[0039] In some embodiments of the present invention, reference is made to... Figure 3 , Figure 4 and Figure 6 As shown, the support part 2 includes a first support plate 21, a second support plate 22, and a rotation adjustment mechanism 23. The rotation adjustment mechanism 23 connects the first support plate 21 and the second support plate 22. The second support plate 22 is connected to the main body part 1. The second support plate 22 can be fixedly connected to the main body part 1, or it can be movably connected to the main body part 1. The second support plate 22 is located between the first support plate 21 and the main body part 1. The first support plate 21 is adapted to support the head and neck of the occupant 200. The rotation adjustment mechanism 23 is used to adjust the angle between the first support plate 21 and the second support plate 22. Specifically, the rotation adjustment mechanism 23 has an unlocked state and a locked state. In the unlocked state, the first support plate 21 and the second support plate 22 are rotatably connected so that the support angle for the head and neck of the occupant 200 can be adjusted by rotating the first support plate 21. In the locked state, the first support plate 21 and the second support plate 22 are fixedly connected so that the first support plate 21 is held at the adjusted support angle.

[0040] In some embodiments of the present invention, the rotation adjustment mechanism 23 includes a rotating shaft, a bearing, a ratchet, and a pawl. One of the rotating shaft and the bearing is mounted on a first support plate 21, and the other is mounted on a second support plate 22. The first support plate 21 and the second support plate 22 are rotatably connected through the cooperation of the rotating shaft and the bearing. The ratchet is fixedly connected to the rotating shaft. When the rotation adjustment mechanism 23 is in the unlocked state, the pawl disengages from the ratchet, allowing the ratchet and the rotating shaft to rotate freely. At this time, the first support plate 21 can be rotated to adjust its support angle for the head and neck of the occupant 200. When the rotation adjustment mechanism 23 is in the locked state, the pawl locks the ratchet to prevent the ratchet and the rotating shaft from rotating, and the first support plate 21 remains at the adjusted support angle.

[0041] In some embodiments of the present invention, reference is made to... Figure 3 , Figure 4 and Figure 6As shown, the included angle α between the first support plate 21 and the second support plate 22 satisfies the following relationship: 0°≤α≤90°. When α equals 0°, the first support plate 21 and the second support plate 22 are in contact. When 0°<α≤90°, the first support plate 21 and the second support plate 22 are at least partially separated, so that the first support plate 21 can be adjusted to a suitable angle according to the needs of the occupant 200. In the event of a collision, the gap between the separated parts of the first support plate 21 and the second support plate 22 can provide space for the deformation of the first support plate 21 to buffer the impact on the head and neck of the occupant 200.

[0042] In some embodiments of the present invention, reference is made to... Figures 3-7 As shown, the support part 2 also includes a movable adjustment mechanism 24, which connects the second support plate 22 and the main body part 1. The movable adjustment mechanism is used to adjust the position of the second support plate 22 relative to the main body part 1. The second support plate 22 can be movably connected to the main body part 1 through the adjustment mechanism. By adjusting the position of the second support plate 22 relative to the main body part 1, the position of the first support plate 21 can be changed to adjust the support position of the first support plate 21 on the head and neck of the occupant 200.

[0043] In some embodiments of the present invention, reference is made to... Figures 3-7 As shown, the movable adjustment mechanism 24 includes a connecting part 241 and a limiting part 242. The connecting part 241 is fixedly connected to the second support plate 22, and the limiting part 242 is fixedly connected to the main body 1.

The height direction of the headrest can be... Figures 3-6 The up and down directions in the middle.

[0044] In some embodiments of the present invention, reference is made to... Figures 3-7As shown, the connecting part 241 includes a first sub-connecting part 2411 and a second sub-connecting part 2412. The main body 1 is provided with a lifting guide groove. The first sub-connecting part 2411 and the limiting part 242 are both provided inside the main body 1. Multiple limiting grooves 24111 are provided in the first sub-connecting part 2411. The second sub-connecting part 2412 passes through the lifting guide groove and is fixedly connected to the second support plate 22 and the first sub-connecting part 2411. The lifting guide groove can limit the movement direction of the second sub-connecting part 2412 relative to the main body 1. The limiting part 242 can be installed with... The rod 12 is fixedly connected, and the limiting part 242 has a limiting protrusion 2421 suitable for limiting and cooperating with the limiting groove 24111. The limiting protrusion 2421 is a telescopic structure and can extend and retract in the front and rear directions. It can push the first support plate 21 upward or downward to move the first sub-connecting part 2411 relative to the limiting protrusion 2421 and change the limiting groove 24111 on the first sub-connecting part 2411 that cooperates with the limiting protrusion 2421, so as to realize the lifting and lowering movement of the first support plate 21 relative to the main body 1.

[0045] In some embodiments of the present invention, the hardness of the main body 1 is greater than that of the support 2. The support 2 is softer to improve user comfort, while the main body 1 is harder to reduce the deformation of the support 2 when the vehicle collides, thus protecting the head and neck of the occupant 200 and ensuring the headrest 10 provides support for the head and neck.

[0046] In some embodiments of the present invention, the hardness of the second support plate 22 is greater than that of the first support plate 21. The first support plate 21, which is in direct contact with the head and neck of the occupant 200, is softer to improve user comfort.
