[0129] In order to make the objects, technical solutions and advantages of the present disclosure clearer, the present disclosure will be further described in detail below with reference to the drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present disclosure and do not limit the protection scope of the present disclosure.

[0130] It should be noted that when an element is referred to as being "fixed" to another element, it can be directly on the other element or there can be an intervening element. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or there can be an intervening element. The terms "vertical", "horizontal", "left", "right", and similar expressions used herein are for illustrative purposes only and are not intended to be limiting.

[0131] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used in the description herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0132] The present disclosure provides an infant carrier. As shown in FIGS. 1-3, the infant carrier comprises a waist belt 1, a shoulder belt 2, and a child support 3 connected to the waist belt 1 and the shoulder belt 2 respectively. The shoulder belt 2 is arranged along the longitudinal direction of the child support 3. One side of the child support 3 is connected to the waist belt 1, and the side of the child support 3 away from the waist belt 1 is detachably or non-detachably connected to the shoulder belt 2. That is, the upper side of the child support 3 is connected to the shoulder belt 2, and the lower side of the child support 3 is connected to the waist belt 1. In the present embodiment, the upper side of the child support 3 is detachably connected to the shoulder belt 2 by a connecting component (e.g. a buckle). In other embodiments, the child support 3 can be fixedly connected to the shoulder belt 2. The present disclosure does not limit the specific connection between the child support 3 and the shoulder belt 2. Referring to FIGS. 1-3, the child support 3 comprises a hip support 31 and a torso support 32 connected to each other. In the present embodiment, the child support 3 is integrally formed. The side of the hip support 31 away from the torso support 32 is connected to the waist belt 1, and the side of the torso support 32 away from the hip support 31 is connected to the shoulder belt 2.

[0133] It is worth noting that the longitudinal direction of the child support 3 described herein specifically refers to the direction from the side of the child support 3 connected to the waist belt 1 to the side of the child support 3 connected to the shoulder belt 2, i.e. the direction from the lower side to the upper side or the upper side to the lower side of the child support 3.

[0134] Further, as shown in FIGS. 1-3, the infant carrier further comprises a connecting piece 4 connected to the waist belt 1 and the shoulder belt 2. The connecting piece 4 and the child support 3 form a receiving space for accommodating an infant. The connecting piece 4 comprises a first connecting piece 41 and a second connecting piece 42. The first connecting piece 41 is a substantially rectangular piece of cloth. The number of first connecting pieces 41 is two, and the two first connecting pieces 41 are arranged in a spaced manner and connected to the corresponding shoulder belt 2. The two ends of the second connecting piece 42 are connected to the two first connecting pieces 41 respectively. In an embodiment, the connecting piece 4 can also be an integral piece of cloth, one side of the connecting piece 4 is connected to the waist belt 1, and the other side of the connecting piece 4 is connected to the shoulder belt 2. In yet another embodiment, the infant carrier can also not comprise the connecting piece 4, and the shoulder belt 2 directly extends to and is connected to the waist belt 1.

[0135] Referring to FIGS. 1-3, the side of the child support 3 away from the waistband 1 is detachably connected with the shoulder strap 2, so as to facilitate the baby to get in and out of the accommodation space. In use, the waistband 1 can be fixed to the waist of the caregiver, and the shoulder strap 2 is hung on the shoulders of the caregiver, at this time, the connecting piece 4 is attached to the torso of the caregiver, then the baby can be held and the side of the child support 3 away from the waistband 1 is connected with the shoulder strap 2, so that the baby is seated in the accommodation space. In the baby carrier of the embodiment, the accommodation space is formed by the connecting piece 4 and the child support 3, which has a good wrapping protection effect on the baby.

[0136] Further, as shown in FIGS. 3, 4, 6 and 7, the baby carrier further comprises leg supports 51. In the embodiment, there are two leg supports 51, which are respectively arranged on the two sides of the hip support portion 31 in the transverse direction, i.e. on the left and right sides of the hip support portion 31. The hip support portion 31 and the leg supports 51 form a seat area 101 for carrying the baby. One end of the leg support 51 is connected to the waistband 1 at one end of the hip support portion 31 and forms a first fixed end 511 of the leg support 51 and the hip support portion 31, and the other end of the leg support 51 is connected to the other end of the hip support portion 31 and forms a second fixed end 512 of the leg support 51 and the hip support portion 31. The natural longitudinal depth dimension L1 of the leg support 51 between the first fixed end 511 and the second fixed end 512 is smaller than the natural longitudinal depth dimension L2 of the hip support portion 31 between the first fixed end 511 and the second fixed end 512, so that the hip support portion 31 can be switched between the unfolded state and the folded state in the longitudinal depth direction of the child support 3. When the hip support portion 31 is in the unfolded state in the longitudinal depth direction, the size of the seat area 101 in the longitudinal depth direction is larger; when the hip support portion 31 is in the folded state in the longitudinal depth direction, the size of the seat area 101 in the longitudinal depth direction is smaller. In actual use, when the baby is seated in the seat area 101, the hip support portion 31 will be in the unfolded state due to the weight of the baby; when the baby is not seated in the seat area 101, the hip support portion 31 is in the natural folded state.

[0137] It is worth noting that the transverse direction of the child support 3 described herein specifically refers to the direction from the left side to the right side or from the right side to the left side of the child support 3, and the longitudinal direction of the child support 3 described herein specifically refers to the direction from the side of the child support 3 connected to the waist belt 1 to the side of the child support 3 connected to the shoulder belt 2, i.e. the direction from the lower side to the upper side or from the upper side to the lower side of the child support 3. The natural longitudinal dimension of the leg support 51 described herein between the first fixed end 511 and the second fixed end 512 refers to the actual length of the fabric forming the leg support 51 between the first fixed end 511 and the second fixed end 512 in the non-connected state. The natural longitudinal dimension of the hip support portion 31 described herein between the first fixed end 511 and the second fixed end 512 refers to the actual length of the fabric forming the hip support portion 31 between the first fixed end 511 and the second fixed end 512 in the non-connected state.

[0138] In the present embodiment, as shown in FIGS. 3-5, the hip support portion 31 is formed by a sheet of fabric. The hip support portion 31 is overall an axisymmetric figure, with the axis of symmetry being a longitudinal center line extending in the longitudinal direction of the child support 3. The hip support portion 31 has a first edge 311 on both sides in the transverse direction of the child support 3, i.e. both sides of the hip support portion 31 have a first edge 311. Taking one side of the first edge 311 as an example, the first edge 311 includes an arc-shaped segment 3111 and a recessed segment 3112 connected to each other. The arc-shaped segment 3111 extends gradually away from the longitudinal center line of the hip support portion 31 in the direction from the first fixed end 511 to the second fixed end 512. The recessed segment 3112 is connected to the arc-shaped segment 3111 and is recessed in the direction closer to the longitudinal center line of the hip support portion 31. In the manufacturing process, the hip support portion 31 can be first cut into the shape of the recessed segments 3112 on both sides from a substantially rectangular sheet of fabric, then folded into the shape of the arc-shaped segments 3111 on both sides, and finally stitched to form the shape of the first edge 311 described above. In the present embodiment, the arc-shaped segment 3111 extends outward, facilitating the formation of the widest support size away from the first fixed end 511, which benefits the baby to have the widest support area for the hips when riding, and at the same time, the arc-shaped segment 3111 forms the smallest support size close to the first fixed end 511, which facilitates the formation of the support and the fixed sewing connection with the waist belt 1 of the leg support 51. The recessed segment 3112 is close to the second fixed end 512. Due to the difference in longitudinal length between the leg support 51 and the hip support portion 31, by providing the recessed segment 3112, the leg support 51 is facilitated to be fixedly connected with the hip support portion 31 at the recessed segment 3112 through the second fixed end 512, and at the same time, it is also beneficial to provide the second opening 103 at the recessed segment 3112, which not only ensures the convenience of manufacturing, but also makes the whole body aesthetically pleasing.

[0139] Further, the hip support part 31 is provided with a first connecting part 312 at a position close to the first edge 311 on both sides of the child support 3 in the lateral direction.

[0140] In the embodiment, each of the leg support parts 51 is a substantially long strip-shaped fabric structure, and the shape and structure of each of the leg support parts 51 are substantially the same. Taking one of the leg support parts 51 as an example, as shown in FIGS. 3 and 4, the leg support part 51 has a first support part 513 and a second support part 514. The thickness of the first support part 513 is greater than the thickness of the second support part 514, and the thickness of the first support part 513 is greater than the thickness of the child support 3. In the embodiment, the thickness of the first support part 513 can be greater than the thickness of the second support part 514, and the thickness of the second support part 514 can be greater than the thickness of the child support 3. In this way, the thigh support part can provide stronger support for the thighs of the baby. In the embodiment, the first support part 513 can be a multi-layer structure, for example, a double-layer fabric filled with a hard filler such as paperboard or a flexible filler such as cotton, so that the first support part 513 has a greater thickness. As shown in FIG. 6, the second support part 514 covers the back of the hip support part 31 when the baby carrier is used to form a wing part for auxiliary support.

[0141] Specifically, as shown in FIG. 4 and FIG. 6, the leg support 51 comprises an outer edge 515 away from the hip support 31 and an inner edge 516 close to the hip support 31, and the outer edge 515 and the inner edge 516 are linear edges respectively. In this embodiment, since one end of the leg support 51 is connected to the waistband 1, the outer edge 515 of the leg support 51 can be designed as a linear edge, which is more aesthetic and convenient for processing. The leg support 51 also has a boundary edge 517 between the outer edge 515 and the inner edge 516. The part of the leg support 51 between the outer edge 515 and the boundary edge 517 forms a first support part 513, and the part of the leg support 51 between the inner edge 516 and the boundary edge 517 forms a second support part 514. In this embodiment, the leg support 51 is a long strip fabric structure sewn by double-layer cloth, and has an arc-shaped boundary edge 517 in the longitudinal direction of the child support 3. The boundary edge 517 can be a sewing line, thereby separating the leg support 51 into the first support part 513 and the second support part 514. The part close to the outer edge 515 is the first support part 513, which is filled with a hard filler or a soft filler as described above, and has a larger thickness, while the part close to the outer edge 515 is the second support part 514, which has no filler and is only a double-layer fabric structure, and thus has a smaller thickness. As shown in FIG. 3 and FIG. 4, due to the arc shape of the boundary edge 517, the first fixed end 511 is formed by one side of the first support part 513 and one side of the second support part 514, and the second fixed end 512 is formed by only one side of the second support part 514.

[0142] Further, as shown in FIG. 4 and FIG. 6, the leg support 51 is also provided with a second connecting part 518 connectable with the first connecting part 312. It can be understood that the second connecting part 518 is also a linear connecting part between the first fixed end 511 and the second fixed end 512. In this embodiment, the first connecting part 312 and the second connecting part 518 are sewn. Of course, in other embodiments, the first connecting part 312 and the second connecting part 518 can also be connected by bonding or the like. In this embodiment, the second connecting part 518 is located at the middle of the leg support 51 and is arranged along the boundary edge 517, i.e., the second connecting part 518 is arranged away from the outer edge 515 and also away from the inner edge 516.

[0143] Further, the first connecting part 312 and the second connecting part 518 can have various arrangement modes, so that the leg support 51 and the hip support 31 have different cooperation conditions.

[0144] For example, in the first embodiment, as shown in Figs. 6 to 8, the first connecting portion 312 and the second connecting portion 518 are both connected with the second fixed end 512 and are spaced apart from the first fixed end 511. The portion of the leg support 51 between the first fixed end 511 and the second connecting portion 518 forms the first opening 102 with the portion of the hip support 31 between the first fixed end 511 and the first connecting portion 312, i.e. the portion of the leg support 51 close to the waist belt 1 and the portion of the hip support 31 close to the waist belt 1 form the first opening 102.

[0145] In the second embodiment, as shown in Figs. 9 and 10, the first connecting portion 312 and the second connecting portion 518 are both located between the first fixed end 511 and the second fixed end 512 and are spaced apart from the first fixed end 511 and the second fixed end 512. The portion of the leg support 51 between the first fixed end 511 and the second connecting portion 518 forms the first opening 102 with the portion of the hip support 31 between the first fixed end 511 and the first connecting portion 312, and the portion of the leg support 51 between the second fixed end 512 and the second connecting portion 518 forms the second opening 103 with the portion of the hip support 31 between the second fixed end 512 and the first connecting portion 312, i.e. the portion of the leg support 51 close to the waist belt 1 and the portion of the hip support 31 close to the waist belt 1 form the first opening 102, and the portion of the leg support 51 away from the waist belt 1 and the corresponding portion of the hip support 31 away from the waist belt 1 form the second opening 103.

[0146] In the third embodiment, as shown in Fig. 11, the first connecting portion 312 and the second connecting portion 518 are both connected with the first fixed end 511 and are spaced apart from the second fixed end 512. The portion of the leg support 51 between the second fixed end 512 and the second connecting portion 518 forms the second opening 103 with the portion of the hip support 31 between the second fixed end 512 and the first connecting portion 312, i.e. the portion of the leg support 51 away from the waist belt 1 and the corresponding portion of the hip support 31 away from the waist belt 1 form the second opening 103.

[0147] In the fourth embodiment, as shown in Fig. 12, the first connecting portion 312 and the second connecting portion 518 continuously extend from the first fixed end 511 to the second fixed end 512, i.e. the leg support 51 and the hip support 31 are completely sewn together and no opening is formed between the leg support 51 and the hip support 31.

[0148] In the above embodiments, if the first opening 102 or the second opening 103 is formed between the leg support 51 and the hip support 31, it is beneficial for the flexible connection and adjustable movement between the leg support 51 and the first connecting portion 312.

[0149] Further, as shown in FIG. 5, the hip support portion 31 has two first edges 311 on both sides in the lateral direction. The distance W1 between the first fixed ends 511 of the two leg support members 51 located on both sides of the hip support portion 31 in the lateral direction is less than the maximum lateral width W2 between the two first edges 311 of the hip support portion 31. In this way, the infant can sit on the widest support area when riding, especially when the baby faces the user when riding, the baby's thighs can be supported on the narrower area close to the waistband, so that the thighs can form an ergonomic M-shaped leg.

