Description

[0001] Positioning and Stabilising Structure for Eye Mask

[0002] Technical Field

[0003] The present invention relates, in general terms, to a positioning and stabilising structure for an eye mask.

[0004] Background

[0005] Sleep is an important component to an individual's wellbeing, growth and vitality. It is also important in today's overstimulated and highly stressed world. In particular, maintaining the wholeness and wholesomeness of the sleep / wake cycle day-to-day and month-to-month is essential to preserve personal well-being and happiness as well as the productivity and good order of society at large. Ideally, the rhythm of the sleep / wake cycle would be governed by the natural order of each day's sunrise and sunset. The artificial routines of modern personal and social life, however, have eclipsed the rhythms of nature making it more difficult to wake up and go to sleep at appointed times the more the exigencies of one's own routines are in conflict with the natural cycle of things.

[0006] Eye masks with a light-tight design which provides a condition of total darkness are known to help stimulate melatonin production and thus serve to promote a state of sleep. However, current eye masks may be uncomfortable, especially for a side sleeper, or too heavy or cumbersome to use.

[0007] Certain eye masks may be uncomfortable or impractical, for example, if used for prolonged time periods. Certain eye masks can be complicated for users to attach and to correctly position on the head for effective use.

[0008] As a consequence of these challenges, some eye masks suffer from being one or more of obtrusive, aesthetically undesirable, costly, poorly fitting, difficult to use, and uncomfortable especially when worn for long periods of time or when a user is unfamiliar with a system.

[0009] It would be desirable to overcome or ameliorate at least one of the above-described problems, or at least to provide a useful alternative. Summary

[0090] Eye Mask

[0091] The eye mask in accordance with one aspect of the present technology comprises the following functional aspects: an eye component positionable over at least orbital regions of a face of a user and configured to block light to eyes of the user, a face-contacting structure connected to or contiguous with the eye component. A positioning and stabilising structure for retaining the eye mask on the user's face is attachable to the eye mask. In some forms a functional aspect may be provided by one or more physical components. In some forms, one physical component may provide one or more functional aspects. In use, the eye component blocks out light to the user's eyes, and the face-contacting structure may further block out any other stray light to the eyes of the user.

[0092] The eye mask in accordance with one form of the present technology is constructed and arranged to be able to provide comfort to the user in use, by blocking out light, and optionally sound. In particular, the eye mask may be geometrically sized to fit an Asian's head. The size may be calculated based on anthropological data from an Asian population.

[0093] The eye mask in accordance with one form of the present technology is constructed and arranged to be able to monitor and diagnose a sleep pattern or sleep state of a user. In some forms, the eye mask may provide a corrective output to the user based on the sleep pattern or sleep state. In some forms of the present technology, the eye mask further comprises a sensor module, a cooling module, a flip module, a noise reduction component, an imaging module, or a combination thereof.

[0094] Eye Component

[0095] At least part of the eye component may be resiliently stretchable to enable it to be readily fitted to the user's head, and to accommodate a variety of different head sizes. In some embodiments, the entirety of the eye mask may be stretchable in at least a radial direction.

[0096] In one form of the present technology, the eye component is sized to block light to the eyes of the user. In this regard, in use, the eye component is sized such that it covers at least orbital regions of a face of a user. The orbital region includes a supra-orbital region. The eye component may be configured to block light to eyes of the user. The eye component may be sized to cover more than the orbital regions of the user's face. The eye component may be sized to further cover a portion of an infra-orbital region of the user in use. The eye component may be sized to further cover a portion of a nasal region of the user. The eye component may be sized to further cover a portion of a zygomatic region of the user. The eye component may be sized to further cover a forehead of the user. An oversized eye component may double up as a pillow and provide comfort to the user.

[0097] In one form of the present technology, the eye component is sized to cover at least a portion of a frontal region, orbital regions, zygomatic region and nasal bridge of a face of a user.

[0098] In one form of the present technology, the eye mask comprises at least one cavity at a user facing side. The eye component may act in combination with the face-contacting structure to form the cavity. In this regard, the cavity may be bordered by edges of the face-contacting structure and an inner surface of the eye component. The cavity may be configured to space the eye component apart from the eyes of the user. Accordingly, an internal surface of the eye component is spaced apart from the eyes of the user during use.

[0099] The cavity may be characterised by a depth of about 1 cm to about 15 cm, about 1 cm to about 14 cm, about 1 cm to about 13 cm, about 1 cm to about 12 cm, about 1 cm to about 11 cm, about 1 cm to about 10 cm, about 2 cm to about 10 cm, about 3 cm to about 10 cm, about 4 cm to about 10 cm, about 5 cm to about 10 cm, about 6 cm to about 10 cm, about 7 cm to about 10 cm, or about 8 cm to about 10 cm. The depth of the cavity may be configured by varying the height of the face-contacting structure.

[0100] In one form of the present technology, the eye component has a curved morphology. The curved morphology may be relative to a frontal plane of the user and / or a transverse plane of the user. The curved morphology of the eye component conforms to the user's face, and provides better skin contact and light blocking. For example, the eye component may be a hyperbolic paraboloid.

[0101] In one form of the present technology, the eye component is formed as a loop or band, and the eye component is configured to loop circumferentially around a user's head.

[0102] In one form of the present technology, the eye component comprises a left section positionable over a left orbital region of the user's face and a right section positionable over a right orbital region of the user's face. The left section and right section may be similarly sized. The left and right section may be held in position relative to each other by the face-contacting structure.

[0103] In one form of the present technology, the eye component comprises at least one pocket. The pocket may be sized to house a sensor module, a cooling module, a flip module, a noise reduction component, an imaging module, or a combination thereof.

[0104] In one form of the present technology, the eye component is formed from a perforated, light blocking fabric material or composite material. The eye component may be made breathable, so as to provide comfort to the user. For example, silk, cotton or fleece may be used. The eye component may be formed from a material selected from perforated textile, breathable foam and / or fiber. Fabrics that are naturally thick and dense may also be used, such as velvet, heavy cotton, or woven jacquard. These fabrics have a tighter weave or a heavier weight, which helps to minimise the amount of light that can penetrate the material. Alternatively, a fabric composite material may be used. The composite material may be a laminated material.

[0105] In some forms of the present technology, the eye component is formed from an elastic fabric material. For example, polyester, cotton, spandex, or nylon may be used, which may be further laminated with another fabric to increase its light blocking properties.

[0106] Face-contacting Structure

[0107] The eye mask includes a face-contacting structure. Since it is in direct contact with the user's face, the shape and configuration of the face-contacting structure can have a direct impact on the effectiveness and comfort of the eye mask.

[0108] The design of a face-contacting structure presents a number of challenges. The face has a complex three-dimensional shape. The size and shape of noses and heads varies considerably between individuals. Since the head includes bone, cartilage and soft tissue, different regions of the face respond differently to mechanical forces.

[0109] One type of face-contacting structure extends around the periphery of the eye mask and is intended to seal against the user's face when force is applied to the user interface with the face-contacting structure in confronting engagement with the user's face. The face-contacting structure may include a pad made of a polyurethane (PU). With this type of face-contacting structure, there may be gaps between the face-contacting structure and the face, and additional force may be required to force the eye mask against the face in order to achieve the desired contact.

[0110] The regions not engaged at all by the face-contacting structure may allow gaps to form between the face-contacting structure and the user's face through which undesirable light pollution may ingress into the eye mask. The light pollution or "light leak" may decrease the efficacy and enjoyment of the overall immersive experience, or reduce the effectiveness of the eye mask as a sleep aid, for the user. In addition, previous systems may be difficult to adjust to enable application for a wide variety of head sizes. Further still, previously known eye masks and their associated stabilizing structures may often be relatively heavy and may be difficult to clean which may thus further limit the comfort and useability of the system.

[0111] Another type of face-contacting structure incorporates a flap seal of thin material positioned about a portion of the periphery thereof so as to provide a sealing action against the face of the user. Like the previous style of face-contacting structure, if the match between the face and the face-contacting structure is not good, additional force may be required to achieve a seal, or light may leak into the eye mask in-use. Furthermore, if the shape of the face-contacting structure does not match that of the user, it may crease or buckle in-use, giving rise to undesirable light penetration.

[0112] Some face-contacting structures may be limited to engaging with regions of the user's face that protrude beyond the arc of curvature of the face engaging surface of the facecontacting structure. These regions may typically include the user's forehead and cheek bones. This may result in user discomfort at localised stress points. Other facial regions may not be engaged at all by the face-contacting structure or may only be engaged in a negligible manner that may thus be insufficient to increase the translation distance of the clamping pressure. These regions may typically include the sides of the user's face, or the region adjacent and surrounding the user's nose. To the extent to which there is a mismatch between the shape of the users' face and the face-contacting structure, it is advantageous for the face-contacting structure or a related component to be adaptable in order for an appropriate contact or other relationship to form.

[0113] In one form of the present technology, the face-contacting structure provides a target interfacing region, and may additionally provide a cushioning function. The target interfacing region is a region on the face-contacting structure where contact of the facecontacting structure with the user's face may occur. The region where contact actually occurs may change within a given sleep session, from day to day, and from user to user, depending on a range of factors including for example, where the eye mask was placed on the face, tension in the positioning and stabilising structure and the shape of a user's face.

[0114] The face-contacting structure is connected to or contiguous with the eye component. The face-contacting structure acts together with the eye component to block out light to the user's eyes. For example, the face-contacting structure may be laminated to the eye component.

[0115] In one form of the present technology, the face-contacting structure is configured to contact at least the orbital regions of the user's face. The face-contacting structure may also contact eyes of the user, providing slight pressure on the eyes to aid sleep.

[0116] In one form of the present technology, the face-contacting structure is configured to contact a supra-orbital region of the user's face. The face-contacting structure may be formed to contact more than the orbital regions of the user's face. The face-contacting structure may further contact an infra-orbital region of the user. The face-contacting structure may further contact a portion of a nasal region of the user. In this regard, the face-contacting structure may overlap a nose bridge region or on a nose-ridge region of the user's face. The face-contacting structure may further contact a portion of a zygomatic region of the user's head. The face-contacting structure may further contact a forehead of the user. In one form of the present technology, the face-contacting structure is configured to surround at least the orbital regions of the user's face. The face-contacting structure may comprise at least one orifice for housing an eye of the user. In this regard, while the eye mask obstructs light to the eyes, the eye mask does not contact the orbital regions and eyes of the user.

[0117] In one form of the present technology, the face-contacting structure is configured to surround a supra-orbital region of the user's face. The face-contacting structure may be formed to surround more than the orbital regions of the user's face. The face-contacting structure may further surround an infra-orbital region of the user. The face-contacting structure may further surround a portion of a nasal region of the user. The facecontacting structure may further surround a portion of a zygomatic region of the user's head. The face-contacting structure may further surround a forehead of the user.

[0118] In one form of the present technology, the face-contacting structure is sized to contact at least a portion of a frontal region, orbital regions, zygomatic region and nasal bridge of a face of a user.

[0119] In one form of the present technology, the face-contacting structure is characterised by a height of about 1 cm to about 15 cm, about 1 cm to about 14 cm, about 1 cm to about 13 cm, about 1 cm to about 12 cm, about 1 cm to about 11 cm, about 1 cm to about

[0120] 10 cm, about 2 cm to about 10 cm, about 3 cm to about 10 cm, about 4 cm to about

[0121] 10 cm, about 5 cm to about 10 cm, about 6 cm to about 10 cm, about 7 cm to about

[0122] 10 cm, or about 8 cm to about 10 cm. The height of the face-contacting structure may create a cavity such that the eyes of the user are spaced apart from the eye component.

