[0135] Please now refer to Figure 1A, which is a perspective view of an infant car seat 100 with a canopy 110. A child restraint system (e.g., infant car seat 100) may include a seat body 10A and a canopy assembly 10B. The seat body 10A may include a seat housing base 130. The canopy assembly 10B may be positioned over and attached to the seat body 10A. The canopy assembly 10B includes a canopy 110 (or rear panel). Optionally, the infant car seat 100 may also include a handle 10C, which may be attached to (e.g., pivotally connected to) the seat body 10A to allow a caregiver to lift the infant car seat 100 via the handle 10C. In the illustrated embodiment, the canopy 110 provides sunshade and protection for the occupant and is connected to the seat housing (or seat housing base 130) at an opposing lateral pivot point 110a (see Figure 1G) to allow for rotational adjustment. It should be understood that the opposing lateral pivot points 110a refer to the pivot points or pivot axes formed by connecting the two opposing ends of the canopy 110 in the lateral direction to the two sides of the seat housing base 130 in the lateral direction. These pivot points can be formed by the canopy 110 being directly connected to the seat housing base 130, or by the canopy 110 being indirectly connected to the seat housing base 130 (as shown in the illustrated embodiment). At least a portion of the canopy 110 can pivot about the opposing lateral pivot points to unfold or fold the canopy 110.

[0136] As shown in Figures 1B and 1C, at least a portion of the canopy 110 is made of a high-strength synthetic material (such as a reinforced thermoplastic polymer or a fiber-reinforced composite) to provide greater impact resistance and structural stiffness while minimizing weight.

[0137] As used herein, "high-strength synthetic materials" refers to a synthetic fiber or composite material, such as a high compressive / tensile synthetic fiber material characterized by a tensile strength exceeding approximately [X] MPa and a tensile strength-to-weight ratio greater than that of commonly used materials such as ABS (Acrylonitrile-Butadiene-Styrene Copolymer) plastics or aluminum. Examples of such materials include, but are not limited to, ultra-high molecular weight polyethylene (UHMWPE) fibers, para-aramid fibers, liquid crystal polymer fibers, or other engineering fibers suitable for lightweight reinforcement applications.

[0138] Compared to ordinary textiles, high-performance synthetic fibers, namely high compressive / tensile strength synthetic fiber materials (such as... and It possesses superior mechanical properties, including higher tensile strength, impact resistance, and flame retardancy in some cases. Incorporating this material into specific components of child or pet transport equipment can significantly increase its protective capabilities, improving the safety and well-being of infants, children, and animals. Furthermore, replacing some heavier structural materials (such as metals or high-density plastics) with these lightweight yet strong fibers can reduce the overall weight of the product without compromising structural integrity or safety.

[0139] The high-strength synthetic materials (e.g., high compressive / tensile synthetic fiber materials) disclosed herein can be used in various car seat products, such as infant car seat 100, toddler car seat, rotatable child car seat, or multi-configuration child car seat. Among these, multi-configuration child car seats include, for example, child car seats equipped with seatbelt trainers, which can be used alone or in conjunction with other components of the child car seat, as will be explained later.

[0140] In one embodiment, as shown in Figures 1A-1C, the canopy 110 may include multiple attachments connected to each other, and the attachments of the canopy 110 may be sheet-like structures. A high-compression / tensile-strength synthetic fiber material may be formed into a fabric and used in different areas of the canopy 110 (as shown in the gray areas in Figures 1B-1C). The canopy assembly 10B may also include several support rib structures 190 for supporting the attachments of the canopy 110. Both the support rib structures 190 and the high-compression / tensile-strength synthetic fiber material can provide stronger protection for children in the event of a car accident or impact.

[0141] Specifically, the canopy 110 may include a main attachment 111 that can be mounted on top of the seat housing base 130 and side attachments 112 that can be disposed around the outer periphery of the seat housing base 130, with the side attachments 112 connected to the lower edge of the main attachment 111. Multiple support rib structures 190 may be provided, supporting the main attachments 111 so that the main attachments 111 are generally arched when the canopy 110 is deployed. The support rib structures 190 may be supported on the inner side of the canopy 110 (e.g., the main attachment 111) or enclosed within the canopy 110 (e.g., the main attachment 111). The multiple support rib structures 190 can divide the canopy 110 into multiple main attachments 111, which are arranged generally in a front-to-back direction, with each main attachment 111 having its two ends connected to the side attachments 112.

[0142] The attachments to the canopy 110 (main attachment 111 and / or side attachment 112) may also be formed of other materials, such as those that increase ventilation. In other words, the child restraint system (e.g., infant car seat 100) may include a breathable layer made of a breathable material that can increase ventilation. In this embodiment, the canopy 110 may be provided with a breathable layer. Of course, in other embodiments, breathable layers may also be provided in other areas of the child restraint system.

[0143] As shown in Figure 1B, the entire area of ​​the canopy 110, including the main attachments 111 and side attachments 112, can be formed as a single reinforcing region 101, with the area containing a high-strength synthetic material (e.g., high compressive / tensile synthetic fiber material) serving as the reinforcing region 101. Optionally, as shown in Figure 1C, a portion of the canopy 110 can be formed as the reinforcing region 101. The canopy 110 may have multiple reinforcing regions 101, which can be formed by multiple spaced-apart areas of the canopy 110 covering the seat housing base 130, for example, by multiple spaced-apart main attachments 111. Of course, in some embodiments not shown, the reinforcing region 101 of the canopy 110 may also be formed by the side attachments 112 and / or at least one (i.e., one or more) main attachments 111.

[0144] It should be noted that, unless otherwise explicitly specified and limited, the directional terms such as "front," "rear," "left," "right," "up," and "down" in this disclosure are based on the "front," "rear," "left," "right," "up," and "down" orientations of the described object (such as a child restraint system) in normal use (such as forward use). These directional terms are only used to make the description of the embodiments of this disclosure clearer and are not intended to unduly limit the scope of protection of this disclosure.

[0145] In some embodiments, the child restraint system (e.g., infant car seat 100) may have a protective layer attached to the seat body 10A. Optionally, the protective layer may be made of a high-strength synthetic material. At least a portion of the canopy 110 may be formed as or attached to the protective layer. For example, the entire canopy 110 may be formed as or attached to the protective layer; or, the protective layer may be located in a reinforcing region 101 on the canopy 110. Optionally or alternatively, a breathable layer on the canopy 110 may be formed as the protective layer. The protective layer may serve as a protective structure of the child restraint system in this embodiment or as part of such a protective structure.

[0146] Figures 2A-2C illustrate an infant car seat 100 according to some embodiments of the present disclosure. Similar to the embodiments of Figures 1A-1C, a child restraint system (e.g., infant car seat 100) may include a seat body 10A, a canopy assembly 10B, and a carry handle 10C. The canopy assembly 10B may include a canopy 110. The infant car seat 100 may include a protective layer attached to the seat body 10A.

[0147] In some embodiments, the infant car seat 100 also includes an extension. This extension extends from the canopy assembly 10B or the carry handle 10C and covers the seat body 10A to provide additional protection. In the embodiments shown in Figures 2A to 2C, the infant car seat 100 also includes a retractable sunshade 120, for example, the canopy assembly 10B may also include a retractable sunshade 120. This retractable sunshade 120 extends from the canopy 110 to provide additional protection. The extension can be the retractable sunshade 120. The extension (e.g., the retractable sunshade 120) can also be made of a high-strength synthetic material to maintain structural integrity during use and retraction.

[0148] High-strength synthetic materials are, for example, high compressive / tensile synthetic fiber materials, which may include, but are not limited to, ultra-high molecular weight polyethylene (UHMWPE) fibers, para-aramid fibers, liquid crystal polymer fibers, or other engineering fibers suitable for lightweight reinforcement applications.