[0150] It is worth noting that the maximum lateral width between the two first edges 311 of the hip support portion 31 described herein refers to the size of the fabric forming the hip support portion 31 in the connected state between the two first edges 311.

[0151] Further, as shown in FIG. 5, the hip support portion 31 has at least one linear fold 313 extending in the longitudinal direction of the child support member 3. Specifically, the linear fold 313 is formed by folding and sewing the hip support portion 31 in the lateral direction. In this embodiment, the hip support portion 31 has two spaced linear folds 313, and both linear folds 313 are located close to the waistband 1 of the hip support portion 31. The provision of the linear fold 313 also helps the hip support portion 31 to form a concave pocket-like structure in the middle.

[0152] Further, as shown in FIGS. 5 to 7, the lateral distance between the two second connecting portions 518 of the two leg support members 51 is less than the natural lateral width between the two first connecting portions 312 of the hip support portion 31 at least at one position. The natural lateral width between the two first connecting portions 312 of the hip support portion 31 described herein refers to the actual length of the fabric forming the hip support portion 31 in the unconnected state between the two first edges 311. In this way, in the lateral direction, the hip support portion 31 is in a crumpled state at least at one position. In this way, the hip support portion 31 can be switched between the folded state and the unfolded state in the lateral direction of the child support member 3.

[0153] Specifically, as shown in FIG. 6, when the baby carrier is in an unused state, the hip support part 31 is in a collapsed state in the lateral direction of the child support 3. As shown in FIG. 7, when the baby carrier is in a used state, i.e. a baby is seated in the baby carrier, the hip support part 31 is in an unfolded state in the lateral direction of the child support 3, and the degree of unfolding of the hip support part 31 can be self-adaptively adjusted according to the size of the baby. Specifically, when a baby with a larger size is seated in the baby carrier, the baby can press down the seat area 101 by its own larger weight, so that the hip support part 31 is pulled down and unfolded, the seat area 101 has a larger size in the longitudinal direction, and due to the tensile deformation of the hip support part 31, the force F exerted by the weight of the baby on the connection between the two sides of the hip support part 31 and the corresponding two leg support parts 51 is larger, so that the hip support part 31 is stretched to a larger extent in the lateral direction of the child support 3, the two leg support parts 51 expand away from each other, and the seat area 101 is enlarged to support the baby with a larger size, so that the baby's legs form an ergonomic M-shaped leg. When a baby with a smaller size is seated in the baby carrier, the baby's weight is smaller and the hip size is smaller, so the hip support part 31 is not pulled down too much, the hip support part 31 is stretched to a smaller extent in the lateral direction of the child support 3, the seat area 101 has a smaller size in the longitudinal direction, and the force F exerted by the baby's weight on the connection between the two sides of the hip support part 31 and the corresponding two leg support parts 51 is smaller, so that the hip support part 31 is unfolded to a smaller extent in the lateral direction of the child support 3, the two leg support parts 51 are relatively close to each other, and the seat area 101 is reduced to accommodate a baby with a smaller size, so that the baby's legs form an ergonomic M-shaped leg.

[0154] Of course, in other embodiments, the first connection part 312 and the second connection part 518 can also not be directly connected. As shown in FIG. 14, the hip support part 31 and the leg support part 51 are elastically connected. Specifically, an elastic member 52 can be connected between the hip support part 31 and the leg support part 51, and the elastic member 52 can be switched between an extended state and a non-extended state. In this embodiment, the elastic member 52 is an integral elastic part. In other embodiments, the elastic member 52 can also be at least one elastic band. The two sides or two ends of the elastic member 52 in the lateral direction of the child support 3 are connected to the first connection part 312 and the second connection part 518, respectively, to provide sufficient elastic support to the seat area 101.

[0155] When the baby carrier is in the non-use state, the elastic member 52 is in the non-extended state. When the baby carrier is in the use state, i.e. the baby is seated in the baby carrier, the elastic member 52 is in the extended state, and the degree of extension of the elastic member 52 can be self-adaptively adjusted according to the body size of the baby. When the baby carrier carries a baby with a larger body size, the elastic member 52 will be in a larger degree of extension under the action of the larger gravity and larger hip size of the baby, so that the size of the seat region 101 in the transverse direction is increased, thereby being suitable for the baby with a larger body size to be seated, and the legs of the baby can form the ergonomic "M" type legs. When the baby carrier carries a baby with a smaller body size, the elastic member 52 will be in a smaller degree of extension under the action of the smaller gravity and smaller hip size of the baby, so that the baby with a smaller body size can be seated, and the legs of the baby can form the ergonomic "M" type legs.

[0156] In another aspect, the present disclosure also provides a baby carrier. The baby carrier has a leg support 51, a waist belt 1, a shoulder belt 2, and a child support 3 connected to the waist belt 1 and the shoulder belt 2, respectively. A portion of the child support 3 close to the waist belt 1 forms a hip support 31. Two leg supports 51 are arranged on both sides of the hip support 31 in the transverse direction. One end of the leg support 51 and one end of the hip support 31 are connected to the waist belt 1 and form a first fixed end 511 of the leg support 51 and the hip support 31. The other end of the leg support 51 and the other end of the hip support 31 are connected and form a second fixed end 512 of the leg support 51 and the hip support 31. Both sides of the hip support 31 in the transverse direction have a first edge 311. The distance W1 between the first fixed ends 511 of the two leg supports 51 on both sides of the hip support 31 in the transverse direction is less than the maximum transverse dimension W2 between the two first edges 311. In this way, it can be ensured that the hip support 31 can form a concave pocket when the baby is seated. Specifically, when the baby is seated in the baby carrier, the seat region 101 is pressed downward by the gravity of the baby, so that the two leg supports 51 on both sides of the hip support 31 move away from each other. At the same time, the hip support 31 is pressed to form a support, and the seat region 101 is increased, so that the seated baby can form the ergonomic "M" type legs.

[0157] In another aspect, the present disclosure provides a baby carrier. The baby carrier has a leg support 51, a waist belt 1, a shoulder strap 2, and a child support 3 connected to the waist belt 1 and the shoulder strap 2, respectively. One end of the leg support 51 and one end of a hip support 31 are connected to the waist belt 1 and form a first fixed end 511 of the leg support 51 and the hip support 31. Another end of the leg support 51 and another end of the hip support 31 are connected and form a second fixed end 512 of the leg support 51 and the hip support 31. In at least one position, a transverse width distance between two second connecting portions 518 of the two leg supports 51 is less than a natural transverse width dimension between two first connecting portions 312 of the hip support 31. In this way, the hip support 31 is switchable between a folded state and an unfolded state in a transverse width direction of the child support 3.

[0158] In particular, when the baby carrier is in an unused state, the hip support 31 is in the folded state in the transverse width direction of the child support 3. When the baby carrier is in a used state, i.e., a baby is seated in the baby carrier, the hip support 31 is in the unfolded state in the transverse width direction of the child support 3, and the degree of unfolding of the hip support 31 can be adaptively adjusted according to the size of the baby. In particular, when a larger baby is seated in the baby carrier, the baby can press down the seat area 101 by its own larger weight, so that the hip support 31 is stretched downward to be in the unfolded state. The seat area 101 has a larger dimension in the longitudinal direction, and due to the stretching deformation of the hip support 31, a larger force F generated by the gravity of the baby on the connecting portions between the two sides of the hip support 31 and the corresponding two leg supports 51 causes the hip support 31 to be stretched to a larger degree in the transverse width direction of the child support 3, and the two leg supports 51 expand in the direction away from each other, and in combination with the hip support 31 being pressed to be concave, the seat area 101 is enlarged, so as to be suitable for a larger baby to be seated, and the legs of the baby can form an ergonomic M-shaped leg. When a smaller baby is seated in the baby carrier, since the gravity of the baby is smaller and the hip size is smaller, the hip support 31 will not be stretched downward too much, so that the hip support 31 is stretched to a smaller degree in the transverse width direction of the child support 3, and the seat area 101 has a smaller dimension in the longitudinal direction, and the force F generated by the gravity of the baby on the connecting portions between the two sides of the hip support 31 and the corresponding two leg supports 51 is smaller, so that the degree of unfolding of the hip support 31 in the transverse width direction of the child support 3 is smaller, and the two leg supports 51 are relatively close, so that the seat area 101 is reduced, so as to be suitable for a smaller baby to be seated, and the legs of the baby can form an ergonomic M-shaped leg.

[0159] The baby carrier has at least the following technical effects:

[0160] In the baby carrier, the waistband 1 and the shoulder band 2 are respectively connected to the two sides of the longitudinal direction of the child support 3, and the part of the child support 3 close to the waistband 1 forms the hip support part 31. The leg support 51 is arranged on one side of the transverse direction of the hip support part 31, and the two ends of the leg support 51 are respectively connected to one end of the hip support part 31 as the first fixed end 511 and the second fixed end 512. The natural longitudinal dimension of the leg support 51 between the first fixed end 511 and the second fixed end 512 is smaller than the natural longitudinal dimension of the hip support part 31 between the first fixed end 511 and the second fixed end 512, so that the hip support part 31 can be switched between the expanded state and the contracted state in the longitudinal direction of the child support 3. In this way, when the baby carrier carries a baby with a larger body type, the hip support part 31 will be elongated downward under the gravity of the baby and be in the expanded state, so that the size of the seat area 101 in the longitudinal direction is larger to adapt to the larger body type of the baby. When the baby carrier carries a baby with a smaller body type, the hip support part 31 will be in the contracted state due to the smaller gravity of the baby, so that the size of the seat area 101 in the longitudinal direction is smaller to adapt to the smaller body type of the baby. In this way, the baby carrier can adaptively adjust the size of the seat area 101 according to the body type of the baby, and has a simple structure and is convenient to use.

[0161] In addition to the above embodiments, the present application also provides another baby carrier. Referring to FIG. 15 and FIG. 16, the baby carrier has leg supports 51, a waist belt 1, shoulder belts 2, and child supports 3 connected to the waist belt 1 and the shoulder belts 2, respectively. The part of the child supports 3 close to the waist belt 1 also forms a hip support 31. Two leg supports 51 are arranged on both sides of the hip support 31 in the transverse direction. The leg supports 51 include first connecting ends 510 and second connecting ends 519 arranged in the longitudinal direction, and the leg supports 51 are connected to the hip support 31 through the first connecting ends 510 and pivotally connected to the child supports 3 through the second connecting ends 519. In this embodiment, specifically, the leg supports 51 are fixedly connected to the hip support 31 through the first connecting ends 510, so the first connecting ends 510 are also called fixed ends 510, and the second connecting ends 519 are also called pivotally connected ends 519. Of course, in other embodiments, the leg supports 51 can also be non-fixedly connected to the hip support 31 through the first connecting ends 510. In this way, when the baby is not seated on the baby carrier, the leg supports 51 of the baby carrier are initially in a folded state; when the baby is seated on the baby carrier, the baby's body weight presses the hip support and the leg supports, and thanks to the fact that one end of the leg supports 51 can pivot relative to the hip support 31, the two leg supports 51 can self-adaptively expand in directions away from each other, so that the leg supports are in an unfolded state, thereby achieving good support for the baby's thighs and achieving an M-shaped leg favorable seating posture. In addition, since babies of different ages have different body weights, the degree of their pressing on the hip support and the leg supports is different, so when babies of different ages are seated on the baby carrier, the effective seat width of the baby carrier is different. Of course, the user of the baby carrier can also manually adjust the degree of expansion of the two leg supports 51 in directions away from each other to adapt to other possible use scenarios.

[0162] Preferably, two leg supports 51 are arranged on both sides of the child supports 3 in the transverse direction, and the expansion directions of the two leg supports 51 relative to the child supports 3 are opposite. Specifically, when the baby is placed on the baby carrier for seating, the two leg supports 51 expand in opposite directions relative to the child supports 3. Each leg support 51 is respectively provided with a fixed end 510 and a pivotally connected end 519. The two connection points of the child supports 3 with the fixed ends 510 are respectively located on both sides of the child supports 3 in the transverse direction, and the two support points of the child supports 3 with the pivotally connected ends 519 are also respectively located on both sides of the child supports 3 in the transverse direction.

[0163] In some embodiments, referring to FIG. 18A, in a state where the pivot end 519 of the leg support 51 is not connected to the child support 3, the distance between the fixed end 510 and the pivot end 519 of the leg support 51 in the longitudinal direction is less than the distance between the connection of the fixed end 510 and the connection of the pivot end 519 on the child support 3. In this way, in the initial state of the baby carrier, i.e., when the baby carrier is not worn, the hip support 31 is more prone to be in a crumpled state in the longitudinal direction, and thus a pouch-like structure can be easily formed, thereby improving the wrapping and supporting performance on the hips of the baby.

[0164] In some embodiments, referring to FIGS. 15, 18A and 18C, in the lateral direction, both sides of the child support 3 form a concave position 310, and the connection point of the child support 3 and the pivot end 519 of the leg support 51 is slightly higher than the position with the maximum concave degree of the concave position 310. In this way, in the longitudinal direction, the position near the middle of the hip support 31 has an inward converging structure, which also helps to form a pouch-like structure when the baby is seated, thereby further improving the wrapping and supporting performance on the hips of the baby.

[0165] In some embodiments, the leg support 51 has a connection section 53 and a support section 54, and the support section 54 is located laterally outside the connection section 53. Taking one of the leg supports 51 as an example, referring to FIGS. 18A and 18C, similar to the previous embodiments, the leg support 51 includes an outer edge 515 away from the hip support 31 and an inner edge 516 close to the hip support 31, and the leg support 51 also has a boundary edge 517 between the outer edge 515 and the inner edge 516, which can be a sewing line, thereby separating the connection section 53 and the support section 54. In this embodiment, the leg support 51 has an arc-shaped boundary edge 517 approximately in the longitudinal direction of the child support 3 approximately in the middle. Among them, the part close to the outer edge 515 is the support section 54, which is filled with hard or soft filler, and the part close to the inner edge 516 is the connection section 53, which is not filled with filler. For example, the connection section 53 is a soft fabric, and thus the connection section 53 can be crumpled to form a wrinkle, thereby changing its effective size in the lateral direction, i.e., the lateral size. It can be understood that, on the one hand, in the initial state of the baby carrier, the connection section 53 is in a crumpled state, so that the effective lateral size of the leg support is smaller, and thus the baby carrier has better aesthetics; on the other hand, when the baby is seated in the baby carrier, since the connection section 53 can be unfolded in the lateral direction, the support section has a certain degree of pivoting freedom, and under the cooperation of the pivot end 519, the self-adaptive degree of the two leg supports 51 expanding in the direction away from each other is further improved, and thus the M-shaped leg of the baby carrier can be realized for babies of different ages (weights).

