Description

baby carrier

The present invention relates to the technical field of infant and toddler products, and in particular to a baby carrier with an adjustable seat position.

The advent of baby slings (such as baby carriers and waist stools) allows caregivers to free their hands while slinging infants without sacrificing close contact with them. For example, baby carriers can be categorized by holding method, including horizontal, front-facing, face-to-face, and back-carrying.

The design of a baby carrier must not only be ergonomic to reduce the user's burden, but also provide support for the baby's hips, waist, neck, and head, avoiding bending and unnecessary pressure. This ensures the baby's comfort and safety, protecting their delicate muscles and bones. Existing baby carriers create a fixed seating space. However, the seating space required varies, particularly in terms of seat width and height, depending on the age of the child, the age of the same child, and the way the child is held. However, existing baby carriers lack adaptive seat adjustment, compromising comfort and safety.

Therefore, it is necessary to provide a baby carrier that can conveniently and adaptively adjust the infant's sitting position to solve the problems existing in the above-mentioned prior art.

On the other hand, baby carriers have become a common method of transporting infants. However, most existing baby carriers have a drawback: the seat portion of the carrier is a fixed size. Therefore, as the baby grows, the seat portion of the carrier may become too small, reducing the baby's comfort. Alternatively, the seat portion of the carrier, designed to support larger infants, may be too large for younger infants. The carrier may not conform to the baby's physiology, thus failing to provide effective support for smaller infants and even causing the baby to accidentally fall out. Furthermore, the fixed seat portion of conventional baby carriers limits the adaptability of the baby carrier, i.e., the baby carrier cannot be easily and quickly adjusted between front-carry and back-carry configurations.

Therefore, there is an urgent need to provide a baby carrier with an adjustable seat height that can be easily and quickly adjusted to suit infants of different body shapes to achieve optimal use.

The object of the present invention is to provide a baby carrier that can conveniently and adaptively adjust the sitting position of an infant.

To achieve the above-mentioned object, the technical solution of the present invention provides a baby carrier, which comprises: a waist belt; a support piece fixed to the waist belt; shoulder straps arranged along the longitudinal direction of the support piece and connected thereto, wherein the end of the support piece near the waist belt forms a seat for supporting the infant; and a height adjustment assembly, comprising a first connecting member, a second connecting member and a third connecting member, wherein the first connecting member, the second connecting member and the third connecting member are connected to each other in a longitudinal direction of the support piece. The seat portion is arranged in a row at the lower portion of the support plate and the front end of the waist belt; wherein the seat portion switches between an extended position and a folded position by changing its connection relationship with the height adjustment assembly; wherein the seat portion and the height adjustment assembly have a first connection relationship and a second connection relationship, wherein the first connection relationship causes the seat portion to assume the extended position, and the second connection relationship causes the seat portion to assume the folded position.

According to one embodiment, the height adjustment component is Velcro, the second connector is a Velcro male buckle, and the first connector and the third connector are Velcro female buckles.

According to one embodiment, the first connector and the second connector are disposed at the lower portion of the support plate, and the third connector is disposed at the front end of the waist belt.

According to one embodiment, the support plate raises the seat portion to the folded position by engaging the first connector and the second connector disposed on the support plate.

According to one embodiment, the support plate lowers the height of the seat portion by buckling the second connector provided on the support plate with the third connector provided on the waist belt, so that the seat portion is in the extended position.

Another technical solution of the present invention provides a baby carrier comprising: a waist belt; a support plate secured to the waist belt; shoulder straps disposed along the longitudinal direction of the support plate and connected thereto, wherein the support plate, at one end proximal to the waist belt, forms a seat for supporting an infant; and a height adjustment assembly, the seat being detachably connected to the height adjustment assembly; wherein the seat is switchable between an extended position and a collapsed position by changing its connection with the height adjustment assembly; wherein the seat is connected to the height adjustment assembly in a first connection relationship, and the height adjustment assembly is detached from the seat in a second connection relationship; the first connection relationship causes the seat to be in the collapsed position, and the second connection relationship causes the seat to be in the extended position.

According to one embodiment, the height adjustment assembly is disposed on the inner side of the support plate.

