Description

TECHNICAL FIELD

[0001] The present disclosure relates to a dining chair, in particular, to a dining chair provided with a back cushion. BACKGROUND

[0002] Dining chairs provide convenience for children aged from 6 months to 3 years old when they have meals. However, due to the large difference in the size of children, traditional children's dining chairs are often designed to be fixed in size, which leads to a problem: for children with smaller body size, the extra space inside the seat is large, and there is a gap between the child's body and the backrest of the seat. This gap makes the backrest of the seat unable to provide sufficient support for the child, causing the child to be unstable in the seat and easily tilt or even fall, which not only poses a hidden danger to the safety of the child, but also causes additional trouble to the parents and caregivers.

[0167] In addition, relational terms such as "first" and "second," and the like can be used solely to distinguish one entity or element from another entity or element without necessarily requiring or implying any actual relationship or order between or among the entities or elements. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure.

[0168] The present disclosure will be described in detail with reference to the accompanying drawings.

[0169] Figure 1A dining chair 10 with accessories of the present disclosure is schematically depicted. The dining chair 10 includes a seat 20, a base 30, a tray 40, a seat pad 50, and other accessories such as a back cushion 60, a footrest 90, and a protector 70. The seat 20 includes a seat portion 210 to carry a child's hips and / or thighs, a backrest portion 220 extending upwardly from a rear end of the seat portion 210 to rest against a child's back, and a legrest portion 230 extending downwardly from a front end of the seat portion 210 to rest against a child's lower leg. The base 30 is located below the seat 20 and supports the seat 20, and is movably connected with the seat 20 such that the seat 20 is adjustable in height relative to the base 30. The tray 40 is detachably connected with the seat 20 and is located in front of the backrest portion 220 and above the seat portion 210 of the seat 20 to carry food for a child to eat. The seat pad 50 is detachably provided on the seat 20, and includes a seat pad 510 located above the seat portion 210, a backrest pad 520 extending upwardly from a rear end of the seat pad 510 to rest against a child's back, and a legrest pad 530 extending downwardly from a front end of the seat pad 510 to rest against a child's lower leg. That is, the seat pad 510, the backrest pad 520, and the legrest pad 530 are connected with each other, and the seat pad 510 is located above the seat portion 210, the backrest pad 520 is located in front of the backrest portion 220, and the legrest pad 530 is located in front of the legrest portion 230, so that a child sitting on the seat 20 does not directly contact the seat 20 but directly contacts the seat pad 50 covering the surface of the seat 20 to improve the comfort of the child sitting on the seat 20. The footrest 90 is attached to the legrest portion 230 of the seat 20 and is located below the legrest pad 530 of the seat pad 50 to provide support for a child's feet sitting on the seat 20. The protector 70 is detachably connected with the backrest portion 220 and the seat portion 210 to define a sitting space for a child sitting on the seat 20, to limit the child from getting out of the sitting space, and the protector 70 is disposed below the tray 40 and supports the tray 40. The back cushion 60 is detachably provided on the backrest pad 520 of the seat pad 50, and when the back cushion 60 is mounted on the backrest pad 520, the gap between the backrest pad 520 and the tray 40 is reduced to provide support for the back of a child with a smaller body size, and when the back cushion 60 is detached from the backrest pad 520, the backrest pad 520 can provide support for the back of a child with a larger body size, so that the dining chair 10 can be adapted for use by children of different body sizes.

[0170] In other embodiments, the seat 20 can only include the seat portion 210 and the backrest portion 220 extending upwardly from a rear end of the seat portion 210, without the legrest portion 230 and the footrest 90 provided on the legrest portion 230, and correspondingly, the seat pad 50 can only include the seat pad 510 located above the seat portion 210 and the backrest pad 520 located in front of the backrest portion 220, without the legrest pad 530. Other structures are consistent with the above embodiments and will not be described here.

[0171] Below, refer to Figure 2 The connection relationships between the various components of the dining chair disclosed herein are described in detail.

[0172] exist Figure 2 In the middle, the base 30 is configured to support the floor, and includes two inverted U-shaped members 310 and 320 spaced apart in the left-right direction. Each inverted U-shaped member 310 and 320 includes front support legs 311 and 321 and rear support legs 312 and 322 spaced apart in the front-back direction (see...). Figure 3 Each inverted U-shaped member 310, 320 has front and rear support legs 311, 312, 321, 322 that are not parallel, and the angle between the top of each inverted U-shaped member 310, 320 and the corresponding front support leg 311, 312, and rear support leg 321, 322 is greater than 90 degrees. The base 30 also includes a transverse member 330 connecting the two inverted U-shaped members 310, 320. Specifically, the transverse member 330 connects the two front support legs 311, 321. The transverse member 330 may be constructed from a folded sheet steel assembly with a polypropylene injection-molded cap. Two T-shaped profile members 340, 350, which may be made of, for example, POM or nylon, are fixed to the front surface of the transverse member 330.

[0173] The back of the leg rest 230 of the seat 20 is provided with two aluminum extrusions (not shown) that mate with two T-shaped profiles 340 and 350. When the seat 20 is combined with the base 30, the two aluminum extrusions slide on the two T-shaped profiles 340 and 350 of the base 30, allowing the seat 20 to move upright relative to the base 30 in front of the front support legs 311 and 321 along the extending direction of the T-shaped profiles 340 and 350 for height adjustment. When the seat 20 reaches its lockable position relative to the base 30, a locking mechanism on the T-shaped profile locks it in that locked position.

[0174] To optimize logistics efficiency and reduce warehousing costs, the dining chair 10 disclosed herein is designed with minimizing packaging volume in mind. The seat 20 and base 30 are cleverly designed as two independent modules, with the seat 20 nested within the base 30, thereby significantly reducing the space required for packaging.

[0175] To more clearly describe the position and connection between the seat 20 and the seat cushion 50, Figure 3 Remove Figure 1 Other accessories in the dining chair, such as the plate 40, the protective piece 70, and the cushion 60.

[0176] See Figure 3As previously described, the seat 20 includes a seat portion 210, a backrest portion 220, and a leg rest portion 230. The seat portion 210 has a seat portion through-hole 211 at its front center for connection to the protective member 70. Here, "front" refers to the side away from the backrest portion 220 relative to it, and this front side connects to the upper side of the leg rest portion 230 extending downwards from the seat portion 210. The backrest portion 220 has backrest portion through-holes 221 on its left and right sides for connection to the protective member 70. The leg rest portion 230 engages with a footrest device 90 on its surface that contacts the child's lower leg, thereby connecting the footrest device 90 to the leg rest portion 230 of the seat 20. The seat 20 can be made of various materials, such as wood or plastics like polypropylene, and has a certain rigidity to support the child sitting in it.

