As used herein, the word "exemplary" means "serving as an example, instance, or illustration." Any implementation described herein as exemplary should not necessarily be construed as preferred or advantageous over other implementations. Furthermore, it is not intended to be bound by any express or implied theory set forth in the foregoing technical fields, background art, summary of the invention, or the following detailed description.
[0036] The following description may refer to elements, nodes, or features being “coupled” together. As used herein, unless otherwise explicitly stated, “coupled” means that one element / node / feature is directly or indirectly connected to (or directly or indirectly communicated with) another element / node / feature, and not necessarily mechanically connected. Furthermore, certain terms may also be used in the following description for reference only and are not intended to be limiting. For example, terms such as “upper,” “lower,” “above,” “below,” refer to directions referenced in the accompanying drawings. Terms such as “front,” “rear,” “rear,” “side,” “outer,” and “inner” describe the orientation and / or position of multiple parts of a component within a consistent but arbitrary frame of reference, which is clearly defined by reference to the text describing the component under discussion and the associated drawings. Such terms may include the words specifically mentioned above, their derivatives, and words with similar meanings. Similarly, the terms “first,” “second,” and other such numerical terms referring to structures do not imply order or sequence unless explicitly indicated by the context.
[0037] This document discloses movable seats and related seating systems. According to certain non-limiting embodiments, the seating systems are deployed on vehicles such as airplanes, trains, buses, or ships. However, it should be understood that embodiments of the disclosed seating systems can be used for commercial, residential, or other applications. Exemplary implementations shown and described herein relate to movable seating systems on aircraft, wherein the seat position of the seating system is adjustable between an upright position and a flat position (including upright and flat positions). At least one passenger cushion (e.g., seat cushion, backrest cushion, headrest cushion, and / or leg cushion) is arranged and configured as a "shape-transforming" cushion with a variable surface profile that changes in response to adjustments in the seat position. For example, when the seating system is in a flat position (e.g., a configuration intended to accommodate a sleeping passenger), the cushion exhibits a relatively flat shape. Conversely, when the seating system is in an upright position or in a reclined or relaxed position, one or more passenger cushions are physically manipulated to provide a desired shape or profile intended to improve passenger comfort.
[0038] Refer to the attached diagram. Figures 1 to 5 This is a perspective view of the adjustable seating arrangement 100 in different positions. Figures 1 to 5The illustrated embodiment of the seating arrangement 100 includes two side-by-side seating systems 102, 104 and corresponding movable footstool components 106, 108 (footstool component 106 cooperates with seating system 102, and footstool component 108 cooperates with seating system 104). As described in more detail below, each footstool component 106, 108 is controlled to move automatically in coordination with the adjustments of its associated seating systems 102, 104. Although Figures 1 to 5 The arrangement depicted includes a pair of seat systems 102, 104, but the deployment may include only one seat system or two or more seat systems side by side.
[0039] The position of each seating system 102, 104 is adjustable (manually or electronically). In some embodiments, the seating arrangement 100 includes at least one electronically controlled actuation system that is activatable to adjust the seating systems 102, 104 between an upright position and a flat (sleeping) position (including upright and flat positions), having any number of intermediate positions between the upright and flat positions. In this respect, Figure 1 The two seating systems 102 and 104 are depicted in their upright positions; Figure 2 The seat system 102 is depicted in its upright position, and the seat system 104 is depicted in its reclined position; Figure 3 The two seating systems 102 and 104 are depicted in a reclining position; Figure 4 The seat system 102 is depicted in its upright position, and the seat system 104 is depicted in its flat position; and Figure 5 The two seating systems 102 and 104 are depicted in a flat position. Figure 6 It is a side perspective view depicting the seating system 102 itself in its upright position; Figure 7 It is a side perspective view depicting the seating system 102 itself in a reclining position; and Figure 8 This is a side perspective view depicting the seating system 102 itself in a flat position.
[0040] Figure 9 This is a simplified block diagram representation of a control system 200 applicable to adjustable seating systems of the type disclosed herein. For example, each seating system 102, 104 may include a corresponding instance of or cooperate with the control system 200. At the heart of the control system 200 is an electronically controlled actuation system 202, which is designed, programmed, and otherwise configured to control the adjustment of at least one movable component of the seating system. The illustrated embodiment is applicable to a seating system having an electric neck support component 204, an electric seat component 206, and an electric footrest component 208.
[0041] The neck support component 204 can be controlled to move automatically in coordination with the adjustment of the seat system to a reclined position. In this regard, the neck support component 204 can be controlled to move upward and forward only when the seat system is adjusted to a reclined position, and to automatically retract when the seat system is adjusted to an upright or flat position (in which neck support is not required). Alternatively or additionally, the neck support component 204 can be controlled by the occupant upon request. However, in certain environments, the activation of the neck support component 204 can be disabled or restricted to prevent interference with or contact with surrounding structures (e.g., paneling or trim around the seat system, interior walls of the aircraft cabin, cabinets or partitions, etc.).
