DETAILED DESCRIPTION OF THE INVENTION

[0019] Described herein are retainers for attaching covering material to a frame or structure. While the retainers described below are discussed as attaching covering material to a seat back frame, they are by no means limited thereto. Rather, embodiments of the retainers described herein can be used to attach covering material to a variety of frames or structures as desired. As such, the term "frame" as used herein can refer to a variety of structures and is not intended to be limited to the frames illustrated herein. Rather, the frame can be any structure, including, but not limited to, various rigid structures, formed boards, molded pans, rigid backings, extruded beams or tubes, molded profiles, combinations thereof, and various other structures to which covering material can be attached. Furthermore, while the drawings illustrate a seat back frame, the retainers can be attached to other seating components, such as, for example, but not limited to, a seat cushion. Alternatively, the retainers can be used in other non-seating applications for attaching covering material to a structure.

[0020] The retainers described herein generally include an edge of the covering material, a first engagement feature, and a fastening portion for supporting the second engagement feature. In certain embodiments, the retainers described herein are tool-free to install, meaning that a separate tool, such as a hammer (as previously required), is not needed or required to assemble the retainer to the seat back frame. Such tool-free installation reduces assembly time compared to conventional methods and improves worker safety (e.g., eliminating the risk of injury from a separate tool). The retainers described herein can be assembled by hand and are ergonomically designed, which improves manufacturing efficiency compared to conventional methods.

[0021] In some embodiments, the retainers described herein can optionally support the retainer and covering material on the seat back frame in an intermediate or temporary retention configuration in which the retainer is partially engaged with the seat back frame. The temporary retention configuration can support the weight of the covering material while aligning the retainer along the length of the seat back frame, thereby facilitating assembly of the retainer to the seat back frame. As a non-limiting example, an operator can position the retainer in the temporary retention configuration along the length of the seat back frame and then ensure it is positioned and / or aligned as desired before moving the retainer to the fully engaged position.

[0022] In some embodiments, the retainers described herein can be optionally moved from a temporary retention configuration to a fully engaged configuration by rotating the retainer, thereby improving ease of insertion of the retainer into the seat back frame. Optionally, rotating the retainer from the temporary retention configuration to the fully engaged configuration can allow the retainer to be inserted into the seat back frame with less insertion force compared to conventional methods. Additionally or alternatively, the retainers described herein can include an elastically deformable portion, thereby allowing the retainer to be inserted into the seat back frame with less insertion force.

[0023] The retainers described herein can improve engagement with the seat back frame in a fully engaged configuration, which can provide a more secure connection between the retainer and the seat back frame and / or can also provide an improved (e.g., uniform) appearance. By way of non-limiting example, the retainers described herein can minimize rattle between the retainer and the seat back frame by clamping a portion of the seat back frame and / or by contacting at least two different portions of the seat back frame.

[0024] Various other benefits and advantages may be realized from the systems and methods provided herein, and the above advantages should not be considered limiting.

[0025] 1 shows an example of a structure having a covering material 104. In the illustrated embodiment, the structure is a seat 100 having a seat back 102. As mentioned above, in other embodiments, the covering material 104 can be attached to other structures as desired.

[0026] The seat 100 may include one or more covering materials 104, and one or more edges of at least one of the covering materials 104 may be connected to the frame of the seat back 102 in the seam region 106 using one or more retainers (described in more detail below) (see, for example, the seat back frame 208 shown in FIGS. 2 and 3). The covering materials 104 connected to the frame via one or more retainers may be various types of covering materials and / or combinations of covering materials as desired and should not be considered limiting. In the illustrated embodiment, the seat 100 includes two covering materials 104A-104B, with the covering material 104A attached to the seat back frame using one or more retainers. The particular seat 100 shown in FIG. 1 should not be considered limiting, and the covering materials 104 may form a portion of furniture and / or other substrates to form a portion of a seat in a moving body such as a vehicle, aircraft, train, watercraft, etc., as desired.

[0027] 2-6(c) illustrate a portion of a seam region 206 of a seat 200 according to an embodiment. The seat 200 is similar to the seat 100 and includes covering material 204A-204B, and the covering material 204A can be attached to a seat back frame 208 of the seat 200 using one or more retainers 218. In FIGS. 2-6(c), the retainers 218 directly engage the seat back frame 208 to connect the covering material 204A to the seat back frame 208. However, in other embodiments, the retainers 218 can engage holders located within the seat back frame 208 (see, e.g., FIGS. 11(a)-11(b), 12(a)-12(d), and 14).