[0166] Referring to FIGS. 17A and 17B. FIG. 17A is a schematic view of the leg support 51 in a collapsed state, in which the leg support 51 is less expanded, and only the first support section 541 and part of the second support section 542 extend in the transverse direction to the extent that they are not blocked by the hip support 31. FIG. 17B is a schematic view of the leg support 51 in an expanded state, in which the leg support 51 is more expanded, and the first support section 541, the second support section 542, and part of the connecting section 53 all extend in the transverse direction to the extent that they are not blocked by the hip support 31.

[0167] Preferably, in some embodiments, the thickness of the support section 54 is greater than the thickness of the connecting section 53. The greater thickness of the support section 54 is conducive to achieving a favorable support on the thighs of the infant, thereby achieving a favorable sitting posture of the M-shaped legs. The smaller thickness of the connecting section 53 is conducive to the expansion and contraction of the connecting section 53, thereby achieving the conversion of the leg support 51 between the expanded state and the collapsed state.

[0168] Preferably, in some embodiments, the support section 54 of the leg support 51 includes a first support section 541 and a second support section 542. Referring to FIGS. 18A, 18C, and 18D, the leg support 51 is provided with a third connecting portion 5422 and a fourth connecting portion 5423, both of which are linear connecting portions between the pivot end 519 and the fixed end 510, and the third connecting portion 5422 and the fourth connecting portion 5423 are oppositely arranged. The second support section 542 is connected to the connecting section 53 through the third connecting portion 5422, and the first support section 541 is connected to the second support section 542 through the fourth connecting portion 5423, so that the first support section 541, the second support section 542, and the connecting section 53 are sequentially connected in the transverse direction of the hip support 31. Specifically, for the leg support 51, the first support section 541 is located at the outermost side in the transverse direction, the connecting section 53 is located at the innermost side in the transverse direction, and the second support section 542 is located between the two.

[0169] Further, referring to FIG. 18A, the natural size of the connecting section 53 in the transverse direction will be greater than the distance between the inner edge 516 and the third connecting portion 5422, where the natural size refers to the size of the connecting section 53 in the naturally expanded state without being connected to the child support 3 and the leg support 51. Therefore, in the initial state of the baby carrier, as shown in FIGS. 18A and 18D, the connecting section 53 will be wrinkled in the transverse direction so as to be stretched to form a pocket-shaped structure when the infant is seated.

[0170] Referring to FIG. 18D, in the present embodiment, the thickness of the first support section 541 is set to be greater than the thickness of the second support section 542. Specifically, the thickness of the first support section 541 is set to be greater than the thickness of the second support section 542, which can be achieved by setting the filling amount of the soft filler in the first support section 541 to be greater than the filling amount of the soft filler in the second support section 542, or by setting the thickness of the hard filler in the first support section 541 to be greater than the thickness of the hard filler in the second support section 542, or by other means, which are not limited in the present application. It can be understood that when the infant is seated in the infant carrier of the present embodiment, the first support section 541 is less likely to be folded due to its greater thickness than the second support section 542, and the first support section 541 can provide more obvious support to the second support section 542, and the overall structure of the leg support 51 is more reasonable, and the M-shaped leg sitting posture is more easily formed.

[0171] In some embodiments, the thickness of the second support section 542 is greater than the thickness of the connecting section 53. In this arrangement, the thickness of the first support section 541 is greater than the thickness of the second support section 542, and the thickness of the second support section 542 is greater than the thickness of the connecting section 53. It can be understood that in the direction towards the outside of the lateral width of the infant carrier, the thickness of the leg support 51 gradually increases, which is particularly advantageous for forming the M-shaped leg sitting posture. At the same time, the connecting section 53 is more easily expanded and shrunk in the lateral width direction due to its thinnest thickness. Preferably, the leg support 51 is provided with a first pivot hole 551, which can be used to rivet a rivet or other pivot member to pivot the leg support 51 with the child support 3. In the present embodiment, the first pivot hole 551 is provided on the support section 54 of the leg support 51 rather than the connecting section 53, because the thickness of the support section 54 is thicker than the connecting section 53, thereby providing the necessary rigidity for the connection and pivoting of the pivot end 519. Preferably, the first pivot hole 551 is provided on the second support section 55, which has a moderate thickness compared to the first support section 54 and the connecting section 53, and can provide the necessary rigidity for the connection and pivoting of the pivot end 519, while avoiding the difficulty of rotating the pivot end 519.

[0172] Optionally, referring to FIG. 18A and FIG. 18B, in some embodiments, the child support 3 comprises a body layer 33 as a body part. On the inner side of the baby carrier, i.e. the side of the baby carrier that contacts the baby when the baby is seated on the baby carrier, a reinforcing layer 34 is attached to the body layer 33, covering part of the area of the body layer 33. In this embodiment, the reinforcing layer 34 is attached to the body layer 33 by stitching, but the application does not limit the form of attachment of the reinforcing layer 34 to the body layer 33 in other embodiments. On the inner side of the baby carrier, the area of the body layer 33 not covered by the reinforcing layer 34 forms a thinned area 35. The thinned area 35 is located in the middle area in the transverse direction of the child support 3, and extends in the longitudinal direction of the child support 3, so that the thinned area 35 covers most of the area of the torso and hips of the baby seated on the baby carrier, thereby providing better heat dissipation and air permeability. Preferably, the body layer 33 is formed of air-permeable fabric, thereby optimizing the heat dissipation and air permeability of the thinned area 35. Preferably, the reinforcing layer 34 covers at least the shoulder strap area of the child support 3 and the area on both sides of the hip support 31, thereby providing the necessary strength for the actual use of the baby carrier. In some embodiments, the inner edge 516 of the leg support 51 extends parallel to the adjacent edge of the thinned area 35. Optionally, the connection points of the child support 3 to the pivot ends of the two leg supports 51 are located in the area of the reinforcing layer 34 and on both sides of the thinned area 35.

[0173] In some embodiments, the child support 3 and the leg supports 51 are detachably connected to the waist belt 1. Referring to FIG. 16, specifically, the child support 3 is provided with a waist belt connection side 36 in the longitudinal direction, and the waist belt connection side 36 and the waist belt 1 are provided with corresponding connectors (not shown in the figure), and the child support 3 and the leg supports 51 are detachably connected to the waist belt 1 at the waist belt connection side 36. Of course, the child support 3 and the leg supports 51 can also be fixedly connected to the waist belt 1.

[0174] As shown in FIG. 15 and FIG. 18A, the leg support 51 is connected to the inner face of the child support 3. Specifically, the connecting section 53 of the leg support 51 is connected to the vicinity of the lateral width edge of the hip support portion 31 on the inner face of the child support 3, the fixed end 510 of the leg support 51 is connected to the waistband connecting side 36 on the inner face of the child support 3, and the pivoting end 519 of the leg support 51 is also connected to the inner face of the child support 3. Preferably, at the fixed end 510 of the leg support 51, or in other words, at the waistband connecting side 36 of the child support 3, the outer edge 515 of the leg support 51 is offset from the outer edge of the corresponding hip support portion 31 in the lateral width direction. Specifically, in the lateral width direction, the outer edge 515 of the leg support 51 is located outward of the outer edge 315 of the corresponding hip support portion. That is, as shown in FIG. 18C, viewed from the outer face of the child support 3, in the lateral width direction, the fixed end 510 of the leg support 51 is partially exposed outward of the hip support portion 31. Preferably, at the fixed end 510 of the leg support 51, in the lateral width direction, the outer edge 315 of the hip support portion is located between the outer edge 515 of the leg support 51 and the third connecting portion 5422. In this way, in the initial state (i.e. the non-use state) of the baby carrier, a large portion of the leg support 51 can be shielded within the child support 31, improving the overall aesthetics of the baby carrier, while not affecting the unfolding and folding functions of the leg support 51.

[0175] In some embodiments, the first support section 541 is formed with an outward protrusion 5150. Referring to FIG. 18A and FIG. 18C, the outward protrusion 5150 protrudes away from the second support section 542. Understandably, when the pivoting end 519 of the leg support 51 and the hip support portion 31 are in the pivoted state, the outward protrusion 5150 is substantially aligned with the inward recess 310 of the hip support portion 31 in the lateral width direction. In this way, the support strength of the child support 3 on the baby in the corresponding lateral width direction at the inward recess 310 can be reinforced.

[0176] In some embodiments, the first end of the connecting segment 53 and the support segment 54 and the child support 3 enclose a first opening 55 in the longitudinal direction, and the second end of the connecting segment 53 and the support segment 54 and the child support 3 also enclose a second opening 56 in the longitudinal direction. Referring to FIG. 20, in the present embodiment, the first end is the lower end of the connecting segment 53 in the longitudinal direction, and the second end is the upper end of the connecting segment 53 in the longitudinal direction. Referring to FIG. 18A, the first opening 55 is enclosed by the lower end of the connecting segment 53, the support segment 54 and the child support 3, but at this time, since the pivot end 519 is not connected with the child support 3, the second opening 56 has not yet been formed. Referring to FIG. 20, when the pivot end 519 is connected with the child support 3, the second opening 56 is enclosed by the upper end of the connecting segment 53, the support segment 54 and the child support 3. Since the second opening 56 is covered by the cover 7, the second opening 56 is shown by a dashed line in FIG. 20, which only shows the approximate position of the second opening 56 and does not limit the specific position and shape of the second opening 56. By forming the first opening 55 and the second opening 56, the connecting segment 53 is easier to unfold or shrink, and the use experience can be improved.

[0177] In some embodiments, the baby carrier further comprises a pivot assembly 6. Referring to FIG. 19A, in one implementation of the baby carrier in the present embodiment, the pivot assembly 6 comprises a first pivot piece 61 and a second pivot piece 62, wherein the first pivot piece 61 is similar to a rivet and comprises a pivot shaft 611 and a first stopper 612 fixedly connected to one end of the pivot shaft 611, and the first stopper 612 is approximately disc-shaped. The second pivot piece 62 comprises a second stopper 621 which is approximately disc-shaped and a fastening portion 622 protruding from the circular outer surface of the second stopper 621. The pivot shaft 611 is provided with a fastening groove (not labeled in the figure), and the fastening portion 622 is inserted into the fastening groove. Preferably, the fastening portion 622 produces friction with the groove wall of the fastening groove without relative sliding, so that the first pivot piece 61 and the second pivot piece 62 are fixedly connected. In the present embodiment, the second support segment 55 is provided with a first pivot hole 551, and the hip support portion 31 is provided with a second pivot hole 314, and the pivot shaft 611 is simultaneously inserted into the first pivot hole 551 and the second pivot hole 314 and is in clearance fit with the first pivot hole 551 and the second pivot hole 314, so that the second support segment 55 and the hip support portion 31 can relatively rotate about the pivot shaft 611, that is, the leg support 51 is pivotally connected with the hip support portion 31. Understandably, the first stopper 612 and the second stopper 621 can prevent the second support segment 55 and the hip support portion from being separated from each other, and can effectively maintain the articulated state of the second support segment 55 and the hip support portion.

[0178] In another implementation of the baby carrier, the fastening portion 622 is not integrally formed with the second stopper 621. As shown in FIG. 19B, the second stopper 621 is provided with a counterbore, the fastening portion 622 is provided with external threads, and the fastening portion 622 can be screwed through the counterbore and threadedly engaged with the inner wall of the fastening groove. Understandably, by tightening the fastening portion 622, the second stopper 621 can be stopped against the pivot shaft 611, and the same effect of fixedly connecting the first pivot member 61 and the second pivot member 62 can also be achieved.

[0179] In some embodiments, the baby carrier is further provided with a cover portion 7 located on the side surface of the leg support 51 on which the baby is seated, i.e., the inner surface of the child support 3. Referring to FIGS. 15 and 20, the cover portion 7 is connected to the area of the pivot end 519 of the leg support 51, and the cover portion 7 is also formed of fabric. Specifically, the cover portion 7 covers the connecting segment 53, the second support segment 542, and part of the top end of the support segment 54. Understandably, the pivot assembly 6 and the first pivot hole 551 are also covered by the cover portion 7. Therefore, when the baby is seated on the baby carrier, the baby's skin is protected by the cover portion 7 and is not directly in contact with the pivot assembly 6, preventing the baby seated on the baby carrier from feeling uncomfortable or even skin abrasion caused by the pivot assembly 6.

[0180] Optionally, the cover portion 7 is not completely connected to the leg support 51. The cover portion 7 is sewn to the first support segment 54 and the connecting segment 53, but the cover portion 7 is not sewn to the second support segment 55. Since the cover portion 7 and the second support segment 55 are both formed of fabric and are plastic, the cover portion 7 and the second support segment 55 can be spread apart from each other to form a pocket-like structure between the cover portion 7 and the leg support 51. In this way, when the pivot assembly 6 is installed, the first pivot member 61 can be placed in the pocket-like structure, and then the first pivot member 61 and the second pivot member 62 can be connected. Therefore, the pocket-like structure formed by the cover portion 7 and the leg support 51 not only facilitates the installation of the pivot assembly 6, but also facilitates sewing, reducing the operation difficulty. Of course, the pivot assembly 6 can also be installed first, and then the cover portion 7 can be sewn to the pivot end of the leg support. The cover portion 7 can also be completely sewn to the leg support without forming a pocket-like structure.