[0042] Seat component 206 represents the main element of the seating system. As described in more detail below, seat component 206 includes three main sections that can move relative to each other when the seating system moves between an upright and a flat position. These main sections include a backrest section, a seat section, and a leg rest section. Figure 9 The backrest and seat sections are depicted as combined blocks with corresponding control signals or channels from the actuation system 202, and the leg rest section is depicted as a separate block with corresponding control signals or channels from the actuation system 202. In some embodiments, the leg rest section is controlled independently of the backrest and seat sections, but they can be controlled collaboratively. However, the leg rest section can automatically extend once the seat reaches a predetermined reclining angle. The seat component 206 can be controlled to adjust its reclining position. In some embodiments, the seat component 206 can also be controlled to move forward and backward. In some embodiments, the seat component 206 can also be controlled to adjust its height, or the height can be manually adjusted during installation (and does not need to be user-adjustable).
[0043] The footrest component 208 can be controlled to move automatically (forward and backward) in coordination with the adjustment of the seat system to a flat position. This allows the footrest component 208 to extend the effective length of the seat system to accommodate a sleeping or resting occupant. Alternatively or additionally, the footrest component 208 can be controlled by the occupant upon request. However, in certain environments, the activation of the footrest component 208 can be disabled or restricted to prevent interference with or contact with surrounding structures (e.g., paneling or trim around the seat system, interior walls of the aircraft cabin, cabinets or partitions, etc.).
[0044] Actuation system 202 can be activated (e.g., in response to user or occupant input) to generate appropriate commands, control signals, and / or outputs to adjust the movement, motion, or articulation of movable components of the seat system. Actuation system 202 can be activated to adjust the seat system to various seating positions, including but not limited to: an upright position; a flat position; and at least one reclining position between the upright and flat positions. For this purpose, actuation system 202 can generate and issue any of, but not limited to, the following commands and control signals: up and down commands for the neck support member 204; reclining position commands for the seat member 206; forward and backward commands for the seat member 206; height commands for the seat member 206; forward and backward commands for the footrest member 208; height commands for the footrest member 208; and tilt commands for the footrest member 208. In some embodiments, actuation system 202 can generate and issue independent commands or control signals associated with the adjustment of the leg rest section of the seat member 206. The actuation system 202 generates commands, control signals, and / or outputs that activate and regulate the operation of one or more electrical, mechanical, electromechanical, magnetic, pneumatic, and / or other components of the seating system, causing one or more movable parts to move to a desired position. In practice, the actuation system 202 can initiate or activate the movement of various internal structures, parts, and components of the seating system, which may include, but are not limited to: gears; mechanical linkages; push rods; hinges; bearings; joints; motors; support structures; frame elements; plates; wheels; pulleys; belts; or the like.
[0045] The actuation system 202 can respond to commands, settings, or instructions received from the user interface 210. In this regard, the user interface 210 can be an integrated element of the seating system, such as a control panel or touchscreen display with various buttons, switches, knobs, or other human-machine interface items. Alternatively or additionally, the actuation system 202 can respond to commands, settings, or instructions received from the remote control interface 212. In this regard, the remote control interface 212 can be implemented using a dedicated remote control device assigned to the seating system. In some implementations, the remote control interface 212 can be implemented as a suitably written application running on a mobile device owned or operated by the occupant, such as a mobile phone application or a smartwatch application. In other implementations, the remote control interface 212 can be implemented as a feature or application of a passenger entertainment system carried on an aircraft, train, or ferry.
[0046] Refer again Figures 1 to 8 Seat system 102 includes a backrest section 120, a seat section 122, a leg rest section 124, and an electric neck support component 126. Seat system 104 also includes a backrest section 130, a seat section 132, a leg rest section 134, and an electric neck support component 136. Figure 1The diagram shows both seating systems 102 and 104 in their upright positions, while... Figure 6 Only one seating system (e.g., seat system 102) is shown in its upright position. In aircraft applications, the upright position corresponds to the seating position during taxiing, takeoff, and landing (TTL). Figure 1 As shown, when the seat systems 102 and 104 are in their upright position, the leg rest sections 124 and 134 are retracted (i.e., pulled inward toward the backrest sections 120 and 130), and the corresponding footrest components 106 and 108 are positioned to provide ample legroom for the occupant. Furthermore, when the seat systems 102 and 104 are in their upright position, the neck support components 126 and 136 are fully retracted (i.e., moved toward the top of the backrest sections 120 and 130).
[0047] Figure 5 The two seating systems 102 and 104 are shown in a flat position (suitable for sleeping), while Figure 8 Only one seating system (e.g., seating system 102) is shown in a flat position. Figure 5 As shown, when the seat systems 102 and 104 are in the flat position, the backrest sections 120 and 130, seat sections 122 and 132, and leg rest sections 124 and 134 are positioned to create a nominally flat surface for the occupant. Furthermore, footrest components 106 and 108 are positioned adjacent to and abutting (or nearly abutting) the terminal edges of the leg rest sections 124 and 134 (see...). Figure 5 It is desirable to adjust and position the footstool components 106 and 108 in this way to create a longer sleeping surface for the occupant, which provides additional legroom.
