Abstract
Description
[Technical Field]
[0001] The present invention relates to the technical field of baby products, and more particularly to a seat belt adjustment structure and a child safety seat. [Background technology]
[0002] Baby seats are almost a necessity for babies, and in the prior art, many safety seats are adjustable to accommodate children of different sizes. While seat adjustment allows the headrest to be adjusted to an appropriate position to accommodate children of different sizes, it is difficult to adjust the seat belt to an appropriate position. Most seat belt adjustment structures are complicated and cumbersome to operate, and it is difficult to reasonably change the position of the seat belt to an appropriate position when adjusting the height of the headrest, which brings about certain inconvenience for users.
[0003] Therefore, there is a need for a seat belt adjustment mechanism that allows the seat belt to be adjusted to the appropriate position to accommodate different users.
[0004] A child safety seat is a seat designed for children. By assembling the child safety seat inside a vehicle so that the child can ride in it, the child is restrained by the child safety seat and ensures the child's safety while traveling. As shown in FIG. 19, a conventional child safety seat 200a includes a seat 201a and a seat belt 202a that is drilled through the seat. The seat belt 202a has a buckle 203a shaped like a sash that is located in front of the seat 201a. The buckle 203a is used to adjust the length of the seat belt so that the seat belt can securely restrain the child in the seat 201a. However, the conventional child safety seat 200a has the following problems. First, when the seat belt 202a is in use, the portion of the seat belt 202a located between the front of the seat 201a and the buckle 203a can slide downward along the buckle 203a, causing the seat belt to loosen and the child to be unable to be safely restrained in the seat 201a, posing a safety risk. Second, because the buckle 203a is located in the front of the seat 201a, when a child uses the child safety seat, the buckle 203a can squeeze the child's shoulders, causing discomfort to the child.
[0005] Therefore, there is a need to provide a child safety seat that can prevent the seat belt from slipping off during use. Summary of the Invention [Problem to be solved by the invention]

[0050] In order to explain the technical contents and structural features of the present invention in detail, the following examples are combined and further explained in conjunction with the drawings.
[0051] 1 to 6 and 16 to 18, the present invention provides a child carrier 100, which includes a carrier body 101 and a seat belt adjustment structure 10 provided on the carrier body 101. The seat belt adjustment structure 10 is suitable for adjusting the position of a seat belt of the child carrier 100. Here, the carrier body 101 may be a stroller, a sleeping box, a car safety seat, or the like. The seat belt adjustment structure 10 can adjust the position of a seat belt on the stroller, sleeping box, or car seat belt. Specifically, the seat belt adjustment structure 10 includes a support member 11 movably provided on the child carrier 100, and the support member 11 is provided with multiple rows of adjustment portions 12 at different heights for restraining the seat belt. The position of the seat belt is adjusted by the movement of the support member 11 on the child carrier 100 and the cooperation of the seat belt and the adjustment portions 12 at different heights. The side of the support member 11 is provided with openings 16 that communicate with at least two rows of adjustment parts 12, and the openings 16 allow the seat belt to cooperate with adjustment parts 12 of different heights to adjust the position of the seat belt relative to the child's shoulders.
[0052] With the above-described configuration, the child carrier 100 of the present invention is provided with a seat belt adjustment mechanism 10 on the carrier body 101, allowing the position of the seat belt relative to the child's shoulders to be adjusted on the carrier body 101. The child carrier 100 of the present invention is adaptable to children of various sizes and body shapes, and allows for convenient seat belt adjustment and more comfortable use. The seat belt adjustment mechanism 10 of the present invention includes a support member 11 movably mounted on the child carrier 100, with multiple rows of adjustment portions 12 at different heights provided on the support member 11, and the seat belt can cooperate with the different adjustment portions 12. Specifically, the position of the seat belt can be adjusted by moving the support member 11, allowing the seat belt position to be more suited to the user. Furthermore, the seat belt can be adjusted by cooperation of different adjustment portions 12 with the seat belt so that the seat belt can be adapted to different users. Of course, the position of the support member 11 on the carrier body 101 may be adjusted while the position of the different adjustment portions 12 of the seat belt on the support member 11 is adjusted so that the seat belt is more suited to children of different sizes and body shapes. The seat belt adjustment structure 10 of the present invention can adjust the position of the seat belt so that the seat belt is adapted to different users. The seat belt adjustment structure 10 of the present invention not only adjusts the position of the seat belt by the support member 11, but also adjusts the position of the seat belt by the cooperation of different adjustment portions 12 on the support member 11 with the seat belt, which has a simple structure, convenient operation, and greater adaptability.
