Technical Field

[0003] The present disclosure relates to the technical field of infant products, and more particularly to an infant or child carrier capable of adjusting the leg support of an infant or child. The present disclosure also relates to an infant or child carrier having a seat height adjustment structure. Background Art

[0004] Infant carriers allow caregivers to carry their infants hands-free while maintaining close contact with the child. Infant carriers must be ergonomically designed to reduce the burden on the user while also supporting the infant's hips, legs, waist, neck, and head, avoiding bending and unnecessary pressure to ensure comfort and safety.

[0005] Different age groups, different age groups of the same infant, and different ways of holding a baby require different seating spaces, particularly different seating widths. Most infant carriers currently on the market provide a fixed seating space for infants, making it difficult to adaptively adjust the width of the seat in the lateral direction, or in other words, the seating width. This results in poor comfort for the infant's hips and legs. Some other infant carriers, while capable of adjusting the seat width, are often complex and require manual adjustment, making them inconvenient to use. Utility Model Content

[0211] (1) First Aspect of the Application

[0212] According to a first embodiment of the present disclosure, there is provided an infant carrier (i.e., a child carrier). Figures 1 to 2 As shown, the infant carrier includes a waist belt A1, a shoulder belt A2, and a child support part A3 connected to the waist belt A1 and the shoulder belt A2 respectively. The shoulder belt A2 is arranged roughly along the depth direction of the child support part A3. One side of the child support part A3 is connected to the waist belt A1, and the side of the child support part A3 away from the waist belt A1 is detachably or non-detachably connected to the shoulder belt A2. That is, the upper side of the child support part A3 is connected to the shoulder belt A2, and the lower side of the child support part A3 is connected to the waist belt A1. In this embodiment, the upper side of the child support part A3 is detachably connected to the shoulder belt A2 through a connector (such as a buckle). In other embodiments, the child support part A3 may be fixedly connected to the shoulder belt A2. This application does not limit the specific connection method between the child support part A3 and the shoulder belt A2. Reference Figures 1 to 2The child support A3 comprises a hip support portion A31 and a torso support portion A32, which are interconnected. In this embodiment, the child support A3 is integrally formed. The hip support portion A31 is connected to the waist belt A1 on the side away from the torso support portion A32, while the torso support portion A32 is connected to the shoulder belt A2 on the side away from the hip support portion A31.

[0213] It is worth noting that the depth direction of the child support part A3 described in the previous paragraph and the following text specifically refers to the direction from the side where the child support part A3 is connected to the waist belt A1 to the side where the child support part A3 is connected to the shoulder belt A2, that is, the direction from the lower side to the upper side or the upper side to the lower side of the child support part A3.

[0214] Furthermore, if Figure 1 、 Figure 2 and 5 As shown, the infant carrier also includes a connecting portion A4 connected to the waist belt A1 and the shoulder straps A2. A storage space for an infant is formed between the connecting portion A4 and the child support member A3. The connecting portion A4 includes a first connecting portion A41 and a second connecting portion A42. The first connecting portion A41 is a generally rectangular piece of fabric. There are two first connecting portions A41, which are spaced apart and connected to corresponding shoulder straps A2. One side of the second connecting portion A42 is connected to each of the two second connecting portions A42, and the other side of the second connecting portion A42 is connected to each of the two shoulder straps A2. In one embodiment, the connecting portion A4 may be a single piece of fabric, with one side of the connecting portion A4 connected to the waist belt A1 and the other side of the connecting portion A4 connected to the shoulder straps A2. In another embodiment, the infant carrier may not include the connecting portion A4, and instead, the shoulder straps A2 may extend directly to and connect to the waist belt A1.

[0215] Reference Figure 1 、 Figure 2 and Figure 5 The side of the torso support portion A32 away from the hip support portion A31, i.e., the side of the child support member A3 away from the waist belt A1, is detachably connected to the shoulder belt A2, thus facilitating the infant's entry and exit from the storage space. During use, the waist belt A1 is first secured to the caregiver's waist, and the shoulder belts A2 are suspended from the caregiver's shoulders. The connecting portion A4 then rests against the caregiver's torso. The infant can then be lifted and the side of the child support member A3 away from the waist belt A1 is connected to the shoulder belt A2, placing the infant within the storage space. In this embodiment of the infant carrier, the storage space formed by the connecting portion A4 and the child support member A3 provides excellent protection for the infant.

[0216] Furthermore, if Figure 1 and Figure 2As shown, the infant carrier also includes leg supports A51 (located on the left and right sides relative to the hip support A31). The leg supports A51 are connected to the hip support A31 and can be switched between an expanded state and a collapsed state. The hip support A31 and the leg supports A51 form a seat A6 for supporting an infant. When the leg supports A51 are in the expanded state, at least a portion of the leg supports A51 (in this embodiment, the middle portion of the leg supports A51) is generally away from the hip support A31 in the transverse direction of the child support A3, thereby increasing the width of the seat A6. When the leg supports A51 are in the collapsed state, at least a portion of the leg supports A51 (in this embodiment, the middle portion of the leg supports A51) is generally moved toward the hip support A31 in the transverse direction of the child support A3, thereby decreasing the width of the seat A6.

[0217] It should be noted that the transverse width direction of the child support member A3 described in the previous paragraph and the following paragraph 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 member A3.

[0218] In this embodiment, if Figure 1 and Figure 2 As shown, the leg support portion A51 is elastically connected to the hip support portion A31 and can be switched between an extended state and a retracted state. Specifically, an elastic member A7 is connected between the hip support portion A31 and the leg support portion A51. The elastic member A7 can be switched between an extended state and a non-extended state, allowing the leg support portion A51 to switch between an extended state and a retracted state, thereby adjusting the width of the seat portion A6 in the lateral direction, that is, adjusting the sitting width of the infant. The elastic member A7 has greater elasticity than the hip support portion A31 and the leg support portion A51. When the seat portion A6 is subjected to an external force, the elastic member A7, the hip support portion A31, and the leg support portion A51 are all stretched, and the elastic member A7 elastically deforms more than the hip support portion A31 and the leg support portion A51. It should be noted that the extended state of the elastic part A7 refers to the state in which the elastic part A7 is stretched under the action of an external force (for example, the weight of an infant); the non-extended state of the elastic part A7 includes the natural extension state of the elastic part A7 when there is no external force or the force direction is inward squeezing, or the folded state in which the elastic part A7 is at least partially folded.

[0219] The infant carrier of this embodiment automatically switches the leg support A51 between an expanded and collapsed position under the infant's own weight, eliminating the need to manually adjust the width of the seat A6. This provides an appropriate seating width for the infant, effectively meeting the seating width requirements of infants of varying body shapes and in varying seating orientations. This provides excellent support for the infant's hips and legs, while also enhancing seating comfort. The infant carrier of this embodiment has a simple structure and is easy to use. In this embodiment, the elastic member A7 better wraps around the infant's hips and legs, further enhancing the support provided by the seat A6 and improving seating comfort.

[0220] Furthermore, the elastic member A7 can be switched between an extended state and a non-extended state according to the body shape of the infant or the sitting direction of the infant. Figure 1 When an infant sits in the forward position, the required sitting width is small, the downward curvature of the seat A6 is small, and the pulling force F generated by the infant's weight on the two sides of the elastic member A7 connecting the leg support A51 and the hip elastic member A7 is small (or because the elastic member A7 is still in a folded state, the two sides of the elastic member A7 have not yet been subjected to the pulling force F), so that the elastic member A7 is generally in a non-extended state. Figure 2 When an infant sits with his back to the seat, the width of the seat required by the infant is larger, and the downward curvature of the seat A6 is larger. The gravity of the infant generates a large pulling force F on both sides of the connection between the elastic part A7 and the leg support part A51 and the buttocks elastic part A7, causing the elastic part A7 to be stretched to an extended state.

[0221] Similarly, when the infant is smaller, the sitting width required by the infant is smaller, and the pulling force F generated by the infant's weight on the two sides of the connection between the elastic part A7 and the leg support part A51 and the buttocks elastic part A7 is smaller (or because the elastic part A7 is still in a folded state, the two sides of the elastic part A7 have not yet been subjected to the pulling force F), so that the elastic part A7 is roughly in a non-extended state; when the infant is larger, the pulling force F generated by the infant's weight on the two sides of the connection between the elastic part A7 and the leg support part A51 and the buttocks elastic part A7 is larger, so that the elastic part A7 is stretched to an extended state.

[0222] Furthermore, if Figure 1 and Figure 2 As shown, the two outer edges of the hip support portion A31 in the transverse direction are curved edges that are recessed toward the center of the child support member A3. This facilitates the placement of the leg support portion A51 and also allows the width of the seat portion A6 to be reduced to a smaller size when the infant is facing away from the caregiver or when the infant is smaller, thereby preventing the infant's legs from being constricted.

[0223] like Figures 1 to 2 As shown, a leg support portion A51 is provided on both sides of the hip support portion A31 in the transverse direction. Specifically, the two leg support portions A51 are disposed on either side of the hip support portion's outer edge A311. The transverse distance between the outer edges A513 of the two leg support portions defines the width of the seat portion A6. The outer edge A513 of the leg support portion refers to the side of the leg support portion A51 that is farther from the hip support portion A31 in the transverse direction of the child support member A3. When the leg support portion A51 is in the extended position, the middle portions of the outer edges A513 of the two leg support portions are relatively farther from the hip support portion A31. When the leg support portion A51 is in the retracted position, the middle portions of the outer edges A513 of the two leg support portions are relatively closer to the hip support portion A31. Two or two groups of elastic members A7 are provided accordingly. Each leg support portion A51 is connected to the hip support portion A31 by an elastic member A7. For ease of description, the following description will be made by taking the leg supporting portion A51 and the elastic member A7 located on one side of the hip supporting portion A31 as an example.

[0224] Specifically, if Figure 4 、 Figure 6 and Figure 7 As shown, the leg support portion A51 can be a multi-layer structure. A padding layer or filler is provided within the leg support portion A51, ensuring that the leg support portion A51 provides better support for the infant while also making the ride more comfortable. The padding layer or filler includes at least one of a hard sheet and an elastic filler. Similarly, the hip support portion A31 can also be a multi-layer structure. A padding layer or filler is provided within the hip support portion A31, ensuring that the hip support portion A31 provides better support for the infant while also making the ride more comfortable.

[0225] The elastic member A7, connected between the leg support A51 and the hip support A31, can be a single-layer structure, thinner than the leg support A51 and hip support A31, to enhance infant comfort. The elastic member A7 comprises an elastic sheet made of flexible elastic fabric, enabling it to effectively transition between extended and unextended states. In other embodiments, the elastic member A7 comprises at least one elastic band made of flexible elastic fabric, or a combination of at least one elastic band and at least one elastic sheet.

[0226] like Figures 3 to 6As shown, one end of the leg support portion A51 serves as a first connection end A511 and is connected to the child support member A3, while the other end of the leg support portion A51 serves as a second connection end A512 and is connected to the child support member A3 or the waist belt A1. Specifically, the first connection end A511 can be connected to the outer edge of the hip support portion A31 on one side near the torso support portion A32, and the second connection end A512 can be connected to the side of the waist belt A1 near the hip support portion A31. That is, the first connection end A511 and the second connection end A512 are generally distributed along the depth direction, with the first connection end A511 located on the side of the second connection end A512 away from the waist belt A1. The portion of the leg support portion A51 between the first connection end A511 and the second connection end A512 is not directly connected to the hip support portion A31, allowing at least a portion of the leg support portion A51 (in this embodiment, the middle portion of the leg support portion A51) to be moved away from or closer to the seat portion A6 in the lateral width direction of the child support A3, thereby adjusting the width of the seat portion A6. In this embodiment, the first connection end A511 and the second connection end A512 of the leg support portion A51 are both fixedly or detachably connected to the child support A3 or the waist belt A1. Therefore, the first connection end A511 and the second connection end A512 of the leg support portion A51 are fixed relative to the child support A3. Therefore, the middle portion of the leg support portion A51 described in this paragraph and above specifically refers to the portion of the leg support portion A51 between the first connection end A511 and the second connection end A512. Of course, in other embodiments, the other end of the leg support portion A51 can also be connected to the hip support portion A31 near the waist belt A1. Alternatively, the other end of the leg support portion A51 is connected to both the hip support portion A31 and the waist belt A1. The present application does not impose any restrictions on the specific connection position of the leg support portion A51, as long as the portion of the leg support portion A51 between the first connection end A511 and the second connection end A512 can be relatively far away from or close to the seat portion A6 in the lateral width direction of the child support A3.

