When the supporting plate is subjected to a small external force, the torque of the torsion spring torsional deformation is balanced with the external force. At this time, the stiffness of the spring is greater than that of the torsion spring, so the deformation is small; At the same time, it is subjected to a huge external force. If the spring is not provided, the occupant's head will be injured due to the rigid pressure or excessive support of the rotating shaft. With the buffer of the spring, the supporting strength of the rotating shaft can reach Appropriate degree. the

As a preference, the rotating shaft is connected to the seat headrest by means of a support plate adjustment shaft, one end of the support plate adjustment shaft is horizontally fixed on the left or right side of the seat headrest, and the other end of the support plate adjustment shaft is connected to the seat headrest. The rotating shaft is orthogonally pivoted, and a locking screw is provided at the pivotal joint. Loosen the locking screw, turn the rotating shaft around the supporting plate adjustment axis at an appropriate angle and then re-tighten the locking screw; adjusting the angle or inclination of the rotating shaft can make the height and inclination of the side pillow adapt to the needs of members of different heights. the

Preferably, there are two side pillows, symmetrically arranged at the left and right ends of the seat headrest. There are protective pillows at the left and right ends, so that the occupant can lean to the left or the right to rest at will. When the car encounters a side collision, no matter whether it is a left or right collision, it will be safe. the

Preferably, a sponge-like pad is provided on the pallet. Padded, spongy padding provides comfort and added cushioning in the event of a side impact. the

The beneficial effects of the utility model are:

1. The headrest of the car seat can effectively protect the head of the occupant and reduce the damage to the neck position;

2. It can improve the comfort and safety of passengers.
