Docket No. 406682-555001 WO PCT Patent ApplicationSLING FOR AN INFANT BATHTUBCROSS REFERENCE TO RELATED APPLICATIONS

[0001] This application claims the benefit of priority to United States (US) provisional application Serial No. 63 / 728,122, filed 04-December-2024, the entire disclosure of which is incorporated by reference as if fully set forth herein in its entirety.FIELD OF THE INVENTION

[0002] The present disclosure relates to a sling for infant bathtubs, designed to provide stability, safety, and security.BACKGROUND OF THE INVENTION

[0003] Throughout human history, the care and bathing of human newborns and young infants has presented unique safety challenges. Since the early twentieth century, parents and caregivers have sought ways to support very small, slippery bodies in basins and tubs while keeping the infant’s head safely above the water. For much of this period, infants were bathed in ordinary household tubs, basins, or sinks without any specialized support device, relying entirely on the caregiver’s hands and arms. As indoor plumbing became more common and bathtubs became standard fixtures, the risk of accidental slips and submersion during bathing became an increasing concern.

[0004] By the mid-1960s, various infant bath basins and “baby baths” began to appear, often formed as small plastic tubs designed to sit in a larger bathtub or on a countertop. These early products primarily addressed size and containment but generally did not include integrated safety structures. Newborns were still typically cradled directly in the caregiver’s arms or positioned on a simple molded surface, offering limited assistance in maintaining posture or preventing rolling.

[0005] Later in the twentieth century, manufacturers introduced more contoured infant bath inserts with shallow, reclined shapes and / or foam / inflatable pillows intendedDocket No. 406682-555001 WO PCT Patent Application to better support the infant’s body. Some of these also included foam pads, non-slip surfaces, or raised sections to help keep the head above water. However, these rigid or semi-rigid supports could be uncomfortable, slow to dry, fungus prone, and not easily adaptable to different infant sizes or developmental stages. Their fixed geometry also limited how close the infant could be held or how the bathing position could be adjusted as the child grew. These limitations made many of these products disposable.

[0006] Importantly, modern parents are extremely busy and cleaning up the tub after the cleaning of the infant or newborn is restricted. Further, as awareness of drowning risks in very shallow water increased, especially for newborns lacking head and neck control, safety considerations became more central in the development of bathing supports. Standards and guidance from regulators, pediatric organizations, and consumer safety bodies emphasized the need to maintain the infant’s head above the waterline, minimize the chance of slipping or sliding downward, and avoid entrapment or strangulation hazards. This prompted design refinements such as more reliable anchoring methods, improved body-contouring shapes, and reduced use of hard edges or exposed hardware near the infant.

[0007] Under these considerations, extreme challenges remain in providing a support system that is easy for caregivers to install correctly, adaptable to different tub shapes and household setups, easy to clean and / or just let sit to dry, and capable of safely accommodating infants as they grow and develop. There is a continuing need for newborn and infant bathtub solutions that address drowning risk, slipping and rolling risk, caregiver ease-of-use, and practical concerns such as cleaning, drying, and storage, all while integrating smoothly into existing bathing routines and bathroom environments.BRIEF SUMMARY OF THE INVENTION

[0008] The following presents a simplified summary of the innovation in order to provide a basic understanding of some aspects of the invention. This summary is not an extensive overview of the invention. It is intended to neither identify key or criticalDocket No. 406682-555001 WO PCT Patent Application elements of the invention nor delineate the scope of the invention. Its sole purpose is to present some concepts of the invention.

[0009] Infant care products, particularly those designed for bathing, have evolved significantly over the years to enhance safety, comfort, and convenience for both the infant and the caregiver. Bath time can be a challenging experience for new parents, as it requires balancing the infant's safety with the need for effective cleaning, while minimizing distractions. Traditional infant bathtubs often lack features that provide adequate support and security, leading to potential risks such as slipping or discomfort for the infant. As a result, there is a continuous demand for the innovative solutions disclosed herein that address these challenges by offering improved stability and ease of use.

[0010] The design (or safety by forethought) of infant bathing accessories, such as slings, plays a crucial role in ensuring a safe and enjoyable bath time experience. These accessories must be carefully engineered to provide secure support while being easy to install and remove. Additionally, the materials used in these products are of paramount importance, as they need to be durable, water-resistant, and comfortable against the infant's skin. The integration of features that allow for quick drying and easy maintenance further enhances the practicality of these products. As parents seek more reliable and user-friendly options, the development of advanced infant bathing solutions remains a key focus in the market.

[0011] In accordance with some embodiments, a sling is provided for an infant bathtub, the bathtub which includes a rim. The sling comprises a top side designed to support an infant and a bottom side. The bottom side features a first end with a flap that encloses a portion of one end of the rim. Additionally, the bottom side includes a second end with opposite comers, each corner having a strip attached to it. This configuration forms an inner and an outer loop, with each corner also having a clip attached to the strip. The clip is designed with a closed slot at one end to receive the outer loop, an open slot at the other end for removably receiving the inner loop, and a flange to engage opposite sides of the rim.

[0012] In accordance with other embodiments, the sling can be comprising a porous fabric material. In one summary embodiment (non-limiting) the technology can beDocket No. 406682-555001 WO PCT Patent Application discussed as a sling for an infant bathtub including dual-configuration loop and a clip assembly. According to some aspects, the porous material can be a quick-drying material.

[0013] Infant bathtub slings have traditionally been constructed from a single piece of fabric or mesh that drapes across the basin and is secured to the rim by sliding edge sleeves or simple loops over the tub sides. These fixed— loop slings provide only one stable support angle, requiring full removal and rethreading of the fabric sleeves to change the sling’s inclination or height.

[0014] To introduce adjustability, some designs employ individual canvas straps at each corner of the sling panel, with each strap routed through buckles, cord locks, or a series of stitched loops. Unfortunately, these straps attach to fixed locations and are often insecure.

[0015] In an effort to simplify attachment and removal, other slings have incorporated quick — release clips, such as carabiner — style hooks, snap — fit buckles, or spring — loaded clasps at the strap ends. These clip— based systems sometimes offer a few preset strap holes to select different heights, but they tend to add bulk at the corners and still lack a straightforward way to switch between distinctly tailored newborn and infant positions without detaching and reattaching multiple fasteners.

[0016] None of these approaches have provided a comprehensive solution that combines the features described in this disclosure. Previous approaches have never provided a comprehensive solution that combines the multiple (inter-combinable) features described in this disclosure. In some embodiments, the technology disclosed herein can provide a bathing assembly including adjustments to safely meet cleaning needs of a unique infant or a unique newborn.

