2. 1. Interaction between humans and car seats : studies of occupant seat adjustment, posture, position, and real world neck injuries in rear-end impacts

   Author : Bertil Jonsson; Ulf Björnstig; Mats Svensson; Anders Kullgren; Umeå universitet; []
   Keywords : Surgery; backset; Whiplash; rear-end impact; seated posture; seated position; bioRID; Kirurgi; Surgery; kirurgi;

   Abstract : Background: The latest generation of rear-end whiplash protection systems, as found in the WHIPS Volvo and SAHR Saab, have reduced injury rates by almost 50% in comparison with the previous generation of seat/head restraint systems. Occupant behaviour, such as seated posture and seat adjustment settings, may affect the injury risk. READ MORE

4. 2. Female and Male Whole Spinal Alignment and Cervical Kinematic Responses in Rear Impacts

   Author : Fusako Sato Sakayachi; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; neck injury; spinal alignment; whiplash; cervical vertebral kinematics; volunteer; Multi-Dimensional Scaling; rear impact; automotive seated posture; MRI; female;

   Abstract : The susceptibility of women to Whiplash Associated Disorders (WADs) has been the focus of numerous epidemiologic studies. Summarising the epidemiologic WAD studies, women were found to be at three times higher risk of sustaining WADs than men. READ MORE

5. 3. On neck load among helicopter pilots : effects of head worn equipment, whole body vibration and neck position

   Author : Marcus Thuresson; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Biomechanics; cervical spine; electromyography; head-worn equipment; helicopter pilots; laboratory; male; mechanical load; neck load; night vision goggles; rotary wing pilots; statistics; transmissibility; whole body vibration.;

   Abstract : Introduction: Helicopter pilots complain of pain originating from the neck region. The causes are still basically unknown, but the ergonomic situation when flying a helicopter, with unfavorable load caused by static neck and body positions, whole-body vibration and heavy head-worn equipment, has been suggested as a risk factor.

6. 4. Child Passenger Kinematics in Emergency Manoeuvres

   Author : Isabelle Stockman; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : ABSTRACTIn motor vehicle impacts, a child’s head is generally the most frequently injured body region, irrespective of impact direction. Head to front seat back impact has been identified as a predominant cause of injury for rear seated, seat belt restrained children, aged 3 – 13, who sustained AIS2+ head injuries in frontal impacts.
