Patent Application
20230331389
The present application is a divisional of U.S. Patent Publication No. 2021/0061474, published Mar. 4, 2021, which is incorporated herein by reference in the entirety.
Several components within an aircraft cabin are used only when the aircraft is in taxi, takeoff, or landing phases (TTL). Aircraft cabin attendant seats, also referred to as jump seats, are one such TTL component, as the cabin attendant typically utilizes aircraft cabin attendant seats only under TTL phases. These seats are typically placed in either the forward section or rear section of the aircraft (e.g., adjacent to a galley or cockpit) as well near exit doors.
Because aircraft cabin attendant seats are not used during flight, they have been designed to be minimized during flight. This strategy allows for more efficient use of space in the cabin. For instance, a conventional seat for an aircraft flight attendant includes a pulldown seat that may be built into a bulkhead facing away from passenger seating. During TTL phase, the seat may be pulled down into a seating position and used. Once in flight, the seat may be folded back into the bulkhead wall, and the space originally occupied by the sitting flight attendant may now be used for other flight activities (e.g., assisting a passenger or setting up a drink cart). Reducing the three-dimensional space taken up by the aircraft cabin attendant seat may also increase the ability of aircraft staff and passengers to move around the cabin, resulting in increased work flow, morale, and passenger safety.
In today's airline industry, aircraft design continues to push forward to more efficient use of space (e.g., increased passenger seating). Unfortunately, increasing passenger seating may reduce the space available to other items in the aircraft cabin, including lavatories and aircraft attendant seats. Complicating matters further, government agencies (e.g., the Federal Aviation Administration or the European Aviation Safety Agency) have promulgated regulations that mandate minimal dimensions for many aspects of aircraft cabins, including widths of emergency exit passageways. Accordingly, there is a need for a solution that provides space for increasing passenger number or passenger space while maintaining seating for aircraft attendants and meeting regulations related to exit passageway dimensions.
An aircraft cabin attendant seat is disclosed. In one or more embodiments, the aircraft cabin attendant seat includes a support element extending from a cabin floor. The support element includes a bottom support element portion that is attached to the cabin floor. The support element further includes a top support element portion. The support element also includes a coupler that connects the bottom support element portion to the top support element portion. In some embodiments, the coupler is configured to allow the top support element portion to rotate along a horizontal axis. The aircraft cabin attendant seat further includes a backrest that is coupled to the top support element portion. The aircraft cabin attendant seat also includes a headrest that is coupled to the top support element portion and disposed above the backrest.

This Summary is provided solely as an introduction to subject matter that is fully described in the Detailed Description and Drawings. The Summary should not be considered to describe essential features nor be used to determine the scope of the Claims. Moreover, it is to be understood that both the foregoing Summary and the following Detailed Description are example and explanatory only and are not necessarily restrictive of the subject matter claimed.
The detailed description is described with reference to the accompanying figures. The use of the same reference numbers in different instances in the description and the figures may indicate similar or identical items. Various embodiments or examples (“examples”) of the present disclosure are disclosed in the following detailed description and the accompanying drawings. The drawings are not necessarily to scale. In general, operations of disclosed processes may be performed in an arbitrary order, unless otherwise provided in the claims. In the drawings:
Before explaining one or more embodiments of the disclosure in detail, it is to be understood that the embodiments are not limited in their application to the details of construction and the arrangement of the components or steps or methodologies set forth in the following description or illustrated in the drawings. In the following detailed description of embodiments, numerous specific details may be set forth in order to provide a more thorough understanding of the disclosure. However, it will be apparent to one of ordinary skill in the art having the benefit of the instant disclosure that the embodiments disclosed herein may be practiced without some of these specific details. In other instances, well-known features may not be described in detail to avoid unnecessarily complicating the instant disclosure.
As used herein a letter following a reference numeral is intended to reference an embodiment of the feature or element that may be similar, but not necessarily identical, to a previously described element or feature bearing the same reference numeral (e.g., 1, 1a, 1b). Such shorthand notations are used for purposes of convenience only and should not be construed to limit the disclosure in any way unless expressly stated to the contrary.
