Description

Technical Field

[0001] This utility model relates to the field of child safety seat technology, and in particular to a headrest assembly for head, neck and spine protection in child safety seats. Background Technology

[0002] Child safety seats, as an important automotive safety device, originated in the late 1970s. With increasing attention to automotive safety issues, especially the rising rate of injuries and fatalities among children in traffic accidents, experts began to study how to effectively protect children from car accidents. The earliest child safety seats were designed based on the principle of car seat belts, mainly by fixing the child's position to reduce the impact force during a collision. With the development of technology, the design of child safety seats has gradually incorporated more protective functions, especially with the widespread adoption of rear-facing seats. These seats can better disperse the impact force during a collision, reducing damage to the spine and head, and further improving safety.

[0003] CN222246935U discloses a head and neck protection structure for a vehicle child safety seat, including a mounting plate and a support rod. The support rod is fixedly connected to the mounting plate and is perpendicular to the mounting plate. The support rod is provided with an angle adjustment mechanism. The angle adjustment mechanism is provided with a side plate, which is perpendicular to the support rod. A side protection plate is fixedly connected to the side plate. A side protection buffer mechanism is connected between the side plate and the angle adjustment mechanism. The angle adjustment mechanism includes a limiting protrusion, a first rotating ring, a limiting rotating ring, and a second rotating ring. A guide rod is fixed to the side wall of the second rotating ring, and the guide rod is parallel to the mounting plate.

[0004] This device uses an angle-adjustable side guard plate. With the help of the angle adjustment mechanism, the outer soft cover on the inner side of the side guard plate can fit against the skin of the neck, thus better fixing the child's neck and providing better protection. However, the position of the headrest is relatively fixed, while children grow rapidly and their head and neck positions change continuously. This causes the headrest support to not fit the physiological curve of the neck, affecting the protective support and reducing the comfort during use. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a headrest assembly for head, neck and spine protection for safety seats.

[0006] This utility model is achieved by the following technical solution: a headrest assembly for head, neck and spine protection for a safety seat, including a headrest body, a wing plate fixedly connected to the side of the headrest body, a mounting rod fixedly connected to the bottom of the headrest body, an adjustment mechanism provided on the surface of the mounting rod, and a fitting mechanism provided on the surface of the mounting rod;

[0007] The adjustment mechanism includes an adjustment frame with an adjustment groove on its surface, an adjustment tube fixedly connected to the surface of the mounting rod, a first spring fixedly connected to the inner wall of the adjustment tube, a slider fixedly connected to the inner wall of the adjustment tube, a first lever fixedly connected to the surface of the slider, and a filler block fixedly connected to the inner wall of the adjustment frame.

[0008] As a further improvement to the above solution, the inner wall of the adjusting frame is slidably connected to the surface of the mounting rod, and the surface of the mounting rod is slidably connected to the surface of the filling block.

[0009] As a further improvement to the above solution, the end of the first spring away from the adjusting tube is fixedly connected to the surface of the slider, the surface of the first lever is slidably connected to the inner wall of the adjusting groove, and the surface of the first lever is slidably connected to the inner wall of the adjusting tube.

[0010] Through the above technical solution, by setting an adjustment tube and an adjustment groove, the first lever is pushed to make the slider slide on the inner wall of the adjustment tube, and the first spring is squeezed to control the sliding of the first lever on the inner wall of the adjustment groove, thereby controlling the extension length of the mounting rod to adjust the height of the headrest body. This allows the position of the headrest body to be flexibly adjusted according to the user's height and comfort needs, improving the flexibility of the device.

[0011] As a further improvement to the above solution, the fitting mechanism includes a movable frame, a locking tube fixedly connected to the surface of the movable frame, a second spring fixedly connected to the inner wall of the locking tube, a locking block fixedly connected to the end of the second spring away from the locking tube, a second lever fixedly connected to the surface of the locking block, a slot formed on the surface of the mounting rod, a neck support fixedly connected to the surface of the movable frame, an airbag fixedly connected to the surface of the headrest body, an air supply pipe fixedly connected to the inner wall of the headrest body, and an air valve provided at the end of the air supply pipe away from the airbag.

[0012] As a further improvement to the above solution, the inner wall of the movable frame is slidably connected to the surface of the mounting rod.

[0013] As a further improvement to the above solution, the surface of the card block is slidably connected to the inner wall of the locking tube, the surface of the second lever block is slidably connected to the inner wall of the locking tube, and the surface of the card block is slidably connected to the inner wall of the card slot.

[0014] The above technical solution involves setting up a movable frame and using a second lever to control the sliding of the locking block on the inner wall of the locking tube, thereby disengaging the locking block from the slot. Then, the position of the movable frame is changed, the second lever is released, and the second spring pushes the locking block to move to both sides, re-engaging it in the first lever to fix the movable frame. This adjusts the position of the neck support, making the safety chair more conform to the user's cervical spine physiological curve during use and improving the practicality of the device.

[0015] As a further improvement to the above solution, the number of airbags is set to three, which are vertically and equidistantly arranged on the surface of the headrest body.

[0016] By using the above technical solution, by setting up airbags and blowing air into different airbags through air supply pipes, the expansion degree of different airbags can be controlled to change the stress-bearing curvature of the headrest body, making the headrest body more conform to the shape of the head, and improving the practicality and comfort of the device.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This utility model, by setting an adjustment mechanism, specifically by setting an adjustment tube and an adjustment groove, pushes the first lever to make the slider slide on the inner wall of the adjustment tube, compresses the first spring, and controls the sliding of the first lever on the inner wall of the adjustment groove, thereby controlling the extension length of the mounting rod to adjust the height of the headrest body. This allows the position of the headrest body to be flexibly adjusted according to the user's height and comfort needs, improving the flexibility of the device.

[0019] This invention features a fitting mechanism, specifically a movable frame. A second lever controls a locking block to slide within the locking tube, disengaging the locking block from its slot. The position of the movable frame is then changed, releasing the second lever. A second spring pushes the locking block to move to both sides, re-engaging it in the first lever to fix the movable frame. This adjusts the position of the neck support, making the safety chair more conform to the user's cervical spine's physiological curve, thus improving the device's practicality. Furthermore, by incorporating airbags and controlling their inflation levels through air pipes, the headrest's surface curvature is altered, making it more closely conform to the shape of the head, further enhancing the device's practicality and comfort.