[0017] Now after the introduction above, this summary provides a high-level overview of example sling systems, clips, kits, and methods that may be implemented alone or in combination as set forth elsewhere in this specification. In some embodiments, a sling is provided for an infant bathtub having a basin and a surrounding rim. A flexible sling body spans the basin and is supported on the rim so as to define an elevated support surface for a newborn or infant. According to some aspects, the slingDocket No. 406682-555001 WO PCT Patent Application body includes a top side configured to cradle the infant and a bottom side carrying attachment hardware and loops that cooperate with a rim-engaging clip system.

[0018] In some embodiments, the sling body includes a head end and a foot end. The head end is secured to the rim by a flap that wraps over and optionally around a portion of the rim, distributing load over a broad region and avoiding rigid hardware in the head zone. The foot end is secured by one or more clips attached at opposite corners via strips forming looped strap portions. This head-flap I foot-clip geometry allows the sling to be anchored to generic tub rims while maintaining a soft headsupport region.

[0019] According to some aspects, each clip comprises a body with at least one closed slot, an open slot, and a hooked flange. A strip attached to the sling forms an outer loop and an inner loop. The outer loop is permanently threaded through the closed slot, while the inner loop is selectively engageable with the open slot. When the inner loop is received in the open slot, the sling assumes a raised newborn contour that suspends the infant support region above the basin floor. When the inner loop is released from the open slot, the sling relaxes into a lowered infant sling position, suitable for larger or more active infants, without removing the clip from the rim.

[0020] In further embodiments, the strip forms three or more loops, including an outer loop and multiple inner loops. A single clip with closed and open slots cooperates with these loops to provide three or more discrete, repeatable support positions. Engagement of different inner loops in the open slot yields a corresponding sequence of height and recline-angle settings, allowing gradual transitions as the infant grows. Visual indicators on the strip or clip may identify recommended positions for different infant stages or weight ranges.

[0021] In some embodiments, an alternative or additional adjustment mechanism is provided using a fabric-gathering loop. A loop of fabric at an edge of the sling passes under or around the rim and engages a secondary mounting location on the clip body. When engaged, the loop gathers fabric into a compact band, creating a hammock-like newborn contour in which side edges are higher than a central region. When released from the secondary mounting location, the gathered fabric relaxes into a released loop, lengthening the sling edge and defining a lowered contour. This gathered-fabricDocket No. 406682-555001 WO PCT Patent Application mechanism may be used instead of, or in combination with, the loop-and-slot system to shape the sling.

[0022] According to some aspects, the clip body is configured as a generic rimengaging hardware component usable with a variety of flexible members. The hooked flange engages opposite sides of a rim without requiring molded receivers or protrusions on the tub. Optional insert pads may be provided on interior contact surfaces of the flange to improve grip and accommodate different rim thicknesses. The same clip geometry can therefore be applied to infant slings, pet baths, sink-mounted supports, and other flexible structures that are tensioned over a rim.

[0023] In some embodiments, the sling body includes a porous or mesh top side that provides a breathable support surface. The mesh may be a three-dimensional spacer fabric or another water-permeable textile that allows rapid drainage from the infant’s body while remaining soft and conforming. Edge regions of the mesh may be folded and bound to the bottom side to create a soft perimeter at the rim interface. Treatments may be applied to reduce mildew, odor, or drying time.

[0024] According to additional aspects, the technology encompasses kits and methods. A kit may include an infant bathtub and a sling configured as described above, or may include only the sling and clip hardware for retrofitting third-party tubs.Instructions may describe installation of the sling on the rim, adjustment between newborn and infant positions, and recommended water depths or use conditions. Methods may include installing the sling on a tub rim, supporting a newborn above water using the sling, transitioning the sling from a newborn contour to an infant contour as the child develops, and using gathered contours to reduce rolling or rotation during bathing.

[0025] In some embodiments, the systems and methods disclosed herein are configured to be evaluated under harmonized safety protocols that address static load retention, tipping stability, water-submersion limits, entrapment hazards, and durability over repeated laundering and use. The sling geometries, clip structures, head-end flap, porous mesh, and optional adjustment mechanisms are intended to be freely combinable, except where technically incompatible, so that a wide range of product variants can be derived from the teachings of this disclosure.Docket No. 406682-555001 WO PCT Patent Application

[0096] In a non-limiting example, some various embodiments of the sling for an infant bathtub and their advantages can be understood by referring to FIGs. 1A through 5C of the drawings. The elements of the drawings are not necessarily to scale, emphasis instead being placed upon clearly illustrating the novel features and principles of operation. Throughout the drawings, like numerals are used for like and corresponding parts of the various drawings.

[0097] Furthermore, reference in the specification to “an embodiment,” “one embodiment,” “various embodiments,” or any variant thereof means that a particular feature or aspect described in conjunction with the particular embodiment is included in at least one embodiment. Thus, the appearance of the phrases “in one embodiment,” “in another embodiment,” or variations thereof in various places throughout the specification are not necessarily all referring to its respective embodiment.

[0098] In some embodiments, FIGs. 1A and 1 B illustrate an exemplary infant sling 100 positioned on an infant bathtub 111 over the basin 102 defined therein. FIG. 1ADocket No. 406682-555001 WO PCT Patent Application shows the sling 100 in a first configuration wherein the lower end is slack, and FIG. 1B shows the sling 100 in a second configuration where the lower end is taut. In the second configuration, an infant would be supported in a more horizontal position, while in the first configuration, the infant would be supported in a partially reclined position.

[0099] In another example, FIG. 1A illustrates a sling (100) supported on an infant bathtub such that the sling overlies a basin (102) and engages an outer rim of the tub (111 ). The sling (100) is shown in a loosened or slack contour (155), which corresponds to a lowered infant sling position (155). In some embodiments, the slack contour (155) allows the sling (100) to sag deeper into the basin (102) so that a larger or more developmentally advanced infant can be partially surrounded by water while still being supported off the tub floor. According to some aspects, the outer rim of the tub (111 ) is generally continuous around the basin (102) and receives a flap or clip arrangement (described elsewhere) that anchors the sling (100) on opposite sides of the tub while allowing the central portion of the sling to hang in the loosened or slack contour (155). In this configuration, the sling (100) may be used as an “older infant” position, with the basin (102) filled to a depth that remains below the infant’s head while the infant reclines in the lowered infant sling position (155) defined relative to the outer rim of the tub (111 ).

