[0027] Reference Figure 1 illustrates an example of a seat assembly 10. In some embodiments, the seat assembly 10 is a vehicle seat assembly, for example for a land vehicle such as a car, truck, bus, etc., or for a non-land vehicle such as an aircraft or a ship. For example, the seat assembly 10 for a land vehicle can be shaped and sized to serve as a front-row driver or occupant seat, a second-row seat, a third-row seat, or other rear-row seat, and can include a bucket seat, a bench seat, or other seat styles as shown. Additionally, the seat assembly 10 can be a non-retractable seat or a retractable seat, and the retractable seat can be folded and stowed in a cavity in the vehicle floor. Further, the seat assembly 10 can be constructed for non-vehicle applications, such as furniture.

[0028] In Figure 1 the illustrated configuration, the seat assembly 10 includes a seat bottom 20 and a seat back 22. It is contemplated that in some configurations the seat back 22 can be omitted, for example when the seat assembly 10 is constructed as a motorcycle seat or a stool.

[0029] The seat bottom 20 is configured to receive a seated occupant and support the pelvis and thighs of the seat occupant. The seat bottom 20 includes a seat bottom frame 30, padding 32, and a cover 34.

[0030] The seat bottom frame 30 is a structure that supports the padding 32. The seat bottom frame 30 includes one or more structural members and can be made of any suitable material, such as a metal alloy, a polymeric material, a fiber-reinforced polymeric material, or a combination thereof. In some configurations, the seat bottom frame 30 includes a panel on which the padding 32 is disposed, a seat pan, a suspension pad, or a suspension wire.

[0031] The padding 32 is disposed on the seat bottom frame 30. The padding 32 is made of a flexible material that supports the seat occupant and distributes the load forces from the seat occupant to the seat bottom frame 30. The padding 32 and related manufacturing methods will be discussed in more detail below.

[0032] The trim cover 34 covers at least a portion of the cushion 32. Additionally, the trim cover 34 provides one or more visible outer surfaces of the seat back 22. When seated on the seat assembly 10, the seat occupant can sit on the trim cover 34. The trim cover 34 is made of any suitable one or more materials, such as fabric, leather, faux leather, vinyl, or combinations thereof. The trim cover 34 can include a plurality of trim panels assembled in any suitable manner, such as by fusing or stitching. The trim cover 34 is attached to the seat bottom frame 30, the cushion 32, or both. For example, the trim cover 34 can include trim attachment features that attach to the seat bottom frame 30, the cushion 32, or both to inhibit removal of the trim cover 34 and to help the trim cover 34 conform to the profile of the seat bottom frame 30, the cushion 32, or both. The trim cover 34 can also be attached to an attachment pad, which will be discussed in more detail below.

[0033] The seat back 22 is configured to support the back of a seated occupant. The seat back 22 is disposed adjacent to the seat bottom 20. For example, the seat back 22 can be disposed above the seat bottom 20 and near the rear side of the seat bottom 20. The seat back 22 extends in a generally upward direction away from the seat bottom 20. In some configurations, the seat back 22 is mounted to the seat bottom 20 and can pivot relative to the seat bottom 20. In other configurations, the seat back 22 is not mounted to the seat bottom 20. For example, a vehicle seat back can be mounted to the vehicle body structure, such as in some second row seat assemblies. The seat back 22 includes a seat back frame 40, a cushion 42, a trim cover 44, and an optional headrest 46.

[0034] The seat back frame 40 is a structure that supports the cushion 42. The seat back frame 40 includes one or more structural members and can be made of any suitable material, such as a metal alloy, a polymer material, a fiber-reinforced polymer material, or combinations thereof. In some configurations, the seat back frame 40 includes a panel, a bottom plate, a suspension pad, or suspension wires on which the cushion 42 is disposed. It is also contemplated that in some configurations, the seat back frame 40 can be integrally formed with the seat bottom frame 30.

[0035] The cushion 42 is disposed on the seat back frame 40. The cushion 42 is made of a flexible material that supports the seat occupant and distributes the load forces from the seat occupant to the seat back frame 40. It is contemplated that the cushion 42 can be integrally formed with the cushion 32 of the seat bottom 20 or can be separate from the cushion 32 of the seat bottom 20. The cushion 42 and related manufacturing methods will be discussed in more detail below.

