDs) from a rear edge of the shroud 1032. The tray table 1030 is shown in a retracted and upright, stowed position. The holder system 1060 may be configured to deploy out of the rear of the slider post or pad 943A (shown in FIGs. 43 A, 43B) as one major advantage of U-shaped movable wall 945. For example, as shown in FIG. 44 A, the holder system 1060 may stow into the interior of the slider-post or pad 943A as the tray table 1030 is upright. Some embodiments include a recess or channel 1099 designed to secure the retaining wall 1075 in place through an interference fit. The support wall 1065 and ledge 1070 may be locked together by the user when the retaining wall 1075 is no longer needed. The ledge 1070 is to stow into the support wall 1065 by means of a retaining wall 1075, which is coupledDOCKET NO. NEX2-PAU01P-U to the ledge 1070. During the stowing operation, the retaining wall 1075 is inserted into a channel 1099 defined within the support wall 1065, thereby securing the ledge 1070 in place through an interference or guided fit. When operated, the holder system 1060 may be pulled down of the slider-post or pad 943 A. When deployed, it can be seen that the holder system 1060 includes a support wall 1065 and a ledge 1070 coupled to the support wall 1065. The ledge 1070 may include a retaining wall 1075 on the distal edge of the ledge 1070. In use, an article such as a PED may be placed within the ledge 1070 and held in place by the retaining wall 1075. As may be appreciated, the tray table 1030 provides the means to carry a PED device even when tray tables must be stowed. Additionally, the holder system 1060 can be used to watch an electronic device without the inconvenience of a tray table being in the way creating more space and comfort for the user. FIGs. 46A, 46B, and 46C show the internal mechanism 1080 for movement and connection of the support wall 1065 to slider post or pad 943 A. Springs 1082 may be coupled to a fixed part of the housing 1081. The housing 1081 may be part of the structure of support wall 1065. The housing 1081 includes an integrated carotid groove 1085 (heartshaped cam path) machined or molded into its structure. A fixed pin 1084 is affixed to the housing 1081. A pawl wire 1083 may be transversely mounted to the fixed pin 1084 and a pawl guide 1086 which is configured to operatively engage the groove 1085. This groove-pawl interface governs the position of the push-pull operation of the support wall 1065. The compression springs 1082 remain compressed when the support wall 1065 is in the fully inserted (stowed) position as represented in FIG. 46B. The pawl wire guide 1083 follows the linear segment of the carotid groove 1085 and locks into a terminal notch shown in FIG. 46B, where the support wall 1065 is held securely within the housing 1081 and the springs 1082 are not fully compressed but are under partial load as it is shown in FIG.46B.

[0124] During actuation (first push) the applied axial force causes the pawl guide 1086 to be displaced into the bottom of the curved segment of the heart-shaped path as shown in Figure 46A. This displacement releases the locking interface and permits the springs 1082 to expand, thereby directing the pawl guide 1086 into top of the groove 1085 ejecting the support wall 1065 outward into the extended position as shown in Figure 46C. A subsequent push causes the pawl wire 1083 to retrace the path, returning to the locking notch and re-stowing the support wall 1065, shown in Figure 46B.DOCKET NO. NEX2-PAU01P-U

[0125] FIGs. 45A and 45B show a tray table 1130 with a rotary holder 1160. The rotary holder 1160 may be positioned on a rear edge of the tray table 1130. In the tray able 1130 stowed upright position, the rotary holder 1160 may be on the bottom edge. The rotary holder 1160 may be configured to move from a closed position as shown in FIG. 45 A to an open position as shown in FIG. 45B. The rotary holder 1160 may include a round shell wall 1170 that is configured to rotate. When rotated into an open position, a ledge 1165 of the shell wall 1170 is exposed. The ledge 1165 is configured to hold objects such as PEDs.

[0126] Example Dimensions

[0127] In the description below, reference is made to elements of the first embodiments described above for sake of illustration. It will be understood that the dimensions and description of structure applies to the variants of each embodiment in addition to the embodiment referenced. The mono-slider 150 may have a sliding length that can vary, typically between 2 to 6 inches, depending on the sliding length requirements of the particular tray table 130, which are set by the airlines. A 3 -inch-long sliding length of arm 154 may include both the cup holder and the movable wall 145 that a 6 inch long sliding length contains. The mono-slider 150 width may vary between 2 to 7 inches depending on the shroud 132 width. The larger the shroud 132 width, the larger the mono-slider may be for improved sliding quality. The torque tube 155 and post 154 widths may vary depending on the sliding distance and it can also be set depending on the airline choice and can be made customizable to airline choosing. The thickness of the mono-slider 150 can range between 0. 01 to 0. 75 inches, and the thickness and design may vary depending on the length of the mono-slider 150. The thickness may vary with the sliding distance. Also, the thickness may vary according to the material and manufacturing process used to make the mono-slider 150. The size and design of the mono-slider 150 may be primarily driven by the design loads that are applied to shroud 132, in addition to design features of the movable wall 145 and cup holder 185.

[0128] Advantages of the Torque Tube Mono-slider

[0129] In many conventional uses, a conventional tray table may be mounted to the seat back of each passenger seat via a pair of retractable sliders that allow the tray table to be pulled toward the passenger when deployed. However, conventional tray tables typically have poor sliding quality due to problems related to binding of the components operableDOCKET NO. NEX2-PAU01P-U for the linear sliding of the tray table when deploying / retracting the tray table traditional shroud structure.