[0100] In this example, FIG. 1 B illustrates the same sling (100) and basin (102) arrangement supported by the outer rim of the tub (111 ), but here the sling (100) is shown in a taut contour (150). The taut contour (150) corresponds to a first position (150) that is higher for a newborn, in which the sling (100) spans more tightly between attachment points on the outer rim of the tub (111 ). In some embodiments, fabric at the foot end of the sling (100) is gathered and shortened so that the newborn-support region is elevated relative to the basin (102), thereby reducing water depth around the newborn and limiting sliding motion toward the tub floor. According to some aspects, the taut contour (150) defines a more pronounced hammock-like shape in which the head end is adjacent the outer rim of the tub (111 ) and the body region is supported above the basin (102), while the sling (100) remains tensioned across the rim. In this newborn configuration, water can be added to the basin (102) while maintaining the newborn’sDocket No. 406682-555001 WO PCT Patent Application head above the waterline and at a height governed by the taut contour (150) relative to the outer rim of the tub (111 ).

[0101] In some embodiments, FIGs. 2A and 2B show the sling 100 in perspective views showing the first configuration and second configuration, respectively. As will be explained in detail hereafter, the difference between the slack condition and the taut position of the sling is in how the opposite corners of the sling engage with the rim of the tub 111.

[0102] In other embodiments, FIG. 2A illustrates a view of a sling (100) supported on an infant bathtub having a basin (102) and an outer rim of the tub (111 ). The sling (100) extends across the open top of the basin (102) and is anchored along the outer rim of the tub (111 ) by head-end and foot-end attachment structures as described elsewhere. In FIG. 2A, the sling (100) is shown in a loosened or slack contour (155), which corresponds to a lowered infant sling position (155). According to some aspects, the loosened or slack contour (155) is achieved when adjustment loops or gathered fabric portions at the foot end are released, allowing the central region of the sling (100) to hang deeper toward the bottom of the basin (102). In some embodiments, the lowered infant sling position (155) provides a more open and relaxed support suitable for larger or more developmentally advanced infants, while still maintaining separation between the infant and the basin (102) floor. The outer rim of the tub (111 ) provides a continuous reference outline in FIG. 2A, showing how the sling (100) in the loosened or slack contour (155) occupies a lower effective position within the footprint of the basin (102) as compared with a more elevated newborn configuration depicted in other figures.

[0103] According to some aspects, FIG. 2B illustrates a corresponding view of the same sling (100), basin (102), and outer rim of the tub (111 ), but here the sling (100) is shown in a taut contour (150). The taut contour (150) represents a first position (150) that is higher for a newborn. According to some aspects, the taut contour (150) is obtained when adjustable loop or fabric-gathering features at the foot end are engaged so that the sling (100) spans more tightly between attachment points on the outer rim of the tub (111 ). In FIG. 2B, the geometry of the sling (100) relative to the basin (102) and the outer rim of the tub (111 ) is similar to FIG. 2A, but the effective support level is elevated in the first position (150) that is higher for a newborn. In some embodiments,Docket No. 406682-555001 WO PCT Patent Application this configuration is used when additional elevation and a more cradling posture are desired, with the taut contour (150) reducing the effective water depth around the newborn and helping to maintain the newborn’s head and upper body at a higher level within the overall outline defined by the outer rim of the tub (111 ).

[0104] In a non-limiting example, now with a reference to FIG. 3A, the reverse or bottom side 301 of sling 100 comprises a flap 307 at a first end for enclosing a portion of the rim of the bathtub at one end thereof. A second end of the sling 100 comprises opposite corners 309a, b. Each corner comprises a strip 303a, b that is attached to the bottom side of sling 100. A clip 305a, b is attached to each strip 303a, b.

[0105] In some embodiments, FIG. 3A illustrates the bottom side of a sling (100) configured for use with an infant bathtub. The sling (100) is shown inverted such that the bottom side of the sling (301 ) is visible, exposing attachment elements that are ordinarily concealed during use. At a head end, a flap (307) extends from the bottom side of the sling (301 ) and is configured to wrap over a rim of a tub to anchor the head end without rigid hardware at that location. According to some aspects, the flap (307) may be stitched or otherwise secured along a transverse region of the bottom side of the sling (301 ) so that loads applied by a newborn’s head and upper torso are distributed along the supporting rim. At an opposite, second end of the sling (100), two corners are defined as opposite corners of the second end of the sling (309a, 309b). In some embodiments, each of these opposite corners (309a, 309b) carries a respective strip (303a, 303b) attached to the bottom side of the sling (301 ). The strips (303a, 303b) extend beyond the edges of the sling (100) to form loops and to connect to respective clips (305a, 305b). The clips attached to strips 303a, 303b (305a, 305b) provide adjustable engagement with a tub rim, such that the second end of the sling (100) can be tensioned or relaxed while the head end remains positioned via the flap (307). This bottom-side view clarifies the relationship between the sling fabric, the opposite corners (309a, 309b), the strips (303a, 303b), and the clips (305a, 305b) that collectively define the adjustable support geometry.

[0106] According to some aspects, FIG. 3B illustrates a side view focusing on the head end of the sling (100) in relation to an outer rim of a tub (111 ) and an underlying basin (102). The sling (100) extends over the basin (102) so that the central supportDocket No. 406682-555001 WO PCT Patent Application region spans above the interior of the tub, while a forward edge region at the head end rests on or near the outer rim of the tub (111 ). In some embodiments, the rim of the tub is located underneath part of the sling (100), and the basin (102) is located inside the tub such that water can be contained below the sling. A flap (307) at the head end of the sling (100) is shown draped over the outer rim of the tub (111 ), indicating that this headend attachment relies on the flap (307) enclosing or wrapping the rim rather than on clips or other rigid hardware. According to some aspects, the flap (307) may be stitched along the head-end edge of the sling (100) and dimensioned to fold under or around the outer rim of the tub (111 ), forming a pocket or friction-based engagement region that stabilizes the sling (100) above the basin (102). This figure highlights that the head end of the sling (100) is secured to the outer rim of the tub (111 ) by the flap (307) alone, while any clip-based adjustments occur at the foot end, thereby keeping hardware away from the infant’s head region.