According to one embodiment, the height adjustment assembly includes a connecting plate, one end of which is detachably connected to the shoulder strap, and the other end of which is detachably connected to the upper portion of the support plate.

According to one embodiment, the front end of the shoulder strap is provided with a fixing member, and the fixing member is fixedly connected to the front ends of the two shoulder straps.

According to one embodiment, the rear end of the shoulder strap is connected to a webbing structure, and the webbing structure is fixedly connected to the two ends of the fixing member respectively.

The embodiments of the present invention are now described with reference to the accompanying drawings, in which like element numbers represent like elements.

First, referring to Figures 1-19, the baby carrier 1100 provided by the present invention includes a waist belt 1110, a support panel 1120 secured to the waist belt 1110, shoulder straps 1130 extending longitudinally along and connected to the support panel 1120, and a width adjustment assembly 1140 and/or a height adjustment assembly 1150. Among them, the end of the support piece 1120 away from the waist belt 1110 is connected to the shoulder strap 1130, that is, the upper end of the support piece 1120 in the longitudinal direction is connected to the shoulder strap 1130, and the end of the support piece 1120 close to the waist belt 1110 forms a seat 1120a for supporting an infant; when the waist belt 1110 and the shoulder strap 1130 are worn by an adult, a space for an infant to sit is formed between the support piece 1120 and the shoulder strap 1130, and the seat 1120a supports the infant and allows the legs of the infant sitting thereon to be separated and located on both sides of the seat 1120a. Furthermore, a width adjustment assembly 1140 is provided on the seat portion 1120a along the width of the support piece 1120. Adjustment of the width adjustment assembly 1140 allows the seat portion 1120a to have a folded position and an extended position in its width direction, thereby adjusting the infant's sitting width. Correspondingly, a height adjustment assembly 1150 is provided on the seat portion 1120a and along the length of the support piece 1120. Adjustment of the height adjustment assembly 1150 allows the seat portion 1120a to have a folded position and an extended position in its height direction, thereby adjusting the infant's sitting height.

1, 6 and 9, in the present invention, the seat portion 1120a specifically includes a buttocks supporting portion 1121, two leg supporting portions 1122 and two connecting pieces 1123. The two leg supporting portions 1122 are symmetrically connected to the two sides of the buttocks supporting portion 1121 in the transverse direction through the two connecting pieces 1123. The leg supporting portion 1122 is used to support the legs of the infant, and the thickness of the connecting piece 1123 is smaller than that of the buttocks supporting portion 1121 and the leg supporting portion 1122. A thinner connecting piece 1123 is provided between the seat portion 1121 and the leg supports 1122. When the seat portion 1120a is folded after width adjustment, the leg supports 1122 lean against the hip supports 1121, squeezing the connecting piece 1123 and folding it. However, the connecting piece 1123 remains relatively thin in the folded position, preventing wrinkles and discomfort to the infant. This ensures that the seat portion 1120a of the baby carrier 1100 combines both adjustability and comfort.

More preferably, the hip support 1121 and leg support 1122 are both provided with a padded layer or filler, thereby providing better support for the infant and making the ride more comfortable. The connecting piece 1123 is made of a single layer of fabric. Thus, the connecting piece 1123 has a single-layer structure, making the thickness of the connecting piece 1123 in the folded position significantly smaller than that of the padded hip support 1121 and leg support 1122, thus preventing discomfort to the infant.

It should be noted that the structure of the rest of the support plate 1120, the structure of the shoulder strap 1130, and the connection between the support plate 1120 and the shoulder strap 1130 are all conventional arrangements well known to those skilled in the art and will not be described in detail here.

It should also be noted that for a support plate 1120 equipped only with the height adjustment assembly 1150, the connecting plate 1123 can be omitted. That is, the leg support 1122 can be directly connected to both sides of the hip support 1121 in the transverse direction.

1-3 , in the present invention, the belt 1110 includes a belt body 1111 and a waist protection plate 1112. The middle portion of the belt body 1111 is fixedly connected to the lower end of the support plate 1120. The head and tail ends of the belt body 1111 are detachably connected for adults to wear or take off. The structure of the belt body 1111 is a conventional setting in this field and will not be described in detail. The waist support piece 1112 is fixed to or detachably connected to the belt body 1111. It is an elongated strip with a filler or filling layer inside. The width of the waist support piece 1112 is greater than the width of the belt body 1111 at its end. When the belt 1110 is worn, the waist support piece 1112 can be padded at the end of the belt body 1111. This increases the contact area between the waist and the adult, making it easier for adults to carry infants and young children.

