SpletPDOF is only the direction of the crash impulse, it does not specify the damage side. For example a PDOF of 45° could as easily be a front impact as a side impact. Using PDOF as a surrogate for damage side may be appropriate in many collisions but not in others. SpletThe results of the present study indicate that occupants involved in MVCs and seated between unbelted occupants and the PDOF are at increased risk of injury, including death. This association was consistent across seating positions but limited to belted at risk occupants when adjusted for significant confounders. fish otah recipe
