It should be pointed out that all the drawings are exemplary representations. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0024] The present invention will be further described in detail below through specific implementation examples in conjunction with the accompanying drawings.

[0025] Reference Figures 1 to 4 A plastic unlocking device for a car seat headrest rod comprises a body 1 and a button 2. The body 1 is connected to a headrest bracket of a seat back, and the button 2 is connected to the body 1. The button 2 is used to lock the seat headrest rod and unlock the seat headrest rod. The body 1 and the button 2 are preferably plastic parts. The body 1 and the button 2 can be an integrally molded part or a split part.

[0026] The main body 1 includes a clamping portion 11 and a shielding portion 12. The clamping portion 11 is connected to a headrest bracket (not shown), and the shielding portion 12 is connected to the clamping portion 11. At the same time, a button 2 is connected to the shielding portion 12. In one embodiment, the clamping portion 11 includes a plurality of claws 111, which are clamped to the headrest bracket of the seat back through the claws 111.

[0027] The button 2 includes a folding portion 21, an unlocking portion 22, and a pin 23. The folding portion 21 is connected to the shielding portion 12, and the unlocking portion 22 is connected to the folding portion 21. The folding portion 21 is a locally weakened area. A folding groove 211 is formed on the folding portion 21. The two side edges of the folding portion 21 are formed with inclined edges 212. The inclined edges 212 are provided to enable the folding portion 21 to be smoothly arched and folded upward when unlocked, and not to interfere with other adjacent parts. A headrest rod insertion hole 221 is formed in the middle part of the unlocking portion 22. The unlocking portion 22 is used to lock or unlock the seat headrest rod. When unlocking, by pressing the unlocking portion 22, the folding portion 21 begins to fold upward at the folding groove 211, and the unlocking portion 22 is separated from the card slot of the headrest rod to complete unlocking. After releasing the unlocking portion 22, the folding portion 21 is reset through elastic deformation, and the unlocking portion 22 is engaged with the card slot of the headrest rod to complete locking.

[0028] In another embodiment, a slide groove 121 is formed on the shielding portion 12, a fixing hole 122 is formed at the end of the slide groove 121, and pins 23 are provided on both sides of the folding portion 21 and the unlocking portion 22. In the locked state, the pin 23 is located in the fixing hole 122, and the pin 23 on the unlocking portion 22 moves along the slide groove 121 during the unlocking or locking process.

[0029] The following will refer to Figures 1 to 4 The working principle of the utility model is described.

[0030] When the unlocking part 22 is pressed, the folding part 21 begins to fold upward at the folding groove 211, and the unlocking part 22 is separated from the slot of the headrest rod, and the unlocking is completed; after the unlocking part 22 is released, the folding part 21 is reset by elastic deformation, and the unlocking part 22 is engaged with the slot of the headrest rod, and the locking is completed. Compared with the traditional button, the utility model has a simple structure and saves costs.

[0031] The above are only specific implementations of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
