1. Interaction between humans and car seats : studies of occupant seat adjustment, posture, position, and real world neck injuries in rear-end impacts
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
2. Neck Injury Risk in Rear-End Impacts. Risk Factors and Neck Injury Criterion Evaluation with Madymo Modelling and Real-Life Data
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
3. Car Safety for Children Aged 4-12 : real world evaluations of long-term injury outcome, head injury causation scenarios, misuse, and pre-crash maneuver kinematics
Sammanfattning : Child casualties in car crashes have decreased over the years. Nevertheless, occupant safety in rear seats, especially for children 4-12 years old, needs further attention because motor vehicle crashes remain the leading cause of death and long-term health consequences for children.

Sammanfattning : This thesis presents a systematic study of human responses to different motions and strategies of car body tilt control regarding ride comfort, working/reading ability and motion sickness on high-speed tilting trains. Experiments with test subjects were performed in a tilting train on curved track as well as in a moving vehicle simulator. LÄS MER
5. Neck injuries in rear impacts : Dummy neck development, dummy evaluation and test condition specifications
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
