Ergonomics is a branch of science drawing from physiology, engineering and psychology studies. Basic properties of vehicle interior are described. Car seat design, upholstery fabrics and passenger safety have been particularly emphasized. Textile fabrics as products providing comfort, safety and aesthetics of the vehicle interior were dealt with. Safety belts, airbags and car seat covers were especially pointed out. Specific problems related to the safety of passengers, whose anthropometric measurements deviate from the average ones, were addressed. There are the movements of drivers while driving the car. The anthropometric data are available for ergonomic design of car driver seat.
