DETAILED DESCRIPTION OF THE DRAWINGS

[0036] One or more specific embodiments will be described below. In an effort to provide a concise description of these embodiments, not all features of an actual implementation are described in the specification. It should be appreciated that in the development of any such actual implementation, as in any engineering or design project, numerous implementation-specific decisions must be made to achieve the developers' specific goals, such as compliance with system-related and business-related constraints, which may vary from one implementation to another. Moreover, it should be appreciated that such a development effort might be complex and time consuming, but would nevertheless be a routine undertaking of design, fabrication, and manufacture for those of ordinary skill having the benefit of this disclosure.

[0037] Referring to the Figures, an interchangeable decorative feature for a task chair 100 is disclosed. The interchangeable decorative feature 150 provides a means for a user to customize the aesthetic functionality of a task chair, i.e., such matter serves an aesthetic function or ornamentation function. In the illustrated construction, the interchangeable feature 150 is disposed on housing 130 and in particular, is an interchangeable panel 160. According to one or more examples, the interchangeable decorative feature 150 can additionally comprise of or may alternatively include an interchangeable adhesive-backed vinyl skin 190 disposed on a rear surface of a back support 120 of a task chair 100. While specific examples are described and illustrated, the interchangeable decorative feature 150 may be disposed on any suitable seating surface for the purposes provided.

[0038] FIG. 1 is a rear perspective view of an example chair 100 having a seating surface 105, a back support 120, and an interchangeable decorative feature 150. The decorative feature 150 may be interchanged such as to modify, customize, personalize, or otherwise alter the aesthetic characteristics of a seating device. In one example, the interchangeable decorative feature 150 may be implemented as a skin, so as to form an outer surface of a chair 100. According to another example, the interchangeable decorative feature 150 may be a separate apparatus installed on a surface of a task chair 100 in the form of a panel. The interchangeable decorative feature 150 additionally accommodates curves and bends as well as joints, seams, or grooves. In the construction shown, the interchangeable decorative feature 150 is an interchangeable panel 160 made of a plastic resin (e.g., a recycled plastic) that may be molded, milled, cut, or otherwise formed into the desired shape for a particular application. Thus, the interchangeable decorative feature 150 may, in some applications, vary in thickness and pliability. While the interchangeable feature 150 is shown as a panel 160 in FIG. 1, the interchangeable decorative feature 150 may alternatively comprise an interchangeable adhesive skin 190 disposed on a surface 170, 180, or portion thereof, of the chair 100. In such an example, the skin (e.g., exterior, face, outside, shell, panel, cover, covering, casing, facing) 190 may be custom cut and shaped to fit a particular surface and/or shape of a task chair, particularly, a rear surface of a back support.

[0039] The example decorative feature 150 can be provided on a surface of most any type of seating, such as but not limited to, a task chair, an office chair, a gaming chair, airplane seating, vehicle seating, industrial equipment seating, stadium seating, theater seating, residential seating, bus seating, train seating, etc. In one construction, the decorative feature 150 may be provided, for example, on a surface of an airplane seat or a bus seat, and particularly, on a surface of a seat-back tray table as a form of advertising. The interchangeable feature 150 can be customized, personalized, modified, or altered using any suitable fabrication or manufacturing method to achieve a desired aesthetic. As mentioned above, the interchangeable feature 150 can be implemented as a panel 160, the panel being a separate surface (e.g., exterior, face, outside, shell, skin, cover, covering, facing, paneling) coupled to a surface of a chair 100. The interchangeable panel 160 may be formed of a plastic resin; however, the panel 160 may additionally or alternatively be fabricated using any suitable material for the purpose provided, such as for example, sheet metal blanks, wood laminate, cork board, or adhesive vinyl sheeting. For each of the interchangeable decorative features described herein, component variables including the thickness of the material, the type of the material used, the surface finish and texture of the material, the shape of the material, and the placement of the feature on the task chair, either alone or in any combination, provide an aesthetic functionality of the task chair 100.