[0036] The trim cover 44 covers at least a portion of the cushion 42. Additionally, the trim cover 44 provides one or more visible outer surfaces of the seat back 22. When seated on the seat assembly 10, the seat occupant may rest on the trim cover 44. The trim cover 44 is made of any suitable single material or combination of materials (such as fabric, leather, faux leather, vinyl, or combinations thereof). The trim cover 44 may include one trim panel or more trim panels that are assembled in any suitable manner (such as by fusing or stitching). The trim cover 44 is attached to the seat back frame 40, the cushion 42, or both. For example, the trim cover 44 may include decorative attachment features that attach to the seat back frame 40, the cushion 42, or both to inhibit removal of the trim cover 44 and to help the trim cover 44 conform to the profile of the seat back frame 40, the cushion 42, or both. The trim cover 44 may also be attached to an attachment pad, which will be discussed in more detail below.

[0037] The headrest 46 (if provided) is configured to support the head of the seat occupant. The headrest 46 is disposed at the top of the seat back 22, or at an end of the seat back 22 opposite the seat bottom 20. The headrest 46 may be movable relative to the seat back 22 in one or more directions, or may be integrally formed with the seat back 22.

[0038] Reference Figure 2 , the material supplier 70 holds a material stock to be extruded, such as beads, flakes, granules, pellets, or powders of solids made of the material. In some configurations, the material supplier 70 is configured as a container or hopper. The material supplier 70 supplies the material stock to the extruder 72.

[0039] The extruder 72 melts the material stock and extrudes the material stock into a set of filaments 52. The extruder 72 may have any suitable configuration. In some configurations, the extruder 72 includes a barrel that receives a rotatable screw and a heating element. Rotation of the screw forces the material through the barrel and helps heat the material due to the friction generated when the screw rotates. The material exits the barrel under pressure and in a molten state and is conveyed under pressure to a die 80 of the extruder 72.

[0040] The die 80 (which may also be referred to as a die plate or extrusion die) has a plurality of through-holes or openings for forming filaments through which the molten material passes. A single filament 52 is extruded from each through-hole. The filaments 52 fall downward from the die 80 into the funnel 74 under the action of gravity.

[0041] The funnel 74 combines or groups the filaments 52 into a more compact arrangement where the filaments are bent, curled, or looped, and the filaments 52 contact and bond to at least one other filament 52. The funnel 74 has an inlet opening or funnel inlet and an outlet opening or funnel outlet that is smaller than the funnel inlet. The individually separated filaments 52 enter the funnel inlet. As the filaments 52 accumulate, the filaments 52 bend, curl, or loop and move into contact. The filaments 52 travel through the funnel 74 toward the funnel outlet. As the filaments move toward the funnel outlet, some of the filaments may slide along the funnel 74 or along an intervening sheet disposed on the funnel 74. A bond forms between the filaments 52 at the contact points, while at other locations where one filament 52 does not contact or bond to another filament 52, there are openings or voids between the filaments 52. The wound and bonded filaments 52 pass through the funnel outlet of the funnel 74 and into the cooling tank 76. For ease of reference, the bonded filaments 52 are referred to as the mesh member or wire mesh structure 90.

[0042] The cooling tank 76 contains a liquid, such as water or a mixture of water and another fluid. The liquid in the cooling tank 76 helps support the wound and bonded filaments 52 to limit further compaction or consolidation of the filaments 52 into an arrangement with fewer openings or fewer pores and to maintain the desired porosity and density of the wire mesh structure 90. Thus, the liquid provides some buoyancy or drag forces that can cause additional bending, curling, or looping of the filaments 52 adjacent to the liquid surface or within the funnel 74 to further construct the wire mesh structure 90. When the filaments 52 are in the liquid, the liquid also cools the filaments 52. For example, the liquid cools the filaments 52 from the outside to solidify the filaments 52 and prevent the filaments 52 from bonding at additional locations. At this time, the filaments 52 are relatively rigid and no longer in a plastic state, so they generally maintain their shape and are not plastifiable or reformable without being reheated.

[0043] The material handling subsystem 78 conveys the wire mesh structure 90 through the cooling tank 76. The material handling subsystem 78 includes various rollers and conveyors that assist in moving the wire mesh structure 90 through the liquid and out of the liquid. In some configurations, a traction conveyor 92 is disposed in the cooling tank 76 to help pull the wire mesh structure 90 from the funnel 74 and counteract the buoyancy of the filaments 52.