[0177] See Figure 3 As previously described, the seat cushion 50 is detachably mounted on the seat 20. The seat cushion 50 is shaped to match the seat 20 and has a seat cushion 510, a backrest cushion 520, and a leg rest cushion 530 corresponding to the seat portion 210, backrest portion 220, and leg rest portion 230 of the seat 20. The seat cushion 510 is located above the seat portion 210 and below the tray 40. The backrest cushion 520 is located in front of the backrest portion 220 in the fore-and-aft direction, and the leg rest cushion 530 is located in front of the leg rest portion 230 in the fore-and-aft direction. A seat cushion through-hole 511 is provided at the center of the front side of the seat cushion 510, corresponding to the seat portion through-hole 211. This seat cushion through-hole 511 overlaps with the aforementioned seat portion through-hole 211 to allow the protective member 70 to pass through and connect with the seat portion through-hole 211. The backrest cushion 520 of the seat cushion 50 also has lateral openings 521 on its left and right sides, corresponding to the positions of the aforementioned backrest through holes 221, for the protective member 70 to pass through and connect with the backrest through holes 211. Based on the above description, since the protective member 70 is connected to the seat through holes 211 of the seat portion 210 and the backrest through holes 221 of the backrest portion 220, the protective member 70 is installed and positioned on the seat 20. The installation and positioning between the protective member 70 and the seat 20 requires passing through the seat cushion 50. Because the seat cushion 50 is connected to the protective member 70, it is indirectly positioned on the seat 20, effectively preventing the seat cushion 50 from shifting relative to the seat 20.

[0178] It is understandable that the seat cushion 510, backrest cushion 520 and leg cushion 530 of the seat cushion 50 can be molded as one piece or can be manufactured separately and then assembled.

[0179] The seat cushion 50 can be made of materials such as PU foam, which can prevent children from directly contacting the seat surface and provide children with a more comfortable riding experience. In this case, the seat cushion 50 only includes the seat cushion 510, the backrest cushion 520 and the leg cushion 530, and the three of them are made of the same PU foam.

[0180] Considering the cleaning needs of the seat cushion 50, the seat cushion 50 may also include a removable cover, which is fitted over the seat cushion 510, backrest cushion 520, and legrest cushion 530, so that it can be quickly removed for washing when needed, ensuring the hygiene of the seat cushion 50. That is, the seat cushion 50 at this time includes a cover and a cushion core composed of the seat cushion 510, backrest cushion 520, and legrest cushion 530.

[0181] like Figures 1-2 As shown, the protective member 70 includes a U-shaped main body 700, a cross member 710 extending from the U-shaped main body 700, and a baffle 730 extending from the U-shaped main body 700.

[0182] Both ends of the U-shaped main body 700 are provided with protrusions 720 that bend in the same direction for engaging with the backrest through holes 221. When the U-shaped main body 700 needs to be installed, the two ends can be inserted into the two backrest through holes 221 on both sides of the backrest 220 of the seat 20 through the lateral openings 521 on both sides of the backrest 50 of the seat cushion 50. By applying a force to the U-shaped main body 700 in the same direction as the recess of the slot (not shown) in the backrest through hole 221, the protrusions 720 will engage tightly with the slot, so that the U-shaped main body 700 is positioned in front of the backrest 220 and above the seat 210. When the U-shaped main body 700 needs to be removed, only a force opposite to the recess of the slot needs to be applied to release the protrusions 720 from the slot. As described above, since the side opening 521 of the backrest cushion 520 and the backrest through hole 221 of the backrest part 220 are matched in position and size and are both limited by the two ends of the U-shaped main body part 700, this ensures that the displacement of the backrest cushion 520 of the seat cushion 50 in the up-down and left-right directions is restricted, thereby ensuring that the seat cushion 50 will not be displaced relative to the seat 20 and the protective member 70.

[0183] The crotch component 710 is integrally formed into the U-shaped main body 700, specifically extending downward from the center of the front side of the U-shaped main body 700 and connecting to the seat portion 210 to position the U-shaped main body 700 above the seat portion 210. Specifically, the crotch component 710 is provided with a crotch latch 7101. When the crotch component 710 needs to be installed, the crotch latch 7101 of the crotch component 710 is pressed through the seat cushion through hole 511 of the seat cushion 50 and into the seat portion through hole 211 in the seat portion 210, thereby locking the crotch component 710 onto the seat portion 210 and positioning the U-shaped main body 700 above the seat portion 210. If the crotch component 710 needs to be removed, simply push the flexible portion (not shown) of the crotch component 710 to release the crotch latch 7101, thereby releasing the crotch component 710 from the seat portion 210. As described above, since the hip latch 7101 of the hip member 710 passes through the seat cushion through hole 511 of the seat cushion 20 and is pressed into the seat part through hole 211 in the seat part 210, the seat cushion 20 is restricted by the hip member 710 in the left-right and front-back directions, further ensuring that the seat cushion 50 will not be displaced relative to the seat 20 and the protective member 70.

[0184] Furthermore, to further enhance children's riding safety and prevent them from accidentally slipping out of the gap between the U-shaped main body 700 and the seat 20, the protective component 70 has baffles 730 extending towards the seat 510 on both the left and right sides of the U-shaped main body 700. Thus, when the protective component 70 is installed on the seat 20, the protective component 70, together with the backrest cushion 520 and seat cushion 510 of the seat cushion 50, form a relatively enclosed riding space, providing a relatively safe dining environment for children.

[0185] like Figure 2 As shown, the plate 40 is mounted above and supported by the protective member 70. The plate 40 includes a plate portion 410 and two protruding ribs 420 extending rearward from the left and right sides of the plate portion 410 and spaced apart from each other. Each of the two protruding ribs 420 of the plate 40 is provided with a plate latch 430, which is located on the lower surface of the protruding rib 420 and is used to engage with the two side arms of the U-shaped main body portion 700 of the protective member 70. When the plate 40 is installed, the two protruding ribs 420 are placed on the two side arms of the U-shaped main body portion 700 and engaged with the two side arms of the U-shaped main body portion 700 through the plate latches 430, ensuring that the plate is stably supported on the protective member 70 during use. The two protruding ribs 420 are positioned above the two side arms of the U-shaped main body portion 700, and the plate portion 410 is positioned above the horizontal arm between the two side arms of the U-shaped main body portion 700. When it is necessary to remove the plate 40, simply bend the plate latch 430 of the plate 40 outwards to pull the plate 40 off the seat 20 and remove it. The plate 40 can be manufactured, for example, by injection molding from polypropylene.