[0040] Turning to FIG. 2, an example interchangeable decorative feature 150 is shown from a rear perspective and is depicted isolated from the example seating device 100 illustrated in FIG. 1. In the example construction, feature 150 comprises an upper and lower interchangeable panel 160 for a task chair 100. Each of the upper and lower interchangeable panels 160 includes an aperture 165 provided in a region to permit a support arm 110 to pass through. In one example construction, the support arm 110 is coupled to the back support 120, and more specifically to the support structure 140 of the task chair 100. The support arm 110 is secured to the support structure 140 using one or more set screws 115, thereby providing a first coupling mechanism fixing the panel 160 to the task chair 100. Best shown in FIG. 3, the set screws 115 are disposed in a region adjacent to the interchangeable feature 150 on an underside of each the support arms 110 of the task chair 100. The set screws 115 can be provided proximate a distal end of the support arms 110 in a region where the support arms 110 couple to the rear surface of the back supports 120. For the example chair 100 shown in the Figures, two set screws 115 couple the central support arm 110 to the upper back support 120, the set screws being disposed adjacent to one another in a region beneath the support arm 110 and configured to pass through an aperture 165 of the upper panel 160. Two additional set screws 115 couple the pair of lower support arms 110 to the lower back support 120, a set screw being disposed on the underside of each of the lower support arms. In the example embodiment, a pair of projections 135 extend from the housing 130 of the lower back support 120, each projection configured to pass through an aperture 165 of the lower panel 160, insert into the corresponding lower support arm 110, and receive the set screw 115 from the underside of the support arm.

[0041] Referring again to FIG. 2, the interchangeable decorative feature 150 described herein includes a primary surface 170, 180 and an opposing secondary surface 175, 185 (not shown). In the illustrated example, upper and lower panels 160 have a selected shape and dimensions. Particularly, primary surfaces 170, 180 of the interchangeable panels 160 are contoured, the top edges 172, 182 and the bottom edges 173, 183 are rounded, and the sides 171, 181 of the interchangeable panel 160 are curved to mimic the profile of the back support 120. Upper panel 160 is substantially trapezoidal in shape while the lower panel 160 is shown as being rectangular. It should be appreciated, though, that other geometric shapes are possible and the aforementioned shapes are not intended to be limiting. A cross section of the example interchangeable panel 160 includes a convex curve. In the figures, respective top, bottom, and side edges are beveled or chamfered forming a beveled surface 166 along the perimeter of the example panel 160. Best shown in FIGS. 5 and 7, the beveled surface 166 is biased towards secondary surfaces 175, 185. In other words, the beveled surface may not be viewable when assembled on task chair 100. The edges of the interchangeable panel 160 may, in some constructions, taper towards the primary surface 170, 180. In some applications, the decorative feature 150 (panel 160) may be repeatedly swapped out and/or interchanged (i.e., removed and reinstalled). Thus, the curved construction of the panel 160 may provide improved structural resilience in certain applications. While a cross section of the example interchangeable panel is described as having specified characteristics, a cross section may be other suitable shapes.

[0042] It should be understood that the interchangeable panel 160 (and thus decorative feature 150) may be manufactured in a wide variety of color schemes and designs, including solid, transparent, opaque, translucent, graphic, or any combination thereof. In some examples, the primary surface 170, 180 includes a surface finish feature 155 to provide aesthetic (ornate) functionality, tactile functionality, and in some implementations utilitarian functionality. The surface finish feature 155 can include visual indicia, such as for example, custom designs, shapes, patterns, pictures, portraits, graphical images, lettering, logos, advertising, or any combination thereof. The surface finish 155 may depend on the thickness of the material used, the type of the material used, the physical texture (or textural limitations) of the material, and the shape of the material. These factors are not intended to be limiting, it should be appreciated from this disclosure that a wide variety of factors may affect the surface finish and that these in addition to, for example, the placement of the decorative feature 150 on the task chair all combine to provide the aesthetic functionality.

