Description

Technical Field

[0001] This utility model relates to the field of child safety seats, and in particular to a dual-purpose head guide hook for child safety seats. Background Technology

[0002] A child car seat is a protective device designed specifically for children of different weights. It needs to be scientifically installed in the car according to the child's body size and weight. The child car seat is securely connected to the vehicle body through seat belts and other means. In the event of sudden braking, collisions, or other emergencies, it can cushion the impact and restrict the child's body movement, greatly reducing the risk of injury to the child. It is a core piece of equipment to ensure the safety of children when traveling in a car.

[0003] In existing technologies, the head guide structure of child safety seats typically uses a rectangular structure for the key connection point that mates with the seat belt. While this rectangular structure allows operators to quickly remove or place the seat belt during daily use, it has significant limitations in its applicable scenarios: When the seat is in a forward-facing, upright position, the seat belt passes normally through the guide structure and fits against its inner wall, forming basic protection. However, when the seat is switched to a rear-facing, reclining position, the rectangular structure lacks a two-way restraint design for the seat belt. As a result, the seat belt will accumulate on one side of the guide structure's inner wall due to gravity. This not only causes noticeable wrinkles in the seat belt and hinders its normal movement, but also accelerates wear due to concentrated stress and repeated friction at the wrinkles, thus shortening the seat belt's lifespan. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a dual-purpose head guide hook for child safety seats, which aims to improve the problem in the prior art that "the rectangular structure lacks a two-way limiting design for the seat belt, which leads to a reduction in the service life of the seat belt".

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a dual-purpose head guide hook for a child safety seat, which is installed on the seat body. A connecting block is slidably connected to the upper surface of the seat body, and a headrest is fixedly connected to the front end of the connecting block. A safety belt is installed on the outer wall of the headrest. A guide hook is installed on the left side of the connecting block. The guide hook is generally configured as a G-shape. The safety belt passes through the center of the guide hook. An opening adapted to the safety belt is provided on the side of the guide hook near the center of the headrest.

[0006] As a further description of the above technical solution:

[0007] The guide hook includes a fixed seat, a guide seat, a surrounding seat, a guide groove, and a protrusion. The fixed seat is installed on the outer wall of the connecting block.

[0008] As a further description of the above technical solution:

[0009] The front end of the mounting base is provided with a protrusion.

[0010] As a further description of the above technical solution:

[0011] The front end of the fixed base is provided with a surrounding seat, and the surrounding seat is configured as a C-shaped structure.

[0012] As a further description of the above technical solution:

[0013] The upper surface of the surrounding seat is provided with a guide seat, which is configured as a conical structure.

[0014] As a further description of the above technical solution:

[0015] A guide groove is provided at the connection between the lower end of the fixed base and the right end of the surrounding base.

[0016] As a further description of the above technical solution:

[0017] The guide hook is hollow at the end near the center of the headrest.

[0018] As a further description of the above technical solution:

[0019] The fixed seat, guide seat, surrounding seat, guide groove, and protrusion are manufactured as a single piece.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the guide hooks fixedly connected to the left and right sides of the connecting block allow the seat belt to pass through the central hollow structure of the guide hook when the seat is in a forward-facing, vertical position, and fit tightly against the inner wall of the hollow structure. This restrains the seat belt and allows it to extend and retract in an emergency to provide protection. When the seat is in a rear-facing, reclined position, the guide hooks on the left and right sides of the connecting block form a symmetrical limiting structure, limiting both ends of the seat belt. Even if the seat is tilted, the seat belt will not pile up to one side due to gravity. At the same time, the hollow structure provides a certain space for the seat belt. Thus, the guide hooks always guide the seat belt, ensuring its protective performance. This solves the problem of seat belt wrinkling caused by the lack of bidirectional limiting design for the seat belt in the existing technology due to the rectangular structure. This allows the seat belt to move normally, reduces repeated wear at the wrinkled areas, and extends the service life of the seat belt.