Further, unless expressly stated to the contrary, “or” refers to an inclusive or and not to an exclusive or. For example, a condition A or B is satisfied by any one of the following: A is true (or present) and B is false (or not present), A is false (or not present) and B is true (or present), and both A and B are true (or present).
In addition, use of “a” or “an” may be employed to describe elements and components of embodiments disclosed herein. This is done merely for convenience and “a” and “an” are intended to include “one” or “at least one,” and the singular also includes the plural unless it is obvious that it is meant otherwise.
Finally, as used herein any reference to “one embodiment” or “some embodiments” means that a particular element, feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment disclosed herein. The appearances of the phrase “in some embodiments” in various places in the specification are not necessarily all referring to the same embodiment, and embodiments may include one or more of the features expressly described or inherently present herein, or any combination of or sub-combination of two or more such features, along with any other features which may not necessarily be expressly described or inherently present in the instant disclosure.
Broadly, embodiments of the disclosure are directed to a configurable aircraft cabin attendant seat. Aircraft cabin attendant seats are typically placed in the forward or rear sections of the aircraft cabin, as well as near exit doors. Because aircraft cabin attendant seats are not used when the aircraft has attained cruising altitude, many such seats are designed to be folded away (e.g., having a seat lifted up if the seat is attached to a bulkhead), allowing more space for attendants and passengers to move around the cabin, such as in the assist space (e.g., an unobstructed area where attendants may assist evacuees), increasing work efficiency and safety. However, simple seat folding designs often require bulkheads that themselves constrict space to attendants and passengers. Furthermore, a seat folded into a bulkhead would prevent that surface area of the bulkhead to be further utilized (e.g., for storage or supporting an appliance. Consequentially, there is a need for an aircraft cabin attendant seat that allows for more efficient use of space than allowed previously.
The aircraft cabin attendant seat 100 further includes a backrest 150, attached to the top support element portion 130 of the support element 110. The backrest 150 provides support and comfort to the back of a flight attendant while sitting in the aircraft cabin attendant seat 100. The backrest 150 may be configured as a contoured or noncontoured surface of the top support element portion. The backrest 150 may further include a cushion.
The aircraft cabin attendant seat 100 further includes a headrest 160, attached to the top support element portion 130 of the support element 110. The headrest 160 provides support and comfort to the head of a flight attendant while sitting in the aircraft cabin attendant seat 100. The headrest 160 may be configured as a contoured or noncontoured surface of the top support element portion. The headrest 160 may further include a cushion.
The aircraft cabin attendant seat further includes a seating portion 170. The seating portion 170 is coupled to the top support element portion 130 of the support element 110. The seating portion 170 further includes a seat 180 and a hinge 190. The hinge 190 couples the seat 180 to the top support element portion 130. The hinge 190 permits the seat 180 to extend substantially perpendicular from the support element 110, where seat 180 may support the weight of a flight attendant. When the seat 180 is not in use, the hinge 190 permits the seat to be tilted upwards along a horizontal axis until the seat rests adjacent and substantially parallel to the backrest 150.
In some embodiments, the aircraft cabin attendant seat 100 may be configured to rotate along a vertical axis (although not shown). For instance, by rotating along a vertical axis, the aircraft cabin attendant seat 100 (e.g., in a storage configuration) may be disposed adjacent and parallel to an armrest (e.g., or used as an armrest) of a passenger seat, a cabin wall or bulkhead. In this manner rotating the aircraft cabin assistant seat along a vertical axis frees up space that may be used as an assist space or other working space. In a similar manner, the aircraft cabin attendant seat 100 (e.g., in a storage configuration) may be disposed adjacent and parallel to a lateral side of the passenger seat 105. In another instance, the aircraft cabin attendant seat may be configured to rotate from the footwell of a passenger seat 105 to a position outside of the footwell of the aircraft passenger seat 105, allowing a passenger full use of the footwell in-flight. In some embodiments, the aircraft cabin attendant seat 100 may slide along a first direction (e.g., along a guided track) in order to free up cabin space (e.g., assist space) or to give the passenger more room (e.g., legroom, or allowing the aircraft passenger seat 105 to further recline. In some embodiments, the aircraft cabin assistant seat may be configured to both rotate on a vertical axis and slide in a first direction. Therefore, the above description should not be interpreted as a limitation of the present disclosure, but merely an illustration.