[0048] Seating systems 102 and 104 can be adjusted to at least one intermediate seating position between an upright and a flat position. In some embodiments, for example, seating systems 102 and 104 can be continuously adjusted to any intermediate position between an upright and a flat position. In some embodiments, seating systems 102 and 104 can be adjusted to one or more predefined or specified intermediate positions between an upright and a flat position. The exemplary embodiments described herein assume that seating systems 102 and 104 can be adjusted to at least one reclining position between an upright and a flat position.
[0049] Figure 3 The diagram shows both seating systems 102 and 104 in a reclining position, while... Figure 7 Only one seating system (e.g., seating system 102) is shown in a reclined position. Figure 3As shown, when the seat systems 102 and 104 are in the reclined position, the backrest sections 120 and 130 are reclined, the seat sections 122 and 132 are tilted at a slightly upward angle (where the front of the seat sections 122 and 132 is higher than the rear of the seat sections 122 and 132), and the leg rest sections 124 and 134 are angled downward (where the front of the leg rest sections 124 and 134 is lower than the rear of the leg rest sections 124 and 134). Furthermore, when the seat systems 102 and 104 are in the reclined position, the neck support members 126 and 136 can be fully extended (i.e., moved away from the top of the backrest sections 120 and 130). Figure 3 In the depicted embodiment, footstool components 106, 108 are positioned adjacent to and abutting (or nearly abutting) the terminal edges of leg rest sections 124, 134 (see... Figure 3 ).
[0050] In some embodiments, each seat system 102, 104 is independently controllable and independently adjustable. In this respect, Figure 2 A seat system 102 in an upright position and a seat system 104 in a reclining position are depicted. As another example, Figure 4 Seating system 102 in an upright position and seating system 104 in a flat position are depicted. Although this description emphasizes three common preset seating positions (e.g., upright, reclined, and flat), it is possible to adjust each seating system 102, 104 to additional and / or alternative positions depending on the specific embodiment of the seating arrangement.
[0051] Seat systems 102 and 104 include various support structures (e.g., support hardware, frame components, structural members, and other elements) that carry and support the occupant cushion. For simplicity and clarity, the following description refers to seat system 102 and its corresponding components; the description of seat system 102 also applies to seat system 104. The embodiments disclosed herein include a seat cushion 150 (which can be considered part of a seat section), a backrest cushion 152 (which can be considered part of a backrest section), and a leg rest 154 (which can be considered part of a leg support section). The seat cushion 150... Figure 3 and Figures 5 to 8 The label indicates that the backrest cushion is 152. Figure 1 , Figure 3 and Figures 6 to 8 The label indicates that the leg pads are 154mm in size. Figure 1 , Figure 3 and Figures 5 to 8 As indicated in the text. The neck support component 126 and the footrest component 106 may also include corresponding pads (not separately indicated).
[0052] At least a portion of the neck support member 126, at least a portion of the backrest cushion 152, at least a portion of the seat cushion 150, and at least a portion of the leg rest 154 may be covered and protected by the blanket assembly 160. For the illustrated embodiment, the blanket assembly 160 covers the occupant-facing surface of the cushions. The blanket assembly 160 may be attached to appropriate portions of the underlying support structure or frame of the seat system 102. Alternatively or additionally, selective areas or sections of the blanket assembly 160 may be attached to one or more cushions, for example, using clips, hook-and-loop fasteners, zippers, or buckles. The blanket assembly 160 may also be used to retain one or more cushions in place in positions covering the corresponding support structure or frame of the seat system 102.
[0053] At least one cushion is designed and configured to change shape and / or profile in response to changes in seat position. More specifically, adjustments of the seat system 102 to different positions are associated with changes in the configuration, arrangement, orientation, and / or layout of the underlying support structure, which alters the shape and / or profile of the cushion. According to the embodiments described herein, the backrest cushion 152 and seat cushion 150 change shape in response to adjustments of the seat system 102 to different positions. It should be understood that the shape-changing characteristic may also be applied to the leg cushion 154, neck support member 126, and / or footrest member 106 if desired.
[0054] refer to Figure 5 and Figure 8 When the seat system 102 is in the flat position, the support structure of the seat cushion 150 is held in a flat state or configuration, giving the seat cushion 150 a nominally flat shape that provides a relatively flat occupant-facing surface. Similarly, the support structure of the backrest cushion 152 is held in a flat state or configuration, giving the backrest cushion 152 a nominally flat shape that provides a relatively flat occupant-facing surface. In the flat position, the blanket assembly 160 can be stretched and held under tension to help maintain the flat shape of the cushion.
[0055] refer to Figure 1 and Figure 6 When the seat system 102 is in the upright position, the support structure of the seat cushion 150 is held in its upright state or configuration, such that at least a portion of the seat cushion 150 has a convex shape that provides a contoured and slightly raised surface facing the occupant. Similarly, the support structure of the backrest cushion 152 is held in its upright state or configuration, such that at least a portion of the backrest cushion 152 has a convex shape that provides a contoured and slightly raised surface facing the occupant (for lower back support and / or lumbar support). Figure 6 The convex shape of the seat cushion 150 and the backrest cushion 152 can be seen more clearly in the image.
