[0023] The first embodiment

[0024] Refer to Figures 1 to 3 , a headrest, including a body 1, and a front support portion 2 and a rear support portion 3 are provided at the rear side of the body 1.

[0025] The hardness of the front support portion 2 is less than that of the rear support portion 3. The front support portion 2 is in an arc shape or a U shape with an opening facing forward. The rear support portion 3 includes a connecting block 31 and a support block 32. A gear slot 321 is provided inside the support block 32, and wall teeth 3211 are provided on the inner side wall of the gear slot 321. A slider 311 is fixedly connected to the connecting block 31. The slider 311 is slidably connected to the gear slot 321 in the front and rear directions. The slider 311 and the wall teeth 3211 can be slidably matched and adjusted step by step. Therefore, the relative position of the connecting block 31 and the support block 32 can be adjusted in the front and rear directions.

[0026] The front support portion 2 is rotatably connected to the front end of the rear support portion 3, and the rear support portion 3 is connected to the middle portion of the front support portion 2.

[0027] Preferably, the front support portion 2 can be made of toughened nylon material, and the rear support portion 3 can be made of fiber-reinforced nylon material. The front support portion 2 is arc-shaped. When the headrest is stressed, the front support portion 2 deforms under stress and can well support the human head. The body 1 is rotatably connected to the front support portion 2, and the tilting angle is adjustable. By pushing the rear support portion 3, the headrest can be conveniently adjusted back and forth by using the sliding fit between the slider 311 and the wall teeth 3211, and it has a strong adaptive function.

[0028] A neck support 11 is integrally formed at the bottom of the main body 1. The neck support 11 is used to support the human neck. When the user leans backward, the neck support 11 can well support the person's neck, avoid the neck from hanging in the air and getting tired, and increase comfort.
