Description

Technical Field

[0001] This utility model relates to child safety seats, specifically to the inner lining of child safety seats. Background Technology

[0002] Child safety seats are essential tools for ensuring the safety of occupants (infants and children) while traveling in vehicles. A child safety seat is assembled from a rigid frame, a soft inner lining, and a cover layer. In addition, some child safety seats also include an infant seat cushion to provide more comfortable support; these infant seat cushions are also assembled from a soft inner lining and fabric. Whether it's a child safety seat or an infant seat, the soft inner lining is a crucial component that provides cushioning, support, and comfort, and is directly related to the occupant's comfort.

[0003] In existing technologies, the hardness of the seating surface of soft linings is uniform, and the support provided to the occupant by different parts of the lining is also uniform. However, during actual riding, the pressure exerted by the occupant's body on different parts of the lining varies, and the required support force for each part of the body also differs. For example, when an infant is placed in a semi-reclined position on a child car seat or child car seat cushion, the pressure on the lining by their buttocks, back, and legs is different, and the required support force for each part also varies. When traditional linings use uniform support with lower hardness, localized sagging is likely to occur; when traditional linings use uniform support with higher hardness, localized insufficient softness is likely to occur. Utility Model Content

[0004] To address the above technical problems, this utility model provides a lining pad with zoned hardness, which can provide different levels of support for the back, buttocks, and legs of infants and young children. The main technical solution adopted is as follows:

[0005] A child safety seat partitioned support inner liner includes an inner liner body, the key feature of which is that the inner liner body includes a back support part, a hip support part, and a thigh support part;

[0006] The hip support is located between the back support and the thigh support;

[0007] The back support is located above the hip support, and the hip support is located above the thigh support.

[0008] The stiffness of the thigh support is less than that of the back support.

[0009] The stiffness of the back support is less than that of the hip support.

[0010] When infants and toddlers are riding, their buttocks exert the greatest pressure on the lining, so the firmest area is provided for their support; their backs exert the next greatest pressure, so the moderately firm area is provided for their support; and their legs exert the least pressure on the lining, so the softest area is provided for their support.

[0011] Of course, there are no clear boundaries between the waist, hips and groin of infants and young children, and these areas will increase and change as the infants and young children develop; therefore, the back support area, hip support area and thigh support area are also relative regional divisions, as long as they roughly correspond to the back, hip and leg areas of most infants and young children in a certain age group. Attached Figure Description

[0012] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0013] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0014] like Figure 1 As shown, a child safety seat partition support inner liner is used for mounting on a child safety seat or an infant seat cushion on a child safety seat; it includes an inner liner body 1, which includes a seat back surface and a passenger seating surface. The seat back surface is used to abut against the main structure of the child safety seat, and the passenger seating surface is used to abut against the occupant (infant); the passenger seating surface is located in front of the seat back surface, and the passenger seating surface is an arc-shaped surface with its concave side facing forward.

[0015] Generally, in order to match the structure of a child safety seat, the seat backing surface includes a backrest backing surface and a seat cushion backing surface. The backrest backing surface is used to abut against the back of the child safety seat, and the seat cushion backing surface is used to abut against the seat cushion of the child safety seat.

[0016] The thickness of the inner liner body 1 increases from top to bottom and then decreases. The purpose of the greater thickness in the middle of the inner liner body 1 is to adapt to the corner of the backrest-seat cushion of the child safety seat.

[0017] In order to provide different support for different parts of the infant's body, the inner lining body 1 includes a back support part 1a, a hip support part 1b, and a thigh support part 1c.

[0018] The hip support 1b is located between the back support 1a and the thigh support 1c;

[0019] The back support 1a is located above the hip support 1b, and the hip support 1b is located above the thigh support 1c.

[0020] Based on the different support requirements of different parts of an infant's body, the hardness of the inner lining body 1 is set in the following manner:

[0021] The hardness of the thigh support 1c is less than that of the back support 1a.

[0022] The rigidity of the back support 1a is less than that of the hip support 1b.

[0023] To facilitate the differentiation of different hardnesses in different areas of the inner lining body 1, the material of the inner lining body 1 is selected as air fiber / air yarn. In terms of manufacturing process, adjusting the overall hardness of the air fiber / air yarn is a mature technology. For example, the air fiber filling density of the thigh support part 1c is less than that of the back support part 1a; the air fiber filling density of the back support part 1a is less than that of the hip support part 1b. Therefore, the back support part 1a, hip support part 1b, and thigh support part 1c can be integrally molded.

[0024] Of course, other materials and processes (such as polyurethane layered foaming technology, combined with appropriate cutting) can also be used to achieve different hardness in different areas of the inner lining body 1.

[0025] The hardness mentioned above refers to compressive hardness or indentation hardness.

[0026] In order to provide necessary heat dissipation and protection for the crotch area of ​​infants and young children, a crotch notch 1d is provided in the thigh support part 1c. The crotch notch 1d is located in the lower part of the thigh support part 1c and penetrates the inner lining body 1 along the thickness direction.

[0027] Beneficial effects: The child safety seat sectional support liner of this utility model can provide sectional support for different parts of the infant's body, ensuring the stability of the infant's riding posture, improving the infant's riding comfort, and solving the technical problem of the contradiction between support hardness and softness in traditional liners.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of the present utility model. Those skilled in the art, under the guidance of the present utility model, can make various similar representations without departing from the spirit and claims of the present utility model, and such modifications all fall within the protection scope of the present utility model.