As shown below in conjunction with Figures 1-2 and 4-9, in the present invention, the width adjustment assembly 1140 includes at least one adjustment unit. Each adjustment unit is arranged along the width of the support piece 1120 and has an attached state and a detached state. When in the attached state, the adjustment unit folds the seat 1120a in its width direction, thereby reducing the width of the seat 1120a. Correspondingly, the height adjustment assembly 1150 is arranged on the inner or outer side of the support piece 1120 and has an attached state and a detached state. When in the attached state, the height adjustment assembly 1150 folds the seat 1120a in its height direction, thereby adjusting the infant's sitting height.

More specifically, when the width adjustment assembly 1140 is provided with multiple adjustment units, the adjustment units are arranged at intervals along the longitudinal direction of the support piece 1120 and/or at intervals along the transverse direction of the support piece 1120.

1-15 , the width adjustment assembly 1140 and the height adjustment assembly 1150 of the baby carrier 1100 of the present invention are described respectively in different embodiments.

Referring to Figures 1-5 , in the first embodiment of the baby carrier 1100 of the present invention, the width adjustment assembly 1140 includes two adjustment units 1140a and 1140b. These two adjustment units 1140a and 1140b are spaced apart on the seat portion 1120a along the longitudinal direction of the support plate 1120. Therefore, during use, the upper adjustment unit 1140a and/or the lower adjustment unit 1140b can be connected, or both adjustment units 1140a and 1140b can be left unconnected, depending on the size of the infant or child or the seating style.

More specifically, the adjustment units 1140a and 1140b have the same structure. Taking the adjustment unit 1140a as an example, the adjustment unit 1140a includes a first adjustment member 1141 and a second adjustment member 1142 that are detachably connected. The first adjustment member 1141 and the second adjustment member 1142 are respectively disposed on the two sides of the seat portion 1120a in the horizontal direction. In this embodiment, the two are preferably connected at the connection position between the connecting piece 1123 and the leg support part 1122. In this way, when the first adjusting piece 1141 and the second adjusting piece 1142 are connected, the two leg support parts 1122 are leaned against the hip support part 1121, so that the seat part 1120a is in a folded position, thereby reducing the width of the seat part 1120a. At this time, the two connecting pieces 1123 are squeezed and are in a folded position, but because the connecting piece 1123 is a single-layer structure or is thinner, its thickness when folded is small, which does not affect the comfort of the infant or toddler. When the first and second adjusting members 1141 and 1142 are disassembled, the seat 1120a is in the extended position, thereby increasing the width of the seat 1120a compared to the folded position.

1-6 , when the baby carrier 1100 of this embodiment is used with a larger infant, and the infant is seated facing the caregiver, the first and second adjustment members 1141, 1142 of the two adjustment units 1140a, 1140b are not engaged. As shown in FIG1 , the seat portion 1120a is in its extended position, achieving maximum width. This provides ample support and envelopment, making the infant more comfortable. If a larger infant sits with his or her back to the caregiver (facing forward), the infant's legs and trunk will require more space to extend. In this case, the first adjusting piece 1141 and the second adjusting piece 1142 of the upper adjusting unit 1140a can be engaged, while the first adjusting piece 1141 and the second adjusting piece 1142 of the lower adjusting unit 1140b can be unlocked, as shown in Figure 4, so that the upper half of the seat 1120a is folded and narrowed, that is, the width of the upper half of the seat 1120a is smaller than the width of its lower half, thereby providing the infant's legs and trunk with more space to extend. If a smaller infant is being carried, the child will typically be carried facing the caregiver. In this case, the first and second adjustment pieces 1141, 1142 of the upper adjustment unit 1140a can be unlocked, while the first and second adjustment pieces 1141, 1142 of the lower adjustment unit 1140b can be engaged, as shown in Figure 5. This folds the lower half of the seat 1120a and narrows it. That is, the width of the lower half of the seat 1120a is smaller than the width of the upper half, creating a seat space that fits smaller infants and better supports their backs.