[0123] In one form of the present technology, the face-contacting structure comprises a bridge portion or a saddle-shaped region for saddling the nasal region of the user's face. The bridge portion saddles between the left and right orbital sections of the eye component. The bridge portion may be constructed to form a seal in use on a nose bridge region or on a nose-ridge region of the user's face. The bridge portion may be made of a different material (for example, a stiffer material) than the rest of the face-contacting structure to provide stability to the eye mask when used. For example, the bridge portion may be a thermoformed material.

[0124] In one form of the present technology, the bridge portion is formed as a single entity. In this regard, the bridge portion is formed by curving the material such that it forms a parabola. In one form of the present technology, the bridge portion is characterised by a height to width ratio of about 1 : 1 to about 5: 1, about 1 : 1 to about 4: 1, about 1: 1 to about 3: 1, about 1 : 1 to about 2: 1, or about 1.5: 1 to about 2: 1.

[0125] In one form of the present technology, the face-contacting structure is contoured to conform to the user's face. For example, the face-contacting structure may be a hyperbolic paraboloid.

[0126] In one form of the present technology, the face-contacting structure is substantially similarly sized to, or smaller than the eye component. In this regard, the face-contacting structure is not visible when the eye mask is worn. For example, when the eye component and the face-contacting structure together form a loop or a band, the facecontacting structure may not be visible when the eye mask is worn.

[0127] In one form of the present technology, the face-contacting structure is larger than the eye component. The face-contacting structure may form a border surrounding the eye component. Further, portions of the face-contacting structure may be visible when the eye mask is worn. For example, when the eye component comprises left and right orbital sections, a bridge portion of the face-contacting structure may be exposed and visible when the eye mask is worn.

[0128] In certain forms of the present technology, the face-contacting structure is constructed from a biocompatible material, e.g. silicone rubber. The face-contacting structure may be constructed from a soft, flexible, resilient material such as silicone. The facecontacting structure may be constructed from a breathable foam. The foam may have a thickness of about 1 cm to about 10 cm. The face-contacting structure may have a gradient of decreasing thickness towards an orifice configured to house an eye of the user in order to improve the breathability of the eye mask. The face-contacting structure may further be perforated to increase the breathability of the eye mask.

[0129] In other forms of the present technology, the face-contacting structure is constructed from a perforated, light blocking fabric material or composite material. The facecontacting structure may be made breathable, so as to provide comfort to the user. The face-contacting structure may be formed from a material selected from perforated textile, breathable foam and / or fiber. Fabrics that are naturally thick and dense may also be used, such as velvet, heavy cotton, or woven jacquard. These fabrics have a tighter weave or a heavier weight, which helps to minimise the amount of light that can penetrate the material. Alternatively, a fabric composite material may be used. The composite material may be a laminated material.

[0130] In some forms of the present technology, the face-contacting structure is formed from an elastic fabric material. For example, polyester, cotton, spandex, or nylon may be used, which may be further laminated with another fabric to increase it light blocking property.

[0131] In one form of the present technology, the face-contacting structure is constructed from a composite material. The composite material may comprise an external fabric (or fabric composite) layer surrounding an inner foam. The fabric layer may be thermoformed with the foam. For example, the fabric may be laminated to one or all sides of foam and placed in a 2-piece mold. Heat and pressure are then applied, which permanently molds the laminate into a semi-rigid product. The foam may be a memory foam, high density foam, low density foam, or a combination thereof. The foam may be selected from silicone, polyester, polycarbonate, polyethylene, polypropylene, polystyrene, polyurethane, nylon, thermoplastic elastomer, polycarbonate-acrylonitrile butadiene sytene (PC-ABS), polyethylene terephthalate (PET), latex, or a combination thereof. For example, memory foam may be used, which comprises polyurethane with chemicals that increase its viscosity and density. It is often referred to as "viscoelastic" polyurethane foam, or low-resilience polyurethane foam (LRPu).

[0132] The foam may have a cell structure that reacts to body heat and weight, helping relieve pressure points, preventing pressure sores, and the like. The density and layer thickness of the foam may provide a different feel to the user. A high-density foam may have better compression ratings over the life of the eye mask. A lower-density one will generally have slightly shorter life due to the compression that takes place after repeated use. Cell structures can vary from very open to almost closed cell. The open cell foam structure includes a plurality of interconnected cells, wherein the windows between the adjacent cells are broken and / or removed. In contrast, a closed cell foam has substantially no interconnected cells and the windows between the adjacent cells are substantially intact. The tighter the cell structure, the less airflow through the foam. Breathable foam will have a more open cell structure, allowing higher airflow, better recovery, and lower odour retention.

[0133] In one form of the present technology, the foam comprises an open cellular structure.

[0134] The cellular structure may be about 10 cells to about 40 cells per inch, about 15 cells to about 40 cells per inch, about 20 cells to about 40 cells per inch, about 25 cells to about 40 cells per inch, or about 30 cells to about 40 cells per inch.

[0135] In one form of the present technology, the foam is characterised by a hardness of about 35 pounds-force to about 100 pounds-force, about 35 pounds-force to about 90 pounds- force, about 35 pounds-force to about 80 pounds-force, about 35 pounds-force to about 70 pounds-force, about 35 pounds-force to about 60 pounds-force, or about 35 pounds- force to about 50 pounds-force.

[0136] In one form of the present technology, the foam is characterised by a density of about 1.2 pounds per cubic foot to about 2.0 pounds per cubic foot, about 1.2 pounds per cubic foot to about 1.8 pounds per cubic foot, or about 1.2 pounds per cubic foot to about 1.6 pounds per cubic foot.

[0137] In one form of the present technology, the composite material comprises at least one air pocket. The air pocket may be between the external fabric and the inner foam. This may be formed by, for example, laminating a side of the foam to the fabric and providing an excess of fabric to obtain a loose fit around the foam when thermoforming. It was found that the air pocket provides flexibility during use, in that the eye mask is able to further conform to an individual's facial contours without excessive pressure. The air pocket also increases the surface area of contact of the external fabric with the user's face, thus providing better light blocking and stability during use.

[0138] In one form of the present technology, the composite material is characterised by a cross-sectional area, wherein the air pocket is about 1% to about 30%. In other forms of the present technology, the cross-sectional area of the air pocket relative to the composite material is about 5% to about 30%, about 10% to about 30%, about 12% to about 30%, about 14% to about 30%, or about 15% to about 30%.

[0139] Positioning and Stabilising Structure

[0140] The eye mask may comprise a positioning and stabilizing structure for retaining the eye mask on the user's head. The positioning and stabilising structure may be removable from the eye mask. The positioning and stabilizing structure may be responsible for providing forces to counter gravitational forces of the eye component and / or facecontacting structure. In the past such structures have comprised rigid structures that are typically applied to the head under tension to maintain the eye mask in its operational position. Such systems have been prone to exert a clamping pressure on the user's face which can result in user discomfort at localised stress points. Also, previous eye masks may be difficult to adjust to allow wide application to different head sizes. Further, known eye masks may be heavy and difficult to clean, which further limits the comfort and useability.

[0141] The face-contacting structure of the eye mask of the present technology may be held in a contact position in use by the positioning and stabilising structure.

[0142] In one form the positioning and stabilising structure provides a retention force at least sufficient to hold the eye mask in contact with the user's face.

[0143] In one form the positioning and stabilising structure provides a retention force to overcome the effect of the gravitational force on the eye mask.

[0144] In one form the positioning and stabilising structure provides a retention force as a safety margin to overcome the potential effect of disrupting forces on the eye mask, such as from accidental interference with the eye mask.

[0145] In one form of the present technology, a positioning and stabilising structure is provided that is configured in a manner consistent with being worn by a user while sleeping. In one example the positioning and stabilising structure has a low profile, or low cross- sectional thickness, to reduce the perceived or actual bulk of the apparatus. In one example, the positioning and stabilising structure comprises at least one strap having a rectangular cross-section. In one example the positioning and stabilising structure comprises at least one flat strap.

[0146] In one form of the present technology, the positioning and stabilising structure is configured so as not to be too large and bulky to prevent the user from lying in a supine sleeping position with a back region of the user's head on a pillow.

[0147] In one form of the present technology, the positioning and stabilising structure is configured so as not to be too large and bulky to prevent the user from lying in a side sleeping position with a side region of the user's head on a pillow.

[0148] In one form of the present technology, the positioning and stabilising structure has a width substantially similar to the eye component. In other forms of the present technology, the positioning and stabilising structure has a width smaller than a width of the eye component.

[0149] For example, the positioning and stabilising structure may have a width of about 10 mm to about 100 mm, about 10 mm to about 90 mm, about 10 mm to about 80 mm, about 10 mm to about 70 mm, about 10 mm to about 60 mm, about 10 mm to about 50 mm, or about 10 mm to about 40 mm. The positioning and stabilising structure may have a thickness of about 1 mm to about 100 mm.

[0150] For example, the positioning and stabilising structure may have a length of about 100 mm to about 800 mm, about 100 mm to about 750 mm, about 100 mm to about 700 mm, about 100 mm to about 650 mm, about 100 mm to about 600 mm, about 100 mm to about 550 mm, about 100 mm to about 500 mm, about 100 mm to about 450 mm, or about 100 mm to about 400 mm.

[0151] The positioning and stabilising structure is attached to the eye component, and provides a resilient force such that the face-contacting structure is pressured against the user's face. For example, the positioning and stabilising structure may be attached to opposed ends of the eye component. Alternatively, the positioning and stabilising structure may form a loop or band circumferentially positionable on a user's head.

[0152] In one form of the present technology, the positioning and stabilising structure is formed as a flexible headband circumferentially positionable on a user's head. The eye component may be attached to at least a portion of the band along its length, or at least to a face facing portion of the band. Alternatively, the eye component may be circumferentially attached to the band along its whole length or is a portion of the circumferential band. In this regard, the positioning and stabilising structure is contiguous with the eye component such that the eye mask may be worn as a headband on a user's head when not in use.

[0153] The positioning and stabilising structure may overlay at least an otobasion superior region of the user's head in use. The positioning and stabilising structure may be configured to overlay an otobasion superior region and otobasion inferior region of the user's head in use. In this regard, the ears of the user may be covered. This may reduce noise to the user.

[0154] In one form of the present technology, a positioning and stabilising structure comprises a strap. The eye component may be attached to the positioning and stabilising structure at its ends thereof. The strap may be constructed from a laminate of a fabric usercontacting layer, a foam inner layer and a fabric outer layer. In one form, the foam is porous to allow moisture, (e.g., sweat), to pass through the strap. Alternatively or in addition, the strap may comprise fiberfill (for example, polyester fiberfill), non-woven padding, foam padding, high density upholstery foam, compressed polyester, medium density polyurethane antimicrobial foam, high density polyurethane foam, dry fast open cell foam, or a combination thereof. Consequently, the strap is not too large and bulky to prevent the user from lying in the side sleeping position. In addition, the strap is extensible and soft.