[0227] Reference Figures 3 to 6The leg support portion A51 has a linear first connection point A514 offset from the outer edge A513 of the leg support portion A51. An elastic member A7, such as an elastic sheet, is connected to the first connection point A514 on one side of the child support portion A3 in the transverse direction. Specifically, one side of the elastic member A7 in the transverse direction is connected to the back side of the leg support portion A51 (i.e., the side of the leg support portion A51 facing the infant). The elastic member A7 and the leg support portion A51 can be connected by, for example, sewing. The hip support portion A31 has a linear second connection point A312. The second connection point A312 is located at or near the outer edge of the hip support portion A31 opposite the first connection point A514. The second connection point A312 is spaced apart from the first connection point A514. The other side of the elastic member A7 (e.g., elastic sheet) in the transverse direction of the child support portion A3 is connected to the second connection point A312. Specifically, the other side of the elastic member A7 in the transverse direction of the child support member A3 can be connected to the back of the hip support portion A31 (i.e., the side of the hip support portion A31 facing the infant), or it can be connected to the interior of the hip support portion A31, i.e., between the multi-layer structure of the hip support portion A31. The elastic member A7 can be connected to the hip support portion A31 by, for example, sewing. In embodiments where the elastic member A7 includes, for example, multiple elastic bands, one end of each elastic band can be connected to the back of the leg support portion A51, and the other end can be connected to the interior of the hip support portion A31 or the back of the hip support portion A31.

[0228] Reference Figure 4 、 Figure 6 and Figure 7 The portion of the leg support portion A51 near the first connection end A511, the upper side of the elastic member A7, and the outer edge A311 of the hip support portion together enclose a first opening A81. This increases the elastic clearance of the leg support portion A51. Correspondingly, the portion of the leg support portion A51 near the second connection end A512, the lower side of the elastic member A7, and the outer edge A311 of the hip support portion together enclose a second opening A82. This increases the elastic clearance of the leg support portion A51. Of course, in other embodiments, the first opening A81 and the second opening A82 may not be provided, or only the first opening A81 or the second opening A82 may be provided.

[0229] In one embodiment, if Figures 1 to 4As shown, the seat portion A6 also includes a wing portion A52, which is connected to the leg support portion A51 on one side in the transverse direction of the child support part A3, and extends toward the hip support portion A31 on the other side in the transverse direction of the child support part A3. Specifically, the wing portion A52 is connected to the first connection position A514 of the leg support portion A51 and at least partially covers the elastic member A7, the first opening A81 or the second opening A82, so that the infant carrier is more beautiful when viewed from the front (i.e., the side facing away from the infant). In addition, by extending the wing portion A52 toward the hip support portion A31 in the transverse direction, the support area at the first opening A81 and the second opening A82 is increased, making the infant leg support more comfortable. In this embodiment, the wing portion A52 is integrally formed with the leg support portion A51. In another embodiment, the wing portion A52 can be connected to the leg support portion A51 by, for example, sewing. Continue to refer to Figures 1 to 4 The wing parts A52 are correspondingly set to two, and the two wing parts A52 are respectively connected to the corresponding first connection positions A514 in the two leg supporting parts A51.

[0230] In other embodiments not shown, the wing portion A52 can also be connected to the hip support portion A31 on one side of the child support member A3 in the transverse direction, at least partially covering the elastic member A7, the first opening A81, and the second opening A82, thereby enhancing the appearance of the infant carrier when viewed from the front. In this embodiment, the wing portion A52 is integrally formed with the hip support portion A31. In other embodiments, the wing portion A52 can be connected to the hip support portion A31 by, for example, sewing.

[0231] The operating principle of the infant carrier in this embodiment is as follows:

[0232] Reference Figure 2 When the sitting width required for the infant's buttocks and legs is large, for example, when the infant sits with his back to the baby (i.e. facing the caregiver), the downward curvature of the seat A6 is large, and the pulling force F generated by the infant's gravity on both sides of the connection between the elastic member A7 and the leg support member A51 and the buttocks elastic member A7 is large. The elastic member A7 is stretched to an extended state to better wrap the infant's legs and buttocks. At this time, the leg support member A51 is in an expanded state, and the middle parts of the two leg support members A51 are relatively far away from the buttocks support member A31. Correspondingly, the width of the seat A6 is increased, thereby ensuring that the baby's legs are in an M-shaped structure instead of hanging directly, which can provide good support for the infant's thighs. Figure 1When the sitting width required for the infant's buttocks and legs is small, for example, when the infant sits with his back to the baby (i.e., facing the caregiver), the downward curvature of the seat A6 is small, and the pulling force F generated by the infant's gravity on the two sides of the connection between the elastic member A7 and the leg support part A51 and the buttocks elastic member A7 is small (or because the elastic member A7 is still in a folded state, the two sides of the elastic member A7 have not yet been affected by the pulling force F). The elastic member A7 is in a non-extended state, so that the leg support part A51 is in a retracted state, and the middle part of the two leg support parts A51 is relatively close to the buttocks support part A31. Correspondingly, the width of the seat A6 is reduced, so that the infant's legs will not be squeezed, making the infant more comfortable to sit.

[0233] Of course, the width adjustment of the seat A6 is not limited to the situations where the infant sits facing backward or forward. For example, under the same riding mode, for infants of different sizes, larger infants require a correspondingly larger width of the seat A6 due to their larger hips and legs. Larger infants have a greater weight, so when they sit, the elastic part A7 can be extended and partially wrap the infant's legs and buttocks, so that the leg support part A51 is in an expanded state, thereby providing the infant with a larger seat A6 width, ensuring that the baby's legs are in an M-shaped structure instead of hanging directly, and providing good support for the infant's thighs. Similarly, smaller infants and young children require a smaller width of the seat portion A6 due to their smaller hip and leg sizes. Smaller infants and young children also have a smaller weight, so when they sit, the elastic member A7 can be in a non-extended state, so that the leg support portion A51 is in a retracted state. The middle part of the leg support portion A51 is relatively close to the hip support portion A31, so that the width of the seat portion A6 is reduced, which will not cause the legs to be squeezed, thereby making the infant and young child more comfortable to sit.

[0234] Figures 8 to 14 The second embodiment of the present application is shown as an infant carrier. This embodiment differs from the previous embodiment in at least the following ways:

[0235] In this embodiment, the seat A6 is not provided with the elastic member A7. The portion between the first connection end A511 and the second connection end A512 of the leg support portion A51 is spaced apart from the hip support portion A31 to form an adjustment port A83. The adjustment port A83 is in the open state (refer to Figure 9 、 Figure 13 and Figure 17 ) and closed state (refer to Figure 8 、 Figure 10 and Figure 12 ) so that the leg support part A51 can be switched between the expanded state and the folded state, so that the middle part of the leg support part A51 can be away from or close to the seat part A6, thereby adjusting the width of the seat part A6.

[0236] In this embodiment, referring to Figure 10 and Figure 12 When the baby carrier is naturally flat, adjust the opening A83 (refer to Figure 11 ) is blocked by the wing portion A52. Figure 8 When the infant sits forward, the width required for the infant's buttocks and legs is small, the leg support part A51 is in a folded state, and the middle part of the leg support part A51 is relatively close to the buttocks support part A31. At this time, the adjustment port A83 ( Figure 8 (not shown) is blocked by the leg support portion A51 or the wing portion A52. Figure 9 and Figure 17 When the infant sits with his back to the seat, the width required for the infant's buttocks and legs is larger, the leg support part A51 is in the unfolded state, and the middle part of the leg support part A51 is relatively far away from the buttocks support part A31. At this time, the adjustment port A83 may be exposed (refer to Figure 9 ) or may be blocked by the leg support portion A52 or the wing portion A52 (see Figure 14 ), and this application does not limit this. The arrangement of other components in this embodiment can refer to the above embodiment and will not be repeated here.

[0237] Figures 15 to 18 The third embodiment of the present application is shown as an infant carrier. This embodiment differs from the first embodiment in at least the following ways:

[0238] In this embodiment, if Figure 15 and Figure 16 As shown, the seat portion A6 does not include the elastic member A7. The leg support portion A51 has a generally trapezoidal structure, comprising a first side A515 and a second side A516 that are disposed opposite and substantially parallel to each other, and a third side A517 and a fourth side A518 that are disposed opposite and at an angle to each other. The first side A515 forms the outer edge A513 of the leg support portion. The second side A516 is shorter than the first side A515 and extends toward the middle of the width of the child support portion A3. The third side A517 and the fourth side A518 are respectively connected between the first side A515 and the second side A516, with the third side A517 being further away from the waist belt A1 than the fourth side A518.

[0239] like Figure 16As shown, the first side A515 of the leg support portion A51 has a first connection end A511 and a second connection end A512 at either end. Similar to the first embodiment, the first connection end A511 is connected to the child support member A3, and the second connection end A512 is connected to the child support member A3 or the waist belt A1. The first connection end A511 is located on the side of the second connection end A512 away from the waist belt A1, and the location where the child support member A3 connects to the first connection end A511 is a third connection location A313. The second side A516 of the leg support portion A51 is connected to a fourth connection location A314 of the child support member A3. Specifically, the fourth connection location A314 is linear and located on the back side of the child support member A3 (i.e., the side of the child support member A3 facing the infant). The fourth connection location A314 is located on the hip support portion A31 and offset from the outer edge A311 of the hip support portion. In this embodiment, the second side A516 of the leg support portion A51 is sewn to the fourth connection position A314 of the child support member A3. Figure 17 From the front side of the child support A3 (i.e., the side of the child support A3 facing away from the infant), the sewing lines of the second side A516 and the fourth connection position A314 will not be visible, which can make the child support A3 look more beautiful and neat when in use.

[0240] like Figure 16 As shown, the length of the leg support portion A51 from the first side A515 to the second side A516 is greater than the length of the child support A3 from the third connection position A313 to the fourth connection position A314, allowing the leg support portion A51 to switch between an extended state and a retracted state. When the leg support portion A51 is in the extended state, the first side A515 of the leg support portion A51, i.e., the outer edge A513 of the leg support portion, moves away from the hip support portion A31 in the lateral width direction of the child support A3, thereby increasing the width of the seat portion A6. When the leg support portion A51 is in the retracted state, the first side A515 of the leg support portion A51, i.e., the outer edge A511 of the leg support portion, moves toward the hip support portion A31 in the lateral width direction of the child support A3, thereby decreasing the width of the seat portion A6.

