Abstract

A head-ring concept is described to control head and neck kinematics during torso restraint for the disabled in a collision. A prototype head-ring was evaluated in 48 km/ph sled tests, and Madymo simulations were run to optimise the restraint characteristics. The combination of head-ring and lap-shoulder belts reduced head acceleration 18% (47g vs 57g) and chest acceleration 36% (42g vs 66g) over conventional torso restraint. More uniform, whole-body deceleration improved head and neck kinematics. Head restraint in frontal crashes is a promising concept to experimentally study. It may aid transport of the severely disabled or frail. One approach is to integrate it with safety belts in the seat or wheelchair. Further development and mathematical analysis may lead to more practical head-ring systems.