[0044] One or more other rollers (such as roller 94) keep the wire mesh structure 90 immersed in the liquid and guide the wire mesh structure 90 through the cooling tank 76. For example, roller 94 can guide the wire mesh structure 90 towards the conveyor belt 96 and the shaker table 98 disposed outside the cooling tank 76. The shaker table 98 vibrates the wire mesh structure 90 while the wire mesh structure 90 is on the conveyor 96 to remove the liquid. Alternatively or additionally, the wire mesh structure 90 can be squeezed to remove the liquid, air can be blown onto the wire mesh structure 90 to remove the liquid, or both. It is also contemplated that the wire mesh structure 90 can also be allowed to dry, or dried in ambient air.

[0045] The above-described manufacturing system 60 is a continuous flow process in which the wire mesh structure 90 is formed as a continuous structure when the extrusion of the filaments is not interrupted. After leaving the cooling tank 76, further processing of the wire mesh structure 90 is provided to cut the wire mesh structure 90 into individual pieces or blanks for individual pads. This processing is performed by the cutting subsystem of the manufacturing system 60. The cutting system can be of any suitable type. For example, the cutting system can use a blade, knife, hot knife, saw, fluid jet, etc. to cut the filaments 52 of the wire mesh structure 90 into blanks. The cutting system can be used to shape or contour the blanks. It is also contemplated that the blanks can be further shaped or contoured with other manufacturing processes, such as molding the entire blank or a portion thereof.

[0046] Reference Figure 3A and Figure 3B , an example of a pad 50 is shown. For ease of reference, the pad is generally denoted by the reference numeral 50. It should be understood that the structure and description of the pad 50 apply to the pad 32 of the seat bottom 20, the pad 42 of the seat back 22, or both.

[0047] The pad 50 is a non-foam component or includes at least one non-foam component. The non-foam component is mainly referred to as a mesh member, but can also be referred to as a wire member, a looped member, a tangled member, a wire mesh structure, a mesh structure, a wire net, a looped net, a tangled net, or a mesh pad. The pad 50 is described below without including a foam material. In this case, the pad 50 is made of filaments 52 of a polymeric material, and the filaments 52 are randomly looped, bent, curled, or tangled and bonded together. The filaments 52 are directly bonded to another filament 52 without providing a resin or other intermediate material for indirect bonding.

[0048] The filament 52 can also be referred to as a strand or a thread and is made of any suitable single material or more than one material. In some configurations, the filament 52 is made of a polymeric material or a thermoplastic material, such as a thermoplastic resin based on polyamide, polyester, polyimide, polyolefin (e.g., based on polypropylene, polyethylene, etc.), polystyrene, or a combination thereof. As an example, a polyethylene-based filament can be made of linear low-density polyethylene (LLPDE). Different from foam materials, the filament material can be recyclable or easier to recycle than foam materials. It is also conceivable that the filament 52 can include reinforcing fibers, and the reinforcing fibers may not be made of a thermoplastic material.

[0049] In some configurations, the filament 52 can be a monofilament made of a single material. In some configurations, the filament 52 is made of multiple materials. For example, the filament 52 made of multiple materials can include a core made of a first thermoplastic material and an outer sheath that surrounds the core and is made of a second thermoplastic material different from the first thermoplastic material. It is conceivable that the liner 50 can include a combination of monofilaments and filaments made of multiple materials and is not a monofilament.

[0050] The randomly looped, bent, curled, or wound filaments 52 are joined together where one filament 52 contacts another filament 52, thereby producing a lightweight, breathable liner (e.g., liner 32 and / or liner 42) or a mesh structure (with openings or voids between the filaments 52). Figure 2 An example of a manufacturing system 60 for manufacturing a liner or a wire mesh structure is shown. In this example, the manufacturing system 60 includes a material feeder 70, an extruder 72, and a funnel 74. The manufacturing system 60 also includes a cooling tank 76 and a material handling subsystem 78.

[0051] Reference Figure 3A , an exploded view of a part of the seat assembly 10 is shown, which includes an example of the liner 50 and an example of the trim cover 100. The trim cover 100 can be made of fabric, textile, or fabric material. The trim cover 100 can also be referred to as a sheet or a cloth cover. The liner 50 includes a wire mesh structure 90. In Figure 3A For clarity, the liner 50 is shown without depicting the individual filaments 52 of the wire mesh structure 90. In some configurations, the liner 50 has a contoured exterior side 110. The contoured exterior side 110 can have a partially or completely non-planar profile and can include one or more curved surfaces or curved regions. In some configurations, the contoured exterior side 110 is concave or partially concave. The contoured exterior side 110 faces the trim cover 100. In addition, the contoured exterior side 110 can face the seat occupant. The contoured exterior side 110 can contact a part of the trim cover 100 in one or more regions.