In this embodiment, the first adjusting member 1141 and the second adjusting member 1142 are preferably male and female buckles of matching plug-in buckles. The male and female buckles can be easily connected and disconnected, thus simplifying the operation when adjusting the width of the seat portion 1120a.

It is understood that the first and second adjusting members 1141 and 1142 are not limited to snap-on buckles. For example, they may also utilize matching snaps, Velcro, zippers, or removable fixed buckles and rings, etc., to similarly adjust the width of the seat portion 1120a.

Referring to Figures 6-8 , in the second embodiment of the baby carrier 1100 of the present invention, the configuration of the two adjustment units 1140a and 1140b is the same as that of the first embodiment described above, with the only difference being the slight difference in the structure of the first adjustment member 1141 and the second adjustment member 1142.

The following explanation uses adjustment unit 1140a as an example. One of the first adjustment member 1141 and the second adjustment member 1142 of adjustment unit 1140a extends along the width of seat 1120a and has a certain length. At least one adjustment section is provided on either first adjustment member 1141 or second adjustment member 1142. Each adjustment section is optionally detachably connected to the other of first adjustment member 1141 and second adjustment member 1142.

In this embodiment, the first adjusting member 1141 has a certain length. One end of the first adjusting member 1141 is connected to the connection point between the connecting piece 1123 on one side of the seat 1120a and the leg support 1122. The other end of the first adjusting member 1141 has at least one fixing hole, of which only one is schematically shown in Figures 6-8. The second adjusting member 1142 is preferably a fixing buckle, which is connected to the connection point between the connecting piece 1123 on the other side of the seat 1120a and the leg support 1122. In this way, when any fixing hole of the first adjusting member 1141 is engaged with the fixing buckle, the seat 1120a is folded, reducing its width.

In this embodiment, the first adjusting member 1141 is preferably, but not limited to, a cloth tape of a certain length, and is provided with at least one fixing hole. Of course, the first adjusting member 1141 is not limited to a cloth tape. Alternatively, the second adjusting member 1142 may be a fixing ring. In this arrangement, multiple fastening elements, such as fixing buckles or buttons, are intermittently connected to the first adjusting member 1141, thus enabling multi-position adjustment of the first adjusting member 1141.

It is understood that the first adjusting member 1141 and the second adjusting member 1142 can also be detachably connected via a matching buckle, snap button, Velcro, zipper, etc.

Referring again to Figures 6-8 , the structure and configuration of adjustment unit 1140b are identical to those of adjustment unit 1140a and will not be repeated. Furthermore, the usage of the baby carrier 1100 in this embodiment is the same as in the first embodiment and will not be repeated.

Referring now to Figure 9, in a third embodiment of the baby carrier 1100 of the present invention, the arrangement of the adjustment units differs from the above two embodiments. In this embodiment, there are four adjustment units. Two adjustment units 1140a are spaced apart along the width of the support piece 1120 and located above the seat 1120a. In other words, the two adjustment units 1140a are positioned at the same height. The other two adjustment units 1140b are spaced apart along the width of the support piece 1120 and located below the seat 1120a. In other words, the two adjustment units 1140b are positioned at the same height and below the two adjustment units 1140a.

In one specific embodiment, two adjustment units 1140a are symmetrically arranged along the transverse width of the seat 1120a, and two adjustment units 1140b are similarly symmetrically arranged along the transverse width of the seat 1120a. Each adjustment unit has an identical structure. For example, one of the adjustment units 1140a has a first adjustment member 1141 connected to a side of the transverse width of the seat 1120a, specifically at the junction of the leg support 1122 and the connecting piece 1123. The second adjustment member 1142 is connected to the hip support 1121. When the first and second adjustment members 1141 and 1142 are connected, the seat 1120a can be folded, thereby reducing its width. Of course, the connection positions of the first adjusting member 1141 and the second adjusting member 1142 can be interchanged.

In this embodiment, the first and second adjusting members 1141 and 1142 are preferably buckles and fixed buckles, but are not limited to these. They can also be cooperating buckles, snaps, Velcro, zippers, etc. Furthermore, the structure of each adjusting unit can of course be the structure of any of the above embodiments.

