[0002] With the rapid development of the automotive industry, passengers have increasingly higher demands for the safety and comfort of cars. For car seat headrests, passengers expect the headrests to be adjustable to their body shape, satisfying their comfort needs as much as possible while ensuring safety.

[0003] Patent publication number CN218876994U discloses an electric headrest adjustment mechanism for a car seat, including a seat body and a headrest body disposed on the seat body. A first electric telescopic rod is fixedly connected to the seat body, and the telescopic end of the first electric telescopic rod is fixedly connected to the lower side wall of the headrest body. The headrest body has a cavity, the inner wall of the cavity is made of hard plastic, and a support pillow is provided on the headrest body. The cavity is provided with a telescopic component and a guide component for adjusting the distance of the support pillow.

[0004] To address the issue that existing headrests cannot move forward or backward, current technology involves using telescopic and guiding components. However, this still results in a limited range of headrest functions, leading to a lack of comfort and an inability to meet the needs of different users. Utility Model Content
