  1. 1. Development of a Mechanical Model for Rear Impacts: Evaluation of Volunteer Responses and Validation of the Model

    Författare :Johan Davidsson; Chalmers University of Technology; []
    Nyckelord :whiplash; validation; rear impact; dummy; seat; spine; rear-end collision; volunteer; BioRID; neck;

    Sammanfattning : The objective of this research has been to develop a biofidelic crash-test dummy to facilitate design of seat systems with enhanced occupant protection in rear-end collisions. These frequent collisions may cause soft-tissue neck injuries to occupants in struck vehicles. LÄS MER

  2. 2. 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. 3. Neck Injury Risk in Rear-End Impacts. Risk Factors and Neck Injury Criterion Evaluation with Madymo Modelling and Real-Life Data

    Författare :Linda Eriksson; Chalmers University of Technology; []
    Nyckelord :injury criteria; rear-end impacts; neck injuries; mathematical modelling; injury probability; head restraints; BioRID; NICmax; risk factors; WAD; car seats;

    Sammanfattning : Soft-tissue neck injuries, also termed AIS 1 neck injuries, are common after low-speed rear-end impacts. These injuries, which can be long-lasting, have increased in frequency during the past few decades. There is no consensus regarding injury mechanisms; however, injury criteria have been proposed, without yet being fully evaluated. LÄS MER

  4. 4. Neck Injuries in Rear Impacts. Dummy Neck Development, Dummy Evaluation and Test Condition Specifications

    Författare :Astrid Linder; Chalmers University of Technology; []
    Nyckelord :seat design; whiplash; BioRID; neck injuries; dummy neck; consumer test; impact severity; low-velocity; rear impact; mathematical model;

    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
