DETAILED DESCRIPTION

[0033] The subject matter of embodiments of the present invention is described here with specificity to meet statutory requirements, but this description is not necessarily intended to limit the scope of the claims. The claimed subject matter may be embodied in other ways, may include different elements or steps, and may be used in conjunction with other existing or future technologies. This description should not be interpreted as implying any particular order or arrangement among or between various steps or elements except when the order of individual steps or arrangement of elements is explicitly described. Directional references such as "up," "down," "top," "left," "right," "front," and "back," among others are intended to refer to the orientation as illustrated and described in the figure (or figures) to which the components and directions are referencing.

[0034] In one aspect, disclosed is a slider cover for sliders for a fastening tape that is curved and/or extends in at least two planes, and associated methods, systems, devices, and other apparatuses. The slider cover includes a body having a first end and a second end that are arranged in a direction of travel of the slider cover. The slider cover also includes a first slider- receiving area and a second slider-receiving area. The first slider-receiving area includes a centerline extending at a non-parallel angle with respect to a horizontal plane of the slider cover. The second slider-receiving area includes a centerline extending at a non-parallel angle with respect to the horizontal plane of the slider cover. According to certain examples, a slider cover assembly includes the slider cover, a first slider retained by the first slider-receiving area, and a second slider retained by the second slider-receiving area.

[0035] FIGS. 1-8 illustrate an example of a slider cover 100. The slider cover 100 includes a body 102 having a first end 104 and a second end 106. The first end 104 and the second end 106 are arranged in a direction of travel of the slider cover 100. A top surface 108 extends from the first end 104 to the second end 106. A middle portion 110 of the body 102 is between the first end 104 and the second end 106. In some examples, the top surface 108 at the middle portion 110 is elevated relative to the first end 104 and the second end 106 (see FIG. 2). In certain examples, the top surface 108 and/or a bottom surface 138 of the body 102 are arcuate shaped, although they need not be.

[0036] As best illustrated in FIGS. 2 and 6, in various examples, the body 102 includes a taper or continuous radius 112A between the middle portion 110 and the first end 104. The taper or continuous radius 112A extends to the first end 104 such that a thickness of the body 102 at the first end 104 is less than a thickness of the body 102 at the middle portion 110. Similarly, in some examples, the body 102 includes a taper or continuous radius 112B between the middle portion 110 and the second end 106. The taper or continuous radius 112B extends to the second end 106 such that a thickness of the body 102 at the second end 106 is less than the thickness of the body 102 at the middle portion 110. In various examples, the thickness of the body 102 at the first end 104 is the same as the thickness of the body 102 at the second end 106, although it need not be. Through the taper or continuous radius 112A and/or the taper or continuous radius 112B, at least a portion of the slider cover 100 on a fastening tape can dive under a fabric to bring the middle portion 110 closer to the fabric. For example, FIG. 24 illustrates a non-limiting example of how the taper or continuous radius 112B allows a portion of the slider cover 100 to dive under a seam 2600 of a fabric 2602 covering a fastening tape 2604. In other cases, tapers or continuous radii 112A-112B are not present and the thickness of the first end 104 and the second end 106 is generally the same as the thickness of the middle portion 110.

[0037] In various examples, the slider cover 100 includes a first slider-receiving portion 114A between the middle portion 110 and the first end 104 and a second slider-receiving portion 114B between the middle portion 1 10 and the second end 106. The first slider-receiving portion defines a first slider-receiving area 116A, and the second slider-receiving portion 114B defines a second slider-receiving area 116B. As described in detail below, the first slider- receiving portion 114A is configured to retain a first slider and the second slider-receiving portion 114B is configured to retain a second slider.