[0186] The dining chair design disclosed herein takes into full account the different needs of children during their growth process and provides three flexible usage modes to adapt to children of different ages.

[0187] Mode 1: Infant and Toddler Use Mode. For young and small children, the high chair 10 is equipped with a complete set of accessories, including a tray 40, a protective element 70, a backrest 60, a footrest 90, and a safety belt (not shown). The tray 40 is attached to the protective element 70 via a tray latch 430. The protective element 70 is connected to the backrest 220 of the seat 20 via protrusions 720 at both ends of the U-shaped main body 700, and to the seat 210 of the seat 20 via a hip latch 7101 of the hip member 710, thus ensuring a relatively enclosed seating space for young children in the seat 20. Furthermore, the soft seat cushion 50 provides extra comfort for very young children, the backrest 60 reduces the gap between the backrest 520 and the tray 410 to provide back support for young and small children, preventing them from becoming unstable, and the safety belt ensures their safety in the seat 20. For young and large children, the back cushion 60 can be removed from the back cushion 520 so that the back cushion 520 can support the back of the young and large child.

[0188] Mode Two: Growing Child Use Mode. As the child grows, the tray 40 and cushion 60 may no longer be needed, but the seat cushion 50, protective piece 70, footrest 90, and safety belt remain essential. In this mode, the tray 40 and cushion 60 can be removed, while the seat cushion 50, protective piece 70, and footrest 90 are retained. For larger children, the seat cushion 50 can also be removed. This adjustment allows the high chair to adapt to the child's growth while maintaining its functionality and safety.

[0189] Mode 3: Older Child Use Mode. For older children, the tray 40, cushion 60, protective piece 70, footrest 90, and seat belt may no longer be needed, but the seat cushion 50 can be retained. For larger older children, the seat cushion 50 can also be removed. In this mode, all these accessories can be removed, converting the high chair 10 into a regular seat.

[0190] like Figure 1 , Figure 5 and Figure 6As shown, the width of the cushion 60 is less than or equal to the width of the seat cushion 50, so that the cushion 60 can be properly placed on the seat cushion 50 and in close contact with the front surface of the backrest cushion 520. The cushion 60 includes a cushion body 610, which is located between the tray portion 410 and the backrest cushion 520 in the fore-aft direction. By setting the cushion 60, the distance between the inner edge 4101 of the tray portion 410 and the front surface of the cushion 60 is less than the distance between the inner edge 4101 of the tray portion 410 and the front surface of the backrest cushion 520, thereby reducing the internal space of the high chair 10 in the fore-aft direction. This improvement not only improves the seating comfort of young children, but also significantly enhances safety during meals. In this document, the inner edge 4101 of the tray refers to the edge of the tray portion 410 that is closest to the child sitting in the seat 20.

[0191] It is understood that the length of the backrest 60 is not particularly limited, as long as it can support the child's back. Preferably, the shape of the backrest 60 matches the shape of the backrest 520 of the seat cushion 50.

[0192] The thickness of the cushion body 610 of the cushion 60 can be 10-40mm, preferably 25mm.

[0193] The cushion body 610 of the backrest 60 can be made of PU foam, the same material as the backrest cushion 520 and seat cushion 510 mentioned above.

[0194] To ensure the comfort of children, the cushion 610 has an arc-shaped cross-section that protrudes towards the backrest cushion 520 to better surround the child's back, which is ergonomic.

[0195] The cushion 60 disclosed herein may be provided with an outer cover 80, such as Figure 4 As shown, the outer cover 80 includes a cover body 810 that covers the cushion body 610 and a connector 820 that is detachably connected to the backrest cushion 520 of the seat cushion 50. The front surface of the aforementioned backrest cushion 60 is the front surface of the outer cover 80.

[0196] The cover 810 may have a retrieval opening 811 for inserting or removing the pad 610 from the cover 80, so that the pad 610 can be removed from the cover 80 through the retrieval opening 811 for cleaning. The retrieval opening 811 may be located at the top, back, or bottom of the cover 80. Preferably, the retrieval opening 811 is located near the top of the cover 80 to prevent the pad 610 from falling out of the retrieval opening 811 due to gravity. Simultaneously, the retrieval opening 811 is located on the back of the cover 80 to prevent children from removing the pad 610 from the retrieval opening 811. It is understood that the area of ​​the retrieval opening 811 is smaller than the cross-sectional area of ​​the pad 610 to further prevent the pad 610 from falling out of the retrieval opening 811 of the cover 80.

[0197] To further prevent the pad 610 from accidentally falling out of the opening 811 of the cover 810, the cover 810 is provided with a third connector 8111 and a fourth connector 8112 connected to each other on both sides of the opening 811. In use, the third connector 8111 and the fourth connector 8112 can connect to each other to prevent the pad 610 from falling out of the opening 811; when it is necessary to remove the pad 610, the third connector 8111 and the fourth connector 8112 can separate to allow the pad 610 to be removed from the opening 811. The third connector 8111 and the fourth connector 8112 can be zippers, male and female buckles, hooks and holes, the rough side and hook side of Velcro, or buttons and buttonholes, etc. It is understandable that, for the sake of the aesthetics of the cushion 60, a cover can be provided on the opening 811 of the cover 810 to cover the exposed third connector 8111 and fourth connector 8112, and to further prevent children from accidentally disconnecting the originally interconnected third connector 8111 and fourth connector 8112.

[0198] In this embodiment, as Figure 4 As shown, the opening 811 is shaped like an envelope opening, that is, the cover 810 parts on both sides of the opening 811 are stacked on each other. A third connector 8111 is provided on one side, specifically a button, and a fourth connector 8112 is provided on the other side, specifically a snap hole, so as to take out the pad 610 when needed.

[0199] As previously described, the outer cover 80 is provided with a connector 820 for detachably connecting to the backrest cushion 520 of the seat cushion 50. The connector 820 of this disclosure can be implemented in various ways. Preferred embodiments of the connector are described in detail below with reference to the accompanying drawings.

