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.

<FIG> in general illustrate a modular seatback cover attachment system for an aircraft seat, in accordance with one or more embodiments of the disclosure.

Seats may include some combination of components such as, but not limited to, a seat pan dress cover, a seatback dress cover, a seat pan cushion, a seatback cushion, a seat pan support system, a seatback support system, and a seatback bezel. In select seat designs, the seatback dress cover alone may be composed of numerous pieces, where each piece is then coupled together to form the seatback dress cover. After the individual components are assembled, the seat components may be coupled together with one or more attachment assemblies to form the aircraft seat. For example, the seatback dress cover may be coupled to the seatback bezel to form the seatback of the aircraft seat. For instance, the seatback dress cover may be tucked within a gap between the seatback bezel and the seatback frame to retain the seatback dress cover within the gap. Often the gap between the seatback bezel and the seatback frame is narrow, which makes tucking the seatback dress cover in the narrow gap difficult. Further, the gap between the seatback bezel and the seatback frame may be wide, such that the seatback dress cover is not retained within the gap. As such, this method of attachment results in the seatback dress cover from becoming disengaged or fraying at the edges due to variation in the size of the gap between the seatback and the bezel, the dress cover hem thickness/type, and the like.

Further, the seatback cover may be subjected to stress, strain, dirt or other mess such as airsickness, contraband, or the like resulting in damage of the seatback cover. After a period of time and/or a particular type of wear factor occurring, the seatback cover may need to be removed for cleaning and/or replacement. However, removing the seatback cover may require tools and be labor/time intensive. The removal and re-installation process for the seatback cover should be quick, inexpensive, and not labor intensive. For example, the seatback cover attachment system should be quickly dismantled and put together without incurring considerable labor costs and without requiring special tools.

In addition, in select industries the build of the seat (and any included components within the build) may be required to meet guidelines and/or standards. For example, aircraft seats may be required to meet aviation guidelines and/or standards. For instance, the select aircraft seats may need to be configured in accordance with aviation guidelines and/or standards put forth by, but not limited to, the Federal Aviation Administration (FAA), the European Aviation Safety Agency (EASA) or any other flight certification agency or organization; the American National Standards Institute (ANSI), Aeronautical Radio, Incorporated (ARINC), or any other standards setting organization or company; the Radio Technical Commission for Aeronautics (RTCA) or any other guidelines agency or organization; or the like. Seatback cover attachment systems may present difficulties such as, but not limited to, failing to meet load requirements (e.g., <NUM> static load requirements or <NUM> dynamic load requirements), burn requirements, or the like as set forth by the FAA in <NUM> C. Part <NUM>, AIRWORTHINESS STANDARDS: TRANSPORT CATEGORY AIRPLANES).

As such, it would be desirable to provide a modular seatback cover attachment system. The modular seatback cover attachment system should provide a long-term solution for seatback dress cover retention. The modular seatback cover attachment system should be configured to retain various dress covers, whether for a retrofitted aircraft seat or a new aircraft seat design. The modular seatback cover attachment system should eliminate the need to tuck dress covers into a gap between the bezel and the seatback frame. The modular seatback cover attachment system should act as a rub strip on the aircraft seat to take wear (e.g., suitcases, galley carts, or the like). The modular seatback cover attachment system should be quick to install/remove and be tool-less. The modular seatback cover attachment system should be configured in accordance with aviation guidelines and/or standards.

Referring in general to <FIG>, one or more modular seatback cover attachment systems may be integrated within an aircraft seat <NUM> installed within an aircraft cabin. For example, the aircraft seat <NUM> may include, but is not limited to, a business class or first-class passenger seat, an economy-class passenger seat, a crew member seat, or the like. It is noted the terms "aircraft seats" and "passenger seats" may be considered equivalent, for purposes of the disclosure.

The aircraft seat <NUM> may be rotatable about an axis (e.g., swivelable). The aircraft seat <NUM> may be fully positionable between the outer limits of motion as defined by the moveable components of the aircraft seat <NUM>. Where the aircraft seat <NUM> is installed within a passenger compartment, the aircraft seat <NUM> may be fully positionable between the outer limits of motion as defined by one or more passenger compartment monuments of the passenger compartment. It is noted an upright or raised position may be considered a taxi, takeoff, or landing (TTL) position during select stages of flight (though the upright or raised position is not limited to use during the select stages of flight as the TTL position, but also may be used at any point during the flight), for purposes of the present disclosure. In addition, it is noted that any position that does not meet the above-defined requirements of the TTL position may be considered a non-TTL position, for purposes of the present disclosure. Further, it is noted the aircraft seat <NUM> may be actuatable (e.g., translatable and/or rotatable) from the TTL position to a non-TTL position, and/or vice versa. Further, it is noted the aircraft seat <NUM> may be capable of a fully upright or raised position, and that the TTL position may have a more reclined seatback cushion and a more angled upward seat pan cushion as compared to the fully upright or raised position. Therefore, the above description should not be interpreted as a limitation on the present disclosure but merely an illustration.

