Description

Technical Field

[0001] The present invention belongs to the field of seats, and particularly relates to a headrest for a children's seat. Background Art

[0002] Children's seats have become an important device to ensure the safety of children during travel. The headrest design of children's seats plays a crucial role in protecting children's heads and necks. Common children's seats include: children's seats fixed on car seats, children's seats fixed on bicycles, and baby strollers.

[0003] In addition to being comfortable, children's seats are more importantly required to support and protect the vulnerable heads. Therefore, a headrest for supporting children's heads is needed.

[0004] In the patent with the publication number CN101731880A and the invention name "Children's Seat", a typical children's seat is disclosed. In the Figure 4 drawing of which, the headrest part is disclosed. In order to increase buffering, the headrest part is made thick, looking bloated. And generally, the headrest part uses fluffy materials to cover the bracket to achieve the buffering effect. Such fluffy materials are not only easy to hide dirt and grime, but also gradually cause local collapse during use. If a waterproof fabric is used to cover it, the breathability will be lost. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a headrest for a children's seat with mechanical buffering, which can replace the buffering of fluffy materials and the headrest tilts synchronously when the child's body tilts, in view of the above-mentioned current situation of the prior art.

[0006] The technical solution adopted by the present invention to solve the above technical problem is as follows: A headrest for a children's seat includes a headrest body padded behind the head. The headrest body is connected with a main support frame, and the main support frame is connected with a backboard, and the backboard is fixed on the seat.

[0007] Symmetric first wing plates and second wing plates are provided behind the headrest body. A first elastic component is connected between the first wing plate and the backboard, and a second elastic component is connected between the second wing plate and the backboard; gaps are respectively provided between the first wing plate, the second wing plate and the headrest body. When encountering an accelerating or bumpy section, the child's head will press on the headrest body, and the headrest body will press on the first wing plate and the second wing plate. The first wing plate will be buffered by the first elastic component, and the second wing plate will be buffered by the second elastic component. The split first wing plate and second wing plate can independently support the pressure on the child's back. In this way, when the child's body presses on one side of the first wing plate, the child's head can also press on the headrest body on the side of the first wing plate accordingly. This can avoid the injury caused by the reverse torsion of the head and body when the child's body tilts.

[0008] In a preferred embodiment, a slide rail mechanism is provided between the main support frame and the back plate for the main support frame to move up and down. By adjusting the height of the main support frame, the height between the child's head and the headrest body can be adjusted.

The first stepped surface and the second stepped surface face the front of the child seat to prevent the first wing plate and the second wing plate from disengaging forward; the first wing plate is provided with a third stepped surface that abuts against the slider, and the second wing plate is provided with a fourth stepped surface that abuts against the slider. The third stepped surface and the fourth stepped surface face the rear of the child seat to isolate the child from the moving slide rail mechanism.

[0012] In a preferred embodiment, the headrest body includes a main headrest plate fixed to the main support frame and a pair of sub-headrest plates respectively disposed on both sides of the main headrest plate. A rotating shaft is connected between the main headrest plate and the sub-headrest plates.

[0013] In a preferred embodiment, corrugated friction portions are respectively provided between the main headrest plate and the sub-headrest plates to increase the resistance of the sub-headrest plates to rotate; first stop strips are respectively provided on both sides of the main headrest plate, and the sub-headrest plates are provided with second stop strips. The first stop strips are located between the second stop strips and the child's head to limit the excessive folding of the sub-headrest plates. If the first stop strips and the second stop strips are not provided, the two sub-headrest plates are easily folded by accidental impact, which may easily cause the child's head to be pinched.

[0014] In a preferred embodiment, the sub-headrest plates are provided with third stop strips, and the first stop strips are located between the second stop strips and the third stop strips. The third stop strips are used to limit the excessive unfolding of the sub-headrest plates.
