  1. 1. 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

  2. 2. Seat integrated safety belts : a parametric study using finite element simulations

    Author : Anders Gavelin; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Abstract : In recent years an increasing interest has evolved concerning seat integrated safety belts in cars, regarding both 3- and 4-point belts in various configurations. One safety advantage of seat integrated safety belts appears in the case of so-called small overlap crashes. READ MORE

  3. 3. The Swedish birth seat trial

    Author : Li Thies-Lagergren; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Evidence for the safety of upright birth positions in relation to maternal blood loss and perineal outcomes is inconclusive. Little is known about the impact of upright positions on the use of synthetic oxytocin for augmentation of labour or whether an upright birth position in the second stage of labour can reduce the number of instrumental vaginal deliveries.

  4. 4. 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. 5. 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
