Abstract
Sled tests were conducted with some seats which had different characteristics to understand the relationships between occupant motion and seat characteristics in lowspeed rear impacts. The position of the head restraint and the stiffness distribution of the seatback were selected as parameters expressing seat characteristics. Volunteer's cervical vertebral motions were photographed with an x-ray cineradiographic system at a speed of 90 frames/sec as well as the visible motions of dummy's and volunteer's were recorded. The results indicated the head restraint position and upper seatback stiffness influenced occupant motions. Correlations between visible motions, such as ramping-up, retraction and extension, were also analyzed and some correlations were found.