[0149] Referring to Figures 2A-2C, a high-strength synthetic material, such as a high-compression / tensile synthetic fiber material, can be used for the canopy assembly 10B of an infant car seat. The canopy assembly 10B can be divided into multiple panels, including a front panel (i.e., the retractable sunshade 120) and a rear panel (i.e., the canopy 110). The front panel may include a first attachment 121 located at the front and two second attachments 122 connected to the first attachment 121. The two second attachments 122 are located on opposite sides of the first attachment 121 (e.g., the left and right sides of the first attachment 121). The high-compression / tensile synthetic fiber material can be formed as a fabric and used for the front panel (as shown in the gray areas in Figures 2A-2C). The attachments of the retractable sunshade 120 (the first attachment 121 and / or the second attachments 122) can be sheet-like structures. The high compressive / tensile strength synthetic fiber material can be used for the first attachment 121, or the second attachment 122, or both of the first attachment 121 and the second attachment 122 of the front panel (i.e., the retractable sunshade 120). In other words, the first attachment 121 and / or the second attachment 122 of the retractable sunshade 120 can be made of a high-strength synthetic material, such as a high compressive / tensile strength synthetic fiber material, or can be attached with a high-strength synthetic material, such as a high compressive / tensile strength synthetic fiber material.

[0150] The attachments (first attachment 121 and / or second attachment 122) of the retractable sunshade 120 may also be made of other materials, such as those that enhance ventilation. In other words, the retractable sunshade 120 may be provided with a breathable layer, which may be made of a material that enhances ventilation. Exemplarily, the first attachment 121 may be formed of a breathable layer; or, the second attachment 122 may be formed of a breathable layer; or, both the first attachment 121 and the second attachment 122 may be formed of a breathable layer.

[0151] In some embodiments, the panel structure (including the canopy 110 and the retractable sunshade 120) can also provide debris protection in the event of a car accident or collision.

[0152] Optionally, referring to FIG2A, the first attachment 121 of the retractable sunshade 120 is formed as the reinforcement region 101; or, referring to FIG2B, the two second attachments 122 of the retractable sunshade 120 are formed as the reinforcement region 101; or, referring to FIG2C, the first attachment 121 and the second attachment 122 of the retractable sunshade 120 are integrally formed as the reinforcement region 101.

[0153] In some embodiments, the protective layer may be made of a high-strength synthetic material, which may include a high compressive / tensile strength synthetic fiber material. At least a portion of the retractable sunshade 120 may be formed as or attached to the protective layer. The protective layer may be disposed in the reinforcing region 101 of the retractable sunshade 120 (e.g., the first attachment 121 and / or the second attachment 122), i.e., the first attachment 121 and / or the second attachment 122 may be formed as or attached to the protective layer. Optionally or alternatively, the breathable layer of the retractable sunshade 120 may be formed as the protective layer, i.e., the protective layer may include a breathable layer. The protective layer may serve as a protective structure of the child restraint system in this embodiment or as part of such a protective structure.

[0154] Figures 3A-3G are schematic structural diagrams of an infant car seat 100 according to some embodiments of the present disclosure. Similar to the embodiments in Figures 1A-2C, the infant car seat 100 includes a seat body 10A, a canopy assembly 10B, and a carry handle 10C. The infant car seat 100 may include a protective layer. The protective layer may be made of a high-strength synthetic material, such as a high compressive / tensile strength synthetic fiber material. In some embodiments, the protective layer may be attached to the seat body 10A of a child restraint system (e.g., the infant car seat 100), or at least a portion of the seat body 10A may be formed as a protective layer. The seat body 10A includes a seat housing base 130. The protective layer may serve as a protective structure of the child restraint system in this embodiment or as part of that protective structure.

[0155] Figure 3A shows the infant car seat 100 with the canopy removed, exposing the seat housing base 130. As shown, the seat housing base 130 is also made of a high-strength synthetic material, providing a lightweight yet robust structural foundation for the infant car seat 100. Figures 3C to 3G further illustrate various embodiments of the infant car seat 100, showing different configurations in which various parts of the seat body 10A, such as the front, sides, or other structural areas, can be made of a high-strength synthetic material.

[0156] As shown in Figures 3A-3G, the seat body 10A includes a seat housing base 130. The seat housing base 130 includes a front portion and two opposing side portions. The seat housing base 130 can be formed as at least a part of the housing of the seat body 10A.

[0157] Referring to 3A and 3C, optionally, the front portion (i.e., the leading edge region) of the seat housing base 130 is provided with a structural recess or cutout (or referred to as a front recess 131), configured to engage with a latch on a support surface of the base body (not shown) to secure the infant car seat 100 to the base body for use. The front recess 131 has forward-facing and downward-facing openings. The seat body 10A may also include a front connecting rod 134, at least a portion of which is located within the front recess 131, and both ends of the front connecting rod 134 are respectively connected to or integrally formed with the sidewalls of the front recess 131.

[0158] Referring to Figure 3D, optionally, a structural recess or cutout (or rear recess 132) is provided in the rear portion (i.e., the rear edge region) of the seat housing base 130, configured to engage with a latch on the support surface of the base body (not shown) to secure the infant car seat 100 to the base body for use. The rear recess 132 has rearward and downward openings. The seat body 10A also includes a rear connecting rod 135, at least a portion of which is located within the rear recess 132, and both ends of the rear connecting rod 135 are respectively connected to or integrally formed with the sidewalls of the rear recess 132.

[0159] In some embodiments, the rear recess 132 may communicate with the front recess 131 to form a channel through which the seat belt 10D extends from the rear of the seat body 10A to the front of the seat body 10A, so as to adjust the tightness of the seat belt 10D.

[0160] High-strength synthetic materials are, for example, high compressive / tensile synthetic fiber materials, which may include, but are not limited to, ultra-high molecular weight polyethylene (UHMWPE) fibers, para-aramid fibers, liquid crystal polymer fibers, or other engineering fibers suitable for lightweight reinforcement applications.

[0161] High compressive / tensile strength synthetic fiber materials can be used in the shell area of ​​the infant car seat 100 (e.g., seat shell base 130) to improve the safety and reduce the weight of the infant car seat 100. This material can be formed as a shell (e.g., seat shell base 130) or attached to a shell area (e.g., seat shell base 130). This material can also be located in the end areas of the infant car seat 100 (e.g., the front and rear of the seat body 10A) to enhance strength during impact. The end areas may include an ISOFIX structure 150 or a frame structure.

[0162] The area provided with a high-strength synthetic material (e.g., high compressive / tensile synthetic fiber material) is designated as the reinforcement region 101. Specifically, as shown in Figures 3A and 3B, in one embodiment, the seat housing base 130 can be integrally formed as the reinforcement region 101, meaning the entire seat housing base 130 can be formed of a high-strength synthetic material or its surface can be attached with a high-strength synthetic material. As shown in Figure 3C, in one embodiment, the front portion of the seat body 10A (e.g., the front portion of the seat housing base 130 and the wall of the front recess 131) can be provided or formed as the reinforcement region 101. As shown in Figures 3D and 3E, in some embodiments, the wall of the front recess 131 can be provided or formed as the reinforcement region 101. Optionally, the wall of the rear recess 132 can be provided or formed as the reinforcement region 101; alternatively, the wall of the entire channel can be provided or formed as the reinforcement region 101. As shown in Figures 3F and 3F, in one embodiment, the front connecting rod 134 can be provided or formed as the reinforcement region 101. Of course, in some embodiments not shown, the rear connecting rod 135 may be provided or formed as the reinforcing region 101.

[0163] The protective layer may be disposed in the reinforced region 101, which may be formed as or attached to at least a portion of the housing of the seat body 10A (i.e., the seat housing, such as the seat housing base 130).

[0164] Figure 4 shows the connecting element 140 for the handle 10C. The handle 10C has connecting elements 140 at both ends, allowing it to be pivotally connected to the seat housing base 130. In other words, the connecting element 140 forms a pivoting area for the handle 10C. The connecting element 140 can be made of a high-strength composite material, providing robust load-bearing capacity and reducing weight during lifting, handling, or vehicle installation.

[0165] High-strength synthetic materials can be, for example, high compressive / tensile synthetic fiber materials, which may include, but are not limited to, ultra-high molecular weight polyethylene (UHMWPE) fibers, para-aramid fibers, liquid crystal polymer fibers, or other engineering fibers suitable for lightweight reinforcement applications.

[0166] High-strength composite materials can be applied to the pivot area of ​​the handle 10C. In other words, the connecting element 140 can be formed as a reinforcing region 101. This increases strength and extends service life. Furthermore, the pivot area of ​​the handle 10C (i.e., the connecting element 140) can also be used as a side-impact protection device in the event of a car accident to prevent damage.