[0056] refer to Figure 3 and Figure 7 When the seat system 102 is in a reclined position, the support structure of the seat cushion 150 is held in the reclined state or configuration, such that at least a portion of the seat cushion 150 has a convex shape, providing a contoured and slightly raised surface facing the occupant. Similarly, the support structure of the backrest cushion 152 is held in the reclined state or configuration, such that at least a portion of the backrest cushion 152 has a convex shape, providing a contoured and slightly raised surface facing the occupant (for lower back support and / or lumbar support). Figure 7 The convex shapes of the seat cushion 150 and backrest cushion 152 can be seen more clearly in the image. Although not always necessary, the shape and profile of the backrest cushion 152 may change when transitioning between upright and reclined positions, and the shape and profile of the backrest cushion 152 in the upright position may differ from that in the reclined position. Similarly, the shape and profile of the seat cushion 150 may change when transitioning between upright and reclined positions, and the shape and profile of the seat cushion 150 in the upright position may differ from that in the reclined position.
[0057] According to some embodiments, the support structure for the shape-changing pad has a variable physical configuration that changes in response to adjustments in the seat position of the seating system. The support structure directly or indirectly supports the shape-changing pad in different patterns corresponding to different seat positions. The shape-changing pad responds to changes in the physical configuration of the underlying support structure, causing the shape and / or contour of the seat surface to adapt in the desired manner.
[0058] Figure 10 and Figure 11 This is a bottom perspective view of an adaptive contour conversion cushion 250 suitable for an adjustable seating system of the type disclosed herein. As described above, at least the seat cushion 150 and the backrest cushion 152 can be implemented in a manner consistent with that described herein with respect to the cushion 250. Figure 10 The pad 250 is depicted in its nominally flat state, while Figure 11 The pad 250 is depicted in a curved or contoured state. For clarity and ease of description, Figure 11 The curvature of the pad is exaggerated by 250.
[0059] Pad 250 typically includes, but is not limited to: an occupant-facing surface 252; a bottom surface 254 opposite to the occupant-facing surface 252; and cushioning material (in... Figure 10 and Figure 11 (Hidden and not visible); hinged arrangement of pad support members 256; and a covering 258 that covers and surrounds the cushioning material. Figure 10 and Figure 11 In the middle, most of surface 252 is hidden and not visible because surface 252 defines the top surface of pad 250, while Figure 10 and Figure 11The bottom of the pad 250 is shown. For this particular embodiment, the arrangement 256 of the pad support members is combined to define a bottom surface 254. In this respect, the pad support members 256 are movably coupled together to create a dynamically adjustable and movable bottom surface 254 of the pad 250.
[0060] The cushioning material may be applied to, molded around, adhered to, or otherwise carried by the arrangement 256 of the pad support members. The cover 258 may be made of any suitable material and may be implemented as a one-piece component or may consist of multiple segments, panels, or sheets. The cover 258 is installed to cover the cushioning material. At least a portion of the cover 258 may be adhered to the arrangement 256 of the pad support members and / or to the cushioning material. According to the illustrated embodiment, the cover 258 overlaps with the sidewalls of the cushioning material and with at least a portion of the arrangement 256 of the pad support members. The edge portions of the cover 258 may be adhered to or attached to the arrangement 256 of the pad support members in any suitable manner. For example, the cover 258 may be glued or bonded to the arrangement 256 of the pad support members. Alternatively or additionally, the cover 258 may be attached to the arrangement 256 of the pad support member using fasteners such as snaps, hooks and loops, clips, screws or bolts, buttons or any type of fastening system.
[0061] In some embodiments, the arrangement 256 of the pad support members includes a plurality of rigid plates 264 (which may be flat or profiled) coupled together via hinged joints 266. The plates 264 are preferably made of strong, lightweight, and rigid materials (or combinations thereof), including but not limited to: aluminum, steel, plastics, and composite materials. The illustrated embodiment includes eight rectangular plates 264, which are horizontally oriented and movably coupled together via horizontally oriented hinged joints 266. Figure 10 As shown, the hinged joints 266 are arranged parallel to each other. In an alternative embodiment, the arrangement 256 of the pad support members may include more or fewer than eight plates 264, which need not be rectangular or regular in shape, need not be of the same shape or size, and need not be restricted to any particular direction or dimension (e.g., see...). Figure 15 , Figure 20 and Figure 25 (These depict exemplary arrangements of such rigid plates). In alternative embodiments, plates 264 may be movably coupled together using components or features other than hinges.