[0043] The example interchangeable panel 160 may be fabricated using techniques including, but not limited to, for example injection molding, milling, machining, stamping, casting, or laminating. As such, the surface finish feature 155 can be homogenous or continuous in nature, such as for example, a suede finish, a matte finish, or a gloss finish. In the example construction shown in FIG. 2, the surface finish 155 on the primary surface 170, 180 of the interchangeable panel 160 is substantially smooth. In other examples, such as in FIGS. 3, 4, and 6, the primary surface 170, 180 can additionally or alternatively include a non-smooth surface finish feature 155, such as texturization, laser etching, surface roughening, or surface gradation/variation. In other words, surface finish feature 155 can be physically tangible. In one such example construction, the primary surface 170, 180 may be fabricated or manufactured using any suitable method to produce a surface texture resembling or mimicking an artificial or natural pattern such as for example, a carbon fiber weave or a wood grain pattern. In another example, the primary surface 170, 180 may have a non-smooth surface finish including one or more of a plurality of bumps, notches, ridges, projections, dimples, depressions, or any of a wide variety of conventional texturing shapes and configurations. The non-smooth surface finish may have a repeating pattern, including for example geometric or non-geometric shapes, or may be random in nature. While a few examples of non-smooth surface finish features 155 are described, it should be appreciated that there are many possible permutations of non-smooth surface finishes that may be provided on the interchangeable panel. Manufacturing the panel 160 to include any one of the aforementioned features allows a user to use the facing 170, 180 of interchangeable panel 160, or the panel itself, to customize, modify, personalize, or otherwise alter the design, theme, attributes, ornate characteristics, or aesthetic of the example task chair 100.

[0044] A secondary or inner surface 175, 185 of the interchangeable panels 160 is substantially smooth and may be contoured similar to the primary surface 170, 180. In one example, the inner surface 175, 185 of the interchangeable panels 160 includes one or more apertures or members to receive a snap fitting feature 200, the snap fitting feature coupling the panel to a rear surface of the back support 120 by way of an interlocking mechanism. In another example, the snap fitting feature 200 is integrated with the inner surface 175, 185 of the interchangeable panels 160. According to one or more example implementations, the interchangeable feature 150 may additionally or alternatively comprise a vinyl skin 190 coupled to a surface of the task chair 100 by way of an adhesive. While certain examples are described and shown, the interchangeable decorative feature 150 (including the interchangeable panel 160 or interchangeable vinyl skin 190) can be coupled to, adhered to, fastened on, interlocked with, imbedded in, and/or otherwise disposed on a (rear) surface of the back support 120 using any suitable manner or method including but not limited to, for example, the use of screws, tacks, clips, snaps, snap-fits, buttons, adhesive, Velcro, and the like.

[0045] FIGS. 4-7 depict exploded views of example upper and lower back supports 120 having interchangeable panels 160 coupled to the back supports by way of a snap fitting feature 200. In one application, the example snap fitting feature 200 comprises an annular snap-fit joint having a male apparatus 205 and female receiving apparatus 210, 211. The male apparatus 205 of the snap fitting feature 200 is symmetrical about a central plane running perpendicular to an axis of the apparatus. The apparatus 205 comprises two insertion ends and/or regions 206 opposite one another separated by an inner region 207. In one construction, the male apparatus 205 of the snap fitting feature 200 is substantially cylindrical having a first diameter in the insertion regions 206 and a second diameter in the inner region 207. Best shown in FIGS. 9A and 9B, the insertion ends 206 include one or more (i.e., a sequence of) annular interlocking rings (grooves or notches) 208a provided to fixedly retain the insertion ends 206 within the female apparatus 210, 211. Interlocking rings 208a are disposed spaced apart in one or more regions along an axis of the insertion ends 206. Corresponding interlocking rings 208b are disposed within the female apparatus 210, 211 to receive the interlocking rings 208a provided on the insertion ends 206 of the male apparatus 205. In the example shown, interlocking rings 208a on the insertion end 206 of the male apparatus 205 have a greater diameter than the corresponding interlocking rings 208b of the female apparatus. While sequential annular rings 208a are shown as being identical in diameter, it should be appreciated of course that interlocking rings 208a disposed closer to the inner region 207 may increase in diameter. In an operational setting, interlocking rings 208a and 208b (and thus male and female apparatuses 205 and 210, 211) may temporarily deform while snapping in and out. After interlocking, the components of the snap fitting feature 200 return to their original shape without permanent deformation.