[0241] It should be understood that the length of the leg support portion A51 from the first side A515 to the second side A516 referred to herein specifically refers to the actual length of the fabric forming the leg support portion A51 between the first side A515 and the second side A516. Similarly, the length of the child support member A3 from the third connection location A313 to the fourth connection location A314 refers to the actual length of the fabric forming the child support member A3 between the third connection location A313 and the fourth connection location A314. In this embodiment, the leg support portion A51 includes a filling portion A5191 and a deforming portion A5192, which are adjacently arranged along the width of the child support member A3. Specifically, the leg support portion A51 has a separation position A5193 located between the first side A515 and the second side A516. The portion of the leg support portion A511 from the first side A515 to the separation position A5193 forms a filling portion A5191, and the portion of the leg support portion A511 from the separation position A5193 to the second side A516 forms a deformable portion A5192. Specifically, the filling portion A5191 is a multi-layer structure with a filling layer or filler inside to provide sufficient support for the infant's legs. The deformable portion A5192 is made of ordinary woven fabric. Separation position A5193 is a dividing stitching line, which separates the filling portion A5191 and the deformable portion A5192.

[0242] The deformable portion A5192 is switchable between a curled state and an extended state, thereby enabling the deformable portion A5192 to switch between an expanded state and a folded state. When the infant carrier is free of external force or subjected to inward squeezing, the deformable portion A5192 is in a naturally curled state, and the first side A515 of the leg support portion A51, i.e., the outer edge A513 of the leg support portion, moves toward the hip support portion A31 in the lateral width of the child support member A3, thereby reducing the width of the seat portion A6. When the infant carrier is subjected to external force, such as when an infant is riding in the infant carrier, the deformable portion A5192 is appropriately stretched and in an extended state, and the first side A515 of the leg support portion A51, i.e., the outer edge A511 of the leg support portion, moves away from the hip support portion A31 in the lateral width of the child support member A3, thereby increasing the width of the seat portion A6.

[0243] Furthermore, if Figure 16 As shown, the length of the first side A515 of the leg support portion A51 is L1, and the length of the second side A516 of the leg support portion A51 is L2. Then L1 and L2 satisfy the following relationship:

[0244] L2 / L1=1 / 3~1 / 2.

[0245] This arrangement ensures that the second side A516 of the leg support portion A51 has an appropriate length. Since the leg support portion A51 is used to connect to the linear fourth connection position A314 on the child support piece A3, the connection strength between the leg support portion A51 and the child support piece A3 and the support stability of the leg support portion A51 can be ensured.

[0246] Furthermore, if Figure 16 As shown, similar to the first embodiment, a leg support portion A51 is provided on both sides of the hip support portion A31 in the transverse direction. The distance between the second sides A516 of the two leg support portions A51 is W1, and the distance between the first sides A515 of the two leg support portions A51 is W2. Then, W1 and W2 satisfy the following relationship:

[0247] W1 / W2=1 / 3~2 / 3

[0248] This arrangement ensures that the size of the leg support portion A51 in the lateral width direction and the size of the entire seat portion A6 in the lateral width direction are maintained within a reasonable range, thereby ensuring the comfort and flexibility of the support of the seat portion A6 in the lateral width direction.

[0249] Furthermore, if Figure 17 and Figure 18 As shown, a first opening A81 is formed between the third side A517 and the child support A3, and a second opening A82 is formed between the fourth side A518 and the child support A3. The infant carrier also includes a wing portion A52. One side of the wing portion A52 is connected to the fifth connection location A615 of the hip support A31. The side of the wing portion A52, facing away from the hip support A31 in the width direction, forms a movable side A521. The movable side A521 is spaced apart from the leg support A51 to form a third opening A84. The third opening A84 communicates with both the first opening A81 and the second opening A82, allowing the first and second openings A81 and A82 to be exposed through the third opening A84. The wing portion A52 at least partially covers the first opening A81 or the second opening A82 to maintain the neat and aesthetic appearance of the child support A3, while also providing some support. In this embodiment, the fifth connection position A315 and the fourth connection position A314 are actually located at the same position on the back and front sides of the child support member A3. Figure 17 and Figure 18As shown, when the infant carrier is naturally flat, the first opening A81 and the second opening A82 are obscured by the wing portion A52. When the infant is seated in the upright position, the required seating width for the infant's hips and legs is smaller, and the leg support portion A51 is in a retracted state. Specifically, because the length from the first side A515 to the second side A516 is greater than the length from the third connection point A313 to the fourth connection point A314 of the child support A3, the leg support portion A51 is curled up, bringing the middle portion of the leg support portion A51 relatively close to the hip support portion A31. In this state, the first and second openings A82 are obscured by the wing portion A52. When an infant sits with his back to the seat, the sitting width angle required for the infant's buttocks and legs is larger, and the leg support part A51 is in an expanded state, that is, the leg support part A51 is stretched out due to being supported by the infant's buttocks and legs, so that the middle part of the leg support part A51 is relatively far away from the buttocks support part A31. At this time, the first opening A81 and the second opening A82 may be exposed through the third opening A84 or may be at least partially blocked by the wing part A52.

[0250] (2) Second Aspect of the Application

[0251] Example 1

[0252] The first embodiment of the present disclosure provides a child carrier B1000. Figures 19 to 20 As shown, the child carrier B1000 includes a waist belt B120, a shoulder strap B110, and a bearing assembly B200 connected to the waist belt B120 and the shoulder strap B110 respectively. The shoulder strap B110 is arranged roughly along the depth direction of the bearing assembly B200. One side of the bearing assembly B200 is connected to the waist belt B120, and the side of the bearing assembly B200 away from the waist belt B120 is detachably connected to the shoulder strap B110. That is, the upper side of the bearing assembly B200 is connected to the shoulder strap B110, and the lower side of the bearing assembly B200 is connected to the waist belt B120. In this embodiment, the upper side of the bearing assembly B200 is detachably connected to the shoulder strap B110 via a connector (such as a buckle). In other embodiments, the bearing assembly B200 may also be fixedly connected to the shoulder strap B110. This application does not limit the specific connection method between the bearing assembly B200 and the shoulder strap B110. Refer to Figures 19 to 20 The load-bearing assembly B200 includes a hip support portion B210 and a torso support portion B220 that are interconnected. In this embodiment, the load-bearing assembly B200 is integrally formed. The side of the hip support portion B210 away from the torso support portion B220 is connected to the waist belt B120, and the side of the torso support portion B220 away from the hip support portion B210 is connected to the shoulder strap B110.

[0253] It is worth noting that the depth direction of the supporting component B200 described in the previous paragraph and the following paragraph specifically refers to the direction from the side where the supporting component B200 is connected to the waist belt B120 to the side where the supporting component B200 is connected to the shoulder strap B110, that is, the direction from the lower side to the upper side or the upper side to the lower side of the supporting component B200.

[0254] Furthermore, if Figure 19 、 Figure 20 and 23 As shown, the child carrier B1000 also includes a connecting portion B4 connected to the waist belt B120 and the shoulder straps B110. A space for accommodating an infant is formed between the connecting portion B4 and the carrier assembly B200. The connecting portion B4 includes a first connecting portion B41 and a second connecting portion B42. The first connecting portion B41 is a generally rectangular piece of fabric. There are two first connecting portions B41, spaced apart and connected to corresponding shoulder straps B110. One side of the second connecting portion B42 is connected to each of the two second connecting portions B42, and the other side of the second connecting portion B42 is connected to each of the two shoulder straps B110. In one embodiment, the connecting portion B4 can also be a single piece of fabric, with one side of the connecting portion B4 connected to the waist belt B120 and the other side of the connecting portion B4 connected to the shoulder straps B110. In another embodiment, the child carrier B1000 does not include the connecting portion B4, but instead has the shoulder straps B110 extend to the waist belt B1 and connect to the waist belt B120.

[0255] Reference Figure 19 、 Figure 20 and Figure 23 The side of the trunk support portion B220 away from the hip support portion B210, that is, the side of the carrying assembly B200 away from the waist belt B120, is detachably connected to the shoulder belt B110, thereby facilitating the entry and exit of infants (also known as children) into and out of the storage space. During use, the waist belt B120 can be first secured to the caregiver's waist, and the shoulder belts B110 can be hung from the caregiver's shoulders. At this point, the connecting portion B4 rests against the caregiver's torso. The infant can then be picked up and the side of the carrying assembly B200 away from the waist belt B120 is connected to the shoulder belt B110, allowing the infant to sit in the storage space. In the child carrier B1000 of this embodiment, the storage space formed by the connecting portion B4 and the carrying assembly B200 provides better wrapping and protection for infants.

[0256] Furthermore, if Figure 19 and Figure 20As shown, the child carrier B1000 also includes leg supports B230 (disposed on the left and right sides relative to the hip support B210). The leg supports B230 are connected to the hip support B210 and can be switched between an expanded state and a folded state. Specifically, the leg supports B230 have a first connection end B231 and a second connection end B232. The first connection end B231 is connected to the carrying assembly B200, and the second connection end B232 is connected to the waist belt B120 or the carrying assembly B200. In the depth direction, at least a portion of the leg supports B230 located between the first connection end B231 and the second connection end B232 is not connected to the hip support B210. The hip support B210 and the leg supports B230 form a seat B6 for supporting an infant or young child. When the leg support portion B230 is in the expanded state, at least a portion of the leg support portion B230 (in this embodiment, the middle portion of the leg support portion B230) is generally away from the hip support portion B210 in the lateral width direction of the support assembly B200, thereby increasing the width of the seat portion B6. When the leg support portion B230 is in the collapsed state, at least a portion of the leg support portion B230 (in this embodiment, the middle portion of the leg support portion B230) is generally closer to the hip support portion B210 in the lateral width direction of the support assembly B200, thereby decreasing the width of the seat portion B6.

[0257] It is worth noting that the horizontal width direction of the carrier assembly B200 described in the previous paragraph and the following paragraph specifically refers to the direction from the left side to the right side or the right side to the left side of the carrier assembly B200.

[0258] In this embodiment, if Figure 19 and Figure 20 As shown, the leg support portion B230 is elastically connected to the hip support portion B210 and is switchable between an extended state and a retracted state. Specifically, an elastic member B7 is connected between the hip support portion B210 and the leg support portion B230. The elastic member B7 is switchable between an extended state and a non-extended state, allowing the leg support portion B230 to switch between an extended state and a retracted state, thereby adjusting the width of the seat portion B6 in the lateral direction, that is, adjusting the sitting width of the infant. The elastic member B7 has a greater elasticity than that of the hip support portion B210 and the leg support portion B230. When the seat portion B6 is subjected to an external force, the elastic member B7, the hip support portion B210, and the leg support portion B230 are all stretched, and the elastic member B7 deforms more than the hip support portion B210 and the leg support portion B230. It should be noted that the extended state of the elastic part B7 refers to the state in which the elastic part B7 is stretched under the action of external force (for example, the weight of an infant); the non-extended state of the elastic part B7 includes the natural extension state of the elastic part B7 when there is no external force or the force direction is inward squeezing, or the folded state in which the elastic part B7 is at least partially folded.

[0259] The child carrier B1000 of this embodiment automatically switches the leg support B230 between an expanded and collapsed state under the infant's own weight, eliminating the need to manually adjust the width of the seat B6. This provides an appropriate seating width for the infant, effectively meeting the seating width requirements of infants of varying sizes and in varying seating orientations. It provides excellent support for the infant's buttocks and legs, while also enhancing their comfort. The child carrier B1000 of this embodiment has a simple structure and is easy to use. In this embodiment, the elastic member B7 better wraps around the infant's buttocks and legs, further increasing the support provided by the seat B6 and improving their comfort.

[0260] Furthermore, the elastic member B7 can be switched between an extended state and a non-extended state according to the body shape of the infant or the sitting direction of the infant. Figure 19 When an infant sits in the forward position, the required sitting width is small, the downward curvature of the seat B6 is small, and the pulling force F generated by the infant's weight on the two sides of the elastic member B7 connecting the leg support part B230 and the hip elastic member B7 is small (or because the elastic member B7 is still in a folded state, the two sides of the elastic member B7 have not yet been subjected to the pulling force F), so that the elastic member B7 is generally in a non-extended state. Figure 20 When an infant sits with his back to the seat, the width of the seat required by the infant is larger, and the downward curvature of the seat B6 is larger. The gravity of the infant generates a large pulling force F on both sides of the connection between the elastic part B7 and the leg support part B230 and the buttocks elastic part B7, causing the elastic part B7 to be stretched to an extended state.

