Abstract： Autonomous driving liberates passengers from driving tasks，and allows them to choose more comfortable sitting postures. The motion responses and injuries of occupants in colisions were studied under three different sitting angles.The results show that the passengers will dive in a siting position with a large inclination angle，resulting in an increased risk of injury. In response to this phenomenon， a protective strategy of seat cushion flipping was proposed. This strategy significantly reduces the injury risk of the occupants. Under the restraint of seat belts，the liver strain of occupants in 120∘ sitting position is reduced to 42.1% ， and the heart strain of occupants in 150∘ sitting position is reduced to 24.3% ：

Key words： high angle siting position; automatic drive; front impact; passenger injury