[0155] In one form of the present technology, the positioning and stabilising structure comprises a strap that is extensible, e.g. resiliently extensible. For example the strap may be configured in use to be in tension. The positioning and stabilising structure may comprise adjustable means for extending the strap. In one form of the present technology, the positioning and stabilising structure comprises a left strap, a right strap and a connector. The connector may be a buckle.

[0156] In one form of the present technology, one or more rigidizers may be provided to selectively alter the rigidity of the positioning and stabilising structure. These may be attached to an external surface of the fabric, or inserted within the fabric layers. For example, the rigidizer may be laminated to or embedded between fabric layers. Thermoset yarns may be used to provide selective rigidification. The textile may also be rigidized at other parts of the positioning and stabilising structure, such as along side sections that will contact the user's face in use, for example using a coating, a laminate, a rigidized thread sewn into the textile, or any similar means.

[0157] The rigidizers may be semi-rigid. In other words, the rigidizers may be more rigid than the textile material used to form the positioning and stabilising structure, but not completely rigid. In this way, they are capable of providing structure to the positioning and stabilising structure, but are flexible so that they are capable of being bent. A user and / or medical professional may adjust or bend the rigidizers in order to provide tailored support for an individual user. The rigidizers also may begin semi-rigid (in other words, the rigidizers may be semi-rigid at the beginning or initially), and may become rigid after a period of time. For example, a medical professional may adjust the shape of the rigidizers so that the positioning and stabilising structure is suited for an individual user's face. Then the rigidizers may be treated (e.g., heat treated) so that they are set in their shape. In other words, the rigidity of the rigidizers is capable of changing. Consequently, the rigidity also changes and may be selectively increased to provide tailored support for the individual user (or user).

[0158] In some forms of the present technology, the positioning and stabilising structure is bifurcated into a first section and a second section. The positioning and stabilising structure may be bifurcated at opposed ends thereof, or at a position adjacent to a temporal region of a user's head in use. The first and second bifurcated sections may jointly cradle a crown of the user's head in use. The first section may be movable relative to the second section. Alternatively, the first section and the second section is bifurcated at a fixed angle. The angle may be about 60° to about 120°.

[0159] When the positioning and stabilising structure is formed as a headband, the positioning and stabilising structure may be fabric material or composite material. The positioning and stabilising structure may be made breathable, so as to provide comfort to the user.

[0160] In one form of the present technology, the positioning and stabilising structure is configured to loop over the user's ears. The positioning and stabilising structure may have a curved morphology, such that it arcs over the otobasion superior region of the user's head and a lower occipital region. The positioning and stabilising structure may comprise a rigidiser to maintain the arc.

[0161] The positioning and stabilising structure may be formed from a material selected from perforated textile, breathable foam and / or fiber. Alternatively, a fabric composite material may be used. The composite material may be a laminated material.

[0162] In one form of the present technology, the positioning and stabilising structure is an elastic fabric material. For example, polyester, cotton, spandex, or nylon may be used, which may be further laminated with another fabric.

[0163] Materials

[0164] Various materials may be used to provide a soft touch feel and comfort to the user. Together, a unitary one-piece structure is formed, comprising a number of different textile structures used alternatively or in combination (e.g., a knit structure, a woven structure, different types of knit structures, different types of woven structures). The textile structures may vary across various sections and / or areas of the eye mask. The various textile structures may impart the eye mask with variations in physical properties or characteristics - e.g., cushioning ability, thickness, stretch, stretch-resistance, directional stretch, certain elongation ranges, elasticity, elastic recovery, rigidity, stiffness, porosity, breathability, stability, layering - across the sections and / or areas of the eye mask. That is, the eye mask (or portions thereof) may have a composite textile structure (i.e., a textile formation pattern across the eye mask (or portions thereof)) that includes different textile structures.

[0165] Additionally, textile composition (e.g., material composition, yarn count) may vary across the eye mask to customize physical properties and / or characteristics of the eye mask, e.g., stretch, rigidity, stiffness, elasticity, elastic recovery, porosity, cushioning level, thickness, weight, and / or bulk, etc.

[0166] For example, elastomeric nonwoven may provide soft, airtight surface which may be incorporated as a material for forming the positioning and stabilising structure. The elastomeric nonwoven may further be used as a cushion material on the positioning and stabilising structure. Further, the elastomeric nonwoven may be bonded to a variety of materials which is commonly used for the user interface. Elastomeric nonwoven provides better elastic recovery to the positioning and stabilising structure, thus providing lower deformation and longer usage. The nonwoven material is soft and flexible. The material is soft in the sense that it may give way under pressure. The material is flexible in the sense that it is capable of being flexed or bent without breaking. The nonwoven material may be formed as a layer on a user-facing side, which is an outside surface which may be in contact with the user's skin when in use. The nonwoven material may be used as is without any additional support provided by adding other more resilient materials, or may be configured to provide sufficient structural support for it to be used alone. Alternatively, the nonwoven material may be bonded to a flexible and / or resilient material for further structural support.

[0167] Elastomeric nonwoven refers to an elastomer which is formed as a fabric-like material. An elastomer is a polymer that displays rubber-like elasticity. It has both viscosity and elasticity properties, weak intermolecular forces and low Young's modulus. A nonwoven fabric is a fabric-like material made from staple fiber (short) and long fibers (continuous long), bonded together by entangling fibers via chemical, mechanical or solvent treatment. Nonwoven fabric is not woven nor knitted.

[0168] The elastomeric polymer comprises hard segments and soft segments. The hard segments provide strength and rigidity while the soft segments provide elasticity but may result in a tackiness of the fabric. A balance of hard and soft segments is required to maximise the desirable properties of both the hard and soft segments.

[0169] The elastomeric nonwoven may be melt-blown. Melt-blown nonwovens are produced by extruding melted polymer fibers through a spin net or die consisting of up to 40 holes per inch to form long thin fibers which are stretched and cooled by passing hot air over the fibers as they fall from the die. The resultant web is collected and formed as a fabriclike material. The fibers from a melt-blown process may be made extremely fine. The melt-blown fibers may also be combined with other types of elastomeric nonwoven such as staple, spunbond and / or flashspun to form a fabric-like material with different properties.

[0170] In one form of the present technology, the elastomeric nonwoven layer is formed from a thermoplastic elastomer. In one form of the present technology, the elastomeric nonwoven layer is selected from polyolefin based elastomer, co-polyester elastomer, thermoplastic polyurethane elastomer, styrenic block copolymer, or a combination thereof. The elastomeric nonwoven layer may have hard:soft segment ratio of 1 :0.1 to about 1 : 10.

[0171] In one form of the present technology, the elastomeric nonwoven is selected from polyether block amide (Pebax), thermoplastic elastomer ether ester (Hytrel), thermoplastic polyurethane (Elastolan), styrenic rubber block co-polymer (Kraton), or a combination thereof. In one form of the present technology, the elastomeric nonwoven is selected from polyether block amide (Pebax), thermoplastic elastomer ether ester (Hytrel), or a combination thereof. For example, Pebax comprises nylon 11 as the hard segment while Hytrel comprises polybutylene terephthalate as the hard segment.

[0172] In one form of the present technology, the nonwoven is calendered. Calendering of fabric is a finishing process used to smooth, coat, or thin a material. The fabric is passed between rollers at high temperature and pressures. This process flattens circular fibers on the surface and decrease inter-fiber distance and pore size of the fabric. This polishes the surface of the fabric and makes the fabric smoother and more lustrous.

[0173] In one form of the present technology, the nonwoven is bonded to the flexible and / or resilient material. The flexible and / or resilient material may be a foam. The flexible and / or resilient material may be selected from silicone, polycarbonate, polyethylene, polypropylene, polystyrene, polyurethane, nylon, thermoplastic elastomer, polycarbonate-acrylonitrile butadiene sytene (PC-ABS), polyethylene terephthalate (PET), or a combination thereof. The strength of the bond may be measured using ASTM S1876-08. In one form of the present technology, the nonwoven is ultrasonically bonded to the flexible material. Alternatively, the nonwoven may be bonded to the flexible material via adhesive, lamination, thermal sealing, mechanical bonding, chemical bonding and / or welding.

[0174] Other types of fabric may also be used. For example, a knit fabric may be used, such as a cotton knit. A woven fabric may also be used. The difference between woven fabric and knit fabric is the yarn that they are composed of. Knit fabric is made of a single yarn, looped continuously to provide a braided pattern. Based on the inter looping direction, knitted fabrics may be classified as warp knitted fabric or weft knitted fabric. Knit fabric stretches easily along its width with a slightly less stretch along its length. A woven fabric is composed of multiple yarns wound at right angles to one another such that they create a criss-cross pattern. Woven fabric stretches along its length, but is less stretchable along its width. Thus, in general, knitted fabric are more flexible than woven fabric.

[0175] The knitted fabric or woven fabric may be made from a yarn selected from natural and / or synthetic fibers. Examples of such fibers include, but is not limited to, cotton, wool, enset, jute, viscose, polyester, and spandex.

[0176] In one form of the present technology, the knitted fabric is a weft knitted fabric. In one form of the present technology, the knitted fabric is a warp knitted fabric.

[0177] The fabrics may be combined using techniques such as lamination, adhesive, thermal sealing, mechanical bonding, chemical bonding and / or welding.

[0178] In one form of the present technology, at least two fabrics are connected together. The fabrics may be continuously joined to each other. In this regard, one fabric transit seamlessly to another. Alternatively, the fabrics may be connected together via a seam, stitch and / or adhesive. This allows different types of fabric to be used to form the body, to achieve a variety of functionalities.

[0179] In one form of the present technology, the eye mask is formed from a spacer fabric. Spacer fabric contains a combination of two independent textile sheets interconnected with spacer yarns (forming a spacer layer) so that the fabric has a 3D appearance. The spacer fabric may comprise two knitted fabrics separated by spacer yarns. Because of the spacer yarns, a defined distance may be established between the textile sheets. The textile sheets may be constructed similarly or differently to achieve a multitude of functionalities. The spacer layer may comprise monofilaments and / or multifilaments. Monofilament refers to a single solid filament. Multifilament refers to a yarn which has multiple filament fibers twisted together. While spacer fabric having monofilaments may be stiffer, can resist high pressure and may allow for directed transport of fluid and heat, spacer fabric having multifilaments allows for more movement and flexibility. Accordingly, a combination of monofilaments and multifilaments may be used. The filaments may be formed from a material selected from polyester, nylon and / or recycled yarn. Other materials include, but is not limited to, cotton, viscose, rayon, acrylic, elastane, blended yarn comprising polyester and cotton / viscose, cotton / acrylic, polyacrylic in different proportions or combinations.

[0180] In one form of the present technology, the spacer fabric is characterised by a thickness of about 2 mm to about 10 mm.

[0181] Other types of fabric may be used, such as flat, warp, large and small-drum circular knitting, spacer mesh, and quilt with filler. Any material use to fabricate fabric may be used. For example, the material may be selected from virgin and / or recycled polyester, polypropylene, polyamide, various spandex or stretch materials, poly(lactic acid), wool, cotton, bamboo, jute, or a combination thereof. In one form of the present technology, the material is an elastic material.

[0182] In addition to fabric materials, other materials such as fabric fiberfill (for example, polyester fiberfill), non-woven padding, foam padding, high density upholstery foam, compressed polyester, medium density polyurethane antimicrobial foam, high density polyurethane foam, dry fast open cell foam, or a combination thereof may also be used to provide support and comfort to the user.