[0167] In the embodiment shown in Figure 4, the protective layer can be made of a high-strength synthetic material, such as a high compressive / tensile strength synthetic fiber material. The connecting element 140 can be formed as or attached to the protective layer; in other words, the connecting element 140 can serve as the protective layer.

[0168] Figures 5A and 5B show front views of a child car seat 200, wherein the front impact shield 210 is made of a high-strength synthetic material to improve frontal impact resistance. The child car seat 200 may include a seat body 20A, a base 20B, and the front impact shield 210 disposed on the front side of the seat body 20A. The seat body 20A is supported on the base 20B. The child car seat 200 may serve as an example of a child restraint system or as part of a child restraint system.

[0169] The child car seat 200 may include a protective layer, and at least a portion of the front shield 210 may be formed as or attached to the protective layer, which may be made of a high-strength synthetic material. The protective layer may serve as a protective structure of the child restraint system in this embodiment or as part of that protective structure.

[0170] High-strength synthetic materials are, for example, high compressive / tensile synthetic fiber materials, which may include, but are not limited to, ultra-high molecular weight polyethylene (UHMWPE) fibers, para-aramid fibers, liquid crystal polymer fibers, or other engineering fibers suitable for lightweight reinforcement applications.

[0171] High-strength synthetic materials can be applied to the front shield 210 located at the front of the child car seat 200. The front shield 210 can be connected to the seat body 10A of the child car seat 200 via a soft or hard latch system to prevent the child from rolling out upon impact to the back. The front shield 210 may include a receiving area 211 for accommodating the child's arms to provide comfort. High compressive / tensile strength synthetic fiber materials can be used to form the front shield 210 or attached to its outer surface to enhance its strength. This high compressive / tensile strength synthetic fiber material may also not cover the area accommodating the arms (i.e., the receiving area 211 may not be covered with high-strength synthetic material), which can also provide better comfort for the child.

[0172] The area on the child car seat 200 that is provided with a high-strength synthetic material, such as a high-compression / tensile synthetic fiber material, is designated as the reinforcement area 201. As shown in FIG5A, in one embodiment, the portion of the front shield 210 other than the receiving area 211 can be made of or have a high-strength synthetic material attached, so that all portions of the front shield 210 other than the receiving area 211 can be formed as reinforcement areas 201. As shown in FIG5B, in another embodiment, the entire front shield 210 can be made of or have a high-strength synthetic material attached, so that the entire front shield 210 can be formed as reinforcement areas 201. All reinforcement areas 201 of the front shield 210 can be formed as protective layers.

[0173] The front impact shield 210 can replace a traditional seatbelt by providing wider overall coverage of the child's torso. It can also be used in conjunction with a traditional seatbelt. The design of the front impact shield 210 distributes restraint forces more evenly over a larger surface area, improving comfort and safety. The front impact shield 210 is made of high-strength synthetic materials to ensure durability and maintain structural integrity under dynamic load conditions. The front impact shield 210 can be installed alone or in combination with an existing seatbelt, allowing for flexible restraint configurations.

[0174] Figures 6 to 9 show schematic diagrams of a child car seat 200 according to an embodiment of the present disclosure. The child car seat 200 can be positioned in both a forward-facing and a rearward-facing position; that is, the child car seat 200 has at least a forward-facing mode and a rearward-facing mode. The child car seat 200 includes a base 20B and a seat body 20A. Optionally, the seat body 20A is rotatably disposed on the base 20B and can be positioned in at least a forward-facing and a rearward-facing position. The child car seat 200 can serve as an example of a child restraint system or as part of a child restraint system.

[0175] As shown in Figures 6-9, the seat body 20A includes a seat portion 2A, a backrest 2B, and a headrest 2C. The backrest 2B is connected to the rear end of the seat portion 2A and, together with the seat portion 2A, defines the seating space 2D of the seat body 20A. The headrest 2C may be disposed on the upper part of the backrest 2B and located on the side of the backrest 2B facing the seat portion 2A. Optionally, the headrest 2C may be movably disposed on the backrest 2B to facilitate adjustment of the height of the headrest 2C on the backrest 2B. When the child car seat 200 is configured in a forward-facing mode on a vehicle seat (not shown in this embodiment), the seating space 2D is located on the side of the backrest 2B away from the backrest of the vehicle seat; when the child car seat 200 is configured in a rear-facing mode on a vehicle seat, the seating space 2D is located between the backrest 2B and the backrest of the vehicle seat.

[0176] The seat 2A can be detachably connected to the backrest 2B. The seat 2A can be, for example, a booster seat and can be installed as a separate unit on the vehicle seat, in which case it can be used by older children.

[0177] In Figures 6 to 9, one or more seatbelt path guides (i.e., seatbelt guides 220) are installed or provided on the child car seat (or child safety seat). Seatbelt path guides with side openings (such as seatbelt guide 224) and seatbelt paths without side openings (such as seatbelt guide 222) can both be considered as a type of seatbelt guide 220. The seat body 20A has at least one channel for the seatbelt to pass through. One or more seatbelt guides 220 are respectively disposed within at least one channel.

[0178] These seat belt guides 220 can be made of high-strength synthetic materials, or have attached high-strength synthetic materials, i.e., the seat belt guides 220 are formed as or provided with reinforced areas 201, which can be used for various vehicle seat (or car seat) seat belts and ensure durability under repeated loading and environmental exposure as well as weight reduction.

[0179] High-strength synthetic materials are, for example, high compressive / tensile synthetic fiber materials, which may include, but are not limited to, ultra-high molecular weight polyethylene (UHMWPE) fibers, para-aramid fibers, liquid crystal polymer fibers, or other engineering fibers suitable for lightweight reinforcement applications.

[0180] High-strength synthetic materials can be used in the seat belt guide 220 of the child car seat 200 (including the seat belt path of the child car seat 200). For example, the seat belt path can be located on the seat 2A or backrest 2B for the child car seat 200's seat belt (or referred to as seat belt 20D), LATCH seat belt (not shown in this embodiment), or vehicle seat belt (not shown in this embodiment) to pass through. Optionally, the seat belt guide 220 can be located in the shoulder, torso, hip, or leg areas.

[0181] The seatbelt guide 220 may be made of a high-compression / tensile synthetic fiber material, or a high-compression / tensile synthetic fiber material may be attached to the outer surface of the seatbelt guide 220 (highlighted in red in Figure 6-9). This material can improve integrity in the event of an accident or extend the service life of the seatbelt path.

[0182] In other words, the child car seat 200 can be equipped with a protective structure, which may include, for example, a protective layer made of a high-strength synthetic material (e.g., a high-compression / tensile synthetic fiber material). The protective layer may be formed as or attached to the seat belt guide 220.

[0183] Referring to Figures 6 and 9, the seat belt guide may include a shoulder seat belt guide 221 (i.e., a booster seat shoulder seat belt guide). The shoulder seat belt guide 221 may be disposed on the headrest 2C for passage of the vehicle seat belt (not shown). The shoulder seat belt guide 221 may be located in the shoulder area of ​​the seat body 20A, approximately corresponding to the child's shoulder.

[0184] In some embodiments, the seat belt 20D may be a five-point harness. A shoulder belt guide may be provided through which the shoulder strap of the seat belt 20D passes. By reinforcing the shoulder belt guide with high-strength synthetic materials (e.g., high compressive / tensile synthetic fiber materials), the integrity and strength of the shoulder belt guide can be improved, ensuring its durability.

[0185] As shown in Figures 6-9, optionally or alternatively, the seatbelt guide 220 includes a forward seatbelt guide 222 (i.e., a forward seatbelt path), a rearward seatbelt guide 223 (i.e., a rearward seatbelt path), and a legbelt guide 224 (i.e., a booster seat legbelt guide). The forward seatbelt guide 222 allows the vehicle seatbelt (not shown) or a LATCH seatbelt (not shown) to pass through when the child car seat 200 is in forward-facing mode to secure the child car seat 200 to the vehicle seat. The forward seatbelt guide 222 may be located on the backrest 2B. The forward seatbelt guide 222 may be located in the torso area of ​​the seat body 20A that substantially corresponds to the child's torso. The rearward seatbelt guide 223 allows the vehicle seatbelt or a LATCH seatbelt to pass through when the child car seat is in rear-facing mode to secure the child car seat to the vehicle seat. Optionally, the rear-facing seat belt guide 223 is provided in the seat portion 2A, specifically, in the end of the seat portion 2A away from the backrest (i.e., the front end of the seat portion 2A).