[0062] The overall shape and profile of the pad 250 change in response to the movement of the arrangement 256 of the pad support members. In this respect, Figure 11The curvature of pad 250 is depicted, where plates 264 are no longer arranged in a flat and coplanar orientation. Instead, adjacent plates 264 are angled relative to each other due to pivoting about corresponding hinged joints 266. The curvature of the arrangement 256 of the pad support members results in corresponding curvatures of the cushioning material, covering 258, and occupant-facing surface 252. When the arrangement 256 of the pad support members is as described... Figure 11 When positioned as shown (resulting in a recessed bottom surface 254), at least a portion of the pad 250 bulges, causing the occupant-facing surface 252 to exhibit a raised side profile shape. Conversely, when the pad support members are arranged 256 as... Figure 10 When positioned as shown (resulting in a relatively flat and planar bottom surface 254), the occupant-facing surface 252 exhibits a nominally flat side profile shape. In other words, the pad 250 no longer has any significant or noticeable bulges or protrusions on the occupant-facing surface 252.
[0063] The arrangement 256 of the cushion support member moves cooperatively with the underlying support structure of the seat systems 102, 104. In some embodiments, the arrangement 256 of the cushion support member is coupled to at least one movable support structure of the seat systems 102, 104 using fasteners, adhesives, or other attachment means. In other embodiments, the arrangement 256 of the cushion support member is securely held against at least one movable support structure of the seat systems 102, 104 (without using fasteners, adhesives, or other attachment means). In other embodiments, the arrangement 256 of the cushion support member is coupled to or integrated with the support structure of the seat systems 102, 104 (rather than with the cushion 250), and the cushion 250 rests against or is coupled to the arrangement 256 of the cushion support member.
[0064] Now refer to Figures 12 to 31 The figures depict the internal components and support structures of the seat systems 102 and 104, illustrating the support structures, frame elements, and connecting parts of the adjustable seat systems 102 and 104 of the type disclosed herein. Figures 12 to 16 and Figures 27 to 31 Corresponding to the upright positions of adjustable seat systems 102 and 104; Figures 17 to 21 Corresponding to the reclining positions of adjustable seat systems 102 and 104; and Figures 22 to 26 This corresponds to the flat position of the adjustable seat systems 102 and 104. Figures 12 to 31 The internal mechanisms, hardware, and support structures of the seating systems 102 and 104 are shown, without any padding, decoration, covering materials, blankets, etc. Figure 12 , Figure 17 , Figure 22 and Figures 27 to 31 It is an outside view. Figure 13 , Figure 18 , Figure 23 Is with Figure 12 , Figure 17 and Figure 22 The inner view corresponding to the outer view (showing some components viewed from inside the adjustable seat system 102, 104). Figures 14 to 16 , Figures 19 to 21 and Figures 24 to 26 This is a perspective side view showing a portion of the seating system 102. For simplicity, clarity, and ease of explanation, some structural components are shown... Figures 12 to 31 It is not depicted or is not fully depicted.
[0065] like Figures 12 to 31 Some embodiments of the depicted seating systems 102, 104 include, but are not limited to, the following components: a base support structure 302; a seat support structure 304 movably coupled to the base support structure 302; a backrest support structure 306 movably coupled to the base support structure 302; a leg rest support structure 308 movably coupled to the base support structure 302; and a neck support support structure 310 movably coupled to the base support structure 302. The seat support structure 304 and / or the base support structure 302 support the seat cushion, the backrest support structure 306 supports the backrest cushion, the leg rest support structure 308 supports the leg rest, and the neck support support structure 310 supports or integrates with an electric neck support component.
[0066] According to the illustrated embodiment, the seat support structure 304 is movably coupled to or near the final section of the base support structure 302, allowing the seat support structure 304 to tilt upward relative to the base support structure 302. According to the illustrated embodiment, the backrest support structure 306 is also movably coupled to or near the final section of the base support structure 302, allowing the backrest support structure 306 to recline backward relative to the base support structure 302. Although not always necessary, the seat support structure 304 and the backrest support structure 306 can be pivotally coupled to the base support structure 302 at a common hinge point. According to the illustrated embodiment, the leg rest support structure 308 is indirectly coupled to the base support structure 302 via the seat support structure 304. For example, the leg support structure 308 may be pivotally coupled to or near the front section of the seat support structure 304, allowing the leg support structure 308 to extend and retract relative to the front of the seat support structure 304 and relative to the front section of the base support structure 302. According to the illustrated embodiment, the neck support structure 310 is indirectly coupled to the base support structure 302 via the backrest support structure 306. For example, the neck support structure 310 may be integrated with or coupled to the top section of the backrest support structure 306 in a manner that allows the neck support structure 310 to extend as needed (see...). Figure 2 and Figure 7) and retraction (see Figure 1 and Figure 6 In this regard, the seat systems 102, 104 may include a suitably configured drive mechanism 316, which may be electronically controlled to actuate the neck support structure 310 on demand (e.g., deploy and store) or automatically as needed.
