Description

Technical Field

[0001] The utility model relates to the technical field of child safety seats, and particularly relates to a layered cushion structure. Background Art

[0002] At present, to ensure the safety of children in the car, child safety seats are generally installed on car seats for children to sit on. During driving, children are restrained in the safety seats. When the vehicle speed changes, the driving direction changes, or an accident occurs, children are continuously fixed in the child safety seats to avoid or reduce the injuries suffered by children. According to the statistical analysis of the World Health Organization, the correct use of child car safety seats can reduce the traffic accident mortality rate by 70%.

[0003] To save expenses, users usually choose child safety seats that can be used across different groups. The existing safety seats generally adjust the angle between the seat cushion and the backrest to realize the mutual conversion between the upright state and the lying state of the child seat, so as to be applicable to children of different ages, realize the multi-functional use of one seat, and then realize the cross-group universality of child safety seats.

[0004] For example, a seat lying adjustment mechanism and a child safety seat disclosed in a Chinese utility model patent (publication number: CN210174682U) are used to adjust a seat cushion and a backrest plate that are hinged to each other. Among them, one side of the seat cushion far from the hinged part with the backrest plate is fixed. The seat lying adjustment mechanism includes a backrest plate pulling component and a seat belt guiding component; the backrest plate pulling component includes: a handle, which drives the backrest plate to move along the extension direction of the backrest plate so that the hinged part of the seat cushion and the backrest plate moves obliquely up and down, and a stop block, which is used to limit the handle in the moving position; the seat belt guiding component includes: a pin, which is arranged adjacent to the hinged part of the seat cushion and the backrest plate so that when the hinged part of the seat cushion and the backrest plate moves obliquely up and down, the pin is driven to move up and down. Through the seat lying adjustment structure, the angle between the seat cushion and the backrest plate can be adjusted, so as to realize the mutual conversion between the upright state and the lying state of the child seat, and realize the multi-functional use of one seat.

[0005] However, for a seat lying adjustment mechanism and a child safety seat disclosed in the above prior art, the width of the seat cushion part generally cannot be adjusted, which easily limits the activity space of children, making children feel crowded when sitting, or making the activity space of children relatively loose, resulting in poor wrapping performance for children when sitting, and further resulting in a poor riding experience for children. Therefore, when sitting for a long time, children are prone to physical discomfort and emotional instability, and cannot meet the comfort requirements for children when sitting. At the same time, when the riding space is relatively loose, the wrapping performance for children when sitting is poor, and when the vehicle is running, the lateral shaking amplitude of children is relatively large, which cannot meet the safety requirements for children when sitting.

[0006] Therefore, it is necessary to improve the prior art. Summary of the Utility Model

[0007] The purpose of the present utility model is to provide a layered cushion structure for addressing the defects and deficiencies of the prior art. Through the layered and detachable cushions, the overall thickness of the cushion of the child safety seat can be adjusted to meet the riding needs of children at different stages and with different body shapes. Moreover, the cushion of the child safety seat can be adjusted to better fit the current body shape of the child, which is conducive to improving the riding comfort and safety of the child.

[0008] To achieve the above purpose, the present utility model adopts the following technical solutions:

[0009] A layered cushion structure includes a base cushion, a first cushion, and a second cushion assembly. The base cushion is fixedly arranged on the safety seat. The first cushion is placed on the base cushion, and the second cushion assembly is placed on the first cushion. The second cushion assembly includes an inner pad, a left side guard pad, a right side guard pad, and a head protection pad that are detachably connected to the inner pad through a connection structure. A foot pad is arranged at the lower end of the inner pad.

[0010] Further, a support portion for supporting the back and buttocks of infants is provided on one side of the inner pad close to the first cushion.

[0011] Further, the cross-sectional shape of the support portion is arc-shaped.

[0012] Further, the head protection pad includes a main pillow portion and side guard portions arranged on both sides of the main pillow portion. The side guard portions are arranged to surround both sides of the infant's head to limit the shaking of the infant's head.

[0013] Further, both the left side guard pad and the right side guard pad include a first surface corresponding to the infant and a second surface corresponding to the second cushion assembly. A thickening portion is arranged between the first surface and the second surface.

[0014] Further, pearl holes are arranged on the first surface.

[0015] Further, the first cushion includes a seat cushion and a back cushion fixedly connected to the seat cushion. Wings are integrally arranged on both left and right sides of the seat cushion. The upper ends of the wings are detachably connected to the back cushion through a connection structure.

[0016] Further, a clamping notch for a clamping member to pass through is formed in the seat cushion.

[0017] Further, a headrest is arranged at the top end of the base cushion, and symmetric head side support portions are fixedly arranged on both sides of the headrest.

[0018] Further, the connection structure is selected from one or more of a combined mother and son buckle, a button, a lace, a magic tape, and a zipper.

A foot pad is arranged at the lower end of the inner cushion. The base cushion, the first cushion, and the second cushion assembly can be stacked and used in combination, so as to facilitate adjusting the overall thickness of the cushion. It is easy to understand that as children grow, more sitting space is required, and at this time, the thickness of the safety seat cushion is required to gradually become thinner. The following will be described in combination with the children's growth stages. When a newly born baby is sitting, the first cushion and the second cushion assembly can both be installed on the base cushion. At this time, the safety seat has strong wrapping performance and can fully surround the baby inside the inner cushion, bringing better wrapping and care feelings. When the baby grows up, the left side guard pad and the right side guard pad can be detached from the inner cushion, thereby increasing the sitting space on the left and right sides of the baby. As the baby grows further, the head protection pad can be detached from the inner cushion, thereby increasing the head movement space. When the baby grows to a state where it can sit upright, the inner cushion that supports the back and buttocks of the baby can be removed to further increase the baby's sitting space. As the baby grows further, when the sitting feeling is crowded, the first cushion can be removed from the base cushion. In summary, according to ergonomics, the present application is provided with a base cushion, a first cushion, and a second cushion assembly, so as to realize the adjustment of the overall thickness of the safety seat cushion, and further meet the sitting needs of children in different stages and of different body shapes, that is, it can be adjusted across groups and is applicable across groups, making the product have a longer service life, more economical and practical, and the safety seat cushion can be adjusted to a state that fits the child's current body shape more, which is beneficial to improving the comfort and safety of children when sitting.
