The 755 accidents happened between 5 years about the doors of the car. The case across finger and hand was 87%. The crash force of the sliding door (231kgf) was bigger than he crash force of the hinged door (95kgf). Accidents happened "The slide door closed suddenly and got a blow across the thumb in the slope of the steep grade" and "The man broke the finger of left hand in second and third. Because of sandwiched by the door". I think that an indicator for the safety of the sliding door is necessary. I simulated a finger sandwiched with a sliding door in dynamic analysis software LS-DYNA. I made a sliding door and a finger model in this study. I confirmed the mechanism about strength of the bone and influence tof the sliding door about the speed and the mass.