[0046] Referring to the Figures, the female apparatus 210, 211 is provided in one or more regions on both a rear surface of the back supports 120 and the secondary surfaces 175, 185 of the interchangeable panels 160. In the example construction shown, the apparatus may be disposed integrally (210) on a surface or separately (211) as part of a post processing step. FIGS. 4 and 6 illustrate integral implementations of the female apparatus 210 which may be molded into a housing 130 of the back support 120. In the example construction, the apparatus 210 is a projection having an aperture to receive the male apparatus 205, the projection being substantially cylindrical and ring shaped. An inner portion of the apparatus 210 includes interlocking rings (grooves or notches) 208b in one or more regions to fixedly retain the male apparatus 205, thereby coupling the interchangeable panel 160 to the task chair 100.

[0047] FIGS. 5 and 7 depict non-integral implementations of the female apparatus 211. In the illustrated construction, the apparatus 211 is substantially cylindrical comprising a ring shape having an outer or exterior portion and an interior portion, the interior portion shaped to receive and fixedly retain the insertion end 206 of the male apparatus 205. In the example construction shown in the Figures, the female apparatus 211 includes rings (grooves or notches) 208b provided to secure the male apparatus 205, the rings being disposed spaced apart within the interior portion of the apparatus 211 along an axis of the female apparatus. It should be understood of course that the spacing between annular rings 208a is congruent to the spacing between interlocking rings 208b. The exterior portion of the female apparatus 211 can be contoured (e.g., having grooves, rings, notches, etc.) or threaded for securing the apparatus 211 to a surface. More specifically, the exterior portion of the apparatus 211 is configured to insert (e.g., via press-fit) into an aperture 212 disposed on an inner surface 175, 185 of the interchangeable panel 160, the aperture being an integral member of the panel. In at least one application, apertures are provided in one or more regions on the secondary surface 175, 185 of the interchangeable panel 160.

[0048] Referring to FIGS. 8 and 9, the snap fitting feature 200 is shown coupling an interchangeable panel 160 to a back support 120. In the example construction, the male apparatus 205 is pressed into the female apparatus 210, 211 such that the interlocking rings 208a provided on the male apparatus 205 snap into the rings 208b disposed within the female apparatus 210, 211 thus coupling the male and female apparatuses. In operation, a user would attribute a snapping, clicking, and/or popping noise as a successful interlocking of the interchangeable panel 160 and the back support 120.

[0049] FIG. 8 depicts a detailed view an example back support 120 for use with the chair depicted in FIG. 1. The back support 120 includes a housing 130 and support structure 140, the housing comprising the female portion 210 of the snap fitting feature 200. In the construction shown in the Figures, the female apparatus 210 is provided in one or more regions to couple the interchangeable panel 160 to the back support 120. More specifically and with reference to FIGS. 4-7, the female portion 210 of the snap fitting feature 200 is provided in four locations on the housing 130 of the upper back support 120 of the example task chair 100 and one location on the housing 130 of the lower back support 120. The female apparatus 210 is disposed in a region anchoring the four corners of the interchangeable panel 160 to the upper back support 120, best seen in FIG. 4, and in a central region coupling the interchangeable panel 160 to the lower back support 120, best seen in FIG. 6.

[0050] Disposing the snap fitting feature 200 in the regions described herein provides a complimentary anchoring point coupling the interchangeable panel 160 to the back support 120 in addition to the support arms 110. While depicted as an integral member of the housing 130 of the back support 120, the female apparatus 210 of the snap fitting feature 200 may be provided on the housing 130 as part of a post-processing step. In the sequence shown in FIGS. 9A, 9B, and 9C, the female apparatus 211 of the snap fitting feature 200 is shown disposed on an inner or secondary surface 175, 185 of the interchangeable panel 160, and particularly within an integral aperture 212. The transitional sequence illustrated in FIGS. 9A-9C demonstrate the implementation of the non-integral female apparatus 211 installed as a part of a post-processing step. In another example construction, the female apparatus 211 may be integrally formed within the interchangeable panel 160 such as described with reference to apparatus 210. In such an example construction, a thickness of the interchangeable panel may be greater in a region provided with the female apparatus 211. Accordingly, an apparatus 211 manufactured in this way provides structural resilience, for example, to resist warping or deformation of the panel 160.