In some embodiments, the aircraft cabin attendant seat 100 is disposed immediately adjacent to or within the aft row back shell of a passenger seat 105. For instance, during TTL phase, the back shell of a passenger seat 105 may abut to the rear of the support element 110 of the aircraft cabin attendant seat 100. When in-flight, the support element 110 may be moved out of the way of the back shell, allowing the passenger seat 105 to recline. In another instance, the back shell of the passenger seat and the rear of the support element 110 of the aircraft cabin attendant seat 100 are coupled together as one unit, allowing both passenger and attendant to sit within their respective seats at TTL phase. In flight, the attendant is no longer sitting in the aircraft cabin attendant seat 100, allowing the passenger to recline the passenger seat 105.
In some embodiments, the aircraft cabin attendant seat 100 may be further configured to be integrated into an element of the passenger seat 105 and/or aircraft cabin. For instance, the aircraft cabin attendant seat 100 may integrate into a bulkhead or partition of the aircraft cabin (e.g., the aircraft cabin attendant seat may act as a partition in itself). Upon leaving TTL phase, the aircraft cabin attendant seat 100 may be further configured to move (e.g., rotate, or move along a track), allowing more space for passenger and/or attendant. In another instance, the aircraft cabin attendant seat 100 may integrate into passenger seat 105 (e.g., configured in a back-to-back configuration, allowing both passenger and attendant to sit at the same time). In another instance, the aircraft cabin attendant seat 100 may integrate into an element within the passenger seating area, such as a partition that defines the footwell of the passenger seating area during TTL. In this instance, upon leaving TTL phase, the aircraft cabin attendant seat 100 may be further configured to move (e.g., rotate, or move along a track), allowing more legroom for the passenger.
In some embodiments, the aircraft cabin attendant seat 100 may be configured to seat two or more flight attendants. For instance, the aircraft cabin attendant seat 100 may have individual top support element portions, but have a single shared seat (e.g., a bench). In another instance, the aircraft cabin seat may have both shared top and bottom support element portions. It should be noted that the aircraft cabin attendant seat may have any combination of shared components for two or more passengers. Therefore, the above description should not be interpreted as a limitation of the present disclosure, but merely as an illustration.
The aircraft cabin attendant seat 200 further includes a backrest 150. The backrest 150 is attached to one or more subsections of the support element 110. In some embodiments the backrest 150 is attached to two subsections that are further coupled by a coupler 140 (e.g., the dotted horizontal line in
The aircraft cabin attendant seat 200 further includes a headrest 160 disposed above the backrest 150. In some embodiments, the headrest 160 is attached to a subsection of the support element 110. In some embodiments, the subsection of the support element 110 attached to the headrest 160 is coupled to a subsection of the support element 110 attached to the backrest 150, via a hinge or sliding track, permitting the subsections to fold and/or slide upon each other into a compact structure. The headrest 160 may be of any size or shape of a headrest 160 known in the art to be used in an aircraft cabin attendant seat 200 (e.g., an isosceles trapezoid or a square). In some embodiments, the headrest 160 and the backrest 150 are attached to the same subsection of the support element 110.
The aircraft cabin attendant seat 200 further includes a seating portion 170. The seating portion contains a seat 180 and a hinge 190 (although not shown). While in the TTL phase, the seating portion 170 is configured to have the seat 180 fully extended for use as a seat, as shown in
In some embodiments, the subsections of the aircraft cabin attendant seat 200 are coupled via a set of hinges, allowing the aircraft cabin attendant seat to fold into a compact form 215. Alternatively, in some embodiments, the subsections of the aircraft cabin attendant seat are coupled via a sliding track mechanism, allowing the subsections of the aircraft cabin attendant seat 200 to slide adjacent to each other into a compact form 215. Alternatively, the subsections may be positioned in a telescopic arrangement, allowing at least one subsection to fit inside of another subsection to product a compact form. It should be noted that any combination of the above compacting technologies, or other compacting technologies not listed here can be used to create a compact form 215 of the aircraft cabin attendant seat 200. Therefore, the above description should not be interpreted as a limitation of the present disclosure, but merely an illustration.
