Fault in the seat adjustment buttons. Below is relevant information: Function of the headrest: In addition to enhancing driving comfort, the primary role of the car seat headrest is its protective function. To better protect the head, it's essential to adjust the height of the car headrest correctly. Role of the car headrest: During a collision, the human body is subjected to significant impact forces, and inertia causes uncoordinated movement between the neck and head, which can easily lead to head and cervical spine injuries. The car headrest serves as a buffer, effectively reducing injuries and providing protection. Height of the headrest: The height of the car headrest is crucial. An inappropriate height can result in more severe injuries. If the car headrest is too high, it fails to act as a buffer; if it's too low, the cervical spine is prone to fracture upon impact. The height of the car headrest should align with the head to effectively protect both the head and cervical spine. The exact adjustment should be based on the height of the driver or passenger.
