The present disclosure generally relates to a flexible aircraft privacy door and method of using the same within an aircraft.
Passenger privacy can be a problem in aircraft and other vehicles. In certain aircraft cabins—for instance in business class and/or first class or other premium classes—passengers are increasingly demanding privacy from other passengers sitting in close proximity to them. To satisfy such passenger needs, airlines are forced to afford larger, more spacious suites that are equipped to provide privacy from other passengers within the aircraft through various panels, doors and other cabin structures that separate the passenger in the suite from the rest of the cabin.
The multi-class cabin arrangements in certain aircraft further require specific class dividers and panels in order to efficiently separate the passengers from each other, driven primarily by passenger comfort. A feature that is particularly true for aircraft seating, especially premium seating such as first or business class seating, exists in which it may be desirable to provide seated passengers with privacy not only with respect to neighboring passengers but also with respect to an adjacent aisle. Many airlines are seeking to provide seats with privacy doors or screens, and aircraft interior designers have been tasked with making such privacy doors or screens as safe and efficient as possible.
Luxury passenger cabins are often fitted with private suites that include facilities for sitting, reclining, sleeping, dining and/or other activities. In addition, approaches to address privacy door designs require complex mechanisms in order to meet regulatory requirements for emergency egress during flight operations. The rules are intended to ensure that any evacuation is not degraded due to the presence of any privacy doors or privacy panels. Aircraft cabin suites are generally equipped with conventional privacy screens or doors that allow the screens or doors to be opened or closed as desired by the passenger. However, due to the limited space and other design limitations/configurations and passenger regulatory requirements, most of the privacy doors or screens currently available in the market are rigid and thereby lack any functionality with regard to flexibility.
Prior art configurations of privacy doors comprise panels or other rigid structures which are fixed and prone to getting jammed during flight operation. Further, such conventional panels are not configured for easy and efficient opening and closing for passenger comfort and privacy. Rather, prior art panels, doors and other cabin structures are generally required to have features to allow the passenger emergency egress from the seat without any flexibility to offer during emergency egress from the cabin suite. In order to meet safety regulations, any door positioned between the passenger and the aisle is thus desirably designed and configured such that if the primary means of egress is disabled, a secondary means of egress is provided. The general intent is to ensure that a passenger does not become trapped within the enclosed suite or mini suite, without a safe alternate egress route. Climbing over a passenger seat shell is generally not considered a safe secondary exit route. All of the foregoing issues further limit design options and/or configurations for aircraft privacy doors and panels.
In addition, there are only a few currently available examples of features making a door panel being removable (either partially or fully) and the door panel being hinged to the backshell of an airplane seat. Generally, any enclosed suite or mini suite—the term of art used to refer to a passenger seating area or space that has a privacy feature positioned between the seat and the aisle or other common area—has an enclosure with a secondary opening feature (or secondary egress) in the event that the primary opening feature (primary egress) fails in a deployed or closed position.
Even if some progress were made in designing and building flexibility in the privacy doors, they would still lack the robustness and structural reliability that is required to operate smoothly within an aircraft cabin. Certain existing privacy doors/panels—for example the Safran Versa door—end up providing too much flexibility without any structural integrity or robustness (nothing more than a cloth held taut across the opening via supports at both ends).
In sum, currently available designs and configurations of privacy doors lack the needed flexibility, maneuverability and adaptability for passenger privacy and access. Therefore, there is clearly a market need for an improved flexible aircraft privacy door for use on airplane seating products—specifically designed and configured with semirigid material overcoming the disadvantages and shortcomings of the conventional prior art privacy doors—a novel and unique flexible aircraft privacy door that can provide passenger privacy while making the overall flying experience for a passenger much more pleasurable.
The present disclosure is directed to an apparatus and method comprising an improved flexible aircraft privacy door. More particularly, the present disclosure is directed to a novel and uniquely configured flexible privacy door that provides significant performance and efficiency improvement from currently available prior art privacy screens or doors—providing privacy to a passenger while overcoming shortcomings and disadvantages of conventional aircraft privacy doors and screens.
Embodiments disclosed in the present disclosure provide a flexible aircraft privacy door and method of using the same.
