Abstract: Described herein is a system for redirecting head impact force to other portion or portions of a body of a person. The system includes a harness wearable on upper body or both upper and lower body of the person and permitting motion of the person; a force redirecting element configured to connect the harness to a helmet wearable by the person; and a motion limiting unit connected to the force redirecting element, wherein the motion limiting unit can be triggered by the impact and limit the load on the neck of the person. The system also includes stiffening units to pre-tension the harness and increase the effective impedance of the system.

Abstract: Described herein is a wearable device for redirecting head impact force from the head of a person to other body part or parts of the person, the device comprising: a helmet wearable on the head of the person; a brace wearable on the body of the person; and at least one force redirecting unit configured for connection to the helmet and the brace, wherein at least one of the force redirecting unit is configured to be compressed to carry compressive load, and at least one of the force redirecting unit is configured to be extended to carry tensile load.