[0261] Similarly, when the infant is smaller, the sitting width required by the infant is smaller, and the pulling force F generated by the infant's weight on the two sides of the connection between the elastic part B7 and the leg support part B230 and the hip elastic part B7 is smaller (or because the elastic part B7 is still in a folded state, the two sides of the elastic part B7 have not yet been subjected to the pulling force F), so that the elastic part B7 is roughly in a non-extended state; when the infant is larger, the pulling force F generated by the infant's weight on the two sides of the connection between the elastic part B7 and the leg support part B230 and the hip elastic part B7 is larger, so that the elastic part B7 is stretched to an extended state.

[0262] Furthermore, if Figure 19 and Figure 20 As shown, the two outer edges B214 of the hip support portion B210 in the transverse direction are curved edges that are recessed toward the center of the support assembly B200. This facilitates the placement of the leg support portion B230 and also allows the width of the seat portion B6 to be reduced to a smaller size when the infant is sitting with their back to the caregiver or when the infant is smaller, thereby preventing constriction on the infant's legs.

[0263] like Figures 19 to 20 As shown, a leg support portion B230 is provided on both sides of the hip support portion B210 in the transverse direction. Specifically, the two leg support portions B230 are disposed on either side of the hip support portion's outer edge B214. The transverse distance between the outer edges B236 of the two leg support portions defines the width of the seat portion B6. The outer edge B236 of the leg support portion refers to the side of the leg support portion B230 that is farther from the hip support portion B210 in the transverse direction of the support assembly B200. When the leg support portions B230 are in the extended position, the middle portions of the outer edges B236 of the two leg support portions are relatively farther from the hip support portion B210. When the leg support portions B230 are in the collapsed position, the middle portions of the outer edges B236 of the two leg support portions are relatively closer to the hip support portion B210. Two or two sets of elastic members B7 are provided accordingly. Each leg support portion B230 is connected to the hip support portion B210 by an elastic member B7. For ease of description, the following description will be made by taking the leg support portion B230 and the elastic member B7 located on one side of the hip support portion B210 as an example.

[0264] Specifically, if Figure 22 、 Figure 24 and Figure 25 As shown, the leg support portion B230 can be a multi-layer structure. A padding layer or filler is provided within the leg support portion B230, providing better support for the infant while also making the ride more comfortable. The padding layer or filler includes at least one of a hard sheet and an elastic filler. Similarly, the hip support portion B210 can also be a multi-layer structure. A padding layer or filler is provided within the hip support portion B210, providing better support for the infant while also making the ride more comfortable.

[0265] The elastic member B7 connecting the leg support B230 and the hip support B210 can be a single-layer structure, thinner than the leg support B230 and hip support B210, to enhance infant comfort. The elastic member B7 comprises an elastic sheet made of flexible elastic fabric, enabling it to effectively transition between extended and unextended states. In other embodiments, the elastic member B7 comprises at least one elastic band made of flexible elastic fabric, or a combination of at least one elastic band and at least one elastic sheet.

[0266] like Figures 21 to 24As shown, one end of the leg support portion B230 serves as a first connection end B231 and is connected to the load-bearing assembly B200, and the other end of the leg support portion B230 serves as a second connection end B232 and is connected to the load-bearing assembly B200 or the waist belt B120. Specifically, the first connection end B231 can be connected to the outer edge of the hip support portion B210 on a side close to the torso support portion B220, and the second connection end B232 can be connected to the side of the waist belt B120 close to the hip support portion B210. That is, the first connection end B231 and the second connection end B232 are distributed roughly along the depth direction, with the first connection end B231 located on the side of the second connection end B232 away from the waist belt B120. The portion of the leg support portion B230 located between the first connection end B231 and the second connection end B232 is not directly connected to the hip support portion B210, allowing at least a portion of the leg support portion B230 (in this embodiment, the middle portion of the leg support portion B230) to move away from or closer to the seat portion B6 in the lateral width direction of the support assembly B200, thereby adjusting the width of the seat portion B6. In this embodiment, the first connection end B231 and the second connection end B232 of the leg support portion B230 are both fixedly or detachably connected to the support assembly B200 or the waist belt B120. Therefore, the first connection end B231 and the second connection end B232 of the leg support portion B230 are fixed relative to the support assembly B200. It is worth noting that the middle portion of the leg support portion B230 specifically refers to the portion of the leg support portion B230 located between the first connection end B231 and the second connection end B232. Of course, in other embodiments, the other end of the leg support portion B230 can also be connected to the hip support portion B210 near the waist belt B120. Alternatively, the other end of the leg support portion B230 can be connected to both the hip support portion B210 and the waist belt B120. This application does not limit the specific connection location of the leg support portion B230, as long as the portion of the leg support portion B230 located between the first connection end B231 and the second connection end B232 can be relatively far away from or close to the seat portion B6 in the lateral direction of the support assembly B200.

[0267] Reference Figures 21 to 24The leg support portion B230 has a linear first connection point B237 offset from the outer edge B236 of the leg support portion. An elastic member B7, such as an elastic sheet, is connected to the first connection point B237 on one side of the carrier assembly B200 in the transverse direction. Specifically, one side of the elastic member B7 in the transverse direction is connected to the back side of the leg support portion B230 (i.e., the side of the leg support portion B230 facing the infant). The elastic member B7 and the leg support portion B230 can be connected by, for example, sewing. The hip support portion B210 has a linear second connection point B215. The second connection point B215 is located at or near the outer edge of the hip support portion B210 opposite the first connection point B237. The second connection point B215 is spaced apart from the first connection point B237. The other side of the elastic member B7 (e.g., elastic sheet) in the transverse direction of the carrier assembly B200 is connected to the second connection point B215. Specifically, the other side of the elastic member B7 in the transverse direction of the supporting assembly B200 can be connected to the back of the hip support portion B210 (i.e., the side of the hip support portion B210 facing the infant), or can be connected to the interior of the hip support portion B210, i.e., connected between the multi-layer structure of the hip support portion B210. The elastic member B7 and the hip support portion B210 can be connected by, for example, sewing. In an embodiment where the elastic member B7 includes, for example, multiple elastic bands, one end of each elastic band can be connected to the back of the leg support portion B230, and the other end can be connected to the interior of the hip support portion B210 or the back of the hip support portion B210.

[0268] Reference Figure 22 、 Figure 24 and Figure 25 The portion of the leg support portion B230 near the first connection end B231, the upper side of the elastic member B7, and the outer edge B214 of the hip support portion together form a first opening B233. This increases the elastic clearance of the leg support portion B230. Correspondingly, the portion of the leg support portion B230 near the second connection end B232, the lower side of the elastic member B7, and the outer edge B214 of the hip support portion together form a second opening B234. This increases the elastic clearance of the leg support portion B230. Of course, in other embodiments, the first opening B233 and the second opening B234 may not be provided, or only the first opening B233 or the second opening B234 may be provided.

[0269] In one embodiment, if Figures 19 to 22As shown, the seat portion B6 also includes a wing portion B52. The wing portion B52 is connected to the leg support portion B230 on one side in the transverse direction of the support assembly B200, and extends toward the hip support portion B210 on the other side in the transverse direction of the support assembly B200. Specifically, the wing portion B52 is connected to the first connection position B237 of the leg support portion B230 and at least partially covers the elastic member B7, the first opening B233, and the second opening B234. This makes the child carrier B1000 more aesthetically pleasing when viewed from the front (i.e., the side facing away from the infant). In addition, by extending the wing portion B52 toward the hip support portion B210 in the transverse direction, the support area at the first opening B233 and the second opening B234 is increased, making the infant's leg support more comfortable. In this embodiment, the wing portion B52 is integrally formed with the leg support portion B230. In another embodiment, the wing portion B52 can be connected to the leg support portion B230 by, for example, sewing. Figures 19 to 22 The wing parts B52 are correspondingly set to two, and the two wing parts B52 are respectively connected to the corresponding first connection positions B237 in the two leg support parts B230.

[0270] In other embodiments not shown, the wing portion B52 may also be connected to the hip support portion B210 on one side of the carrier assembly B200 in the transverse direction, at least partially covering the elastic member B7, the first opening B233, and the second opening B234, thereby enhancing the appearance of the child carrier B1000 when viewed from the front. In this embodiment, the wing portion B52 is integrally formed with the hip support portion B210. In other embodiments, the wing portion B52 may be connected to the hip support portion B210 by, for example, sewing.

[0271] The operating principle of the child carrier B1000 in this embodiment is as follows:

[0272] Reference Figure 20 When the sitting width required for the infant's buttocks and legs is large, for example, when the infant sits with his back to the baby (i.e. facing the caregiver), the downward curvature of the seat B6 is large, and the pulling force F generated by the infant's gravity on both sides of the connection between the elastic member B7 and the leg support member B230 and the buttocks elastic member B7 is large. The elastic member B7 is stretched to an extended state to better wrap the infant's legs and buttocks. At this time, the leg support member B230 is in an expanded state, and the middle parts of the two leg support members B230 are relatively far away from the buttocks support member B210. Correspondingly, the width of the seat B6 increases, thereby ensuring that the baby's legs are in an M-shaped structure instead of hanging directly, which can provide good support for the infant's thighs. Figure 19When the sitting width required for the infant's buttocks and legs is small, for example, when the infant sits with his back to the baby (i.e., facing the caregiver), the downward curvature of the seat B6 is small, and the pulling force F generated by the infant's gravity on the two sides of the connection between the elastic member B7 and the leg support part B230 and the buttocks elastic member B7 is small (or because the elastic member B7 is still in a folded state, the two sides of the elastic member B7 have not yet been subjected to the pulling force F). The elastic member B7 is in a non-extended state, so that the leg support part B230 is in a retracted state, and the middle part of the two leg support parts B230 is relatively close to the buttocks support part B210, so that the seat B6 has a smaller width, which will not cause the legs to be squeezed, making the infant more comfortable to sit.

[0273] Of course, the width adjustment of the seat B6 is not limited to the situations where the infant sits facing backward or forward. For example, under the same riding mode, for infants of different sizes, larger infants have larger hips and legs, so the required width of the seat B6 is also correspondingly larger. Larger infants have a larger weight, so when they sit, the elastic part B7 can be extended and partially wrap the infant's legs and buttocks, so that the leg support part B230 is in an expanded state, thereby providing the infant with a larger seat B6 width, ensuring that the baby's legs are in an M-shaped structure instead of hanging directly, and can provide good support for the infant's thighs. Similarly, smaller infants and toddlers require a smaller width of the seat B6 due to their smaller hip and leg sizes. Smaller infants and toddlers also have a smaller weight, so when they sit, the elastic part B7 can be in a non-extended state, so that the leg support part B230 is in a retracted state. The middle part of the leg support part B230 is relatively close to the hip support part B210, so that the seat B6 has a smaller width, which will not cause the legs to be squeezed, making the infant and toddler more comfortable to sit.

[0274] Example 2

[0275] Figures 26 to 32 A child carrier B1000 according to a second embodiment of the present disclosure is shown. This embodiment differs from the first embodiment in at least the following ways:

[0276] In this embodiment, the seat B6 is not provided with the elastic member B7. The portion between the first connection end B231 and the second connection end B232 of the leg support B230 is spaced apart from the hip support B210 to form an adjustment port B235. The adjustment port B235 is in the open state (refer to Figure 27 、 Figure 31 and Figure 32 ) and closed state (refer to Figure 26 、 Figure 28 and Figure 30) so that the leg support part B230 can be switched between the expanded state and the folded state, so that the middle part of the leg support part B230 can be away from or close to the seat part B6, thereby adjusting the width of the seat part B6.