[0181] In the exemplary embodiment, referring to FIGS. 18A and 18C, the pivot end 519 is connected to a specific connection point of the child support 3, i.e., the position of the second pivot hole 314 in the embodiment. Compared with the connection point of the pivot end 519 and the child support 3, the connection between the fixed end 510 and the waistband connection side 36 is located on the outer side in the transverse direction. In other words, compared with the connection between the fixed end 510 and the waistband connection side 36, the connection point of the pivot end 519 and the child support 3 is closer to the middle of the child support 3 in the transverse direction. Thus, when the infant is seated on the infant carrier, it helps the infant's legs to assume an M-shaped posture, improving the stability during seating. The pivotable range of the position of the leg support 51 near the pivot end 519 is greater than the pivotable range of the position of the leg support 51 near the fixed end 510.

[0182] In some embodiments, as shown in FIGS. 21 and 22, the infant carrier further comprises a height adjustment member 40, which is a fabric connected to the front side of the shoulder strap 2 in the transverse direction, and the waistband connection side 36 of the child support 3 can be detachably connected to the waistband 1 or the height adjustment member 40 so that the hip support portion 31 of the child support 3 is at different heights, thereby adjusting the different seating heights of the infant to accommodate infants of different sizes. The position of the waistband connection side 36 is shown in FIGS. 18A and 18C.

[0183] Referring to FIGS. 15 and 16, the connection relationship of the shoulder strap 2 is described by taking one of the shoulder straps 2 as an example. The bottom end of the shoulder strap 2 in the longitudinal direction is a first end, which is fixedly connected to the waistband 1. Referring to FIGS. 21 and 22, when the infant carrier is used, as shown in FIG. 22, the shoulder strap 2 is wrapped around the back of the user after passing through the user's shoulder. The shoulder strap 2 also has a second end, which has a bifurcated structure forming a first connection strap 21 and a second connection strap 22. The first connection strap 21 is fixedly connected to the front of the shoulder strap 2. The second connection strap 22 is detachably connected to the child support 3. In the embodiment, the second connection strap 22 is provided with a first connection structure 221, and the torso support portion 32 is provided with a second connection structure 321. The second connection structure 321 cooperates with the first connection structure 221, so that the second connection strap 22 can be detachably connected to the child support 3. In some embodiments, the first connection structure 221 and the second connection structure 321 are male and female buckles of a magnetic buckle. Of course, the first connection structure 221 and the second connection structure 321 can also be other forms of connection structures.

[0184] In some embodiments, the infant carrier is further provided with a leg opening limiting assembly 8. The leg opening limiting assembly 8 comprises a first fixing part 81 arranged on the first connecting belt 21 and a second fixing part 82 arranged on the second connecting belt 22. As shown in FIG. 22, when the first fixing part 81 and the second fixing part 82 are not in a connecting relationship, the leg supporting part 51 and the opening formed by the torso supporting part 32 and the body of the user are relatively large in the transverse direction. As shown in FIG. 21, when the first fixing part 81 and the second fixing part 82 are in a connecting relationship, the distance between the front part of the shoulder belt 2 and the child supporting part 3 can be shortened, thereby reducing the opening formed by the leg supporting part 51, the torso supporting part 32 and the body of the user, and improving the wrapping and supporting performance of the infant's legs.

[0185] In the present embodiment, the first fixing part 81 is a button and the second fixing part 82 is a buttonhole. In other embodiments, the first fixing part 81 and the second fixing part 82 can also be other forms of connecting members, which are not limited in the present application.

[0186] In particular, other embodiments of the present application also provide another infant carrier, which is different from the above-mentioned infant carrier in that the leg supporting part 51 of the infant carrier is respectively provided with a first connecting end and a second connecting end in the longitudinal direction, and the leg supporting part 51 is pivotally connected to the hip supporting part 31 through the first connecting end and pivotally connected to the child supporting part 3 through the second connecting end. In this way, when the infant is seated on the infant carrier, the two leg supporting parts 51 can also adaptively expand in the direction away from each other, and the degree of adaptive expansion is higher, so that the leg supporting part is in an unfolded state, thereby achieving good support for the thighs of the infant and achieving the advantageous riding posture of M-shaped legs. The other structures and features of the present embodiment are the same as those of the foregoing embodiments.

[0187] Referring to Figs. 23-28, other embodiments of the present application also provide yet another baby carrier which also includes two leg supports 51 disposed on the two outer sides of the hip support portion 31 along the lateral width direction. As shown in Figs. 27 and 28, each of the leg supports 51 includes a first connecting end 510 and a second connecting end 519 disposed along the longitudinal depth direction, which are both pivotally connected with the child support 3. Thus, when the baby is not seated in the baby carrier, referring to Fig. 27, the leg supports 51 of the baby carrier are initially in the collapsed state; when the baby is seated in the baby carrier, referring to Fig. 28, due to the compression of the hip support portion 31 and the leg supports 51 by the body weight of the baby, since the first connecting end 510 and the second connecting end 519 of the leg supports 51 can both pivot relative to the hip support portion 31, the two leg supports 51 can be self-adaptively unfolded away from each other along the lateral width direction, and the degree of self-adaptive unfolding is higher, so that the leg supports 51 are in the unfolded state, forming a cradle-shaped seat portion region, thereby achieving good support for the thighs of the baby and achieving the advantageous seating posture of M-shaped legs.

[0188] The first connecting end 510 and the second connecting end 519 of the leg support 51 can be pivotally connected with the child support 3 in various ways. For example, referring to Fig. 26, the first connecting end 510 and the second connecting end 519 can be pivotally connected with the child support 3 by means of the pivot structures 51A, 51B. The pivot structures 51A, 51B can adopt the aforementioned pivot assembly 6, or other structures, as long as they can pivotally connect the first connecting end 510 and the second connecting end 519 with the child support 3. The pivot structures 51A, 51B can include two upper pivot structures 51A away from the waistband connecting side 36 along the longitudinal depth direction and two lower pivot structures 51B close to the waistband connecting side 36 along the longitudinal depth direction. The upper pivot structures 51A are used to pivotally connect the second connecting end 519 with the child support 3. The lower pivot structures 51B are used to pivotally connect the first connecting end 510 with the child support 3.

[0189] Referring to Fig. 25, in order to enable the hip support portion 31 of the child support 3 to be at different heights, so as to adapt to babies of different sizes by adjusting the different seating heights of the baby, the baby carrier can also include the height adjustment member 40 as described above, which is connected to the front of the shoulder strap 2 and above the waistband 1. The waistband connecting side 36 (see Fig. 26) of the child support 3 is detachably connected to the waistband 1 or the height adjustment member 40 so that the hip support portion 31 of the child support 3 is at different heights.

[0190] The waistband connecting side 36 of the child support 3 can be detachably connected to the waistband 1 or the height adjustment member 40. For example, referring to FIG. 26, the waistband connecting side 36 is provided with a first engaging member 36Z. Correspondingly, referring to FIG. 25, the waistband 1 is provided with a third engaging member 1Z which is detachably connected to the first engaging member 36Z, and the third engaging member 1Z is in the first height position PI. The height adjustment member 40 is provided with a second engaging member 40Z which is also detachably connected to the first engaging member 36Z, and the second engaging member 40Z is in the second height position P2 which is above the first height position PI. When the first engaging member 36Z of the waistband connecting side 36 is connected to the third engaging member 1Z of the waistband 1, the hip support portion 31 of the child support 3 is in a lower position, as shown in FIG. 23, to accommodate a larger infant. When the first engaging member 36Z of the waistband connecting side 36 is connected to the second engaging member 40Z of the height adjustment member 40, the hip support portion 31 of the child support 3 is in a higher position, as shown in FIG. 24, to accommodate a smaller infant.

[0191] To facilitate the detachable connection of the waistband connecting side 36 of the child support 3 to the waistband 1 or the height adjustment member 40, referring to FIGS. 25 and 26, the length A1 of the third engaging member 1Z of the waistband 1 in the transverse direction, the length A2 of the second engaging member 40Z of the height adjustment member 40 in the transverse direction, and the length B1 of the first engaging member 36Z of the child support 3 in the transverse direction are equal. In this embodiment, the first, second and third engaging members 36Z, 40Z and 1Z are zippers, but in other embodiments, they can be other suitable engaging members, such as Velcro, etc.

[0192] In addition, referring to FIG. 26, the distance B2 between the two lower pivot structures 51B is greater than the distance B3 between the two upper pivot structures 51A, and is less than the width B1 of the waistband connecting side 36 of the child support 3 in the transverse direction, so that when the hip support portion 31 of the child support 3 is in a higher position to accommodate a smaller infant, the width of the seat area 101 effectively supported approaches the distance B2 between the two lower pivot structures 51B, to facilitate width adjustment.

[0193] The other structures and features of this embodiment are the same as those of the foregoing embodiments.

[0194] Furthermore, the applicant has noticed that when it is necessary to carry an infant out, the user will usually use an infant carrier to hold the infant on the body. The carrier mainly provides support to the hips of the infant through the seat area at the bottom thereof, thereby carrying the infant therein. The seat area of the carriers currently on the market often cannot be adjusted to different sizes of infants, or have relatively complex adjustment mechanisms and are inconvenient to use.

[0195] An embodiment of the present disclosure provides an infant carrier M100. Referring to FIGS. 29 and 30, FIGS. 29 and 30 respectively show schematic views of the infant carrier M100 in use from different angles.

[0196] As shown in FIG. 29, the infant carrier M100 comprises a carrying assembly M1A and a child support M3. The carrying assembly M1A comprises a waist belt M1 and a shoulder belt M2. The waist belt M1 extends generally in a transverse direction MD1 and is configured to be secured to a waist of a user in use. The shoulder belt M2 extends generally in a longitudinal direction MD2 and is configured to be looped around a shoulder of the user in use, forming a wearing loop M21. In an example, one end (i.e. a first end) of the shoulder belt M2 is connected to the waist belt M1. The child support M3 is connected to the waist belt M1 and the shoulder belt M2, forms a carrying space of the infant carrier M100 together with the shoulder belt M2, and supports (and encloses) an infant seated in the carrying space. Specifically, one end of the child support M3 is connected to the shoulder belt M2, for example, an upper end thereof is connected to an upper portion of the shoulder belt M2 (such as a position close to a top end of the shoulder of the user as shown in FIG. 29), while the other end (e.g. a lower end) of the child support M3 is connected to the waist belt M1. The child support M3 can also be connected to the waist belt M1 and / or the shoulder belt M2 at other positions, so as to enhance the supporting effect on the infant and the connection firmness between the waist belt M1 and / or the shoulder belt M2, and / or to make the overall structure of the infant carrier M100 more fit to the infant in the carrying space, and the present disclosure does not limit the specific connection. Optionally, for example, the lower end of the child support M3 is selectively connected to the waist belt M1 or the shoulder belt M2.

[0197] In an example, the upper end of the child support M3 is detachably connected to the shoulder belt M2, so as to facilitate the infant to get in and out of the carrying space. For example, the upper end of the child support M3 and a corresponding position on the shoulder belt M2 can be respectively provided with upper connection components detachably coupled to each other, such as a buckle structure, a magnetic buckle structure, a Velcro, a button structure, a hook-and-loop structure, etc.

[0198] It should be noted that the "upper", "lower", "longitudinal direction" and "transverse direction" described herein are the orientations of the infant carrier M100 in use, for example, the "longitudinal direction MD2" refers to the generally upward and downward direction or vertical direction of the infant carrier M100 in use, which can also be considered as the length direction of the infant carrier M100, while the "transverse direction MD1" is only the generally left and right direction of the infant carrier M100 in use, which can also be considered as the width direction of the infant carrier M100.

[0199] In addition, the child support M3 comprises a hip support portion M31 located at a lower portion of the child support M3 and a torso support portion M32 located above the hip support portion M31. Specifically, the hip support portion M31 and the torso support portion M32 are connected to each other, with an upper end of the torso support portion M32 constituting an upper end of the child support M3 and being connected to the shoulder strap M2, and a lower end of the torso support portion M32 being connected to an upper end of the hip support portion M31, and a lower end of the hip support portion M31 (i.e. an end away from the torso support portion M32) constituting a lower end of the child support M3 and being connected to the waist strap M1. In an example, the hip support portion M31 and the torso support portion M32 are non-detachably connected to each other. Alternatively, the hip support portion M31 and the torso support portion M32 form an integral structure, i.e. the child support M3 is a one-piece structure.

[0200] As shown in FIG. 30, the child support M3 is provided with a side extension M5 located between the upper end and the lower end of the child support M3. The side extension M5 is detachably or non-detachably connected to the child support M3, for example, to the torso support portion M32 or to the hip support portion M31 of the child support M3 near the torso support portion M32, and is configured such that at least a portion thereof extends outwardly from an outer edge M301 of the child support M3. In an example, the side extension M5 is connected to the child support M3 by means of sewing.

[0201] Alternatively, the side extension M5 is connected to the child support M3 at a position away from the outer edge M301 of the child support M3 in the transverse direction MD1, i.e. the side extension M5 is connected to the child support M3 at a position away from (or offset from) the outer edge M301 of the child support M3 in the transverse direction MD1. For example, the connection end M501 of the side extension M5 to the child support M3 is offset inwardly from the outer edge M301 of the child support M3, and the side extension M5 extends from an inner face of the child support M3 at the connection end M501 such that a portion of the side extension M5 (i.e. a portion thereof near the connection end M501 to the child support M3) can be obscured by the child support M3. It is noted that the “inner face” of the child support M3 (or the baby carrier M100) refers to a face that faces the user during use or a face that is proximate to the baby during use, and the “outer face” refers to a face opposite to the “inner face” or a face that faces outwardly during use.

[0202] Specifically, the child support M3 can have a flap, such as the side flap M302 shown in FIG. 30. The side flap M302 is located proximate to the outer edge M301 of the child support M3, and can be folded or rotated upward relative to other portions of the child support M3, such that a child upper limb avoidance space is formed between the side extension M5 and the side flap M302 of the child support M3, and in turn the child's upper limbs can move between the side extension M5 and the side flap M302 so as not to be excessively pressed against the user's body. For example, the side flap M302 can be formed as a portion of the child support M3 from the connection end M501 to the outer edge M301 in the substantially transverse direction MD1, or a portion of the child support M3 extending outward from the connection end M501.

[0203] Further, as shown in FIG. 30, one end (i.e., the first end) of the shoulder strap M2 is connected to the waist strap M1 or to a position of the child support M3 proximate to the waist strap M1, and the other end (i.e., the second end) is connected to the side extension M5. Optionally, the shoulder strap M2 and the side extension M5 are detachably connected, such as a snap structure, a magnetic buckle structure, a Velcro, a button structure, a hook-and-loop structure, etc.

