Abstract: The joint angles of three most common postures of passengers sitting in the rear seats (sleeping, standard, upright) were recorded to develop an ideal posture model for rear seat passengers within a car. The passengers were positioned in a realistic mock-up of a whole car interior with a fully adjustable back seat and postures recorded. The results showed that the upright and standard postures have similarities to the postures of the driver’s seat in the literature. The relaxed posture showed a higher angle between trunk and thigh compared with the driving position and the variation in leg postures was much larger, which can be explained by the fact that the legs have more freedom in the rear seat than in the driving position.
