The present invention relates generally to a system and method for providing a one piece seat back panel, and, in particular embodiments, to a system and method for providing a back cover for a seat system, with the back cover being a one piece seat back panel having one or more releasable attachment mechanisms that affix the seat back panel to a seat frame without fastener openings in the seat back panel, allowing for removal of the seat back panel without tools.
Generally, advanced seating systems in vehicles such as aircraft provide multiple mechanisms for manipulating the seat. For example, advanced seating systems may include amenities such as heating or cooling systems in the seat, lumbar support, rotation systems, slide or extensions system, leg rests, entertainment options, power and data outlets, or the like, and may include power or control systems for any, or all, of the amenities. These mechanisms are frequently disposed within the seat, and due to the complexity, may need to be accessed for maintenance, repair, upgrades, and the like.
Frequently, a cover over a portion of the seat is used to permit access to internal systems. Many complex seating structures use multiple panels to cover the seat back. This requires manufacturing, tooling, and finishing of multiple parts, while increasing the number of seams between panels that need to be aligned for a neat aesthetic look. Additionally, multiple panels tend to require multiple fasteners, and in many cases, the fasteners must extend through the seat panels, requiring additional treatment for covering the fasteners.

For a more complete understanding of the present invention, and the advantages thereof, reference is now made to the following descriptions taken in conjunction with the accompanying drawings, in which:
Described herein are embodiments for providing a one piece seat back panel for a seat system. The one piece design allows for improved aesthetics of a seat back, while single part removal provides access to all back structures, and to internal structures and components. The one piece seat back panel may, in some embodiments, have integrated attachment positioning that creates a tight-fitting part that is receptive to design feature integration. Additionally, the attachment elements may be internal, so that the outer surface of the seat back panel is substantially contiguous without screws, attachment points, openings, or other interruptions in the seat back panel. Thus, the seat back panel may be configured for removal without tools. The seat back panel may be significantly larger than prior similar parts, as the single piece set back panel may be used in place of multiple smaller panels. Additionally, in some embodiments, the edges of the seat back panel are tooled, and may be fitted to a seat system, structure or arrangement so that coverings may be wrapped around the seat back panel with the edges of the covering inside the seat. Thus, the seat back panel may be a one piece precision tooled seat back panel that creates an aesthetically pleasing close out for the back of a seat system. Additionally, removal of this single part allows access to structure and components located in the seat back
The seat system 100 may have a seat back element 102 and seating surface element (not shown). The seat back element 102 and seating surface element may have contact surfaces where an occupant makes contact with the seat system 100 when sitting in the seat system 100. The seat back element 102 may have a seat back front element 108 that is padded, contoured or covered to provide support and comfort for an occupant, and to support an occupant's back when in the seat system 100. The back portion of the seat back element 102 may have a seat back panel 106 that covers the back of the seat back element 102. The seat back panel 106 is, in some embodiments, a single piece that is removable from the seat back element 102 without tools, but that securely attaches to the seat back element 102 to retain the seat back panel 106 securely when the seat back element 102 is reclined or the seat system 100 is rotated or moved. The seat back panel 106 may be disposed on the seat back element 102. The seat system 100 may have a lower back panel 112 that is attached to a fixed or non-reclining portion of the seat system 100, and may be spaced apart from the lower back panel 112 so that, when the seat back element 102 is reclined, the seat back panel 106 moves over the lower back panel 112 without contacting the lower back panel 112 to avoid the seat back panel 106 scraping the lower back panel 112 or other otherwise avoids interference with the lower back panel 112.
The seat system 100 may also have one or more armrest elements 104 with armrest top features 110. The arm rests are disposed adjacent to the seating surface element, and the seat back element 102 may be shaped to accommodate the armrest elements 104. For example, the seat back element 102 may have a lower portion that is narrowed to pass between armrest elements 104, and a top portion that is wider to provide greater support for an occupant. Thus, a seatback extension region may extend over the armrest top features 110. The seat back panel 106 may also have the extension region, and may have a lower portion narrower than the middle portion, which may include the extension regions.