[0052] For ease of reference, the trim cover 100 is generally designated by the reference numeral 100. It should be understood that the trim cover 100 can be the trim cover 34 of the seat bottom 20 or the trim cover 44 of the seat back 22 as described above. Figure 3A A portion of the trim cover 100 is shown in the figure to make other features in the figure more visible. The trim cover 100 is disposed on a cushion 50 including a mesh structure 90 and, when fixed to the cushion 50, can generally follow the curvature or contour of the cushion 50. The trim cover 100 and the cushion can together form a manufactured product, such as a vehicle seat bottom 20 or a vehicle seat back 22.

[0053] Reference Figure 4 is made to a separately shown cushion 50 including a mesh structure 90 and a trim cover 100 to show an attachment system 112 for attaching the trim cover 100 to the mesh structure 90. The attachment system 112 can more specifically be one or more hook-and-loop fastening systems (e.g., ). Each hook-and-loop fastening system includes a loop portion 114 and a hook portion 116. One of the loop portion 114 and the hook portion 116 is attached to the mesh structure 90, and the other of the loop portion 114 and the hook portion 116 is attached to the trim cover 100. The loop portion 114 and the hook portion 116 cooperate to attach the trim cover 100 to the mesh structure 90 to together form a product (e.g., a seat bottom 20 or a seat back 22).

[0054] It should be noted that the loop portion 114 is shown attached to the trim cover 100, and the hook portion 116 is shown attached to the mesh structure 90. This configuration can be preferred because the loop portion 114 (i) can have a softer feel for a user who is engaging the product formed by the mesh structure 90 and the trim cover 100 (e.g., a seat bottom 20 or a seat back 22), and (ii) does not increase the rigidity of the trim cover 100. However, if desired, an alternative configuration can be utilized (e.g., the hook portion 116 can be attached to the trim cover 100, and the loop portion 114 can be attached to the mesh structure 90).

[0055] The loop portion 114 can be attached to the decorative cover 100 via a number of systems or methods and the hook portion 116 can be attached to the wire mesh structure 90, or vice versa. In the following description of a number of attachment systems or methods, reference is made to the loop portion 114 attached to the decorative cover 100 and the hook portion 116 attached to the wire mesh structure 90. However, it should be understood that for alternative configurations in which the loop portion 114 can be attached to the wire mesh structure 90 and in which the hook portion 116 is attached to the decorative cover 100, the reference to the loop portion 114 can be replaced by a reference to the hook portion 116 and the reference to the hook portion 116 can be replaced by a reference to the loop portion 114.

[0056] In Figure 5 In a first example of the attachment system or method shown, the loop portion 114 is attached to the decorative cover 100 via a first adhesive 118 and the hook portion 116 is attached to the wire mesh structure 90 via a second adhesive 120. The first adhesive 118 and the second adhesive 120 can be spray adhesives, heat-activated adhesives, pressure-activated adhesives, epoxy resins, resins, light-curing adhesives (e.g., ultraviolet light-curing adhesives) or any other type of adhesive known in the art. For example, the adhesive can be composed of the same material as the wire mesh structure 90 or other compatible materials. Alternatively, the loop portion 114 can be attached to the decorative cover 100 and the hook portion 116 can be attached to the wire mesh structure 90 via lamination or sonic welding. The first adhesive 118 and the second adhesive 120 can be disposed along the surfaces of the loop portion 114 and the hook portion 116 that respectively engage the decorative cover 100 and the wire mesh structure 90, the surfaces of the loop portion 114 and the hook portion 116 being opposite the surfaces of the loop portion 114 and the hook portion 116 that are configured to engage each other to secure the loop portion 114 to the hook portion 116.

[0057] Removable material films can be disposed over the first adhesive 118 and the second adhesive 120 on the loop portion 114 and the hook portion 116 respectively. Such removable films can provide protection for the first adhesive 118 and the second adhesive 120 before the loop portion 114 and the hook portion 116 are respectively secured to the decorative cover 100 and the wire mesh structure 90. The removable films can be removed prior to securing the loop portion 114 and the hook portion 116 to the decorative cover 100 and the wire mesh structure 90 respectively, to expose the first adhesive 118 and the second adhesive 120 such that the first adhesive 118 and the second adhesive 120 can respectively engage the decorative cover 100 and the wire mesh structure 90 to secure the loop portion 114 and the hook portion 116 to the decorative cover 100 and the wire mesh structure 90 respectively.