[0038] As illustrated in FIG. 2, the first slider-receiving portion 114A includes a centerline 118A extending at an angle with respect to a horizontal plane 120 of the slider cover 100. As illustrated in FIG. 2, the horizontal plane 120 can be a plane that is tangent to the top surface 108 at the center of the middle portion 110. In a similar manner, the second slider-receiving portion 114B includes a centerline 118B extending at an angle with respect to the horizontal plane 120 of the slider cover 100. In various examples, the angles are non-zero angles such that the centerlines 118A-B of the respective slider-receiving portions 114A-B are not parallel to the horizontal plane 120. In some examples, the angles between the centerlines 118A-B and the horizontal plane 120 are from about 0 "to about 90 °. In various cases, the angles between the centerlines 118A-B and the horizontal plane 120 are about 45 °. In other examples, the angles between the centerlines 118A-B and the horizontal plane 120 are less than 45 °. In other examples, the angles between the centerlines 1 18A-B and the horizontal plane 120 may be varied or selected depending on a path of a fastening tape on which the slider cover 100 is installed. In various examples, the centerlines 118A-B intersect one another within the body 102, such as within the middle portion 110 of the body 102, although they need not. In some examples, the centerlines 118A-B each intersect the top surface 108 of the body 102, although they need not. In some examples, the angles between the centerlines 118A-B and the horizontal plane 120 are substantially the same, although they need not be. In some examples, the slider-receiving portions 114A-B are positioned symmetrically with respect to a shaft opening 136 at the center of the body 102. In other examples, depending on the movable range of the shaft that extends through the shaft opening 136 (see, e.g., FIG. 19), the curvature of the shaft, and/or the mechanism of the shaft, the slider-receiving portions 114A-B may be asymmetrical.

[0039] Referring to FIGS. 1 and 4-6, the slider-receiving portions 114A-B each include a locking slot 124A-B or similar locking feature. The locking slots 124A-B engage with portions of sliders to retain the sliders in the slider-receiving areas 116A-B (see FIGS. 8, 9 and 11-14). In various examples, the locking slots 124A-B limit movement of sliders in an x-direction 129 and a y-direction 131 (see FIG. 4) while allowing for rotation or tilting of the sliders. In certain cases, each locking slot 124A-B guides installation of the slider from a single direction (e.g., from an end of the slider cover assembly) during assembly of a slider cover assembly 800 (see FIGS. 8-14).

[0040] In some optional examples, each locking slot 124A-B includes one or more locking tabs 126. In various examples, the locking tabs 126 provide a snap-fit connection with the sliders in the slider-receiving areas 116A-B. In certain cases, the locking tabs 126 define a rotation axis for the sliders such that the sliders can rotate within the slider-receiving areas 116A-B relative to the slider cover 100. In various examples, the locking tabs 126 provide an alert or indication that a slider is positioned within the respective slider-receiving area 116A- B. As one non-limiting example, the alert or indication may be an audible alert, such as a click, pop, snap, etc. Various other types of audible alerts or other alerts or indications may be provided. In some examples, various other securing mechanisms may be used to retain the sliders within the slider-receiving areas 116A-B, including, but not limited to, pins, bolts, clips, clasps, hooks, loops, screws, or various other suitable securing mechanisms.

[0041] Referring to FIG. 3, in some examples, the middle portion 110 has a width 128 that is greater than a width 130 of the first end 104 and the second end 106 of the body 102. In certain cases, the body 102 includes a first side 132 that extends from the first end 104 to the second end 106, and a second side 134 opposite the first side 132. As illustrated in FIG. 3, in various optional examples, the first side 132 and the second side 134 at the middle portion 110 are arcuate shaped, although they need not be.

[0042] In certain examples, the middle portion 110 defines the shaft opening 136 extending through the body 102 from the top surface 108 to the bottom surface 138 of the body 102. In some examples, the shaft opening 136 is tapered such that the shaft opening 136 increases or decreases in size as it extends from the top surface 108 to the bottom surface 138 (see FIG. 6). As one non-limiting example, the shaft opening 136 may be tapered when the shaft to be accommodated within the shaft opening 136 is not straight or is off-center from a rotation point of the shaft. In other examples, the shaft opening 136 is not tapered. For example, in one non-limiting case, the shaft opening 136 may be cylindrically shaped. The shape and size of the shaft opening 136 may be varied depending on a shape and size of a shaft that the shaft opening 136 is configured to accommodate.

