Restrain the occupant is one of the five principles of vehicle crashworthiness. It is the job of seat belts and airbags working in tandem to prevent occupants from hitting the interior of the vehicle or from being ejected.
When an accident ejects an occupant from a vehicle, there is 13 times higher risk of injury to the person throw out when compared to the people that remain inside the car.
Ejected occupants suffer severe head injuries, spinal fractures, crushed torso injuries, and death.
Accident investigators often mistakenly conclude that an ejected person was not wearing their seatbelt. Here’s why.
- Police officers lack the necessary engineering, medical and forensic training to accurately determine seatbelt use.
- Police officers do not have the time to properly analyze the physical, medical and forensic evidence to accurately determine belt use.
- Police officers routinely rely solely on the word of people in the vehicle as to whether they were belted rather than conduct a detailed seatbelt investigation.
We know that seatbelt buckles unlatch during crash tests because physics tricks the spring mechanism into releasing the belt.
The defective buckle is shown in the video below.
Seat belt retractors are supposed to lock and stay locked during an accident. However, defective retractors unlock in rollover accidents. It allows the belt to spool loose and let the occupant rollout of their seatbelt.
They fly out of the vehicle with catastrophic results, or their flailing loose arms and legs outside the vehicle get crushed or cut off.
The Tracy Law Firm’s Crash Lab conducts a thorough analysis of the physical, medical, and forensic evidence. We microscopically examine the seatbelt’s webbing to prove that a defective restraint system caused wrongful death or catastrophic injuries.
Dr. Mariusz Ziejewski, a professor of mechanical engineering, and expert in our crashworthiness cases, explains in this video.
Defective Side Curtain Airbags Fail To Prevent Occupants From Being Ejected
A side curtain airbag is supposed to keep a person’s head, arms, legs, and upper torso inside the passenger compartment during an accident. However, we represent catastrophically injured victims ejected because a defective side curtain airbag failed to deploy.
The biggest problem with side curtain airbags is defective sensor placement and electronic programming to detect the severity of the crash. Other issues include side airbags that do not fully cover windows and side panels.
Doors Have Been Flying Open In Crash Testing Since The 1930s
Even if the driver or passenger is wearing their seatbelt, their risk of ejection or partial ejection increases when a defective door flys open.
Ejection remains a high-risk today because many automakers use poorly designed door systems. The causes include defective door latches, door strikers, handles, sliding doors, and composite materials.
Todd Tracy explains in the following two videos that you may have grounds for a lawsuit if the door flew open and occupants suffered death or catastrophic injuries.
