Safety Belts
Spit Testing Performed by Dr. Paver at BEI | Publications
Spit testing was performed with human volunteers to compare the effectiveness of seat belt pass-through v. cinching latch plates. Findings include:
1. Much less head excursion resulted with the cinching v. pass-through latch plate.
- Pass-through latch plate: Slack from the belt slipping from the shoulder immediately passed through to the lap belt, resulting in greater head excursion.
- Cinching latch plate: There was no pass-through and much less head excursion resulted.
Wonder Wheel: The first inverted living human vertical studies to be scientifically documented and reported. It was found that no head or neck injuries resulted from drops of up to 91 cm and velocities up to 4.2 m/sec for restrained occupants in the absence of roof crush. Publications