[0277] In this embodiment, referring to Figure 28 and Figure 30 When the child carrier B1000 is naturally flat, the adjustment port B235 (refer to Figure 29 ) is blocked by the wing portion B52. Figure 26 When the infant sits forward, the sitting width required for the infant's buttocks and legs is small, the leg support part B230 is in a folded state, and the middle part of the leg support part B230 is relatively close to the buttocks support part B210. At this time, the adjustment port B235 ( Figure 26 Not shown) is blocked by the leg support portion B230 or the wing portion B52. Figure 27 and Figure 35 When the infant sits with his back to the seat, the width required for the infant's buttocks and legs is larger, the leg support part B230 is in the unfolded state, and the middle part of the leg support part B230 is relatively far away from the buttocks support part B210. At this time, the adjustment port B235 may be exposed (refer to Figure 27 ) or may be blocked by the leg support portion B230 or the wing portion B52 (refer to Figure 32 ), and this application does not limit this. The arrangement of other components in this embodiment can refer to the above embodiment and will not be repeated here.

[0278] Example 3

[0279] The third embodiment of the present disclosure provides a child carrier B1000, such as Figure 33As shown, the child carrier B1000 includes a waist belt B120, shoulder straps B110, a carrier assembly B200 connected to the waist belt B120 and shoulder straps B110, and a leg support B230 connected to the carrier assembly B200. The shoulder straps B110 are arranged generally along the depth direction of the carrier assembly B200. One side of the carrier assembly B200 is connected to the waist belt B120, and the side of the carrier assembly B200 away from the waist belt B120 is detachably connected to the shoulder straps B110. In other words, the upper side of the carrier assembly B200 is connected to the shoulder straps B110, and the lower side of the carrier assembly B200 is connected to the waist belt B120. The portion of the carrier assembly B200 near the waist belt B120 forms the hip support B210, and the upper side of the carrier assembly B200 forms the torso support B220. The leg support portion B230 is connected to the hip support portion B210 and together with the leg support portion B230 forms a seat portion B6 for supporting an infant or young child. The leg support portion B230 is switchable between an expanded state and a collapsed state. Specifically, when the leg support portion B230 is in the expanded state, the leg support portion B230 is away from the hip support portion B210 in the lateral width direction of the support assembly B200, so that the seat portion B6 has a larger width. When the leg support portion B230 is in the collapsed state, the leg support portion B230 is closer to the hip support portion B210 in the lateral width direction of the support assembly B200, so that the seat portion B6 has a smaller width. It should be understood that the larger width and smaller width in this article can be referred to as the first width and the second width, respectively, and the second width is smaller than the first width.

[0280] There are at least the following differences between this embodiment and the child carrier B1000 in the aforementioned embodiment.

[0281] like Figure 33 and Figure 34 As shown, the first connection end B231 of the leg support part B230 is connected to the load-bearing component B200, and the second connection end B232 of the leg support part B230 is connected to the load-bearing component B200 or the waist belt B120. In the depth direction, at least a portion of the leg support part B230 located between the first connection end B231 and the second connection end B232 is not connected to the hip support part B210. In this embodiment, the number of leg support parts B230 is two, but not limited to this. The two leg support parts B230 are respectively located on the left and right sides of the hip support part B210. Figure 33 and Figure 34 The leg supporting portion B230 includes a first leg supporting portion B230e located on the left side of the hip supporting portion B210 and a second leg supporting portion B230f located on the right side of the hip supporting portion B210. Figure 34In this embodiment, the portion of the leg support portion B230 located between the first connection end B231 and the second connection end B232 is not directly connected to the hip support portion B210, so that at least a portion of the leg support portion B230 (the middle portion of the leg support portion B230 in this embodiment) is spaced apart from the hip support portion B210 and forms an adjustment opening B235. Specifically, in this embodiment, the leg support portion B230 is connected to the hip support portion B210 by an elastic member B7 between the approximately middle portion in the depth direction, and the hip support portion B210, and the elastic member B7 at least partially covers the adjustment opening B235. The elastic member B7 is switchable between an extended state and a non-extended state, so that the leg support portion B230 can be expanded or retracted relative to the hip support portion B210 (that is, equivalent to making the edge line 236 of the leg support portion B230 move away from or close to the hip support portion B210). More specifically, referring to Figure 33 The elastic member B7 partially covers the adjustment opening B235. The portion of the adjustment opening B235 not covered by the elastic member B7 forms a first opening B233 located above the elastic member B7 and a second opening B234 located below the elastic member B7. The elastic member B7, the leg support portion B230, and the hip support portion B210 collectively form the seat portion B6. In this embodiment, the number of elastic members B7 corresponds to the number of leg support portions B230. That is, approximately the longitudinal center of each leg support portion B230 is connected to the hip support portion B210 via an elastic member B7. In other embodiments, each leg support B230 may be provided with two or more elastic members B7 in the longitudinal depth portion between the first connection end B231 and the second connection end B232 of each leg support B230. The two or more elastic members B7 are spaced apart in the longitudinal depth direction. The leg support B230 is connected to the hip support portion via these elastic members B7, so that at least a portion of the leg support B230 between the first connection end B231 and the second connection end B232 is disconnected from the hip support portion B210. In an alternative embodiment, the elastic member B7 may not be provided between the leg support B230 and the hip support portion B210, and the leg support B230 may be switched between an open state and a closed state via an adjustment port B235, so that the leg support B230 can be expanded or retracted relative to the hip support portion B210.

[0282] like Figure 33As shown, the child carrier B1000 is further provided with an adjustment mechanism B800, which is configured to expand or contract the hip support portion B210. When the leg support portion B230 is in the expanded state, the leg support portion B230 is positioned away from the hip support portion B210 in the transverse width direction of the support assembly B200. This is equivalent to the outer edge B236 of the leg support portion B230 being positioned away from the hip support portion B210 in the transverse width direction. This increases the width of the seat portion B6, thereby increasing the seat portion B6's width. When the leg support portion B230 is in the contracted state, the leg support portion B230 is positioned closer to the hip support portion B210 in the transverse width direction of the support assembly B200. This is equivalent to the outer edge B236 of the leg support portion B230 being positioned closer to the hip support portion B210 in the transverse width direction. This reduces the seat portion B6's width. Among them, the adjustment mechanism B800 has an open state and a locked state. When the adjustment mechanism B800 is in the open state, the leg support part B230 can be expanded relative to the hip support part B210, so that the seat part B6 has a larger width; when the adjustment mechanism B800 is in the locked state, the leg support part B230 is retracted relative to the hip support part B210, so that the seat part B6 has a smaller width.

[0283] like Figures 34 to 35As shown, the adjustment mechanism B800 includes a first adjustment member B810 and a second adjustment member B820. The first adjustment member B810 is connected to the first leg support portion B230e, and the second adjustment member B820 is connected to the second leg support portion B230b. The first adjustment member B810 includes a first adjustment strap B811 and a first mating portion B812 disposed on the first adjustment strap B811. The first adjustment strap B811 is connected between the first leg support portion B230e and the first mating portion B812. This means that the first mating portion B812 is connected to the first leg support portion B230e via the first adjustment strap B811. The second adjustment member B820 includes a second adjustment strap B821 and a second mating portion B822 disposed on the second adjustment strap B821. The second adjustment strap B821 is connected to the second leg support portion B230f. This means that the second mating portion B822 is connected to the second leg support portion B230f via the second adjustment strap B821. The second mating portion B822 is adapted to cooperate with the first mating portion B812 to detachably connect the first adjustment strap B811 and the second adjustment strap B821, thereby switching the adjustment mechanism B800 between an open state and a locked state. When the first mating portion B812 and the second mating portion B822 cooperate with each other (i.e., the adjustment mechanism B800 is in a locked state), the two leg support portions B230 move closer together, thereby reducing the width of the seat B6 (i.e., making the seat B6 have a relatively small width). When the first mating portion B812 and the second mating portion B822 separate from each other (i.e., the adjustment mechanism B800 is in an open state), the two leg support portions B230 move away from each other, thereby increasing the width of the seat B6 (i.e., making the seat B6 have a relatively large width).

[0284] It should be noted that in this embodiment, when the adjustment mechanism B800 is in the open state, the relative position adjustment between the leg support part B230 and the hip support part B210 (i.e., the width adjustment of the seat part B6) is the same as the aforementioned first embodiment or second embodiment, and will not be repeated here.

[0285] like Figure 34 and Figure 35As shown, one end of the first adjustment belt B811 is connected to the first leg support portion B230e and forms a first fixed end B8111. The first matching portion B812 is provided on the first adjustment belt B811. One end of the second adjustment belt B821 is connected to the second leg support portion B230f and forms a second fixed end B8211, and the second matching portion B822 is provided on the second adjustment belt B821. Furthermore, the first matching portion B812 is movably provided on the first adjustment belt B811 to allow adjustment of the length of the first adjustment belt B811 between the first fixed end B8111 and the first matching portion B812 (i.e., the first adjustment length), thereby adjusting the width of the seat portion B6 when the adjustment mechanism B800 is in the locked state. The second fitting portion B822 can be movably arranged on the second adjustment band B821 to allow adjustment of the length of the second adjustment band B821 between the second fixed end B8211 and the second fitting portion B822 (i.e., the second adjustment length), thereby adjusting the width of the seat B6 when the adjustment mechanism B800 is in the locked state.

[0286] Of course, in some alternative embodiments, it may be that: the first fitting part B812 is fixedly set on the first adjustment band B811, the second fitting part B822 is fixedly set on the second adjustment band B821, and the first adjustment length and the second adjustment length are both fixed; or: the first fitting part B812 is movably set on the first adjustment band B811, the second fitting part B822 is fixedly set on the second adjustment band B821, the first adjustment length can be adjusted and changed, and the second adjustment length is fixed; or: the second fitting part B822 is movably set on the second adjustment band B821, the first fitting part B812 is fixedly set on the first adjustment band B811, the second adjustment length can be adjusted and changed, and the first adjustment length is fixed.

[0287] Reference Figure 34 In this embodiment, the first mating portion is a male buckle, and the second mating portion is a female buckle adapted to engage with the male buckle. In alternative embodiments, the first mating portion is, for example, a hook, and the second mating portion is, for example, a loop. Alternatively, the first mating portion and the second mating portion are a pair of snaps that can be interlocked. Alternatively, the first mating portion and the second mating portion are mating hook-and-loop fasteners.

[0288] Back to Figure 34 and Figure 35As shown, the first adjustment strap B811 and the second adjustment strap B821 are respectively connected to the middle portion of the corresponding leg support portion B230. Specifically, the first fixed end B8111 and the second fixed end B8211 are respectively connected to the middle portion of the corresponding leg support portion B230 in the depth direction. The leg support portion B230 includes a first side B238 close to the hip support portion B210 and a second side B239 away from the hip support portion B210. The first fixed end B8111 is connected to the second side B239 of the first leg support portion B230e, or to its first side B238, or to between its second side B239 and its first side B238; the second fixed end B8211 is connected to the second side B239 of the second leg support portion B230f, or to its first side B238, or to between its second side B239 and its first side B238. In this embodiment, the second side B239 of the leg support portion B230 forms the outer edge B236 of the leg support portion B230. The first fixed end B8111 and the second fixed end B8211 are respectively connected to the first side B238 of the corresponding leg support portion B230. The first adjustment strap B811 is connected to the front side of the leg support portion B230 (i.e., the side of the leg support portion B230 facing away from the infant during use) or to the inside of the leg support portion B230 (i.e., when the leg support portion B230 is a multi-layer structure, it is connected between the multi-layer structures). The first adjustment strap B811 is at least partially located on the front side of the hip support portion B210 (i.e., the side of the hip support portion B210 facing away from the infant during use). The second adjustment strap B821 is connected to the front side of the leg support portion B230 or to the inside of the leg support portion B230 via the second fixed end B8211. The second adjustment strap B821 is at least partially located on the front of the hip support portion B210, which facilitates operation of the first and second adjustment members B810 and B820 and prevents them from interfering with the infant in the child carrier B1000.

