Description

Technical Field

[0001] This utility model relates to the field of maternal and infant products technology, specifically to a multifunctional waist stool. Background Technology

[0002] Parents often need to run errands while caring for infants and toddlers, such as shopping, grocery shopping, or traveling. For the safety of their children, especially newborns, they usually choose to bring their babies along. Holding a baby in their arms restricts their hands and can easily lead to fatigue. Using a stroller presents challenges such as taking public transportation, going up and down stairs, and still requires both hands to push the stroller. Baby carriers have largely solved these problems, but traditional baby carriers still have certain drawbacks for infants: they lack good ventilation, causing babies to sweat and develop eczema when lying face down; and they are also cumbersome to disassemble and put on quickly. Utility Model Content

[0006] The front end of the lumbar stool is provided with a chest protector, which curves in an arc along the front end of the lumbar stool toward the chest, and the chest protector is connected to the Y-shaped shoulder strap by several straps with quick-release buckles.

[0007] The front end of the Y-shaped shoulder strap is detachably connected to the front waist belt, and the other end extends to connect to the rear waist belt.

[0008] The rear waistband section has a support plate embedded inside.

[0009] In one specific embodiment, the front chest protector is configured to be wider at the top and narrower at the bottom; the four corners of the protector are rounded and the whole is a shell structure; and a heating module is provided inside the front chest protector.

[0010] In a specific embodiment, two sets of straps with quick-release buckles are provided between the front chest protector and the Y-shaped shoulder strap. One set of straps is arranged parallel to the waist belt and is located on the left and right sides at the bottom of the Y-shaped shoulder strap. The other set of straps is connected to the Y-shaped shoulder strap along the top two ends of the front chest protector. The straps include a plug, a buckle, and a strap. The plug is fixed to the open end of the strap, and the buckle is set on the Y-shaped shoulder strap. The plug and the buckle form an insert-type engagement.

[0011] In a specific embodiment, the Y-shaped shoulder strap is an integrated shoulder strap, which includes a head shoulder strap and a tail shoulder strap. The head is connected to the front waistband via a zipper structure. A head insertion hole is provided between the head shoulder strap and the tail shoulder strap, and an elastic band is sewn inside the shoulder strap for fitting onto the user's head. The tail shoulder strap is gathered into a strip shape and connected to the back waistband.

[0012] In one specific embodiment, the front waistband and the rear waistband are connected by straps on both sides and are provided with a tension adjustment structure.

[0013] In one specific embodiment, the lumbar stool seat is shaped by placing an EPP pad and a PU foam pad inside, and a fan is installed on the bottom outer side of the lumbar stool seat; the ventilation fan is driven by a battery and controlled by a main board, the control switch is located on the side of the front waist belt, and the wiring extends along the lumbar stool seat to the front waist belt; the top of the lumbar stool seat is provided with a ventilation opening, which is used by the fan to exhaust cold air from the ventilation opening along the air duct.

[0014] In one specific embodiment, the chest protector includes an outer layer and an inner layer, the inner layer being provided with breathable sponge, the outer layer being covered with a breathable mesh surface, and a heating module being embedded inside.

[0015] In one specific embodiment, the rear waistband is filled with sponge, and a rabbit ear-shaped support plate is added to the rear end of the rear waistband.

[0016] In one specific embodiment, the surface of the tail shoulder strap is provided with scale values ​​to indicate tightness adjustment.

[0017] The beneficial effects of this utility model are as follows:

[0018] 1. The hip seat is positioned at the front of the lumbar support, and its internal design features an arc-shaped fit, ensuring a closer fit between the entire weight-bearing surface and the curves of the waist and hips. This fit not only helps distribute the baby's weight across the parents' lower back but also reduces gaps between the belt and the body, preventing slippage or movement during activity and improving stability and safety.

[0019] 2. The combination of Y-shaped shoulder straps and a front chest protector allows the weight of the baby and the baby to be shared equally on both the shoulders and chest. Ordinary baby carriers often rely solely on the waist belt for support, which can easily lead to lower back fatigue over time. This design features a dedicated load-bearing structure on the shoulders and chest, transferring some of the weight to these areas and further distributing the center of gravity upwards, thus reducing the burden on the lower back.

[0020] The front chest protector curves in an arc along the front of the lumbar support seat towards the chest, which helps to evenly distribute the pressure of the shoulder straps across the chest area, further reducing the pressure on any single point. In addition, the shell-like design of the protector, which is wider at the top and narrower at the bottom, along with the rounded corners, not only fits different body shapes but also reduces friction and pressure on the chest and underarms during wear, improving overall wearing comfort.

[0021] 3. Two sets of quick-release straps are set on the front chest protector and the Y-shaped shoulder straps, which are parallel to the waist belt and distributed on the left and right sides, allowing the user to quickly separate the shoulder straps or protector from the waist belt when needed, realizing the process of "wearing - adjusting - quickly relaxing".

[0022] 4. Install a battery-powered ventilation fan on the outer bottom of the baby carrier seat. The fan can be turned on at any time to provide active ventilation for the baby's bottom through the built-in motherboard, control switches on both sides of the waist belt, and the wiring layout that extends along the baby carrier seat and waist belt.