In an aspect of the present disclosure, an apparatus and associated methods related to a flexible aircraft privacy door are provided—a flexible privacy door attached to the backshell of an airplane seat—shaped and configured to bend and return to its original shape when a certain minimal amount of force is applied to the privacy door. The flexible privacy door assembly for an aircraft cabin environment comprises a flexible privacy door having a first edge (e.g., leading edge) located at a distal end from a second edge (e.g. trailing edge)—the flexible privacy door coupled to a backshell of an airplane seat and moveable between a first position and a second position. In the depicted embodiment, (a) the first edge and a portion of a length of the door are moveable out of plane of an opening by way of force against the door in the second position and (b) a portion of a length of the privacy door in the second position is flexibly bendable out of the plane of an airplane seat entrance up to a certain pre-determined bending distance in order to allow at least one person to pass through the opening for ingress and/or egress during flight operations.
In another aspect of the present disclosure, the flexible privacy door can be installed proximate to a passenger seat and/or suite in an aircraft cabin and configured to partially or fully obstruct the view from outside observers into the area around the passenger seat and/or suite. The flexible privacy door comprises a first edge and a second edge located at a distal end from the first edge and wherein the door is positioned along the side of a respective seat/suite interrupting any unobstructed view of a passenger sitting inside the seat/suite as well as preventing other passengers from seeing inside the seat/suite, thereby enhancing the feeling of privacy to a passenger. The flexible privacy door disclosed herein is further configured to have a minimal or almost no impact on the existing aircraft seat structures and can be easily attached to backshells of the airplane seats currently installed in many aircraft around the world.
As further disclosed in the detailed description and illustrated in the accompanying drawings, the flexible privacy door is movable and slidable in and out of or within a wall pocket in a fore-and-aft direction between an open position (the fully retracted position leaving an opening between spaced structures of a passenger seat/suite) and a closed position (the fully deployed position) between the spaced structures of a passenger seat/suite. Further, the flexible privacy door is designed and shaped to hold its shape without external support during normal usage, the semirigid material used for the door further providing the structural integrity to hold its shape as a privacy door without any additional external support structure.
In yet another aspect of the present disclosure, the use of certain materials—by way of example and not of limitation—certain types of semirigid materials having a predetermined modulus of elasticity provides the required structural integrity and flexibility to the privacy door for passenger ingress and/or egress. For instance, the flexible privacy door can bend out of the plane of the seat/suite entrance into or out of the seat/suite up to a certain bending distance, allowing a passenger to pass through the opening for ingress/egress while providing the needed flexibility, maneuverability and adaptability for passenger privacy and access.
In another aspect of the present disclosure, a method of establishing a flexible privacy door for a passenger cabin environment is provided, the method comprising the steps of: (1) coupling the privacy door having a first edge located at a distal end from a second edge to a backshell of an airplane seat such that the door is moveable between a first position and a second position; (2) moving the first edge and a portion of a length of the door out of plane of an opening by way of force against the door in the second position; (3) flexibly bending a portion of a length of the privacy door in the second position out of the plane of an airplane seat entrance up to a certain pre-determined bending distance; and (4) allowing at least one person to pass through the opening for ingress and/or egress during flight operations.
The various embodiments of the improved flexible privacy door described herein can be configured to provide both normal and emergency-use operations of the privacy door in order to provide maximum privacy and ease of use to the passenger while maintaining emergency ingress/egress paths as well as sight lines for flight crew personnel to have a clear view of the passengers sitting in the passenger seats or suites within the aircraft cabin. Many other benefits of the embodiments described herein include providing a door that is configurable for various types of aircraft cabin and suite frameworks and improving manufacturing and installation efficiency while providing value-added cost benefits to aircraft manufacturers and airline operators.
The flexible privacy door can be designed and built in order to ensure that it can be configured to work within a certain predefined envelop size for a certain aircraft seating arrangement. The door can be manufactured using the standard TenCate Layup process and structurally embedded with metal blocks or can be manufactured using other equivalent materials and processes. Further, the flexible privacy door disclosed herein can be used with standard backshell designs having a top backshell trim.
In addition, the flexible privacy door will be primarily operable in two positions: (1) Taxi, Take-Off and Landing (TTOL); and (2) Deployed. The privacy door in the TTOL position can be configured with dual latching and a detent and in the deployed position can also be configured with a detent—the privacy door configured to go inside a cavity (or wall pocket) to address any potential misalignment issues and help reduce any related abuse load. Finally, as further described below, the flexibility of the privacy door allows a passenger emergency egress from the seat/suite without performing any additional actions; the passenger can simply push through the door with minimal effort during emergencies, allowing a simpler and more efficient design of the flexible privacy door while easing regulatory requirements for passenger aircraft.