[0200] Figure 5 An embodiment of the cushion 60 of this disclosure is schematically shown, wherein a strip-shaped member is provided. This strip-shaped member is the aforementioned connector 820. Figure 5 As shown, the two connecting ends of the strip are arranged opposite to each other and connected to the cover 810, preferably at the middle position of the two sides of the cover 810. The strip and the cover 810 form a closed loop for the backrest cushion 520 of the seat cushion 50 to be inserted. The area formed by the closed loop is slightly larger than the cross-sectional area of ​​the backrest cushion 520, that is, there is a gap between the strip, the cover 810 and the backrest cushion 520 so that it can be fitted onto the backrest cushion 520. It can be understood that the strip can be a relatively wide piece of fabric.

[0201] The aforementioned strip can be elastic, such as an elastic band. In this case, the area of ​​the closed loop formed by the strip and the cover 810 for the backrest 520 of the seat cushion 50 to be inserted can be smaller than the cross-sectional area of ​​the backrest 520 of the seat cushion 50. That is, there is almost no gap between the strip, the cover 810 and the backrest 520, and the strip is fitted onto the backrest 520 by means of the elastic force of the strip.

[0202] Figure 6 The illustration schematically shows an embodiment of the cushion 60 of this disclosure provided with two strips. The connector 820 consists of two strips, each having a connecting end 821 and a free end 822. Both connecting ends 821 of the two strips are connected to the cover 810, and the two free ends 822 of the two strips are interconnected, such that the two strips and the cover 810 form a closed loop for the backrest cushion 520 to be inserted. Figure 6 As shown, the two connecting ends 821 of the two strip-shaped pieces are arranged opposite to each other and connected to the cover 810, preferably at the middle position of the two sides of the cover 810. The free ends 822 of the two strip-shaped pieces are configured with a first connecting member 8221 and a second connecting member 8222 that are connected to each other. The first connecting member 8221 and the second connecting member 8222 can be a zipper, a male and female buckle, a hook and hole, the rough side and the hook side of Velcro, or a button and a buttonhole, etc., as long as it can connect the two free ends 822 to each other.

[0203] As mentioned above, when the connector 820 is a strip, it can be fixed to both sides of the outer cover 80 by sewing, preferably at 1 / 2 or 1 / 3 of the length of both sides.

[0204] It is understandable that when the connector 820 is a strip, multiple strips can be provided on the outer cover 80.

[0205] Figure 7 The illustration schematically shows an embodiment where a receiving space is provided on the top of the cushion 60 of this disclosure. A connector 820 is configured to enclose the receiving space with the cover 810. The connector 820 also has an opening 823 for the backrest cushion 520 to enter the receiving space, located below the receiving space, so as to be fitted onto the top of the backrest cushion 520 of the seat cushion 50. In this disclosure, in addition to connecting the cushion 60 to the backrest cushion 520, the connector 820 can also serve as a cover to conceal the access port 811 of the cover 80, preventing children from removing the cushion 610 from the access port 811 of the cover 80.

[0206] It is understood that connectors may also be provided on the seat cushion 50 of this disclosure. In order to strengthen the connection between the seat cushion 50 and the seat 20, connectors may also be provided on the seat cushion 510 and / or backrest cushion 520 and / or leg rest cushion 530 of the seat cushion 50.

[0207] As mentioned earlier, the connector 820 is specifically connected to the outer cover of the seat cushion 50. Compared to the method of connecting the connector 820 directly to the PU foam back cushion 520 of the seat cushion 50, the friction between the connector 820 and the outer cover allows the back cushion 60 to be stably connected to the seat cushion 50.

[0208] It should be noted that the backrest 60 of this disclosure can also be directly and detachably installed on the backrest 220 of the seat 20 to adapt to various dining chairs; that is, in this case, there is no backrest 520 of the seat cushion 50. Figure 5 and Figure 6 In the embodiment shown, the closed loop formed by the strip and the cover 810 can be fitted over the backrest 220 of the seat 20, such as... Figure 7 In the embodiment shown, the receiving space formed by the connector 820 and the cover 810 can accommodate the top of the backrest 220 of the seat 20 downwards, which can meet the needs of smaller children among the older children in the above-mentioned mode three.

[0209] The improved high chair 10 disclosed herein aims to provide adjustable interior space for children of different sizes and ages to meet their diverse needs as they grow. For younger or smaller children, guardians can add a backrest cushion 520 to the front of the backrest 520 of the seat 20, and place a cushion 60 between the backrest cushion 520 and the tray section 410. The cushion 60 is connected to the backrest cushion 520 of the seat 50 via a connector 820, indirectly connecting the cushion 60 to the backrest 220 of the seat 20. This creates a compact and supportive interior space between the backrest 220 and the tray section 410, ensuring the child's comfort and safety. Conversely, for older or larger children, guardians can choose to remove the cushion 60, thereby expanding the interior space of the high chair 10, allowing older children to also enjoy a spacious and comfortable seating experience. This improved design enhances the practicality of the high chair 10 and allows it to grow with children, adapting to their needs at different stages.

[0210] In actual use, the seat cushion core and the cover covering the core can easily shift relative to each other due to the movement of the infant sitting in it, which reduces the infant's comfort. To solve this problem, this disclosure provides a seat cushion with a positioning structure designed to achieve a close fit between the cover and the core.

[0211] The disclosed seat cushion 50 includes a cushion core 500, an outer cover 800 covering the cushion core 500, and a positioning structure 900 disposed between the cushion core 500 and the outer cover 800. The positioning structure 900 is configured to detachably connect the outer cover 800 to the cushion core 500 and ensure that the outer cover 800 can stably and tightly conform to the cushion core 500, thereby improving the riding experience for infants and toddlers.

[0212] In this embodiment, the directions "front," "rear," "left," "right," "up," and "down" are all defined relative to the seat cushion 50. Specifically, when an infant or toddler sits in the seat cushion 50, the surface for the infant or toddler to sit on is considered the front 501 (forward-facing) of the seat cushion 50, and the surface opposite to the front 501 is considered the back 502 (rear-facing) of the seat cushion 50. Directions perpendicular to the front-back direction on a horizontal plane are considered the left-right direction of the seat cushion 50; directions perpendicular to the left-right and front-back directions are the up-down directions of the seat cushion 50. Here, any one of the front-back, left-right, and up-down directions can be considered a first axis; directions intersecting the first axis are considered a second axis; and directions intersecting both the first and second axes are considered a third axis. Preferably, in... Figures 9 to 1 In the three embodiments, the first axis is the front-to-back direction, the second axis is the up-to-down direction, and the third axis is the left-to-right direction.