In general, an aircraft seat <NUM> may be translatable (e.g., trackable or slidable). The aircraft seat <NUM> may be rotatable about an axis cross-wise through the aircraft seat <NUM> into a position including, but not limited to, the upright or raised position, one or more lounge or reclined positions, and a lie-flat or bed position. For example, the aircraft seat <NUM> may transition directly between the upright or raised position and the lie-flat or bed position. By way of another example, it is noted the aircraft seat <NUM> may transition through one or more lounge or reclined positions between the upright or raised position and the lie-flat or bed position. By way of another example, the aircraft seat <NUM> may transition into one or more lounge or reclined positions in a motion separate from the transition between the upright or raised position and the lie-flat or bed position. Therefore, the above description should not be interpreted as a limitation on the scope of the disclosure but merely an illustration.

The aircraft seat <NUM> may include a seatback <NUM>. The aircraft seat <NUM> may include a seat pan <NUM>. The aircraft seat <NUM> may include one or more arms <NUM>. The aircraft seat <NUM> may be coupled to a base <NUM>. The base <NUM> may be couplable to a floor of an aircraft cabin.

The aircraft seat <NUM> may include a seatback dress cover <NUM> including a seatback cushion, where the seatback dress cover <NUM> includes at least one surface configured to conform to a corresponding surface of the seatback frame <NUM>. For example, the seatback <NUM> may include an integrated seatback dress cover and cushion. The seatback dress cover <NUM> may be configured to fit over at least a portion of the seatback cushion. For example, the seatback dress cover <NUM> may be configured to wrap around or otherwise enclose exterior surfaces of the seatback cushion not proximate to the seatback frame <NUM>. The seatback dress cover <NUM> may be configured to attach to the seatback frame <NUM> and/or the cushion. It is noted "seat cover" and "dress cover" may be considered equivalent, for purposes of the disclosure.

The seatback cushion may conform or substantially conform to the seatback frame <NUM>. For example, at least one surface of the seatback cushion may conform to a corresponding surface of the seatback frame <NUM>. By way of another example, components of the seatback frame <NUM> may extend beyond the boundaries of the seatback cushion, such that the at least one surface of the seatback cushion does not fully conform to the corresponding surface of the seatback frame <NUM>. By way of another example, a portion of the seatback cushion may wrap around or otherwise enclose a portion of the seatback frame <NUM>. In general, the seatback frame <NUM> may conform to a portion of a user (e.g., a passenger, a crew member, or the like), and the seatback cushion may similarly conform to the portion of the user due to the seatback cushion conforming to the seatback frame <NUM>.

It is noted the dress cover <NUM> may conform to a portion of a user (e.g., a passenger, a crew member, or the like), or may be independently-shaped. Further, it is noted that the dress cover <NUM> may be formed of any material known in the art including, but not limited to, leather, synthetic leather, fabric, or the like. Additionally, it is noted that the cushion may be formed of any material known in the art including, but not limited to, foam, or the like.

The seatback cushion may be integrated with the dress cover <NUM>. For example, the dress cover <NUM> may be formed of a laminated piece of material integrated with a cushion backing (e.g., a foam backed fabric). It is noted that the cushion may be integrated with the seatback cover <NUM> via any fabrication process (e.g., sewing, or the like) or fastening mechanism (e.g., an adhesive, or the like). In this regard, the modular seatback cover attachment system <NUM> may include an integrated seatback cover and cushion assembly to eliminate the need for an additional seatback cushion component, thereby reducing the assembly time by reducing the number of seatback component parts.

Although embodiments of the disclosure illustrate the dress cover <NUM> including a cushion, it is noted the seatback cushion may be separate from the dress cover <NUM> (e.g., where a cushion layer is separately installed on the aircraft seat <NUM>) and/or the seatback cushion may not be installed on the aircraft seat <NUM>. Therefore, the above description should not be interpreted as a limitation on the present disclosure but merely an illustration.

The seatback <NUM> may include a seatback bezel <NUM> configured to couple to a portion of the seatback frame <NUM>. The seatback bezel <NUM> may include, but is not required to include, a cavity <NUM> for storing a food tray, a storage compartment <NUM>, a charging port or headphone jack <NUM>, and the like. Further, the seatback bezel <NUM> may include an inflight entertainment (IFE) device coupled to a surface of the seatback bezel <NUM> (e.g., in an actuatable or a fixed position).

The cavity <NUM> may be defined by one or more surfaces of the bezel <NUM>. For example, the cavity <NUM> may be configured to store a food tray during TTL or non-TTL stages of flight. For instance, the bezel <NUM> may include a latch configured to securely store the food tray in the stowed position within the cavity <NUM> during TTL or non-TTL stages of flight.

In this regard, the force may be applied to engage the seatback frame <NUM> with the trim cap until the tabs snap into place.

In a step <NUM>, a second trim cap may be coupled to a second portion of the seatback frame. For example, a second trim cap 302b may include a right side trim cap 302b configured to couple to a right side portion 200b of the seatback frame. For instance, a force may be applied to engage the right side trim cap 302b with the right side portion 200b of the seatback frame <NUM> until the attachment system <NUM> interlocks with the seatback frame <NUM>. In this regard, the force may be applied through an application of force on the attachment system <NUM> (e.g., the trim cap) in a specific direction until the attachment system <NUM> (e.g., tabs <NUM>) interlocks with the seatback frame <NUM>. For instance, the force may be applied in an inward direction towards the seatback frame <NUM>. In this regard, the force may be applied to engage the seatback frame <NUM> with the trim cap until the tabs snap into place.

