This research, we conducted an injury occurrence test for a wheelchair overturned and collided for elderly people. From the results of the experiments, maximum damage assessment to the human body and survival rate were estimated. As a result, the maximum injury when falling was a side fall. Injury of AIS (Abbreviated injury Scale) 6 occurred in the head. The survival rate was found to be 0.12% in the TRISS (Trauma and Injury Severity Score) model and 0.00% in the ASCOT (A Severity Characterization of Trauma) model. The maximum injury of the collision occurred when the wheelchair was traveling at 15 km / h, caught on the curb stone, collided with the wall in front and the AIS 3 injury occurred in the head. The survival rate was found to be 72.58% for the TRISS model and 74.09% for the ASCOT model at the minimum. It was found that equipped with a helmet in all experiments reduces AIS by about 2 to 3 and has an effect of increasing survival rate.