[0204] Further, in combination with FIGS. 29 and 30, the child support M3 is further provided with a leg support M4 to support (or lift) the legs of the infant carried in the baby carrier M100. The leg support M4 is arranged to extend outward from the hip support portion M31 of the child support M3 in the transverse direction MD1. Specifically, at least a portion of the leg support M4 extends outward (i.e., in a direction away from the child support M3) from the outer edge M301 of the child support M3 in the transverse direction MD1. The hip support portion M31 and the leg support M4 form a seat region M101 for carrying the infant. In an example, two leg supports M4 can be provided, respectively arranged on both sides of the hip support portion M31 in the transverse direction MD1.

[0205] Further reference is made to FIGS. 31 and 32, which respectively show schematic views of the baby carrier M100 when unfolded from different angles. Specifically, FIG. 31 shows the inner face structure of the baby carrier M100, i.e., the structure proximate to the surface of the infant when in use, while FIG. 32 shows the outer face structure of the baby carrier M100, i.e., the structure facing outward when in use.

[0206] As shown in FIGS. 31 and 32, the leg support M4 is disposed between the waistband M1 and the side extension M5 along the longitudinal direction MD2. Specifically, the leg support M4 has a first connecting end M401 and a second connecting end M402 in the longitudinal direction MD2, the first connecting end M401 is connected to the waistband M1, and the second connecting end M402 is connected to the side extension M5. Optionally, the leg support M4 can be non-detachably connected to the waistband M1 and / or the side extension M5 by sewing or the like, i.e., the first connecting end M401 is non-detachably (and / or fixedly) connected to the waistband M1 and / or the second connecting end M402 is non-detachably (and / or fixedly) connected to the side extension M5, but the present disclosure is not limited to the above connection manner, for example, the leg support M4 and the waistband M1 and / or the side extension M5 can also be provided as detachable connection.

[0207] For example, FIGS. 33A and 33B show a variant example of the baby carrier M100, in which another connection manner between the leg support M4 and the side extension M5 is shown. Specifically, FIGS. 33A and 33B respectively show different states of the leg support M4 according to the variant example.

[0208] As shown in FIGS. 33A and 33B, the leg support M4 is detachably connected to the side extension M5. Specifically, the second connecting end M402 of the leg support M4 is provided with a first connecting piece M41, and the side extension M5 is correspondingly provided with a second connecting piece M51, the first connecting piece M41 and the second connecting piece M51 are detachably connected to each other. The first connecting piece M41 and the second connecting piece M51 can be a buckle structure, a magnetic buckle structure, a rivet and hole structure, a button and hole structure, a magic tape, a hook and loop structure, etc. which are detachably matched with each other, for example, the first connecting piece M41 is a button, and the second connecting piece M51 is a button hole.

[0209] In addition, the first connecting member M41 and the second connecting member M51 can also be pivotally connected to each other, so that the leg support member M4 is pivotally connected to the side extension member M5. In an example, the first connecting member M41 and the second connecting member M51 can be detachably and pivotally connected to each other. For example, the leg support member M4 shown in FIG. 33A can be pivoted to the position shown in FIG. 33A by the cooperation of the first connecting member M41 and the second connecting member M51, so that the leg support member M4 is unfolded outwardly relative to the hip support portion M3 to form a wider seat area M101. For example, when the infant is not seated in the infant carrier M100, the leg support member M4 is relatively close to the hip support portion M3, and when the infant is seated in the infant carrier M100, the seat area M101 is unfolded downwardly to form a pocket due to the weight of the infant, and the thighs of the infant press the leg support member M4 downwardly and outwardly, so that the leg support member M4 is unfolded outwardly relative to the hip support portion M3, thereby adaptively adjusting the seating width of the seat area M101, and the greater the weight of the infant, the greater the adaptive adjustment of the seating width of the seat area M101.

[0210] Alternatively or additionally, the connection between the leg support member M4 and the waist belt M1 or the position close to the waist belt M1 of the child support member M3 can also be provided as a detachable and / or pivotable connection. Through such a configuration, the first connecting end M401 of the leg support member M4 can be fixedly or pivotally connected to the waist belt M1 or the position close to the waist belt M1 of the child support member M3, and the second connecting end M402 of the leg support member M4 can be pivotally connected to the side extension member M5, thereby allowing the width adjustment of the leg support member M4, and further achieving the automatic adjustment of the seating width when the infant is seated in the carrying space. In other examples, the leg support member M4 can also be non-detachably but pivotally connected to the side extension member M5, which is not limited in the present disclosure.

[0211] In this example, as shown in FIGS. 33A and 33B, the leg support member M4 can be provided in a foldable or crumpleable structure. When the infant carrier M100 is not in use, the leg support member M4 is in a free state, at least partially folded as shown in FIG. 33A, and when the infant carrier M100 is in use, the leg support member M4 can be pivoted at the second connecting end M402 according to the leg weight of the infant and other factors, thereby causing the folded portion of the leg support member M4 to unfold appropriately, thereby achieving the automatic adjustment of the seating width.

[0212] For another example, FIG. 34 shows another variant example of the infant carrier M100, in which another connection manner between the leg support member M4 and the side extension member M5 is shown.

[0213] As shown in FIG. 34, the second connecting end M402 of the leg support M4 is provided with a first connecting piece M41, and the side extension piece M5 is provided with a plurality of second connecting pieces M51 (two second connecting pieces M51 are shown in the figure, but the present disclosure is not limited thereto, and more than two second connecting pieces M51 can also be provided). The first connecting piece M41 can be selectively connected with one of the plurality of second connecting pieces M51 to connect the second connecting end M402 of the leg support M4 to different positions on the side extension piece, so as to manually adjust the seating width of the seat area M101. In this way, the leg support M4 can be unfolded to different widths (i.e., different seating widths) relative to the child support M3, so as to better adapt to infants of different sizes. Optionally, the cooperation between the first connecting piece M41 and any second connecting piece M51 is a pivoting cooperation. For example, the first connecting piece M41 and the second connecting piece M51 are snap-fit or button-and-hole cooperation, etc. It can be understood that the first connecting piece M41 and the second connecting piece M51 can also be other cooperation modes, such as magnetic buckle structure, hook-and-loop structure, etc., as long as the manual adjustment of the seating width of the seat area M101 can be achieved.

[0214] It should be noted that the "detachable connection" and "non-detachable connection" as described above can be understood as limiting whether the connection between two elements is separable, while the "fixed connection" and "pivoting connection" can be understood as limiting whether the connection between two elements is relatively movable. For example, "fixed and detachable connection" can be understood as no relative movement (such as pivoting and sliding, etc.) between two elements, but the two can be separated and detached.

[0215] Referring back to FIGS. 30 and 31, the connecting end M501 of the side extension piece M5 and the child support M3 can be close to or located at the middle position of the child support M3 in the longitudinal direction MD2, so that the side extension piece M5 has a larger activity space relative to the connecting end M501, that is, the side extension piece M5 can have a greater degree of flexible adjustment, thereby making the second connecting end M402 connected with the side extension piece M5 more active, and further enabling the thigh support M4 to more freely conform to the leg contour of the infant, forming a flexible width support adjustment. At the same time, by connecting the side extension piece M5 to the middle position of the child support M3, a part of the support force of the seat area M101 can be distributed along the child support M3, and the gap between the side area of the child support M3 and the thigh support M4 can be increased, thereby facilitating the extension adjustment of the thigh support M4 in the transverse direction MD1 (i.e., the width direction). In addition, by connecting the side extension piece M5 to the middle position of the child support M3, an upper limb avoiding space can be formed between the side wing piece M302, so that the upper limbs of the infant can have a larger activity space, thereby improving the comfort of the infant.

[0216] Optionally, as shown in FIG. 31, a first opening M102 is formed on the lateral inner side of the first connecting end M401 of the leg support M4, for example, between the leg support M4, the waist belt M1 and the child support M3. Optionally or alternatively, a second opening M103 is formed on the lateral inner side of the second connecting end M402 of the leg support M4, for example, between the leg support M4, the side extension M5 and the child support M3. By providing the first opening M102 and / or the second opening M103, the adjustment space of the thigh support M4 can be further increased, and the ride comfort of the baby carrier M100 is further improved.

[0217] Further, as shown in FIG. 31, the hip support M31 is provided with a second connecting portion M312 at both sides in the lateral direction MD1, and optionally, the second connecting portion M312 is close to or located at the edge of the hip support M31 in the lateral direction MD1. The second connecting portion M312 is a linear structure between the first connecting end M401 and the second connecting end M402, or a linear structure between the side extension M5 and the waist belt M1. In addition, the leg support M4 is provided with a first connecting portion M44 at the side close to the hip support M31 in the lateral direction MD1, and optionally, the first connecting portion M44 is close to the inner edge of the leg support M4 in the lateral direction MD1 (i.e., close to the edge of the child support M3). The first connecting portion M44 is a linear structure between the first connecting end M401 and the second connecting end M402, or a linear structure between the side extension M5 and the waist belt M1.

[0218] In addition, optionally, in combination with FIGS. 30 and 31, a connecting member M43 is provided between the hip support M31 and the leg support M4, which allows the leg support M4 to move close to or away from the hip support M31 in the lateral direction MD1. The connecting member M43 is provided between the first connecting portion M44 and the second connecting portion M312. For example, the connecting member M43 is connected to the first connecting portion M44 and the second connecting portion M312 respectively at both sides in the lateral direction MD1.

[0219] In an example, the second connecting portion M312 of the hip support M31 is located inside the edge of the child support M3, similar to the side extension M5, the connecting member M43 is also connected to the hip support M31 at the inner side of the child support M3. In an example, the connecting end M501 of the side extension M5 and the second connecting portion M312 of the hip support M31 for connecting the connecting member M43 are substantially flush in the longitudinal direction MD2.

[0220] In an example, the connecting member M43 has a non-extended state (or contracted state) and an extended state (or expanded state) in the transverse direction MD1. The connecting member M43 is in the non-extended state when the infant carrier M100 is in the non-use state; and the connecting member M43 is in the extended state when the infant carrier M100 is in the use state. The degree of extension of the connecting member M43 can be adaptively adjusted according to the size (or weight) of the infant in the carrying space. When carrying an infant with a larger size (or weight), the connecting member M43 is in a larger degree of extension, such that the seat region M101 forms a deeper pocket structure and the dimension (i.e. width) in the transverse direction MD1 is increased to accommodate the infant with a larger size; and when carrying an infant with a smaller size (or weight), the connecting member M43 is in a smaller degree of extension, such that the seat region M101 forms a shallower pocket structure and the dimension in the transverse direction MD1 is relatively smaller to accommodate the infant with a smaller size, so as to allow the legs of the infant to form an ergonomic "M" shaped legs.

[0221] For example, the connecting member M43 can be made of an elastic material, so as to provide an elastic support to the seat region M101. When not in use, the elastic material is not under load and is in the non-extended state or contracted state (i.e. not stretched state); and when in use, the elastic material is under load and is stretched, thereby in the expanded state.

[0222] In an example, the connecting member M43 with the elastic material includes a first extension M431 and a second extension M432. For example, the first extension M431 and the second extension M432 can be formed by weaving linear materials. For another example, the first extension M431 and the second extension M432 are arranged alternately in a manner similar to the wave crests and wave troughs, such that the shape of the connecting member M43 is formed in a wave shape, thereby increasing the amount of elastic extension in the transverse direction. When the connecting member M43 is stretched in the transverse direction MD1, the first extension M431 and the second extension M432 are deformed to be flat and stretched in the transverse direction, thereby adaptively adjusted according to the size of the infant or the sitting posture (e.g. face-in or face-out) without the need of additional adjustment actions, thereby providing a carrying space with different widths.

[0223] In other examples, as schematically shown in FIG. 35, the connecting member M43 can be an elastic cloth with good ductility. When the connecting member M43 is stretched in the transverse direction MD1, the elastic cloth can be deformed to be stretched, thereby increasing the dimension in the transverse direction MD1, thereby adaptively adjusted according to the size of the infant or the sitting posture (e.g. face-in or face-out) without the need of additional adjustment actions, thereby providing a carrying space with different widths.

[0224] In this example, the first opening M102 can be provided between one end of the connecting member M43 in the longitudinal direction MD2 and the waist belt M1, the leg support M4 and the child support M3, and the second opening M103 can be provided between the other end of the connecting member M43 in the longitudinal direction MD2 and the side extension M5, the leg support M4 and the child support M3. The provision of the first opening M102 and the second opening M103 can make the adaptive adjustment of the connecting member M43 more convenient and flexible. In an example, the size of the first opening M102 is greater than the size of the second opening M103, so that when the infant is seated facing away from the user, the leg support M4 can be unfolded to a greater extent through the first opening M102, thereby facilitating more effective support of the legs and hips of the infant, while further increasing the adjustment space of the thigh support M4, improving the ride comfort of the baby carrier M100.

[0225] In an example, the hip support portion M31 can have a certain elasticity, so that when the baby carrier is used, the size of the hip support portion M31 in the longitudinal direction MD2 and / or the transverse direction MD1 can vary according to the weight or size of the infant. However, the present disclosure is not limited thereto, and the hip support portion M31 can also have other structures.

[0226] For example, with reference to FIGS. 36A to 36C, another variant example of the baby carrier M100 according to the present disclosure is shown. Specifically, FIGS. 36A to 36C show the structure of the hip support portion M31 according to another variant example, wherein FIGS. 36A and 36B show partial schematic views of the hip support portion M31 in a collapsed state and in an unfolded state, respectively, as viewed from the inner side, and FIG. 36C shows a partial schematic view of the hip support portion M31 in the unfolded state, as viewed from the outer side.

[0227] As shown in FIGS. 36A to 36C, the hip support portion M31 has a structure that can be collapsed in the transverse direction MD1. Specifically, when the baby carrier M100 is in a non-use state, the hip support portion M31 is in a collapsed state (see FIG. 36A); and when the baby carrier M100 is in a use state, the hip support portion M31 is in an unfolded state (see FIGS. 36B and 36C).