In a step <NUM>, a third trim cap may be coupled to a third portion of the seatback frame. For example, a third trim cap 302c may include a top trim cap 302c configured to couple to a top portion 200c of the seatback frame. For instance, a force may be applied to engage the top trim cap 302c with the top portion 200c of the seatback frame <NUM> until the attachment system <NUM> interlocks with the seatback frame <NUM>. In this regard, the force may be applied through an application of force on the attachment system <NUM> (e.g., the trim cap) in a specific direction until the attachment system <NUM> (e.g., tabs <NUM>) interlocks with the seatback frame <NUM>. For instance, the force may be applied in a downward direction towards the seatback frame <NUM>. In this regard, the force may be applied to engage the seatback frame <NUM> with the trim cap until the tabs snap into place.

The attachment system <NUM> may interlock with the seatback frame <NUM> when a specific amount of force is applied. For example, the force may cause one or more components of the trim caps <NUM> to flex into place to cause the attachment system <NUM> to interlock with the seatback frame <NUM>. In this regard, the attachment system <NUM> does not require an additional interlocking assembly to secure the attachment system <NUM> with seatback frame <NUM>.

In a step <NUM>, a seatback dress cover may be fastened to the seatback frame via the modular seatback cover attachment system. For example, as shown in <FIG>, the one or more fasteners <NUM> may include one or more hook-and-loop fasteners <NUM>. For instance, the one or more panels <NUM> may be configured to couple to the one or more hook-and-loop fasteners via one or more rivet holes <NUM>. In this regard, a first side (e.g., hook side or loop side) of the one or more hook-and-loop fasteners may be coupled to a front surface of the one or more panel tabs <NUM> via the one or more rivet holes <NUM> and corresponding second side (e.g., loop side or hook side) of the one or more hook-and-loop fasteners may be coupled to a back surface of the dress cover <NUM>, such that by coupling the first side to the second side, the dress cover <NUM> may be fastened to the seatback frame <NUM> via the modular seatback cover attachment system <NUM>.

It is noted the method or process <NUM> is not limited to the steps and/or sub-steps provided. The method or process <NUM> may include more or fewer steps and/or sub-steps. In addition, the method or process <NUM> may perform the steps and/or sub-steps simultaneously. Further, the method or process <NUM> may perform the steps and/or sub-steps sequentially, including in the order provided or an order other than provided. Therefore, the above description should not be interpreted as a limitation on the scope of the disclosure but merely an illustration.

Although embodiments of the disclosure illustrate coupling or uncoupling various components of the attachment system <NUM> from above, it is noted various components of the attachment system <NUM> may be coupled or uncoupled from a front or rear direction with enough applied force. Therefore, the above description should not be interpreted as a limitation on the scope of the disclosure but merely an illustration.

It is noted the modular seatback cover attachment system <NUM> may be configured to work with any aircraft seat <NUM> and/or any set of components in the aircraft seat <NUM>. For example, the modular seatback cover attachment system <NUM> may be configured to take into account any changes in shape of the components of the aircraft seat <NUM> (e.g., within an x-y plane forming a seating surface for an occupant), where the changes in shape may be caused by or otherwise dependent on the location of the aircraft seat <NUM> within the aircraft cabin.

Although embodiments of the disclosure illustrate the modular seatback cover attachment system <NUM> being integrated with an aircraft seat <NUM> including a bezel, it is noted, however, that the attachment system <NUM> may be configured to work with an aircraft seat <NUM> without a bezel <NUM>. For example, a seatback close out device (e.g., foam shroud) may be used to cover the back of the seatback frame.

Although embodiments of the disclosure illustrate the modular seatback cover attachment system <NUM> being integrated with the seatback frame of the aircraft seat, it is noted, however, that the attachment system <NUM> may be configured to couple to a portion of the seatback bezel <NUM> or the seatback dress cover <NUM>.

Although embodiments of the disclosure illustrate the modular seatback cover attachment system <NUM> being integrated within the aircraft seat <NUM>, it is noted, however, that the modular seatback cover attachment system <NUM> and/or components of the modular seatback cover attachment system <NUM> are not limited to the aviation environment and/or the aircraft components within the aviation environment. For example, the modular seatback cover attachment system <NUM> and/or components of the modular seatback cover attachment system <NUM> may be configured for any type of vehicle known in the art. For instance, the vehicle may be any air, space, land, or water-based personal equipment or vehicle; any air, space, land, or water-based commercial equipment or vehicle; any air, space, land, or water-based military equipment or vehicle known in the art. By way of another example, the modular seatback cover attachment system <NUM> and/or components of the modular seatback cover attachment system <NUM> may be configured for commercial or industrial use in either a home or a business. Therefore, the above description should not be interpreted as a limitation on the present disclosure but merely an illustration.