[0028] 2 and 3, for example, the seat back frame 208 defines a groove 210. As described in more detail below, a retainer 218 is insertable into the groove 210 to engage the seat back frame 208 and connect the covering material 204 to the seat back frame 208. Optionally, one or more protrusions 212 may extend into the groove 210. If included, the protrusions 212 may extend from the first groove wall 214 and / or the second groove wall 216. In the embodiment of FIGS. 2-6(c), at least one protrusion 212 extends from the first groove wall 214.

[0029] 4 and 5, the retainer 218 generally includes a fastening portion 220, a first engagement feature 232, and a second engagement feature 234. In some embodiments, the retainer 218 is a monolithic or integrally formed component, although this is not required in other embodiments. The retainer 218 can be constructed from a variety of suitable materials and by a variety of suitable forming techniques as desired. By way of non-limiting example, the retainer 218 can be formed by extrusion, injection molding, and / or other suitable techniques or combinations of techniques as desired. Optionally, at least a portion of the retainer 218 (e.g., the first engagement feature 232) is made of an elastically deformable material, thereby allowing that portion of the retainer 218 to be selectively deformable or compressible during assembly to the seat back frame 208.

[0030] The fastening portion 220 optionally includes an end 226 of the retainer 218. As shown in FIGS. 4 and 5, for example, the fastening portion 220 includes a surface 228 to which the edge of the sheet of covering material 204A can be secured via various suitable mechanisms or techniques. As a non-limiting example, the covering material 204A can be sewn to the surface 228. The fastening portion 220 can have various shapes or profiles as desired. Optionally, and as shown in FIG. 5, the fastening portion 220 can include a shaping feature, such as, but not limited to, a notch 230, to allow the shape of the fastening portion 220 to be adjusted as desired. In the embodiment of FIGS. 2-6(c), the shaping feature 230 can bend the fastening portion 220 from an unbent configuration (see, e.g., FIGS. 4 and 5) to a bent configuration (see, e.g., FIGS. 2, 3, and 6(a)-6(c)). Optionally, fastening portions 220 extending in at least two directions (e.g., as in the bent configurations of Figures 2, 3, and 6(a)-6(c)) can improve the appearance of covering material 204A in seam region 206.

[0031] In various embodiments, the first engagement feature 232 optionally includes an end 236 opposite the end 226 of the retainer 218. Optionally, the second engagement feature 234 is between the first engagement feature 232 and the fastening portion 220, although this is not the case in other embodiments (see, for example, FIG. 9). Optionally, the second engagement feature 234 is provided along the retainer 218 to allow a predetermined amount of the retainer 218 to be inserted into the seat back frame 208 in a fully engaged configuration (described below), resulting in a more uniform appearance of the covering material 204A.

[0032] The engagement features 232, 234 can be various suitable features or structures suitable for engagement with the seat back frame 208, such as, but not limited to, the protrusion 212 of the seat back frame 208 and / or the end 215 of the first groove wall 214. In the example shown in FIGS. 2-6(c), the first engagement feature 232 is a hook feature 233 and the second engagement feature 234 is a protrusion 235. Other non-limiting embodiments of the first engagement feature 232 and / or the second engagement feature 234 include U-shaped features, T-shaped features, hook features of other profiles or shapes, protrusions of other profiles or shapes, etc. In some embodiments, as shown in FIGS. 2-10 and 12(a)-12(d), the engagement features 232, 234 can be on and / or extend from the same side of the retainer 218. In other embodiments, and as shown in Figures 11(a)-11(b) and 13(a)-16(b), the engagement features 232, 234 may be on and / or extend from both sides of the retainer 218.

