Accordingly, elements with like element numbering may be shown in the figures, but may not necessarily be repeated herein for the sake of clarity.

[0033] Disclosed herein is a cabin attendant seat (CAS) that may be installed on a monument or bulkhead as a two-part assembly with a gap between an upper unit and a lower unit. The lower unit may carry the majority of flight load and crash loads, for instance, and the upper unit may include a headrest and mounting frame. The gap between the units allows room for a door split-line line, a hinge-line, and/or a slide-out table to extend between the two units at work-deck height. Due to the separated configuration of the two units, the upper unit can be mounted and movable on a separate surface from the lower unit, and vice versa. For instance, one surface may be fixed while the other is articulating, or both surfaces may be articulating.

[0034] With reference to FIG. 1, there is illustrated an example aircraft 100 that may incorporate one or more split cabin attendant seats (CAS) in accordance with this disclosure. The aircraft 100 includes a fuselage 102 having plurality of exit doors, including an exit door 104. Aircraft 100 includes one or more CAS (e.g., seat 200 described herein) positioned near a corresponding exit door 104. For example, aircraft 100 includes seat 200 positioned near exit door 104. While seat 200 is disclosed as positioned near exit door 104, it is further contemplated and understood that one or more CAS may be located at other locations. Although shown in FIG. 1 generally as a turbofan aircraft in which the engines are gas turbine engines, it should be noted that the aircraft 100 can be any suitable type of aircraft having any suitable number of engines of any suitable type.

[0035] Referring now to FIGS. 2A-2C, a cabin attendant seat (CAS) 200 (referred to herein as seat 200) is illustrated, in accordance with various embodiments. Seat 200 includes a housing 202. Housing 202 may provide structural support for seat 200. In this regard, housing 202 may be secured to an aircraft structure, such as a floor or a wall (e.g., of a galley) of an aircraft. In various embodiments, housing 202 may be a 2.0 ft-4.0 ft (e.g., 0.61 m-1.22 m) monument. Housing 202 includes opposing first and second walls 204a, 204b. First and second walls 204a, 204b each extend from a head end 206 of housing 202 to a foot end 208 of housing 202. Seat 200 includes an upper portion 210 and a lower portion 212. The upper portion 210 and the lower portion 212 are discrete portions of the seat 200 such that the upper portion 210 is configured to function (e.g., move, rotate relative to the housing 202, etc.) independently from the lower portion 212.

[0036] Seat 200 includes a headrest 218. Particularly, the upper portion 210 comprises the headrest 218. Headrest 218 may be located proximate head end 206 of housing 202. Headrest 218 may be pivotably (e.g., rotatably) coupled to housing 202. For instance, the headrest 218 may be coupled to the upper portion 210 via a hinge 219 such that headrest 218 may be configured to rotate along an axis perpendicular to the first and second walls 204a, 204b such that a user (e.g., a flight attendant) can use the headrest 218 as a platform when extended at least substantially perpendicularly from the housing 202 (e.g., see FIG. 2C). For instance, the headrest 218 as the platform may be used as a workstation, a bar, table, a serving table, tray, etc., as described further herein. As used herein, a platform may refer to any surface suitable for supporting the relevant work equipment, beverage, etc. For instance, the platform may be substantially parallel to the aircraft floor (e.g., perpendicular to the respective housing/monument). In various embodiments, the platform may be angled up to a 45 degree angle (e.g., to be compatible with various tablet and heights of users).

[0037] Further, seat 200 includes a seat pan 220 and a backrest 222. Particularly, the lower portion 212 may comprise the seat pan 220 and the backrest 222. Backrest 222 may be located generally between seat pan 220 and headrest 218. For instance, the headrest 218 and the backrest 222 may be separated by a gap having a distance of approximately 1.0 in-4.0 in (e.g., 2.54 cm-10.16 cm). Seat pan 220 may be configured to rotate relative to housing 202. In various embodiments, seat pan 220 may rotate toward and away from backrest 222. For instance, seat pan 220 may be configured to rotate along the axis perpendicular to the first and second walls 204a, 204b such that a user (e.g., a flight attendant) can sit on the seat pan 220 when extended at least substantially perpendicularly from the housing 202. Seat pan 220, backrest 222, and/or headrest 218 may be partially stored within housing 202 of seat 200.