[0107] In some embodiments, as shown in FIGs. 4A and 4B show engagement of clip 305 with the strip 303 in greater detail. Strip 303 is attached to the bottom side 301 of sling 100 such that two loops are formed: an outer loop 404 and an inner loop 402. Clip 305 is configured with a closed slot 405a at one end which, along with closed slot 405b (shown in FIG. 5B), is permanently engaged with outer loop 404. At the other end of clip 305, an open slot 403 is located. As depicted in FIG. 4B, open slot 403 is configured to selectively engage inner loop 402. Strip 303 may be attached to the bottom side 301 of sling 100 such that more than two loops are formed. In this way, the sling 100 may be selectively engaged with the tub 111 in more than just the two configurations described.

[0108] In some embodiments, FIG. 4A illustrates a corner detail of the sling (100) showing how a strip (303) and a clip (305) cooperate in a slack configuration. A strip (303) is attached to the bottom side (301 ) of the sling at a corner region corresponding to a second end corner of the sling (309). The strip (303) is folded and stitched such that two loops are formed, namely an inner loop (402) and an outer loop (404). According to some aspects, the outer loop (404) is routed through a closed slot (405a) at one end of the clip (305), the closed slot (405a) being configured to permanently engage the outer loop (404). In some embodiments, a second closed slot (405b), whichDocket No. 406682-555001 WO PCT Patent Application is not visible in this view, is also engaged with the outer loop (404) to provide additional security. At an opposite end of the clip (305), an open slot (403) is provided and configured for removably receiving the inner loop (402). In the slack configuration depicted in FIG. 4A, the inner loop (402) may be disengaged or only partially engaged with the open slot (403), thereby allowing the corner region (309) of the sling (100) to assume a longer effective length relative to the clip (305). This arrangement contributes to the loosened or lowered contour described in connection with other figures, while still maintaining the connection between the strip (303), the loops (402, 404), and the clip (305) at the bottom side (301 ) of the sling.

[0109] According to some aspects, FIG. 4B illustrates the same corner region (309) of the sling (100) in a taut configuration. As in FIG. 4A, the strip (303) is attached to the bottom side (301 ) of the sling at the second end corner (309) and forms both an inner loop (402) and an outer loop (404). The outer loop (404) again passes through the closed slot (405a) of the clip (305), with a further closed slot (405b) (not visible in this view) also engaged with the outer loop (404) to define a permanent connection. The open slot (403) at the opposite end of the clip (305) is here shown as removably receiving the inner loop (402). When the inner loop (402) is fully seated within the open slot (403), the effective distance between the corner region (309) of the sling (100) and the clip (305) is shortened, thereby tightening the sling fabric at that location. In some embodiments, engagement of the inner loop (402) within the open slot (403) on clips at both opposite corners produces the taut newborn contour depicted elsewhere, with the bottom side (301 ), strip (303), and loops (402, 404) cooperating to elevate the sling relative to the tub rim.

[0110] In some embodiments, FIG. 4C illustrates a top view of gathered fabric in a taut configuration of the sling (100). A region of gathered fabric (500) is shown adjacent a clip (305) that is mounted along a tub rim (111 ). The clip (305) includes a hooked flange (501 ) that engages the underside of the tub rim (111 ), although the hooked flange (501 ) is located beneath the rim in this view. According to some aspects, tension applied through the clip (305) draws the edge of the sling toward the tub rim (111 ), causing the fabric to bunch into the gathered fabric (500). This gathering shortens the effective span of the sling along the rim and contributes to formation of a taut contourDocket No. 406682-555001 WO PCT Patent Application(150). In this example, the taut contour (150) defines a first position (150) that is higher for a newborn, elevating the central support region of the sling relative to the basin (102) while the edge region near the gathered fabric (500) follows the shape of the tub rim (111 ). The top view of FIG. 4C thus shows how the clip (305), the hooked flange (501 ), and the gathered fabric (500) cooperate along the tub rim (111 ) to establish the taut contour (150) corresponding to the first position (150) that is higher for a newborn.

[0111] According to some aspects, FIG. 4D illustrates a bottom clip-view of the same gathered fabric arrangement in the taut configuration. From this underside perspective, gathered fabric (500) is located between the sling body and the tub rim (111 ), with a loop of fabric (engaged loop 420) extending toward and around a clip (305). The clip (305) again includes a hooked flange (501 ) that hooks over opposite sides of the tub rim (111 ), securing the assembly to the tub. In some embodiments, the loop of fabric (engaged loop 420) passes under or around the tub rim (111 ) and is engaged by the clip (305) so that tightening of the loop of fabric (engaged loop 420) draws additional material into the gathered fabric (500). According to some aspects, this interaction between the loop of fabric (engaged loop 420), the gathered fabric (500), the clip (305), and the hooked flange (501 ) maintains the sling edge in a taut contour (150) that defines the first position (150) that is higher for a newborn along the tub rim (111 ). The bottom clip-view of FIG. 4D therefore emphasizes how the loop of fabric (engaged loop 420) and gathered fabric (500) cooperate with the clip (305) and hooked flange (501 ) on the tub rim (111 ) to sustain the taut newborn-support configuration.

[0112] In some embodiments, FIG. 4E illustrates a top view of a gathered fabric region in a newborn configuration of the sling. A taut contour (150) extends across the edge of the sling to define a first position (150) that is higher for a newborn. Along this edge, a concentrated band of gathered fabric (500) is visible, representing material that has been drawn in from the surrounding sling body and shortened relative to a relaxed condition. In some embodiments, the gathered fabric (500) is produced when an underlying loop of fabric and associated clip mechanism are engaged, as shown in other figures, so that the effective span of the sling edge is reduced and the central support region is lifted. The taut contour (150) thus traces the perimeter of the newbornsupport configuration, while the gathered fabric (500) indicates where excess materialDocket No. 406682-555001 WO PCT Patent Application has been taken up to create this raised profile. In use, the taut contour (150) and gathered fabric (500) cooperate to hold the newborn at an elevated level above the water in the basin, while still providing a soft, compliant interface along the sling edge.

[0113] According to some aspects, FIG. 4F illustrates a corresponding top view after the gathered region has been released to form a lowered infant configuration. A released fabric (505) is shown extending along the sling edge where the material was previously gathered. In some embodiments, the released fabric (505) is produced when a fabric loop is disengaged from an adjustment feature of the clip, allowing the edge fabric to lengthen and spread out. As a result, the sling assumes a lowered infant sling position (155) in which the support surface is located deeper within the basin. The lowered infant sling position (155) defines a more relaxed contour suited for larger or more active infants who can safely be positioned closer to the water. The contrast between the compact band of gathered fabric (500) in the newborn configuration and the extended released fabric (505) in FIG. 4F visually illustrates how selective engagement and release of the fabric loop transitions the sling between the higher newborn support and the lowered infant configuration (155).