[0051] The snap fitting feature 200 provides a means to couple and uncouple (e.g., install and uninstall) an interchangeable panel 160 to and from a task chair 100, thereby allowing a user to achieve a desired aesthetic. FIGS. 10 and 11 depict respective flow charts describing a method of removal and installation of an example interchangeable panel 160 for use with the task chair 100 shown in FIG. 1. Referring to FIG. 10, the example interchangeable panel 160 is coupled to the back support 120 using the snap fitting feature 200 and may additionally or alternatively be coupled or fastened to the back support by way of a support arm 110 of the task chair 100, best seen in the example construction depicted in FIG. 3. Referring to the illustrated constructions, the interchangeable panel 160 is removed in step 301 by first removing one or more set screws 115 on an underside of a support arm 110 coupling the support arm to a back support or support surface 120 of a task chair 100. Turning to step 302 and following the removal of the set screw(s) 115, the support surface 120 (including the interchangeable panel 160) is detached from the support arm and can be (entirely) removed from the task chair 100. That is, the back support 120 including the interchangeable panel 160 coupled thereto is separated (disassembled) from the support arm 110 and thus the task chair 100. Referring now to step 303, the snap fitting feature 200 may be unsnapped (i.e., uncoupled, uninstalled, removed) from the back support 120, thereby removing the panel 160 and exposing the housing 130 of the support surface 120. In step 304, the insertion end 206 of the male apparatus 205 of the snap fitting feature 200 is removed from either female apparatus 210, 211, and the male apparatus is retained for reinstallation.

[0052] Turning to FIG. 11, an interchangeable panel 160 is assembled (or reinstalled) by first installing (or replacing) the male hardware 205 of the snap fitting feature 200 into either the interchangeable panel 160 (female apparatus 211) or the housing 130 (female apparatus 210). In step 401, the male apparatus 205 is pressed into (inserted or engaged within) the receiving structure 211, 212 of the interchangeable panel 160. The interchangeable panel 160 is replaced in step 402 by pressing the panel having the snap fittings into the receiving structure 210 of the back support 120. The back support 120 including the installed panel 160 is replaced on the support arm 110, and thus the task chair 100, and secured using set screws 115. While a particular order of operations is described in reference to steps 401 and 402, the male apparatus 205 of the snap fitting feature 200 may alternatively be installed into the receiving structure 210 of the back support 120 in step 401. In such an application, the interchangeable panel 160 including the receiving structure 211, 212 may be pressed onto the back support 120 having the male apparatus 205.

[0053] In another construction, interlocking components of an example snap fitting feature according to the present disclosure can be integral with the interchangeable panel and housing of the back support. The example snap fitting feature 200a in FIG. 12 comprises a hybrid annular/cantilever snap-fit joint. Inner surfaces 175a, 185a of the interchangeable panel 160a include one or more projections, particularly, semi-annular shaped cantilever-style arms 220 extending therefrom. The example cantilever arm 220 is deflectable under strain (i.e., may be displaced under a load) and includes an interlocking feature 230 at its free end. A corresponding cavity 250 to receive the cantilever-style arm is integrally disposed on a surface of housing 130. Traditional cantilever snap-fit joints utilize square or rectangular cantilever arms and interlocking tabs. However, the disclosed semi-annular cantilever arm 220 is modified in shape having a partially formed, hollowed-out, cylindrically shaped projection (a modified half-cylinder shape). While other shapes are possible, the modified cylindrical shape aids in providing a more durable snap-fit joint compared to traditionally shaped snap-fit joints. Referring to FIGS. 13A and 13B, the example arms 220 extend a length, L, and include a shaft region 221, having radius 222, and an interlocking feature 230, having radius 232, provided at a distal end 225. A base or first end 226 of the cantilever arm is formed integrally with the interchangeable panel 160a by way of a molding or extrusion process. In some applications, the base end 226 can additionally include reinforcing ribs 227 to provide additional rigidity to the cantilever arm.