[0130] The binding phenomenon in aircraft tray tables typically occurs due to misalignments and inconsistencies in the sliding mechanisms, which can result in poor sliding quality and increased wear over time. This issue is prevalent for several reasons. One is when the contact surfaces for each slider are much smaller than the distance between the sliders, leading to an imbalance and binding during sliding operation and the second issue is related to many degrees of freedom and allowing the two sliders and torque tube to wobble and intend to move and rotate independently from each other, as there are several parts coupled together via joints but not fixed together. As a result, there is a need for new sliding mechanisms that eliminate some if not all root causes behind the binding associated with typical tray tables and create a more predictable and smooth sliding action. In addition to reducing binding and poor sliding quality seen in typical tray table, new sliding mechanisms may improve passenger experience due to improved ergonomics, reduce long term maintenance / repair costs, reduced weight, and simplified manufacturing and assembly.

[0131] As will be appreciated, the mono-slider 150 that comprises the integration of a mono-slider post 154 and torque tube 155 into a one-piece part addresses the aboveidentified deficiencies of conventional tray tables. The configuration balances load distribution, structural integrity (which supports weight saving), and sliding management, ensuring reliable and smooth sliding back and forth operation of tray table shroud 132 and / or compartment 131. This approach addresses common issues with poor sliding quality (which can be seen in the conventional dual tray table slider) by providing a more balanced and stable sliding mechanism, through reducing the number of joints and degrees of freedom the mono-slider 150 can rotate and move as one unit. By integrating the mono-slider post 154 and torque tube 155 into one integrated part, all the previous degrees of freedom to move and rotate found in conventional table slider that were one of the primary factors responsible for poor sliding quality have been eliminated.

[0132] The implementation of a single, centrally located mono-slider post 154 addresses several issues associated with poor sliding performance in tray table mechanisms. In this configuration, “centrally located” refers to the mono-slider post 154 being positioned along the longitudinal centerline of the tray table shroud 132. This central alignment allows forces applied to the tray such as by a passenger pressing on its front corner to beDOCKET NO. NEX2-PAU01P-U more evenly distributed across the sliding interface. As a result, the likelihood of binding due to uneven force distribution or localized pressure points is significantly reduced. A key benefit of the centralized slider configuration is its positive impact on what is referred to as the Binding Length Ratio, which quantifies the tendency of a sliding mechanism to bind under torque. The Binding Length Ratio is defined as the moment arm distance divided by the effective sliding surface. The moment arm refers to the distance from the point where force is applied such as a passenger pressing on the front comer of the tray to the center of resistance within the slider. The effective sliding surface is the contact area between the sliding components that supports the load and guides the tray’s motion. In dual-slider configurations, such as the conventional tray table shown in FIG. 1, the center of resistance is offset from the geometric center of the tray. This increases the moment arm, which in turn increases the binding ratio and the potential for torque- induced binding. In contrast, the centralized mono-slider design of tray table 130 minimizes the moment arm due to its symmetric placement and alignment with the tray’s centerline. This reduces torque and improves self-alignment under load, resulting in smoother operation. In essence, the centralized mono-slider post 154 enables more reliable and consistent performance compared to dual-slider systems. In order for a dualslider system to achieve similar binding resistance, both sliders would need to be placed directly at the center, effectively functioning as a mono-slider.

[0133] As may be appreciated, a one-piece mono-slider 150 with fewer moving parts means less complexity and elimination of all moving parts previously used together. A single post 154 mechanism fixed to the torque tube 155 has fewer points of potential failure or misalignment compared to a dual-slider setup. Given the constraint of maintaining structural integrity due to the limited thickness of the tray table shroud 132 and the housing the post 154 within the shroud 132, the width of post 154 may be balanced with the necessity to preserve the strength and durability of the tray 130. In some embodiments, the width of post 154 may be larger or up to 100% of the width of the shroud 132. However, extending the width of the post 154 may increase friction by enlarging the contact surface with the shroud 132.

[0134] The single, continuous body of mono-slider 150 leverages the principle of material continuity, eliminating mechanical joints and interruptions that typically introduce stress concentrations, misalignments, and added mass. This uninterrupted structure of the torque tube 155 integrated with the post 154 not only improves loadDOCKET NO. NEX2-PAU01P-U distribution and structural integrity but also enables weight optimization by allowing the use of high strength to weight ratio materials such aluminum and composites in place of steel sliders. With its superior strength to weight ratio, aluminum (or composites) paired with a continuous grain structure flow, the mono-slider 150 is structurally and mechanically superior to disrupted or randomly oriented grains of a material and reduced joint complexity further enhances the lightweight, high-performance characteristics (fracture toughness, corrosion resistance, creep resistance, mechanical strength) of the mono slider 150 assembly. Additionally, another key weight saving advantage of the mono-slider 150 is its tailored structure meets the demanding structural loading requirements specified by Aircraft Seat Design and Manufacturers. One of the most critical of these requirements involves a high load applied at the front corner of the tray table when it is fully deployed open.

[0135] In conventional dual-slider tray table system, this loading creates significant stress concentration on a single slider, as only one side bears the majority of the load due to its position relative to the applied force (front corner of table). The integrated mono slider 150 resolves this issue by combining three previously separate components; two sliders and the torque tube into a single, unified part. This consolidation allows for a structurally optimized design that distributes stress more efficiently under critical loading conditions. As a result, the one-piece mono-slider configuration not only enhances durability and reliability but also enables further weight savings by eliminating redundant material and optimizing geometry around the most demanding stress zones.
