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

   Author : Astrid Linder; Chalmers University of Technology; []
   Keywords : 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;

   Abstract : 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. READ MORE

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

   Author : Johan Davidsson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; whiplash; validation; rear impact; dummy; seat; spine; rear-end collision; volunteer; BioRID; neck;

   Abstract : 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. READ MORE

5. 3. Effects of Seat and Seat-Belt Design on Car Occupant Response in Frontal and Rear Impacts A Study Combining Mechanical and Mathematical Modelling

   Author : Gert Nilson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; frontal impact; MADYMO; whiplash; rear impact; belt-in-seat; force-limiting; mathematical simulation; car seat; submarining;

   Abstract : The objective of the present work is to determine the potential injury-reducing benefits to car occupants in accidents of seat and seat-belt design. The main problems addressed are the risk of injury to head, neck, and upper torso in frontal impacts, and the risk of minor neck-injuries - whiplash-injuries - in rear-end collisions. READ MORE

6. 4. Child Safety in Car Crashes

   Author : Marianne Andersson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reconstructions; near-side; evaluations; frontal impact; rigid body; mathematical simulations; rear seat; finite elements; belt positioning booster; side impact; child safety; child seat;

   Abstract : Traffic related trauma is the most common cause of fatality and severe injury to children in developed countries. The majority of these fatalities and injuries are caused by frontal and side impacts. READ MORE

7. 5. 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
