Samenvatting
Rear-end impacts involving Volvo cars from 1999-2002, including 1221 front seat occupants (above 14 years of age and without prior neck problems), are investigated with respect to AIS 1 neck injury rate differences between those in WHIPS seats as compared to those in previous Volvo seats. The differences with respect to gender are explored. The AIS 1 neck injury reducing effect of WHIPS compared with previous Volvo seats is 31 % for initial neck symptoms and 51% for neck symptoms lasting longer than one year. The injury reducing effect is higher for women than for men. No clear explanation for the gender differences was found with respect to occupant size. For the covering abstract see ITRD E141807.