[0058] In Figure 6In a second example of the attachment system or method shown, the barbed portion 116 is attached to the screen structure 90 via a combination of one or more retainers 122 and connectors 124. The combination of a single retainer 122 and connector 124 can be referred to as a retainer assembly 130. Each connector 124 extends from the back of the barbed portion 116 through the screen structure 90 and to a corresponding retainer 122. The retainer 122 engages the side 126 of the screen structure 90 that is opposite the attachment system 112 (e.g., the barbed loop fastening system). The attachment system 112 is disposed along side 128 of the screen structure 90, which side 128 is opposite the opposite side 126 of the screen structure 90. The loop portion 114 can be attached to the Figure 5 decorative cover 100 in the same manner as described above with respect to Figure 6 (e.g., the loop portion 114 can be attached to the decorative cover 100 via any adhesive, lamination, sonic welding, etc. known in the art).

[0059] Figure 7 And Figure 8 The retainer assembly 130 is shown in more detail. The retainer assembly 130 can be placed in a gasket 50 that includes the screen structure 90. In the illustrated embodiment, the barbed portion 116 can be attached to the retainer assembly 130, while the loop portion 114 can be attached to the decorative cover 110. The connector 124 can be stitched to the barbed portion 116. The connector 124 can also be stitched to the retainer 122. The width of the connector 124 can be less than the width of the barbed portion 116. The retainer 122 can include a thickness that is less than the width of the retainer 122. The connector 124 extends through a slot 132 in the gasket 50 that includes the screen structure 90. The connector 124 can be constructed of a textile material such as fabric, cloth, etc.

[0060] The back of the barbed portion 116 can be connected to a barbed portion plate (e.g., similar to plate 404 discussed below with respect to the fourth example of the attachment system or method), which plate is used to increase the rigidity of the barbed portion 116. The barbed portion 116 can be connected to such a plate via an adhesive or via threading (e.g., the barbed portion 116 can be stitched to the plate). The plate can in turn be connected to the connector 124. Once installed, the plate can engage the exterior (e.g., side 128) of the screen structure 90.

[0061] The width of retainer 122 can be greater than the width of connector 124. Retainer 122 can be pivotally attached to connector 124 and spaced apart from barb portion 116. For example, retainer 122 and barb portion 116 can be fixed to opposite ends of connector 124. Retainer 122 can pivot outside of gasket 50 that includes screen structure 90 such that the width of retainer 122 engages gasket 50 that includes screen structure 90. Retainer 122 holds barb portion 116 on gasket 50 that includes screen structure 90. Retainer 122 can be constructed of a polymeric material.

[0062] Reference Figure 7 , retainer assembly 130 is shown as being partially inserted into gasket 50 that includes screen structure 90. Retainer 122 of retainer assembly 130 is collapsed along connector 124 of retainer assembly 130. Then retainer 122 and connector 124 are inserted into slot 132 that is formed through gasket 50 that includes screen structure 90. Retainer 122 can be translated through gasket 50 that includes screen structure 90 while connector 124 remains at least partially within slot 132. Then, retainer 122 can be deployed relative to connector 124 to contact an area of gasket 50 that includes screen structure 90 adjacent slot 132 to hold connector 124 within slot 132. Figure 8 Retainer assembly 130 fully installed within gasket 50 that includes screen structure 90 is shown, where barb portion 116 and retainer 122 are disposed on and engage opposite sides (e.g., side 128 and opposite side 126, respectively) of gasket 50 that includes screen structure 90. Figure 8 Also shown is the engagement between loop portion 114 and barb portion 116 to secure decorative cover 100 to gasket 50 that includes screen structure 90.

[0063] In Figure 9In a third example of the attachment system or method shown, the barbed portion 116 is attached to the wire mesh structure 90 via one or more hooks 233. The one or more hooks 233 extend from the back of the barbed portion 116 into the wire mesh structure 90 and engage at least one wire 52 in the set of wires 52. More specifically, the hook 233 can extend from a side of the barbed portion 116 opposite the barb that is configured to engage the loop portion 114. More specifically, the hook 233 can be attached to and extend from a bracket 235. The barbed portion 116 is in turn connected to the bracket 235. The barbed portion 116 can be attached to the bracket 235 via an adhesive (e.g., any adhesive described herein or known in the art), lamination, sonic welding, etc. When the bracket 235 is mounted on the wire mesh structure 90, the surface of the bracket 235 opposite the hook 233 can be flush with the exterior of the wire mesh structure 90. The loop portion 114 can be attached to the Figure 5 decorative cover 100 in the same manner as described above with respect to Figure 9 (e.g., the loop portion 114 can be attached to the decorative cover 100 via any adhesive known in the art, lamination, sonic welding, etc.). The hook 233 and the bracket 235 can form part of a clip 200 that is configured to secure the barbed portion 116 to the wire mesh structure 90.

