In many vehicle accident investigations, it is necessary to know not only the speeds and motions of the vehicles involved, but the causes of injuries suffered by their occupants as well. Such investigations seek to answer questions regarding occupant ejection, effects of seatbelt use, airbag deployment and body-interior impacts. Such answers can sometimes be found through simple analyses, or they may require advanced three-dimensional simulations and computer modeling techniques. Once an analysis of this type is complete, it is often necessary to generate drawings or animations to communicate the findings to a judge, jury or mediator.

Expertise

Questions Answered

We have significant experience in many aspects of occupant dynamics including:
  • Determining the effect of seatbelt slack and stretch and airbag deployment upon occupant injuries
  • Determination and calculation of Head Injury (HIC) and other injury criteria
  • Computer simulation and animation

Case Examples

SUV Rollover Ejection:
A woman driver was seriously injured when her SUV was struck sideways by a car causing her vehicle to roll over. The SUV driver was ejected because she was unbelted. The defense claimed that, based upon statistical studies, she would not have been injured if she had been belted. We demonstrated that her major injuries were caused by her impact with the door interior, which would have been inflicted even if she had been belted and was not ejected. The case settled in the plaintiff's favor.

Forensic Clues: Ladder Accidents Part 2 - Extension Ladders

By: John Ryan, BSME, PE

This issue of Forensic Clues is the second installment of an examination of ladder accidents. Last month we explored stepladders, this month we will be discussing extension ladders. Ladder accidents are a very common occurrence. Over half a million people annually seek medical attention due to ladder accidents. Over three hundred people are killed yearly in these often preventable accidents. This is a serious problem.