[0213] Reference Figure 9 and Figure 10 The figures show perspective views of the front 501 and back 502 of the seat cushion according to the present disclosure.

[0214] The disclosed seat cushion 50 provides a seating space for infants and toddlers. The seat cushion 50 includes a core 500 and an outer cover 800. The core 500 has a front 501 facing the seating space and a back 502 facing away from the seating space. The outer cover 800 covers the core 500 and has a first body 830 facing the front 501 and a second body 840 facing the back 502. The shape and size of the outer cover 800 are substantially adapted to the shape and size of the core 500.

[0215] Specifically, the outer casing 800 is constructed as a bag-like structure, with a first body 830 covering the front 501 of the padding core 500 and a second body 840 covering the back 502 of the padding core 500. Since the padding core 500 has a certain thickness, it also has a top and a bottom in the vertical direction and two sides in the horizontal direction. The top and bottom of the padding core 500 abut against the top and bottom of the outer casing 800, respectively, thereby restricting the displacement of the padding core 500 in the vertical direction of the outer casing 800; the two sides of the padding core 500 contact the two sides 831 of the outer casing 800, thereby restricting the displacement of the padding core 500 in the horizontal direction of the outer casing 800.

[0216] In practical applications, since the first cover 830 is in direct contact with the infant, to prevent displacement of the first cover 830 relative to the front 501 of the cushion core 500 due to the movement of the infant sitting in the seat cushion 50, this disclosure provides a positioning structure 900. This positioning structure 900 is disposed between the first cover 830 and the cushion core 500, aiming to ensure that the first cover 830 can stably and tightly cover the front 501 of the cushion core 500, thereby effectively preventing displacement between the cover 800 and the cushion core 500 when the infant sitting in the seat cushion 50 is moving.

[0217] exist Figure 9 In the illustrated embodiment, the cushion core 500 may include a seat cushion 510, a backrest cushion 520, and a leg rest cushion 530. As described above, the backrest cushion 520 extends upward from the rear end of the seat cushion 510, and the leg rest cushion 530 extends downward from the front end of the seat cushion 510. Therefore, the cushion core 500 is configured to be generally Z-shaped, but the shape of the cushion core 500 is not limited to this. The cushion core 500 may also include only the seat cushion 510 and the backrest cushion 520 extending upward from the rear end of the seat cushion 510, and the shape of the seat cushion 50 may be generally L-shaped. Correspondingly, the cover 800 may include a seat cover 801 covering the seat cushion 510, a backrest cover 802 covering the backrest cushion 520, and a leg rest cover 803 covering the leg rest cushion 530, with the backrest cover 802, seat cover 801, and leg rest cover 803 connected in sequence. For a cushion core 500 consisting only of a seat cushion 510 and a backrest cushion 520, the outer cover 800 may include a seat cover 801 covering the seat cushion 510 and a backrest cover 802 covering the backrest cushion 520. Preferably, the positioning structure 900 and the first sleeve 830 may be connected at the connection between the seat cover 801 and the backrest cover 802. Correspondingly, the positioning structure 900 and the cushion core 500 may be connected at the connection between the seat cushion 510 and the backrest cushion 520. More preferably, in addition to the aforementioned positioning structure 900, this disclosure may also provide another positioning structure (not shown), which is also provided between the cushion core 500 and the first sleeve 830, allowing the cushion core 500 and the first sleeve 830 to be detachably connected, and also used to prevent the outer cover 800 and the cushion core 500 from shifting towards each other due to the activities of infants and young children. The other positioning structure is connected to the first sleeve 830 at the connection between the seat cover 801 and the leg rest 803, and to the cushion core 500 at the connection between the seat cushion 520 and the leg rest 530. In this disclosure, the structure of the other positioning structure is the same as that of the positioning structure 900, except that the connection position with the cushion core 500 and the first sleeve 830 is different.

[0218] As described above, the seat cushion 510 is also provided with a seat cushion through hole 511 for the hip buckle 7101 to pass through the seat cushion 50 and connect with the seat part through hole 211 in the seat part 210; correspondingly, the seat cover 801 of the outer cover 800 is also provided with a seat cover through hole 834, and the cushion core 500 is also provided with a cushion core through hole (not shown). The seat cover through hole 834 and the cushion core through hole constitute the seat cushion through hole 511, that is, the hip buckle 7101 will pass through the seat cover through hole 834 and the cushion core through hole to connect with the seat part through hole 211 in the seat part 210. When the hip component 70 passes through the seat cushion through hole 511 and the hip buckle 7101 is pressed into the seat part through hole 211, the outer cover 800 and the cushion core 500 of the seat cushion 510 are restricted by the hip component 70 in the vertical direction and the horizontal direction, further preventing displacement between the first cover 830 and the front surface 501 of the cushion core 500.

[0219] To facilitate changing or washing the outer cover 800, this disclosure also provides an opening 844 on the outer cover 800. The opening 844 can be provided on at least one of the two sides 831 of the outer cover 800, or on the second body 840. Preferably, the opening 844 can be provided on the second body 840 near one of the sides 831. Preferably, the opening 844 can be provided to extend from the backrest cover 802 of the second body 840 to the seat cover 801; more preferably, the opening 844 can be provided to extend from the backrest cover 802 of the second body 840 to the leg rest cover 803. For an outer cover 800 consisting only of a seat cover 801 and a backrest cover 802, the opening can be provided to extend from the backrest cover 802 of the second body 840 to the seat cover 801. Because the opening 844 is relatively long, it allows users to easily remove or insert the pad 500 from the outer cover 800, making it convenient to replace or clean the outer cover 800. Furthermore, since the opening 844 extends through the connection point between the positioning structure 900 and the pad 500 and the first body 830, it also facilitates the user to connect the positioning structure 900 to the first body 830 and the pad 500 through the opening 844.

[0220] To prevent the cushion core 500 from accidentally falling out of the opening 844, this disclosure provides detachable connecting structures on both sides of the opening 844, such as zippers 845. However, this disclosure is not limited to this; it can also be mutually cooperating Velcro, male and female buckles, or straps, as long as they can close the opening 844 when the seat cushion 50 is in use.

