A curved elastic pressure arm 270 is provided on the connecting plate 27, and a wave rail 271 is provided inside the housing 10 for the curved elastic pressure arm 270 to be clamped into;

[0042] The connecting seat 22 of the plastic part has a certain deformation recovery ability, so the headrest 1 can slide on the grooved track 21 on the main adjustment arm 20. When sliding, the ball 221 will be stuck in one of the circular grooves at different heights on the grooved track 21, thereby sliding and adjusting the position of the headrest 1. The connecting plate 27 is affected by the elastic force of the curved elastic pressure arm 270 on itself. After overcoming the elastic force, it can move on the wavy rail 271 on the shell 10, thereby further sliding and adjusting the position of the headrest 1. Compared with the prior art, the height of the headrest 1 can be adjusted in a wider range through the cooperation of the two, so that the height adjustment range of the headrest 1 is basically limited to users with a height of 1.68-1.9 meters.

[0043] The working principle and use process of the utility model are as follows: first, the headrest 1 is assembled on the backrest of the seat through the assembly buckle 23 or the pre-installed surface 220 on the connecting seat 22. Then, when in use, the main adjustment arm 20 can be pushed and pulled to make the main adjustment arm 20 slide up and down on the connecting seat 22 through the grooved track 21. At the same time, the shell 10 can be pushed and pulled to make the wave rail 271 in the shell 10 overcome the elastic force of the curved elastic pressure arm 270 on the connecting plate 27, so that the shell 10 slides up and down on the auxiliary adjustment arm 24, thereby adjusting the height of the headrest 1 in a wide range to suit users of different heights. Moreover, the angle of the headrest 1 can be adjusted by rotating the tension adjustment knob 26, so that the headrest 1 rotates on the auxiliary adjustment arm 24 around the pin joint of the positioning pin 25;

[0044] Then, the neck pad 14 can be pushed and pulled to make the wave seat 1220 on the positioning piece 122 at the end of the neck arm 13 overcome the elastic force of the curved elastic pressure plate 1210 on the positioning pressure piece 121 to move, thereby adjusting the distance between the neck pads 14 to ensure that the neck pad 14 can support both sides of the user's neck, and then the pillow pad 11, the neck pad 14 and the neck-fitting surface 110 cooperate to fit and support the user's neck;

[0045] After adjustment, the headrest 1 can effectively protect both sides of the user's cervical spine and maintain a healthy cervical spine support point to achieve the effect of assisting cervical spine support. At the same time, it can maintain blood circulation on both sides of the cervical spine and alleviate the occurrence of cervical spine symptoms.