[0054] The cantilever arm 220 tapers along an axis 228 of the projection towards a second or distal end 225, which is provided with an interlocking feature. As shown, the interlocking feature 230 extends around a circumference (or portion thereof) of the modified half cylinder shape. A cross-section of the interlocking feature includes a hook-like geometric shape design (e.g., substantially resembling a J shape). In the construction shown, a beveled surface 235 of the interlocking feature 230 tapers from an outer circumference (radius 232) of the hook-like shape towards the distal end 225 of the cantilever-style arm 220. In operation, the tapered surface 235 provides the means to appropriately deflect and slide the interlocking arm 220 into the corresponding cavity 250 without permanent deformation. The hook-like geometric shape design of the interlocking feature 230 includes an undercut surface 240 configured to join with a corresponding surface within the recess on housing member 130. In some examples such as in FIG. 13, the undercut surface 240 can be tapered to aid in disassembling the snap-fit joint.

[0055] FIGS. 14A, 14B, and 14C show an example receiving cavity (e.g., recess, aperture) 250 in more detail. In the construction, the receiving cavity 250 comprises a semi-annular or modified half-cylinder shape configured to receive the cantilever arm 220. An interlocking feature 255 is provided extending around a circumference (or portion thereof) of the semi-annular cavity. As with the cantilever arm, a cross-section of the interlocking feature 255 includes a hook-like geometric shape design. Referring to FIG. 14A, a beveled surface 260 of the interlocking feature tapers towards the center of the cavity to appropriately deflect the cantilever arm 220 into the receiving cavity. In the example application, the inner radius 256 of the interlocking feature 255 is configured to mesh with the radius 222 of the cantilever arm 220. In other words, radii 222 and 256 may have substantially the same dimensions. The interlocking feature additionally includes an undercut surface 265 oriented inset the housing 130 in a region of the cavity 250 opposite the interlocking feature 255. In the example shown in the figures, the orientation of the interlocking features 230, 255 is such that when pressed together, undercut surfaces 240 and 265 hook one another (i.e., latch) coupling the panel 160a to the back support 120.

[0056] Removal and installation of panel 160a tracks similarly to the processes described in FIGS. 10 and 11; however, fewer steps are required. Integral snap-fitting 200a allows a user to assemble/disassemble panel 160a from back support 120 without the removal of additional components (i.e., components 205 and 211). Disassembly is completed by first removing set screws 115 and uncoupling the back support 120 from support arm(s) 110. In the next step, panel 160a is substantially flexible to aid in allowing a user to unsnap fitting features 200a, thereby uncoupling panel 160a from back support 120. Reassembly is easily accomplished by reversing the aforementioned steps. In operation, a user can be sure of a successful coupling of snap-fitting feature 200a via an audible sound resembling a snap or pop.

[0057] In some applications, it may not be feasible for a user to achieve a desired aesthetic using one of the interchangeable panels 160, 160a described above, for example, due to cost constraints, material constraints, or similar limiting factors. An alternative example implementation of the interchangeable feature 150 is shown illustrated in FIG. 15. The interchangeable feature 150 described herein can additionally or alternatively comprise an interchangeable vinyl skin 190 disposed on a surface of a chair 100. For example, in one application, a chair 100 can include a back support 120 and a housing 130 coupled to the back support. The decorative feature 150 may be disposed directly on the housing 130 in the form of a vinyl skin 190. In the illustrated construction, the interchangeable vinyl skin 190 can be disposed on a surface 170(a), 180(a) of the panel 160(a). Thus, depending on the application, the vinyl skin 190 can be disposed on one or more of a number of surfaces. In this way, the vinyl skin 190, either alone or in combination with a panel 160 or 160a, allows a user to customize, modify, personalize, or otherwise alter the design, theme, attributes, characteristics, or aesthetic of the example chair 100 without altering (e.g., removing and replacing) the existing panel.

[0058] The example interchangeable vinyl skin 190 is preferably manufactured using a printable adhesive vinyl paper (vinyl sheeting), the paper having one or more layers and further including a protective backing. A wide variety of vinyl sheet stock can be used for the purposes described herein; therefore, it should be appreciated that the interchangeable vinyl skin 190 may be manufactured in a wide variety of color schemes and designs, including solid, transparent, opaque, translucent, graphic, or any combination thereof. While a printable adhesive vinyl sheet is preferred, the skin 190 may be produced from any suitable sheeting alternative and may include, for example, a laminate overlay. In some applications, the vinyl skin 190 includes a surface finish feature 155. The surface finish feature 155 can include any visual indicia, for example, custom designs, shapes, patterns, pictures, portraits, graphical images, lettering, logos, advertising, etc., or any combination thereof, which may be printed thereon (e.g., using an inkjet or laser printer). As is shown, the example skin 190 is substantially flexible and may be custom sized and shaped to fit all or a portion thereof, of one or more surfaces provided on the example chair 100. The example interchangeable vinyl skin 190 may have a matte or glossy finish, and in some applications, can additionally include a laminate overlay. As mentioned above, the example interchangeable vinyl skin 190 can also be easily manufactured using relatively inexpensive materials. Thus, the skin 190 may be available for a number of different uses or applications and accessible by a larger portion of the population.