The aircraft cabin attendant seat may be attached to the cabin floor of the aircraft via a cabin floor coupler 220. In some embodiments, the cabin floor coupler is configured to allow the aircraft cabin attendant seat 200 to rotate along a vertical axis. Upon rotating along a vertical axis, the aircraft cabin attendant seat (e.g., either in compact form 215 or non-compact form) may align adjacent to and parallel to a wall, bulkhead, cabin seat, or armrest of a cabin seat. For instance, an aircraft cabin attendant seat 200 that disposed on the end of a row of passenger seats 205 may be configured to collapse into a compact form 215, then rotate along a vertical axis (e.g., along one corner of the aircraft cabin attendant seat 200) so that the compact form 215 of the aircraft cabin assistant seat 200 is adjacent and parallel to the armrest of a passenger seat 105 and/or the lateral side of the passenger seat (e.g., as in
In some embodiments, the compact form 215 of the aircraft cabin assistant seat 200 may be configured to operate as a pedestal or table. For instance, the compact form 215 may be configured to hold refreshments, literature (e.g., magazines or advertisements), or other objects during flight. In another instance, the compact form may be configured to operate as a bench (e.g., for a passenger waiting to use the lavatory). The compact form 215 of the aircraft cabin assistant seat 200 may be configured for other uses not listed here. Therefore, the above description should not be interpreted as a limitation of the present disclosure, but merely an illustration.
In some embodiments, the compact form 215 of the aircraft cabin assistant seat 200 may be further configured to fold onto the cabin floor. For instance, once the aircraft cabin assistant seat 200 has collapsed into a compact form 215, the cabin floor coupler 220 may be configured to allow the compact form 215 to translate to a position adjacent and parallel to the cabin floor (e.g., to lay flat on the cabin floor). Once positioned onto the floor, the compact form 215 of the aircraft cabin assistant seat 200 may be further configured to slide or move upon a vertical axis to create more usable space in the assist space (e.g., by sliding and/or swinging underneath a passenger seat). In some embodiments, the compact form 215 of the aircraft cabin assistant seat 200 may fold into a recess of the cabin floor. In some embodiments, the compact form 215 of the aircraft cabin assistant seat 200 may be readily removed in-flight (e.g., via a quick detach/reattach mechanism) and stored.
In some embodiments, the aircraft cabin attendant seat 200 may be configured to seat two or more flight attendants. For instance, the aircraft cabin attendant seat 200 may have individual backrest and headrest portions, but have a single shared seat (e.g., a bench). In another instance, the aircraft cabin attendant seat 200 may have both shared backrest, headrest and seat portions. It should be noted that the aircraft cabin attendant seat may have any combination of shared components for two or more passengers. Therefore, the above description should not be interpreted as a limitation of the present disclosure, but merely as an illustration.
In some embodiments, the aircraft cabin attendant seat 200 may be further configured to be integrated into an element of the passenger seat 105 and/or aircraft cabin. For instance, the aircraft cabin attendant seat 200 may integrate into a bulkhead or partition of the aircraft cabin (e.g., the aircraft cabin attendant seat may act as a partition in itself). Upon leaving TTL phase, the aircraft cabin attendant seat 200 may be further configured to move (e.g., rotate, or move along a track), allowing more space for passenger and/or attendant. In another instance, the aircraft cabin attendant seat 200 may integrate into passenger seat 105 (e.g., configured in a back-to-back configuration, allowing both passenger and attendant to sit at the same time). In another instance, the aircraft cabin attendant seat 200 may integrate into an element within the passenger seating area, such as a partition that defines the footwell of the passenger seating area during TTL. In this instance, upon leaving TTL phase, the aircraft cabin attendant seat 200 may be further configured to move (e.g., rotate, or move along a track), allowing more legroom for the passenger.
It should be noted that the aircraft cabin attendant seat 100, 200 may be configured to include safety harnesses (e.g., seat belts), pockets, audio-visual user interface devices, or any other components known in the art to be associated with an aircraft cabin attendant seat 100, 200. Therefore, the description herein should not be a limitation of the present disclosure, but merely an interpretation.
Although inventive concepts have been described with reference to the embodiments illustrated in the attached drawing figures, equivalents may be employed and substitutions made herein without departing from the scope of the claims.
