Aspects of Passenger Safety 700420

The kinetic energy of a passenger during the impact is transformed in deformation of the car, elongation of belts, bending of arms and legs and vulneration. The amount of energy to the different parts of the car and body depends on the possible deformation, displacement, and the tolerable values of deceleration.
The problem is studied on a model for passenger and car. Parameters are the outside and inside car-deformation, initial distance of passenger and car, active forces of the passenger, and safety-devices.
The influence of the car deformation on the required inside deformation is discussed. The initial distance between passenger and target is very important for passenger without support but of minor influence for supported passengers.