[0064] Reference Figures 10 to 13 shows the clip 200 in more detail. The clip 200 includes a plurality of hooks 233 and brackets 235. The clip 200 is configured to secure the barbed portion 116 to a backing, such as the backing 50 that includes the wire mesh structure 90. The clip 200 is made of any suitable one or more materials. In some configurations, the clip 200 is made of a polymeric material. The clip 200 can be made of the same material as the wire 52 or a different material than the wire 52. The polymeric material can be recyclable. The clip 200 is manufactured using any suitable process. For example, the clip 200 can be molded or fabricated using an additive manufacturing process (e.g., 3D printing). It is contemplated that the clip 200 is manufactured as an integral one-piece component that can be cut to a length suitable for installation in the wire mesh structure 90.

[0065] The clip 200 includes one or more clip segments 210. In configurations having multiple clip segments 210, a spine 212 is provided with the clip 200. In such a configuration, the spine 212 interconnects the clip segments 210. The clip segments 210 are spaced apart from each other such that a gap 214 is provided between one clip segment 210 and an adjacent clip segment 210. The clip 200 will be described primarily in the context of the clip 200 having multiple clip segments 210.

[0066] Reference Figure 10 and Figure 11, an example of the spine 212 is shown. The spine 212 is flexible and allows the clip segments 210 to be positioned relative to each other in various orientations. As Figure 10 shown, when the spine 212 is in a free state, the spine 212 can be straight or extend along a straight spine axis 220. The spine 212 includes a bottom side 230 and a top side 232. The bottom side 230 faces away from the clip segments 210. In some configurations, the bottom side 230 extends the length of the clip 200. The top side 232 is disposed opposite the bottom side 230. Thus, the top side 232 can face the clip segments 210. In some configurations, the top side 232 is segmented and extends from one clip segment 210 to an adjacent clip segment 210, or is visible between adjacent clip segments 210, 210.

[0067] In Figure 10 and Figure 11 the configurations shown, the spine 212 is positioned below the clip segments 210. It is also conceivable that the spine 212 can be positioned at a higher height than shown in these figures. For example, the spine 212 can extend from the side of the first clip segment 210 facing the adjacent second clip segment 210 to the corresponding side of the adjacent clip segment 210 facing the first clip segment 210, rather than being disposed below one or more clip segments 210. As an example, the spine 212 can be moved upward from the Figure 11 position shown such that Figure 11 the top surface 232 in becomes the bottom surface 230, and from the perspective shown, the top surface 232 can be hidden behind the clip segments 210.

[0068] Referring primarily to Figure 11 , the clip segments 210 include at least one retaining feature, such as one of the brackets 235. The brackets 235 extend upward from the spine 212. In some configurations, the brackets 235 extend from the top side 232 of the spine 212. The brackets 235 are shown extending upward from the spine 212 via two struts 237, which creates a cavity 239. In some configurations, the brackets 235 can extend directly upward from the spine 212, with the cavity 239 filled and the struts 237 eliminated.

[0069] The brackets 235 can extend away from the spine 212 in a first direction 252 along or relative to a central plane 254 of the clip segments 210. The central plane 254 can bisect the clip segments 210. The first direction 252 extends away from the spine 212, or extends in an upward direction from the Figure 11 perspective shown. The central plane 254 can extend through the spine 212. For example, the central plane 254 can bisect the spine 212. The central plane 254 can also bisect the brackets 235. The spine axis 220 can be disposed in the central plane 254 of the clip segments 210, such as when the clip 200 is in a free state.

[0070] The clip segment 210 is provided with one or more barbs 242. The barbs 242 can correspond to the hooks 233. The barbs 242 extend from the bracket 235, the spine 212, or both. In Figure 11 the example shown, two barbs 242, 242 are shown, each barb 242 extending from the bracket 235 and the spine 212. In some configurations, the barbs 242 are spaced from the spine 212 and do not extend from the spine 212. In such a configuration, the barbs 242 extend from the corresponding bracket 235 in a direction extending away from the central plane 254. Similarly, the barbs 242 extending from the spine 212 can also extend in a direction extending away from the central plane 254.

