[0026] Please refer to Figures 1 to 4 As shown, it shows the specific structure of a preferred embodiment of the utility model, which is a car safety headrest.

[0027] Among them, the side frame 30 is arranged on the support part 11, and the angle A between the side frame 30 and the support part 11 is between 90-180°. After the flexible block 20 wraps the side frame 30, the baffle 40, the support part 11, and the bending part 12, the flexible block 20 can support the back side of the head, as well as the left and right sides of the head, which is safer and more comfortable.

[0028] The present application provides a car safety headrest, comprising a main frame 10, a flexible block 20, a side frame 30, a baffle 40, and a wrapping skin 50; the main frame 10 is bent to form a support portion 11, a bending portion 12, and a pin portion 13 in sequence; the baffle 40 is arranged on the support portion 11, and a limited position tooth 14 is arranged on the pin portion 13; the side frame 30 is arranged on the support portion 11, and the angle A between the side frame 30 and the support portion 11 is between 90-180°; the flexible block 20 wraps the main frame 10, and the pin portion 13 extends from the flexible block 20; the wrapping skin 50 wraps the flexible block 20. The main frame 10, the side frame 30, and the baffle 40 are preferably made of stainless steel or aluminum alloy, and can be combined together by screws or welding technology, and welding is preferably used in this embodiment. There is a certain angle between the side frame 30 and the support part 11, so when the flexible block 20 wraps the main frame 10, the side frame 30, and the baffle 40, the flexible block 20 will extend a certain length to the left and right sides to form the side support part 21. The side support part 21 of the flexible block 20 can well support the left and right sides of the head, and the rear support part 22 supports the back of the head. It can be seen that the flexible block 20 can support the back of the head and the left and right sides of the head, and the safety and comfort are better. The angle A between the side frame 30 and the support part 11 is between 90-180°, preferably any value among 115°, 120°, 135°, 150°, and 160°. The pin part 13 extends from the flexible block 20 and can be inserted into the seat to facilitate the installation of the headrest. The limiting teeth 14 prevent the head from falling off and play an upper and lower limiting role. The main frame 10 is an integrated structure, which is formed by bending to sequentially form a support portion 11, a bending portion 12, and a pin portion 13. The outer wall of the pin portion 13 is provided with teeth, so that the seat can be easily clamped on the pin portion 13 during installation.

[0029] Preferably, the first end of the side frame 30 is bent to form a first welding portion 31, and the first welding portion 31 is welded to the support portion 11; the second end of the side frame 30 is bent to form a second welding portion 32, and the second welding portion 32 is welded to the bent portion 12. The first welding portion 31 and the second welding portion 32 increase the connection area between the side frame 30 and the main frame 10, and improve the welding firmness. The first welding portion 31 and the second welding portion 32 of this embodiment are preferably in a straight line shape.

[0030] Preferably, the angle B between the pin portion 13 and the support portion 11 is between 1-10 degrees, such as 1°, 2°, 3°, 5°, 8°, 10 degrees, etc. The pin portion 13 and the support portion 11 are not flat, and this design is conducive to increasing the elasticity of the support portion 11, that is, it can play a better buffering role and improve comfort.

[0031] Preferably, the wrapping skin 50 is provided with a stitching line 52, and the stitching line 52 corresponds to the connection position between the side frame 30 and the support part 11. The stitching line 52 improves the fit between the wrapping skin 50 and the flexible block 20, and the aesthetics are better.

[0032] Preferably, the baffle plate 40 is penetrated with a through hole 41, and the edge of the baffle plate 40 is provided with a forward protrusion 42. The through hole 41 and the protrusion 42 improve the firmness of the connection between the flexible block 20 and the main frame 10, and the firmness is better.

[0033] Preferably, the wrapping skin 50 is one of PU leather, leather, cloth, and mesh. The wrapping skin 50 of this embodiment is PU leather or cloth. Hot melt adhesive is provided on the inner side of the cloth, and can be adhered to the flexible block 20 by hot melt bonding.

[0034] Preferably, the flexible block 20 is one of polyurethane foam, polypropylene foam, and polyethylene foam. The main frame 10, the side frame 30, and the baffle 40 are welded together and placed in a mold, and then a foaming material is injected into the mold. The foaming material is formed into the flexible block 20, and the flexible block 20 wraps the main frame 10, the side frame 30, and the baffle 40.

[0035] Preferably, the inner side surface of the wrapping skin 50 is provided with hot melt adhesive, and the hot melt adhesive is one of EVA hot melt adhesive, PVC hot melt adhesive, PU hot melt adhesive, acetamide hot melt adhesive, PUR hot melt adhesive, and modified PUR hot melt adhesive.

[0036] Preferably, the side frame 30 is in a rhombus, oval, or rectangular shape. The side frame 30 of this embodiment is in a rectangular shape, which enables the side support portion 21 to provide support to the side of the head while having better elasticity and better comfort.

[0037] Preferably, a pipeline is embedded in the flexible block 20, and the wrapping skin 50 is provided with an air hole 51, and the gas pumped into the pipeline by the air pump is blown out from the air hole 51. The input end of the pipeline is connected to the air pump, and the output end of the pipeline is connected to the air hole 51 through the air outlet. The air hole 51 can play a role in ventilation, and the air hole 51 is arranged on the rear support part 22 to improve comfort.

[0038] To sum up, the design focus of the present invention is that the side frame 30 is welded to the support part 11, and the angle A between the side frame 30 and the support part 11 is between 90-180°. Therefore, after the flexible block 20 wraps the side frame 30, the baffle 40, the support part 11, and the bending part 12, the rear support part 22 can support the back of the head, and the side support part 21 can support the left and right sides of the head, which is safer and more comfortable.
