It should be understood that the installation of the tension spring 2, the shielding sheet 3 and the shielding sheet push rod 4 on the headrest bottom cover 1 is only for example and not for limitation, and the tension spring 2, the shielding sheet 3 and the shielding sheet push rod 4 can also be respectively mounted on the headrest front cover (see Figure 1 It should be understood that the tension spring 2 is only used as an example and not as a limitation, and elastic members such as torsion springs can also be used in the present utility model.

[0029] like Figure 4 As shown, the headrest bottom cover 1 has a slide groove 12 , and the shielding piece 3 is slidably mounted on the headrest bottom cover 1 through the slide groove 12 to cover the through hole 11 as needed.

[0030] like Figure 5 As shown, the middle portion of the shielding sheet 3 has a laterally extending limiting portion 31, such as Figure 6 As shown, the slide groove 12 has a stopper 13. When the shielding piece 3 is slidably assembled onto the headrest bottom cover 1, the limiting portion 31 is squeezed and deformed by the stopper 13 and then rebounds to prevent the shielding piece 3 from escaping from the slide groove 12 during the sliding process.

[0031] like Figure 5 As shown, the shielding sheet 3 has four protrusions 32, such as Figure 7As shown, the protrusion 32 cooperates with the outer edge 121 of the slide groove 12 to ensure the lateral stability of the shielding sheet 3 during the sliding process.

[0036] exist Fig. 9 In the open state shown, the tension spring 2 exerts a force on the shielding plate push rod 4 to make it rotate counterclockwise, so that the shielding plate 3 completely covers the through hole 11. At this time, the arc edge 35 at the bottom of the shielding plate 3 (see Figure 5 ) against the headrest rod 5. During the folding process of the headrest, the headrest rod 5 moves in the through hole 11 and abuts against the shielding sheet 3 through the arc edge 35 so that it is in the slide groove 12 (see Figure 4 ) moves, the baffle push rod 4 rotates around the mounting column 14 until Fig.11 Shown in folded state.

[0037] Unlike traditional blocking covers, the utility model blocks the through hole 11 through the blocking sheet 3. The blocking sheet 3 slides in close contact with the headrest plug rod 5 throughout the entire process to avoid the problem of fingers accidentally falling into the slot and pinching the hand during operation, protecting the safety of passengers' fingers. Whether on the side or the back, the blocking sheet 3 has a good shielding effect, the appearance is flat and has no pits, and it is safe and reliable during use. With the help of the setting of the blocking sheet push rod 4, the blocking stroke of the blocking sheet 3 can reach more than 50mm, so that the flip angle of the headrest can reach more than 90°, covering the problem of headrest rod avoiding slot hole shielding in most of the current folding headrests, and solving the long-stroke shielding problem that the current torsion spring blocking sheet structure cannot achieve. Regardless of the state of the headrest, the utility model can effectively block the through hole 11 through the blocking sheet 3, and the blocking sheet 3 can be automatically slid and reset through the tension spring 2, solving the appearance problems of incomplete shielding and uneven pits in the appearance of fixed blocking covers on the market. In summary, the headrest strip hole shielding structure of the utility model occupies a small space, is suitable for most high and low folding headrests, is simple and convenient to assemble, has strong parts versatility, and has a high shielding piece platform degree.