[0228] In this example, the hip support portion M31 can be connected with the leg support M4. For example, the second connecting portion M312 provided on both sides of the hip support portion M31 can be connected with the first connecting portion M44 provided on one side of the leg support M4.

[0229] Optionally, the lateral distance between the two sides of the hip support portion M31 and the connection points of the two leg support members M4 is less than the natural lateral width of the hip support portion M31 between the two connection points. For example, the lateral distance between the two first connection portions M44 of the two leg support members M4 is less than the natural lateral width of the two second connection portions M312 of the hip support portion M31. It is to be noted that the "natural lateral width" refers to the actual length of the fabric between the two side edges of the hip support portion M31 in the non-connected state (i.e. before being connected with the leg support members M4).

[0230] With such an arrangement, when the baby carrier is in the non-use state, the hip support portion M31 is in the crumpled state in the lateral direction MD1; and when the baby carrier is in the use state, i.e. the baby is seated in the baby carrier M100, the hip support portion M31 is in the unfolded state in the lateral direction MD1, and the degree of unfolding of the hip support portion M31 can be self-adaptively adjusted according to the size of the baby. Specifically, when a larger-sized baby is seated in the baby carrier M100, the baby can press down the seat area M101 by its own larger weight, so that the hip support portion M31 is pulled down and stretched to be in the unfolded state, the size of the seat area M101 in the longitudinal direction MD2 is larger, and due to the stretching deformation of the hip support portion M31, the weight of the baby exerts a larger force on the connection points between the two sides of the hip support portion M31 and the corresponding two leg support members M4, so that the hip support portion M31 is stretched to a larger extent in the lateral direction MD1 and has a larger degree of unfolding, the two leg support members M4 expand in the direction away from each other, and in combination with the hip support portion M31 being pressed and concave, the seat area M101 is increased, so as to be suitable for the larger-sized baby to be seated, and the legs of the baby can form the ergonomic M-shaped legs to improve the seating comfort. When a smaller-sized baby is seated in the baby carrier M100, due to the smaller gravity and smaller hip size of the baby, the hip support portion M31 is not pulled down too much, so that the hip support portion M31 is stretched to a smaller extent in the lateral direction MD1 and has a smaller degree of unfolding, the size of the seat area M101 in the longitudinal direction MD2 is smaller, and the weight of the baby exerts a smaller force F on the connection points between the two sides of the hip support portion M31 and the corresponding two leg support members M4, so that the hip support portion M31 has a smaller degree of unfolding in the lateral direction MD1, the two leg support members M4 are relatively close to each other, and the seat area M101 is reduced, so as to be suitable for the smaller-sized baby to be seated, and the legs of the baby can also form the ergonomic M-shaped legs to improve the seating comfort.

[0231] Thus, the baby carrier M100 of the present disclosure can adaptively adjust the seat region M101 formed by the hip support M31 and the leg support M4 according to the body size of the baby, and is simple in structure and convenient to use.

[0232] In other examples, the baby carrier M100 of the present disclosure can simultaneously provide the hip support M31 with a crumpled structure (as shown in FIGS. 36A-36C) and the connecting member M43 with an extendable structure (as shown in FIG. 31) so as to further increase the adjustable degree (i.e., the width) of the seat region M101.

[0233] Another embodiment of the present disclosure provides a baby carrier M100. The baby carrier M100 has a first mode and a second mode. When in the first mode, the baby carrier M100 is suitable for a larger-sized baby to ride; when in the second mode, the baby carrier M100 is suitable for a smaller-sized baby to ride. Referring to FIGS. 37 and 38, FIGS. 37 and 38 respectively show a schematic view of the baby carrier M100 in the first mode.

[0234] As shown in FIGS. 37 and 38, the baby carrier M100 includes a carrying assembly M1A and a child support M3. The child support M3 is detachably connected with the carrying assembly M1A, and forms a carrying space of the baby carrier M100 together with the carrying assembly M1A, and supports (and covers) a baby riding in the carrying space. Regarding the detachable connection between the child support M3 and the carrying assembly M1A, it will be described in detail later.

[0235] In an example, as shown in FIGS. 37 and 38, the carrying assembly M1A includes a waist belt M1, shoulder belts M2, and a chest support M9 (not labeled in FIG. 37, and can be referred to as shown in FIG. 38). The shoulder belts M2 extend generally along a longitudinal direction MD2, and can be wrapped around the shoulders of a user when in use, forming a wearing loop M21. As shown in FIG. 38, the shoulder belts M2 can be connected with the waist belt M1. The chest support M9 is disposed on the two shoulder belts M2, and is above the waist belt M1 in the longitudinal direction MD2. Specifically, a first end M201 of the shoulder belts M2 is connected with the waist belt M1, and a second end M202 of the shoulder belts M2 is directly or indirectly connected to the chest support M9 and / or the child support M3. That is: the second end M202 of the shoulder belts M2 is directly or indirectly connected to the chest support M9; or, the second end M202 of the shoulder belts M2 is directly or indirectly connected to the child support M3; or, the second end M202 of the shoulder belts M2 is directly or indirectly connected to the chest support M9 and the child support M3.

[0236] The second end M202 of the shoulder strap M2 is provided with a first connecting strap M22 and a second connecting strap M23, the first connecting strap M22 is connected to the chest support M9, and the second connecting strap M23 is connected to the child support M3. By connecting the shoulder strap M2 with the chest support M9 and the child support M3 respectively, the support strength of the baby carrier M100 to the baby can be enhanced. Among them, the first connecting strap M22 is non-detachably connected to the chest support M9. Optionally, the first connecting strap M22 is non-detachably connected with the chest support M9, for example, by sewing or the like, or forms an integral structure with the chest support M9. By non-detachable connection, the connection strength between the first connecting strap M22 and the chest support M9 can be enhanced. In other embodiments, the first connecting strap M22 can also be detachably connected with the chest support M9. In an example, the second connecting strap M23 is detachably connected to the substantially middle part of the child support M3 in the longitudinal direction MD2 through a support connecting component M25. Specifically, the support connecting component M25 is, for example, a buckle structure, a magnetic buckle structure, a Velcro, a button structure, a hook and loop structure, etc. which are detachably matched at the corresponding positions of the child support M3 and the second connecting strap M23 respectively.

[0237] Optionally or alternatively, the second end M202 of the shoulder strap M2 can be provided only with the first connecting strap M22 and connected with the chest support M9 through the first connecting strap M22; or, the second end M202 of the shoulder strap M2 is provided only with the second connecting strap M23, and the second connecting strap M23 is detachably connected to the substantially middle part of the child support M3 in the longitudinal direction MD2 through the support connecting component M25; or, the second end M202 of the shoulder strap M2 is detachably connected to the substantially middle part of the child support M3 in the longitudinal direction MD2 through the support connecting component M25.

[0238] In an example, as shown in FIGS. 37 and 38, the child support M3 includes a hip support portion M31 and a torso support portion M32, the hip support portion M31 is located at the lower part of the child support M3 in use, and the torso support portion M32 is located above the hip support portion M31. The hip support portion M31 constitutes at least part of the seat area M101 of the baby carrier M100. The specific structure of the hip support portion M31 and the torso support portion M32 can refer to the structure in the example shown in FIGS. 29 to 36C, which will not be described here.

[0239] Optionally, referring to FIGS. 37, 38 and 42, the child support M3 is provided with leg supports M4 for supporting or lifting the legs of an infant carried in the baby harness M100. Optionally, the child support M3 is provided with two leg supports M4, which are respectively arranged on both sides of the hip support portion M31 in the transverse direction MD1. The hip support portion M31 and the leg supports M4 form a seat area M101 for carrying an infant. Each leg support M4 has a first connecting end M401 and a second connecting end M402 in the longitudinal direction MD2. The differences between the leg supports M4 in the present example and the leg supports M4 in the example shown in FIGS. 29-36C will be described in detail below, and the same parts of the leg supports M4 in the present example and the leg supports M4 in the example shown in FIGS. 29-36C will not be described again.

[0240] In an example, as shown in FIG. 38, the first connecting end M401 of the leg support portion M4 is connected to the lower end of the child support M3 and / or the waist belt M1, and the second connecting end M402 is detachably connected to the substantially middle portion of the child support M3 in the longitudinal direction MD2. In an example, the first connecting end M401 of the leg support portion M4 is connected to the lower end of the child support M3, and the lower end of the child support M3 is detachably connected to the waist belt M1. Optionally, in other examples, the first connecting end M401 of the leg support portion M4 is detachably connected to the waist belt M1; or, the first connecting end M401 of the leg support portion M4 is connected to the child support M3 without being directly connected to the waist belt M1.

[0241] As shown in FIG. 38 and FIG. 42, the second connecting end M402 of the leg support M4 is provided with a first connecting member M41, and the child support M3 is provided with a second connecting member M51 located at the approximate middle of the child support in the longitudinal direction MD2 and near the support connecting member M25. The first connecting member M41 and the second connecting member M51 are connected to each other. The portions of the first connecting member M41 and the second connecting member M51 used for cooperation with each other are located on the sides of the leg support M4 and the child support M3 facing each other, respectively. The first connecting member M41 and the second connecting member M51 are, for example, rivet buckle structures that can be buckled to each other, so that the leg support M4 can be pivotally connected to the child support M3 through the second connecting end M402 to facilitate adjustment of the sitting width of the infant. It can be understood that the first connecting member M41 and the second connecting member M51 can also be buckle structures, magnetic buckle structures, button and hole structures, Velcro, hook and loop structures, etc. that can be detachably cooperated with each other. Through the cooperation of the first connecting member M41 and the second connecting member M51, the second connecting end M402 of the leg support M4 can be connected to the approximate middle region of the child support M3, so that the first connecting belt M22 can be used to improve the supporting effect of the leg support M4 on the legs of the infant, and the width of the seat region M101 can be adjusted. In an embodiment, the first connecting member M41 and the second connecting member M51 can be detachably and pivotally connected to each other, so that the leg support M4 can be pivotally connected to the first connecting belt M22. Through the pivotal connection between the first connecting member M41 and the second connecting member M51, the leg support M4 can be unfolded outward relative to the hip support M3 to form a wider seat region M101, so as to adaptively adjust the sitting width of the infant according to the weight of the infant.

[0242] In other examples, the leg support M4 can be connected to the approximate middle region of the child support M3 in another way. For example, the second connecting end M402 of the leg support M4 is provided with a first connecting member M41, and the child support M3 is provided with a plurality of second connecting members M51, such as two, three, four or more second connecting members M51. The specific connection mode between the first connecting member M41 and the plurality of second connecting members M51 can refer to the related description of the first connecting member M41 and the plurality of second connecting members M51 in the example shown in FIG. 34 above, which will not be described here.

[0243] Optionally, a connecting member M43 is provided between the leg support M4 and the hip support M31. The specific structure of the connecting member M43 can refer to the description in the example shown in FIG. 30 and FIG. 31, which will not be described here.

[0244] Optionally, the hip support portion M31 has a structure capable of being crumpled in the transverse direction MD1. The specific arrangement of the crumpled structure can be referred to the description in the examples shown in Figs. 36A-36C, which will not be repeated here.

[0245] Referring back to Figs. 37 and 38, the upper end of the child support M3 is detachably connected with the carrying assembly M1A to facilitate the ingress and egress of the infant into the carrying space. Specifically, the upper end of the child support M3 is detachably connected to the shoulder strap M2, for example, via the upper connecting member M7. The detachable connection between the upper end of the child support M3 and the shoulder strap M2 can be referred to the description in the examples shown in Figs. 29-36C, which will not be repeated here.

[0246] Referring to Fig. 38, the infant carrier M100 further comprises two leg limiting assemblies M8 extending between the carrying assembly M1A and the child support M3 and disposed on the left and right sides proximate to the two leg support members M4, respectively. Each leg limiting assembly M8 and its ipsilateral leg support member M4 can at least partially define an adjustable limiting opening through which the legs of the infant can be positioned, wherein each leg limiting assembly M8 extends above its ipsilateral leg support member M4. In this way, the leg limiting assemblies M8 can position the infant and prevent the infant from falling off the side of the infant carrier M100 when the infant is seated in the infant carrier M100. It can be appreciated that in embodiments in which the leg support members are not provided, each leg limiting assembly M8 can also at least partially define an adjustable limiting opening with the child support M3 through which the legs of the infant can be positioned.

[0247] Each leg limiting assembly M8 comprises a limiting member M81 extending between the child support M3 and the carrying assembly M1A. The limiting member M81 has an elongated shape. One end (i.e., the fixed end portion M811) of the limiting member M81 is fixedly connected to one of the child support M3 and the carrying assembly M1A, and the other end (i.e., the connecting end portion M812) of the limiting member M81 is detachably connected to the other of the child support M3 and the carrying assembly M1A. For example, as shown in Fig. 38, in the present example, the fixed end portion M811 of the limiting member M81 is connected to the torso support portion M32 of the child support M3, and the connecting end portion of the limiting member M81 is configured to be detachably connected to the carrying assembly M1A.

[0248] In the present example, each leg limiting assembly M8 further comprises a first cooperating member M82 and a second cooperating member M83. The first cooperating member M82 is provided on the limiting member M81 at the connecting end portion M812 thereof, and the second cooperating member M83 is provided on the chest panel M91. The first cooperating member M82 and the second cooperating member M83 are detachably cooperable with each other to detachably connect the connecting end portion M812 of the limiting member M81 to the chest panel M91. The first cooperating member M82 is for example a button hole, and the second cooperating member M83 is for example a button. Vice versa. It is appreciated that the first cooperating member M82 and the second cooperating member M83 can also be a snap structure, a magnetic structure, a button and hole structure, a Velcro, a hook and loop structure, etc. detachably cooperable with each other.

[0249] Optionally, in each leg limiting assembly M8, the first cooperating member M82 can be provided as one or more. The second cooperating member M83 can also be provided as one or more, at least one of the second cooperating member M83 being provided on the first connecting strap M22. In the present example, the fixed end portion M811 of the limiting member M81 is connected to the child support M3 by sewing.

[0250] It is appreciated that in other embodiments, the second cooperating member M83 can also be provided on other locations of the carrying assembly M1A, for example on the first connecting strap M22 of the shoulder strap M2 (as shown in Figures 43 and 44), without being limited to the present disclosure.