[0183] Some exemplary embodiments of the present technology are described below.

[0184] FIG. 1A shows an eye mask 1000. The eye mask 1000 comprises an eye component 1010 positioned over at least orbital regions of a face of a user. The orbital region includes a supra-orbital region. The eye component 1010 is further positioned over a portion of an infra-orbital region of the user. The eye component 1010 is configured to block light to the eyes. The eye component 1010 is further positioned over a portion of a nasal region of the user. The eye component 1010 is further positioned over a portion of a zygomatic region of the user. The eye mask 1000 comprises a face-contacting structure 1020 connected to the eye component 1010. The face-contacting structure 1020 is constructed and arranged to engage the user's face. This prevents stray light from entering the inner space of the eye mask 1000 and to the eyes. A positioning and stabilising structure 1030 is attached to the eye component 1010 for attaching the eye mask 1000 to the user's face. The positioning and stabilising structure 1030 may be laminated to the eye component 1010. The positioning and stabilising structure 1030 may be formed as an elastic headband and comprises a front section 1030A and a rear section 1030B. This may provide additional support to prevent displacement of the eye mask 1000 during use.

[0185] FIG. IB shows the user facing side of eye mask 1000. The eye component 1010 comprises at least one cavity configured to space the eye component apart from the eyes of the user. The cavity over each eye of the user is linked via a bridge portion. The face-contacting structure 1020 further comprises a bridge 1040 for stabilising the eye mask 1000 on a nasal region of the user's face. The bridge 1040 may be made of a different material (for example, a stiffer material) than the face-contacting structure 1020.

[0186] FIG. 2A illustrates another eye mask 2000. Eye mask 2000 comprises an eye component 2010. The face-contacting structure 2020 underlies the eye component 2010. The positioning and stabilising structure 2030 is attached to the eye component 1010. The positioning and stabilising structure 2030 formed as a flexible headband circumferentially positionable on a user's head. The positioning and stabilising structure 2030 may further be contiguous with the eye component 2010 such that the eye mask may be worn as a headband on a user's head when not in use. Eye component 2010 is circumferentially attached to at least a portion of the positioning and stabilising structure 2030. Alternatively, eye component 2010 may be formed as a flexible headband circumferentially attached to the positioning and stabilising structure 2030. In this position, the eye component 2010 overlays the positioning and stabilising structure 2030. The positioning and stabilising structure 2030 and the eye component 2010 may be formed of different materials. Alternatively, the face-contacting structure 2020 may be formed of a different material relative to the eye component 2010.

[0187] In use, the eye component 2010 may be pulled down to cover the user's eyes (FIG. 2B). The face-contacting structure 2020 contacts at least the orbital regions of the user's face to block out light to the eyes. Pulling down the eye component 2010 exposes a sensor module 2050 positioned on the positioning and stabilising structure 2030. The sensor module 2050 may be detachable, and may be configured to measure EEG.

[0188] Eye mask 3000 is shown in FIG. 3A. Eye mask 3000 comprises an eye component 3010 and face-contacting structure 3020. The eye component 3010 may be a perforated, light blocking material or composite material. The eye component 3010 may be made breathable, so as to provide comfort to the user. The face-contacting structure 3020 may be a breathable foam. The eye component 3010 may be laminated to the facecontacting structure 3020. The eye component 3010 is attached to a positioning and stabilising structure 3030 at its ends thereof. The positioning and stabilising structure 3030 may be a strap, which may be elastic. The positioning and stabilising structure 3030 may further comprise adjustable means for fitting the eye mask 3000 to the user's head.

[0189] FIG. 3B shows the user facing side of the eye component 3010 and face-contacting structure 3020 of eye mask 3000. The eye component (and the face-contacting structure 3020) is further positionable over the forehead of the user. Eye component 3010 may be a perforated, light blocking material or composite material laminated to face-contacting structure 3020. The face-contacting structure 3020 comprises at least one orifice for housing the eye component 3010. The face-contacting structure 3020 comprises a foam, having a thickness of about 1 cm to about 10 cm. The face-contacting structure 3020 may have a gradient of decreasing thickness towards the orifice in order to improve the breathability of the eye mask 3000. The face-contacting structure 3020 may further be perforated to increase the breathability of the eye mask 3000.

[0190] Eye mask 400 of FIG. 4A comprises an eye component 4010, face-contacting structure 4020 and positioning and stabilising structure. As shown in FIG. 4B, the positioning and stabilising structure may be bifurcated into a first section 4070A and a second section 4070B. The positioning and stabilising structure may be bifurcated at opposed sides of the eye component 4010, or adjacent to a temporal region of a user's head in use. The eye mask 4000 comprises a noise reduction component 4060 configured to fit over and / or at least partially inside respective ears of the user. The noise reduction component 4060 may be coupled to the eye component 4010. The noise reduction component 4060 may be contiguous with the eye component 4010. In this regard, the noise reduction component 4060 and the eye component 4010 may be formed form a single material or composite material. Alternatively, the noise reduction component 4060 may be a modular component which is attachable to the eye mask 4000 via tabs at opposed ends of the eye component 4010 thereof.

[0191] FIG. 4C shows the components of a noise reduction component 4060. The noise reduction component 4060 comprises a sound absorbing material 4210, a sound absorbing foam 4220, a speaker casing 4230, a speaker 4240, a second sound absorbing foam 4250, and a mesh material 4260. The sound absorbing material 4210, a second sound absorbing foam 4250, and a mesh material 4260 may be laminated together, and provides with passive sound blocking. The speaker 4240 may provide white noise to aid a user's sleep. A noise cancelling component may also be incorporated, and may provide Al-assisted smart sound blocking or active noisecancellation electronics while ensuring essential sounds such as a baby's cry can still pass through.

[0192] FIG. 5A is a further embodiment of the eye mask 5000. The eye component 5010 and face-contacting structure 5020 are similarly sized and covers the forehead and a portion of the nasal region of the user's face. The positioning and stabilising structure 5030 has a similar width relative to the eye component 5010, and overlays at least an otobasion superior region of the user's head in use. The positioning and stabilising component 5030 may be configured to overlay an otobasion superior region and otobasion inferior region of the user's head in use.

[0193] FIG. 5B shows the eye mask 5000 in a scrunched up configuration. The positioning and stabilising structure 5030 may be pretensioned and made from a soft elastic textile to evenly distribute contact pressure on the face. The curved morphology of the eye component 5010 conforms to the user's face, and provides better skin contact and light blocking.

The eye component 6010 and face-contacting structure 6020 are similarly sized and covers the forehead and a portion of the nasal region of the user's face. The face-contacting structure 6020 is further contoured to conform to the user's face for a better fit. In this regard, the eye mask 6000 further comprises a bridge portion 6040 between the left and right orbital regions of the eye component 6010. This may provide better stability to the eye mask 6000 when in use. The positioning and stabilising structure 6030 overlays an otobasion superior region of the user's head in use. The positioning and stabilising structure 6030 comprises a rigidiser 6080. The rigidiser 6080 may extend throughout the positioning and stabilising structure 6030 or at least at a portion of the positioning and stabilising structure 6030. The rigidiser 6030 provides stability to the eye mask 6000 during use.

[0195] FIG. 7A shows an eye mask 7000. The eye component 7010 and face-contacting structure 7020 are similarly sized and covers the forehead and a portion of the nasal region of the user's face. The face-contacting structure 7020 is further contoured to conform to the user's face for a better fit. In this regard, the eye mask 7000 further comprises a bridge portion 7040 between the left and right orbital regions of the eye component 7010. This may provide better stability to the eye mask 7000 when in use. The positioning and stabilising structure 7030 overlays a otobasion superior region of the user's head in use. The positioning and stabilising structure 7030 may comprise adjustable means for tightening the eye mask 7000 to a user's head.

[0196] FIG. 7B and 7C show the positioning and stabilising structure 7030 bifurcated at opposed sides of the eye component 7010, or adjacent to a temporal region of a user's head in use. The positioning and stabilising structure 7030 is bifurcated to form a first bifurcated section 7070A and a second bifurcated section 7070B, wherein the first and second bifurcated sections jointly cradle a crown of the user's head in use. The first bifurcated section 7070A and second bifurcated section 7070B may be movable relative to each other such that the user may adjust the positioning and stabilising structure 7030 to a comfortable position.

[0197] FIG. 8A shows an eye mask 8000. The eye component 8010 and face-contacting structure 8020 are similarly sized and covers the forehead and a portion of the nasal region of the user's face. The face-contacting structure 8020 is further contoured to conform to the user's face for a better fit. In this regard, the eye mask 8000 further comprises a bridge portion 8040 between the left and right orbital regions of the eye component 8010. This may provide better stability to the eye mask 8000 when in use. The positioning and stabilising structure 8030 overlays an otobasion superior region of the user's head in use. The positioning and stabilising structure 8030 may comprise adjustable means for tightening the eye mask 7000 to a user's head.

[0198] FIG. 8B shows the positioning and stabilising structure 8030 bifurcated at opposed sides of the eye component 8010, or adjacent to a temporal region of a user's head in use. The positioning and stabilising structure 8030 is bifurcated to form a first bifurcated section 8070A and a second bifurcated section 8070B, wherein the first and second bifurcated sections jointly cradle a crown of the user's head in use. In this case, the angle at which the first bifurcated section 8070A and second bifurcated section 8070B meets with each other is fixed, and may be about 60° to about 120°. The positioning and stabilising structure 8030 may have a width or thickness of about 10 mm to about 50 mm, and may be formed from a fabric composite material. The positioning and stabilising structure 8030 may comprise a foam sandwiched between fabric layers.

[0199] FIG. 9A and 9B show an eye mask 9000. The eye component 9010 and face-contacting structure 9020 are similarly sized. The face-contacting structure 9020 is further contoured to conform to the user's face for a better fit. The eye mask 9000 further comprises a bridge portion 9040 between the left and right orbital regions of the eye component 9010. The positioning and stabilising structure comprises a first section 9072 which acts as a headband, configured to circumferentially and elastically bind to the user's head. A second section 9074 is connected to the eye component 9010 and is movably attached to the first section 9072. The eye mask 9000 further comprises flip means 9080 for movably connecting the eye component to the positioning and stabilising structure between an open position and a closed position. The flip means 9080 may be positioned adjacent to the forehead of the user. In the open position, the eye component 9010 is positioned away from the user's eyes. For example, the eye component 9010 may be held adjacent to the forehead of the user (FIG. 9A). In the closed position, the eye mask 9000 is moved downwards to cover the forehead, orbital regions and a portion of the nasal region of the user's face (FIG. 9B). The facecontacting structure 9020 is made to contact the user's face.

[0200] FIG. 9C shows eye mask 9000. The flip means 9080 may be a spring such as a leaf spring. This provides a tactile feedback and springs to the open or closed position automatically.

