The ugly cover 22 and the headrest rear cover assembly 23 are both clamped on the rear side of the headrest front shell frame neck support assembly 48.

[0047] The working principle of the utility model is as follows: after the unlocking button 40 is pressed, the locking pin linkage frame B15, the locking pin linkage frame A16 and the locking pin 21 are driven, and after the neck support is unlocked, the tension of the neck support pop-up tension spring 10 is applied, and the L-shaped rotating arm A6, the L-shaped rotating arm B-left 8, and the L-shaped rotating arm B-right 9 rotate to drive the neck support assembly 45 to the frontmost position, such as Figure 2 After releasing the unlock button 40, the unlock button return spring 39 returns the unlock button 40, and at the same time, the elastic force of the linkage frame B spring 11 and the locking pin spring 20 returns the locking pin linkage frame B15, the locking pin linkage frame A16 and the locking pin 21, and the neck support is locked in the locking hole of the locking plate 7. The L-shaped rotating arm A6 and the headrest frame 2 have limit points at the initial position and the frontmost position to limit the front and rear extreme positions of the neck support. There are several holes in the locking plate 7 to realize several front and rear gears of the neck support. The above structure thus realizes the front and rear adjustment function of the neck support. Pull the front cover assembly 44 of the neck support frame downward with both hands, and the ball 30 is forced to roll out of the arc-shaped groove of the front cover 31 of the neck support frame, and the neck support is adjusted up and down. After the force is released, the elastic force of the ball spring 29 makes the ball 30 stuck in the arc-shaped groove of the front cover 31 of the neck support frame, so that the neck support remains stopped. The waist-shaped hole of the neck support base bracket 32 ​​limits the upper and lower limit positions of the neck support, and the multiple arc-shaped grooves of the front cover 31 of the neck support frame realize multiple gears of the neck support up and down adjustment. The above structure thus realizes the up and down adjustment function of the neck support.

[0048] Therefore, after the utility model is connected to the car seat, it can also be adjusted to multiple gears in the up-down direction and the front-back direction, which can adapt to the use of different groups of people. The utility model integrates a headrest and a neck support at the same time, and is connected to the car seat through the headrest rod 5, which is firmly connected and highly safe. Moreover, a massage air bag is provided at each end of the neck support foam assembly 43 of the utility model, which can provide support and massage functions for the passenger's neck, and has good comfort.

[0049] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be modified and varied in various ways. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