[0033] The first engagement feature 232 and the second engagement feature 234 can engage different portions of the seat back frame 208 in a fully engaged configuration (see, e.g., FIG. 6(c) ) to attach the retainer 218 to the seat back frame 208. Optionally, as shown in FIG. 6(c) , in the fully engaged configuration, a portion of the seat back frame 208 is sandwiched and / or held between the first engagement feature 232 and the second engagement feature 234. As a non-limiting example, the protrusion 212 and the end 215 of the first groove wall 214 are sandwiched and / or surrounded by the first and second engagement features 232, 234. Such a sandwiching engagement can improve the connection between the retainer 218 and the seat back frame 208 and can reduce and / or eliminate rattle of the retainer 218 relative to the seat back frame 208 when fully assembled. In other embodiments, the first and second engagement features 232, 234 do not need to clamp the seat back frame 208 to attach the retainer to the seat back frame (see, for example, Figures 10, 11(a)-11(b), 12(a)-12(d), and 14).

[0034] Referring to FIG. 6(a), the first engagement feature 232 can optionally place the retainer 218 in a temporary engagement configuration relative to the seat back frame 208. Optionally, in the temporary engagement configuration, the first engagement feature 232 may engage a portion of the frame that the second engagement feature 234 engages in the full engagement configuration. As a non-limiting example, in FIG. 6(a), the first engagement feature 232 engages the end 215 of the first channel wall 214 in the temporary engagement configuration. In other embodiments, the first engagement feature 232 may engage other portions of the seat back frame 208 in the temporary engagement configuration (see, for example, FIGS. 11(a)-11(b) and 12(a)-12(d)).

[0035] In the temporary engagement configuration, the retainer 218 may engage the seat back frame 208 while supporting the weight of the covering material 204A. Such a configuration may facilitate assembly by allowing an operator to temporarily place (e.g., ensure alignment, etc.) the covering material 204A on the seat back frame 208 without having to support the covering material 204A and / or fully engage the retainer 218 with the seat back frame 208. In various embodiments, starting with the temporary engagement configuration may improve ease of insertion of the retainer 218 into the seat back frame 208 (e.g., reduce the required insertion force). As a non-limiting example, and with reference to Figures 6(a)-6(c), the retainer 218 can be rotated (indicated by arrow 238) from a temporary engagement position prior to application of an insertion force (indicated by arrow 240) to move the retainer 218 to a fully engaged configuration (shown in Figure 6(c)) such that both the first engagement feature 232 and the second engagement feature 234 engage the seat back frame 208.

[0036] 7 illustrates another example of a retainer 718, according to an embodiment, showing a fully engaged configuration with respect to a seat back frame 208. Retainer 718 is similar to retainer 218, except that first engagement feature 232 is a hook feature 733 with a different profile, and second engagement feature 234 is a hook feature 735. Retainer 718 engages two portions of frame 208 within the areas circled in red and blue. Similar to retainer 218, retainer 718 clamps frame 208 in a fully engaged configuration.

[0037] FIG. 8 illustrates another example of a retainer 818, according to an embodiment, showing a fully engaged configuration with respect to a seat back frame 208. Retainer 818 is similar to retainer 718 in that the first engagement feature 232 is a hook feature 733. Compared to retainer 718, the second engagement feature 234 of retainer 818 is a hook feature 835 with a different profile. Retainer 818 engages two portions of frame 208 within the areas surrounded by the red and blue circles. Similar to retainers 218 and 718, retainer 818 clamps frame 208 in a fully engaged configuration. In one embodiment, retainer 818 with hook feature 835 allows retainer 818 to accommodate various frame thicknesses (indicated by arrow 831 in FIG. 8 ). In other words, retainer 818 may be used to attach various types of covering materials, which may or may not have different thicknesses. In some embodiments, the hook feature 835 can optionally bend at least partially horizontally to accommodate various frame thicknesses.

[0038] FIG. 9 illustrates another example of a retainer 918, according to an embodiment, showing a fully engaged configuration for a seat back frame 208. For the retainer 218, the second engagement feature 234 of the retainer 918 extends from the fastening portion 220 and further extends from a hook feature 935. The first engagement feature 232 of the retainer 918 is the hook portion 733. The retainer 918 engages two portions of the frame 208 within the areas circled in red and blue. Similar to retainers 218, 718, and 918, the retainer 818 clamps the frame 208 in a fully engaged configuration. Similar to retainer 818, the retainer 918 can accommodate multiple frame thicknesses. Additionally, the hook feature 935 allows the retainer 918 to accommodate various frame heights (i.e., the vertical distance between the portion of the frame 208 circled in red and the portion of the frame 208 circled in blue). Such accommodation is indicated by arrow 931 in Figure 9. In some embodiments, hook feature 935 may optionally be at least partially vertically flexible to accommodate various frame heights.