[0114] In some embodiments, FIG. 4G provides a detailed view of the hardware and fabric arrangement associated with the lowered configuration. A clip (305) is mounted at an edge region of the sling along a tub rim (111 ). The clip (305) includes a hooked flange (501 ) that engages the rim (111 ) to provide primary attachment of the sling to the tub. On a rear portion of the clip (305), a secondary mounting location on the rear clip (508) is provided to interact with a released loop of fabric (same loop in the release state 507). In the condition depicted, the released loop of fabric (same loop in the release state 507) is not engaged with the secondary mounting location (508), allowing a released gathered fabric (505) to extend underneath the sling edge. This arrangement corresponds to the lowered infant sling position (155), in which the sling contour is lengthened and the support surface is positioned lower relative to the rim (111 ). In some embodiments, engaging the released loop of fabric (same loop in the release state 507) at the secondary mounting location (508) would draw the released gathered fabric (505) up around the rim (111 ), re-establishing the newborn raised contour; conversely, the state shown in FIG. 4G demonstrates the fully released, lowered infant sling positionDocket No. 406682-555001 WO PCT Patent Application(155) maintained while the clip (305) remains securely attached to the tub rim (111 ) by the hooked flange (501 ). It is important to note that in FIG 4D and 4G both “loop 420” and “loop 507” appear and they may represent equivalent elements at different stages; in some embodiments, 420 and 507 refer to the same looped fabric segment in different states of engagement.

[0115] In a non-limiting introduction, FIGs 5A through 5C are various views of clip 305 showing closed slots 405a, 405b, and open slot 403 which is configured with an opening for receiving the portion of strip 303 forming inner loop 402. In addition, clip 305 is configuration with a hooked flange 501 . Hooked flange 501 is designed for engaged the rim of bathtub 111.

[0116] When the inner loop 402 are inserted into open slot 403 of both clip 305 and the clips are engaged with the bathtub rim, the sling is in the taut configuration. Conversely, when the inner loop 402 of the strip is not engaged with the open slot, but the clips are engaged with the bathtub rim, the sling is in the slack configuration.

[0117] In some embodiments, FIG. 5A illustrates a perspective view of an exemplary clip (305) configured for attachment to a flexible sling system. The clip (305) includes an open slot (403) located at a second end of the clip body, the open slot (403) being sized and shaped to removably receive a looped strap portion when the sling is adjusted between different support positions. According to some aspects, an entrance of the open slot (403) may be slightly narrowed relative to an interior region to help retain the loop once seated. At an opposite end of the clip (305), a closed slot region one or more closed slots 405a, 405b (or “405”) is provided. The closed slot region (405) corresponds to closed slots that permanently receive an outer loop of a strap or webbing, thereby defining a fixed connection between the strap and the clip body. Extending from a side of the clip (305) is a hooked flange (501 ) that is configured to engage the rim of a bathtub (111 ), for example by capturing both an upper surface and a lower surface of the rim. On a side of the clip (305) opposite the hooked flange (501 ), an opposite wall or side portion (502) forms a continuous outer contour that surrounds the closed slot region (405) and the open slot (403). In some embodiments, the smooth profile of the opposite wall portion (502) reduces snagging of fabric or webbing and improves comfort when the clip (305) is used adjacent to a sling edge.Docket No. 406682-555001 WO PCT Patent Application

[0118] According to some aspects, FIG. 5B presents a plan or top view of the same clip (305), highlighting the relationship between the open slot (403), the closed slots (405a, 405b), and an outer loop (404) of a strap. At a first end of the clip (305), the closed slots (405a, 405b) are arranged side by side and are dimensioned such that the outer loop (404) passes through both closed slots (405a, 405b) to form a permanent threaded engagement. This double-pass configuration can distribute load along the clip body and resist twisting of the outer loop (404) during use. The opposite end of the clip (305) defines the open slot (403), which is configured to selectively receive a second loop of the strap when an adjustable connection is desired. Along the perimeter of the clip (305), a side or body portion (502) is shown encircling the closed slots (405a, 405b) and the open slot (403). In some embodiments, this side / body portion (502) is shaped as a continuous smooth wall to reduce sharp edges and to provide a robust frame around the slots, thereby enhancing both structural strength and user comfort when the clip (305) is handled or when fabric slides across its outer surface.

[0119] In some embodiments, FIG. 5C illustrates a side view of the clip (305) emphasizing how the clip interfaces with a tub rim (111 ). The optional insert pad (600) is provided in case the clip is to be used with a tub rim that is too thin or has not the “generic rim profile”. The clip (305) is depicted with a hooked flange (501 ) extending from the main body and forming a generally C-shaped or hook-shaped profile. The hooked flange (501 ) is configured to engage opposite sides of the rim of the tub (111 ), for example by gripping over an upper lip and under a lower edge of the rim (111 ) so that the clip (305) is retained in place under load transmitted through associated strap loops. In some embodiments, contact surfaces of the hooked flange (501 ) that bear against the rim (111 ) may include textured or high-friction regions to resist sliding along the rim. The side view of FIG. 5C thus clarifies that the clip (305) can be mounted on a generic rim (111 ) without dedicated receivers, with the hooked flange (501 ) providing secure yet removable engagement compatible with a wide variety of infant tub geometries.

[0120] In some embodiments, the optional insert pad (600) comprises: Silicone rubber (e.g., food-grade or medical-grade) - soft, high-friction, and stable in hot water and detergents; Thermoplastic elastomer (TPE) - over-moldable onto clip 305, gives aDocket No. 406682-555001 WO PCT Patent Application grippy, slightly compliant pad; Thermoplastic polyurethane (TPU) - tougher elastomer with good abrasion and hydrolysis resistance; Ethylene-vinyl acetate (EVA) foam - lightweight, compressible foam pad for variable rim thicknesses; Closed-cell polyethylene foam - buoyant, non-water-absorbing, and easily die-cut as a pad; Opencell polyurethane foam with a sealed or coated surface - more cushioning, if water uptake is controlled; Neoprene or neoprene-laminated fabric - slightly compressible, good grip, nice feel; EPDM rubber - good hot-water and detergent resistance for a friction pad; Nitrile or styrene-butadiene (SBR) rubber - economical non-slip pad for the flange interior; Cork or cork-rubber composite - compressible, high friction, more “eco” look; Over-molded soft touch layer on a rigid plastic insert (e.g., PP or ABS core with TPE or silicone skin); Textile or webbing pad with silicone dots or stripes printed on the surface for grip and rim protection; Gel insert (silicone gel or Pll gel encapsulated in a thin film) for extra conformity to irregular rims; Microcellular urethane sheet - resilient, slow-recovery pad that can accommodate repeated clipping forces; and / or a replaceable adhesive foam tape pad - thin, peel-and-stick liner applied inside flange 501 for aftermarket adjustment.