[0186] The leg belt guide 224 can be located in the leg area of ​​the seat body 20A that roughly corresponds to the child's thigh. Optionally, the leg belt guide 224 is disposed in the seat 2A (i.e., booster seat) and located between the backrest 2B and the front end of the seat 2A. When the child car seat 200 is in use, or when the seat 2A (i.e., booster seat) is used alone on the vehicle seat, the vehicle safety lap belt can pass through the leg belt guide 224 and engage with the vehicle seat via the vehicle safety belt connector and a connector on the vehicle seat (not shown in this embodiment), thereby using the vehicle safety belt to jointly restrain the booster seat and the child sitting in the booster seat on the vehicle seat. At this time, the child's thigh is restrained between the vehicle safety belt lap belt and the seat 2A. The leg belt guide 224 has a side opening through which the belly strap of the vehicle seat belt can enter the leg belt guide 224 and wrap around the child's thigh, so that the child and seat 2A can be restrained on the vehicle seat by the vehicle seat belt.

[0187] High-strength synthetic materials can be, for example, high compressive / tensile synthetic fiber materials, which may include, but are not limited to, ultra-high molecular weight polyethylene (UHMWPE) fibers, para-aramid fibers, liquid crystal polymer fibers, or other engineering fibers suitable for lightweight reinforcement applications.

[0188] High-strength synthetic materials can also be used in the area of ​​the car seat adjacent to the seatbelt path 220 (highlighted in yellow in Figures 7 and 8) to form a reinforcement (or extension guide 202). This extension guide 202 can be made of a high-compressive / tensile synthetic fiber material, or a high-compressive / tensile synthetic fiber material can be attached to the outer surface of the seatbelt path. In other words, the extension guide 202 can be formed as or have a protective layer attached. Exemplarily, the extension guide 202 can be provided in the adjacent area of ​​the forward seatbelt guide 222. By enhancing the strength of the adjacent area of ​​the forward seatbelt guide 222, the structural strength of the adjacent area of ​​the forward seatbelt guide 222 can be improved, preventing cracking or breakage in the area where the extension guide 202 is located, thus preventing the forward seatbelt guide 222 from detaching. This improves the structural integrity of the forward seatbelt guide 222 in the event of an accident (e.g., a collision) and / or extends the service life of the forward seatbelt guide 222.

[0189] Figures 10A and 10B show structural schematic diagrams of a child car seat 200 according to an embodiment of the present disclosure.

[0190] As shown in Figures 10A and 10B, similar to the child car seat 200 shown in Figures 6 to 9, the child car seat 200 of this embodiment may include a base 20B and a seat body 20A disposed on the base 20B. The seat body 20A may include a seat portion 2A, a backrest 2B, and a headrest portion 2C. The seat portion 2A may be a booster seat, and the seat portion 2A may be detachably connected to the backrest 2B. The child car seat 200 may serve as an example of a child restraint system or as part of a child restraint system.

[0191] The child car seat 200 includes at least one support frame 230 located at the rear of the seat (i.e., seat body 20A). When there are multiple support frames 230, they are spaced apart from each other to prevent breakage or enhance structural integrity in a collision or crash. The at least one support frame 230 may also be made of a high-strength synthetic material, or a high-strength synthetic material may be attached to the surface of the at least one support frame 230 to enhance the load-bearing capacity of the child car seat 200, improve energy distribution in a rear-end collision, and reduce weight.

[0192] [Corrected according to Rule 91, 05.06.2026] The chair back (i.e., the backrest 2B) may include a pair of support members (i.e., support frames 230). That is, there may be two support frames 230. Each support member may be tubular, strip-shaped, or other suitable in shape. Each support member provides rigidity to the backrest 2B. The two support frames 230 extend generally parallel to each other. Each support frame 230 is located on the rear side of the backrest 2B and extends vertically along the rear side of the backrest 2B. Each support frame 230 may extend from the upper part of the backrest 2B toward the base 20B and to the lower part of the backrest 2B.

[0193] High-strength synthetic materials are, for example, high compressive / tensile strength synthetic fiber materials. These may include, but are not limited to, ultra-high molecular weight polyethylene (UHMWPE) fibers, para-aramid fibers, liquid crystal polymer fibers, or other engineering fibers suitable for lightweight reinforcement applications. High compressive / tensile strength synthetic fiber materials can be used in the shell of a child car seat 200 (e.g., the shell of the backrest 2B) to improve the safety of the car seat 200 and reduce its weight. This material can be formed into the shell of the backrest 2B or attached to the shell area of ​​the backrest 2B. For example, high compressive / tensile strength synthetic fiber materials can be disposed on a pair of supports to prevent breakage or enhance their integrity in a collision or crash.

[0194] Figures 11 to 13 illustrate a seatbelt trainer 300 that can be used as part of a modular child car seat system (or child restraint system). The seatbelt trainer 300 includes a trainer seat 320. The child car seat 200 in this embodiment can be, for example, any of the child car seats 200 shown in the embodiments of Figures 6-10B, with the seat 2A (i.e., booster seat) detachably connected to the backrest 2B. Referring to Figure 11, the seatbelt trainer 300 is detachably mounted on the child car seat 200. The seatbelt trainer 300 can be used independently in the vehicle seat.

[0195] As shown in Figures 11-13, the seatbelt trainer 300 can be placed in the seat 2A of a child car seat 200. The trainer seat 320 is provided with through holes 321 extending through its upper and lower opposite sides, through which the seatbelt can pass. The trainer seat 320 can have multiple through holes 321, such as two through holes 321, to adjust the position of the child car seat belt after it emerges from the through holes 321.

[0196] Referring again to Figures 11-13, the seatbelt trainer 300 may further include a seatbelt guide 310 (or seatbelt guide) to maintain the correct positioning of the vehicle seatbelt (not shown in this embodiment). The seatbelt guide 310 may be made of a high-strength synthetic material, or its surface may be coated with a high-strength synthetic material. The seatbelt guide 310 is located on opposite sides of the hip area.

[0197] Specifically, the seat belt guide 310 is generally U-shaped and is positioned below the trainer seat 320. Both ends of the seat belt guide 310 extend from opposite sides of the trainer seat 320 to the top of the trainer seat 320 to engage with the vehicle seat belt. Recesses 322 are provided on opposite sides of the trainer seat 320, and both ends of the seat belt guide 310 extend from these recesses to the top of the trainer seat 320. The seat belt guide 310 has guide channels 311 with forward-facing lateral openings for the vehicle seat belt to enter and be contained within, thereby guiding and positioning the vehicle seat belt. Two guide channels 311 are provided, each located at one of the two ends of the seat belt guide 310 extending from the two recesses 322 to the top of the trainer seat 320. By setting two guide channels 311, the seat belt guide 310 can effectively limit the path of the vehicle seat belt after it passes through the guide channels 311.

[0198] High-strength synthetic materials can be, for example, high-compression / tensile synthetic fiber materials, which may include, but are not limited to, ultra-high molecular weight polyethylene (UHMWPE) fibers, para-aramid fibers, liquid crystal polymer fibers, or other engineering fibers suitable for lightweight reinforcement applications. High-compression / tensile synthetic fiber materials can be used in the seatbelt trainer 300. The seatbelt trainer 300 may be made of high-compression / tensile synthetic fiber materials, or the high-compression / tensile synthetic fiber material may be attached to the outer surface of the seatbelt trainer 300 (e.g., the red highlighted areas in Figures 12 and 13). This material can improve integrity in an accident or extend the service life of the seatbelt trainer 300.

[0199] Figures 14 to 17 illustrate the structure of an infant car seat 100A according to an embodiment of the present disclosure. The infant car seat 100A may include a seat body 10A, a base 10b, and a handle 10C. The base 10b can be placed on a vehicle seat (not shown in this embodiment), the seat body 10A is disposed on the base 10b, and the handle 10C is connected to the base 10b for easy carrying of the infant car seat 100A. The infant car seat 100A may serve as an example of a child restraint system or as part of a child restraint system.