[0053] 1 to 8 , in some optional embodiments, the carrier body 101 is provided with a backrest 40 and a headrest 20 that can be adjusted up and down on the backrest 40. Here, the seat belt adjustment structure 10 can be linked to the headrest 20, and when the headrest 20 is adjusted up and down, the seat belt adjustment structure 10 rises and falls along with the headrest 20. For example, the support member 11 may be connected to the headrest 20, or the seat belt adjustment structure 10 may be directly provided on the headrest 20, or the support member 11 and the headrest 20 may be integrally formed. In some embodiments, the support member 11 can also move relative to the headrest 20. The specific structure and connection method of the support member 11 and the headrest 20 can be set according to actual needs. Since the seat belt adjustment structure 10 is linked to the headrest 20, it rises and falls in synchronization with the rise and fall of the headrest 20. Therefore, the seat belt adjusting structure 10 and the headrest 20 can be adjusted to a reasonable position at once to fit children of different body types. Also, the seat belt can be adjusted to a different adjustment part 12 depending on the child's weight level, so that the position is suitable for the user and more comfortable to use.
[0054] 1 to 8 , in some optional embodiments, a first seat belt passage member 211 is provided on the inner plate 21 of the headrest 20, so that when an older child uses the child carrier 100 of the present invention, the seat belt of the vehicle seat can be passed through the first seat belt passage member 211 to protect the riding child. On the other hand, when a younger child uses the child carrier 100 of the present invention, the first seat belt passage member 211 allows the position of the headrest 20 to be more easily adjusted, thereby making it easier to adjust the movement of the support member 11 by the headrest 20 so that the seat belt is positioned within an appropriate range within the support member 11 according to the user's size and body shape. Furthermore, cooperation between the seat belt and the different adjustment member 12 makes use of the seat belt more comfortable. In this embodiment, a second seat belt passage member 42 is provided on the backrest 40, so that when the seat belt adjustment structure 10 on the carrier body 101 is used, the seat belt of the vehicle seat can pass through the second seat belt passage member 42 to secure the child carrier 100 to the vehicle seat and for safer use. The second seat belt passage member 42 also allows the entire carrier body 101 to move more easily. The seat belt of the vehicle seat passes through the first seat belt passage member 211 or the second seat belt passage member 42 when engaging with the child carrier 100. The first seat belt passage member 211 and the second seat belt passage member 42 ensure that the seat belt of the vehicle seat can reliably protect a child riding in the child carrier 100 without affecting the child's riding comfort. The provision of the first seat belt passage member 211 and the second seat belt passage member 42 can effectively reduce the weight of the carrier body 101, resulting in a lighter overall weight and saving on materials. The child carrier 100 of the present invention can be flexibly adapted to children of various sizes and shapes and is comfortable to use.
[0055] 8 and 13, in some alternative embodiments, the headrest 20 includes an inner plate 21 and a cover 22. The inner plate 21 is connected to the support member 11 or is integral with the support member 11. The cover 22 is detachably fitted onto the inner plate 21, and the outer shape of the cover 22 matches the inner plate 21. The cover 22 has a flexible structure to provide a more comfortable fit when a user leans against the headrest 20. The cover 22 is also removable and easier to clean. When the cover 22 is fitted onto the inner plate 21, the adjustment portions 12 on the support member 11 are located outside the cover 22, allowing the adjustment portions 12 to better cooperate with the seat belt, and the seat belt to be more easily adjusted between the multiple adjustment portions 12. The structure is simple and the design is rational.
