We present two forensic autopsy cases of unbelted occupants associated with the airbag deployment in motor vehicle collisions. Both victims suffered from cardiovascular injuries which were the cause of death. Case 1: A 50-year-old man sustained a contusion on the left anterior chest with rib fractures and laceration of the intrapericardial inferior vena cava, the right ventricle, and the right pleuropericardium. Case 2: A 40-year-old man sustained multiple rib fractures, sternal fracture, and the rupture of the right ventricle. Autopsies and vehicle examinations revealed that both victims' chest seemed to strike the steering wheel through the deployed airbag. Therefore, we determined that the source of blunt impact force is the steering wheel through the airbag rather than airbag deployment only. In light of these two cases, we learned that the steering wheel should be considered as the blunt impact force inducing cardiovascular injuries even in cases in which the airbag has been deployed.