[0200] As shown in Figures 14-17, the seat body 10A is provided with a seat belt guide 180. The seat body 10A has a foot area 190a for a child to place their feet, and abutment portions 191 are formed on the left and right sides of the foot area 190a. The abutment portions 191 are located in the area where the front edge of the seat body 10A transitions to the upper side edge. The abutment portions 191 are generally triangular. When the infant car seat 100A is installed in a vehicle seat (not shown in this embodiment), the abutment portions 191 can rest against the back of the vehicle seat.

[0201] The seat belt guide 180 and foot area 190a may be made of high-strength synthetic material, or the outer surfaces of the seat belt guide 180 and foot area 190a may be attached with high-strength synthetic material to improve structural support and abrasion resistance and reduce weight.

[0202] Optionally, the high-strength synthetic material may be, for example, a high-compression / tensile synthetic fiber material, which may include, but is not limited to, ultra-high molecular weight polyethylene (UHMWPE) fibers, para-aramid fibers, liquid crystal polymer fibers, or other engineering fibers suitable for lightweight reinforcement applications. For example, the high-compression / tensile synthetic fiber material may be used in the seat belt guide 180 of an infant safety seat. This material can improve integrity in the event of an accident or extend the service life of the seat belt path (i.e., the seat belt guide 180). The seat belt guide 180 may be made of the high-compression / tensile synthetic fiber material, or the high-compression / tensile synthetic fiber material may be attached to the outer surface of the seat belt guide 180.

[0203] In some embodiments, the infant car seat 100A includes a protective layer, which may be made of a high-strength synthetic material, specifically, for example, a high-compression / tensile-strength synthetic fiber material. The seatbelt guide 180 may be made of the protective layer or have a protective layer attached to its outer surface. The protective layer may serve as a protective structure of the child restraint system in this embodiment or be part of that protective structure. As shown in Figures 14-17, the seatbelt guide 180 may include a first seatbelt guide 181 and a second seatbelt guide 182. First seatbelt guides 181 may be provided on both the left and right sides of the seat body 10A. A vehicle seatbelt (not shown) may pass through the first seatbelt guides 181 on both sides and be secured to the vehicle seat, thereby securing the infant car seat 100A to the vehicle seat.

[0204] [Corrected according to Rule 91, 05.06.2026] Specifically, channels 133 for the vehicle seat belt to pass through are respectively provided on the left and right sides of the seat body 10A. The channels 133 extend through the inner and outer sides of the seat body 10A in a generally left-right direction. The channels 133 are generally located in the middle of the seat body 10A in the front-rear direction. For example, the channel 133 can be a U-shaped groove with the opening facing backward. A first seat belt guide 181 is provided at the channel 133 and has a slot that matches the shape of the channel 133. At least a portion of the first seat belt guide 181 is attached to the outer side of the seat body 10A. For example, a portion of the first seat belt guide 181 is attached to the outer side of the seat body 10A, and another portion is inserted into the channel 133 and extends towards the inner side of the seat body 10A; or, for another example, the first seat belt guide 181 is entirely attached to the outer side of the seat body 10A.

[0205] The second seat belt guide 182 is disposed at the rear of the seat body 10A, and the second seat belt guide 182 is located approximately at the center of the seat body 10A in the left-right direction.

[0206] At least one of the first seatbelt guide 181 and the second seatbelt guide 182 may be made of or constructed from a high-strength synthetic material. That is, at least one of the first seatbelt guide 181 and the second seatbelt guide 182 is made of a protective layer or has a protective layer attached to its outer surface. Referring to Figures 14 and 15, the first seatbelt guide 181, located on the left and right sides of the seat body 10A, is made of or constructed from a high-strength synthetic material. As shown in Figures 16 and 17, the second seatbelt guide 182 is made of or constructed from a high-strength synthetic material.

[0207] Alternatively, high compressive / tensile strength synthetic fiber materials can also be used for the outer shell, such as the shell of the seat body 10A (or seat housing). This material can improve overall integrity in the event of an accident, or extend the service life of the seatbelt path (i.e., the seatbelt guide 180) and reduce weight. Specifically, this material can be arranged in the foot area 190a of the infant car seat, for example, the abutment portion 191. That is, the abutment portion 191 of the seat housing can be made of a high-strength synthetic material, or its surface can be covered with a high-strength synthetic material. In other words, the shell of the seat body 10A can be made of a protective layer.

[0208] The seat body 10A is also provided with a reinforcement (or extension guide 102) that surrounds the seat belt guide 180 to maintain integrity in the event of a crash. The extension guide 102 may be provided on the inner side of the seat body 10A, and a portion of the extension guide 102 is provided around the channel 133 to enhance the strength in the vicinity of the channel 133.

[0209] Figures 18A to 18H illustrate various embodiments of the infant carrier 400. The carrier (such as the infant carrier 400) can be, for example, an infant sling. The infant carrier 400 is designed to be worn by a caregiver and to provide safe and ergonomic support for the infant. The infant carrier 400 includes a main body 40A, a support strap (or carrying system 40B), and a securing system 40C.

[0210] As shown in Figures 18A-18H, the main body 40A may include a torso support 430 for supporting the infant's torso. The torso support 430 may have an ergonomic shape to evenly distribute the infant's weight to the wearer's torso.

[0211] The main body 40A also includes a head and neck support 410 and a thigh support 450. The head and neck support 410 is located above the trunk support 430 and is adjustable to provide different levels of support according to the infant's size and developmental stage. The thigh support 450 is connected to and located on the lower opposite side of the trunk support 430.

[0212] In some embodiments, the infant carrier 400 includes different functional areas, including a head and neck support area (i.e., head and neck support 410), a harness support area (i.e., harness support 420), a torso support area (i.e., torso support 430), and a thigh support area (i.e., thigh support 450). These areas may be made of different materials depending on the needs of each area. For example, the head and neck support 410 may be made of a softer cushioning material to protect sensitive anatomical areas, while the torso support 430 and harness support 420 may be made of high-strength synthetic materials to provide structural stability and load-bearing capacity. The infant carrier 400 may also include a hip support 440. The harness support 420, torso support 430, and hip support 440 may be collectively formed into a body 40A. In other words, the body 40A may include the harness support 420, torso support 430, and hip support 440. Optionally, the shoulder strap support 420, the torso support 430, and the hip support 440 are formed as a single unit.

[0213] The baby carrier system 40B may include length-adjustable shoulder straps 41, size-adjustable waist belt 42, and side support straps (not shown). The shoulder straps 41 are worn over the wearer's shoulders. The waist belt 42 secures the baby carrier to the wearer's waist to distribute weight. The side support straps extend from the torso support to either the shoulder straps 41 or the waist belt 42. The side support straps can be used to prevent lateral movement of the baby during use.

[0214] [Corrected according to Rule 91 05.06.2026] The restraint system 40C is used to securely support the infant within the torso support 430. The restraint system 40C may include adjustable fasteners 44 to accommodate different caregiver body types. The sizes of the shoulder straps 41 and waist belt 42 can be adjusted by the fasteners 44, so that caregivers of different body types can comfortably wear the infant carrier 400.

[0215] The infant carrier 400 is made at least in part of high-strength synthetic materials to ensure durability while maintaining a lightweight structure suitable for extended use. Reinforced shell components (i.e., the main body 40A) and ergonomic design features contribute to improved overall comfort and occupant safety, while maintaining the rigidity required for structural integrity.

[0216] The high-strength synthetic materials include, for example, high-compression / tensile synthetic fiber materials, which may include, but are not limited to, ultra-high molecular weight polyethylene (UHMWPE) fibers, para-aramid fibers, liquid crystal polymer fibers, or other engineering fibers suitable for lightweight reinforcement applications. These high-compression / tensile synthetic fiber materials can be used in infant carriers to enhance overall integrity, support, or breathability. They can also be further sewn with fabrics to increase flexibility. As shown in Figures 18A to 18D, the high-compression / tensile synthetic fiber material can be used in different areas of the infant carrier 400, such as the head and neck support 410, the torso support 430, or the hip support 440. Referring to Figure 18B, the high-compression / tensile synthetic fiber material can also be used in the thigh support 450.