[0022] 2. In this utility model, the guide hooks fixedly connected to the left and right sides of the connecting block, when the seat is in a rear-facing tilted position, have an anti-pinch design between the opening of the guide hook near the center of the headrest and the guide groove. However, in the event of sudden braking or a collision, the seatbelt can smoothly extend and retract within the hollow structure, preventing excessive tightness from compressing the child's fragile head and neck, while also reducing the risk of neck injury due to inertial jerking through close contact with the body.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0029] Reference Figure 1 - Figure 3This utility model provides an embodiment of a dual-purpose head guide hook for a child safety seat, which is installed on the seat body 1. The seat body 1 is the basic load-bearing frame for the entire safety seat and head guide hook. A connecting block 3 is slidably connected to the upper surface of the seat body 1. The connecting block 3 is the central connecting hub of the overall structure. A headrest 2 is fixedly connected to the front end of the connecting block 3. The headrest 2 is used to provide support and cushioning protection. A safety belt 5 is installed on the outer wall of the headrest 2. The safety belt 5 is used to provide cushioning protection. A guide hook 4 is installed on the left side of the connecting block 3. The guide hook 4 is used to reduce the frictional resistance when the safety belt 5 moves and extend the service life of the safety belt 5. The guide hook 4 is generally designed in a G-shape. The safety belt 5 passes through the center position of the guide hook 4. An opening adapted to the safety belt 5 is provided on the side of the guide hook 4 near the center position of the headrest 2. The guide hook 4 includes a fixing seat 41, which is used to achieve rigid fixation between the guide hook 4 and the connecting block 3 to ensure the stability of the guide hook 4 position. A guide seat 42 is also provided. 42 is used to guide the seat belt 5 smoothly into the surround seat 43, avoiding jamming of the seat belt 5 due to improper entry angle. The surround seat 43 is used to realize the annular restraint channel of the seat belt 5, ensuring that the seat belt 5 can be stably fitted and wrinkle-free in different seat states. The guide groove 44 is used to prevent the seat belt 5 from being squeezed and deformed. The protrusion 45 is used to prevent the seat belt 5 from accidentally detaching after being inserted. The fixing seat 41 is installed on the outer wall of the connecting block 3. The front end of the fixing seat 41 is provided with the protrusion 45. The front end of the fixing seat 41 is provided with the surround seat 43. The surround seat 43 is set with a C-shaped structure. The upper surface of the surround seat 43 is provided with the guide seat 42. The guide seat 42 is set with a conical structure. The lower end of the fixing seat 41 and the right end of the surround seat 43 are provided with the guide groove 44. The end of the guide hook 4 near the center of the headrest 2 is set with a hollow structure. The fixing seat 41, guide seat 42, surround seat 43, guide groove 44, and protrusion 45 are manufactured as a single piece.

[0030] Working principle: The operator holds one end of the safety belt 5 and aligns it with the guide seat 42 of the guide hook 4. Because the guide seat 42 has a conical structure, its smooth slope can guide the safety belt 5 to slide naturally along the slope. After the safety belt 5 slides in along the slope of the guide seat 42, it continues to pass through the center of the guide hook 4. The C-shaped opening of the wrap-around seat 43 faces the center of the headrest 2, and the opening size is adapted to the width of the safety belt 5, allowing the safety belt 5 to smoothly enter the interior of the wrap-around seat 43. At the same time, the arc design of the inner wall of the C-shaped wrap-around seat 43 can wrap the safety belt 5 to prevent it from slipping off the side. After the safety belt 5 has completely passed through the center of the guide hook 4, its outer wall fits against the inner wall of the wrap-around seat 43 and the hollow inner wall of the guide hook 4 near the center of the headrest 2, forming a "two-way constraint" to ensure that the safety belt 5 can maintain a stable position even when it is not under force.

[0031] When the child safety seat is in an upright position, the seat belt 5, under the weight and restraint of the child's body, always fits tightly against the hollow inner wall of the guide hook 4 and the inner wall of the wrap-around seat 43 without any gaps or shaking.

[0032] When the seat needs to be switched to the reclining position, the guide hooks 4 on the left and right sides of the connecting block 3 form a symmetrical limiting structure. The two ends of the seat belt 5 are respectively constrained by the wraparound seats 43 on both sides to prevent the seat belt 5 from sliding and piling up to one side due to the seat tilting. The hollow structure of the guide hook 4 near the center of the headrest 2 provides a certain amount of space for the seat belt 5 to move.

[0033] When the seat reclines, the seat belt 5 can move slightly within the hollow structure without being excessively stretched or squeezed. During the reclining process, the opening of the C-shaped wraparound seat 43 always faces the center of the headrest 2 to prevent the seat belt 5 from coming out of the guide hook 4, ensuring that the seat belt 5 is still in an immediately usable state after the switch is completed, without the need to re-thread it.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
