【Abstract】A studywasconductedonthecolisionsafetyof passengers with“zero gravity”seats at different deployment angles.Firstlyfrotalcollonmodelofteeicleistabld，ndteatanglesereusedtoandardueer gravity siting posture，and the backrest angle was adjusted to three different postures of 120∘ ， 150∘ ，and 180∘ based on the standard posture. Then，two collision speed curves of 40km/h and 56km/h were applied to the model， respectively. Simulation comparisonshowsthattheinjuryvaluesoftheocupant’shead，neck，andchestarethesmalestinthestandardposture.The injuryvaluesof theoccupant’sheadandneckarethelargestinthezero-gravityposture.Theriskofchestinjuryincreases with theincrease ofpostureangle.Thechestundergoes compresiondeformation，andthelungs are most susceptible tocontusion， followed bythe liverandsplee.Theincreaseintheinclinationangleofthepassengers increases theriskofseveredivingand “secondary collision”of the lower limbs.