[0251] Alternatively, the fixed end portion M811 of the limiting member M81 is connected to the carrying assembly M1A, for example to the chest panel M91, and the connecting end portion M812 of the limiting member M81 is detachably connected to the torso support portion M32 of the child support M3. Specifically, the first cooperating member M82 is provided on the connecting end portion M812, and the second cooperating member M83 is provided on the child support M3, for example at a substantially middle portion of the child support M3 in the longitudinal direction MD2, so as to detachably connect the connecting end portion M812 of the limiting member M81 to the child support M3.

[0252] Referring to Figs. 38, 41 and 42, the lower portion of the child support M3 is detachably connected with the back-carrying assembly M1A by a lower connecting member M6. The lower connecting member M6 comprises a plurality of adjustment connecting portions M61 and a plurality of adjustment cooperating portions M62. One of the lower portion of the child support M3 and the back-carrying assembly M1A is provided with the plurality of adjustment connecting portions M61, and the other of the lower portion of the child support M3 and the back-carrying assembly M1A is provided with the plurality of adjustment cooperating portions M62. It is to be noted that the "plurality" in the present application means two or more. The plurality of adjustment connecting portions M61 are different in width in the transverse direction MD1 and in height in the longitudinal direction MD2. The plurality of adjustment cooperating portions M62 are different in width in the transverse direction MD1, and are selectively detachably connected with the plurality of adjustment connecting portions M61. Optionally, the number of the adjustment connecting portions M61 is set to be at least two, for example, two, three, four, etc., and the number of the adjustment cooperating portions M62 is correspondingly set to be at least two, for example, two, three, four, etc. The number of the adjustment cooperating portions M62 is equal to the number of the adjustment connecting portions M61. The plurality of adjustment connecting portions M61 or the plurality of adjustment cooperating portions M62 provided on the back-carrying assembly M1A are located below the upper connecting member M7 in the longitudinal direction MD2. For infants of different sizes, by selectively connecting at least one of the plurality of adjustment cooperating portions M62 with a corresponding adjustment connecting portion M61, the height of the connecting portion between the child support M3 and the back-carrying assembly M1A in the longitudinal direction MD2 and the size (i.e. the width) of the connecting portion in the transverse direction MD1 can be changed, so as to adjust the height of the hip support portion M31 in the longitudinal direction MD2 and the size in the transverse direction MD1. In this way, for infants of different sizes, the height in the longitudinal direction MD2 and the width in the transverse direction MD1 of the seat region M101 (see Fig. 37) can be adjusted simultaneously, i.e. the sitting height and the sitting width of the infant can be adjusted simultaneously.

[0253] The plurality of adjustment connecting portions M61 includes a first adjustment connecting portion M611 having a lowest height in the longitudinal direction MD2 and a second adjustment connecting portion M612 having a highest height in the longitudinal direction MD2. The size of the first adjustment connecting portion M611 in the transverse direction MD1 (i.e. the width MW1 of the first adjustment connecting portion M611) is greater than the size of the second adjustment connecting portion M612 in the transverse direction MD1 (i.e. the width MW2 of the second adjustment connecting portion M612). Correspondingly, the plurality of adjustment engaging portions M62 includes a first adjustment engaging portion M621 and a second adjustment engaging portion M622. The size of the first adjustment engaging portion M621 in the transverse direction MD1 (i.e. the width ML1 of the first adjustment engaging portion M621) is greater than the size of the second adjustment engaging portion M622 in the transverse direction MD1 (i.e. the width ML2 of the second adjustment engaging portion M622), and ML1 = MW1 > MW2 = ML2. The first adjustment engaging portion M621 is detachably connected with the first adjustment connecting portion M611, and the second adjustment engaging portion M622 is detachably connected with the second adjustment connecting portion M612.

[0254] Referring to FIGS. 38 and 39, when the first adjustment connecting portion M611 is connected with the first adjustment engaging portion M621, the baby carrier M100 is in the first mode, the connecting portion between the child support M3 and the carrying assembly M1A has a greater width and a lower height in the longitudinal direction MD2, so that the seat region M101 capable of providing effective support (see FIG. 37) has a lower height in the longitudinal direction MD2 and a greater size (i.e. the seating width of the seat region M101) in the transverse direction MD1, which is suitable for a baby with a relatively larger body size.

[0255] Referring to FIG. 40A, when the second adjustment connecting portion M612 is connected with the second adjustment engaging portion M622, the baby carrier M100 is in the second mode, the connecting portion between the child support M3 and the carrying assembly M1A has a smaller width and a higher height in the longitudinal direction MD2. The lower portion of the child support M3 is not connected with the carrying assembly M1A near the outer edge M301 (not shown in FIG. 40A, see FIG. 42), and thus cannot provide support, so that the seat region M101 capable of providing effective support has a higher height in the longitudinal direction MD2 and a smaller seating width, which is suitable for a baby with a relatively smaller body size. By selecting the adjustment connecting portion M61 having a different height in the longitudinal direction MD2 and the corresponding adjustment engaging portion M62 to be connected, the seating width of the seat region M101 (see FIG. 37) and its height in the longitudinal direction MD2 can be effectively adjusted, so that the baby carrier M100 can be adapted to babies with different body sizes.

[0256] In an example, as shown in FIGS. 41 and 42, the backpack assembly M1A is provided with a plurality of adjustment connecting portions M61, and the lower portion of the child support M3 is provided with a plurality of adjustment cooperating portions M62. As the height of the plurality of adjustment connecting portions M61 in the longitudinal direction MD2 increases, the size of the plurality of adjustment connecting portions M61 in the lateral direction MD1 (i.e. the width of the adjustment connecting portions M61) decreases. That is, the higher the height of each adjustment connecting portion in the longitudinal direction MD2, the smaller the width of the adjustment connecting portion M61.

[0257] Specifically, as shown in FIGS. 38-40A, the plurality of adjustment connecting portions M61 includes a first adjustment connecting portion M611 provided on the waist belt M1 and a second adjustment connecting portion M612 provided on the chest support M9. The plurality of adjustment cooperating portions M62 includes a first adjustment cooperating portion M621 and a second adjustment cooperating portion M622, the first adjustment cooperating portion M621 is detachably connected with the first adjustment connecting portion M611, and the second adjustment cooperating portion M622 is detachably connected with the second adjustment connecting portion M612. The width MW1 of the first adjustment connecting portion M611 is greater than the width MW2 of the second adjustment connecting portion M612, the width ML1 of the first adjustment cooperating portion M621 is greater than the width ML2 of the second adjustment cooperating portion M622, and MW1 = ML1 > ML2 = MW2. In an example, the first adjustment cooperating portion M621 and the second adjustment cooperating portion M622 are both provided at the lower end of the child support M3, i.e. the height of the first adjustment cooperating portion M621 and the second adjustment cooperating portion M622 in the longitudinal direction MD2 can be considered to be substantially the same. In this way, it is convenient to connect the first adjustment cooperating portion M621 or the second adjustment cooperating portion M622 with the corresponding first adjustment connecting portion M611 or the second adjustment connecting portion M612, thereby facilitating adjustment of the seating width of the seat region 101 and its height in the longitudinal direction MD2.

[0258] In other embodiments not shown, the positions of the first adjustment connecting portion M611 and the second adjustment connecting portion M612 can be changed. For example: the first adjustment connecting portion M611 is provided on the waist belt M1, the second adjustment connecting portion M612 is provided on the shoulder belt M2 and is located above the first adjustment connecting portion M611 in the longitudinal direction MD2; or, the second adjustment connecting portion M612 is provided on the chest support M9, and the first adjustment connecting portion M611 is provided on the shoulder belt M2 below the chest support M9 in the longitudinal direction MD2 and is located below the second adjustment connecting portion M612; or, the first adjustment connecting portion M611 is provided on the shoulder belt M2, and the second adjustment connecting portion M612 is also provided on the shoulder belt M2 and is located above the first adjustment connecting portion M611 in the longitudinal direction MD2.

[0259] As shown in FIGS. 41 and 42, in an example, the adjustment connecting part M61 and the adjustment mating part M62 are, for example, a zipper which is detachably mateable with each other, in particular, a zipper which is a slide fastener. It can be understood that the adjustment connecting part and the adjustment mating part M62 can also be a snap structure, a magnetic buckle structure, a Velcro, a rivet and hole structure, a button and hole structure, a hook and loop structure, etc. which are detachably mateable with each other, and the present disclosure is not limited thereto.

[0260] As shown in FIGS. 39-40B, the chest support M9 includes a chest panel M91 and a wing panel M92. The chest panel M91 is connected to the shoulder strap M2 and extends in the transverse direction MD1. One side of the wing panel M92 is connected to the chest panel M91, so that the wing panel M92 can be flipped or rotated up and down relative to the chest panel M91. Among them, when the wing panel M92 is flipped or rotated downward, the wing panel M92 can cover at least the second adjustment connecting part M612, as shown in FIG. 40B. When the wing panel M92 is flipped or rotated upward, the second adjustment connecting part M612 can be exposed to facilitate connection with the second adjustment mating part M622, as shown in FIG. 40A. Therefore, when the baby carrier M100 is used in the second mode, the second adjustment connecting part M612 is connected with the second adjustment mating part M622, and the wing panel M92 is flipped downward, which can shield the connection site of the second adjustment connecting part M612 and the second adjustment mating part M622. In this way, on the one hand, it avoids the second adjustment connecting part M612 and the second adjustment mating part M622 directly contacting the baby sitting in the carrying space of the baby carrier M100, and on the other hand, it makes the baby carrier M100 more beautiful. Optionally, the size of the wing panel M92 in the transverse direction MD1 (i.e., the width MS of the wing panel) is greater than the width MW2 of the second adjustment connecting part M612, and is greater than or equal to the width ML1 of the first adjustment mating part M621. In this way, as shown in FIG. 40B, when the wing panel M92 is flipped downward, the wing panel M92 can also cover the first adjustment mating part M621.

[0261] FIG. 43 shows a schematic view of a carrying assembly of a baby carrier according to a variant example of the present disclosure.

[0262] Referring to FIG. 43, the shoulder strap M2 is provided with a plurality of sets of first adjustment members M24 arranged in sequence in the longitudinal direction MD2, and the chest support M9 is provided with a second adjustment member M93 selectively connected with one of the sets of first adjustment members M24 to adjust the height of the chest support M9 in the longitudinal direction MD2, i.e. the chest support M9 is vertically displaceable (or slidable) in the longitudinal direction MD2 so as to adjust the height of the second adjustment connecting portion M612 provided on the chest support M9 in the longitudinal direction MD2, so as to more flexibly adjust the connecting height of the child support M3 and thus the ride height of the infant. By selectively connecting the second adjustment member M93 with one of the sets of first adjustment members M24, the chest support M9 is vertically displaceable in the longitudinal direction MD2, so as to further adjust the height of the seat region M101. Optionally, any one of the sets of first adjustment members M24 and the corresponding second adjustment member M93 are, for example, detachably cooperating buckle structures, button and hole structures, hook and loop structures, etc. Exemplarily, as shown in FIG. 43, one of the sets of first adjustment members M24 is, for example, a row of button holes, and the corresponding second adjustment member M93 is, for example, a row of buttons; or vice versa.

[0263] In other embodiments not shown, the chest support M9 is kept at a fixed height, and the second adjustment connecting portion M612 is slidably provided on the shoulder strap M2 and can be connected at different heights by combining with the first adjustment members M24.

[0264] FIGS. 44-45 show another variant example of the infant carrier M100, wherein FIG. 44 shows a schematic view of the carrying assembly M1A in the variant example, and FIG. 45 shows a schematic view of the child support M3 in the variant example.

[0265] Referring to Figs. 44 and 45, this modification example differs from the example shown in Figs. 38 to 42 in that the heights of the plurality of adjustment fitting portions M62 in the longitudinal direction MD2 are also different. Specifically, as the heights of the plurality of adjustment fitting portions M62 in the longitudinal direction MD2 increase, the sizes of the plurality of adjustment fitting portions M62 in the lateral direction MD1 decrease. That is, the higher the height of each adjustment fitting portion M62 in the longitudinal direction MD2, the smaller the width of the adjustment fitting portion M62 in the lateral direction MD1. More specifically, the plurality of adjustment fitting portions M62 include, for example, a first adjustment fitting portion M621 and a second adjustment fitting portion M622, the second adjustment fitting portion M622 being positioned above the first adjustment fitting portion M621 in the longitudinal direction MD2, and the width ML2 of the second adjustment fitting portion M622 being smaller than the width ML1 of the first adjustment fitting portion M621. Since the heights of the adjustment fitting portions M62 in the longitudinal direction MD2 are also different, the seating height of the infant can be adjusted more effectively. That is, when the second adjustment fitting portion M622 positioned in the upper portion in the embodiment shown in Fig. 45 is connected to the second adjustment connecting portion M612 positioned in the upper portion shown in Fig. 44, the seating height of the infant is further increased as compared to the embodiment shown in Fig. 42.

[0266] Figs. 46 and 47 show still another modification example of the baby carrier M100, in which Fig. 46 shows a schematic view of the baby-carrying assembly M1A in this modification example, and Fig. 47 shows a schematic view of the child support M3 in this modification example.

[0267] Referring to FIGS. 46 and 47, the number of the plurality of adjustment connecting portions M61 can be greater than two (three adjustment connecting portions M61 are shown in the figures, but the present disclosure is not limited thereto, and more than three adjustment connecting portions M61 can also be provided). Accordingly, the number of the plurality of adjustment fitting portions M62 is greater than two and equal to the number of the plurality of adjustment connecting portions M61. Specifically, the plurality of adjustment connecting portions M61 includes a third adjustment connecting portion M613 in addition to the first adjustment connecting portion M611 and the second adjustment connecting portion M612. Accordingly, the plurality of adjustment fitting portions M62 includes a third adjustment fitting portion M623 in addition to the first adjustment fitting portion M621 and the second adjustment fitting portion M622, and the third adjustment fitting portion M623 is detachably connected with the third adjustment connecting portion M613. Among them, the third adjustment connecting portion M613 is located between the first adjustment connecting portion M611 and the second adjustment connecting portion M612 in the longitudinal direction MD2, and the size of the third adjustment connecting portion M613 in the transverse direction MD1 (i.e., the width MW3 of the third adjustment connecting portion M613) is less than the width MW1 of the first adjustment connecting portion M611 and greater than the width MW2 of the second adjustment connecting portion M612, i.e., MW1>MW3>MW2. The size of the third adjustment fitting portion M623 in the transverse direction MD1 (i.e., the width ML3 of the third adjustment fitting portion M623) is less than the width ML1 of the first adjustment fitting portion M621 and greater than the width ML2 of the second adjustment fitting portion M622, i.e., ML1>ML3>ML2. Since the number of the adjustment connecting portions M61 and the adjustment fitting portions M62 is set to three, the sitting height and width of the infant can be adjusted more flexibly and effectively.