9 , when the baby carrier 1100 of this embodiment is in use with a larger infant, if the larger infant sits facing the caregiver, all the adjustment units 1140a and 1140b are not engaged. As shown in FIG9 , the seat 1120a is in the extended position and has the maximum width, thereby providing a larger support and enclosing space, making the infant more comfortable. If a larger infant sits with his back to the caregiver (facing forward), the infant's legs and trunk will require more space to extend. In this case, the first adjusting parts 1141 and the second adjusting parts 1142 of the two upper adjusting units 1140a can be engaged respectively, while the first adjusting parts 1141 and the second adjusting parts 1142 of the two lower adjusting units 1140b are not engaged, so that the upper part of the seat 1120a is folded and narrowed, that is, the width of the upper part of the seat 1120a is smaller than the width of its lower part, thereby allowing the infant's legs and trunk to have more space to extend. If a smaller infant is seated facing the caregiver, the first and second adjustment members 1141 and 1142 of the upper adjustment units 1140a are not engaged, while the first and second adjustment members 1141 and 1142 of the lower adjustment units 1140b are engaged. This causes the lower portion of the seat 1120a to fold and narrow. In other words, the lower portion of the seat 1120a is narrower than the upper portion, creating a seat space that fits smaller infants and provides better back support.

10-19 , the height adjustment assembly 1150 of the baby carrier 1100 of the present invention can be provided in addition to any of the aforementioned embodiments, i.e., the baby carrier 1100 can be provided with both the width adjustment assembly 1140 and the height adjustment assembly 1150. Alternatively, the height adjustment assembly 1150 can be provided separately. Either method does not affect the configuration of the height adjustment assembly 1150. The following describes the different structures of the height adjustment assembly 1150.

Referring to Figures 10-12 , in a fourth embodiment of the baby carrier 1100 of the present invention, a height adjustment assembly 1150 is disposed on the inner side of the support plate 1120 . When in the connected state, the height adjustment assembly 1150 connects to the upper and lower portions of the hip support portion 1121 , respectively. This causes the seat portion 1120a to be folded in its height direction, thereby raising the infant's sitting height.

In this embodiment, the height adjustment assembly 1150 includes a detachably connected third adjustment member 1151 and a fourth adjustment member 1152. Referring to Figure 10 , when the height adjustment assembly 1150 is detached, the third and fourth adjustment members 1151 and 1152 can be positioned vertically on different sides of the hip support 1121. When the third and fourth adjustment members 1151 and 1152 are connected, the hip support 1121 can be folded in its height, thereby raising the infant's sitting height.

More specifically, when the height adjustment assembly 1150 is in the disassembled state shown in FIG10 , the third adjustment member 1151 is, for example, located below the hip support portion 1121 and connected to the support plate 1120, while the fourth adjustment member 1152 is, for example, located above the hip support portion 1121. Depending on the embodiment, the fourth adjustment member 1152 may be connected to the support plate 1120, the waist belt 1110, or the shoulder strap 1130. Thus, when a smaller infant is needed, the third and fourth adjustment members 1151 and 1152 are simply connected, thereby folding the seat 1120a in its vertical direction, as shown in FIG11 . This allows the infant's hip support to be raised, thereby increasing the infant's sitting height for greater comfort. This also creates a seating space tailored to the smaller infant, effectively providing the infant with a comfortable ride. The seat supports the infant to prevent them from accidentally falling. When a caregiver needs to carry a larger infant, they can simply detach the third and fourth adjustment members 1151, 1152, allowing the seat 1120a to be extended in its height direction, as shown in Figure 10. Once the infant is seated, the hip support 1121 is lowered, creating a larger seating space to accommodate larger infants and enhance their comfort.

As shown in Figures 10-11, in this embodiment, a fixing member 1131 is provided at the front end of the shoulder straps 1130. This fixing member 1131 is fixedly connected to the front ends of the two shoulder straps 1130. The fourth adjusting member 1152 is connected to this fixing member 1131. This makes the connection and removal of the third adjusting member 1151 and the fourth adjusting member 1152 more convenient.

