· High Fire Performance: The seat's elastic materials are filled with polyurethane graphite sponge, a primary component of the seat. Based on excellent mechanical performance, the fire performance reaches EN45545-2 standard HL2 level, and the fire resistance of the complete seat meets EN45545-2 standard HL3 level, fully meeting the fire safety requirements for train passenger seats.
· Low Noise for Rotating Seats: Rotating seats use anti-noise devices to reduce rebound forces, and under the matched design of the damper and spring, they achieve rapid recovery and low noise in the seat position