[0268] FIGS. 48 and 49 show another variant example of the infant carrier M100. Among them, FIG. 48 shows a schematic view of the carrying assembly M1A in the variant example, and FIG. 49 shows a schematic view of the child support M3 in the variant example.

[0269] The difference between the variant shown in FIGS. 48 and 49 and the example shown in FIGS. 38 to 42 is that the positions of the plurality of adjustment connecting portions M61 and the plurality of adjustment fitting portions M62 are different. In this example, the lower portion of the child support M3 is provided with a plurality of adjustment connecting portions M61 (two adjustment connecting portions are shown in the drawings, but the present disclosure is not limited thereto, and more than two adjustment connecting portions can be provided), and the backpack assembly M1A is provided with a plurality of adjustment fitting portions M62. The plurality of adjustment connecting portions M61 increase in height in the longitudinal direction MD2 and decrease in size in the lateral direction MD1. That is, the higher the height of each adjustment connecting portion in the longitudinal direction MD2, the smaller the width. The plurality of adjustment fitting portions M62 are different at least in width. The plurality of adjustment fitting portions M62 can be substantially the same in height in the longitudinal direction MD2, but different in size in the lateral direction MD1. For example, as shown in FIG. 48, the plurality of adjustment fitting portions M62 are all provided on the chest support M9. Alternatively, the plurality of adjustment fitting portions M62 can all be provided on the waist belt M1 or the shoulder belt M2. For a larger infant, the lower adjustment connecting portion M61 (e.g., the first adjustment connecting portion M611) in the longitudinal direction MD2 can be connected to the corresponding adjustment fitting portion M62 (e.g., the first adjustment fitting portion M621), so that the seat region M101 has a larger width and a lower height in the longitudinal direction MD2. For a smaller infant, one of the higher adjustment connecting portions M61 (e.g., the second adjustment connecting portion M612) in the longitudinal direction MD2 can be connected to the corresponding adjustment fitting portion M62 (e.g., the second adjustment fitting portion M622), so that the seat region M101 has a higher height in the longitudinal direction MD2 and a smaller width in the lateral direction MD1. In this way, the overall structure of the baby carrier M100 can better fit the infant in the carrying space.

[0270] In other embodiments not shown, the baby carrier M100 can be provided with both the side extensions M5 of any of the embodiments shown in FIGS. 29-36C and the adjustment connecting portions M61 and the adjustment fitting portions M62 of any of the embodiments shown in FIGS. 37-49.

[0271] FIGS. 50 to 53 show schematic views of one variant of the baby carrier M100 according to the present disclosure, in which FIGS. 50 and 51 do not carry an infant, and FIGS. 52 and 53 carry an infant.

[0272] As shown in FIGS. 50 to 55, the lateral sides of the child support M3 extend longitudinally to form two connecting belts N33, each of which is provided with a connecting member for connecting to the upper portion of the shoulder belt M2, so as to connect the upper end of the child support M3 to the upper portion of the shoulder belt M2.

[0273] Referring to FIGS. 50 and 51, the upper portion of the torso support portion M32 is provided with a headrest portion N6 for supporting the head of the infant, and is made of a bendable soft material. The headrest portion N6 is connected to the torso support portion M32 between the two shoulder straps M2 in the transverse direction MD1, for example, by a connecting portion N601. The headrest portion N6 can be flipped up and down about the connecting portion N601. The connecting portion N601 can be provided as a sewn line, for example.

[0274] In this example, the two connecting bands N33 are each provided with a third connecting member N202. The upper portion of the headrest portion N6 in the longitudinal direction MD2 is provided with two fourth connecting members N602, which are provided on both sides of the headrest portion N6 in the transverse direction. The fourth connecting members N602 are configured to engage with the third connecting members N202.

[0275] Optionally, the third connecting members N202 are buckling bands, and the fourth connecting members N602 are connecting buckles, for example. One end of the third connecting member N202 is fixedly connected to the shoulder strap M2, and the other end is provided with a connecting opening for buckling with the connecting buckle. In other embodiments, the third connecting members N202 can be connecting buckles, and the fourth connecting members N602 can be buckling bands.

[0276] Optionally, in the case where the third connecting members N202 are buckling bands, the connecting bands N33 are provided with accommodating portions N201 in which the third connecting members N202 can be accommodated, for the convenience of accommodating the third connecting members N202. One end of the third connecting member N202 is fixed to the inside or edge of the accommodating portion N201, so that the third connecting member N202 can be accommodated in the accommodating portion N201 as a whole after being unbuckled from the connecting buckle. The accommodating portion N201 can be formed on the surface of the connecting band N33 in the same direction as the extension direction of the connecting band N33, and can be formed as a pocket, for example.

[0277] Alternatively, in the case where the fourth connecting members N602 are buckling bands, the headrest portion N6 is provided with accommodating portions in which the fourth connecting members N602 can be accommodated. One end of the fourth connecting member N602 is fixed to the inside or edge of the accommodating portion, so that the fourth connecting member N602 can be accommodated in the accommodating portion as a whole after being unbuckled from the connecting buckle.

[0278] According to the present embodiment, the third connecting member N202 is provided as an elastic connecting member (for example, an elastic band), which can be self-adaptively adjusted in length by an external force. In other embodiments, the third connecting member N202 can also be other elastic connecting members, as long as it can be self-adaptively adjusted in length by an external force. In other embodiments, the fourth connecting member N602 can also be provided as an elastic connecting member which can be self-adaptively adjusted in length by an external force. As shown in FIG. 52, when the infant is carried and faces the carrier, the headrest N6 is converted from the initial position in FIG. 51 to the unfolded position in FIG. 52, because the headrest N6 abuts against the head of the infant. When the infant of different sizes is seated in the baby carrier M100, the elastic band is self-elongated to the appropriate position, which is suitable for the size of the infant's head.

[0279] As shown in FIG. 53, when the headrest N6 is not needed (for example, the infant faces forward), the third connecting member N202 and the fourth connecting member N602 can be disconnected, and the headrest N6 can be folded downward around the connecting portion N601. In this case, the third connecting member N202 can be accommodated inside the accommodating portion N201 after being disconnected from the headrest N6, so as to keep the appearance neat and tidy and facilitate operation and accommodation.

[0280] FIGS. 54, 55 and 56 show schematic views of yet another variant example of the baby carrier M100 according to the present disclosure. As shown in FIG. 54, the headrest N6 is folded downward from the position of the connecting portion N601 as shown in FIG. 53. In FIG. 55, the headrest N6 is folded upward from the position of the connecting portion N601.

[0281] A cover N603 is provided on the inner side of the headrest N6, which is connected to the inner side of the headrest N6 along the transverse direction, one end of the cover N603 is connected to the headrest N6, and the other end is provided with connecting members on the left and right sides to be connected to the shoulder strap M2 or to each other behind the neck of the user, so as to keep the cover N603 unfolded. The cover N603 extends upward along the longitudinal direction MD2 to cover the head of the infant, so as to avoid, for example, direct sunlight. The cover N603 can be a breathable material such as a mesh cloth.

[0282] When the headrest N6 is needed to support the head of the infant, the headrest N6 is folded upward from the position of the connecting portion N601 as shown in FIG. 55, so as to partially block the cover N603. The headrest N6 can be connected to the connecting strap N33 by the third connecting member N202 and the fourth connecting member N602, and the specific connection manner can be referred to the description of FIGS. 50, 51 and 52.

[0283] According to the present disclosure, in the upper portion of the headrest N6 along the longitudinal direction MD2, a receiving portion N604 is arranged on the inner side of the headrest N6, which is used to accommodate the cover N603 when it is not needed, as shown in FIG. 56, the cover N603 is stored in the receiving portion N604. One end of the cover N603 is fixed to the inside or edge of the receiving portion N604, and when the cover N603 is not used, it can be folded and accommodated in the receiving portion N604. The opening of the receiving portion N604 is close to or formed at the position of the connecting portion N601, and the end of the cover N603 can be fixed to the opening of the receiving portion N604. The cover N603 is arranged on the inner side of the headrest N6, which is convenient for different modes of use, that is, the cover N603 can be normally and conveniently used when the headrest N6 is in the unfolded state or the folded state, and the whole is beautiful.

[0284] In addition, in the case of no conflict in structure, the plurality of embodiments or examples as described above in the present disclosure can be used in combination with each other, which is not described here.

[0285] FIGS. 57, 58, 59 and 60 show a baby carrier according to another embodiment, which is similar to the embodiment of FIG. 14, and the difference is that the elastic member R62 in this embodiment is slightly different from the elastic member 52 shown in FIG. 14. FIGS. 59 and 60 are end side views of the elastic connecting member R62 shown in FIG. 57. The following is to avoid repetition, only the differences relative to FIG. 14 are described.

[0286] According to the present embodiment, the elastic member R62 is connected between the hip support portion 31 and the leg support member 51, and in the unloaded state or non-use state, the elastic member R62 is crumpled together, and in the loaded state or use state, the elastic member R62 is stretched apart. The elastic member R62 forms a first opening 102 between the waistband 1, the hip support portion 31 and the leg support member 51 on one end side in the longitudinal direction, and forms a second opening 103 between the torso support portion 32, the hip support portion 31 and the leg support member 51 on the other end side. According to the present embodiment, the size of the first opening 102 is larger than that of the second opening 103, so that when the baby is riding away from the mother, the leg support member 51 can be unfolded more through the first opening 102, which is beneficial to effectively support the baby's hips and legs.

[0287] Referring to the end side views of FIGS. 59 and 60, the elastic member R62 has a plurality of first extension portions R621 and second extension portions R622 parallel to each other, wherein the first extension portions R621 and the second extension portions R622 are arranged alternately in a manner similar to wave crests and wave troughs, so that the shape of the elastic member R62 is formed in a wave shape, thereby increasing the amount of elastic extension of the elastic member R62 in the lateral direction. FIG. 59 schematically shows that the rib-shaped top ends of the first extension portions R621 and the second extension portions R622 are in the shape of an angle. As shown in FIG. 60, the rib-shaped top ends of the first extension portions R621 and the second extension portions R622 can also be in the shape of an arc.

[0288] According to the present disclosure, the elastic member R62 is a material that is elastically stretchable in the lateral direction, has softness, and has lateral stretchability. In the present embodiment, the elastic member R62 is formed of a stretch fabric that is more stretchable in the width direction than in the length direction, in other words, the elastic member R62 is more stretchable in the lateral direction than in the longitudinal direction. The elastic member R62 can also be a non-woven fabric or other suitable material, and the present disclosure is not limited in this regard.

[0289] When the elastic member R62 is stretched in the lateral direction, the elastic member R62 as a whole will stretch in the lateral direction due to the deformation of the first extension portions R621 and the second extension portions R622 into a flat shape, and will contract due to the contraction force if the load is removed, and return to the original state without load.

[0290] According to the present disclosure, the elastic member R62 is elastically stretchable in the lateral direction, and can achieve self-adaptive adjustment of the width of the seating area when the infant faces inwards or outwards, without the need for additional adjustment actions.

[0291] When the infant faces outwards, i.e., faces away from the caregiver, the seating position of the infant's hips makes the center of gravity of the infant closer to the waistband 1 in the longitudinal direction. At this time, the infant's hips are more located at the position of the leg support member 51, and the center of gravity of the infant will act less on the elastic member R62, so that the elastically stretchable material of the elastic member R62 is less affected by the weight, and the elastic member R62 is in a non-fully expanded state or a semi-contracted state, forming a seat pocket with a relatively narrow width and a relatively shallow depth (here, the depth is the direction perpendicular to the paper surface of FIGS. 57 and 58).

[0292] When the infant faces inwards, i.e., faces towards the caregiver, the seating position of the infant's hips makes the center of gravity of the infant closer to the torso support portion 32 in the longitudinal direction. At this time, the infant's hips are more located at the position of the elastic member R62, and the center of gravity of the infant will act more on the elastic member R62, so that the elastically stretchable material of the elastic member R62 is expanded and sunken due to the action of the infant's gravity, forming a seat pocket with a relatively wide width and a relatively deep depth (here, the depth is the direction perpendicular to the paper surface of FIGS. 57 and 58).

[0293] In the present embodiment, the leg supports 51 present an outwardly flared shape in the direction from the child support 3 to the waist belt 1, whereby a variety of use modes can be satisfied for the baby to ride facing the caregiver and to ride facing away from the caregiver. Thus, the distance between the two leg supports 51 on the side closer to the waist belt 1 is greater than the distance on the side closer to the child support 3. In order to keep the shape of the elastic member 52 as an approximate regular shape (for example, the two side edges in the lateral width direction are substantially parallel, which is advantageous for the manufacture and cutting of the elastic member 52), a transition connecting member R63 is further provided between the elastic member R62 and the leg support 51. The thickness of the transition connecting member R63 is less than the thickness of the leg support 51, which is advantageous for the deformation to form the pocket structure at this location.

[0294] The technical features of the above various aspects and various embodiments of the present disclosure can be combined in any manner. In order to make the description concise, not all possible combinations of the technical features in the above embodiments are described, however, as long as the combinations of the technical features do not contradict, they should be considered within the scope of the present disclosure.

[0295] The above-described embodiments only express several implementation manners of the present disclosure, and the description is relatively specific and detailed, but it should not be understood as a limitation on the scope of the disclosed patent. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present disclosure, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be subject to the appended claims.
