Abstract/Description: The research investigated the effect of aging altered driving posture on injury criteria of the head (HIC15) and chest (peak resultant chest acceleration) in low speed frontal impact. The aging altered driving postures were described in terms of body joint angles. Older drivers exhibited smaller body joint angles meaning older drivers tended to sitting closer to the steering wheels compared to their younger counterparts. A simplified anthropomorphic test dummy, sled rig, and impact pendulum were constructed as the necessary testing apparatus for the low speed frontal impact sled test experiment. A fractional factorial design screened out the significant factors that affect HIC15, and peak resultant chest acceleration. The results showed that for HIC15, torso angle, hip angle, right knee angle, right ankle angle, and seatbelt pillar loop anchor height were the significant factors. For peak resultant chest acceleration torso angle, right knee angle and left ankle angle were significant. Qualitatively, extended torso angles, meaning sitting more laid back, increased both HIC15 and peak resultant chest acceleration. Left and right side of lower extremities altered HIC15 and peak resultant chest acceleration separately. These findings may help to better understand biomechanical response of older drivers during car accidents and provide useful information regarding safer vehicle design, such as occupant seat and seatbelt in an effort to mitigate injuries.