[0071] The barbs 242 are arranged in a relationship that is neither parallel nor perpendicular to the central plane 254. In addition, the barbs 242 are oriented to extend away from the bottom side 230 of the spine 212, or extend upward from the Figure 11 perspective shown. Thus, as the distance from the spine 212 increases, the barbs 242 extend in the first direction 252. In this way, as the barbs 242 extend away from the spine 212 and the central plane 254, the barbs 242 can extend further away from the bottom side 230. In the configuration shown, the first barb 242 extends away from the second barb 242. Thus, the first barb 242 and the second barb 242 can extend in opposite directions relative to each other or relative to the central plane 254.

[0072] The barbs 242 can extend away from the bottom side 230 in a linear or non-linear manner. In Figure 11 the example shown, each barb 242 is shown extending along a corresponding barb axis 270. The barb axis 270 intersects the central plane 254 at an acute angle 272, as Figure 11 shown, and when viewed from above or in a plan view, the barb axis 270 can be arranged to be substantially perpendicular to the central plane 254, as Figure 12 shown. The term "substantially perpendicular" is used herein to denote a feature or axis that is the same as or very close to perpendicular, and includes features within the range of ±3° of being perpendicular to each other. In some configurations, the barb axis 270 intersects the central plane 254 at a location that does not intersect the spine 212 (such as along the bracket 235). It is also conceivable that the barbs 242 can be curved or extend in a non-linear manner. For example, the barb 242 or a portion thereof can extend along an arc or curve that can bend upward from the perspective shown or bulge relative to the spine 212.

[0073] In some configurations, the barbs 242 include an upper side 280, a lower side 282, a first lateral side 284, and a second lateral side 286.

[0074] The upper side 280 faces away from the spine 212. In some configurations, the upper side 280 extends from the corresponding bracket 235. For example, the upper side 280 may intersect or extend from the corresponding bracket 235. When the upper side 280 extends away from the corresponding bracket 235 (from which the upper side 280 extends), the upper side 280 further extends away from the spine 212. The upper side 280 may have a planar or non-planar configuration.

[0075] The lower side 282 is disposed opposite to the upper side 280. Thus, the lower side 282 faces the spine 212. In some configurations, the lower side 282 extends from the corresponding bracket 235. In some configurations, the lower side 282 intersects or extends from the spine 212. The lower side 282 may have a planar or non-planar configuration. When the lower side 282 extends away from the corresponding bracket 235 (from which the lower side 282 extends), the lower side 282 further extends away from the spine 212. In some configurations, the lower side 282 has a length greater than that of the upper side 280.

[0076] In some configurations, the lower side 282 is disposed substantially parallel to the upper side 280. As used herein, the term "substantially parallel" means the same as or very close to parallel, and includes features or axes within ±3° of being parallel to each other. When the lower side 282 is disposed substantially parallel to the upper side 280, the lower side 282 does not intersect the upper side 280. In some configurations, the lower side 282 and the upper side 280 are disposed in a non-parallel relationship. For example, as the distance from the central plane 254 increases, the lower side 282 and the upper side 280 may become closer together. In some configurations, it is conceivable that the lower side 282 may intersect the upper side 280, such as at the distal end of the barb 242.

[0077] Reference Figures 11 to 13 Figure, the first lateral side 284 extends from the corresponding bracket 235. The first lateral side 284 extends from the upper side 280 to the lower side 282. As Figure 12 best shown, as the distance from the central plane 254 increases, the first lateral side 284 extends towards the second lateral side 286. For example, as the distance from the central plane 254 increases, the first lateral side 284 may extend towards or become closer to the corresponding barb axis 270. It is also conceivable that the first lateral side 284 may be planar or non-planar.

[0078] The second lateral side 286 extends from the corresponding bracket 235 and is disposed opposite the first lateral side 284. The second lateral side 286 extends from the upper side 280 to the lower side 282. As the distance from the central plane 254 increases, the second lateral side 286 extends toward the first lateral side 284. For example, as the distance from the central plane 254 increases, the second lateral side 286 may extend toward or become closer to the corresponding barb axis 270. Such a configuration facilitates the installation of the clip 200 into the gasket 50. It is contemplated that the second lateral side 286 may be planar or non-planar.

[0079] In some configurations, the first lateral side 284 intersects the second lateral side 286 at the distal end 292 of the barb 242. When the first lateral side 284 and the second lateral side 286 have a vertically oriented planar configuration, this may result in the barb 242 having a triangular configuration when viewed from above, as Figure 12 best shown in. It is also contemplated that the distal end 292 may be rounded or have a radius rather than meeting along a linear edge.