[0221] To enhance the overall aesthetics and safety of the seat cushion 50, the seat cushion 50 of this disclosure further provides a cover portion 846 for concealing the detachable connection structure. In this embodiment, the cover portion 846 extends along the direction of the opening 844 and covers the opening 844. Preferably, the material of the cover portion 846 can be the same as the material of the outer cover 800. The cover portion 846 not only enhances the aesthetics of the seat cushion 50, but also effectively prevents the risk of the cushion core 500 coming off the outer cover 800 due to accidental pulling by infants during use. Preferably, a detachable connection structure, such as a zipper, Velcro, snap fasteners, or straps, can also be provided between the cover portion 846 and the outer cover 800.

[0222] Below, we will refer to Figures 11A-13B The positioning structure 900 of this disclosure is described in detail.

[0223] Figures 11A-11B It is a schematic representation of from Figure 10 The image shows a perspective view of the outer casing 800 after the pad core 500 has been removed, wherein the outer casing 800 is provided with a positioning structure 900. The positioning structure 900 includes a positioning element 910 and a positioning hole 920. The positioning element 910 is connected to the first housing 830, preferably to the inner side of the first housing 830, which contacts the front surface 501 of the pad core 500. The positioning hole 920 can penetrate the front surface 501 and the back surface 502 of the pad core 500 along a first axial direction (i.e., the front-to-back direction), and is thus a through hole penetrating the pad core 500. The positioning element 910 is correspondingly provided with the positioning hole 920 so that the positioning element 910 passes through the positioning hole 920 and is detachably connected to the back surface 502 of the pad core 500, thereby allowing the first housing 830 to fit tightly against the front surface 501 of the pad core 500.

[0224] In other embodiments, the positioning structure 900 can also be configured such that the positioning member 910 passes through the positioning hole 920 and is detachably connected to the second body 840 of the outer sleeve 800, thereby achieving a tight fit between the first body 830 and the front surface 501 of the padding core 500. Here, the positioning member 910, after passing through the positioning hole 920, can be connected to the second body 840 via a detachable connection structure such as Velcro, snap fasteners, or ties that connect with each other.

[0225] Furthermore, the positioning structure 900 is not limited to the above-mentioned matching method of positioning element 910 and positioning hole 920. It can also be a detachable connection structure such as Velcro, male and female buckles, or ties that are attached to each other between the first outer sleeve 830 of the outer sleeve 800 and the front face 501 of the padding core 500, so that the first body 830 and the front face 501 of the padding core 500 can be directly and detachably connected, thereby achieving a tight fit between the first body 830 and the front face 501 of the padding core 500.

[0226] like Figure 11A and Figure 11B As shown, the positioning member 910 may include a body portion 911 and a positioning portion 912 connected to each other. When the positioning structure 900 is connected to the outer sleeve 800 and the pad core 500, the body portion 911 is accommodated in the positioning hole 920 and connected to the first outer sleeve 830; the positioning portion 912 protrudes from the back surface 502 of the pad core 500 and is detachably connected to the back surface 502. Specifically, the body portion 911 extends along a first axial direction, and the positioning portion 912 extends in a plane intersecting the first axial direction and is detachably connected to the back surface 502. In order to achieve the detachable connection between the positioning portion 912 and the back surface 502, the positioning portion 912 must have a portion extending beyond the positioning hole 920 in the plane intersecting the first axial direction, so as to achieve the detachable connection with the back surface 502 through this portion.

[0227] In this embodiment, the main body 911 has a first connecting end 9111 and a second connecting end 9112. The first connecting end 9111 can be fixedly or detachably connected to the first sleeve 830, and preferably, it can be sewn to the first sleeve 830. Optionally, the first connecting end 9111 is connected to the connection between the seat cover 801 and the backrest cover 802 of the first sleeve 830. It can be understood that the first connecting end 9111 of the main body 911 can be flexibly set according to actual needs and is not limited to the position described above. The second connecting end 9112 can be movably or detachably connected to the positioning part 912, that is, the main body 911 can be movably or detachably connected to the positioning part 912. When the second connecting end 9112 is movably connected to the positioning part 912, the positioning part 912 can move relative to the main body 911, allowing the positioning part 912 to pass through the positioning hole 920 along the first axial direction together with the main body 911. After passing through the positioning hole 920, the positioning part 912 can be detachably connected to the back surface 502 on a plane intersecting the first axial direction. Optionally, the main body 911 and the positioning part 912 are pivotally connected. When the second connecting end 9112 and the positioning part 912 are detachably connected, after the main body 911 passes through the positioning hole 920 along the first axial direction, it can be detachably connected to the extended positioning part 912 on a plane intersecting the first axial direction.

[0228] Preferably, when the seat cushion 50 is also provided with another positioning structure, the first connecting end 9111 of the main body portion 911 of the other positioning structure can also be connected to the connection between the seat cover 801 and the leg rest 803 of the first body 830. The second connecting end 9112 can also be movably or detachably connected to the corresponding positioning portion 912, just like the positioning structure 900.

[0229] In this embodiment, the positioning part 912 is movably connected to the body part 911. Specifically, the body part 911 and the positioning part 912 are pivotally connected. When the positioning member 910 passes through the positioning hole 920 along the first axial direction, the positioning part 912 can pivot to at least partially overlap and fit with the body part 911. Preferably, the positioning part 912 and the body part 911 are parallel to each other and both extend along the first axial direction. At this time, the positioning part 912 is in the first position. After the positioning part 912 continues to extend out of the positioning hole 920, it is detachably connected to the back surface 502. The body part 911 is still accommodated in the positioning hole 920 and remains in the first axial direction, while the positioning part 912 extends out of the positioning hole 920 and extends beyond the positioning hole 920 on a plane intersecting with the first axial direction, thereby making the positioning part 912 detachably connected to the back surface 502 of the pad core 500. The extension direction of the positioning part 912 intersects with the extension direction of the body part 911. At this time, the positioning part 912 is in the second position. In other words, the positioning part 912 changes from a parallel state to an intersecting state with the main body part 911 as it moves from the first position to the second position.