In this embodiment, the third and fourth adjusting members 1151 and 1152 are preferably cooperating zippers, which can be easily connected and disconnected, making the adjustment of the infant's sitting height more convenient and quick. Of course, the third and fourth adjusting members 1151 and 1152 are not limited to zippers. They can also be cooperating buckles, snaps, Velcro, or removable fixing buckles and fixing holes.

It should be noted that in this embodiment, the height adjustment assembly 1150 can also be located on the outside of the support plate 1120. In this case, the fourth adjustment member 1152 is located below the hip support portion 1121 and connected to the support plate 1120 or the waist belt 1110.

Furthermore, multiple third adjusting members 1151 and fourth adjusting members 1152 can be provided. In this arrangement, multiple third adjusting members 1151 and/or multiple fourth adjusting members 1152 are spaced apart along the longitudinal direction of the support plate 1120. During use, the third adjusting members 1151 and fourth adjusting members 1152 at certain heights can be connected as needed to achieve multi-level adjustment.

13-16 , the fifth embodiment of the baby carrier 1100 of the present invention differs from the fourth embodiment in that the height adjustment assembly 1150 further includes a height adjustment member 1153, at least one end of which is detachably connected to the third adjustment member 1151 and/or the fourth adjustment member 1152. When the fourth adjustment member 1152 is connected, the hip support 1121 can be folded in its height direction, raising the infant's hip support position and increasing the infant's sitting height. When the height adjustment member 1153 is detached from the third adjustment member 1151 and/or the fourth adjustment member 1152, the hip support 1121 can be naturally extended, thereby lowering the infant's sitting position. The height adjustment member 1153 not only makes adjusting the sitting position more convenient and quick, but also ensures that after adjustment, the height adjustment member 1153 supports the infant's hips, thereby providing a more even support for the infant's hips and improving seating comfort.

In this embodiment, the height adjuster 1153 is detachably connected to the third adjuster 1151 and the fourth adjuster 1152 at its respective ends. Specifically referring to Figures 13-16 , the height adjuster 1153 is provided with a fifth adjuster 1154 detachably connected to the third adjuster 1151 and a sixth adjuster 1155 detachably connected to the fourth adjuster 1152 at its respective ends. Thus, when the third adjuster 1151 is connected to the fifth adjuster 1154 and the fourth adjuster 1152 is connected to the sixth adjuster 1155, the height adjuster 1153 is installed, thereby placing the hip support 1121 in a folded position.

As shown in Figures 15-16, in this embodiment, the front ends of the shoulder straps 1130 are provided with fixing members 1131. Fixing members 1131 are fixedly connected to the front ends of the two shoulder straps 1130. The fourth adjustment member 1152 is connected to the fixing member 1131. Therefore, after the height adjustment member 1153 is installed, its lower end is connected to the shoulder straps 1130.

In this embodiment, the third and fifth adjustment members 1151 and 1154, as well as the fourth and sixth adjustment members 1152 and 1155, are mating zippers. These zippers allow for quick installation and removal of the height adjustment member 1153, making adjustment of the infant's sitting height more convenient and quick. Of course, the height adjustment member 1153 can also be installed using mating buckles, snaps, Velcro, or mating buckles and holes.

Continuing with Figures 13-16, when the baby carrier 1100 of this embodiment is used to carry a smaller infant, the height adjuster 1153 is connected to the third and fourth adjusters 1151, 1152, respectively. As shown in Figure 16, the hip support 1121 is now in a collapsed position in its height direction. The height adjuster 1153 forms the hip support position for the infant, raising the hip support position relative to the waist belt 1110, raising the infant's sitting height, and creating a seating space that fits smaller infants, thereby providing effective support for the infant and preventing them from falling. If an infant accidentally falls, the hip support formed by the height adjuster 1153 becomes flatter and has a larger support area, making the infant more comfortable. If a larger infant is to be carried, the height adjuster 1153 can be removed from the third and fourth adjusters 1151 and 1152, respectively, thereby extending the hip support 1121. As shown in Figure 13, the hip support 1121 is lowered relative to the waist belt 1110 after the infant is seated, creating a larger hip support 1121 to accommodate larger infants and improve their riding comfort.

