As described above, the headrest (2) on the seat (1) of the present invention is provided with a front and rear adjustment device between the seat back (11) of the seat (1) and the bracket (4 inch) supporting the headrest (2). (3), and a height adjusting device (4) is arranged on the bracket (4), and a tilt adjusting device (5) is provided between the bracket (40) and the headrest (2), so that the user can use the front and rear The adjustment device (3), the height adjustment device (4) and the tilt adjustment device (5) are designed to adjust the front, rear, south, and low positions of the headrest and their inclination angles according to the needs of the ride, so that the user can ride on the The seat (1) is more comfortable. Through the above implementation description, the present invention has the following advantages: 1. Since the front and rear adjustment devices are arranged between the seat back of the seat and the bracket supporting the headrest, and the height adjustment device is arranged on the bracket, At the same time, a tilt adjusting device is arranged between the bracket and the headrest, so that the user can adjust the front, rear, high and low positions of the headrest and the tilting angle thereof according to the needs of the ride, so that the neck and the head of the user can Get strong support and make it more comfortable when riding on the seat. 2. When the front and rear position adjustment of the headrest is performed, the pressing of the pressing block is performed by interlocking the two latching elements out of engagement with the latches of the nesting seat, so that the bracket can be rotated about the shaft and then proceed The front and rear position of the headrest connected to the upper end of the bracket is adjusted, and after being adjusted to the desired position, the pressing block is released, so that the two latching elements return to the state of engagement with the latch of the nesting seat' and the adjusted head The front and rear positions of the pillow are fixed, so that it is quite convenient and easy to perform the operation of adjusting the front and rear position of the headrest. 3. When the height adjustment of the headrest is performed, the protrusion of the lower bracket is fastened to the slot of any buckle M308019 which is placed on the upper bracket of the lower bracket to reach the upper end of the upper bracket. The height adjustment of the headrest is adjusted, and the height of the adjusted headrest is fixed accordingly. Therefore, it is quite convenient and easy to adjust the height of the headrest. 4. When the tilt angle adjustment of the headrest is performed, the shaft portion of the upper end of the bracket is correspondingly fitted into the arcuate groove of the headrest body, and the engaging component and the locking piece on the protrusion of the headrest body are Correspondingly engaging any of the grooves, the headrest is pivoted about the shaft portion of the bracket to adjust the tilt angle of the headrest provided at the upper end of the bracket, and the adjusted angle is fixed, so that it is being carried out The operation of adjusting the tilt angle of the headrest is quite convenient and easy. In summary, the present embodiment can achieve the expected use of the work '' and the specific structure disclosed, not only has not seen the same product I ', has not been disclosed before the application 'Hang has fully complied with the patent law The provisions and t seeking '爰 application for a new type of patent according to law, _ please review, and grant a patent, it is really good. 12