[0201] FIG. 10A shows eye mask 10000. The eye mask 10000 may rest on a user's forehead when the user is not yet ready for sleep. The eye mask 10000 comprises an eye component 10010, a face-contacting structure and positioning and stabilising structure. The face-contacting structure is dimensioned to be similar in size with the eye component 10010. The eye component 10010 and face-contacting structure may be formed from a single material or composite material. The face-contacting structure may further comprise thermoformed bridge portion to conform to the nose and further aid in light blocking. The eye component 10010 forms an outer band which loops around the user's head. The eye component 10010 is connected to the positioning and stabilising structure, for example, via a textile shroud. For example, the positioning and stabilising structure may form an inner band within loops around the user's head. The inner band may be circumferentially connected to the outer band. In this position, the positioning and stabilising structure is hidden behind the eye component 10010. The eye component 10010 is movably to cover at least the eyes of the user

[0202] Textile Structures and Composition

[0203] Described below are various examples of strap portions suitable for use in headgear of or forming a positioning and stabilising structure according to examples of the present technology. Various examples of strap constructions and compositions are disclosed below, each of which is to be understood to be applicable to any portion of any of the positioning and stabilising structures or eye masks described with reference to Figs. 1A- 10B.

[0204] In accordance with examples of this disclosure, headgear (e.g., a headgear strap) may be formed with physical properties and / or characteristics that vary across the headgear and / or portions thereof. The entire headgear or portions of the headgear may be formed as a single piece of textile material directly into its final shape. In examples, the variations in physical properties and / or characteristics may be provided by different textile structures, textile composition and / or combinations thereof.

[0205] The headgear may be formed by knitting (e.g., flat knitting or circular knitting, however other forms of knitting may also be possible) and / or weaving. In accordance with examples of the disclosed technology, headgear may be formed using narrow elastic technology on a jacquard Raschel machine or Santoni machine (Jacquardtronic 3D knitting). Additionally, a double needle bar machine for 4D knitted fabrics, spacer fabrics and double layer fabrics may be used. Headgear may be formed with a unitary, seamless structure.

[0206] In examples, the headgear may be formed primarily from multiple yarns that are mechanically manipulated either through an interlooping process (e.g., knitting) or a weaving process to produce a single unitary structure having various sections with different physical properties. Monofilaments and multifilament yarns may be used.

[0207] A measure of stretchability may be referred to by an amount of force required to elongate a material by a certain length; thus, a first material having increased stretchability (as compared to a second material) may require less force to elongate the material a certain length as compared to the second material. Rigidity may refer to the relative stiffness of the textile or headgear in relation to bending in and out of planes (e.g., the planes extending in the lengthwise direction and height direction (also referred to as width) of the headgear). A textile with higher rigidity will have relatively increased resistance (less compliancy) to bending out of plane. An increase in rigidity may also result in reduced stretchability. It is also noted that the inverse of stiffness is flexibility.

[0208] In examples, the headgear may be formed as a unitary one-piece structure comprising a number of different textile structures used alternatively or in combination (e.g., a knit structure, a woven structure, different types of knit structures, different types of woven structures). The textile structures may vary across various sections and / or areas of the headgear. The various textile structures may impart the headgear with variations in physical properties or characteristics - e.g., cushioning ability, thickness, stretch, stretch-resistance, directional stretch, certain elongation ranges, elasticity, elastic recovery, rigidity, stiffness, porosity, breathability, stability, layering - across the sections and / or areas of the headgear. That is, the headgear (or portions thereof) may have a composite textile structure (i.e., a textile formation pattern across the headgear (or portions thereof)) that includes different textile structures.

[0209] Additionally, textile composition (e.g., material composition, yarn count) may vary across the headgear to customize physical properties and / or characteristics of the headgear, e.g., stretch, rigidity, stiffness, elasticity, elastic recovery, porosity, cushioning level, thickness, weight, and / or bulk, etc.

[0210] The headgear may be comprised of one or more suitable materials (e.g., fibers or filaments of nylon, polyester, cotton, recycled polyester, recycled nylon, and any blend thereof, such as polyester and cotton blend, and nylon and polyester blend. Any of these materials may be mixed with a stretch fiber (e.g., nylon and stretch fiber mix)). The stretch fiber could be, for example, elastane or spandex. A material such as nylon may be provided over a stretch fiber core (e.g., elastane) to provide a nylon / elastane mix fiber. The material composition of the headgear may vary across the headgear in order to alter physical properties and / or characteristics (e.g., stretch, rigidity, elastic recovery, etc.) of the headgear in different portions, sections and / or areas of the headgear. For example, the ratio of different yarn materials may be different in different portions of the headgear in order to vary stretch and / or rigidity (or other properties). In an example, the ratio of stretch fiber (e.g., elastane) in the yarns may vary from one portion of the headgear to another portion, such that areas with a higher elastane ratio may have increased stretchability. For example, some yarns may not comprise any stretch fibers, whereas other yarns may comprise a stretch fiber with a single-layer covering of another material (e.g., nylon) or a double-layer covering of another material (e.g., nylon) to adjust stretchability as desired.

[0211] Further, in some examples, the yarn count (i.e., denier (D) or liner density of the yarn) may vary across the headgear in order to alter physical properties and / or characteristics (e.g., cushioning level, thickness, stretch, rigidity, elastic recovery, porosity, etc.) of the headgear in different portions, sections and / or areas of the headgear. In an example, an area of the headgear having yarn(s) with relatively high denier may be thicker, have increased rigidity and / or reduced stretchability. Thus, portions of the headgear having yarn(s) with relatively lower denier may be thinner, have a smoother surface texture, have increased elasticity and have increased elastic recovery. Also, in some examples multiple yarns (e.g., 2, 3 or 4 yarns) having different denier may be used in the same area of the headgear to tailor physical properties as desired. However, as noted above, the textile structure and material composition will also influence the physical properties and characteristics of the headgear.

[0212] Additionally, in some examples, the headgear may include one or more rigidizers that are structured to add rigidity, stiffness, form and / or stability to the headgear. For example, the headgear may be formed with a thermosetting, thermo-fusible, or thermo- bondable yarn or thread, e.g., made from polymers such as co-polyamides, copolyester, and polyolefins. That is, the rigidizing yarn may have a lower melt temperature (e.g., in the range of 80° to 160°) than other yarns. The headgear may be placed in a frame to hold the headgear in place, and then the headgear may be heated and cooled to heat-form, rigidize and set the rigidizing yarn.

[0213] The percentage of rigidizing yarn (i.e., percentage of the yarn in a particular area that is rigidizing yarn vs. non-rigidizing yarn) may vary across the headgear, such that a first area of the headgear may have a higher or lower percentage of rigidizing yarn as compared to a second area of the headgear. In this way, the level of rigidity (and / or stretchability) may be controlled in different areas of the headgear. That is, areas with a relatively higher percentage of rigidizing yarn may achieve a higher level of rigidity (and reduced stretchability) once heated and cooled during the rigidizing process (it is noted that the rigidizing yarn will tend to reduce stretchability of the headgear, e.g., in some examples maintaining some stretchabilty and in other examples eliminating stretchability such that the headgear portion is non-stretchable). It is further noted that multiple areas (2, 3, 4, 5, 6, 7 or more areas) of the headgear may have different percentages of the rigidizing yarn to tailor the rigidity and / or stretchability of the headgear as desired.

[0214] Additionally, the percentage of rigidizing yarn may be varied across the headgear, in addition to variations in the textile structure, material composition, and yarn count, as described above, to achieve desired properties and / or characteristics in certain areas of the headgear.

[0215] Thus, the textile composition may be varied across the headgear, in addition to variations in the textile structure as described above, to achieve desired properties and / or characteristics in certain areas of the headgear.

[0216] In one form of the present technology, the material comprises a ribbed textile structure. For example, the positioning and stabilising structure may comprise a ribbed textile structure. The positioning and stabilising structure may have a slit that bifurcates into a superior strap portion and an inferior strap portion. The slit may be at a central portion of the positioning and stabilising structure. Either of the superior strap portion and the inferior strap portion may have a ribbed textile structure. In a further example, the ribbed textile structure is a hollow ribbed textile structure. The ribbed textile structure may have repeating rows of protrusions formed as hollow portions and may be configured to provide the user with enhanced cushioning (e.g. greater compliance) in use.

[0217] Turning to Fig. 11A, a schematic representation of a ribbed textile structure 3390 is shown. The ribbed textile structure is in a stretched or extended state due to a force (e.g. tension) being applied to the textile. The ribbed textile structure 3390 may provide a high degree of stretchability that is attributable to the textile structure rather than the yarn type (e.g., relatively high stretchability is achievable without use of elastane if desired). The ribbed textile structure 3390 may have increased stretchability as compared to other textile structures (e.g., jersey knit structure, honeycomb knit structure, mesh knit structure, pique knit structure, interlock knit structure, and plain weave, etc.). As is described in detail elsewhere herein, an orientation of the rib structure can be adjusted (e.g., vertical orientation, horizontal orientation) to orient the primary stretch direction as desired (e.g., along the length of the headgear or along a width (or height) of the headgear). However, when the textile is relaxed and under no strain, the textile tends to contract, as shown in Fig. 11B. Since the ribbed textile structure tends to naturally contract when no force is applied, the ribbed textile structure may have excellent elastic recovery / rebound (e.g., increased elastic recovery as compared to other knit structures (e.g., jersey knit structure, honeycomb knit structure, mesh knit structure, pique knit structure, interlock knit structure, and plain weave, etc.)). This is also advantageous since the headgear may have a smaller profile when not in use thereby making it easier to store or travel with the headgear.

[0218] In examples, the ribbed textile structure 3390 may include a monofilament. In some examples, the monofilament may be constructed (e.g., of relatively rigid material) to reduce stretchability (increase rigidity), and in other examples, the monofilament may be constructed (e.g., of relatively elastic material) to increase stretchability / elastic properties.

[0219] Referring to Fig. 12A-1, a cross-sectional view of a ribbed textile structure 3390 according to an example of the present technology is shown. The ribbed textile structure 3390 may be a rib knit structure (e.g., 1x1, 2x2, 2x1, etc. rib knit) or a ribbed woven structure (e.g., ribbed weave), for example. The ribbed textile structure 3390 may have protrusions 3392 and recesses 3394 on both the technical back and the technical face. For example, the technical back of the textile structure may be a user-contacting layer, and the technical face of the textile may be a layer which is outwardly facing with respect to the user in use.

[0220] In another example, the ribbed textile structure 3390 may be a spacer fabric with rib structure (e.g., a ribbed spacer fabric 3380 where the inner layer 3382 and the outer layer 3384 of the spacer fabric have a rib knit structure and are connected by an inner layer of (spacer) pile threads 3386), as shown in Fig. 12A-2. The thickness of the ribbed spacer fabric 3380 may be adjusted by altering the length of the pile threads 3386. In some examples, the spacer fabric 3380 may have increased cushioning as compared to some other textile structures (e.g., single knits). Further, the thickness of the ribbed spacer fabric 3380 vary across the headgear providing thicker more cushioned areas along desired portions of the headgear. Thus, the ribbed spacer fabric 3380 may provide a combination of increased stretchability and increased cushioning as compared to other textile structures.

[0221] Figs. 12B-1 and 12B-2 show a ribbed textile structure 3390 that has repeating rows of protrusions formed as hollow portions. This textile structure may be referred to as a hollow ribbed textile structure 3393, e.g., a hollow rib knit or a hollow rib weave (these textile structures may also be referred to as tubular rib knit and tubular rib weave, respectively). The hollow ribbed textile structure 3393 has a technical face and technical back formed by alternating rows of hollow portions 3395 and recessed portions 3397. As shown in Fig. 12B-1, the hollow portions 3395 may be formed as tubular shaped textile formations with a hollow interior. As can be seen in Fig. 12B-2, the hollow portions 3395 create protrusions on both sides of the textile, whereas the recessed portions 3397 form recesses between adjacent hollow portions. Superior and inferior edges of the hollow ribbed textile structure 3393 may be capped with piping 3398 such that the hollow interior portions are not exposed.