One or more connector portions 322A-322C, supporting features 324, and mounting features 320A-320C may be disposed on the interior surface 326 within the interior cavity 330. In some embodiments, the seat back panel 106 may have one or more supporting features 324 that extend across the interior surface 326 to stiffen or support the center portion of the seat back panel 106. In some embodiments, the supporting features 324 may be ribs or the like that are molded into the seat back panel 106. Additionally, the supporting features 324 may extend across the interior surface 326 and may contact or support the sidewall portions 304 or upper wall portion 306. One or more supporting features 324 may extend in different directions to provide additional stiffness to the seat back panel 106, and may cross or touch each other, or touch one or more mounting features 320A-320C to support or stiffen the mounting features 320A-320C.
In some embodiments, the seat back panel 106 includes mounting features 320A-320C, such as bosses or other features, where connection features, such as connector portions 322A-322C, can be mounted. For example, in some embodiments, the mounting features 320A-320C may be bosses that are integrally formed in the seat back panel 106, and extend from the interior surface 326 into the interior cavity 330. In such an arrangement, each of the bosses may have flat faces that act as mounting surfaces and that face the front edge portion 308, and may be formed as part of a molding, casting or other formation process. For example, the seat back panel 106 may be injection molded from a thermoplastic such as polyvinyl chloride (PVC), high density polyethylene (HDPE), polycarbonate, nylon, or the like, and the mounting features 320A-320C may be molded into the seat back panel 106 as part of the injection molding process. In another example, the seat back panel 106 may be molded or laid up using a laminate such as carbon fiber, fiberglass, or the like, and the mounting features 320A-320C may be molded into the seat back panel material, or inserted into the seat back panel material during the laminating process. In other embodiments, the mounting features 320A-320C may be flat surfaces that are formed directly on the interior surface by, for example, molding flat surfaces into the interior surface 326, or machining, milling, or otherwise forming flat surfaces on the interior surface 326 after the interior surface 326 is formed. In other embodiments, the mounting features 320A-320C may be brackets, posts, or other features that are attached to the interior surface 326 after the interior surface 326 is formed. In some embodiments, the mounting features 320A-320C may be provided throughout the interior cavity 330 to provide support to various parts of the seat back panel 106. Additionally, the seat back panel 106 may be between about 24 inches high and about 36 inches high, and in some embodiments, may be about 30 inches high. The seat back panel 106 may also be between about 18 inches wide and about 28 inches wide, and in some embodiments, may be about 22 inches wide.
In some embodiments, the mounting features 320A-320C provide a surface for mounting the connector portions 322A-322C. In some embodiments, the connector portions 322A-322C may each be part of a connector structure such as a male portion of a grabber catch, that is face mounted to a surface of a respective mounting feature 320A-320C. A grabber catch may be, for example, an over-center cam latch mechanism that allows for straight-in insertion of the connector portion into a receiver portion (not shown, see
In some embodiments, the seat back panel 106 may have at least one upper mounting feature 320A with at least one upper connector portion 322A, at least one middle mounting feature 320B with at least one middle connector portion 322B, and at least one lower mounting feature 320C with at least one lower connector portion 322C. In some embodiments, the lower connector portions 322C are disposed between, or directly between the extension regions 310, and may be disposed at the top of the lower sidewall portions 312.
In some embodiments, at least one of the mounting features 320A-320C and associated connector portions 322A-322C have a different orientation than the other mounting features 320A-320C and associated connector portions 322A-322C. For example, the upper connector portions 322A may be aligned with a long axis that extends laterally, or from toward one sidewall portion 304 towards the opposite sidewall portion 304, while the middle connector portions 322B and lower connector portions 322C have long axes that extend substantially vertically, from nearest the upper wall portion 306 toward the lower edge portion 328.
In some embodiments, each receiver portion 402A-402C retains, when engaged, a corresponding connector portion 322A-322C within an opening in the receiver portion 402A-402C. Additionally, in some embodiments, the receiver portions 402A-402C retain the connector portions 322A-322C with a force of between about 1 pound and about 5 pounds, and in some embodiments, retain the connector portions 322A-322C with a force of about 3 pounds.
The use of a grabber mechanism may also permit the use of a push-to-release removal technique, where the portion of the seat back panel 106 adjacent to the respective connector portions 322A-322C is pushed, and the grabber mechanism releases so that the connector portion 322A-322C is removeable from the receiver portion 402A-402C. Similarly, the seat back panel 106 may be mounted to the seat back element 102 by aligning the connector portions 322A-322C with respective receive portions 402A-402C, and pushing at least a part of the connector portion into the corresponding receiver portion until the catch mechanism catches and retains the connector portion 322A-322C in the receiver portion 402A-402C.
