[0002] With the development of the automotive industry, consumers have increasingly higher demands for vehicle comfort. As the component that comes into direct contact with passengers, the performance of the seat has a significant impact on ride comfort. The NVH (noise, vibration, and harshness) performance of the seat rails directly affects the passenger experience during vehicle operation; noise and vibration generated by the rails will reduce ride comfort.