[0289] like Figure 34As shown, the bearing assembly B200 is further provided with a first limiting ring B911 and a second limiting ring B912. The first adjustment band B811 is inserted into the first limiting ring B911 to limit and guide the first adjustment band B811. The second adjustment band B821 is inserted into the second limiting ring B912 to limit and guide the second adjustment band B821 and to restrict the extension direction of the second adjustment band B821. Furthermore, the first mating portion B812 has a greater dimension in the depth direction than the first limiting ring B911 in the same direction, thereby limiting the movement of the first mating portion B812 toward the first fixed end B8111 by the first limiting ring B911. Similarly, the second mating portion B822 has a greater dimension in the depth direction than the second limiting ring B921 in the same direction, thereby limiting the movement of the second mating portion B822 toward the second fixed end B8211 by the second limiting ring B912. Among them, the first limiting ring B911 and the second limiting ring B912 have the same structure, and the number of the first limiting ring B911 can be one or more; the number of the second limiting ring B912 can be one or more, and this application does not impose any restrictions on this. The first limiting ring B911 and the second limiting ring B912 are, for example, cloth rings sewn on the front of the hip support part B210, but are not limited to this. The first limiting ring B911 and the second limiting ring B912 are spaced apart in the transverse width direction. The first fixed end B8111, the first limiting ring B911, the second limiting ring B912 and the second fixed end B8211 are roughly located on the same straight line (or the same arc) along the transverse width direction.

[0290] like Figure 33As shown, optionally, a shielding member B920 is further provided on the carrying assembly B200. The shielding member B920 is connected to the front of the carrying assembly B200 to cover the first adjustment member B810 and the second adjustment member B820, thereby making the front of the child carrier B1000 neater and more beautiful. At least a portion of the shielding member B920 is not connected to the carrying assembly B200, so that an operating port B921 is formed between the shielding member B920 and the carrying assembly B200, thereby allowing the first adjustment member B810 and the second adjustment member B820 to be operated through the operating port B921. Specifically, the shielding member B920 is, for example, a shielding cloth piece. The shielding member B920 has an upper end 922 and a lower end 923 that are opposite in the depth direction. The upper end 922 and the lower end 923 of the shielding member B920 are respectively fixed to the carrying assembly B200 by, for example, sewing. At least a portion of both sides of the shielding member B920 in the transverse direction is not connected to the carrying assembly B200, thereby forming two operating ports B921 that are interconnected in the transverse direction between the shielding member B920 and the carrying assembly B200. More specifically, the first adjustment member B810 and the second adjustment member B820 extend between the shielding member B920 and the carrying assembly B200 through corresponding operating ports B921, and the sizes of the two operating channels are suitable for the user to insert their hands to operate the first adjustment member B810 and the second adjustment member B820. In this embodiment, the shielding member B920 and the carrying assembly B200 form a pocket 925 to accommodate the first adjustment member B810 and the second adjustment member B820. The operating port B921 forms the opening of the pocket 925, through which the first adjustment member B810 and the second adjustment member B820 accommodated in the pocket 925 can be operated. In an alternative embodiment, the shielding member B920 is a multi-layer woven fabric structure, a pocket 925 is formed inside the shielding member B920 (ie, between the multi-layer woven fabric), and an opening of the pocket 925 is provided between the multi-layer woven fabric.

[0291] The operating principle of the child carrier B1000 in this embodiment is as follows.

[0292] When the width of the seat B6 required by an infant is smaller (for example, when the infant is sitting in the child carrier B1000 facing forward, or when the infant is smaller in size), the adjustment mechanism B800 is kept in the locked state (i.e., the first mating portion B812 and the second mating portion B822 are mated with each other), and the outer edges B236 of the two leg supports B230 are moved closer to the hip support portion B210, so that the outer edges B236 of the two leg supports B230 are moved closer to each other, thereby reducing the width of the seat B6 (i.e., making the seat B6 have a relatively small width). In this embodiment, the provision of the adjustment mechanism B800 can limit the width of the seat B6 to a relatively small range, thereby better adapting to the infant's width requirement for the seat B6 and avoiding repeated adjustment of the leg supports B230, thus making the child carrier B1000 more convenient to use. At the same time, when the adjustment mechanism B800 is in the locked state, it also provides a certain support for the seat B6 area, thereby reducing the probability of deformation and failure of the seat B6 and the elastic member B7.

[0293] When the seat portion B6 required by the infant is wider (for example, the infant is sitting with his back to the child carrier B1000, or the infant is larger in size), the following different adjustment methods can be used.

[0294] Method 1: Switch the adjustment mechanism B800 to the open state (that is, separate the first matching part B821 and the second matching part B822), and the width of the seat B6 can be adjusted by the method in the aforementioned embodiment 1 or embodiment 2, which will not be repeated here.

[0295] Method 2: Keep the adjustment mechanism B800 in a locked state (that is, the first fitting part B812 is engaged with the second fitting part B822), and change the first adjustment length (and / or the second adjustment length) by adjusting the position of the first fitting part B812 on the first adjustment band B811 (and / or the position of the second fitting part B822 on the second adjustment band B821), so that the seat B6 has a larger width.

[0296] Example 4

[0297] The fourth embodiment of the present disclosure provides a child carrier B1000, such as Figure 36As shown, the child carrier B1000 includes a waist belt B120, shoulder straps B110, a carrier assembly B200 connected to the waist belt B120 and shoulder straps B110, and a leg support B230 connected to the carrier assembly B200. The shoulder straps B110 are arranged generally along the depth direction of the carrier assembly B200. One side of the carrier assembly B200 is connected to the waist belt B120, and the side of the carrier assembly B200 away from the waist belt B120 is detachably connected to the shoulder straps B110. In other words, the upper side of the carrier assembly B200 is connected to the shoulder straps B110, and the lower side of the carrier assembly B200 is connected to the waist belt B120. The portion of the carrier assembly B200 near the waist belt B120 forms the hip support B210, and the upper side of the carrier assembly B200 forms the torso support B220. The leg support B230 is connected to the hip support B210 and together with the leg support B230 forms a seat B6 for supporting an infant or young child. The leg support B230 is switchable between an extended state and a retracted state. When the leg support B230 is in the extended state, it moves away from the hip support B210 in the lateral width of the support assembly B200, allowing the seat B6 to have a larger width. When the leg support B230 is in the retracted state, it moves closer to the hip support B210 in the lateral width of the support assembly B200, allowing the seat B6 to have a smaller width.

[0298] This embodiment differs from the child carrier B1000 in the aforementioned third embodiment in at least the following ways.

[0299] Reference Figure 37The second connection end B232 of the leg support B230 is connected to the load-bearing assembly B200 or the waist belt B120. At least a portion of the first connection end B231 is formed as a movable end B231a. This movable end B231a is not connected to the load-bearing assembly B200, that is, the movable end B231a is not connected, so that the first connection end B231 can move relative to the leg support B230. In the depth direction, the portion of the leg support B230 located between the first connection end B231 and the second connection end B232 is not directly connected to the hip support B210, so that at least a portion of the leg support B230 (in this embodiment, the middle portion of the leg support B230) is spaced apart from the hip support B210 and forms an adjustment port B235. Specifically, the leg support B230 and the hip support B210 are connected by an elastic member B7, which at least partially covers the adjustment port B235. The elastic member B7 can be switched between an extended and non-extended state, allowing the leg support portion B230 to expand or contract relative to the hip support portion B210. That is, in this embodiment, the middle portion of the leg support portion B230 is connected to the hip support portion B210 via the elastic member B7. In an alternative embodiment, the elastic member B7 may not be provided between the leg support portion B230 and the hip support portion B210, and a portion of the middle portion of the leg support portion B230 may be directly connected to the hip support portion B210.

[0300] like Figure 36 and Figure 37 As shown, the child carrier B1000 is also provided with an adjustment mechanism B800, and the first connection end B231 of one of the two leg supports B230 is adapted to be connected to the first connection end B231 of the other of the two leg supports B230 via the adjustment mechanism B800. The adjustment mechanism B800 has an open state and a closed state. When the adjustment mechanism B800 is in the open state, the width of the seat B6 is relatively large. When the adjustment mechanism B800 is in the closed state, the first connection ends B231 of the two leg supports B230 are connected to each other via the adjustment mechanism B800, and the width of the seat B6 is relatively small, which is smaller than the width of the seat B6 when the adjustment mechanism B800 is in the open state.

[0301] The adjustment mechanism B800 includes a first adjustment member B810 and a second adjustment member B820. The first adjustment member B810 includes a first adjustment strap B811 and a first mating portion B812 provided on the first adjustment strap B811. One end of the first adjustment strap B811 is connected to the movable end portion B231a of the first leg support portion B230e, and the other end extends toward the second leg support portion B230f. The second adjustment member B820 includes a second adjustment strap B821 and a second mating portion B822 provided on the second adjustment strap B821. One end of the second adjustment strap B821 is connected to the movable end portion B231a of the second leg support portion B230f, and the other end extends toward the leg support portion B230 to which the first adjustment strap B811 is connected. The first adjustment strap B811 and the first leg support portion B230e form an integral component, while the second adjustment strap B821 and the second leg support portion B230f form an integral component. The first mating portion B811 is adapted to mate with the second mating portion B821 to connect the first adjustment strap B811 to the second adjustment strap B821. It is noteworthy that in this embodiment, the mobility of the two movable ends B231a of the leg support portion can be appropriately limited, so that when the two adjustment members B810 and B820 are not connected, the movable ends B231a of the leg support portion can provide appropriate support, and the width of the seat portion B6 can be relatively large. For example, a limiting structure can be provided at a position corresponding to the movable end B231a of the hip support portion B210 or the shielding piece B920, and the limiting structure can be used to limit the mobility of the movable end B231a. Alternatively, a relatively large friction force can exist between the movable end B231a and the hip support portion B210 and / or the shielding piece B920 under normal conditions, and this relatively large friction force can be used to limit the mobility of the movable end B231a. In other embodiments, the movable end B231a of the leg support portion is highly mobile, so that when the two adjustment members B810 and B820 are not connected, the movable end B231a of the leg support portion cannot provide support, and the width of the seat portion B6 is relatively small.

[0302] Optionally, the number of at least one of the second fitting part B822 and the first fitting part B812 is at least two, so that the first adjustment band B811 and the second adjustment band B821 can be connected to each other at different positions through the mutual cooperation between the second fitting part B822 and the first fitting part B812, that is, the adjustment mechanism B800 has different width adjustment gears of the seat B6.

[0303] Reference Figures 36 to 37For example, there is one first mating portion B812, and at least two second mating portions B822. The at least two second mating portions B822 include a second mating portion B822a and a second mating portion B822b, with the second mating portion B822a being closer to the first adjustment band B811 in the transverse direction than the second mating portion B822b. When the first mating portion B812 and the second mating portion B822a engage, the adjustment mechanism B800 is in the first locked state, the leg support portion B230 is in the first retracted state, and the seat portion B6 has a relatively large retracted width that is smaller than the width when the adjustment mechanism B800 is in the open state. When the first mating portion B812 and the second mating portion B822b engage, the adjustment mechanism B800 is in the second locked state, the leg support portion B230 is in the second retracted state, and the seat portion B6 has a relatively small retracted width that is smaller than the aforementioned relatively large retracted width.