[0222] The protrusions formed by the hollow portions 3395 may provide the hollow ribbed textile structure with an increased thickness d, as compared to other textile structures (e.g., jersey knit structure, honeycomb knit structure, mesh knit structure, pique knit structure, interlock knit structure, and plain weave, etc.). Even as compared to ribbed structures without hollow portions, such as the ribbed textile structure 3390 shown in Fig. 12A-1, a height of the hollow portions 3395 from a central plane 3396 will typically be greater than a height of the protrusions 3392 from a similar plane. Thus, the increased thickness d and the empty interior space created by the hollow portions 3395 may allow the hollow ribbed textile structure 3393 to compress a further distance (i.e., as compared to the other textile structures) in the thickness direction of the headgear in response to headgear tension, which may reduce pressure points and enhance comfort. In this way, the hollow ribbed textile structure 3393 may provide greater compliance (e.g. providing enhanced cushioning to the user), as compared to the other textile structures. Additionally, the recessed portions 3397 may allow airflow in an area between the headgear and user's head which may enhance breathability, cooling and overall comfort.

[0223] It is also noted that a first section or portion of the headgear may have a different textile structure than other sections / portions (e.g., second, third, etc. sections or portions of the headgear). For example, a knit structure and a woven structure can be considered different textile structures. Also, a ribbed structure (e.g., rib knit or ribbed weave) and a non-ribbed structure (e.g., jersey knit structure, mesh knit structure, pique knit structure, interlock knit structure, and plain weave) can be considered different textile structures. Similarly, different types of textile structures, such as knit and interlock, or mesh and pique, can also be considered different textile structures. In addition to different types of textile structures, a rib knit having, e.g., a 1x1 construction, can also be considered a different textile structure than a rib knit having a different construction (e.g., a 2x1 construction).

[0224] Additional Illustrated examples of Headgear and Headgear Straps

[0225] In the illustrated examples that follow, the headgear or headgear strap may include a ribbed textile structure 3390. It is noted that the ribbed textile structure 3390 could, for example, be a rib knit structure (e.g., 1x1, 2x2, 2x1), a ribbed woven structure, a ribbed spacer fabric 3380, or a hollow ribbed textile structure 3393 (e.g., a hollow rib knit or a hollow rib weave), having properties and features as described elsewhere herein. Features described with respect to one illustrated example may be applicable to other examples. For the sake of brevity, the discussion of a particular illustrated example may only describe differences in that illustrated example as compared to other examples. For illustrated examples where the side portions 3312 are not depicted, it is to be understood that the side portions may be the same as described with respect to Fig. 13, or may have a different construction, shape or configuration. Additionally, although the side portions 3312 may be connected to the central portion 3314 with a seam, the entire headgear strap 3315 (or portions thereof) may be formed in one-piece directly into its final shape in other examples. It is to be understood that any ribbed textile structure 3390 described herein may be provided to any portion of any headgear strap or portion of a positioning and stabilising structure 3300 described herein.

[0226] Referring to Fig. 13, the central portion 3314 of headgear strap 3315 has a bifurcated construction. A headgear strap 3315 with this bifurcated construction may be configured to engage a posterior portion of the user's head in use and may include a superior strap portion 3316 and an inferior strap portion 3318, wherein the superior strap portion 3316 is configured to sit higher, or in a more superior position on the user's head than the inferior strap portion 3318. In other examples, the headgear strap 3315 may not be bifurcated and the superior strap portion 3316 and inferior strap portion 3318 may be adjacent to each other with separation / spacing between them. Such a non-bifurcated strap 3315 may be configured to engage any of a posterior, superior or anterior portion of the user's head in use. In the Fig. 13 example, the central portion 3314 includes a ribbed textile structure 3390 in a vertical orientation extending over both the superior strap portion 3316 and the inferior strap portion 3318 which are separated by slit 3313 to create multi-level stretch across the central section 3317 which, advantageously, may facilitate stretch across differently shaped portions of the user's head. Due to the vertical orientation, the ribbed textile structure may have greater stretchability in the length direction of the headgear strap as compared to stretchability in the width direction of the headgear strap. This may allow the headgear strap to comfortably accommodate a range of head sizes by stretching comfortably around the central portion of the user's head. This arrangement also provides the headgear strap with good bending stiffness such that the headgear strap comfortably accommodates curvature of the user's head without succumbing to excessive deformation. While reference is made to "vertical" in the above paragraph describing Fig. 13, in an example in which the strap 3315 engages a superior portion of the user's head, the ribs of the ribbed textile structure 3390 may extend in anterior-posterior directions in use. In examples in which the strap 3315 engages an anterior portion of the user's head, e.g. overlying the frontal bone (e.g. on the forehead), the ribs of the ribbed textile structure 3390 may extend partially horizontally and partially vertically.

[0227] In other examples, the ribbed textile structure 3390 may include Jacquard sophisticated geometry, Jacquard Scotweave graphic, diamond weave, and / or basic weave structure (e.g., double-warp technique (2 warps, 1 weft) or triple warp technique (3 warps, 1 weft). These textile structures may be configured to create 3-dimensional technical effects that may form a raised profile that enhances cushioning (e.g. greater compliance and / or perceived softness).

[0228] In other examples, the ribbed textile structure 3390 may include tubular cord, open- worked twill weave in the weft direction, regular zig-zags in the warp direction, uniform ridge twill, balanced twills, and / or multiple-ridge twills.

[0229] In the illustrated example of Fig. 13, the entire central portion 3314 has the same textile structure. In other examples, the textile structure may vary across the central portion. For example, the lateral sections 3319 may have a different textile structure than the central section 3317. In other examples, the superior strap portion 3316 may have a different textile structure than the inferior strap portion 3318.

[0230] The side portions 3312 may be configured to have less stretch and less cushioning as compared to the central portion 3314, e.g., due to different textile structures and / or different textile composition. In examples, the side portions 3312 may have a textile structure that includes pique, mesh, interlock, honeycomb, and / or plain jersey. In other examples, some section(s) of the side portions 3312 may have a textile structure that includes pique, mesh, interlock, honeycomb, and / or plain jersey and other section(s) of the side portions 3312 may have a textile structure that includes rib knit or weave (e.g., plain weave, ribbed weave, hollow rib weave). Additionally, the side portions may include a rigidizer to impart rigidity to the side portions. In some examples, the rigidizer may be a thermo-fusible yarn.

[0231] In further examples, the side portions 3312 may form sleeves having hollow interior portions that receive rigidizers (e.g., relatively rigid elongate materials such as plastic (e.g., rigidizer arms)) to impart rigidity to the side portions. In such examples, the rigidizer arms may connect directly to the eye component.

[0232] Fig. 14A is a schematic representation of the central portion 3314 of another headgear strap 3315. Similar to the example in Fig. 13, the central portion 3314 includes a ribbed textile structure 3390 in a vertical orientation. However, in this example, the ribbed textile structure 3390 is provided to only the central section 3317 and not the lateral sections 3319. Thus, the stretch and cushioning in the superior strap portion 3316 and the inferior strap portion 3318 may be the same. The lateral sections 3319 may have a textile structure that is the same as the textile structure of the side portions 3312 as described above with regard to Fig. 13. Thus, the central section 3317 may be configured to have increased stretch and / or increased cushioning as compared to the lateral sections 3319. In examples, the central section 3317 may have warp elongation (i.e., lengthwise direction of headgear strap) in the range of 160%-200%, and the lateral sections 3319 may have warp elongation in the range of 110%-150%.

[0233] Fig. 14B is a schematic representation of the rear portion 3314 of the headgear strap 3315 according to another example. Similar to the example of Fig 14A, the rear portion 3314 includes a ribbed textile structure 3390 in a vertical orientation, although this depends on the orientation of the strap 3315 in use and, as described in relation to the other examples, this may alternatively be a ribbed textile structure 3390 in a horizontal orientation. In this example the slit 3313 comprises one or more monofilament or multifilament yarns, which may for example form a mesh structure 3321 having one or more open spaces between the yarns. The mesh structure 3321 may join the superior portion 3316 to the inferior portion 3318. The mesh structure may have open spaces of between 1mm2and 100mm2inclusive, such as approximately 25mm2. In some examples, the mesh structure may be an eyelet mesh, or a pique mesh. In some examples the open spaces may have a quadrilateral shape, such as being substantially square, rectangular, diamond (including diamond meshes and thickened diamond structures, tetragonal, octagonal, triangular, dodecagonal, circular or a rhombus shape. For example, the mesh may include a biaxial four-thread square, biaxial six-thread square or four-axial six thread square shape. In some examples the mesh structure may be substantially irregular, such as an irregular hexagonal shape.

[0234] The monofilament or multifilament yarns may be constructed of any suitable material including nylon, polyester, polypropylene, silk, acrylic and fluorocarbon materials. Depending on the strap requirements, the monofilament or multifilament yarns may be selected to provide desirable stretch or extensibility characteristics. For example, less extensible materials or thicker yarns may be used to limit the stretch or extensibility characteristics in certain regions of the headgear, or conversely, thinner more extensible material may be used to provide greater stretch or extensibility characteristics.

[0235] In the illustrated example the mesh structure 3321 comprises a series of overlapping yarns in provided at an angle with respect to the vertical or inferior-superior direction of the headgear strap 3315. For example, each of the yarns may be provided at between 60 degrees and -60 degrees inclusive with respect to the vertical or inferior-superior direction, such as approximately 45 degrees. It should be appreciated that the angle of the yarns may be structured to control or limit the extension of the central section 3317. For example, using monofilament or multifilament yarns in a substantially vertical orientation may be used to limit the separation of the superior strap portion 3316 from the inferior strap portion 3318, i.e, in the weft direction, while not limiting the extension in the lengthwise or warp direction. Conversely, using monofilament or multifilament yarns in a substantially horizontal orientation may be used to limit the extension in the lengthwise or warp direction, while not limiting the separation of the superior strap portion 3316 from the inferior strap portion 3318, i.e., in the weft direction. Accordingly, angles between vertical and horizontal, such as between 60 degrees and -60 degrees inclusive with respect to the vertical or inferior-superior direction, can be used to adjust the warp and weft elongation characteristics of the headgear strap 3315.

[0236] The use of a mesh structure 3321 may advantageously provide headgear straps 3315 which are more comfortable, flexible or breathable. In addition, the mesh structure 3321 may be used to control or limit the extensibility characteristics of any one or more of the straps described herein, for example while maintaining high compliance benefits of the ribbed textile structure 3390, although this should not be seen as limiting.

[0237] The mesh structure 3321 may be attached to the central 3317 and or lateral sections 3319 using any suitable methods such as stitching, using adhesives, heat sealing, or ultrasonically welding. In another example the mesh structure 3321 may be positioned between an inner, user contacting layer, and an outer non user contacting layer of the headgear strap 3315.

