Simulate Uniform Restraint Concept for Wide-Ranging Crash Protection
Seatbelts and airbags have been proved to be effective restraint devices for vehicle occupant impact protection. However, a seatbelt provides concentrated force on the occupant chest, which may be disadvantageous to elderly occupants. Airbags can spread the force on the occupants, but it could also generate disproportional risks to small or out‐of‐position occupants. A uniform restraint concept is proposed in this study. The concept lies in providing spread and constant restraint forces on the knees, thorax, shoulders and head, respectively. Those are relatively sturdy parts of the human body. This study builds on previous work by exploring how the uniform restraint concept controls occupant posture during impact and how it works in different impact severities. A finite element human body model (HBM) in a seated driving position (Academic THUMS Version 4.0.1 for LS‐DYNA) was used in this study. The simulation results show that the uniform restraint can provide good protection. By making the restraint forces changeable, the system can be adaptive to different crash severities and occupant body sizes.