[0304] In some alternative embodiments, there are at least two first mating portions B812 and one second mating portion B822, so that the adjustment mechanism B800 has at least a first locked state and a second locked state. In other alternative embodiments, there are at least two first mating portions B812 and at least two second mating portions B822, so that the adjustment mechanism B800 has at least three seat width adjustment positions, thereby enabling the child carrier B1000 to better meet the seating width requirements of infants and young children. In still other alternative embodiments, one of the first mating portion B812 and the second mating portion B822 is one and the other is multiple, also enabling the adjustment mechanism B800 to have multiple seat width adjustment positions.

[0305] Reference Figure 37 In this embodiment, the first adjustment strap B811 and the second adjustment strap B821 are each made of woven fabric. The first mating portion B812 is, for example, a connecting buckle, which is secured to the first adjustment strap B811 by, for example, sewing. The second mating portion B822 is, for example, a buttonhole provided through the second adjustment strap B821. In an alternative embodiment, the second mating portion B822 and the first mating portion B812 are, for example, snap fasteners that can be interlocked. In another alternative embodiment, the second mating portion B822 is, for example, a hook, and the first mating portion B812 is, for example, a hook adapted to be hooked onto the hook.

[0306] like Figures 36 to 38As shown, the two first adjustment members B810 and the two second adjustment members B820 are at least partially located on the front of the carrier assembly B200. The carrier assembly B200 is also provided with a shielding member B920, which is connected to the front of the carrier assembly B200 to cover the first adjustment member B810 and the second adjustment member B820, thereby making the front of the child carrier B1000 neater and more beautiful. At least a portion of the shielding member B920 in the depth direction is not connected to the carrier assembly B200, so that an operating port B921 is formed between the shielding member B920 and the carrier assembly B200, thereby allowing the first adjustment member B810 and the second adjustment member B820 to be operated through the operating port. The size of the operating port is suitable for the user to insert his hand to facilitate the operation of the first adjustment member B810 and the second adjustment member B820.

[0307] Example 5

[0308] The fifth embodiment of the present disclosure provides a child carrier B1000, such as Figure 39 As shown, the child carrier B1000 includes a waist belt B120, shoulder straps B110, a carrier assembly B200 connected to the waist belt B120 and shoulder straps B110, and a leg support B230 connected to the carrier assembly B200. The shoulder straps B110 are arranged generally along the depth direction of the carrier assembly B200. One side of the carrier assembly B200 is connected to the waist belt B120, and the side of the carrier assembly B200 away from the waist belt B120 is detachably connected to the shoulder straps B110. In other words, the upper side of the carrier assembly B200 is connected to the shoulder straps B110, and the lower side of the carrier assembly B200 is connected to the waist belt B120. The portion of the carrier assembly B200 near the waist belt B120 forms the hip support B210, and the upper side of the carrier assembly B200 forms the torso support B220. The leg support B230 is connected to the hip support B210 and together with the leg support B230 forms a seat B6 for supporting an infant or young child. The leg support B230 is switchable between an extended state and a retracted state. When the leg support B230 is in the extended state, it moves away from the hip support B210 in the lateral width of the support assembly B200, allowing the seat B6 to have a larger width. When the leg support B230 is in the retracted state, it moves closer to the hip support B210 in the lateral width of the support assembly B200, allowing the seat B6 to have a smaller width.

[0309] This embodiment differs from the aforementioned fourth embodiment in at least the following ways.

[0310] like Figure 39 and Figure 40As shown, the first connection end B231 of one of the two leg support parts B230 is adapted to be connected to the first connection end B231 of the other leg support part B230 via an adjustment mechanism B800. The adjustment mechanism B800 includes a first adjustment member B810 and a second adjustment member B820. The first adjustment member B810 includes a first adjustment strap B811 and a first mating portion B812 disposed on the first adjustment strap B811. One end of the first adjustment strap B811 is connected to the movable end B231a of the first leg support part B230e, while the other end is a movable end and is provided with the first mating portion B812. The second adjustment member B820 includes a second adjustment strap B821 and a second mating portion B822 disposed on the second adjustment strap B821. One end of the second adjustment strap B821 is connected to the movable end B231a of the second leg support part B230f, while the other end is a movable end and is provided with the second mating portion B822.

[0311] Reference Figure 39 and Figure 40The carrier assembly B200 is also provided with a shielding member B920. The shielding member B920 is connected to the front of the carrier assembly B200 to cover the first adjustment member B810 and the second adjustment member B820, thereby making the front of the child carrier B1000 neater and more beautiful. In this embodiment, the carrier assembly B200 and the shielding member B920 are also provided with a limiting channel B924 and an operating port B921 connected to the limiting channel B924 to facilitate operation of the first adjustment member B810 and the second adjustment member B820 through the operating port B921. The operating port B921 is located between the two connecting ports of the limiting channel B924, that is, the operating port B921 is located approximately in the middle of the carrier assembly B200 and the shielding member B920 in the horizontal direction and is connected to the limiting channel B924. A limiting channel B924 is formed between the shielding member B920 and the carrying assembly B200, or formed within the shielding member B920, and the first operating assembly and the second operating assembly are respectively arranged in the limiting channel B924. The limiting channel B924 is formed as a channel that penetrates in the horizontal width direction. In this embodiment, the shielding member B920 is sewn onto the carrying assembly B200. A first stitching line B926 and a second stitching line B927 are provided between the shielding member B920 and the carrying assembly B200. The first stitching line B926 is farther away from the waistband B120 than the second stitching line B927 (that is, the second stitching line B927 is located below the first stitching line B926). A limiting channel B924 is formed between the first stitching line B926 and the second stitching line B927 to confine the first adjustment member B810 and the second adjustment member B820 within the limiting channel B924. The first and second sutures B926 and B927 extend approximately linearly in the widthwise direction. The first suture B926 comprises at least two discontinuous segments, with an access opening B921 formed between the adjacent segments. In this embodiment, the access opening B921 is located on the side of the carrier assembly B200 and shielding member B920 near the torso support portion B220.

[0312] Example 6

[0313] The sixth embodiment of the present disclosure provides a child carrier B1000, such as Figure 41As shown, the child carrier B1000 includes a waist belt B120, shoulder straps B110, a carrier assembly B200 connected to the waist belt B120 and shoulder straps B110, and a leg support B230 connected to the carrier assembly B200. The shoulder straps B110 are arranged generally along the depth direction of the carrier assembly B200. One side of the carrier assembly B200 is connected to the waist belt B120, and the side of the carrier assembly B200 away from the waist belt B120 is detachably connected to the shoulder straps B110. In other words, the upper side of the carrier assembly B200 is connected to the shoulder straps B110, and the lower side of the carrier assembly B200 is connected to the waist belt B120. The portion of the carrier assembly B200 near the waist belt B120 forms the hip support B210, and the upper side of the carrier assembly B200 forms the torso support B220. The leg support B230 is connected to the hip support B210 and together with the leg support B230 forms a seat B6 for supporting an infant or young child. The leg support B230 is switchable between an extended state and a retracted state. When the leg support B230 is in the extended state, it moves away from the hip support B210 in the lateral width of the support assembly B200, allowing the seat B6 to have a larger width. When the leg support B230 is in the retracted state, it moves closer to the hip support B210 in the lateral width of the support assembly B200, allowing the seat B6 to have a smaller width.

[0314] This embodiment differs from the child carrier B1000 in the aforementioned third embodiment in at least the following ways.

[0315] like Figures 41 to 44 As shown, the child carrier B1000 is further provided with an adjustment mechanism B800, which is provided on the leg support portion B230. The adjustment mechanism B800 allows the leg support portion B230 to be switched between an expanded state and a collapsed state by adjusting the leg support portion B230, thereby adjusting the width of the seat portion B6. The adjustment mechanism B800 has an open state and a closed state. When the adjustment mechanism B800 is in the open state, the leg support portion B230 is collapsed, the outer edge B236 of the leg support portion B230 is extended, and at least a portion of the outer edge B236 of the leg support portion does not generate supporting force. A portion of the leg support portion B230 and the hip support portion B210 together form the seat portion B6, reducing the effective width of the leg support portion B230 and thus reducing the width of the seat portion B6. When the adjustment mechanism B800 is in a locked state, the leg support portion B230 is in an expanded state, and the outer edge B236 of the leg support portion is shortened. The outer edge B236 of the leg support portion is suitable for generating a supporting force to support an infant riding on the child carrier B1000. The leg support portion B230 and the hip support portion B210 together form a seat portion B6, and the effective width of the leg support portion B230 is increased, so that the seat portion B6 has a larger width.

[0316] There are two leg support parts B230, and each leg support part B230 is provided with an adjustment mechanism B800. For ease of description, the following description will take one leg support part B230 and the adjustment mechanism B800 configured thereon as an example.

[0317] like Figure 42 and Figure 43 As shown, the leg support portion B230 includes a main body piece B230a and an adjustment piece B230b. One end of the main body piece B230a is formed as a first connection end B231, and the other end of the main body piece B230a is formed as a second connection end B232. The first connection end B231 is connected to the support assembly B200, and the second connection end B232 is connected to the support assembly B200 or the waist belt B120. A portion of the adjustment piece B230b near the second connection end B232 is directly connected to the main body piece B230a, while another portion of the adjustment piece B230b near the first connection end B231 (i.e., the adjustment portion B230b1 of the adjustment piece B230b) is connected to the main body piece B230a via a connecting piece B230c.

[0318] Optionally, the leg support portion B230 further includes a connecting piece B230c, which is connected to at least one of the main body piece B230a and the adjustment piece B230b and shields the adjustment mechanism B800. Figure 42 and Figure 43 The tab B230c is connected to the main body panel B230a and the adjustment panel B230b, respectively. The tab B230c shields the adjustment mechanism B800 from the back of the child carrier B1000 to prevent the adjustment mechanism B800 from interfering with the child in the carrier 1000. In some alternative embodiments, the tab B230c is connected to one of the main body panel B230a and the adjustment panel B230b and extends toward the other of the two. It should be noted that "the connecting piece B230c is connected to one of the main piece B230a and the adjustment piece B230b" can be understood as: the connecting piece B230c is integrally formed with one of the main piece B230a and the adjustment piece B230b, or is fixedly connected to one of the main piece B230a and the adjustment piece B230b by methods such as sewing, or is detachably connected to one of the main piece B230a and the adjustment piece B230b by methods such as zippers and snaps.

[0319] The adjustment mechanism B800 includes a first adjustment member B810 provided on the adjustment piece B230b and a second adjustment member B820 provided on the main body piece B230a. The first adjustment member B810 is provided on the adjustment portion B230b1 of the adjustment piece B230b.

[0320] When the first adjustment member B810 and the second adjustment member B820 cooperate with each other (i.e., the adjustment mechanism B800 is in the locked state), the connecting piece B230c is retracted, and the adjustment piece B230b is connected to the main piece B230a in the depth direction to provide support for the thigh. In this way, the seat portion B6 has a larger width.

[0321] When the first adjustment member B810 and the second adjustment member B820 separate, the connecting piece B230c naturally expands. At this point, at least the portion of the adjustment piece B230b where the second adjustment member B820 is located is no longer connected to the main body piece B230a and cannot provide support for the thigh. Thus, only a portion of the leg support portion B230 and the hip support portion B210 together form the seat portion B6, resulting in a smaller width.

[0322] That is to say, in this embodiment, the width of the leg support part B230 that can be used to provide support force (that is, the effective width of the leg support part B230) is adjusted by the adjustment mechanism B800 to change the width of the seat part B6, thereby meeting the requirements of children of different body shapes and different riding methods for the width of the seat part B6.