[0121] In some embodiments, the clip can be a dual slot-end clip. In an example, FIG. 5D illustrates a plan or top view of a dual slot-end clip (306) configured to cooperate with looped strap segments on a sling corner. The dual slot-end clip (306) includes slots on ends (503a, 503b) formed at opposite sides of the clip body. Each slot on an end (503a, 503b) defines a corresponding re-entrant opening, shown as a first slot end (407a) and a second slot end (407b), through which individual fabric loops can be threaded.

[0122] In some embodiments, a strip attached to the sling forms a series of loops along its length, such as adjacent loops analogous to the inner loops described elsewhere. The dual slot-end clip (306) is installed by passing one loop through the first slot end (407a) and an adjacent loop through the second slot end (407b), so that the two loops are captured in the slots on ends (503a, 503b). When the loops are tensioned, the dual slot-end clip (306) is held at a defined position along the strip and is thereby prevented from separating from the sling during normal use.Docket No. 406682-555001 WO PCT Patent Application

[0123] According to some aspects, adjustment is achieved by repositioning the dual slot-end clip (306) along the series of loops rather than by moving a loop in and out of a single open slot. To change the elevation of the sling corner, the user releases the loops from the first and second slot ends (407a, 407b), selects a different pair of loops on the strip, and re-engages the dual slot-end clip (306) by threading the new loops into the slots on ends (503a, 503b). Moving the dual slot-end clip (306) outward or inward along the strip in this manner changes the effective span between the sling corner and the tub rim, raising or lowering the foot end of the sling while still keeping the clip captive on the fabric. According to some aspects in contrast, although not shown, the two slotted ends in FIG. 5D can be replaced by two closed ends, without the 503a and without the 503b, to provide a dual closed-end clip that will work for repositioning outward / inward on the fabric strip’s loops to raise and lower the foot end of the sling.

[0124] In another example, FIG. 6 illustrates a traditional clip sling assembly used with an infant bathtub having a basin (102) and a surrounding rim of tub (111 ). A sling (710) extends across the basin (102) between a head end of sling (705) and a bottom end of sling (715). The sling (710) is supported at its four corners by traditional clip (730) components that releasably engage the rim of tub (111 ). An optional tub backrest for a child’s upright seating position (701 ) is shown positioned within the basin (102), which can be adjacent the bottom end of sling (715), which in some embodiments, can be providing a two-position design to be used after a child has graduated from the sling and the sling has been removed from the tub.

[0125] In FIG. 6, for another example, the combination of the enveloping fabric around the head end of the tub with the multi position clips at the foot is not necessary. The head end of the sling would also work with traditional clips in this example.

[0126] According to some aspects, the head end of sling (705) is attached to the rim of tub (111 ) by a head strap (720) extending from the head-end corners of the sling (710) to respective traditional clip (730) elements. The head strap (720) may be formed of webbing or another flexible material and may include length adjustment hardware so that the head end of sling (705) can be tensioned to a desired height and recline angle relative to the basin (102). In this configuration, no enveloping flap is required at theDocket No. 406682-555001 WO PCT Patent Application head end; support is provided solely by the head strap (720) and the traditional clip (730) couplings to the rim of tub (111 ).

[0127] At the bottom end of sling (715), a foot strap (725) extends from each lower corner of the sling (710) to another traditional clip (730) on the rim of tub (111 ). The foot strap (725) may similarly include adjustment features to set the depth of the sling (710) within the basin (102). This traditional four-clip arrangement demonstrates that a sling (710) can be carried entirely by strap-and-clip connections at both the head and foot ends and further illustrates that the adjustable clip systems disclosed elsewhere may be used at one or both ends while remaining compatible with conventional strap-based attachments. In some embodiments, the purpose of the fabric strip passing through the closed slot is so that the clip does not separate from the sling to be lost. In an example, the adjustable nature would also work if the clip had two slotted ends (FIG. 5D) and it was repositioned outward / inward on the fabric strip’s loops to raise and lower the foot end of the sling. This example can reposition the clip on the fabric instead of repositioning the fabric on the clip. Although not shown, the two slotted ends in FIG. 5D can be replaced by two closed ends, without 503a and without 503b, to provide a dual closed-end clip that will work for repositioning outward / inward on the fabric strip’s loops to raise and lower the foot end of the sling.

[0128] In a non-limiting example discussion, one family of embodiments uses inner / outer loops 402 / 404 and open / closed slots 403 / 405 for the two-position height adjustment (e.g., FIGs. 4A-4B, FIGs. 5A-5C). In another example, another family of embodiments, uses loop of fabric 420, gathered fabric 500, released loop 507, secondary mounting location 508 (e.g., FIGS. 4C-4G). The families of embodiments are alternatives, and / or can be used together, the 420 / 507 can be in addition to or instead of the strap loops 402 / 404. In some embodiments the newborn contour 150 is produced by the fabric-gathering loop 420 / 507 instead of, or in addition to, the inner / outer loop geometry of FIGs. 4A and 4B. In these examples, the different families of embodiments can occur on opposite comers and / or on the same corner.

[0129] Further as described above and shown in the associated drawings, the present invention can comprise a sling for an infant bathtub. While particular embodiments have been described, it will be understood, however, that any inventionDocket No. 406682-555001 WO PCT Patent Application appertaining to the apparatus / system / method described is not limited thereto, since modifications may be made by those skilled in the art, particularly in light of the foregoing teachings. It is, therefore, contemplated by the appended claims to cover any such modifications that incorporate those features or those improvements that embody the spirit and scope of the invention.

[0130] In some embodiments, a sling is disclosed for an infant bathtub, the bathtub including a rim, the sling comprising: a top side for cradling an infant; a bottom side comprising: a first end with a flap for enclosing a portion of one end of the rim; a second end with opposite comers, each of the corners having a strip attached thereto such that an inner and an outer loop are formed and each of the corners having a clip attached to the strip wherein the clip is configured with a closed slot at a first end of the clip for receiving the outer loop, an open slot at a second end of the clip for removably receiving the inner loop, and a flange for engaging opposite sides of the rim. According to some aspect, the sling at least partially comprises a porous fabric.

