Occupant Restraints / Biomechanics
Airbags, seat belts, and the seat itself all play a role and must function together to properly protect occupants when a vehicle is involved in a crash. With accidents that involve personal injury, the question of whether safety restraints were in use and whether they performed properly must be considered.
The experts at Wolf understand how these systems function as well as the physical and electronic evidence that may be employed to determine how well the restraint system worked. Many newer vehicles are equipped with on-board recording devices (event data recorder or “black box”) which may provide the investigator with useful information about the crash and assist in the analysis. Knowing how to gather information from the vehicle without destroying evidence is an important element of investigating incidents where effectiveness of occupant restraint may be an issue. Wolf personnel have gained this knowledge through training and experience.
Wolf’s long history of analyzing road vehicle restraints has proved invaluable to Wolf in its research work on restraint systems for military aircraft. Newer cars have side or rollover air bags in addition to frontal air bags for the driver and front seat passenger. Some also include seat belts that tighten down against the occupant to more securely restrain him in a crash.