[0043] As illustrated in FIGS. 1 , 2, 5, and 7, the body 102 of the slider cover 100 defines a first guiding channel 140A and a second guiding channel 140B. The guiding channels 140A- B guide zipper elements of a fastening tape as the slider cover 100 is positioned and moved along the fastening tape. In some examples, as illustrated in FIG. 5, a portion 142A of the first side 132 between the first guiding channel 140A and the bottom surface 138 is arcuate shaped and a portion 142B of the second side 134 between the second guiding channel 140B and the bottom surface 138 is arcuate shaped. In certain examples, these arcuate shaped portions 142A-B minimize an interference between the disengaged (opened) zipper elements of the fastener tape and the slider cover 100 to guide the elements in a more natural direction, which facilitates the smooth opening and closing of the zipper elements (e.g., the elements may fit along the curved surfaces). In other examples, the portions 142A-B may not be arcuate shaped and may have any shape as desired. In some examples, the guiding channels 140A- B extend from the first end 104 to the second end 106. In other examples, the guiding channels 140A-B extend from the first slider-receiving portion 114A to the second slider-receiving portion 114B.

[0044] FIGS. 8-14 illustrate an example of the slider cover assembly 800 that includes the slider cover 100, a first slider 802A, and a second slider 802B. The first slider 802A is retained within the first slider-receiving area 116A and the second slider 802B is retained within the second slider-receiving area 116B. As illustrated in FIGS. 13 and 14, the first slider-receiving area 1 16A defines a clearance 804A between the first slider 802A and the body 102 when the first slider 802A is positioned within the first slider-receiving area 116A. Through the clearance 804A, the first slider 802A can rotate or tilt a predetermined amount about a rotation axis (e.g., defined by the locking tabs 126) while retained within the first slider-receiving area 116A. The second slider-receiving area 116B includes a similar clearance 804B such that the second slider 802B can rotate or tilt while retained within the second slider-receiving area 116B. In various optional examples, a cutout, groove, channel, or other similar feature defined in the body 102 may provide the clearances 804A-B. The rotatably supported sliders 802A-B provide flexibility to the angles of the centerlines 1 18A-B such that the slider cover assembly 800 can move along fastening tapes extending at various angles relative to the horizontal plane 120, even if those angles do not exactly match the angles of the centerlines 118A-B.

[0045] FIGS. 15-18 illustrate the slider cover assembly 800 on a fastening tape 1700 that includes zipper elements 1702. As illustrated in FIG. 15, the fastening tape 1700 is curved in a z-direction such that portions of the fastening tape 1700 extend in at least two planes. In various examples, the angled slider-receiving areas 116A-B (and optionally the tilting of the sliders 802A-B) allow the slider cover assembly 800 to smoothly open and close the zipper elements 1702 as the slider cover assembly 800 moves along the fastening tape 1700.

[0046] In various examples, the sliders 802A-B are arranged such that during movement along the fastening tape 1700, one slider closes the zipper elements 1702, the other slider opens the zipper elements 1702, and the middle portion 110 of the slider cover 100 maintains an opening through the fastening tape 1700 between the sliders 802A-B. FIGS. 16-18 illustrate the guiding channels 140A-B guiding the fastening tape 1700 and zipper elements 1702 and the slider cover 100 opening the zipper elements 1702 to create the opening in the fastening tape 1700 (e.g., to receive a shaft or other component).

[0047] FIG. 19 illustrates the slider cover assembly 800 with a shaft 2100 extending through the shaft opening 136. In various examples, the shaft 2100 may be a component of a headrest frame 2302 for a passenger seat 2300 (see FIG. 21). In other examples, the shaft 2100 may be a component of various other items or devices that need to extend through the fastening tape 1700 and be movable along the fastening tape 1700.

[0048] FIG. 20 illustrates the slider cover assembly 800 assembled on another fastening tape 2200. As illustrated in FIG. 20, the fastening tape 2200 generally includes a first portion 2202 extending in a first plane and a second portion 2204 extending in a second plane, and a curved portion 2206 between the first portion 2202 and the second portion 2204.

[0049] FIGS. 21-23 illustrate an example of slider cover assemblies 800 on two fastening tapes 2200 on a portion of the passenger seat 2300. The shafts 2100 form portions of the headrest frame 2302 and extend through the slider covers 100 (and through the openings in the fastening tapes 2200 created by the slider covers 100). Through the slider cover assemblies 800, the headrest frame 2302 is movable to various positions relative to the passenger seat 2300, including along curved portions, while the remaining portions of the fastenings tapes 2200 are closed.

[0050] FIG. 24 illustrates an example of how the taper or continuous radius 112B allows a portion of the slider cover 100 to dive under the seam 2600 of the fabric 2602 covering the fastening tape 2604.