[0323] The first adjusting member B810 includes a first mating portion B811. The second adjusting member B820 includes a second mating portion B812. The first mating portion B811 is adapted to cooperate with the second mating portion B812 to switch the adjusting mechanism between a locked state and an open state. The first mating portion B811 and the second mating portion B812 are, for example, zippers that can be zipped together. Specifically, the first mating portion B811 is secured to the adjusting piece B230b, for example, by sewing, and the second mating portion B812 is secured to the main body piece B230a, for example, by sewing. In this embodiment, the second mating portion B812 is disposed on the front side of the main body piece B230a (i.e., the side of the main body piece B230a facing away from the infant) and is located near the contact piece B230c. The first mating portion B811 extends approximately along the depth direction over at least a portion of the adjusting piece B230b, while the second mating portion B821 extends approximately along the depth direction over at least a portion of the main body piece B230a. In this embodiment, the first fitting portion B811 roughly extends over half of the adjustment piece B230b, that is, the lower end of the first fitting portion B811 is roughly located in the longitudinal middle of the adjustment piece B230b; the second fitting portion B821 roughly extends over half of the main body piece B230a, that is, the lower end of the second fitting portion B821 is roughly located in the longitudinal middle of the main body piece B230a.

[0324] The operating principle of the child carrier B1000 in this embodiment is as follows.

[0325] When the required width of the seat B6 is relatively large, the adjustment mechanism B800 is kept in a locked state (i.e., the first mating portion B811 and the second mating portion B821 are pulled together). At this time, due to the pulling action of the first mating portion B811 and the second mating portion B821, the part of the adjustment piece B230b that is pulled together (the part provided with the first mating portion B811) also has a certain support strength, which can provide support for the child to sit. At this time, most or even all of the leg support portion B230 can provide support, making the effective width of the leg support portion B230 larger, and thus making the width of the seat B6 relatively larger. At this time, when the elastic member B7 is provided, the width of the seat B6 of the child carrier B1000 can be further adjusted. The adjustment principle and method are the same as those in the first embodiment above, and will not be repeated here.

[0326] When the required width of the seat B6 is relatively small, the adjustment mechanism B800 is switched to the open state (that is, the first fitting part B811 and the second fitting part B821 are pulled apart). At this time, the first fitting part B811 and the second fitting part B821 no longer provide support strength for the opened part of the adjustment piece B230b (the adjustment part B230b1 provided with the first fitting part B811), and at least a part of the leg support part B230 cannot provide supporting force, so that the effective width of the leg support part B230 is smaller, and thus the width of the seat B6 is relatively small.

[0327] In a variation of this embodiment, the leg support portion B230 includes a main body portion B230a, an adjustment portion B230b, and a tab B230c. Tab B230c is connected between the main body portion B230a and the adjustment portion B230b and can be switched between an extended position and a folded and collapsed position. The upper end of the adjustment portion B230b is fixedly connected to the hip support portion B210 or the main body portion B230a. The child carrier B1000 also includes an adjustment mechanism 800 disposed on the leg support portion B230. The adjustment mechanism B800 includes a first adjustment member B810 disposed on the adjustment portion B230b and a second adjustment member B820 disposed on the main body portion B230a. When the first adjustment member B810 and the second adjustment member B820 are not connected, the tab B230c is in an extended position. When the first adjustment member B810 and the second adjustment member B820 are connected, the tab B230c is in a folded and collapsed position. When the required width of the seat B6 is relatively large, the adjustment mechanism B800 is kept in the open state (that is, the first matching part B811 and the second matching part B821 are kept apart). At this time, the connecting piece B230c is unfolded, and the adjustment piece B230b and the connecting piece B230c can both provide support, so that the width of the seat B6 is relatively large; and when the required width of the seat B6 is relatively small, the adjustment mechanism B800 is switched to the locked state (that is, the first matching part B811 and the second matching part B821 are pulled together). At this time, the adjustment piece B230b can provide support, but the connecting piece B230c cannot provide support due to being folded and retracted, so that the width of the seat B6 is relatively small.

[0328] Example 7

[0329] The seventh embodiment of the present disclosure provides a child carrier B1000, such as Figures 45 to 47 As shown, the child carrier B1000 includes a waist belt B120, shoulder straps B110, a carrier assembly B200 connected to the waist belt B120 and shoulder straps B110, and a leg support B230 connected to the carrier assembly B200. The shoulder straps B110 are arranged generally along the depth direction of the carrier assembly B200. One side of the carrier assembly B200 is connected to the waist belt B120, and the side of the carrier assembly B200 away from the waist belt B120 is detachably connected to the shoulder straps B110. In other words, the upper side of the carrier assembly B200 is connected to the shoulder straps B110, and the lower side of the carrier assembly B200 is connected to the waist belt B120. The portion of the carrier assembly B200 near the waist belt B120 forms the hip support B210, and the upper side of the carrier assembly B200 forms the torso support B220. The leg support portion B230 is connected to the hip support portion B210 and together with the leg support portion B230 forms a seat portion B6 for supporting an infant.

[0330] This embodiment differs from the third embodiment described above in at least the following ways.

[0331] like Figures 45 to 47 As shown, the leg support portion B230 is in the unfolded state (refer to Figure 45 and Figure 47 ) and collapsed state (refer to Figure 46 ) can be switched between. When the leg support part B230 is in the expanded state, the outer edge B236 of the leg support part is farther away from the hip support part B210 in the lateral width direction of the load-bearing component B200, so that the seat part B6 has a larger width. When the leg support part B230 is in the folded state, the outer edge B236 of the leg support part is closer to the hip support part B210 in the lateral width direction of the load-bearing component B200, so that the seat part B6 has a smaller width. There are two leg support parts B230, and the two leg support parts B230 are symmetrically arranged on the left and right sides of the hip support part B210. Each leg support part B230 includes a first side B238 close to the hip support part B210 and a second side B239 away from the hip support part B210. The second side B239 forms the outer edge B236 of the leg support part. The first side B238 is connected to the hip support part B210 by, for example, sewing. The child carrier B1000 is provided with an adjustment mechanism B800 for adjusting the position of the outer edge B236 of the leg support portion relative to the hip support portion B210 to switch the leg support portion B230 between an expanded state and a collapsed state, thereby adjusting the width of the seat portion B6.

[0332] The adjustment mechanism B800 includes a first adjustment member B810 and a second adjustment member B820. The first adjustment member B810 is connected to the first leg support portion B230e, and the first adjustment member B810 is connected to the second leg support portion B230f. The first adjustment member B810 includes a first adjustment strap B811 and a first mating portion B812. One end of the first adjustment strap B811 is connected to the corresponding leg support portion B230 and forms a first fixed end B8111. The other end of the first adjustment strap B811 is a first adjustment end B8112 and is provided with a first mating portion B812. The first fixed end B8111 is away from the first side B238 of the corresponding leg support portion B230 and is connected to the approximately middle of the depth of the corresponding leg support portion B230. The second adjustment member B820 includes a second adjustment strap B821 and a second mating portion B822 disposed on the second adjustment strap B821. One end of the second adjustment strap B821 is connected to the corresponding leg support portion B230 and forms a second fixed end B8211. The other end of the second adjustment strap B821 forms a second adjustment end B8212 and is provided with a second mating portion B822. The second fixed end B8211 is spaced away from the second side B238 of the corresponding leg support portion B230 and is connected to the approximately middle depth of the corresponding leg support portion B230. The second mating portion B822 is adapted to mate with the first mating portion B812 to removably connect the first adjustment strap B811 and the second adjustment strap B821, thereby enabling the adjustment mechanism to switch between an open state and a locked state.

[0333] Optionally, the adjustment mechanism B800 further includes a fixing member B830, which is disposed on the hip support portion B210. The first adjustment strap B811 is further provided with a first adapter B815, which is adapted to connect with the fixing member B830, thereby securing the first adjustment strap B811 to the hip support portion B210. The first mating portion B812 and the first adapter B815 are respectively disposed on the two side surfaces of the first adjustment end B8112. Specifically, the first mating portion B812 is disposed on the front surface of the first adjustment end B8112 and is adapted to be mated with the second mating portion B822. The first adapter B815 is disposed on the back surface of the first adjustment strap B811 and is adapted to be mated with the fixing member B830. The second mating portion B822 is disposed on the back surface of the second adjustment end B8212. When the first adjustment strap B811 is connected to the second adjustment strap B821 and to the fixing member B830 (i.e., the adjustment mechanism B800 is in a locked state), the leg support portion B230 is in a retracted state, and the seat portion B6 has a smaller width. When the first adjustment strap B811 is separated from the second adjustment strap B821 and from the fixing member B830 (i.e., the adjustment mechanism B800 is in an open state), the leg support portion B230 is in an extended state, so that the seat portion B6 has a larger width. Optionally, the dimension of the fixing member B830 in the transverse direction is larger than the dimension of the first adapter B815 in the transverse direction, so that the first adapter B815 can be connected to the fixing member at different positions, thereby adjusting the width of the seat portion B6.

[0334] In an alternative embodiment, the first fixed end B8111 of the first adjustment strap B811 is provided with a first engaging portion B812, and the second fixed end B8211 of the second adjustment strap B821 is provided with a second engaging portion B822. A fixing member B830 is provided on the hip support portion B210, with the first engaging portion B812 and the second engaging portion B822 each adapted to connect to the fixing member B830. In other words, in this embodiment, the first adjustment strap B811 and the second adjustment strap B821 are not directly connected, but are both connected to the fixing member B830. Specifically, the first engaging portion B812 is provided on the backside of the first fixed end B8111, and the second adjustment strap B821 is provided on the backside of the second fixed end B8211. In this case, if desired, one of the first adjustment strap B811 and the second adjustment strap B821 can be connected to the fixing member B830 to allow the leg support portion B230 on one side to be retracted and have a smaller width.

[0335] Reference Figures 45 to 47In this embodiment, the first matching portion B812 and the second matching portion B822 are, for example, Velcro that can be bonded to each other. The first adapter B815 and the fixing member B830 are, for example, Velcro that can be bonded to each other. In some alternative embodiments, the first matching portion B812 and the second matching portion B822 are snaps that can be snapped together; or, the first matching portion B812 is a hook, and the second matching portion B822 is a loop that cooperates with the hook. The first adapter B815 and the fixing member B830 are snaps that can be snapped together; or, the first adapter B815 is a hook, and the fixing member B830 is a loop that cooperates with the hook.

[0336] Each leg support portion B230 is provided with an adjustment channel B23b, which extends along the horizontal width direction and is provided with a connecting port at a position away from the second side B239 (that is, at the first side B238). The first adjustment belt B811 and the second adjustment belt B821 are respectively passed through the corresponding adjustment channel B23b and out of the corresponding connecting port.

[0337] In an alternative embodiment, at least a portion of the leg support portion B230 between the first connection end B231 and the second connection end B232 is disconnected from the hip support portion B210, such that at least a portion of the leg support portion B230 (i.e., the middle portion of the leg support portion B230 in the depth direction) is spaced apart from the hip support portion B210 and forms an adjustment opening B235. Optionally, the leg support portion B230 and the hip support portion B210 are connected by an elastic member B7, which at least partially covers the adjustment opening B235. The elastic member B7 is switchable between an extended state and a non-extended state, allowing the leg support portion B230 to expand or contract relative to the hip support portion B210 (i.e., enabling the edge line 236 of the leg support portion B230 to move away from or closer to the hip support portion B210).

[0338] The child carrier B1000 in this embodiment is detachably connected via a first adjustment strap B811 and a second adjustment strap B821. This allows the outer edge B236 of the leg support portion to be moved closer to or further from the hip support portion B210, thereby relatively contracting or expanding the leg support portion B230. This adjusts the width of the leg support portion B230, and thus the seat portion B6. The adjustment mechanism B800 of the child carrier B1000 provided in this embodiment is simple in structure, easy to adjust, and effectively adjusts the width of the seat portion B6.
