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

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

    Sammanfattning : 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. LÄS MER

  3. 7. Neck injuries in rear impacts : Dummy neck development, dummy evaluation and test condition specifications

    Författare :Astrid Linder; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Neck; Injury; Anthropometric dummy; Severity; Impact test; Rear end collision; Seat; Mathematical model; Velocity; Thesis; Optimization; Mathematical neck models; Rear impact tests; Biomechanics; Road: Components of the vehicle; Road: Components of the vehicle;

    Sammanfattning : The objective of the work underlying this thesis was firstly to develop a neck for a new rear impact dummy, to evaluate the complete dummy and to specify test conditions for a consumer test with attention to AIS 1 neck injuries in rear impacts. In the development of the dummy neck, a mathematical neck model was developed and evaluated. LÄS MER

  4. 8. Child Safety in Car Crashes

    Författare :Marianne Johansson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Numerical modelling; Factorial DOE; Stochastic simulation; Accident reconstruction; MADYMO; Child Safety; Restraint system; Anthropometry; Q3;

    Sammanfattning : Traffic related trauma is the main cause of child fatality and injury in Europe and North America, with the large majority of fatalities and injuries occurring to children in cars. Specifically, head injury is a common outcome in injury causing car accidents. LÄS MER

  5. 9. Characteristics of nearside car crashes : an integrated approach to side impact safety

    Författare :Cecilia Sunnevång; Maria Krafft; Mats Lindkvist; Christer Hydén; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; side impact; WorldSID; thorax; injuries; side airbag; sidokollision; WorldSID; thorax; injuries; side airbag; biomechanics; biomekanik; Epidemiology; epidemiologi;

    Sammanfattning : Introduction: Approximately 1.25 million people globally are killed in traffic accidents yearly. To achieve the UN Global Goal of a 50% reduction of fatal and serious injuries in 2020 a safer infrastructure, as well as new safety technologies, will be needed. Side crashes represent 20% of all serious and 25 % of fatal injuries. LÄS MER

  7. 10. Fatal car crash configurations and injury panorama : with special emphasis on the function of restraint system

    Författare :Mats Lindquist; Ulf Björnstig; Anders Kullgren; Umeå universitet; []
    Nyckelord :Surgery; Deep studies; fatal crashes; small overlap; human FE-modeling; body kinematics; real life safety; Kirurgi; kirurgi; Surgery;

    Sammanfattning : Background: Most traffic safety research projects require accurate real world data which is collected in different databases around the world. This is especially important since the results of these projects form the basis for new crash test procedures and standards. LÄS MER