[0038] In accordance with various embodiments, seat 200 may include a lower storage compartment 224. Lower storage compartment 224 may be located proximate foot end 205 of housing 202. A housing door 226 may be located over lower storage compartment 224. Door 226 may be pivotably coupled to housing 202. For instance, a release handle 228 may be disposed in door 226. Release handle 228 may be configured to release the door 226, thereby allowing door 226 to pivot away from housing 202.

[0039] Seat 200 may further include a drop-down tray assembly 230. The drop-down tray assembly 230 may be configured to rotate with the headrest 218. For instance, the drop-down tray assembly 230 may be coupled to the upper portion 210 via the hinge 219 such that the drop-down tray assembly 230 may be configured to rotate along the axis perpendicular to the first and second walls 204a, 204b such that a user (e.g., a flight attendant) can use the drop-down tray assembly 230 as a platform when extended out at least substantially perpendicularly from the housing 202 (e.g., see FIG. 2C). For instance, the drop-down tray assembly 230 as the platform may be used as a workstation, a bar, table, serving table, tray, etc. as described further herein wherein the headrest 218 is configured to provide additional support to the drop-down tray assembly 230. In various embodiments, the drop-down tray assembly 230 may be coupled to the headrest 118. In various embodiments, the drop-down tray assembly 230 may be configured to rotate independently from headrest 218. For instance, the drop-down tray assembly 230 may be rotatably coupled to the hinge 219 but configured to rotate with the headrest 218 (e.g., the user may choose to only extend the headrest 218). In various embodiments, the drop-down tray assembly 230 may be coupled to a separate hinge 221.

[0040] The drop-down tray assembly 230 is configured to provide a stand-up (e.g., a standing height) workstation contained within the housing 202. For instance, the drop-down tray assembly 230 may be received and stored within a workstation cavity 232 of the housing 202. When the drop-down tray assembly 230 is positioned in its extended, or deployed, position (e.g., extending perpendicular to the housing 202), the workstation cavity 232 is exposed. The workstation cavity 232 may be configured to house various components of the drop-down tray assembly 230 such as a work surface, tablet holder, work light, charging station, and/or a notebook caddy. For instance, the drop-down tray assembly 230 includes a first surface 234. The first surface 234 may be used as a workstation platform on its own.

[0041] However, referring particularly to FIG. 2D, the drop-down tray assembly 230 may further include a second surface 236. For instance, the first surface 234 may be configured to rotate away from the second surface 236 via a hinge 235 until the first surface 234 is parallel to an axis parallel to the first and second walls 204a, 206a and perpendicular to the second surface 236. Accordingly, the second surface 236 may be used as the workstation platform and the first surface 234 is configured as a back panel. For instance, the drop-down tray assembly 230 a deployed position and with a laptop 238 being positioned thereon. Any appropriate portable computer, tablet, other electronics (e.g., mobile phone), or other articles may be disposed on/supported by the drop-down tray assembly 230 when in its deployed position.

[0042] In various embodiments, a power switch, one or more power sockets or electrical outlets (e.g., USB charging port), and one or more wire holders may be incorporated by the workstation cavity 232. In various embodiments, the workstation cavity 232 may include built in inductive charging (e.g., Qi/MagSafe). The wire holder(s) are for wire management and are of a configuration that encompasses clips (e.g., U-shaped; J-shaped), or any appropriate retention structure for retaining a cord, cable, or the like, such as a power cable for a laptop, a tablet, or the like. The workstation cavity 232 may further include a network cable and/or network port 239 to couple to the laptop 238.

[0043] The drop-down tray assembly 230 may further include a support arm 240. The support arm 240 is configured to rotate via hinge 219. Once rotated to the deployed position of the drop-down tray assembly 230, the support arm 240 may be configured to further rotate relative to the second surface 236 such that the support arm 240 is perpendicular to the second surface 236, opposite the first surface 234 (e.g., see FIG. 2D).

