Low Acceleration Time Extended Events
Initial testing is examining "unaware rear-seated passengers" in several different conditions:
- Baseline - no bracing, restrained in a typical rear seat belt in a typical rear seat
- Bracing and restrained in a typical rear seat belt in a typical rear seat
- No bracing and restrained in a more advanced front seat belt (i.e., with load limiters and pretensioners) in a typical seat
- No bracing and restrained in a more sculpted seat
Video, electromyography (EMG, a measure of muscle activity), and motion capture data is captured on each test subject in all conditions. Initial data suggests that participants who brace for swerving have little visible movement, while the EMG data shows their muscles and tendons actively responding to the swerving.