[0217] Although not all details are explicitly shown in the figures, some embodiments also include structural features such as reinforcing support plates, breathable fabric portions, or ergonomically contoured shoulder straps (i.e., shoulder strap system 40B).

[0218] Referring to Figures 18E to 18H, in some embodiments, at least a portion of the infant carrier 400 may include a flexible fabric component. This flexible fabric may be stored within or around the waist belt area (i.e., waist belt 42), hip support 440, or head and neck support 410, and when unfolded, may extend to cover a large portion of the outer surface of the infant carrier 400.

[0219] Optionally, the infant carrier 400 may include a covering layer 470 comprising a flexible fabric. The infant carrier 400 is provided with a storage bag 460, within which the covering layer 470 can be folded and stored for easy access during use. Optionally, the storage bag 460 may be located within or around the waist belt 42 or the torso support 430. For example, the storage bag 460 may be located within or around the waist belt 42, hip support 440, or head and neck support 410. When the covering layer 470 is unfolded, its coverage area may include at least the torso support 430, the harness support 420, or the head and neck support 410.

[0220] Fabric materials can be mixed or treated with functional coatings, such as waterproof or UV-resistant coatings. The embodiments shown in Figures 18E to 18H illustrate this type of hybrid material construction.

[0221] Referring to Figures 18E-18H, in some embodiments, the infant carrier 400 further includes a protective layer attached to at least a portion of the carrier support 420, hip support 440, head and neck support 410, torso support 430, or thigh support 450. The protective layer may include waterproof fibers, wherein waterproof fibers are fibers obtained by mixing or treating a flexible fabric with a waterproof coating. Optionally, the protective layer includes UV-resistant fibers, wherein UV-resistant fibers are fibers obtained by mixing or treating a flexible fabric with a UV-resistant coating. The protective layer may serve as a protective structure of the infant carrier 400 in this embodiment or as part of such a protective structure.

[0222] Optionally, the protective layer may also include a high-strength synthetic material, such as a high-compression / tensile synthetic fiber material, which may include, but is not limited to, ultra-high molecular weight polyethylene (UHMWPE) fiber, para-aramid fiber, liquid crystal polymer fiber, or other engineering fibers suitable for lightweight reinforcement applications.

[0223] In some embodiments, the cover layer 470 may be a protective layer. Other embodiments may also include overall safety and comfort features such as an adjustable harness system, shock-absorbing padding, or modular fastening elements. Different designs may also include different strap geometries, closure mechanisms, and body contours to accommodate caregiver preferences and different infant sizes or postures. These embodiments collectively represent a family of wearable infant support devices (an example of infant carrier 400) designed to enhance safety, comfort, adaptability, and ease of use in a variety of applications.

[0224] Figures 19A-20 illustrate a pet carrier 500, which includes a carrier shell 510 made of a high-strength synthetic material. This structure provides puncture resistance and structural stability, making the pet carrier 500 suitable for both vehicle restraint systems and hand-held applications. The high-strength synthetic material can be, for example, a high-strength synthetic fiber material, specifically, a high-compressive / tensile-strength synthetic fiber material. Exemplarily, the carrier shell 510 can be made of a polymer material, with at least a portion of its outer surface covered by the high-strength synthetic fiber material. This high-strength synthetic fiber material can be adhered to the polymer shell (i.e., the carrier shell 510) using an adhesive.

[0225] In some embodiments, the polymer shell (i.e., shell 510, or carrier shell) may have a microporous structure to improve adhesion and breathability, facilitating the secure bonding of synthetic fiber materials using adhesives. Furthermore, high compressive / tensile strength synthetic fiber materials may also be attached to the inner surface of the carrier shell 510. The area covered by the high-strength synthetic fiber material may vary depending on the specific embodiment.

[0226] As shown in Figures 19A-20, a carrier (such as a pet carrier 500) includes a body (covered by a shell 510, not shown), the shell 510, and a protective layer (not shown). The body defines an enclosing structure with an interior for accommodating an animal, and the body includes a cavity. The shell 510 is configured to enclose the body. The protective layer may be attached to the shell, for example, the inner surface of the shell 510. The protective layer may include a high-stress resistant material (or high-strength synthetic material), which includes synthetic fibers (e.g., high compressive / tensile synthetic fiber materials). The protective layer may serve as a protective structure of the pet carrier 500 in this embodiment or as part of such a protective structure.

[0227] In some examples, synthetic fiber materials are made into honeycomb fabrics and can be applied to the openings or windows 520 of the pet carrier 500, as shown in Figures 19 and 20. This ensures both the strength of the openings or windows 520 and allows for some ventilation.

[0228] Figure 21 shows a structural schematic diagram of a child car seat 600 according to an embodiment of the present disclosure. The child safety seat 600 (such as a booster seat) may include a seat body 60A and a base 60B. The seat body 60A may include a seat portion 640, a backrest 630, and a headrest 650. Side wings 631 are provided on the sides of the backrest 630. The child car seat 600 may serve as an example of a child restraint system or as part of a child restraint system.

[0229] Referring to Figure 21, the child car seat 600 includes a side impact protection element (i.e., a SIP element 610) made of a high-strength synthetic material. The high-strength synthetic material can be a synthetic fiber material, such as a high-compression / tensile synthetic fiber material, which may include, but is not limited to, ultra-high molecular weight polyethylene (UHMWPE) fibers, para-aramid fibers, liquid crystal polymer fibers, or other engineered fibers suitable for lightweight reinforcement applications. The SIP element 610 is designed to absorb and deflect lateral forces (e.g., lateral impact forces) in the event of a side collision. The SIP element 610 is disposed on the outer side of the seat body 60A. The outer side of the seat body 60A refers to the side of the seat body 60A that faces away from the child when the child is seated in it.

[0230] In some embodiments, the SIP element 610 or a portion thereof may comprise a honeycomb fabric structure similar to that described in Figures 19 and 20, providing an optimal balance of strength, energy absorption, and lightweight structure.

[0231] This honeycomb-shaped fiber material can be integrated into the internal structure of specific components, particularly those used for impact protection. The honeycomb structure is used in the SIP element 610. The SIP element 610 can be attached to areas such as the side wings 631, headrest 650, shoulder area 632, or hip area 641 of a child car seat 600. The inner side of the SIP element 610 can be formed of a honeycomb synthetic fiber structure, or alternatively, the honeycomb structure can be attached to the synthetic fiber material forming the SIP element 610. Furthermore, the synthetic fiber material can be applied to other critical areas to provide additional protection in the event of a collision.

[0232] In other words, the SIP element 610 may include a SIP body and a protective layer (not shown), the SIP body being made of a synthetic fiber material. The protective layer may be formed of a honeycomb synthetic fiber structure (as shown in Figure 21). The protective layer may be integrated into the SIP body, for example, attached to the inside of the SIP body, and forming the inner surface of the SIP element 610. Optionally or alternatively, the protective layer may be attached to the outer surface of the SIP body.

[0233] The protective layer can serve as a protective structure of the child restraint system in this embodiment, or as part of that protective structure.

[0234] Figures 22 to 24 are schematic diagrams of a child car seat 600 according to an embodiment of the present disclosure. The child car seat 600 can be used as an example of a child restraint system or as part of a child restraint system.

[0235] Figures 22 to 24 illustrate a rib structure 620 mounted on the seat to enhance rigidity along critical load paths. A child safety seat, such as a booster seat, includes a seat 640, a backrest 630, and a headrest 650, with side wings 631 on either side of the backrest 630. In one embodiment, reinforcing structures (e.g., rib structure 620) are incorporated into the side wings 631 to increase strength while reducing weight and maintaining overall mass. These reinforcing structures can be made entirely of high-strength synthetic materials, high compressive / tensile synthetic fiber materials, or the material can be applied as an outer layer to the side wings 631. High-strength synthetic materials include, for example, high compressive / tensile synthetic fiber materials, which may include, but are not limited to, ultra-high molecular weight polyethylene (UHMWPE) fibers, para-aramid fibers, liquid crystal polymer fibers, or other engineered fibers suitable for lightweight reinforcement applications. In some cases, the reinforcing structure including high compressive / tensile synthetic fiber material is located in the upper region of the side wings 631.

