Head protection

A helmet is the first line of defense in crashes, but experts say it lacks flexibility to protect against angular acceleration, a leading cause of rotational head and brain injuries.

Conventional rigid protection for

high-impact collision

General helmets provide a range of protection

against head injury from high-impact collisions,

but are considered too rigid to protect against

angular acceleraton. Their standard design

consists of a hard poly-carbonate or fiblerglass

exterior and a polysterene (EPS) or expanded

Styrofoam inner layer.

How the 6D “suspension”

technology works

6D Helmets’ technology aims to reduce angular

acceleration with flexible isolation “dampers” that

reduce head rotation at impact.

The dampers also provide omni-directional shearing

in different directions, thereby reducing angular

acceleration of the head and brain.
