Occupant Safety

Restraint System Analysis
The way an occupant moves inside the vehicle, also known as occupant kinematics is an important part of injury causation. Over the years various safety measures have been implemented and refined in an effort to improve occupant safety and minimize the potential for injuries. These safety measures include lap and shoulder belts, pretensioners, load limiters, frontal airbags, side torso airbags, side curtain airbags, energy absorbing steering columns, knee bolster airbags, among others. Under certain crash conditions, some safety measures may be of benefit to the occupant, while other crash conditions, such as those with substantial intrusion or penetrating exterior objects, there may be little or no benefit to the occupant.
The experts at BioRec® have multiple years of experience analyzing occupant and vehicle kinematics and can help explain potential injury mechanisms in both high speed and low speed vehicular collisions. Some of the investigations the experts at BioRec® have performed include,

  • Determination of seat belt use/ nonuse
  • Potential injury mitigation or prevention through proper seat belt use
  • Examination of pre-impact posture, body size and habitus on injury outcome
  • Examination of seat belt webbing, anchor points and hardware for proper operation
  • Photographic documentation of biological evidence and/or interior contact marks
  • Occupant trajectory analysis and determination of ejection portals
  • Who was driving determination
  • The role of roof crush on injury outcome