[0131] In some embodiments, a sling (100) is configured to be used with an infant bathtub having a basin (102) and a surrounding rim (111 ). The sling (100) includes a sling body with a top side configured to cradle a newborn or infant and a bottom side (301 ) that carries attachment elements. As shown schematically in FIGs. 1A-2B, the sling (100) spans across the basin (102) while being supported along the rim (111 ) so as to define an elevated support surface. A first configuration corresponds to a loosened or slack contour (155) suitable for larger or more developmentally advanced infants, and a second configuration corresponds to a taut or newborn contour (150) that is higher for a newborn.

[0132] Stepping back to discuss the big picture; in some embodiments, the sling body includes a head end and a foot end. The head end is secured to the rim (111 ) by a flap (307) that extends across substantially the entire width of the sling body, as illustrated in FIGs. 1A, 1 B, and 3B. The flap (307) is configured to wrap over and optionally under the rim (111 ), enclosing a portion of the rim to form a frictional or pocket-like engagement that supports the head end of the sling (100) without clips or rigid hardware in the head region. Loads transmitted from a newborn’s head and upper torso are thereby distributed along a relatively broad segment of the rim (111 ).Docket No. 406682-555001 WO PCT Patent Application

[0133] The foot end of the sling (100) is adjustable and is anchored by a pair of corner assemblies. As shown in FIG. 3A, opposite corners of the second end of the sling (309a, 309b) each carry a strip (303a, 303b) attached to the bottom side (301 ). Each strip (303a, 303b) is folded and stitched to form one or more loops, including at least an inner loop (402) and an outer loop (404). A clip (305a, 305b) is attached to each strip (303a, 303b). The clips (305a, 305b) are generally identical and symmetrically arranged so that the sling (100) can be assembled without distinguishing between left and right hardware.

[0134] FIGs. 4A, 4B and 5A-5C illustrate representative clip geometry. In some embodiments, each clip (305) comprises a body with at least one closed slot and an open slot (403). At a first end of the clip (305), a closed slot region (405) may be subdivided into first and second closed slots (405a, 405b) through which the outer loop (404) is routed. Passing the outer loop (404) through one or both closed slots (405a, 405b) creates a permanent or semi-permanent connection between the strip (303) and the clip (305). References to a “closed slot (405)” may thus denote a single closed slot or a pair of closed slots (405a, 405b) that cooperate to capture the outer loop (404). At an opposite end of the clip (305), the open slot (403) is configured to selectively receive the inner loop (402). The open slot (403) preferably has a restricted entrance that allows the inner loop (402) to be pushed or pulled into the slot while resisting accidental release under expected service loads.

[0135] A hooked flange (501 ) extends from the clip body and is configured to engage opposite sides of the rim (111 ), as seen most clearly in FIG. 5C. The flange (501 ) may define a generally C-shaped channel sized to receive rims within a predetermined thickness range. In some embodiments, an optional insert pad (600) is provided within the flange (501 ). The insert pad (600) may be formed of an elastomer, foam, or composite material configured to conform to variations in rim thickness, increase friction, and protect the rim surface. By appropriate choice of flange geometry and pad material, the same clip (305) can be used on a variety of generic tub rims (111 ) without requiring molded receivers, holes, or dedicated mounting bosses.

[0136] Operation of the inner and outer loops can be understood with reference to FIGs. 1A, 1B, 2A, and 2B. In the raised newborn contour (150), the inner loops (402) atDocket No. 406682-555001 WO PCT Patent Application both foot-end corners are engaged in the respective open slots (403) of the clips (305a, 305b). Engagement of the inner loops (402) shortens the effective length of the strips (303a, 303b) between the comer regions (309a, 309b) and the clip bodies, thereby tightening the sling fabric at the foot end. Combined with head-end support from the flap (307), this adjustment suspends a central infant-support region higher above the basin (102) and produces a controlled recline angle suitable for a newborn. In the lowered infant sling position (155), the inner loops (402) are released from the open slots (403) while the outer loops (404) remain in the closed slots (405). The effective length of the strips (303a, 303b) increases, allowing the sling (100) to sag deeper into the basin (102) and to adopt a more relaxed contour appropriate for an older infant.

[0137] In further embodiments, a strip (303) forms three or more loops, including an outer loop (404) and multiple inner loops (402a, 402b, 402c). A single clip (305) with the same closed-slot and open-slot architecture can then provide three or more discrete support positions by selectively engaging different inner loops in the open slot (403). Adjacent loops may be spaced along the strip (303) at substantially equal increments so that height and angle changes occur in predictable steps. Visual indicators on the strip (303) or clip (305) may associate particular loops with recommended infant stages or weight ranges.

[0138] An alternative or complementary adjustment family is provided by a fabricgathering loop and secondary mounting location, as shown in FIGs. 4C-4G. In these embodiments, a loop of fabric (engaged loop 420) at an edge of the sling passes under or around the rim (111 ) and is engageable with a secondary mounting location (508) on a rear surface of the clip (305). When the loop of fabric is engaged with the secondary mounting location (508), the edge fabric is drawn toward the clip (305) and a band of gathered fabric (500) forms along the sling edge, as illustrated in FIGs. 4C-4E. The gathered fabric (500) shortens the edge path and creates a hammock-like newborn contour (150) in which side edge regions are higher than a central region.

[0139] When the loop of fabric is disengaged from the secondary mounting location (508), the same loop is referenced as a released loop of fabric (same loop in the release state 507) and the associated edge fabric is referenced as released fabric (505), as shown in FIGs. 4F and 4G. In this state, the previously gathered material isDocket No. 406682-555001 WO PCT Patent Application redistributed along the edge, lengthening the sling perimeter and allowing the sling to assume the lowered infant sling position (155). For clarity, the terms loop of fabric (engaged loop 420) and released loop of fabric (same loop in the release state 507) describe the same physical looped fabric element in two different engagement states relative to the secondary mounting location (508).

[0140] The loop-and-slot adjustment mechanism and the fabric-gathering mechanism may be implemented as alternatives or in combination. In some embodiments, only the inner / outer loop geometry (402, 404, 403, 405) is provided, and contour changes are achieved solely by engaging or releasing the inner loop (402). In other embodiments, only the fabric-gathering loop (420, 507) and secondary mounting location (508) are used to switch between gathered and released edge conditions. In yet further embodiments, both mechanisms are present on the same corner or on different corners. For example, a sling (100) may employ inner / outer loops on both footend corners to set a primary height level, while fabric-gathering loops on one or more edges fine-tune lateral cradle depth and anti-rolling characteristics. All such combinations are intended to be technically sensible variations of the same underlying teachings.

