What are the internal structures of a car?

[OClaire]

Body internal ventilation, heating, cooling, and air conditioning devices are important equipment for maintaining a normal in-car environment and ensuring the safety and comfort of the driver and passengers. Seats are also one of the important components inside the car body. Below are the relevant introductions: 1. Interior trim parts: including surface coverings such as the dashboard, ceiling, sidewalls, seats, as well as curtains and carpets. In cars, textiles made of natural or synthetic fibers, artificial leather or multi-layer composite materials, and foam plastics with skin are widely used as surface coverings. In buses, materials such as fiberboard, cardboard, engineering plastic sheets, aluminum sheets, patterned rubber sheets, and composite decorative panels are extensively used as covering materials. 2. Seats: Seats consist of a frame, cushion, backrest, and adjustment mechanism. The cushion and backrest should have a certain degree of elasticity. The adjustment mechanism allows the seat to move forward or backward, up or down, and adjust the tilt angle of the cushion and backrest.