[0056] 7, 14 and 15, in some alternative embodiments, the child carrier 100 is provided with a lift adjustment structure 30 that is matched to the support member 11, and the support member 11 is provided with an engagement member 14 that is matched to the lift adjustment structure 30, and the engagement member 14 engages with different positions of the lift adjustment structure 30 to position the support member 11 at different positions on the child carrier 100. Here, the engagement member 14 may be provided on the support member 11, or if the seat belt adjustment structure 10 is provided on the headrest 20, the engagement member 14 may be provided on the headrest 20. The engagement member 14 is located on a mating surface of the support member 11 or the headrest 20 and the backrest 40, and the lift adjustment structure 30 is located on the backrest 40, and by cooperation of the engagement member 14 and the lift adjustment structure 30, the headrest 20 and the support member 11 can be positioned at different positions on the backrest 40 to accommodate different users. Specifically, the lift adjustment structure 30 is provided with a plurality of engagement holes 31 engageable with the engagement members 14, and the engagement members 14 engage with different engagement holes 31 to adjust the position of the support member 11. The engagement members 14 are movably mounted on the headrest 20 or the back surface of the support member 11 via fixing members 15, and the engagement members 14 engage with different engagement holes 31 to adjust the positions of the headrest 20 and the support member 11 on the back surface 40. When the engagement members 14 are operated to disengage from the engagement holes 31, the headrest 20 and the support member 11 are unlocked and slide relative to the backrest 40 to adjust the positions of the headrest 20 and the support member 11. When the headrest 20 and the support member 11 are slid and adjusted to the appropriate position, the headrest 20 and the support member 11 are movably engaged with the corresponding engagement holes 31 via the engagement members 14 so as to be locked to the backrest 40, resulting in a simple structure and convenient adjustment.
[0057] 6, in some optional embodiments, the carrier body 101 has mounting holes 41 for inserting and attaching seat belts, and the seat belts cooperate with different adjustment parts 12 in the mounting holes 41. Note that the seat belts are fixed to the carrier body 101, pass through the mounting holes 41 in the backrest 40, and can cooperate with the adjustment parts 12 of the support member 11.
[0058] 1 to 12 , in some optional embodiments, the adjustment portion 12 is a groove structure 120 through which a horizontal seat belt movably passes. Note that a seat belt generally has an elongated shape, and the adjustment portion 12 has the groove structure 120 so that the horizontal seat belt can movably pass through the groove structure 120. Here, the groove structure 120 may be elongated so as to fit the horizontal seat belt. Specifically, the length of the groove structure 120 is longer than the width of the seat belt, and the width of the groove structure 120 is wider than the thickness of the seat belt. This allows the seat belt to pass smoothly through the groove structure 120 and prevents the seat belt from overlapping when passing through the groove structure 120, resulting in more comfortable use.
[0059] 1 to 12 , in some optional embodiments, the groove structures 120 of the corresponding adjustment portions 12 in two adjacent rows are connected to each other. Specifically, the groove structures 120 of the corresponding adjustment portions 12 in two adjacent rows are connected to each other by a vertical groove structure 13 through which a vertical seat belt slides. The seat belt can slide from one groove structure 120 to the other groove structure 120 through the vertical groove structure 13. When the seat belt is not removed, the seat belt can slide from one groove structure 120 to the other groove structure 120, making it easier to adjust the position of the seat belt. Meanwhile, the vertical groove structure 13 prevents the seat belt from sliding from one groove structure 120 to the other groove structure 120 by itself, and only the groove-shaped seat belt can slide, so that the seat belt is more securely stopped within the groove structure 120. Here, the connection between the groove structure 120 and the longitudinal groove structure 13 is an arc-shaped portion 121, and the specific shape of each arc portion 121 can be set according to the actual transition situation. The arc-shaped transition between the groove structure 120 and the longitudinal groove structure 13 allows the seat belt to slide more smoothly, reduces friction between the groove structure 120 and the longitudinal groove structure 13 and the seat belt, and extends the life of the seat belt. For example, the longitudinal groove structure 13 may be a vertical stripe structure or another structure, such as an arc shape, as long as a vertical seat belt can pass through it. Alternatively, the longitudinal groove structure 13 may be semicircular, with the middle section of the semicircular longitudinal groove structure 13 having a large storage space, which can improve the alignment of the seat belt sliding within the longitudinal groove structure 13 and adjust any twisted seat belt, making the seat belt more comfortable to use. Of course, the longitudinal groove structure 13 may also be another structure with a large storage space in the middle section as long as the storage space allows for adjustment of the seat belt. The minimum width of the longitudinal groove structure 13 is greater than the thickness of the seat belt, thereby allowing the seat belt to slide smoothly within the longitudinal groove structure 13.