[0039] 10 illustrates another example of a retainer 1018, according to an embodiment. The retainer 1018 is shown in a fully engaged configuration with a seat back frame 1008. The seat back frame 1008 is similar to the seat back frame 208, except that the seat back frame 1008 has a protrusion 212 extending from the second channel wall 216. The retainer 1018 is similar to the retainer 218, except that the retainer 1018 includes an optional secondary engagement feature 1048. If included, the secondary engagement feature 1048 may optionally engage with the protrusion 212 extending from the second channel wall 216. In this embodiment, the retainer 1018 may have at least three contact points between the retainer 1018 and the seat back frame 1008 (e.g., contact between the first engagement feature 232 and the seat back frame 1008, contact between the second engagement feature 234 and the seat back frame 1008, and contact between the protrusion 212 and the retainer 1018), which can further improve the engagement between the retainer 1018 and the seat back frame 1008.

[0040] 11(a)-11(b) illustrate another example of a retainer 1118 according to an embodiment. In FIG. 11(b), the retainer 1118 is shown in a fully engaged configuration with the seat back frame 1008. The retainer 1118 is similar to the retainer 218, except that the profile of the fastening portion 220 of the retainer 1118 is different, the first engagement feature 232 of the retainer 1118 has a hook feature 1133 facing in the opposite direction to that of the retainer 218, and the second engagement feature 234 is a hook feature 1135. In the example of FIGS. 11(a)-11(b), the opposing hook feature 1133, like the first engagement feature 232, can engage with the protrusion 212 of the second groove wall 216. 11(a)-11(b), a portion of the retainer 1118, such as, for example, but not limited to, the first engagement feature 232, may be resiliently deformable such that the portion of the retainer 1118 is selectively movable between a compressed configuration (FIG. 11(a)) and an uncompressed configuration (FIG. 11(b)). If included, the resiliently deformable portion of the retainer 1118 can facilitate engagement between the retainer 1118 and the seat back frame 1008.

[0041] 12(a) to 12(d) show another example of a retainer 1218 according to an embodiment. Compared to the retainer 218 that directly engages with the seat back frame 208, the retainer 1218 engages with a holder 1242 located within the seat back frame 208. The retainer 1218 is similar to the retainer 218 except that the fixing portion 220 extends in one direction. Furthermore, compared to the retainer 218, the hook function portion 1233 serving as the first engagement function portion 232 extends from the outermost range of the protrusion portion 1235 serving as the second engagement function portion 234.

[0042] The holder 1242 generally includes a receiving area 1244 defined at least in part by holder extensions 1246, 1248. Optionally, the holder extensions 1246, 1248 may include features, such as, but not limited to, curved surfaces, that facilitate movement of the retainer 1218 relative to the holder 1242 during assembly. Optionally, the holder 1242 may include a fastening portion 1250 for attaching a covering material, such as covering material 204B. The particular shapes of the holder 1242, receiving area 1244, extensions 1246, 1248, and / or fastening portion 1250 should not be considered limiting to this disclosure. The holder 1242 can be attached or secured to the seat back frame 208 using various techniques or mechanisms, as desired.

[0043] A method of assembling the retainer 1218 to the seat back frame 208 may include positioning the retainer 1218 in a temporary retention configuration by partially inserting the retainer 1218 into the receiving area 1244, thereby engaging the first engagement feature 232 with the holder extension 1246 ( FIG. 12( b)). To move the retainer 1218 from the temporary retention configuration to the fully engaged configuration, the method may include optionally rotating the retainer 1218, thereby engaging the first engagement feature 232 with the holder extension 1248 and engaging the second engagement feature 234 with the holder extension 1246, as shown in FIG. 12( c). The method may include applying an insertion force (represented by arrow 1240 in FIG. 12( c)) to the retainer 1218 to move the retainer 1218 to the fully engaged configuration as shown in FIG. 12( d). In one embodiment, in the fully engaged configuration, the engagement features 232 , 234 are both at least partially within the receiving area 1244 and / or such that the engagement features 232 , 234 engage the holder extensions 1246 , 1248 within the receiving area 1244 .

[0044] FIGS. 13(a)-13(c) show another example of a retainer 1318 according to an embodiment.
