These parts include seating systems with integrated structural frames and energy-absorbing foams, trim panels constructed of molded plastics and textiles, and instrument panels housing critical vehicle information displays and control modules. Climate control systems utilize ductwork, blower motors, and heat exchangers to regulate cabin temperature. Safety components within this category include airbags, seatbelts, and interior lighting systems designed for visibility and emergency response. Materials are selected for durability, flame resistance, and adherence to stringent OEM specifications.