[0141] Through these arrangements, the sling (100) provides a family of newborn and infant support configurations that are compatible with generic tubs, allow straightforward caregiver installation and visual inspection, and maintain stable support contours under expected loading while keeping rigid hardware away from the newborn head region.

[0276] Exemplary Problem Statement: Newborn and infant bathing commonly occurs in compact household tubs or basins that were originally optimized for older babies or toddlers. Known infant bath tubs and sling products often provide only a single fixed contour, limited adjustability, or reliance on rigid shells. As a result, newborns with minimal head and trunk control may slide, rotate, or slump toward deeper water, raising drowning risk even at shallow depths. Existing supports can further present hard edges or exposed hardware near the head region, which is undesirable from both a safety and comfort perspective.

[0277] According to some aspects, safe newborn bathing would benefit from a support surface that remains elevated above the basin floor, maintains a stable recline angle within a physiologically appropriate range, and reduces tendencies toward rolling or downward migration along the support. In this example, attention is focused on scenarios in which a caregiver uses a small plastic tub within a sink or bathtub, where water depth, tub geometry, and caregiver reach may all vary substantially. Many currently available products assume a specific tub shape, incorporate fixed molded receivers, or require substantial assembly, which can increase mis-installation risk and limit compatibility with generic tubs.

[0278] In some embodiments, a newborn support system should permit rapid visual confirmation of proper setup, provide predictable support behavior under load, and allow adaptation as infant size and developmental stage change, without complicating use or cleaning. According to some aspects, a need remains for solutions that integrate fabricbased or mesh-based comfort with secure attachment to a rim or other structural feature, while avoiding additional protruding structures in the vicinity of the newborn’sDocket No. 406682-555001 WO PCT Patent Application head, and while supporting straightforward compliance with evolving child-safety guidance and consumer expectations.

[0279] Example Solution Overview: In some embodiments, the described technology provides a sling (100) that converts a generic infant or toddler bathtub (111 ) into a newborn-appropriate support without requiring molded receivers or dedicated hardware on the tub. A flexible sling body spans a basin (102) and is anchored at a head end by a flap (307) that wraps over the rim (111 ), distributing load along a broad region while keeping rigid components away from the newborn head zone. At the foot end, opposite comers (309a, 309b) carry strips (303a, 303b) that form inner and outer loops (402, 404) cooperatively engaged with clips (305a, 305b).

[0280] According to some aspects, each clip (305) incorporates closed slot regions (405a, 405b) that permanently capture the outer loop (404) and an open slot (403) that selectively receives the inner loop (402). When the inner loop (402) is engaged, the sling (100) assumes a raised newborn contour (150) that suspends the mesh top side above the basin floor to limit water depth around the infant and to maintain a stable recline angle. When the inner loop (402) is released from the open slot (403), the sling (100) transitions to a lowered infant sling position (155) suitable for larger or more developmentally advanced infants, without detaching the clips (305) from the rim (111 ).

[0281] In this example, the flange (501 ) of each clip (305) hooks over opposite sides of the rim (111 ) so that the system can latch onto a wide range of rim profiles found in compact plastic tubs or sink-supported basins. A porous or mesh top side promotes rapid drainage and breathability while edge bindings and rounded clip geometries minimize snagging and hard contact points. The resulting assembly aims to provide caregivers with an intuitive, visually inspectable setup that offers distinct newborn and infant positions, supports compliance with applicable bathing-aid safety guidance, and preserves straightforward cleaning and storage routines between uses.

[0282] In further aspects, kits of parts and assembly methods allow users to select particular combinations of sling bodies (100), mesh or fabric constructions, clip geometries (305), loop configurations (402, 404, 507), flap arrangements (307), attachment locations on a rim (111 ), and newborn or infant support contours (150, 155) to suit different bathtub shapes, installation environments, infant sizes, and caregiverDocket No. 406682-555001 WO PCT Patent Application preferences. According to some aspects, such kits provide a flexible and upgradable approach to the bathing-support problems described herein.

PROPHETIC METHODS OF TESTING AND / OR SAFETY TESTS

[0292] The devices and methods disclosed herein are put to a variety of internal safety tests and then additional tests based upon several countries’ regulations. TheseDocket No. 406682-555001 WO PCT Patent Application examples are illustrated in the tests listed below which begin by describing the example devices for the tests and then develop into the testing methods.

[0293] In this example, devices and methods disclosed herein are evaluated using safety test protocols aligned with requirements from multiple jurisdictions. The example is prophetic and is provided to illustrate representative configurations of sling assemblies and corresponding test procedures that may be used to demonstrate compliance with infant bathing product safety expectations.

[0294] In some embodiments, the example device comprises an infant bathtub having a basin (102) and a rim (111 ), together with a sling (100) that includes a mesh or porous top side, a bottom side (301 ), a head-end flap (307), and corner-mounted clips (305a, 305b) with loop arrangements (402, 404, 507, 508) configured as described above. The sling (100) is installed in a newborn configuration (150) and in a lowered infant configuration (155), and each configuration is evaluated separately. The bathtub may be placed within a sink or adult bathtub, or supported on a stable surface, depending on the test being simulated.

[0295] According to some aspects, the prophetic tests include static load and structural integrity evaluations in which a test mass representative of a newborn or infant is positioned on the sling (100) while forces are applied in downward, lateral, and rotational directions. Deflection of the sling (100), retention of the clips (305a, 305b) on the rim (111 ), and maintenance of the sling contour relative to the basin (102) are measured. Additional tests address tipping and stability, in which off-center loading and simulated caregiver interactions are used to determine whether the assembled bathtub and sling tend to tilt or rock in a manner that could increase submersion risk.

[0296] In further embodiments, the prophetic procedures include water-filling tests in which the basin (102) is incrementally filled while the sling (100) supports a test dummy. Water level, submersion depth, and the vertical location of a head region relative to the rim (111 ) and to the sling surface are recorded. Entrapment and pinch-point inspections are carried out around clips (305), loops (402, 404, 507), and edges of the sling (100). Durability tests may also be included, such as repeated installation and removal cycles, laundering cycles, and exposure to temperature variations, to assess long-term performance of the sling fabric, stitching, and hardware..Docket No. 406682-555001 WO PCT Patent Application