[0067] Figure 12 , Figure 13 , Figure 15 , Figure 17 , Figure 18 , Figure 20 , Figure 22 , Figure 23 , Figure 25 and Figures 27 to 31 The hinged arrangement 324 of the seat cushion support member (without its associated seat cushion component) and the hinged arrangement 326 of the backrest cushion support member (without its associated backrest cushion component) are depicted. The arrangements 324 and 326 of the cushion support members are shown to demonstrate how they change shape and profile in response to adjustments in seat position. More specifically, the arrangements 324 and 326 of the cushion support members follow the shape and profile of their underlying support structure, the shape and profile of which change cooperatively with adjustments in seat position (as referenced above). Figure 10 and Figure 11 The arrangement of the pad support members shown in Figure 256 is explained. (See reference...) Figure 22 , Figure 23 and Figure 25 When the seat systems 102 and 104 are in a flat position, the arrangements 324 and 326 of the two pad support members are relatively flat and define a surface that is essentially planar. This is due to the relatively flat and / or relatively planar underlying support surface. Conversely, Figure 12 , Figure 13 , Figure 15 , Figure 17 , Figure 18 , Figure 20 and Figures 27 to 31 Corresponding to various non-flat seat positions, the arrangement of cushion support members 324, 326 is no longer flat or planar because their underlying support surface has been changed.
[0068] In some embodiments, the base support structure 302 includes or defines at least one flat seat support surface 330, 332 that supports the seat cushion when the seat systems 102, 104 are in a flat position. In the flat position, the hinged arrangement 324 of the seat cushion support members is physically adapted to conform to at least one flat seat support surface 330, 332. The flat seat support surface 330 corresponds to the top surface of the left / right sidewall, left / right frame, or left / right track of the base support structure 302. According to the depicted embodiment, at least one flat seat support surface 330 is located on the left side of the seat systems 102, 104, and at least one flat seat support surface 330 is located on the right side of the seat systems 102, 104.
[0069] exist Figure 22 , Figure 23 and Figure 25 In this configuration, the flat seat support surface 330 is continuous with the bottom surface of the arrangement 324 of the seat cushion support members. The flat seat support surface 332 corresponds to the top surface of the movable left / right frame members 334. According to the depicted embodiment, one movable frame member 334 is located on the left side of the seat systems 102, 104, and the other movable frame member 334 is located on the right side of the seat systems 102, 104. Figures 22 to 24 As shown, the flat seat support surface 332 may be continuous with the flat seat support surface 330. According to the illustrated embodiment, each frame member 334 rotates about a horizontal axis located at or near its front end. Therefore, when the seat systems 102, 104 transition to the flat position, the frame member 334 tilts upward to ultimately provide a flat seat support surface 332 for the arrangement 324 of the seat cushion support members. When the seat systems 102, 104 transition from the flat position, the frame member 334 tilts downward, causing the top surface of the frame member 334 to move away from and disengage from the arrangement 324 of the seat cushion support members.
[0070] The backrest support structure 306 is configured and controlled to support the backrest cushion. In some embodiments, the backrest support structure 306 includes a main frame 338, a hinged frame 340 movably coupled to the main frame 338, and a lumbar frame 341 movably coupled to the hinged frame 340. The main frame 338 includes or defines at least one flat back support surface 342 that supports the backrest cushion when the seat systems 102, 104 are in a flat position (see...). Figure 16 , Figures 21 to 24 and Figure 26In the flat position, the hinged arrangement 326 of the backrest support member is physically adapted to conform to at least one flat backrest support surface 342. The flat backrest support surface 342 corresponds to the top surface of the left / right side wall, left / right section, or left / right track of the main frame 338. According to the depicted embodiment, at least one flat backrest support surface 342 is located on the left side of the seat system 102, 104, and at least one flat backrest support surface 342 is located on the right side of the seat system 102, 104. As explained in more detail below, the hinged frame 340 is positioned such that it does not contact the arrangement 326 of the backrest support member when the seat system 102, 104 is in the flat position. In this respect, when the seat system 102, 104 transitions to the flat position, the hinged frame 340 moves downward relative to the top surface of the main frame 338, eventually descending below the main frame 338 and disengaging from the arrangement 326 of the backrest support member.
[0071] When the seat systems 102 and 104 are adjusted to a flat position (e.g.) Figures 22 to 26 As shown, at least a portion of the seat cushion 150 flattens on at least one flat seat support surface 330, 332, such that the occupant-facing seat surface exhibits a nominally flat side profile shape. Similarly, when the seat systems 102, 104 are adjusted to a flat position, at least a portion of the backrest cushion 152 flattens on at least one flat back support surface 342, such that the occupant-facing backrest surface of the backrest cushion 152 exhibits a nominally flat side profile shape.
[0072] Figures 12 to 16 The support structure of the seating systems 102 and 104 in the upright position is shown. In the upright position, the arrangements 324 and 326 of the cushion support members are profiled due to the corresponding curvature characteristics of their underlying support surfaces. More specifically, the arrangement 324 of the cushion support members is no longer fully supported by the flat seat support surfaces 330 and 332, and the arrangement 326 of the backrest cushion support members is no longer fully supported by the flat back support surface 342.