[0236] In other words, the side wing 631 is provided with a rib structure 620, which includes a protective layer, which may be made of a high compressive / tensile strength synthetic fiber material. Optionally, the rib structure 620 is the protective layer; or, the protective layer is attached to the inner or outer side of the rib structure 620 to reinforce the rib body. Thus, the rib structure 620 enhances the impact resistance of the side wing 631. The protective layer may serve as a protective structure of the child restraint system in this embodiment or as part of such a protective structure.

[0237] Figures 25-27 are schematic diagrams of a child car seat 600 according to an embodiment of the present disclosure. Figure 28 shows a schematic diagram of the seat portion 640 (i.e., booster seat) of the child car seat 600 in Figure 25; Figure 29 shows a cross-sectional view of the child car seat 600 in Figure 25. The child car seat 600 can be used as an example of a child restraint system or as part of a child restraint system.

[0238] As shown in Figures 25-27 and 29, the child car seat 600 includes a seat 640, a backrest 630, and a headrest 650. The seat 640 may be, for example, a booster seat. The headrest 650 is movably disposed on the backrest 630 and can move up and down relative to the backrest 630 to adjust the height of the headrest 650. The seat 640 and the backrest 630 are detachably connected.

[0239] Figures 25-27 and 29 illustrate the backrest 630 of a child car seat 600, with side wings 631 provided or formed on the left and right sides of the backrest 630. The backrest 630 includes a plurality of reinforcing members 635 made of a high-strength synthetic material. The high-strength synthetic material may be, for example, a high compressive / tensile strength synthetic fiber material, which may include, but is not limited to, ultra-high molecular weight polyethylene (UHMWPE) fiber, para-aramid fiber, liquid crystal polymer fiber, or other engineered fibers suitable for lightweight reinforcement applications. In some embodiments, the reinforcing members 635 may be elongated members made of a high compressive / tensile strength synthetic fiber material, and this material may be applied to their front and rear outer surfaces to enhance the overall strength and durability of the backrest assembly.

[0240] Figure 28 shows the booster seat with the backrest removed (i.e., seat 640), demonstrating another usage mode (i.e., backless mode). The backrest 630 is detachably connected to the seat, allowing the child safety seat to switch between high-back and backless modes. In high-back mode, the backrest 630, seat 640, and headrest 650 are used together. In backless mode, the seat 640 can be used alone.

[0241] Figures 30 and 31 illustrate the connecting member 660 associated with the backrest 630 and the booster seat (i.e., the seat portion 640), respectively. In some cases, the connecting member 660 may include a connecting hook 661, a connecting rod 662, and a connecting hole 663. The connecting hook 661 is disposed on the backrest 630, specifically at the lower end of the backrest 630. The connecting rod 662 is disposed on the seat portion 640, specifically at the rear end of the seat portion 640. The connecting rod 662 connects to the seat portion 640 and together with the seat portion 640 forms the connecting hole 663. The connecting hole 663 is for inserting the connecting hook 661 of the backrest 630 into it to engage with the connecting rod 662. Specifically, the end of the connecting hook 661 may pass through the connecting hole 663 and engage with the connecting rod 662. These connecting components 660 (such as connecting hooks 661, connecting rods 662, and connecting holes 663) can be made of or reinforced with high-strength synthetic materials to ensure a secure connection and allow for repeated adjustments without mechanical damage. Specifically, the high-strength synthetic material is, for example, a high-compression / tensile synthetic fiber material, which may include, but is not limited to, ultra-high molecular weight polyethylene (UHMWPE) fibers, para-aramid fibers, liquid crystal polymer fibers, or other engineered fibers suitable for lightweight reinforcement applications. The connecting components 660 (such as hooks 661, rods 662, and holes 663) used to connect the backrest 630 and the seat 640 can be made of or reinforced with high-compression / tensile synthetic fiber materials. This structure improves the strength, abrasion resistance, and durability of the connecting components, thereby improving structural integrity in impact events and extending the lifespan of the child safety seat.

[0242] In other words, the child car seat 600 includes a protective layer made of a high-strength synthetic material, such as a high-compression / tensile synthetic fiber material. The sidewalls of the connecting rod 662, connecting hook 661, and connecting hole 663 may be made of or have a protective layer attached to them. The protective layer may serve as a protective structure of the child restraint system in this embodiment or be part of that protective structure.

[0243] [Corrected according to Rule 91, 05.06.2026] For example, the connecting hook 661 is made of a high compressive / tensile synthetic fiber material, or a high compressive / tensile synthetic fiber material may be attached to the outer surface of the connecting member 660 to improve the strength and abrasion resistance of the connecting member 660. Connecting members 660 on the seat 640 (such as connecting rod 662 and connecting hole 663) are made of a high compressive / tensile synthetic fiber material, or a high compressive / tensile synthetic fiber material may be attached to the outer surface of the connecting member 660 to improve the strength and abrasion resistance of the connecting member. This material can improve integrity in the event of an accident or give the child car seat 600 a longer service life.

[0244] Figures 32 and 33 are schematic diagrams of the structure of a child safety seat base 700 according to an embodiment of the present disclosure.

[0245] Figures 32 and 33 show a car seat base (or child safety seat base, or simply base) 700 including a seat belt tensioner 710 for adjusting and securing the tension of the car seat belt. In one embodiment, the tensioning component (i.e., the seat belt tensioner 710) is made of a high-strength synthetic material to improve strength and durability.

[0246] In some cases, child safety seat bases include a LATCH retainer plate 740 (or LATCH retainer cover) and a seatbelt tensioner plate 710. The seatbelt tensioner plate 710 works by rotating from the open position to the locked or closed position, coiling up the LATCH seatbelt (not shown) or vehicle seatbelt (not shown) to eliminate seatbelt slack. The LATCH retainer plate 740 allows the LATCH seatbelt to slide in a groove formed between the LATCH retainer plate 740 and the modular base structure. When the LATCH system is engaged, i.e., when the LATCH seatbelt is in the use position, the LATCH retainer plate 740 holds the seatbelt in the correct installation position.

[0247] In some embodiments, the high-strength synthetic material may be, for example, a high-compression / tensile synthetic fiber material, which may include, but is not limited to, ultra-high molecular weight polyethylene (UHMWPE) fiber, para-aramid fiber, liquid crystal polymer fiber, or other engineering fibers suitable for lightweight reinforcement applications. High-compression / tensile synthetic fiber materials can be used in the structures of the LATCH fixing plate 740 and the seatbelt tensioner 710. For example, the LATCH fixing plate 740 and the seatbelt tensioner 710 may be made entirely of high-compression / tensile synthetic fiber material, or the high-compression / tensile synthetic fiber material may be coated as a reinforcing layer on the surface of the LATCH fixing plate 740 and the seatbelt tensioner 710. The use of high-strength synthetic materials, particularly high-compression / tensile synthetic fiber materials, can improve structural integrity in impact events, contributing to improved durability and lifecycle performance of the LATCH fixing plate 740 and the seatbelt tensioner 710.

[0248] Figures 34A-34B show schematic diagrams of the structure of a child restraint system according to some embodiments of the present disclosure.

[0249] As shown in Figures 34A-34B, in one embodiment, the child restraint system includes a base 700 and a seat (i.e., seat body) 900. The seat 900 is rotatably mounted on the base 700, allowing the seat 900 to switch between a forward-facing position (see Figure 34B) and a rearward-facing position (see Figure 34A). The base 700 is secured within the vehicle by a vehicle seatbelt (or car seatbelt, not shown) or a LATCH (Lower Anchors and Tethers for Children) system (not shown) and serves to provide structural support and anchoring points for the seat 900. The seat 900 provides a seating surface for a child occupant. The child restraint system is designed to effectively transfer impact forces from the seat 900 through the base 700 to the vehicle structure. The child restraint system has at least two usage modes, including a rearward-facing configuration and a forward-facing configuration. When the seat 900 is in the rearward-facing position, the child restraint system is in the rearward-facing configuration; when the seat 900 is in the forward-facing position, the child restraint system is in the rearward-facing configuration.

[0250] Figure 34C is a partial schematic cross-sectional view of a child restraint system according to an embodiment of the present disclosure, showing the engaging mechanism 720 of the child restraint system, wherein the child restraint system is in a forward configuration.

