Abstract and keywords

The objective was to study the effectiveness of whiplash protection concepts in cars due to gender and the effectiveness of various concepts based on real-world injury outcome. In the study the influence on whiplash symptoms lasting longer than one month and those leading to permanent medical impairment was studied. In average the existing whiplash concepts were more effective for males than females. The risk reduction regarding permanent medical impairment was approximately 45% for females and approximately 60% for males. RHR in Saab, Volvo WHIPS and Toyota WIL, all had approximately 50% lower risk of whiplash injuries leading to permanent medical impairment compared to cars with standard seats.