[0044] In various embodiments, the drop-down tray assembly 230 may include one or more latches (not shown) for locking the drop-down tray assembly 230 in its stowed position (e.g., see FIG. 2A). When the latch is disposed in an unlocked configuration, movement of the drop-down tray assembly 230 may be initiated toward its deployed position.

[0045] Referring now to FIGS. 3A-3B and 4A-4B, in various embodiments, seat 200 may be a first seat 200. As such, aircraft 100 may include a second seat 300. However, in various embodiments, as described herein, the second seat 300 may be the only seat of aircraft 100. The second seat 300 may comprise a second housing 302 having first and second walls 304a, 304b. In various embodiments, housing 202 may be a 14.0 ft-20.0 ft (e.g., 4.27 m-6.10 m) monument. Further, second housing 302 comprises an upper portion 306 and a lower portion 308. The second housing 302 may comprise a headrest 310, a seat pan 312, and a backrest 314. The second seat 300 may be structured similarly to the first seat 200 with respect to the headrest 310, the seat pan 312, and the backrest 314 such that the headrest 310, the seat pan 312, and the backrest 314 correspond to the headrest 218, the seat pan 220, and the backrest 222, respectively, of seat 200. For instance, the upper portion 306 comprises the headrest 310 and the lower portion 308 comprises the seat pan 312 and the backrest 314 such that the headrest 310 functions discretely from the seat pan 312 and the backrest 314.

[0046] The lower portion 308 is defined by a panel 316. Panel 316 may be configured to rotate relative to the second housing 302 and independently from the upper portion 306 and independently from the seat pan 312. Panel 316 may be rotatably coupled to at least one of the first and second walls 304a, 304b. For instance, the panel 316 may be hinged via a hinge 319 to the first wall 304a such that the panel rotates along an axis parallel to the first wall 304a.

[0047] FIG. 3A illustrates the panel 316 in an open position, in accordance with various embodiments. As mentioned herein, second housing 302 may be secured to an aircraft structure, such as a floor or a wall a galley 301 of an aircraft. Outboard closest access is often blocked by galleys, furniture, seats or other monuments. Further, payload may be limited to small items and access is only from the aisle or a small door. However, in the embodiments described herein, opening panel 316 exposes a volume 318 (e.g., a cavity) within second housing 302. In various embodiments, the volume 318 is configured (e.g., sized and shaped) to receive various items for storage. For instance, the volume 318 may store items such as wheelchairs (e.g., see FIGS. 3A-3B), bar carts (e.g., see FIGS. 4A-4B), etc. By mounting the panel 316 to the second housing 302 and incorporating the storage into the seat 300, the volume 318 (e.g., closet/storage space) can be accessed from an emergency exit cross-aisle.

[0048] Panel 316 includes an interior (or first) wall 320 and an exterior (or second) wall 322. When panel 316 is in the closed position, as shown in FIG. 3B, interior wall 320 is oriented toward volume 318 (i.e., toward an interior of second housing 302) and exterior wall 322 is oriented away from volume 318 (i.e., away from an interior of second housing 302). For instance, the seat pan 312 and the backrest 314 are coupled to the exterior wall 322 and are configured to move with the panel 316. In accordance with various embodiments, seat 300 includes a latch assembly 324 configured to secure panel 316 to second housing 302. Latch assembly 324 may include a latch open indicator 326. In various embodiments, panel 316 may be a 16G load-rated door. In various embodiments, with reference particularly to FIG. 4B, the seat 300 may include a ramp 328. The ramp 328 may be an angled edge extrusion such that the bar cart is able to be rolled into the volume 318 smoothly.

[0049] Referring now to FIG. 5, in various embodiments, the second housing 302 may be a bar unit 330. For instance, the upper portion 306 may comprise the bar unit 330. The bar unit 330 may include at least one window 332 (e.g., a glass door, a sliding glass door, fixed window) configured to provide visual and/or physical access to beverages stored within the second housing 302. In various embodiments, the second housing includes a drop-down tray assembly 334. Drop-down tray assembly 334 may be configured similarly to the drop-down tray assembly 230. For instance, the drop-down tray assembly 334 may include a first surface 336, a second surface 338, and a support arm 339 corresponding to the first surface 234, the second surface 236, and the support arm 240. Accordingly, in a deployed position, the drop-down tray assembly 334 may expose the at least one window 332.