[0073] In some embodiments, the seat support structure 304 includes or defines at least one contoured seat support surface 350 that supports the seat cushion when the seat systems 102, 104 are in an upright position. In the upright position, the hinged arrangement 324 of the seat cushion support members is physically adapted to conform to at least one contoured seat support surface 350. According to the depicted embodiment, one contoured seat support surface 350 corresponds to the top surface of the left arm, left frame, or left rail of the seat support structure 304, and another contoured seat support surface 350 corresponds to the top surface of the right arm, right frame, or right rail of the seat support structure 304. According to the depicted embodiment, at least one contoured seat support surface 350 is located on the left side of the seat systems 102, 104, and at least one contoured seat support surface 350 is located on the right side of the seat systems 102, 104. In some embodiments, the contoured seat support surface 350 may be implemented as a continuous upper edge surface that spans between the two ends of the seat support structure 304.
[0074] Figure 14 , Figure 16 , Figure 19 and Figure 21 The curved side profile of the contoured seat support surface 350 is best shown. Figure 13 From left to right, the side profile exhibits a raised section on or near the left side, an inflection point in or near the middle, and a recessed section on or near the right side. When the seat systems 102 and 104 are in the upright position, the curvature of the contoured seat support surface 350 affects the curvature, profile, and shape of the hinge arrangement 324 of the seat cushion support member. When the seat systems 102 and 104 are in the reclined position, the arrangement 324 of the seat cushion support member also rests against the contoured seat support surface 350. However, when the seat systems 102 and 104 are in the... Figures 17 to 21 In the reclining position shown, the rear section of the seat cushion support member arrangement 324 is no longer supported by the contoured seat support surface 350. Instead, the rear section of the seat cushion support member arrangement 324 is supported by the flat seat support surface 332 of the movable left side frame member 334.
[0075] In some embodiments, the backrest support structure 306 includes an adjustable lumbar frame 341, which can be configured to accommodate an occupant as desired. The lumbar frame 341... Figure 12 , Figure 14 , Figure 17 , Figure 19 , Figure 22 and Figures 27 to 31The lumbar frame 341 is optimally depicted. It is adjustablely coupled to the hinge frame 340 at an upper hinge or pivot point, allowing the lumbar frame 341 to rotate (within certain limits) relative to the hinge frame 340. When adjusting the position of the seat systems 102, 104, the hinge frame 340 and / or the lumbar frame 341 can (but need not) be configured and controlled to move relative to each other. According to some embodiments, the position of the lumbar frame 341 relative to the hinge frame 340 can be adjusted (e.g., customized for passengers according to aircraft specifications to increase or decrease lower back or lumbar support) and set during the manufacture of the seat systems 102, 104. In such embodiments, subsequent adjustments to the lumbar frame 341 relative to the hinge frame 340 may be inhibited due to a lack of accessibility. Reference will be made below. Figures 27 to 31 The adjustment of the waist frame 341 is described in more detail.
[0076] According to the illustrated embodiment, the hinged frame 340 (and lumbar frame 341) includes or defines at least one contoured back support surface 354 that supports the backrest cushion when the seating system 102, 104 is in an upright position (e.g., see...). Figure 12 , Figure 14 and Figure 16 In the upright position, the hinged arrangement 326 of the backrest cushion support members is physically adapted to conform to at least one contoured back support surface 354. According to the illustrated embodiment, one contoured back support surface 354 corresponds to the top surface of the left hinge frame 340 of the backrest support structure 306, and another contoured back support surface 354 corresponds to the top surface of the left lumbar frame 341 of the backrest support structure 306. As shown, the contoured back support surface 354 can be implemented as a continuous upper edge surface spanning between the two ends of the hinge frame 340. Other similarly configured contoured back support surfaces 354 correspond to the top surfaces of the opposing right hinge frame 340 and the opposing left lumbar frame 341 of the backrest support structure 306.
[0077] exist Figure 12 , Figure 13 , Figure 17 , Figure 18 , Figure 22 and Figures 27 to 31 The side view better illustrates the curved side profile of the contoured back support surface 354. The side profile resembles a wing, exhibiting a more prominent raised section in or near the lower section of the articulated frame 340. This prominent raised section is designed and positioned to provide lower back support for the occupant. As described above, the lumbar frame 341 can be independently adjusted to change the shape of the side profile of the contoured back support surface 354 (see...). Figures 27 to 31When the seat systems 102 and 104 are in an upright position, the curvature of the contoured back support surface 354 affects the curvature, contour, and shape of the hinge arrangement 326 of the backrest cushion support member. When the seat systems 102 and 104 are in certain reclining positions, such as... Figures 17 to 21 In the reclining position shown, the arrangement 326 of the backrest cushion support members also rests against the contoured backrest support surface 354. However, as the seat systems 102, 104 recline further (to a flat position), the hinge frame 340 begins to retract below the main frame 338. As a result, in some reclining positions, the arrangement 326 of the backrest cushion support members is no longer fully supported by the contoured backrest support surface 354.
