New helmet designer claims unsafe deficiencies in standard designs

Blake Witherow of the Royal Melbourne Institute of Technology says that his new 'Regenerative Helmet' overcomes many of the problems of ordinary helmets, which he says are often ill-fitting and unsafe.

Witheroe says his research showed current bicycle helmets exposed several deficiencies, including user fitting errors (some even worn backwards) and material deficiencies. Expanded Polystyrene (EPS) liners inside many helmets can shatter at impact and provide less impact absorption after multiple impacts. He also says the aggressive styling of some helmets can be damaging to cyclists’ heads and necks on impact and also loose-fitting helmets can dislodge before impact, causing another set of injuries.

Witheroe’s helmet avoids large protrusions and creates a rounder profile. The hard outer shell serves two purposes - to distribute load over a large area thereby reducing the hardness of the liner, and to decrease friction with the road surface.

He believes more durable liners will increase the product life cycle considerably and should provide protection in the case of multiple impacts within the same accident.