Referring now to Figures 17-19 , the sixth embodiment of the baby carrier 1100 of the present invention differs from the fourth and fifth embodiments described above in the placement of the height adjustment assembly 1150. In this embodiment, the height adjustment assembly 1150 is located outside the support plate 1120 and includes a detachably connected third adjustment member 1151 and a fourth adjustment member 1152. One of the third adjustment member 1151 and the fourth adjustment member 1152 is provided with a hip support portion 1121.

More specifically, one of the third and fourth adjusting members 1151 and 1152 is positioned on the hip support 1121, while the other is positioned above and/or below the hip support 1121. When the third and fourth adjusting members 1151 and 1152 are connected, the hip support 1121 is folded in its height, thereby adjusting the infant's sitting position.

As shown in Figure 17, in a specific embodiment, the height adjustment assembly 1150 has a third adjustment component 1151 and two fourth adjustment components 1152. The third adjustment component 1151 is arranged on the hip support portion 1121, and the two fourth adjustment components 1152 are respectively arranged above the hip support portion 1121 and at the waist belt 1110. The third adjustment component 1151 and the fourth adjustment component 1152 are arranged at intervals along the longitudinal direction of the support plate 1120, and the third adjustment component 1151 is optionally connected to one of the fourth adjustment components 1152. Specifically, when the third adjustment member 1151 is connected to the fourth adjustment member 1152 above the hip support 1121, as shown in FIG18 , the hip support 1121 is in a folded position in its height direction. This raises the infant's hip support relative to the waist belt 1110, increasing the infant's sitting height and making the infant more comfortable. At the same time, a seating space that fits smaller infants is created, making it easier for the infant to sit comfortably. When carrying a smaller infant, the third adjuster 1151 is connected to the fourth adjuster 1152 above the waist belt 1110, as shown in Figure 19 . This allows the hip support 1121 to be extended in its height direction, lowering the infant's hip support. This lowers the infant's sitting height, creating a larger seating space to accommodate larger infants and improve their comfort.

It is understood that the number of fourth adjustment members 1152 is not limited to two. Multiple fourth adjustment members 1152 can be provided above and below the hip support 1121, respectively, so that the third adjustment member 1151 can be selectively connected to any fourth adjustment member 1152, thereby achieving multi-level adjustment. Correspondingly, multiple third adjustment members 1151 can be provided on the hip support 1121, with third adjustment members 1151 at different heights selectively connected to the fourth adjustment member 1152 above or below, similarly achieving multi-level adjustment.

In this embodiment, the third and fourth adjusting members 1151 and 1152 are mating male and female Velcro buckles. Velcro makes height adjustment easier and more labor-saving. Of course, the third and fourth adjusting members 1151 and 1152 are not limited to Velcro. They can also utilize mating snap buckles, snaps, zippers, or mating fixing buckles and fixing holes.

As shown in the combined figures, in the fourth, fifth, and sixth embodiments, if the width of the hip support 1121 needs to be adjusted, it can be adjusted in the same manner as in the first to third embodiments. For example, in the sixth embodiment, the structural arrangement of the seat 1120a is the same as that of the first embodiment, namely, the seat 1120a comprises a hip support 1121, two leg supports 1122, and two connecting pieces 1123. Furthermore, the seat 1120a is equipped with a width adjustment assembly 1140 according to any of the first to third embodiments. Therefore, the width and/or height of the seat 1120a can be selectively adjusted to adjust the infant's sitting height and/or sitting width.

In summary, since the baby carrier 1100 of the present invention is provided with a width adjustment component 1140 and/or a height adjustment component 1150 on the seat portion 1120a of the support plate 1120, the height adjustment component 1150 can be adjusted to adjust the sitting height of the baby or/and the width adjustment component 1140 can be adjusted to adjust the sitting width of the baby according to different body shapes of the baby or different riding styles, so that the seat portion 1120a can be adjusted to adjust the sitting height of the baby. The space between the seat 1120a and the baby carrier can create a snug fit for smaller infants, or neither can be adjusted to create a larger seating space, effectively supporting larger infants. In other words, the size of the seat 1120a of the baby carrier 1100 of the present invention can be quickly and easily adjusted to suit different needs, achieving optimal use and ensuring the safety and comfort of the infant.

The structure and connection methods of the baby carrier 1100 not described in detail are conventional configurations well known to those skilled in the art and will not be described in detail here.

The seventh embodiment of the present invention will now be described.