[0078] When the seat systems 102 and 104 are adjusted to the upright position, at least one contoured seat support surface 350 causes a portion of the seat cushion 150 to bulge, resulting in a raised side profile shape on the occupant-facing seat surface. Similarly, when the seat systems 102 and 104 are adjusted to the upright position, at least one contoured back support surface 354 causes at least a portion of the backrest cushion 152 to bulge, resulting in a raised side profile shape on the occupant-facing backrest surface of the backrest cushion 152.
[0079] Figures 17 to 21 Seating systems 102 and 104 are shown in a reclined position, which lies between an upright position and a flat position. When seat systems 102 and 104 are in this reclined position, at least one contoured seat support surface 350 supports the seat cushion, such that the hinged arrangement 324 of the seat cushion support member is physically adapted to conform to at least one contoured seat support surface 350. In this respect, the seat cushion exhibits a non-flat and non-planar upper surface that follows the contour of the underlying support structure. Furthermore, when seat systems 102 and 104 are in this reclined position, at least one contoured back support surface 354 supports the backrest cushion, such that the hinged arrangement 326 of the backrest cushion support member is physically adapted to conform to at least one contoured back support surface 354. Therefore, the backrest cushion exhibits a non-flat and non-planar upper surface that follows the contour of the underlying support structure.
[0080] Figure 27 and Figure 28 The adjustable nature of the seat support structure 304 is shown; it can be adjusted and positioned in multiple different locations to accommodate different occupants. More specifically, Figure 27 The image shows the seat support structure 304 in a raised or lifted state, while Figure 28 The seat support structure 304 is shown in a lowered state. In some embodiments, the seat support structure 304 accommodates more than two height settings. For example... Figure 14 , Figure 19As shown, the seat support structure 304 may include two adjacent rails on the right and two adjacent rails on the left (not fully shown). One or both of the adjacent rails may be raised or lowered as needed to adjust the height of the contoured seat support surface 350 of the hinged arrangement 324 supporting the seat cushion support member. In the illustrated embodiment, the outer rail is stationary, and its upper surface supports the seat cushion support member 324 in the lowered state of the seat support structure 304. Conversely, the inner rail is movable, and its upper surface supports the seat cushion support member 324 in the raised or lowered state of the seat support structure 304. For this purpose, the inner rail may pivot about an axis located near the rear end of the inner rail. According to some embodiments, the position of the movable rail may be adjusted (e.g., customized for passengers to increase or decrease thigh support according to aircraft specifications) and set during the manufacture or installation of the seat systems 102, 104. In such embodiments, subsequent height adjustment of the seat support structure 304 may be inhibited due to a lack of accessibility.
[0081] Figure 27 , Figure 29 and Figure 30 The adjustable nature of the hinged frame 340 of the backrest support structure 306 is shown; it can be adjusted and set in multiple different positions to change the lumbar support depth. More specifically, Figure 27 The hinged frame 340 is shown in the middle position. Figure 29 A hinged frame 340 is shown positioned in the forward position, while Figure 30 The hinged frame 340 is shown in the rearward position. Different positions can be selected by moving the bottom end of the hinged frame 340 forward / backward; the selected position can be secured using screws, bolts, or any suitable fasteners.
[0082] Figure 29 and Figure 31 The adjustable nature of the lumbar frame 341 of the backrest support structure 306 is shown; it can be adjusted and positioned in multiple different locations to change the shape of the lumbar support. More specifically, Figure 29 The waist frame 341 is shown in the forward position, while Figure 31 A waist frame 341 is shown in a rearward position. One or more intermediate positions of the waist frame 341 can also be supported. Different positions can be selected by pivoting the waist frame 341 relative to the hinged frame 340; the selected positions can be secured using screws, bolts, or any suitable fasteners.
[0083] As described above, the positions of the hinge frame 340 and the lumbar frame 341 can be selected and fixed during the manufacture or installation of the seat systems 102, 104. In such embodiments, subsequent adjustments to the hinge frame 340 and the lumbar frame 341 may be inhibited due to a lack of accessibility.
[0084] As described above, the actuation system 202 can be activated to adjust the seat position of the seat systems 102, 104. In this regard, the actuation system 202 can be controlled to adjust the position and orientation of various support structures relative to each other. For example, the actuation system 202 can be activated to adjust the tilt angle of the seat cushion by pivoting the seat support structure 304 relative to the base support structure 302. As another example, the actuation system 202 can be activated to adjust the tilt angle of the backrest cushion by pivoting the backrest support structure 306 relative to the base support structure 302. Furthermore, the actuation system 202 can be activated to adjust the tilt angle of the leg rest by pivoting the leg support structure 308 relative to the seat support structure 304. The accompanying drawings illustrate the manner in which the support structures move in coordination with each other. For this purpose, the seat systems 102, 104 may include an arrangement of movable, pivotable and / or translatable links, rods, plates or other elements coupled together in a suitable manner. This arrangement of the components is actuated to cause the backrest support structure 306, seat support structure 304, and leg support structure 308 to move in a coordinated manner. The arrangement of the components can also be suitably configured to move the neck support structure 310 in a cooperating manner. Alternatively or additionally, the seat systems 102, 104 may include a separate, controllable drive mechanism 316 dedicated to the neck support structure 310.