[0023] The combination of breathable mesh fabric covering the seat surface and multi-layered structure formed by EPP+PU padding inside the seat effectively reduces the stuffiness caused by prolonged sitting or holding in summer or when the baby is very active, reduces the accumulation of heat and moisture on the baby's buttocks, and thus reduces discomfort caused by diaper rash or sweat.

[0047] Example 2

[0048] This embodiment provides a multifunctional lumbar support stool, which includes: a Y-shaped shoulder strap 1, a front chest protector 2, a lumbar support seat 3, a front lumbar belt 4, and a rear lumbar belt 5. The structure of each component and their interconnection are as follows:

[0049] The lumbar support seat 3 fits against the front lumbar belt part 4. The lumbar support seat 3 is located at the front end of the front lumbar belt part 4, and its inner side fits against the front lumbar belt part 4 in an arc shape along the curve of the human waist and hip.

[0050] The baby carrier seat 3 features an internal EPP layer and a PU foam padding layer, ensuring both support and enhanced comfort. This conforming structure distributes localized pressure from the baby's weight while eliminating gaps between the waistband and the body, preventing slippage or movement during walking or bending, thus improving stability and safety.

[0051] The front waist belt 4 and the rear waist belt 5 are connected by a quick-release buckle 6, allowing the user to quickly put on and take off the belt. The belt has an adjustable tension structure (the tension adjustment is a common type of belt adjustment structure shown in the figure) to accommodate users of different body types.

[0052] The Y-shaped shoulder strap 1 consists of a head shoulder strap 7 and a tail shoulder strap 8: the front end of the head shoulder strap 7 is detachably connected to the front waist belt 4 via a zipper structure 9; an elastic band is sewn in the middle of the shoulder strap, and a head insertion hole 10 is provided, which makes it convenient for the user to put the shoulder strap on the head and free their hands; the tail shoulder strap 8 is gathered into a strip and extends to the back waist belt 5, and is provided with scale values ​​to indicate the user to adjust the tightness.

[0053] The front chest protector 2 is located at the front end of the lumbar support seat 3, extending upwards in an arc to the chest, with a shell structure that is wider at the top and narrower at the bottom, and rounded corners. The front chest protector 2 is lined with breathable sponge and has an embedded electrically heated module 11, which the user can turn on to enhance warmth.

[0056] The second set of straps extends from both ends of the top of the protective plate and is inserted into the shoulder strap buckle.

[0057] This design allows users to quickly separate the shoulder strap from the brace when needed, completing the "wearing-adjusting-quick relaxation" process.

[0058] A miniature fan 13, powered by a battery and controlled by a mainboard, is installed on the outer side of the bottom of the baby seat 3. The control switch 14 is located on the side of the front waist belt 4, with wiring arranged along the seat and waist belt to the switch. A ventilation opening is located at the top of the seat. When the fan is turned on, cool air is expelled through the ventilation opening along the built-in air duct, providing active ventilation for the baby's bottom. Combined with the breathable mesh fabric on the surface and the internal EPP+PU multi-layer composite structure, this effectively reduces stuffiness and sweat buildup, minimizing diaper rash and discomfort caused by heat and moisture.

[0059] Switches are sewn on the corresponding positions on both sides of the outside of the belt, with only the button heads exposed to prevent accidental contact with sand and dust.

[0060] How to use:

[0061] Adjust before wearing

[0062] The user first opens the belt, then places it tightly against the waist, positioning the steel plate at the back of the belt in the center of the spine, with the front of the lumbar support seat facing forward.

[0063] Adjust the elastic bands on both sides of the belt to fit the waist. After the belt is fastened, it should fit snugly but not compressively.

[0064] Wrap the Y-shaped shoulder straps 3 around your shoulders from behind, ensuring the split is in the middle of your shoulder blades. The front ends of the shoulder straps are already sewn to the front of the waist belt. Place the front chest protectors 4 on both sides of your chest.

[0065] Place the baby in the hip seat.

[0066] After confirming that the shoulder straps and chest protector are secured and the waist belt is fastened, gently separate the baby's legs naturally so that the buttocks are facing the center of the hip seat. Thread the top straps of the protector into the holes in the middle of the shoulder straps, and then fasten the quick-release straps at the bottom of the protector to the quick-release straps at the bottom of the shoulder straps.

[0067] Sit your baby in the seat with their legs bent into an "M" shape and their feet turned outwards and dangling on either side of the seat, so that their spine naturally fits against the user's abdomen.

[0068] Once the baby is seated securely, the user can lean forward slightly to give the baby a feeling of being close to the back. The shoulder straps and chest protector will distribute about 30%–40% of the weight, while the remaining 60%–70% will be borne by the lumbar support and the seat.

[0069] Depending on the usage scenario, the length of the sliding buckle at the end of the shoulder strap can be adjusted as needed to slightly tighten or loosen the shoulder strap, ensuring that the baby fits snugly against the user's body and maintains a stable sitting posture.

[0070] Turn on the ventilation system

[0071] Depending on the ambient temperature and your own needs, you can turn up the control switches on both sides of the waist belt to provide appropriate airflow for the baby and lower back, and improve the breathability.