[0251] To facilitate the effective distribution of loads in a collision event, the seat 900 and the base 700 are equipped with interlocking hook rails—collectively referred to as the engagement mechanism 720—mounted as high as functionally feasible on the seat 900 to transfer the massive collision load from the seat 900 to the base 700 and then to the vehicle.

[0252] In some embodiments, when a child is seated in the seat 900, the rearward-facing track on the seat 900 may be located directly below the child's feet (as shown in Figure 34A), while the forward-facing track may be located near the child's shoulders (as shown in Figure 34B). The base 700 is provided with corresponding upper and lower tracks that engage with the tracks of the seat 900. The tracks of the seat 900 may be engaging hooks 722 capable of engaging with engaging tracks 721.

[0253] Referring to Figures 34C-35B, the engaging mechanism 720 includes an interlocking hook track (or engaging track 721) on the base 700 and a corresponding engaging hook 722 on the seat 900, designed with a profile that rotates about a rotation axis, thereby allowing the corresponding engaging hook 722 on the seat 900 to rotate to lock into engagement with the base 700. The engaging track 721 includes an upper track (or upper engaging track 721a) and a lower track (or lower engaging track 721b). Accordingly, the engaging hooks (or seat tracks) of the seat 900 include an upper engaging hook 722a capable of engaging with the upper engaging track 721a and a lower engaging hook 722b capable of engaging with the lower engaging track 721b. The engaging track 721 includes a track recess and a hook body of the engaging hook 722 that can extend into the engaging track 721, such that the engaging track 721 engages with the engaging hook 722. When the child restraint system is in the rear-facing configuration, the upper engaging hook 722a on the seat 900 engages with the upper engaging track 721a on the base 700; when the child restraint system is in the forward-facing configuration, the lower engaging hook 722b on the seat 900 engages with the lower engaging track 721b on the base 700.

[0254] The locking mechanism 720 may be made of a high-strength synthetic material, or a high-strength synthetic material may be attached to the surface of the locking mechanism 720. In some embodiments, the interlocking hook track (i.e., locking track 721) and the corresponding hook (i.e., locking hook 722) may be made of a high compressive / tensile strength synthetic fiber material, or such material may be applied as a reinforcing layer to (e.g., attached to) the surface of these components (e.g., the locking mechanism 720 including the locking track 721 and the locking hook 722). The use of high-performance synthetic fiber materials in these load-bearing components provides structural support in impact events, improves overall integrity, and contributes to improving the overall durability and service life of the child restraint system.

[0255] In other words, the child restraint system includes a protective layer, which can be made of a high-strength synthetic material, such as a high tensile / compressive strength synthetic fiber material. The protective layer can form the engaging hook 722 and engaging track 721 of the engaging mechanism 720, or the protective layer can be attached to the surface of the engaging hook 722 and engaging track 721. The protective layer can serve as a protective structure of the child restraint system in this embodiment, or as part of that protective structure.

[0256] Figure 36 shows a three-dimensional structural schematic diagram of a child restraint system according to an embodiment of the present disclosure.

[0257] [Correction based on Rule 91, 05.06.2026] Referring to FIG36, the rotating child restraint system includes a base 800 and a seat (i.e., seat body) 900, wherein the seat 900 is configured to rotate at least between a rearward position and a forward position. The child car seat (i.e., the seat 900 of the child restraint system) includes a front edge 901, which is at least partially made of a high-strength synthetic material. In other words, the front edge 901 is provided with or formed as a reinforcing area. The front edge 901 facilitates load transfer and provides comfort for the occupant. The seat is provided with a seating space 902 with an opening for the child to sit in, the edge of the opening of the seating space 902 serving as the outer edge of the seat 900. The front edge 901 is part of the outer edge of the seat 900 and is located generally below the outer edge of the seat 900.

[0258] In some embodiments, the high-strength synthetic material is, for example, a high-compression / tensile synthetic fiber material, which may include, but is not limited to, ultra-high molecular weight polyethylene fibers, para-aramid fibers, liquid crystal polymer fibers, or other engineering fibers suitable for lightweight reinforcement applications. The leading edge 901 of the seat 900 may be made of or reinforced with a high-compression / tensile synthetic fiber material. For example, the high-compression / tensile synthetic fiber material may be integrated into the structure of the leading edge 901 or attached to the surface of the leading edge 901. The use of a high-compression / tensile synthetic fiber material helps improve the structural performance of the seat, including improving structural performance in the event of an impact (e.g., the structural integrity of the seat 900), and ensuring long-term durability (i.e., extending the service life of the seat 900).

[0259] In other words, the child restraint system includes a protective layer made of a high-strength synthetic material, which may be formed as a leading edge 901 or attached to the surface of the leading edge 901. The protective layer may serve as a protective structure of the child restraint system in this embodiment, or as part of such a protective structure.

[0260] When seat 900 is used on car seat 1A00 in rearward mode (i.e., rearward position), the leading edge 901 containing high compressive / tensile synthetic fiber material can abut against car seat back 1A10 (or vehicle seat back) to provide a rebound damping effect.

[0261] In some embodiments, the leading edge 901 may include two arcuate structures. During tilt adjustment, the leading edge 901 may follow an arcuate movement path, which helps to maintain consistency in the distance or contact interface between the leading edge 901 of the seat and the backrest 1A10 of the vehicle seat. Maintaining consistency in the contact interface between the leading edge 901 of the seat and the backrest of the vehicle seat 900 can be understood as ensuring that the leading edge 901 of the seat 900 remains in contact with the backrest 1A10 of the vehicle seat.

[0262] Figures 37A to 37E illustrate various tilt positions of the seat 900, each providing a different tilt angle. The seat 900 can be adjusted between at least two different tilt positions on the base 800. As can be seen from Figures 37A to 37E, in the rearward position, the tilt angle of the seat 900 relative to the base 800 increases sequentially, and the contact point between the front edge 901 and the car seat back 1A10 moves upward along the car seat back 1A10. When the seat 900 is in the rearward mode, the front edge 901 of the seat 900 can abut against the car seat back 1A10 in different tilt positions, thereby providing a shock absorption effect for the seat 900.

[0263] Figures 38A, 38B, and 39 show a positioning groove 820 formed on a base 800, wherein the positioning groove 820 is at least partially made of a high-strength synthetic material. In other words, the protective layer of the child restraint system can form the groove wall of the positioning groove 820 or be attached to the groove wall of the positioning groove 820.

[0264] As shown in the cross-sectional view of Figure 39, the positioning groove 820 is configured to interact (e.g., engage) with a corresponding protrusion on the seat housing, thereby guiding and securing the seat 900 during installation.

[0265] In one embodiment, the rotating child restraint system includes a base 800 and a seat 900 rotatable at least between a rearward and a forward position. The seat 900 includes a seat housing and a locking assembly 910 disposed on the seat housing. The seat 900 can be positioned relative to the base 800 in a forward and rearward position by engaging the locking assembly 910 with the base 800. To ensure accurate alignment and secure engagement of the locking assembly 910 of the seat 900 and the base 800 in these positions, the base 800 includes two positioning slots 820 symmetrically arranged relative to the seat's axis of rotation S. Specifically, the locking assembly 910 includes an engaging portion 911 movably disposed within the seat housing. At least a portion of the engaging portion 911 can extend out of the seat housing to form a protrusion and engage with one of the positioning slots, thereby positioning the seat 900 in a forward or rearward position.

[0266] It should be noted that the number of positioning slots 820 is not limited to two. The number of positioning slots 820 can be determined according to the number of usage modes that need to be positioned. For example, when the child restraint system seat 900 is configured to also be used in other usage modes between the forward and rearward positions, additional positioning slots can be provided at the corresponding positions between the two positioning slots. In other words, the number of positioning slots 820 can be greater than two, and this disclosure does not limit this.

[0267] Referring to Figures 38A-39, when the seat 900 is in the forward position, the locking component 910 on the seat 900 is aligned with one of the positioning slots 820; when the seat 900 is in the rearward position, the locking component 910 on the seat 900 is aligned with the other positioning slot 820. In some embodiments, the positioning slot 820 may be made of or reinforced with a high compressive / tensile strength synthetic fiber material. For example, such material may be integrally formed with or applied to (e.g., attached to) the inner surface of the positioning slot 820 to improve abrasion resistance and ensure long-term durability under repeated use.