As shown in Figures 20-24 , a seventh embodiment of the present invention, a height-adjustable baby carrier 2100, includes a wearable carrying assembly 2001 and a support panel 2002 connected to the carrying assembly 2001 for carrying a baby.

More specifically, the front ends of the shoulder straps 2012 are provided with fixing members 2121, which are fixedly connected to the front ends of the shoulder straps 2012. More specifically, the two ends of the connecting piece 2311 are detachably connected to the fixing members 2121 and the upper portion of the support plate 2002, respectively, via a zipper structure 2312. More specifically, the rear end of each shoulder strap 2012 is connected to a webbing structure 2122. More specifically, the webbing structures 2122 at the rear ends of the two shoulder straps 2012 are fixedly connected to the two ends of the fixing member 2121.

When in use, when a caregiver needs to carry a smaller baby, he or she only needs to close and connect the connecting piece 2311 to the fixing piece 2121 and the upper part of the supporting piece 2002 through the zipper structure 2312. At this time, the connecting piece 2311 and the seat 2003 are in a first connection relationship, so that the seat 2003 of the baby carrier 2100 with adjustable seat height is in a folded position, and the baby's hip support position becomes higher, forming a seat space that fits smaller babies, thereby allowing the baby to obtain effective support. Preventing babies from accidentally falling; when a caregiver needs to carry a larger baby, they simply remove the connecting piece 2311 from the seat 2003 via the zipper structure 2312. The connecting piece 2311 and the seat 2003 are now in a second connection relationship, allowing the seat 2003 of the height-adjustable baby carrier 2100 to be extended, lowering the baby's hip support. This creates a larger seat space to accommodate larger babies and improve their comfort.

The eighth embodiment of the present invention is now described.

25-27 , the eighth embodiment of the baby carrier 2100 with adjustable seat height includes a carrying assembly 2001 wearable on a user and a support plate 2002 connected to the carrying assembly 2001 for carrying a baby. The backpack assembly 2001 includes a waist belt 2011 and two shoulder straps 2012. The front ends of the shoulder straps 2012 are connected to the upper portion of the support plate 2002, while the rear ends of the shoulder straps 2012 are connected to the middle portion of the support plate 2002. The lower portion of the support plate 2002 and the backpack assembly 2001 enclose a seat 2003 for the infant. The seat 2003 is equipped with a height adjustment assembly 2031. The seat 2003 has an extended position and a stowed position, respectively, with the extended position being lower than the stowed position.

When using the baby carrier 2100, a caregiver simply snaps the female Velcro buckle of the first connecting member 2313a and the male Velcro buckle of the second connecting member 2313b on the support plate 2002 together. The first and second connecting members 2313a, 2313b, are now in a first connection with the seat 2003. This causes the seat 2003 of the height-adjustable baby carrier 2100 to be folded, raising the infant's hip support position and creating a seat space that fits smaller infants. This effectively supports the infant and prevents them from accidentally falling. When a caregiver needs to carry a larger baby, they simply snap together the Velcro male buckle of the second connecting piece 2313b on the support plate 2002 and the Velcro female buckle of the third connecting piece 2313c on the waist belt 2011. The second and third connecting pieces 2313b, 2313c, are now in a second connection relationship with the seat 2003. This places the seat 2003 of the height-adjustable baby carrier 2100 in an extended position, lowering the baby's hip support. This creates a larger seat space to accommodate larger babies and improve their comfort.

20 to 27 , the baby carrier 2100 of the present invention has an adjustable seat height, and the seat 2003 is provided with a height adjustment assembly 2031. The seat 2003 has relative extended and folded positions through the height adjustment assembly 2031. The size of the seat 2003 can be conveniently and quickly adjusted to suit infants of different body shapes to achieve the best usage state. For young infants, the infant is smaller in size, and the seat 2003 is in the folded position by being connected to the height adjustment assembly 2031, so that the infant's buttocks support position becomes higher, forming a seat space that fits smaller infants, thereby providing effective support for the infant and preventing the infant from accidentally falling. As the baby grows, the seat 2003 becomes larger. By removing the height adjustment assembly 2031, the seat 2003 is placed in the extended position, lowering the baby's hip support position. This creates a larger seat space to accommodate larger babies.