[0238] The ribbed textile structure 3390 may be provided to the superior strap portion 3316 of the rear portion 3314 of a headgear strap 3315. Referring to Fig. 15, the ribbed textile structure 3390 is provided only to the superior strap portion 3316. All other areas (e.g., inferior strap portion 3318 and lateral sections 3319) of the central portion 3314 may have a textile structure that is the same as the textile structure of the side portions 3312 as described above with regard to Fig. 13. Thus, the superior strap portion 3316 may have increased stretch and / or increased cushioning as compared to the other areas of the central portion 3314. In examples, the superior strap portion 3316 may have warp elongation in the range of 160%-200%, and the inferior strap portion 3318 and lateral sections 3319 may have warp elongation in the range of 110%-150%.

[0239] The ribbed textile structure 3390 may be provided to the inferior strap portion 3318 of the rear portion 3314 of a headgear strap 3315. Referring to Fig. 16, the ribbed textile structure 3390 extends only along the inferior strap portion 3318. All other areas (e.g., superior strap portion 3316 and lateral sections 3319) of the central portion 3314 may have a textile structure that is the same as the textile structure of the side portions 3312 as described above with regard to Fig. 13. Thus, the inferior strap portion 3318 may have increased stretch and / or increased cushioning as compared to the other areas of the central portion. In examples, the inferior strap portion 3318 may have warp elongation in the range of 160%-200%, and the superior strap portion 3316 and lateral sections 3319 may have warp elongation in the range of 110%-150%.

[0240] The example in Fig. 17 is similar to the example in Fig. 15, except that the ribbed textile structure 3390 is provided to the superior strap portion 3316 as well as upper portions 3322 of the lateral sections 3319. All other areas (e.g., inferior strap portion 3318 and lower portions 3324 of the lateral sections 3319) may have a textile structure that is the same as the textile structure of the side portions 3312 as described above with regard to Fig. 13. Thus, the superior strap portion 3316 and the upper portions 3322 may have increased stretch and / or increased cushioning as compared to the other areas of the central portion. This may provide enhanced conformity and shaping in specific areas (e.g., areas of the user's head corresponding to the superior strap portion 3316 and upper portions 3322) of the headgear strap), as well as better accommodation for various head sizes. In examples, the superior strap portion 3316 and upper portions 3322 may have warp elongation in the range of 160%-200%, and the inferior strap portion 3318 and lower portions 3324 may have warp elongation in the range of 110%- 150%.

[0241] The example in Fig. 18 is similar to the example in Fig. 16, except that the ribbed textile structure 3390 is provided to the inferior strap portion 3318 as well as lower portions 3324 of the lateral sections 3319. All other areas (e.g., superior strap portion 3316 and upper portions 3322 of the lateral sections 3319) may have a textile structure that is the same as the textile structure of the side portions 3312 as described above with regard to Fig. 13. Thus, the inferior strap portion 3318 and the lower portions 3324 may have increased stretch and / or increased cushioning as compared to the other areas of the central portion. This may provide enhanced conformity and shaping in specific areas (e.g., areas of the user's head corresponding to the inferior strap portion 3318 and lower portions 3324) of the headgear strap), as well as better accommodation for various head sizes. In examples, the inferior strap portion 3318 and lower portions 3324 may have warp elongation in the range of 160%-200%, and the superior strap portion 3316 and upper portions 3322 may have warp elongation in the range of 110%-150%.

[0242] The example in Fig. 19 is similar to the example in Fig. 13, except that the ribs in the ribbed textile structure 3390 extend in a lateral to contra-lateral direction in use, or otherwise have a horizontal orientation. Due to the horizontal orientation, the ribbed textile structure may have increased stretchability in the width (e.g. height) direction of the headgear strap 3315 as compared to stretchability in the with direction of the vertically oriented ribbed textile structure in Fig. 13. This may allow the headgear strap to comfortably accommodate a range of head sizes by stretching in the width direction as needed. In examples, the central portion 3314 may have warp elongation in the range of 100%-150% and weft (width direction) elongation in the range of 20%-100% depending on the width of the central portion 3314, as shown in Fig. 19.

[0243] Referring to Fig. 20, the ribbed textile structure 3390 (horizontally oriented) extends only along the superior strap portion 3316. All other areas (e.g., inferior strap portion 3318 and lateral sections 3319) of the central portion 3314 may have a textile structure that is the same as the textile structure of the side portions 3312 as described above with regard to Fig. 13. Thus, the superior strap portion 3316 may have increased stretch in the width direction and / or increased cushioning as compared to the other areas of the central portion. In examples, the central portion 3314 may be configured such that the warp elongation of the inferior strap portion 3318 and the lateral sections 3319 is the same as the warp elongation of the superior strap portion 3316. By this arrangement, the central portion 3314 may have uniform lengthwise stretchability, whereas the superior strap portion 3316 may have increased stretchability in the width direction to accommodate a range of head sizes. If necessary, the textile composition of the superior strap portion 3316 and / or the other areas of the central portion may be altered (e.g., addition of stretch fiber, use of monofilament or rigidizing yarns) to achieve the same warp elongation for the inferior strap portion 3318 (and lateral sections 3319) and the superior strap portion 3316. In examples, the superior strap portion 3316 may have warp elongation in the range of 100%-150% and weft elongation in the range of 20%-100% depending on the width of the superior strap portion 3316, and the inferior strap portion 3318 and lateral sections 3319 may have warp elongation in the range of 100%-150%.

[0244] Referring to Fig. 21, the ribbed textile structure 3390 (horizontally oriented) extends only along the inferior strap portion 3318. All other areas (e.g., superior strap portion 3316 and lateral sections 3319) of the central portion 3314 may have a textile structure that is the same as the textile structure of the side portions 3312 as described above with regard to Fig. 13. Thus, the inferior strap portion 3318 may have increased stretch in the width direction and / or increased cushioning as compared to the other areas of the central portion. In examples, the central portion 3314 may be configured such that the warp elongation of the superior strap portion 3316 and the lateral sections 3319 is the same as the warp elongation of the inferior strap portion 3318. By this arrangement, the central portion 3314 may have uniform lengthwise stretchability, whereas the inferior strap portion 3318 may have increased stretchability in the width direction to accommodate a range of head sizes. If necessary, the textile composition of the inferior strap portion 3318 and / or the other areas of the central portion may be altered (e.g., addition of stretch fiber, use of monofilament or rigidizing yarns) to achieve the same warp elongation for the superior strap portion 3316 (and lateral sections 3319) and the inferior strap portion 3318. In examples, the inferior strap portion 3318 may have warp elongation in the range of 100%-150% and weft elongation in the range of 20%-100% depending on the width of the inferior strap portion 3318, and the superior strap portion 3316 and lateral sections 3319 may have warp elongation in the range of 100%-150%.

[0245] The example in Fig. 22 is similar to the example in Fig. 20, except that the ribbed textile structure 3390 extends across or forms the superior strap portion 3316 as well as upper portions 3322 of the lateral sections 3319. All other areas (e.g., inferior strap portion 3318 and lower portions 3324 of the lateral sections 3319) may have a textile structure that is the same as the textile structure of the side portions 3312 as described above with regard to Fig. 13. Thus, the superior strap portion 3316 and the upper portions 3322 may have increased stretch in the width direction and / or increased cushioning as compared to the other areas of the central portion. This may provide enhanced comfort and a snug fit that stays in place while providing the ability to stretch in the width direction to comfortably accommodate different head shapes and sizes. In examples, the superior strap portion 3316 and upper portions 3322 may have warp elongation in the range of 100%-150% and weft elongation in the range of 20%-150% depending on the width of the superior strap portion and upper portions 3322, and the inferior strap portion 3318 and lower portions 3324 may have warp elongation in the range of 100%- 150%.

[0246] Th example in Fig. 23 is similar to the example in Fig. 21, except that the ribbed textile structure 3390 extends across or forms the inferior strap portion 3318 as well as lower portions 3324 of the lateral sections 3319. All other areas (e.g., superior strap portion 3316 and upper portions 3322 of the lateral sections 3319) may have a textile structure that is the same as the textile structure of the side portions 3312 as described above with regard to Fig. 13. Thus, the inferior strap portion 3318 and the lower portions 3324 may have increased stretch in the width direction and / or increased cushioning as compared to the other areas of the central portion. This may provide enhanced comfort and a snug fit that stays in place while providing the ability to stretch in the width direction to comfortably accommodate different head shapes and sizes. In examples, the inferior strap portion 3318 and lower portions 3324 may have warp elongation in the range of 100%-150% and weft elongation in the range of 20%-150% depending on the width of the inferior strap portion 3318 and lower portions 3324, and the superior strap portion 3316 and upper portions 3322 may have warp elongation in the range of 100%-150%.

[0247] Turning to Fig. 24, the central portion 3314 of headgear strap 3315 may include an inner portion 3334 that surrounds (or at least partially surrounds) the slit 3313 and an outer portion 3336 that is disposed between the inner portion 3334 and the superior and inferior edges 3372, 3374 of the central portion 3314 (e.g., the outer portion 3336 surrounds (or at least partially surrounds) the inner portion 3334). The inner portion 3334 may have an oval or elliptical shape and may extend to the side portions 3312. The inner portion 3334 and the outer portion 3336 may have different physical properties and / or characteristics. For example, the inner portion may have different stretchability as compared to the outer portion (e.g., due to differing textile structures and / or textile composition). In the illustrated example of Fig. 24, the inner portion 3334 may have increased lengthwise stretchability as compared to the outer portion 3336. The inner portion 3334 may include a ribbed textile structure 3390 in a vertical orientation to enhance stretchability in the lengthwise direction. A suitable yarn count for the inner portion 3334 may be in the range of 50-140 denier (D) (e.g., 60-120D, 70-110D, 80-100D, 60-90D, or 100-140D). The outer portion 3336 may have a textile structure that includes interlock, plain jersey, pique, pearl knit, waffle knit, plain weave, twill weave, adjacent weaves, and / or satin weave, etc.) to minimize stretch relative to the inner portion 3334, e.g. to provide lesser extension stiffness / elasticity in the outer portion 3336 than in the inner portion 3334. In some examples, the outer portion 3336 may include a ribbed textile structure 3390 (e.g., a rib knit, e.g., 1x1) or hollow ribbed textile structure 3393, and if necessary, the textile composition of the inner portion 3334 and / or the outer portion 3336 may be altered (e.g., addition of stretch fiber, use of monofilament or rigidizing yarns) to achieve the desired stretch arrangement (i.e., the inner portion 3334 having increased stretchability as compared to the outer portion 3336). A suitable yarn count for the outer portion 3336 may be in the range of 70-200D (e.g., 90-180D, 110-160D, 130-140D, 90-130D, or 130-180D). The arrangement of the inner portion and the outer portion may help the headgear strap comfortably conform to the user's head while staying in place on the user's head in use. This arrangement may also help prevent the headgear strap from folding during use. In examples, the inner portion 3334 may have warp elongation in the range of 160%-200%, and the outer portion 3336 may have warp elongation in the range of 75%-150%.

[0248] The example in Fig. 25 is similar to the example in Fig. 24, except that arrangement of the textile structures for the inner portion 3334 and the outer portion 3336 is opposite to that in Fig. 24. That is, in Fig. 25, the outer portion 3336 includes the ribbed textile structure 3390 in vertical orientation to enhance relative stretchability of the outer portion (as compared to the inner portion) in the lengthwise direction. The inner portion 3334 may include the same textile structure described above for the outer portion 3336 in Fig. 24. This arrangement (e.g., the relatively higher stretch along the superior and inferior edges 3372, 3374 of the headgear strap 3315) may help to prevent the headgear strap from shrinking or reducing in size over the period of use. In examples, the inner portion 3334 may have warp elongation in the range of 75%-150%, and the outer portion may have warp elongation in the range of 160%-200%.