[0050] Referring now to FIGS. 6A-6B, the aircraft 100 may include both the first seat 200 and the second seat 300. In various embodiments, the second seat 300 may be positioned opposite the first seat 200. In other words, the first seat 200 and the second seat 300 are in confronting relation, thus creating an aisleway (e.g., an exit zone). For instance, the first seat 200 and the second seat 300 may be positioned on either side of an exit door, and may open facing each other (e.g., the headrest 218 and the headrest 310 are configured to rotate away from their respective housings and toward each other). In flight, when the exit is not needed to be accessible, the drop-down tray assemblies 230, 334 may be deployed to form a social area (e.g., place a beverage on the drop-down tray assemblies 230, 334) and/or workstations.

[0051] In various embodiments, the drop-down tray 334 may comprise an at least one extension 340. The extension 340 may be configured to slide out from the drop-down tray 334. For instance, the at least one extension 340 may include a first extension 340a and a second extension 340b. The first extension 340a may be configured to extend from and parallel to the first surface 336. The second extension 340b may be configured to extend from and parallel to the second surface 338. Accordingly, the at least one extension 340 may fill in a gap between the drop-down tray assemblies 230, 334. In various embodiments, the drop-down tray assembly 230 may comprise the at least one extension.

[0052] Referring now to FIGS. 7A-7C, the first seat 200 may include a slide-out table 242. For instance, due to the multi-piece configuration of the upper portion 210 and the lower portion 212 and the corresponding gap in between the headrest 218 and seat pan 220/backrest 222, the slide-out table 242 may be disposed in the housing 202 and configured to slide out from the housing 202 underneath the headrest 218. The slide-out table 242 may be a smaller option to the drop-down tray assembly 230. For instance, the slide-out table 242 may be approximately 12.0 in18.0 in (e.g., 30.48 cm45.72 cm). Additionally, the upper portion 210 may include a door 244 such that the headrest 218 is coupled to the door 244. The door 244 may be configured to rotate along the axis parallel to the first and second walls 204a, 204b. Further, the second seat 300 may include a slide-out table 342. Similar to the slide-out table 242, the slide-out table 342 may be disposed in the second housing 302 and configured to slide out from the second housing 302 underneath the headrest 310. Additionally, the upper portion 306 may include a door 344 such that the headrest 310 is coupled to the door 344. The door 344 may be configured to rotate along the axis parallel to the first and second walls 304a, 306a. Accordingly, the door 344 may be configured to expose the at least one window 332. The flight attendant may then access the beverages and use the slide-out table 342 as a prep station, for instance.

[0053] In various embodiments, the components described herein with reference to each of the first seat 200 and the second seat 300 may be modular and thus various combinations may be formed. For instance, as described herein, the aircraft 100 may include the first seat 200, the second seat 300, or both. In various embodiments, the aircraft 100 may include more than one first seat 200. In various embodiments, the aircraft 100 may include more than one second seat 300 (e.g., see FIGS. 7A-7B). In various embodiments, one second seat 300 may include the bar unit 330 while the second seat 300 does not. In various embodiments, one seat may (e.g., the first seat 200 and/or the second seat 300) may include a drop-down tray assembly (e.g., the drop-down tray assemblies 230, 334) while the other includes only a slide-out table (e.g., slide-out tables 242, 342). In various embodiments, the first seat 200 and/or the second seat 300 includes both the drop-down tray assembly and the slide-out table).

[0054] As described herein, the multi-piece CAS system allow heightened flexibility of inflight configurations and functions. Further, the multi-piece CAS system provides lower cost and lower weight due to decreased parts and failure modes, while achieving high versatility. The multi-piece CAS also provides a configuration wherein the exit door is never completely locked, thus increasing safety in an emergency.