[0230] As described above, the positioning part 912 is exposed on the back surface 502 of the padding core 500 and is detachably connected to the back surface 502. Specifically, the positioning part 912 can abut forward against the back surface 502 of the padding core 500 to be detachably connected to the back surface 502; or by providing a detachable connection structure such as Velcro, male and female buckles, or ties that can fit together between the positioning part 912 and the back surface 502 of the padding core 500, the positioning part 912 can be detachably connected to the back surface 502, thereby achieving the fit between the first body 830 of the outer cover 800 and the front surface 501 of the padding core 500.

[0231] The following describes in detail the implementation of the positioning part 912 and its connection relationship with the main body part 911 when the positioning part 912 abuts against the back surface 502 of the pad core 500.

[0232] It should be noted that when the positioning part 912 abuts against the back surface 502, on the plane intersecting the first axial direction, the positioning part 912 can extend beyond the positioning hole 920 in at least two different directions relative to the positioning hole 920 to abut against the back surface 502, ensuring that the positioning part 912 cannot easily dislodge from the positioning hole 920. Preferably, the hardness of the positioning part 912 needs to be greater than the hardness of the body part 911, so that the positioning part 912 cannot easily dislodge from the positioning hole 920. Preferably, on the second axial direction intersecting the first axial direction, the positioning part 912 extends beyond the positioning hole 920 in two opposite directions to abut against the back surface 502. Preferably, the second axial direction is the vertical direction.

[0233] It is understood that after the positioning part 912 passes through the positioning hole 920 and abuts against the back surface 502, the cross-section of the body part 911 can be located within or coincide with the projection plane of the positioning hole 920 on a plane perpendicular to the first axial direction, so as to smoothly pass through the positioning hole 920. Simultaneously, on a plane perpendicular to the second axial direction, the cross-section of the positioning part 912 can be located within or coincide with the projection plane of the positioning hole 920 on a plane perpendicular to the first axial direction, so that the positioning part 912 can smoothly pass through the positioning hole 920. Preferably, in the first axial direction, the length of the body part 911 can be equal to or slightly less than the depth of the positioning hole 920, so that the positioning part 912 can stably abut against the back surface 502 of the pad core 500.

[0234] In other embodiments, the positioning part 912 is detachably connected to the back surface 502. That is, after the positioning part 912 passes through the positioning hole 920 and protrudes from the back surface 502, the positioning part 912 and the back surface 502 can be detachably connected together by a detachable connection structure, such as Velcro that fits together, male and female buckles that fasten together, or straps that connect together. The positioning part 912 only needs to extend beyond the positioning hole 920 in at least one direction relative to the positioning hole 920 to be detachably connected to the back surface 502.

[0235] Below, we will refer to Figure 11B A detailed description is provided of an embodiment in which the hardness of the positioning part 912 is greater than the hardness of the body part 911 when the positioning part 912 abuts against the back surface 502 of the pad core 500.

[0236] In one embodiment, the body portion 911 may only include the first belt 914, and the positioning portion 912 may include the second belt 915 and a rigid plate 913. Both the first belt 914 and the second belt 915 have a certain degree of flexibility. Since the positioning portion 912 includes the rigid plate 913 in addition to the second belt 915, the hardness of the positioning portion 912 is greater than that of the body portion 911. Optionally, the rigid plate 913 may be made of PP or PE, etc. Optionally, the first belt 914 and the second belt 915 may be made of the same material. Optionally, the first belt 914 and the second belt 915 may be made of the same webbing or separately made of two webbings sewn together and connected.

[0237] The following will clearly describe how the first tape body 914 and the second tape body 915 covering the rigid plate 913 are formed when the first tape body 914 and the second tape body 915 are made of the same webbing. The first end of the webbing is connected to the first sleeve 801, and the second end of the webbing surrounds the entire rigid plate 913 along its length, and is connected to the middle of the webbing. This allows the positioning part 912, made of a portion of the webbing and the rigid plate 913, to pivot relative to the body part 911, made of another portion of the webbing, at the middle of the webbing, so that the positioning part 912 is movably connected to the body part 911. When the first tape body 914 and the second tape body 915 are made of two separate webbings, the first end of the webbing used to make the first tape body 914 is connected to the first sleeve 801, and both ends of the webbing used to make the second tape body 915 surround the entire rigid plate 913 along its length and are connected end-to-end to connect with the second end of the webbing used to make the first tape body 914. Similarly, the positioning part 912, which is made of the webbing that forms the second belt body 915 and the rigid plate 913, can pivot relative to the body part 911 made of the webbing that forms the first belt body 914 at the position where the webbing that forms the second belt body 915 is connected end to end, so that the positioning part 912 is movably connected to the body part 911.

[0238] In one embodiment, the body portion 911 may consist only of the first belt 914, and the positioning portion 912 may consist only of a rigid plate 913. The first belt 914 has a certain degree of flexibility, and the rigid plate 913 has a higher hardness than the first belt 914. Preferably, the rigid plate 913 may be made of PP or PE, etc. The rigid plate 913 can pivot relative to the first belt 914 at its connection point, that is, the positioning portion 912 is pivotally connected to the body portion 911.

[0239] In one embodiment, the body portion 911 may consist only of a first webbing 914, and the positioning portion 912 may consist only of a second webbing 915. The first webbing 914 and the second webbing 915 may be made of the same material. The first webbing 914 is not folded, while the second webbing 915 is folded at least once, such that the thickness of the second webbing 915 is greater than the thickness of the first webbing 914. Therefore, the hardness of the second webbing 915 is greater than that of the first webbing 914. Optionally, the first webbing 914 and the second webbing 915 may be made from the same webbing or may be made from two separate webbings sewn together. Similarly, the first webbing 914 and the second webbing 915 may pivot relative to each other at their connection point.

[0240] It should be noted that, regardless of the implementation method, the hardness of the positioning part 912 is greater than that of the main body part 911. This difference in hardness allows the positioning part 912 to effectively resist deformation when passing through the positioning hole 920, thereby ensuring that it passes through the positioning hole 920 stably and smoothly and abuts against the back surface 502 of the pad core 500.