[0249] The example in Fig. 26 is similar to the example in Fig. 24, except that the ribbed textile structure 3390 of the inner portion 3334 is oriented horizontally. Thus, the inner portion 3334 may have increased stretchability in the width direction as compared to the outer portion. In examples, the inner portion 3334 may have warp elongation in the range of 100%-150% and weft elongation in the range of 20%-150% depending on the width of the inner portion, and the outer portion 3336 may have warp elongation in the range of 75%-150%.

[0250] The example in Fig. 27 is similar to the example in Fig. 25, except that the ribbed textile structure 3390 of the outer portion 3336 is oriented horizontally. Thus, the outer portion 3336 may have increased stretchability in the width direction as compared to the inner portion. In examples, the inner portion 3334 may have warp elongation in the range of 75%-150%, and the outer portion 3336 may have warp elongation in the range of 100%-150% and weft elongation in the range of 20%-150% depending on the width of the outer portion 3336.

[0251] The example in Fig. 28 is similar to the example in Fig. 13, except that the slit 3313 is eliminated such that the entire central portion 3314 moves together as a unitary piece and, for example, may be formed with unitary construction.

[0252] The example in Fig. 29 is similar to the example in Fig. 19, except that the slit 3313 is eliminated such that the entire central portion 3314 moves together as a unitary piece and, for example, may be formed with unitary construction.

[0253] The example in Fig. 30 is similar to the example in Fig. 24, except that the slit 3313 is eliminated such that the entire central portion 3314 moves together as a unitary piece. The warp elongation of the inner portion 3334 in the Fig. 30 example may be reduced as compared to the Fig. 24 example. In examples according to Fig. 30, the inner portion 3334 may have warp elongation in the range of 110%-200%, and the outer portion 3336 may have warp elongation in the range of 50%-75%.

[0254] The example in Fig. 31A is similar to the example in Fig. 25, except that the slit 3313 is eliminated such that the entire central portion 3314 moves together as a unitary piece. The warp elongation of the inner portion 3334 in the Fig. 31A example may be reduced as compared to the Fig. 25 example. In examples according to Fig. 31A, the inner portion 3334 may have warp elongation in the range of 50%-75%, and the outer portion 3336 may have warp elongation in the range of 110%-200%.

[0255] The example in Fig. 31B is similar to the example in Fig. 31A, except that the inner portion 3334 is provided with a mesh structure 3321 as described elsewhere herein, such as with reference to Fig. 14B. In some examples the mesh structure 3321 is configured to leave the overall extensibility of the outer portion 3336 substantially unaffected, and instead the mesh structure 3321 provides the central portion 3314 with an inner portion which is more breathable than the example of Fig. 31A.

[0256] In other examples the selection of monofilament or multifilament yarns in the mesh structure 3321 may be used to control or adjust the warp and weft elongation in the central portion 3314 as described herein. For example the thickness, material selection or angles of the yarns may be used to limit or otherwise alter the warp and weft elongation characteristics.

[0257] In the illustrated example the mesh structure 3321 comprises a series of overlapping yarns provided at an angle with respect to the vertical or inferior-superior direction of the headgear strap 3315. For example, each of the yarns may be provided at between 60 degrees and -60 degrees inclusive with respect to the vertical or inferior-superior direction, such as approximately 45 degrees. It should be appreciated that the angle of the yarns may be structured to control or limit the extension of the inner portion 3334.

[0258] The example in Fig. 32A is similar to the example in Fig. 27, except that the slit 3313 is eliminated such that the entire central portion 3314 moves together as a unitary piece. The warp elongation of the inner portion 3334 in the Fig. 32A example may be reduced as compared to the Fig. 27 example. In examples according to Fig. 32A, the inner portion 3334 may have warp elongation in the range of 50%-75%, and the outer portion 3336 may have warp elongation in the range of 110%-200%.

[0259] The example in Fig. 32B is similar to the example in Fig. 32A, except that the inner portion 3334 is provided with a mesh structure 3321 as described elsewhere herein, such as with reference to Fig. 14B. In one example the mesh structure 3321 is configured to leave the overall extensibility of the outer portion 3336 substantially unaffected, and instead the mesh structure 3321 provides the central portion 3314 with an inner portion which is more breathable than the example of Fig. 32A.

[0260] In other examples the selection of monofilament or multifilament yarns in the mesh structure 3321 may be used to control or adjust the warp and weft elongation in the central portion 3314 as described herein. For example the thickness, material selection or angles of the yarns may be used to limit or otherwise alter the warp and weft elongation characteristics. In the illustrated example the mesh structure 3321 comprises a series of overlapping yarns provided at an angle with respect to the vertical or inferior-superior direction of the headgear strap 3315. For example, each of the yarns may be provided at between 60 degrees and -60 degrees inclusive with respect to the vertical or inferior-superior direction, such as approximately 45 degrees. It should be appreciated that the angle of the yarns may be structured to control or limit the extension of the inner portion 3334.

[0261] The example in Fig. 33 is similar to the example in Fig. 26, except that the slit 3313 is eliminated such that the entire central portion 3314 moves together as a unitary piece. In examples according to Fig. 33, the inner portion 3334 may have warp elongation in the range of 110%-200%, and the outer portion 3336 may have warp elongation in the range of 50%-100%.

[0262] Referring to Fig. 34, the central portion 3314 of the headgear strap 3315 may have alternating vertically arranged sections having different textile structures. For example, a plurality of first vertical sections 3331 may be alternately disposed with a plurality of second vertical sections 3333. The first vertical sections 3331 may have a textile structure that is the same as the textile structure of the side portions 3312 as described above with regard to Fig. 13. The second vertical sections 3333 may include the ribbed textile structure 3390 and thus may have at least increased lengthwise stretchability as compared to the first vertical sections 3331. The size (e.g., length (in lengthwise direction)) of each individual vertical section may vary to adjust the overall stretch as desired. Thus, in the Fig. 34 example, the headgear strap 3315 comprises a plurality of ribbed textile structure 3390 spaced apart / separated by a spacing. In examples, the first vertical sections 3331 may have warp elongation in the range of 50%-75%, and the second vertical sections 3333 may have warp elongation in the range of 110%- 200%. It should be appreciated that while this example is described with respect to alternating vertically arranged sections, it could equally be applied to alternating horizontally arranged sections as described herein.

[0263] The ribbed textile structure 3390, or any of the features of a strap described with reference to Figs. 11A to 34, may be provided to any strap portion of a positioning and stabilising structure 1300 described with reference to Figs. 1A-10B. The positioning and stabilising structure 1300 may be constructed and arranged such that the headgear strap 3315 comprises a central portion configured to engage a posterior portion (e.g. overlying the occipital bone and / or parietal bones), a superior portion (e.g. overlying the parietal bones and / or frontal bones) or an anterior portion (e.g. overlying the frontal bone, e.g. the forehead) of the user's head in use.

[0264] In some examples, the rear section 1030B of the positioning and stabilising structure 1030 of the eye mask 1000 shown in Figs. 1A-1B comprises a ribbed textile structure 3390 or headgear strap 3315 as described herein.

[0265] In some examples, either or both of the first bifurcated section 7070A and the second bifurcated section 7070B of the positioning and stabilising structure 7030 shown in Figs. 7A-7C comprises a ribbed textile structure 3390 or headgear strap 3315 as described herein.

[0266] In some examples, either or both of the first bifurcated section 8070A and second bifurcated section 8070B of the positioning and stabilising structure 8030 shown in Figs 8A and 8B comprises a ribbed textile structure 3390 or headgear strap 3315 as described herein.

[0267] In some examples, either a posterior portion or anterior portion of the first section 9072 of the positioning and stabilising structure of the eye mask 9000 shown in Figs 9A-9C comprises a ribbed textile structure 3390 or headgear strap 3315 as described herein.

[0268] Variable Extensibility of Straps

[0269] Fig. 35 shows an example of a connecting portion 3500 of a positioning and stabilising structure 1300. The connecting portion 3500 may be configured to connect the positioning and stabilising structure to an eye component of an eye mask, such as any eye component of any eye mask disclosed herein.

[0270] As shown the connecting portion includes a first end 3602 which is configured to facilitate connection to the eye component, and a second end 3604, which may be connected to another strap portion of the positioning and stabilising structure 1300 such as a strap portion overlying a posterior portion, superior portion or anterior portion of the user's head. In some examples the first end 3602 may be provided with a connection member (not shown) which is configured to connect to the eye component, while in other examples the first end 3602 may be configured to pass through an aperture in the eye component, and loop back onto itself. For example the connecting portion 3500 may be provided with a hook and loop fastener, for example an unbroken loop region 3612 may be provided in the outwardly, non-user contacting side of the connecting portion 3500, and a hook region 3614 may be provided on or adjacent to the first end 3602 (or vice versa), to thereby provide co-operating hook-and-loop regions (known commonly as under the trademark Velcro). Once the appropriate tension is set by the user, the first end 3602 may be positioned appropriately on the unbroken loop portion of the connecting portion 3500 to maintain the tension.

[0271] In the illustrated example the first end 3602 of the connecting portion 3500 is provided with rounded corners 3605. These rounded corners 3605 may advantageously allow the first end 3602 to be more easily inserted through the aperture in the eye component.

[0272] The connecting portion 3500 is also provided with a rounded-edge profile, such that the edges of the connecting portion 3500 lift outwardly from the skin of the user, which in some examples can aid to reduce occurrences of pressure sores and facial marking. For example, the rounded-edge profile may be provided using thermoforming, or other similar process. This rounded-edge profile may also be used in other straps of the headgear as described herein.

[0273] In some examples of the technology, the connecting portion may be divided into a first region 3606 having a first stretch characteristic and a second region 3608 having a second stretch characteristic. For example, the second region may be configured to have greater stretch or extensibility in a length or longitudinal direction 'L' than the first region. For example, the second region may be configured to have a maximum elongation in the range of 110%-200%, and the first region may be configured to have a maximum elongation in the range of 50%-75%.

[0274] In some examples the connecting portion 3500 may have a length (measured in the longitudinal axis L) of between approximately 140 mm to 40 mm, wherein the first region 3606 takes between approximately 80% and 90% of the total length. For example, the connecting portion may have a length of approximately 90mm wherein the first region has a length 3606 of approximately 80mm and the second region 3608 has a length of approximately 10mm.

[0275] In examples, the connecting portion may have a width which is measured substantially perpendicular to the longitudinal axis of between approximately 20mm and approximately 50mm, such as approximately 40mm. Use of a relatively wide connecting portion 3500 may advantageously aid in maintaining the eye component in a stable position on the user's face during use. By providing these first 3606 and second regions 3606 having differing stretch / extensibility characteristics it may be possible to provide connecting portions 3500, which are easier to use, and can allow for some movement of the eye component in use while maintaining effective engagement with the user's face.

[0276] Furthermore, by positioning the unbroken loop material across the majority of the first region 3606 with comparatively low stretchability, the performance of the hook and loop fastener may be more reliable, and less prone to slipping during use.
