Experimental Head Injury Investigation of Head Impact Caused by Unsecured Object in Vehicle during Vehicle Frontal Crash

abstract

English

Occupant safety in the realistic car crash accident is typically solved as a problem of human body interaction with airbags and vehicle structure (vehicle seats, vehicle body parts, and others). There is also a situation when an unsecured object placed in the vehicle causes the injury of the vehicle occupant. The unsecured object can be described as a bottle, tablet, or laptop. These unsecured objects are acting in the vehicle during its crash like projectiles, and they have a very significant potential to harm the vehicle occupant if they interact with their bodies. An experimental investigation was performed to explain what can happen if the unsecured object interacts with the human body and what is the injury risk if this case happens. As a critical human body part was selected human head and as the traffic accident situation was taken frontal vehicle impact. The hypothesis on which the whole experimental project was build on takes into account: The human head rear part interacts only with the unsecured object and nothing else (airbags, etc.); The seat head restraint is not present; The unsecured object is stiff and has initial speed during the crash similar as the vehicle crash velocity (friction effect is negotiable); The injury effect is blunt.