[0060] 8 to 12 and 17 and 18 , in some optional embodiments, a first position limiting portion 122 may be provided between the groove structure 120 and the longitudinal groove structure 13 or the opening 16, and the first position limiting portion 122 may limit the sliding of the seat belt within the groove structure 120. A second position limiting portion 123 may be provided between the groove structure 120 and the first position limiting portion 122 to limit the sliding of the seat belt within the groove structure 120. The first position limiting portion 122 and / or the second position limiting portion 123 may protrude higher than the thickness of the seat belt within the adjustment portion 12, and may more firmly position the seat belt within the adjustment portion 12 to prevent the seat belt from accidentally sliding out of the adjustment portion 12. In one embodiment, as shown in Fig. 9, first position limiting portions 122 having a curved structure may be provided between some of the groove structures 120 and the longitudinal groove structures 13, and the first position limiting portions 122 protrude below the groove structures 120, thereby preventing the belt from sliding freely when the belt is in the groove structures 120 and stabilizing the structure. That is, the first position limiting portions 122 may be partially provided between the groove structures 120 and the longitudinal groove structures 13, and partially not provided. In another embodiment, as shown in Fig. 10, first position limiting portions 122 are provided between all of the groove structures 120 and the longitudinal groove structures 13 so that the seat belt does not slide freely when the seat belt is in the groove structures 120 and the structure is more robust. In some embodiments, as shown in Fig. 12, a second position limiting portion 123 may be further provided between the groove structure 120 and the first position limiting portion 122, and the provision of the second position limiting portion 123 may reinforce the stop of the seat belt within the groove structure 120, allowing the seat belt to be stopped more stably within the groove structure 120 and making the structure more stable. In yet another embodiment, as shown in Fig. 17, the first position limiting portion 122 may be provided between the groove structure 120 and the opening 16, and the second position limiting portion 123 may be provided between the first position limiting portion 122 and the groove structure 120.18, a longitudinal groove structure 13 may be provided between the through-groove structure 120 and the opening 16, a first position limiting portion 122 may be provided between the through-groove structure 120 and the longitudinal groove structure 13, and a second position limiting portion 123 may be provided between the first position limiting portion 122 and the through-groove structure 120. Each adjustment portion 12 may be directly connected to the longitudinal groove structure 13 or the opening 16. The first position limiting portion 122 may be provided between each adjustment portion 12 and the longitudinal groove structure 13 or the opening 16 to limit the movement of the seat belt within the adjustment portion 12. The first position limiting portion 122 and the second position limiting portion 123 may be provided together between each adjustment portion 12 and the longitudinal groove structure 13 to allow the seat belt to stop more stably within the adjustment portion 12. The shape of the second position limiting portion 123 may be set according to actual usage needs. For example, the second position limiting portion 123 may have a wave-like structure, the specific number of wave-like protrusions and recesses of which is not particularly limited.
[0061] Referring to FIGS. 16 and 18 , in some alternative embodiments, openings 16 are provided on the side of the support member 11, connecting at least two adjacent rows of through-groove structures 120. The openings 16 allow the seat belt to switch between different adjustment sections 12. Alternatively, the openings 16 can be provided directly on the side of the support member 11 and connect to multiple adjustment sections 12 on the same side.