[0080] Inserting the clip 200 into the wire mesh structure 90 causes the barb 242 to intersect the wire 52 such that at least some of the wires 52 contact the barb 242 and the barb 242 is captured in the wire 52, thereby holding the clip 200 in the wire mesh structure 90. At least a portion of the barb 242 is received in the void or gap between a plurality of wires of a set of wires 52. The barb 242 contacts one or more of the wires of the set of wires 52.

[0081] Due to the wires 52 being looped or coiled, the wires 52 may contact the clip 200 at various positions. In some configurations, at least one of the wires of the set of wires 52 contacts the first barb 242 and the second barb 242 of the clip segment 210.

[0082] In some configurations, at least one filament of the set of filaments 52 contacts more than one clip segment 210. As an example, the clip segment 210 can be inserted into a slit defined by the wire mesh structure 90. At least one filament of the set of filaments 52 contacts a first clip segment 210 and a second clip segment 210. The filament 52 can loop or curl around the barbs 242 of the first clip segment 210 and the barbs 242 of the second clip segment 210 and contact the barbs 242 of the first clip segment 210 and the barbs 242 of the second clip segment 210; however, it should be understood that the filament 52 does not need to form a closed loop around or encircle one or both barbs 242. For example, the filament 52 can extend over the barb 242 and engage the upper side 280, can contact the other side of the barb 242, or a combination of both. For example, a filament contacting the lower side 282 of the barb 242 can help limit downward movement or tilting of the clip 200, and a filament 52 contacting the lateral side (e.g., the first lateral side 284 or the second lateral side 286) of the barb 242 can prevent or limit movement of the clip 200 along or within the slit in at least one direction.

[0083] Reference Figure 14 , a flowchart of a method 300 for securing a trim cover 100 to a pad 50 including a wire mesh structure 90 is shown. Method 300 begins at block 302, where a first portion (e.g., one of the loop portion 114 and the hook portion 116) of a hook-and-loop fastening system (e.g., attachment system 112) is attached to a wire mesh member (e.g., wire mesh structure 90). Next, method 300 moves to block 304, where a second portion (e.g., the other of the loop portion 114 and the hook portion 116) of the hook-and-loop fastening system is attached to the trim cover (e.g., trim cover 100). Method 300 then moves to block 306, where the first portion (e.g., one of the loop portion 114 and the hook portion 116) of the hook-and-loop fastening system engages the second portion (e.g., the other of the loop portion 114 and the hook portion 116) of the hook-and-loop fastening system to secure the trim cover (e.g., trim cover 100) to the wire mesh member (e.g., wire mesh structure 90), thereby forming a product (e.g., seat bottom 20 or seat back 22). It should be understood that Figure 14 the flowchart in Figure 14 is for illustrative purposes, and method 300 should not be construed as limited to

[0084] In Figure 15 and Figure 16In a fourth example of the attachment system or method shown, the barbed portion 116 is attached to the wire mesh structure 90 via a clip 400. The clip 400 includes one or more first hooks 402 that extend from the back of the barbed portion 116 into the wire mesh structure 90 and engage at least one wire 52 of the set of wires 52. More specifically, the one or more first hooks 402 may extend from a side of the barbed portion 116 opposite the barbs configured to engage the loops of the loop portion 114. The back of the barbed portion 116 may be connected to a plate 404 that serves to increase the rigidity of the barbed portion 116. The barbed portion 116 may be connected to the plate 404 via an adhesive or by stitching (e.g., the barbed portion 116 may be stitched to the plate 404). The plate 404 may in turn be connected to a connector 406 that includes a bead 408. The connector 406 may in turn be connected to the clip 400 to secure the barbed portion 116 to the clip 400, which is connected to the wire mesh structure 90. The connector 406 extends through a slot 407 in a gasket 50 that includes the wire mesh structure 90.

[0085] Once installed, the plate 404 may engage the exterior 410 of the wire mesh structure 90. The connector 406 may be directly connected to the plate 404 and may be connected to the clip 400 via one or more second hooks 412 that extend from the clip 400. More specifically, the one or more second hooks 412 may engage the bead 408 on the connector 406. The connector may be made of a plastic material (e.g., beaded ) The clip 400 may include a series of one or more first hooks 402 and one or more second hooks 412 that are connected to each other via a spine 414 to form a rattlesnake configuration.

[0086] The loop portion 114 may be attached to Figure 5 in the same manner as described above with respect to Figure 15 the trim cover 100 (e.g., the loop portion 114 may be attached to the trim cover 100 via any adhesive, lamination, sonic welding, etc. known in the art).
