Description

Technical Field

[0001] This utility model relates to the field of seat device technology, specifically to child safety seats. Background Technology

[0002] Child safety seats are common items in daily life. They generally include the seat body, an elastic membrane or pad covering the corresponding surface of the seat body, and a seat belt assembly. The installation straps usually include shoulder straps, crotch straps, and groin straps to better restrain the corresponding parts of the child or infant. The drawback is that the seat belt can be relatively loose, posing a safety hazard, and needs to be improved. Utility Model Content

[0003] To address at least one of the aforementioned technical deficiencies, this utility model provides the following technical solution:

[0004] This application discloses a child safety seat, including a seat body. The seat body has a groove on the side facing the child or infant for a corresponding seat belt to extend from, and a hook on the side of the body adjacent to the groove for the corresponding seat belt to pass through. A gap is reserved between the hook and the lower side of the body for the corresponding seat belt to pass through.

[0005] This solution adds hooks, allowing the corresponding seat belts to wrap around the hooks. For example, the shoulder straps or crotch straps of the seat belt can wrap around the hooks. Under the guidance and connection of the hooks, the seat belts can be kept in a relatively taut state, which can better restrain and protect the children in the seat.

[0006] Furthermore, the body has grooves at intervals on its hip support surface for connecting the crotch strap in the seat belt, and hooks at intervals on the hip support surface between adjacent grooves for the seat belt to wrap around. The hooks are located near the grooves, and the crotch strap can be in a relatively taut state after wrapping around the hooks. The placement of the grooves near the grooves can free up more space for children or infants to ride.

[0007] Furthermore, the main body has a second groove on its hip support surface for connecting the groin strap of the seat belt, and a hook for the seat belt to wrap around is provided on the hip support surface between the second groove and the back support surface of the main body. The hook is located adjacent to the second groove, and the groin strap can be in a relatively taut state when wrapping around the hook. The proximity of the second groove can free up more space for children or infants to ride.

[0008] Furthermore, the main body has three grooves at intervals on the back support surface for connecting the shoulder strap in the seat belt, and a hook for the seat belt to wrap around is provided on the back support surface between the three grooves and the hip support surface in the main body. The hook is located adjacent to the three grooves, and the shoulder strap can be in a relatively taut state after wrapping around the hook. The placement adjacent to the three grooves can free up more space for children or infants to ride.

[0009] Furthermore, the hook is integrally formed with the body, simplifying the forming process.

[0010] Furthermore, a mounting groove is provided on the main body surface, and the hook is at least partially located in the mounting groove. Gaps are reserved between the front and rear of the hook and the corresponding mounting groove wall, as well as below the hook, for the seat belt to pass through. The fact that the hook is partially or completely located in the mounting groove helps to make the main body surface flat and improves the comfort of children riding in it.

[0011] Furthermore, one end of the hook is connected to the corresponding body surface while the other end is disconnected from the body surface, facilitating the wrapping of the seat belt.

[0012] Furthermore, it also includes a stop block, which is hinged to a hook connected to the crotch strap and located at the end of the hook that is disconnected from the body. The hook and its side groove wall form a cavity for the crotch strap to extend out. An entrance for the crotch strap to enter the cavity is formed between the end of the hook that is disconnected from the body and its side groove wall. The stop block can be rotated to open or close the entrance. After the crotch strap enters the cavity, the stop block can be rotated to close the entrance to restrict the crotch strap from disengaging.

[0013] Furthermore, the main body includes a base and a back connected to the base. The back includes a back panel and a cushion. The cushion and the back panel are connected by detachable fasteners. The back panel is provided with multiple fastening grooves that cooperate with the fasteners along the longitudinal direction to facilitate adjustment of the cushion position.

[0014] Furthermore, the fastener includes a bolt and a matching nut, and a groove is formed in the middle of the path formed by multiple fastening grooves along the path extension direction. The groove is used to allow the bolt to move up and down. The width of the groove is smaller than the diameter of the fastening groove, which facilitates the adjustment of the pad position.

[0015] Furthermore, it also includes a seat belt, which includes a crotch strap, shoulder straps, hip straps and a connecting strap. The crotch strap, shoulder straps and hip straps extend from corresponding grooves. The connecting strap is located in the cavity of the base. One end of the connecting strap is connected to a retractor provided on the base and the other end of the connecting strap is connected to the end of the shoulder strap at the back of the back. The tightness of the shoulder strap can be adjusted as needed.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0026] Example 1

[0027] like Figure 1 , Figure 2 As shown, in this example, the child safety seat includes the seat body 1, which adopts a conventional configuration, such as the backrest 11 being installed on one side of the base 10 to form an L-shaped body 1.

[0028] In this example, the main body 1 has a groove formed on the side facing the child or infant for the corresponding seat belt to extend from, and a hook 19 is formed on the main body side adjacent to the groove for the corresponding seat belt to pass through. A gap is provided below the hook 19 for the corresponding seat belt to pass through. Specifically... Figure 1As shown, a seat belt typically includes a shoulder strap 23, a crotch strap 20, and a groin strap 22. Taking the shoulder strap as an example, the main body 1 has grooves 16 at intervals formed on the back support surface for connecting the shoulder strap in the seat belt. The back support surface is the side of the main body 1 where the back 11 faces the child or infant. One end of the shoulder strap 23 is connected to the groove 16. A hook 19 for the seat belt to wrap around is formed on the back support surface between the groove 16 and the hip support surface (i.e., the top surface of the base 10) in the main body 1. The hook 19 is located adjacent to the groove 16. After the shoulder strap 23 wraps around the hook 19, it can be in a relatively taut state.