[0059] In the illustrated construction, a rear surface of the vinyl skin 190 includes a thin layer or coating of adhesive provided thereon to adhere to the surface 170, 180 of the panel 160. The adhesive layer may be a thin sheet of double stick tape, a heat activated adhesive (i.e., heat transfer), a pressure sensitive adhesive, or the like, and is preferably protected prior to installation of the skin 190 onto the panel 160 by a roll of protective peel-away paper. The adhesive layer is preferably removable, however, in some applications the vinyl skin 190 can be adhered permanently. It is preferred that, in applications where the skin 190 is removable from the task chair 100, the adhesive layer or coating not leave any adhesive or residue on the surface 170, 180 of the panel 160 when the skin is removed. In the present construction, vinyl skin 190 is shown adhered to a smooth surface; however, the skin may alternatively be configured to adhere to non-smooth surfaces.

[0060] While certain constructions of the example decorative feature 150 are described as requiring the disassembly of the example task chair 100 to interchange the skin or panel, other implementations may not require such disassembly. In such an application, the interchangeable feature 150 may be readily swapped (i.e., uncoupled and recoupled) to and from a surface. For example, a task chair 100 may not include support arms, and instead may include a seating surface 105 having a back support 120 integral thereto (i.e., the seating surface and the back support being one piece), the back support including an in-mold structure 140 provided on a surface of the back support. In this example, the interchangeable decorative feature 150 may be provided as a panel 160, 160a disposed onto or within the in-mold structure 140, thus allowing for interchangeability without disassembly of the example chair 100. In another implementation, a chair 100 can comprise a seating surface 105, a back support 120 adjacent to but separate from the seating surface, and a decorative feature 150. The decorative feature may include a panel 160, 160a, the panel being disposed on the back support. In another example, the back support may include a housing 130, the housing configured to receive the panel. The decorative feature 150 may, in some applications, further include a vinyl skin 190. In one example, the vinyl skin 190 may be provided on a panel 160, 160a coupled to a housing of a back support. In another example, the vinyl skin 190 can be provided directly on a housing of a chair. Thus, in each of the examples, the decorative feature 150 may be interchanged without the disassembly of the chair 100.

[0061] As mentioned above, the example interchangeable feature 150 may be provided on a surface of most any type of seating, such as but not limited to, a task chair, an office chair, a gaming chair, airplane seating, vehicle seating, industrial equipment seating, stadium seating, theater seating, residential seating, bus seating, train seating, etc. In one application, the feature 150 may be provided, for example, on a surface of an airplane seat or a bus seat, and particularly, on a surface of a seat-back tray table as a form of advertising. In another implementation, the decorative feature 150 may be provided as an in-mold decorated part, and in some applications, the feature 150 may supplement or compliment the aesthetic attributes or characteristics of a housing 130 or support structure 140 of a back support 120. In one such example, the decorative feature 150 may be a transparent interchangeable panel 160, 160a disposed on a back support 120. The transparent panel 160, 160a provides a viewing window to within the back support such that a user may include additional features (e.g., lighting, LEDs, display screens, electronic components or devices) to contribute to or compliment the existing aesthetic attributes of the example chair 100.

[0062] Although implementation of the decorative feature 150 is particularly well suited for an aftermarket application, it should be understood that the feature 150 may be provided with task chairs of original manufacture. The skins 190 or panels 160 described herein may be manufactured and sold separately as an aftermarket product for application to task chairs, or may be applied to chairs of original manufacture. In addition, it should be appreciated that the skins or panels according to one or more constructions may be integral to the task chair, or their components, such as the housing or support structure.