[0241] like Figure 11B As shown, the positioning part 912 is provided with a connecting part C that connects to the second connecting end 9112 of the body part 911. The body part 911 and the positioning part 912 are movably connected at the connecting part C. When the positioning part 912 extends along the second axial direction, the connecting part C can be located on or away from the center line of the positioning part 912. That is, the connecting part C divides the positioning part 912 into a first positioning part 9121 and a second positioning part 9122 along the second axial direction. The lengths of the first positioning part 9121 and the second positioning part 9122 along the second axial direction can be the same or different. Preferably, the length of one of the first positioning part 9121 and the second positioning part 9122 is greater than the other. Specifically, the length L1 of the first positioning part 9121 is less than the length L2 of the second positioning part 9122, so that the positioning part 912 can pass through the positioning hole 920. The design of the first positioning part 9121 and the second positioning part 9122 having different lengths along the second axis facilitates the easy insertion or removal of the positioning part 912 into or out of the positioning hole 920.

[0242] When the main body 911 includes only the first belt 914 and the positioning part 912 includes the second belt 915 and the rigid plate 913, the part where the second belt 915 connects to the first belt 914 is the connecting part C of the positioning part 912. To ensure a more stable connection between the rigid plate 913 and the first belt 914, the connecting part C is provided with a stitch. The stitch passes through the rigid plate 913 from the outer surface of the second belt 915 to connect to the first belt 914. The stitch is located in the middle of the length extension direction of the positioning part 912 and is spaced apart from the center line of the length extension direction of the positioning part 912.

[0243] When the main body 911 includes only the first belt 914 and the positioning part 912 is only the rigid plate 913, the part where the rigid plate 913 connects to the first belt 914 is the connecting part C of the positioning part. In this case, the rigid plate 913 and the first belt 914 can be connected by a sewing thread. The sewing thread is set in the middle of the length extension direction of the positioning part 912 and is spaced apart from the center line of the length extension direction of the positioning part 912.

[0244] When the main body 911 includes only the first belt 914 and the positioning part 912 includes only the second belt 915, the connection point between the first belt 914 and the second belt 915 is the connecting part C of the positioning part. In this case, a sewing thread can also be provided at the connecting part C, and the sewing thread passes through the folded second belt 915 to connect to the first belt 914. The sewing thread is provided in the middle of the length extension direction of the positioning part 912 and is spaced apart from the center line of the length extension direction of the positioning part 912.

[0245] In this disclosure, the positioning structure 900 may include two positioning elements 910 and two positioning holes 920. The two positioning elements 910 are respectively connected to the first housing 830 and are spaced apart. The two positioning holes 920 respectively penetrate the front side 501 and back side 502 of the pad core 500 along a first axial direction and are spaced apart. In this embodiment, each positioning element 910 includes a body portion 911 and a positioning portion 912. The body portion 911 is accommodated in the positioning hole 920 and connected to the first housing 830. The positioning portion 912 is movably or detachably connected to the body portion 911 and protrudes from the back side 502 of the pad core 500. The two positioning portions 912 pass through the two positioning holes 920 one-to-one from the front side 501 of the pad core 500, protrude from the back side 502 of the pad core 500, and continue to extend relative to each other and connect to one another. The two positioning portions 912 can be connected to each other by Velcro, snap fasteners, straps, etc.

[0246] Figure 12 A perspective view of the outer cover 800 is schematically shown, in which a positioning hole 920 penetrates the cushion core 500. This positioning hole 920 can be configured as a through-hole extending along a first axial direction (front-to-back direction) through the front surface 501 and back surface 502 of the cushion core 500; this through-hole can be a through slot. In this embodiment, when the positioning part 912 passes through the positioning hole 920 and abuts against the back surface 502 of the cushion core 500, the length of the body part 911 (i.e., the distance between the first connecting end 9111 and the second connecting end 9112) is equal to the thickness of the cushion core 500, resulting in a tight abutment between the positioning part 912 and the positioning hole 920. Due to the tight abutment between the positioning part 912 and the positioning hole 920, the first body 830 of the outer cover 800 can fit more closely to the front surface 501 of the cushion core 500.

[0247] In this disclosure, the positioning hole 920 can be provided at the connection between the seat cushion 510 and the backrest cushion 520. In other embodiments, the positioning hole 920 can also be provided above the connection of the cushion core 500 and penetrate the cushion core 500 on a second axis (preferably vertical) intersecting the first axis. Furthermore, the positioning hole 920 can be provided at any position through the cushion core 500 as needed, as long as it can be connected to the corresponding positioning member 910.

[0248] Figures 13A-13BThe diagrams schematically show the state in which the positioning member 910 is passing through the positioning hole 920 and the state in which the positioning member 910 abuts against the back surface 502 of the pad core 500 after passing through the positioning hole 920.

[0249] The positioning unit 912 can be movably connected to the main body 911, such as... Figure 13A As shown, both the positioning part 912 and the body part 911 are configured to extend along the first axial direction toward the positioning hole 920. The second positioning part 9122 of the positioning part 912 passes through the positioning hole 920 first, and the first positioning part 9121 of the positioning part 912 and the body part 911 partially overlap. At this time, the positioning part 912 and the body part 911 are in a parallel state to each other; as shown Figure 13B As shown, after the second positioning part 9122 drives the first positioning part 9121 to pass through the positioning hole 920, the second positioning part 9122 extends upward relative to the positioning hole 920 in the second axis to abut against the back surface 502, and the first positioning part 9121 extends downward relative to the positioning hole 920 in the second axis to abut against the back surface 502, thereby making the positioning part 912 abut against the back surface 502 of the pad core 500. At this time, the positioning part 912 and the main body part 911 are in an intersecting state.

[0250] As described above, since the length of the main body 911 in the first axial direction is equal to or slightly less than the depth of the positioning hole 920 in the first axial direction, the positioning part 912 can fit tightly against the back surface 502 of the cushion core 500. Furthermore, in actual use, the weight of the infant sitting on the seat cushion 50 further enhances the stability of the contact, reducing the risk of the positioning part 912 accidentally detaching from the positioning hole 920, thereby achieving a tight fit between the first body 830 of the outer cover 800 and the front surface 501 of the cushion core 500.

[0251] When the outer cover 800 is to be removed from the pad core 500, firstly, the first positioning part 9121 of the positioning part 912 is pulled downward along the second axis and inserted into the positioning hole 920. Then, the first positioning part 9122 is pulled downward along the second axis and inserted into the positioning hole 920 until it is completely removed from the positioning hole 920, so that the positioning part 910 is disengaged from the positioning hole 920, thereby separating the outer cover 800 from the pad core 500 so that the outer cover 800 can be removed.

[0252] Although this disclosure is described herein by way of preferred embodiments, those skilled in the art will be able to make many possible modifications and alterations without departing from the scope of this disclosure.