[0029] To improve riding comfort, in this example, a mounting groove 17 is formed on the back support surface, and the hook 19 is located at the opening of the mounting groove 17. The top surface of the hook 19 is flush with the end face of the groove opening. Gaps are reserved between the hook 19 and the corresponding mounting groove 17 wall, as well as below the hook 19, for the seat belt to pass through. These gaps form a passage for the shoulder strap to pass through. Figure 1 As shown. In addition, preferably one end of the hook 19 is connected to the back support surface at the slot, and the other end of the hook 19 is disconnected from the adjacent back support surface, so that the shoulder strap can be inserted into the cavity from the disconnected gap.

[0030] In this example, the main body 1 has grooves 18 spaced out on its hip support surface (i.e., the top surface of the base) for connecting the lap belt in the seat belt. Hooks 19 for the seat belt to pass through are spaced out on the hip support surface between adjacent grooves 18, with the hooks 19 positioned adjacent to the grooves 18. These hooks are also located at the opening of a mounting groove formed on the hip support surface. If flush with the surface, the gaps at the front, back, and bottom of the hooks form a cavity for the lap belt to pass through. One end of the hook 19 is connected to the hip support surface, while the opposite end is disconnected from the adjacent hip support surface. The lap belt 20 can be in a relatively taut state after passing through the hooks.

[0031] In this example, the main body 1 has a groove 21 formed at its hip support surface for connecting the groin strap 22 of the seat belt, as shown in the example. Figure 1 As shown, groove 21 and groove 18 are triangularly distributed. A hook 19 for the seat belt to pass through is formed on the buttock support surface between groove 21 and the back support surface of the body 1. The hook 19 is located adjacent to groove 21. The hook 19 is also located at the opening of the mounting groove formed on the buttock support surface. If it is flush, the gaps at the front, back and bottom of the hook form a cavity for the groin strap to pass through. One end of the hook 19 is connected to the buttock support surface, while the other end is disconnected from the adjacent buttock support surface. The groin strap can be in a relatively taut state after passing through the hook.

[0032] The shape of the hook can be selected according to requirements, such as straight, curved, or triangular. In this example, only a straight bar-shaped hook 19 is shown. The hook is preferably integrally molded with the body, such as by injection molding. Of course, the hook can also be molded independently and then fixed at the corresponding surface.

[0033] You can also add stops, such as Figure 3 As shown, the stop block 2 is hinged to the hook 19 connected to the crotch strap 22 and is located at the end of the hook 19 that is disconnected from the body. The hook 19 and the groove wall on one side form a cavity 100 for the crotch strap to extend out. The end of the hook 19 that is disconnected from the body and the groove wall on one side form an entrance for the crotch strap 22 to enter the cavity. Rotating the stop block opens or closes the entrance. Figure 3 The indicated position shows the stop block in the closed inlet position. After the crotch belt enters the cavity, the stop block can be rotated to close the inlet and prevent the crotch belt from disengaging. The hinged structure of the stop block can be selected from the market according to requirements.

[0034] In this example, to accommodate children of different heights, the back structure has been modified. The backrest 11 includes a back panel 111 and a back cushion 110. The bottom of the back panel 111 is connected to the base 10, and the back cushion 110 is installed on the front of the back panel 111. The back cushion can be molded from the required material, such as a hard or elastic material. The back cushion 110 and the back panel 111 are connected by detachable fasteners. Multiple fastening grooves 14, which mate with the fasteners, are formed longitudinally on the back panel 111. The fasteners consist of common bolts 12 and nuts 13. The end of the bolt 12 passes through the hole formed in the back cushion 110 and the corresponding fastening groove 14, and then the nut is screwed on. In this example, for easy adjustment, a slide groove 15 is formed in the middle of the path formed by multiple fastening grooves 14 along the path extension direction. The slide groove allows the bolt to move up and down, and the width of the slide groove 15 is smaller than the diameter of the fastening groove 14. When adjustment is needed, if the nut is loosened, the pad can be moved up and down, and the bolt moves along the slide groove accordingly. After it moves to the required fastening groove, the nut can be tightened.

[0035] To make it easier to adjust the tightness of the shoulder straps, such as Figure 4 As shown, in this example, the safety belt includes a crotch strap 22, shoulder straps 23, crotch straps 20, and a connecting strap 24. The crotch straps 22, shoulder straps 23, and crotch straps 20 extend from their corresponding grooves. The connecting strap 24 is located in the cavity of the base 10. One end of the connecting strap 24 is connected to the retractor 3 installed on the base 10, and the other end of the connecting strap 24 extends from the cavity of the base 10 and is connected to the end of the shoulder strap 23 at the back of the back panel 11. The ends of the shoulder strap and the connecting strap can be directly tied together, sewn together, or the ends of the shoulder strap and the connecting strap can be connected to the same plate. When in use, the connecting strap can be pulled out as needed to adjust the tightness of the shoulder strap.
